WHMCS Modules and Themes I Built
136 modules and themes for hosting companies and IPTV operators; each page lists the WHMCS and PHP versions it needs. One-time price, a lifetime license and a year of updates and support. Need something that is not here? I build custom WHMCS modules, custom WHMCS themes and a WHMCS app for Android and iOS too.
SM Reseller Hub: White-Label Reseller Platform for WHMCS
SM Reseller Hub lets your WHMCS clients resell hosting, servers, licences, SSL and domains under their own brand. They get a white-label store and client area on their own domain, a REST API for their own website and a reseller dashboard, while you keep control of prices, margins, payments and every customer.
IPTVSpire IPTV Storefront Theme for WHMCS
IPTVSpire turns WHMCS 9 into a complete storefront for a streaming subscription business: a TV-style homepage, plan cards with a free trial, separate features, devices and reseller pages, and a restyled login and cart. See it running on the live demo.
Standalone IPTV Reseller Billing Portal
I built this portal for IPTV businesses that do not want to bend WHMCS to fit. It runs on your own server, connects to NXT, Strong8K and XUI panels, and handles credits, sub-resellers and line activation for one flat price.
Abandoned Cart Recovery Emails for WHMCS
I built this module to win back WHMCS orders that stall at checkout. It detects abandoned carts, sends an email sequence you write, can add a discount code, and reports which emails bring buyers back.
MagizAI AI Chatbot Module for WHMCS (Free)
The module is free. It needs WHMCS 8.0 or newer and a MagizAI plan, from $10 a month. Built for web hosting companies and IPTV operators.
Bulk Edit and Mass Update Tool for WHMCS
An admin-only WHMCS module I built for changes too large to click through and too risky for raw SQL. Filter the records, preview the result, apply it as a background job, and reverse it later if needed.
Cloudflare Zone and DNS Reseller Module for WHMCS
I built this module to sell Cloudflare as a WHMCS product. Zones are created on order, customers manage DNS records, cache, page rules, firewall rules and SSL from your client area, and you bill per zone or per plan.
Self-Service cPanel Transfer Wizard for WHMCS
I built this wizard so customers can move their own sites from another cPanel host to yours without a ticket. It uses WHM API tokens, never root passwords, and checks the site, mail and DNS after the move.
Discord Bot and Role Sync for WHMCS
I built this Discord bot to link your community server to WHMCS. Roles follow active products, paid-only channels open on payment and close on cancellation, and customers use slash commands for invoices, services and support.
Free and Paid Trials Module for WHMCS
I built this module to put proper trials on WHMCS products: free for a set number of days, a small paid trial, or freemium with limits. Trials convert or suspend automatically, and reports show which ones turn into paying customers.
Hetzner Cloud Provisioning and Auto-Sync for WHMCS
I built this Hetzner Cloud module so your WHMCS catalog never falls behind Hetzner. Server types, locations and prices sync hourly with your markup, and customers manage power, console, snapshots, networks, firewalls and volumes.
Hourly Billing and Time Tracking for WHMCS
A WHMCS module I built for selling time. Staff and clients log hours against a service, each service carries its own hourly rate, and WHMCS raises the invoice from the time log without manual math.
KYC Identity Verification Module for WHMCS
I built this KYC module to stop fraudulent signups before anything is provisioned. Customers upload ID and address proof, you review them in a queue or by API, and documents stay encrypted on your own server.
SMS, Chat and Email Notification Hub for WHMCS
One WHMCS module I built to send notifications across eight channels from a single rules screen. You decide which events go where, customers set their own preferences, and failed messages fall back to email.
NOWPayments Crypto Payment Gateway for WHMCS
A WHMCS payment gateway I built on the NOWPayments API. Customers settle invoices in any of more than 100 cryptocurrencies, and WHMCS is told as soon as the payment is verified.
QuickBooks Online Sync Module for WHMCS
A two-way connector I built between WHMCS and QuickBooks Online. Invoices and payments sync in both directions, new customers are created in QuickBooks for you, and each run is logged.
Reseller REST API Module for WHMCS
I built this module to give your resellers and partners keyed, rate-limited REST access to WHMCS orders, clients, invoices and products, so they can run their own storefronts on top of your catalog.
Reseller Sub-Accounts Module for WHMCS
I built this for hosts that sell through resellers. Each reseller manages unlimited sub-clients inside their own account, those clients stay off your WHMCS client count, and you set margins, products and branding per reseller.
Security Hardening and Recovery Module for WHMCS
I built this module to harden a WHMCS install. It spots and blocks exploit attempts, enforces 2FA, scans for malware, sandboxes third-party addons and themes, and takes secure backups you can restore in one click.
