When you sell through Macropay, we are the legal seller of record — not just a payment processor sitting between you and a card network. Your customer’s bank statement shows Macropay. The invoice is issued by Macropay. And the obligation to calculate, collect, and remit sales tax / VAT / GST in every jurisdiction you reach belongs to Macropay, not you. That single shift removes the most painful part of monetizing software internationally: you ship product, we own the tax, PCI, and dispute machinery underneath it.
Merchant of Record handles indirect taxes — never your income tax. We collect and remit US Sales Tax, EU VAT, UK VAT, Canadian GST and the like. You remain responsible for income/revenue tax in your own country of residency.

​
PSP or MoR?

The right answer depends on how much of the billing stack you want to own.

​
Payment Service Providers

A PSP — Stripe, Adyen, Checkout.com and peers — gives you a clean abstraction over the card networks and acquiring banks so you can charge a card without operating those relationships yourself. The tradeoff is that everything around the charge stays with you.

​
Merchants of Record

An MoR sits on top of the PSP layer and fulfills the complete digital order, not just the card capture. Macropay routes inbound payments across multiple licensed PSPs and handles the rest in-house — invoicing, tax, refunds, chargebacks, and payouts. Card data is tokenized in our PCI DSS Level 1 compliant vault, so PCI scope never lands on your servers.
Choosing in one line. Take a raw PSP if you already shipped on one, want absolute low-level control, or are optimizing purely for the lowest processing fee — and you’re fine owning tax, invoicing, and disputes. Choose Macropay if you want product, customer, order, and subscription management out of the box, built-in benefits like license keys, file downloads, Discord and private GitHub invites, and someone else to own international tax.

​
Built for usage and agent billing

Being the seller of record isn’t only about classic checkout. Macropay computes the correct tax at checkout regardless of pricing model — fixed, free, pay-what-you-want, seat-based, or usage-based metered billing. That matters most for the newest billing pattern: AI agents that bill by usage, activity, or outcome. Whether an agent is metered on tokens through the OpenAI-compatible AI proxy or charged on a certified outcome via the Signals API, the resulting sale still needs tax handled correctly in the buyer’s country — and as MoR, we do that for you on every transaction your agents generate.

​
How we actually handle the tax

Most MoRs simply tell you “we handle tax globally, don’t worry about it.” We do too — but we’d rather show our work, so you can judge it (and decide whether to do it yourself).

​
What “handling tax” means

Nearly every country, state, and jurisdiction taxes digital goods and services (VAT, GST, US Sales Tax), whether or not the seller is resident there. Compliance is two obligations:
1

Capture

Charge the customer the correct tax-inclusive amount and ring-fence the tax portion separately from your balance. Macropay computes the right rate at checkout and holds captured tax apart from your funds.
2

Remit

File and pay that captured tax to each local authority on time. Macropay owns registration, filing, and remittance in every jurisdiction where we’re the MoR.
Rates, thresholds, and rules differ everywhere. A worked example — a €20/month plan sold into Germany (19% VAT):
  • A consumer pays €23.80/month; €3.80 is ring-fenced for the German tax authority.
  • A VAT-registered business pays €20.00/month — the reverse-charge mechanism shifts the VAT accounting to the buyer.
Some jurisdictions (UK, EU) require registration before your first sale; others (e.g. Texas) don’t until you cross a large threshold — Texas only after $500,000 in sales 🇺🇸🦅. It is genuinely hard: even large companies don’t get it perfect, and many delay compliance as a calculated risk, accepting back-taxes and penalties as a cost of moving fast.

​
The two paths, side by side

​
Macropay’s coverage

We support global payments and take on liability for international indirect taxes everywhere we operate, then expand formal registrations as the data warrants. Current registrations
  1. United States — Macropay Software Inc. is a Delaware C Corp; registers for state Sales Tax as thresholds are reached.
  2. EU VAT — Irish One Stop Shop (OSS).
  3. UK VAT.
No MoR registers everywhere up front — it’s unnecessary under threshold rules and prohibitively expensive with uncertain ROI. We work with global accounting firms who specialize in registration, filing, and remittance, so we can scale coverage on demand.
The economics, transparently. A new market costs us roughly 500∗∗toregister,∗∗ 500** to register, **~300 per (roughly quarterly) filing, plus consultations and our own reporting effort — on the order of 1,700inyearoneand1,700 in year one and 1,200 per year after. In a market with 20% sales tax, standalone tax liability starts to outweigh those costs around **6,000∗∗insales(6,000** in sales (1,200 ÷ 20%). For Macropay, at a ~1.1% premium over a raw PSP, we’d need about **109,090∗∗inthatmarketbeforeourspreadcoverstheaccountingcost(109,090** in that market before our spread covers the accounting cost (1,200 ÷ 1.1%).
Most of our customers sell into the US, UK, and EU, so given US thresholds and our existing registrations this is largely a non-issue. In markets where we aren’t yet registered, we still carry the liability while we assess long-term potential — and we’re comfortable betting on a market well before it’s profitable for us. Where neither holds in the near term, we reserve the right to temporarily block payments from a country until the opportunity changes.
Want to run tax yourself? If you’re selling enough that ongoing compliance costs are worth it, reach out — we’re happy to introduce you to the accounting firms we work with. MoR is a core value-add, not the only reason Macropay exists; our goal is to be the easiest way for developers to monetize, and we’ll salute anyone shipping software regardless of which billing platform they choose.

Frequently Asked Questions

Macropay’s VAT number is EU372061545. This is an EU One Stop Shop (OSS) registration, which lets a non-EU business like Macropay (a Delaware C Corporation) handle VAT for all EU countries through a single registration in Ireland.
OSS VAT numbers use the EU prefix instead of country-specific prefixes (like IE for Ireland). Some accounting software predates the OSS program or lacks support for the format. You can usually enter the number manually if your software allows overriding validation, or ask your vendor to add OSS number support.
