Every sale gets an invoice. You do not create it or send it; AgentaOS issues it when the payment clears. For a card or bank sale, AgentaOS is the merchant of record, so the invoice names AgentaOS (Aristokrates OÜ, Estonia) as the seller, “Merchant of Record for” your business. The invoice carries the buyer’s details and the tax breakdown for the buyer’s country. You can also create an invoice by hand and email it to a customer. The customer pays it on the same hosted checkout as a product.

The Invoices page

The Invoices page with the All, Open, Paid, and Void tabs and one paid invoice, INV-2026-0001, for 12.40 euros

The Invoices page. The tabs split invoices by status.

In the sidebar, click Invoices. The page has four tabs, each with a count:
  • All: every invoice, newest first.
  • Open: invoices sent and waiting for payment. An open invoice past its due date shows Overdue.
  • Paid: paid invoices for a period you pick, with Revenue, VAT, and Invoices totals at the top. A paid invoice with a chargeback shows Disputed or Charged back.
  • Void: voided invoices, kept for your records.
The How invoicing works link at the top opens this page.

​
When an invoice is issued

A sale from a product’s buyer link gets its invoice when the payment clears. The invoice goes straight to Paid. An invoice you create by hand, or a checkout your server creates, gets its invoice when you create it. That invoice sits in Open until the customer pays, then moves to Paid. When the payment clears, AgentaOS also emails the buyer a receipt. See Receipts.

  • Invoice PDF: the seller and buyer details, the line items, and the tax breakdown (subtotal, tax, total).
  • Statement: on the Paid tab, click Download statement. The PDF covers the period you picked, with the opening and closing figures, every transaction, and a VAT summary by rate.
  • CSV: on the Paid tab, click Export CSV. The file has 23 columns for accounting software, including the invoice number, the tax name, rate, and amount, a total_eur column, and the buyer’s name, company, country, and VAT number.

​
Void an invoice

Voiding marks the invoice as void in your records. It does not refund the buyer or touch the payment. Use it to correct a bookkeeping mistake. Only an owner or an admin can void an invoice. On the Paid tab, click the void icon in the invoice’s row, then click Confirm void. To cancel an open invoice that the customer will not pay, void it through the API (below).
You cannot undo a void. The invoice stays in the Void tab.

​
From code

Every invoice on the Invoices page is also available through the API. The full reference is in Invoices (SDK) and agenta invoices. Amounts on an invoice are in currency units: 19.99 means €19.99.
The status filter takes all, issued, paid, or voided. An invoice’s status is issued (the Open tab), paid, or voided. A list call returns { items, total, hasMore }.
