Billing Tax and Multi-Currency Setup

This package adds tax and multi-currency support to a custom or Laravel-based billing system, so invoices to customers in the US, Canada, Australia, the UK and the EU show the right tax lines and the right currency, using the rates and rules your accountant gives me. I do not give tax advice: where you must register and collect is your accountant's call, and I make the software apply it consistently.

Two ways to get the rate

Starter uses a rate table you maintain in the admin, keyed by country, state or province, which works when you collect in a few places. Business connects Stripe Tax or a tax API such as Avalara AvaTax or TaxJar, which looks up the rate from the customer's address at invoice time. That matters for US sales tax, where rates change by city and county.

• Canada: GST, HST, PST and QST shown as separate lines when your accountant says they should be.
• EU and UK: VAT ID checks and reverse-charge wording on business invoices, on Business and Premium.
• Exempt customers: certificate upload and an exempt flag, with the reason printed on the invoice.

Currencies and rounding

Prices can be set by hand per currency or converted from a daily exchange-rate source, and the rate used is saved on each invoice. Rounding is a real decision: per line or per invoice gives totals a cent apart, and some currencies have no minor unit at all. I set the rule your accountant prefers and add tests that compare totals with sample invoices they approve.

Who pays for what

Stripe Tax, Avalara or TaxJar fees, and the cost of currency conversion at your gateway, are billed by those providers. Filing returns stays with your accountant; Premium adds an export per jurisdiction that makes their job quicker.
