WHMCS Modules and Themes I Built
11 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.
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.
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.
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.
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.
bexio Sync for WHMCS
A bexio integration I build to order for Swiss WHMCS sellers. Clients become bexio contacts, invoices and WHMCS 9 credit notes are created and issued in bexio with Swiss VAT codes, the bexio PDF with its QR-bill goes out in the WHMCS email, and payments come back.
Canada and Australia Business Tax IDs for WHMCS
A small tax addon I build to order for WHMCS. It adds Canadian GST/HST and QST number fields and the Australian ABN, checks ABNs against the Australian Business Register, marks registered business clients tax exempt where the rules allow and prints your own registration numbers on invoices.
France E-Invoicing and E-Reporting for WHMCS
An e-invoicing connector I build to order for WHMCS sellers established in France. It sends each published invoice and WHMCS 9 credit note to your approved platform in the EN 16931 format it needs, reports consumer and foreign sales for e-reporting, and writes the platform's status back to WHMCS.
Lexware Office Sync for WHMCS
A Lexware Office integration I build to order for WHMCS. Clients become Lexware contacts, finalized invoices and WHMCS 9 credit notes become Lexware vouchers with the right tax type, and payments recorded in Lexware mark the WHMCS invoice paid.
sevDesk Sync for WHMCS
A sevDesk integration I build to order for WHMCS. WHMCS clients become sevDesk contacts, finalized invoices and WHMCS 9 credit notes are created in sevDesk with the right tax rule, and payments flow back so both systems show the same open items.
Sales Tax Automation with Stripe Tax for WHMCS
A tax module I build to order for WHMCS. It asks Stripe Tax for the rate on each cart and invoice from the client's address and the product's tax code, records the transaction when the invoice is paid, reverses it on refund and falls back to your WHMCS tax rules if the service is down.
XRechnung and ZUGFeRD E-Invoicing for WHMCS
An e-invoicing addon I build to order for WHMCS sellers in Germany. It turns WHMCS invoices and WHMCS 9 credit notes for German business clients into XRechnung XML or ZUGFeRD PDFs, validates each file, archives the original and keeps PDF invoices for consumers.