SM Square: Square Payment Gateway for WHMCS
SM Square takes every Square payment method on your WHMCS invoices and adds a Payments Manager to your admin area: who paid, Square fees, refunds, saved cards, webhooks, disputes, debug logs and a live sandbox test suite.
Telegram Support and Billing Bot for WHMCS
A Telegram bot I built that runs inside WHMCS as plain PHP. Customers use commands to see invoices, services and tickets, renew and pay; admins get push alerts and can search, assign and reply from Telegram.
Vultr Cloud Server Provisioning for WHMCS
I built this module to resell Vultr through WHMCS. A paid order deploys the instance in the plan, region and OS the customer chose, and they get power controls, console, snapshots and rDNS without seeing Vultr.
WhatsApp Cloud API Messaging for WHMCS
I built this module on Meta's WhatsApp Cloud API so WHMCS can message customers on WhatsApp and take their replies back as tickets. Templates, opt-in and conversations are all handled from WHMCS.
Xtream UI Billing and Line Automation for WHMCS
I built this module to tie WHMCS billing to an Xtream UI panel. Paid orders create lines with the right package and bouquets, unpaid ones are suspended, and reseller accounts and credits are handled across multiple servers.
XUI IPTV WHMCS Module
A WHMCS provisioning module I built for the XUI panel, often called XUI One. It creates accounts after payment, assigns the right package, handles suspension and termination, and gives customers a client area for their service.
AI Domain Name Suggestions for WHMCS
I built this module so a WHMCS domain search does not stop at taken. It reads the customer's keywords and type of business, suggests keyword and brandable names, checks each one across several extensions, flags premium names and shows the price of every result.
Automatic Credit Top-Up for WHMCS
I built this addon for a cloud host that bills usage against prepaid account credit. Each client picks a minimum balance and a top-up amount; when their credit falls below it, the module charges their saved Stripe card and adds the credit. Clients can also ask for a low balance email instead.
Cash App Payment Gateway for WHMCS
I built this gateway so customers in the United States can settle WHMCS invoices with Cash App. Payments are checked and applied to the right invoice, payment requests go out by email, and anything that does not match waits for an admin to reconcile.
Client Credit Score and Payment History Addon for WHMCS
I built this addon to turn each client's payment record in WHMCS into a credit score and a history you can act on. It raises late payment alerts, manages credit limits per client and shows the picture on an admin dashboard, using scoring rules you set.
Client Transfer and Merge Module for WHMCS
I sell this module to hosts who take over another provider's customers, fold brands into one WHMCS or clean up duplicate accounts. It moves a client with services, billing history and tickets as one unit, checks the data as it goes, and can undo a transfer.
Cloud VPS WHMCS Theme
I built this theme for a company selling dedicated servers, VPS and cloud compute through WHMCS. It restyles every client-facing page, adds a catalog-style order form with a sign-in step, and ships a Theme Manager addon with CMS pages, a blog, menus, media and SEO settings.
Cloudflare DNS Automation Module for WHMCS
I built this module for hosts who run customer DNS on Cloudflare. WHMCS creates the zone when a service or domain is set up, adds the records from your template, lets customers edit their own records in the client area, and pushes one change to many zones at once.
Clover Card Payment Gateway for WHMCS
I built this gateway for businesses that run Clover in their shop and bill online in WHMCS. Cards are charged through the Clover API, saved as tokens for renewals, and payments can be refunded or voided without opening the Clover dashboard.
Configurable Option Price Manager for WHMCS
I built this addon for hosts that agree special rates on add-ons such as extra memory, IP addresses or storage. Set a price for one client, a client group or a custom rule, and WHMCS bills that price automatically while everyone else keeps the standard rate.
Cosmotown Domain Registrar Module for WHMCS
I built this registrar module to connect WHMCS to the Cosmotown Reseller API. It registers, transfers and renews domains, manages nameservers, contacts, lock, ID protection, EPP codes and DNS, and copes with Cosmotown's delayed registrations without risking a second order.
Cudo Compute GPU and CPU Cloud Module for WHMCS
I built this module to sell Cudo Compute virtual machines through WHMCS. Customers pick a data center, GPU model, vCPUs, memory, disk and image, the VM is created on order, and its hourly cost plus your markup comes out of their prepaid credit.
Custom Field Bulk Manager for WHMCS
Adding the same custom field to forty products in WHMCS means forty trips through the product editor. I built this addon to create, assign, update and delete product custom fields across many products in one go, with export and import for backup or migration.
