Three steps. Once.
Setup takes about four minutes. After that, every sale invoices itself.
Connect the store
Paste your Shopify store domain and your invoicing program key. The wizard validates credentials and registers webhooks — no theme changes, no checkout app.
Set the tax rules
VAT included or on top? Default exemption? Dedicated invoice series? All in one panel — no code, no .env files.
Forget it. Every sale becomes an invoice.
Every paid order generates the document in the program you chose, with the customer's VAT ID, the right VAT rate and the legal AT wording. Refunds become credit notes. Automatic.
Built for Portuguese tax rules.
Not translated into them.
Rioko was born in Portugal, for Portuguese stores. Every fiscal detail — from VAT IDs to rounding — is handled the way the tax authority expects.
VAT ID from checkout to document
VAT ID detection in note_attributes, order notes and the billing address, with Portuguese algorithmic validation. Without a valid VAT ID, the document is issued as final consumer.
AT compliance
Issued via certified software, with ATCUD, reported series and the legal wording for M01–M99 exemptions in the invoice notes.
Total equals what was paid
The invoice closes to the cent with what the customer paid on Shopify — shipping, discounts and rounding reconciled line by line.
Double idempotency
Duplicate webhooks, retries and race conditions neutralized: 1 order = 1 invoice, guaranteed by atomic writes + cache.
Simple. Per integration.
The Shopify integration costs the same as any other in the catalog. No per-document fees, no volume limits.

Everything you need to know before connecting your Shopify store. Can't find the answer? Talk to us.
When an order is paid, Shopify sends a webhook to Rioko. Rioko validates the data, detects the VAT ID, calculates VAT and sends everything to your certified invoicing program (InvoiceXpress, Moloni or Vendus), which issues the invoice — usually in under a second.