Customer Feedback, CSAT and NPS Module for WHMCS
I built this addon to collect client feedback inside WHMCS. Clients rate you, pick a category and write a message; your team replies, tags, assigns and opens tickets from an admin inbox, with CSAT or NPS scores and trends on an overview page.
DATEV Export for WHMCS
I built this DATEV export for a German hosting company. It turns a month of WHMCS invoices into an EXTF posting batch with the right revenue account for each country and VAT case, shows every posting before export, and can zip all invoice PDFs for the tax advisor.
Email Marketing Campaigns Module for WHMCS
I built this addon to run email campaigns from inside WHMCS. You build segments from client data, pick one of thirteen layouts, check deliverability, then send in throttled batches from the WHMCS cron, with consent rules, unsubscribes and open and click stats.
Free and Trial Checkout Control for WHMCS
I built this addon because people abandon a free signup when checkout asks how they want to pay. Mark products as free or trial, and when the cart holds only those, WHMCS skips the gateway choice, shows your button text and badge, and closes the zero invoice.
FreedomPilot Operations Suite for WHMCS
FreedomPilot is the operations module I sell for larger WHMCS installs. It adds a visual rule builder, revenue and churn reporting, customer lifecycle workflows, a bulk runner with dry run and undo, finer admin permissions, a webhook bus and an optional AI ticket assistant.
Geo Currency by Visitor Country for WHMCS
I built this addon so first-time guests see prices in the currency of their country. It reads Cloudflare's country header once per session, maps it to a WHMCS currency you choose, and never overrides a visitor's choice, a client's account currency or a filled cart.
German Invoice PDFs (§ 14 UStG) for WHMCS
I built this addon for a German hosting company that bills in WHMCS. It draws every invoice and correction PDF with seller and buyer details, service periods, tax per rate and the right VAT note, and it flags WHMCS settings and number gaps a tax office would question.
German Legal Compliance Addon for WHMCS
I built this addon for a hosting company selling to consumers in Germany. It logs which version of your terms, privacy policy and cancellation policy each customer agreed to, gives customers an online withdrawal form, and adds receipt time and contract end to every cancellation confirmation.
GPU Server Ordering and Slack Fulfillment Module for WHMCS
I built this module for a host reselling dedicated GPU servers that are set up by hand. It creates the GPU products for you, posts every paid order to Slack, and lets your team complete or decline it there while WHMCS updates the service and emails the customer.
Helium (HNT) Crypto Payment Gateway for WHMCS
I built this gateway so WHMCS can take Helium (HNT) payments wallet to wallet, with no payment processor in between. It quotes the HNT amount at a live rate, looks for the matching transaction on chain, and marks the invoice paid once your confirmation count is reached.
hosttech Domain Reselling Registrar Module for WHMCS
I built this registrar module for a hosting company that resells domains through hosttech's domain reselling, which runs on the CentralNic Reseller API. It registers, transfers and renews domains, manages contacts and glue records, and recalculates WHMCS domain prices from purchase costs every day.
Invoice Pay Links Without Login for WHMCS
I built this addon so clients can pay straight from the invoice email. Each link opens a pay-only login for one invoice: its payment pages and PDF, nothing else. Links expire, stop working once the invoice is paid, and staff can copy, email or revoke them.
IPTV Bouquet Selection Addon for WHMCS
I built this addon so IPTV customers choose their own bouquets: by group at checkout, and again from the service page later. Each choice is saved on the WHMCS service, and history lists show staff which new orders and changes to apply.
IT and Development Services Delivery Module for WHMCS
I built this module to run service orders inside WHMCS. Each order gets a project with a checklist, messages, files and a work log, customers hand over site and server access through an encrypted form, and prepaid hour packages count down as you log time.
Low Credit Balance Email Alerts for WHMCS
I built this addon for hosts whose clients pay from prepaid account credit. Each client sets their own low balance threshold in the client area, and WHMCS emails them an alert with an Add Funds link when their credit drops below it, without repeating too often.
Manual Service Renewal Addon for WHMCS
I built this addon for hosts whose customers want to renew before WHMCS sends the renewal invoice. A Renew button on the service page creates the invoice at the right price, and once it is paid the due date moves forward and the login stays the same.
MarketPilot AI Email and WhatsApp Marketing for WHMCS
MarketPilot is my marketing suite for WHMCS. It turns your clients into segments such as dormant or at risk of churn, sends email and WhatsApp campaigns at a safe pace, writes copy with Claude if you add a key, and shows how much paid invoice revenue each campaign brought in.
Moneybird Billing Integration for WHMCS
I built this module for a hosting company that bills through Moneybird instead of WHMCS invoices. Orders and renewals become Moneybird sales invoices, payments come back by webhook to activate services, and clients can pay now, by SEPA direct debit or on a monthly invoice.
NXT IPTV Panel Module for WHMCS
I built this module and its dashboard addon to run an NXT panel from WHMCS. Paid orders create streaming lines, MAG or Enigma2 devices and reseller accounts, unpaid ones are suspended, and resellers sell from their credit balance in the client area.
Pay by Invoice Gateway with Moneybird for WHMCS
I built this gateway and addon for a hosting company whose business customers pay on account. Approved clients pick invoice payment, the invoice is created in Moneybird with a matching contact and sent from there, and staff see the sync status in WHMCS.
Payment Authorization and Chargeback Evidence for WHMCS
I built this addon for hosts tired of losing chargebacks. Before checkout or an invoice payment, the customer ticks a box and types their name. The module stores the signature, IP address, browser, amount and exact agreement text, fingerprints the record, and prints a certificate you can send with a dispute reply.
Payment Method Discount Addon for WHMCS
A small WHMCS addon I built to steer customers toward the payment methods that cost you least. Tick the gateways that earn a discount and set one percentage; the invoice gets a discount line when one of them is chosen and loses it when another is.
PayPal Subscription Payment Sync for WHMCS
When a PayPal webhook fails, the renewal is paid in PayPal but stays unpaid in WHMCS, and the service heads for suspension. I built this addon to read PayPal's transaction records on a schedule, match each payment to its customer and invoice, and record it.
Per-Client Resource Pricing Manager for WHMCS
I built this addon for providers who quote every customer separately. You set each client's unit prices for your configurable options, monthly and yearly, in their currency. The cart, invoices and upgrades use those prices, and clients cannot order until you approve them.
Product Purchase Limit Addon for WHMCS
I built this addon for hosts whose trial and promo products get ordered again and again by the same account. Pick the products to limit, set how many times one account may buy each, and checkout stops the extra order with your own message.
Proxmox VE VPS Provisioning Module for WHMCS
I built this module to run a VPS business on your own Proxmox VE hardware from WHMCS. It creates KVM machines and LXC containers from ISOs or templates, assigns IPs from a pool, picks the cluster with the most free resources and gives customers power, console, reinstall and backups.
Ray Cluster Provisioning Module for WHMCS
I built this module for providers who sell Ray, the open-source framework for distributed Python and AI work. The customer picks how many servers they want, the module creates them, installs Ray over SSH, joins the workers to the head node and bills each hour from prepaid credit.
Referral and Affiliate Program for WHMCS
I built this referral program for a hosting company on WHMCS 9. Each affiliate gets a link and a matching discount code, commissions come from paid invoices after a hold period, refunds and fraud reverse them, and payouts go out as account credit, PayPal or crypto.
Regery Domain Registrar Module for WHMCS
I built this registrar module to connect WHMCS to the Regery partner API. It registers, transfers and renews domains, manages nameservers, contacts, lock, WHOIS privacy, DNS, email forwarding and glue records, and imports Regery's TLD prices into WHMCS.
SEPA Direct Debit Gateway for WHMCS
I built this SEPA Core direct debit module for a hosting company in Germany. Customers grant a mandate, every invoice email carries the pre-notification, and you download a pain.008 file for your bank. Bookings, return debits and expired mandates are tracked in WHMCS.
Server Location Picker with Flags for WHMCS
I built this addon to manage server locations in one place. It writes them into WHMCS as a configurable option with prices in every currency, passes the chosen location code to your server module, and feeds flag cards and per-month savings to the order form.
Service Upgrade and Migration Addon for WHMCS
I built this addon for the day you move customers to a new platform. Each current service gets an offer, customers start the new service with one button, free or after paying, their login carries over where the server allows, and old services and unpaid invoices close in bulk.
SMThemes Hosting and Domains WHMCS Theme
I built SMThemes for hosting and domain sellers on WHMCS 9.1. It is a child theme of Nexus with sales pages for each product line, a client area rebuilt around services, domains and billing, a two-step order form, a settings addon and a client DNS record editor.
SMThemeTV IPTV Streaming WHMCS Theme
I built SMThemeTV for IPTV and streaming subscription sellers on WHMCS 9. It gives the client area a dark, cinematic look, builds homepage plan cards from your WHMCS products, restyles the checkout to match and adds a Theme Manager for colors, menus, content and tracking codes.
Square Saved Card Recovery and Gateway for WHMCS
I built this for hosts whose WHMCS lost its saved payment methods while Square still held the cards. It mirrors your Square customers and cards, matches them to WHMCS clients, restores them as pay methods, and includes a Square gateway to charge them.
STACKIT Cloud Server Provisioning for WHMCS
I built this module to resell STACKIT cloud servers through WHMCS. The order form offers flavors, images and volume sizes priced from STACKIT's price list plus your margin, and customers manage power, console and firewall rules themselves.
Strong8K IPTV Panel Module for WHMCS
I built this server module and admin addon to sell Strong8K subscriptions from WHMCS. Paid orders create the device through your reseller API key, renewals extend it, unpaid services are disabled, and customers find their playlist or portal in the client area.
TaxPilot Tax and Expense Reports for WHMCS
TaxPilot is my WHMCS addon for owners who dread tax time. It reads your invoices to show tax collected by rate, country, client type and product, lets you record expenses and the tax paid on them, and works out what you owe for any period.

I built this partner program for a hosting company that sells through agencies. Referral partners earn on the clients they bring in, managed partners add and look after clients themselves, and commission rates follow four tiers set by each partner's monthly recurring revenue.

I built this module for hosts and freelancers who sell malware removal and hack recovery. Each order becomes a case with an encrypted access form, a cleanup checklist, an issue log with severity, report files and messages, all inside the WHMCS client area.
AI Agent Module for WHMCS
A module I build to order: an AI agent inside WHMCS for staff and signed-in clients. It answers from your WHMCS data, prepares actions through the WHMCS API, and waits for an admin to approve anything that changes data. It runs on your own OpenAI or Anthropic API key.
Product Bundles and Packs Module for WHMCS
I built this module to sell products and services you already offer in WHMCS together as one pack at a bundle price. Every item is set up automatically, customers see the pack as one bundle in their client area, and they can move up or down between packs.
Social Login Module for WHMCS
A module I build to order: sign-in buttons for Google, Facebook, Apple, Microsoft and GitHub on your WHMCS login page. A provider sign-in opens the client account whose email the provider has verified, and you set up each provider in the admin area.

A module I build to order: you or your client split a large unpaid WHMCS invoice into 2 to 12 installments, weekly, every two weeks or monthly. Each installment is its own invoice linked to the original, missed ones follow your suspension rules, and clients see the whole plan.

A module I build to order for hosts that sell under more than one name. Each brand gets its own domain, logo, colors, invoice company details, email sender and footer, and its own visible products, while clients, billing and staff stay in one WHMCS.
Order Fraud Rules and Risk Scoring Module for WHMCS
A fraud rules module I build to order for WHMCS. Each new order is scored on rules you weight: disposable email, country mismatch, proxy or VPN, order velocity and risky products. The score decides whether it is accepted, held or canceled, and staff see why.
Uptime Monitor and Status Page for WHMCS
A module I build to order: HTTP, ping and port checks on your servers and services at intervals you set, run from the WHMCS server. Repeated failures open a WHMCS Network Issue and email your staff, recovery resolves it, and clients see a status page and a banner.

An addon I build to order for WHMCS. You write rules such as paid over $1,000 and a client for two years goes to Loyal, put them in order, and the daily cron moves each client into the group of the first rule they match, with a preview first and a log of every move.
Bank Transfer with Proof of Payment Upload for WHMCS
A gateway module I build to order: it shows your bank details on the invoice like the WHMCS Bank Transfer option, and adds an upload form for the transfer receipt. Staff review uploads in one list, then record the payment or send it back with a reason.
Client Service Notes and Account Flags for WHMCS
A staff tool I build to order for WHMCS. Define flags with a name and a color, then add them to clients and to single services with a note, who set them and an optional end date. Flags show as badges across the admin area, never to clients, and a list finds every flagged account.
Colocation Billing Module for WHMCS
A billing module I build to order for data centers that sell colocation through WHMCS. It sets up rack units, power, cross-connects and IP blocks as configurable options, holds each service to a minimum term with an early exit fee, and bills power overage from your monthly readings.
Conditional Order Fields for WHMCS
An addon I build to order for WHMCS. Add rules to product custom fields, such as show Current host only when Migrate my site is ticked, and the order form shows, hides and requires each field to match. Rules are checked again on the server, and hidden answers are dropped.

A watchdog I build to order for WHMCS. Checks that run outside the WHMCS cron alert you, through their own SMTP account or a webhook, when the cron stops, daily tasks do not finish, campaign emails pile up in the queue or WHMCS stops sending mail.

A small addon I build to order for WHMCS. When a service suspended for an overdue invoice is paid and unsuspended, it raises the reactivation fee you set for that product group and currency, on its own invoice or the client's next one, and logs every fee.
