Qint invoicing covers the whole loop: draft an invoice with line items, email it to your customer with a Pay now button, let them pay crypto on the hosted invoice page, and have the invoice mark itself Paid the moment the payment settles.

​
The flow

1

Add a customer

Customers → Add customer — name and email are required; company and address enrich the invoice PDF. Customers are archived, never deleted, so old invoices keep their reference.
2

Draft the invoice

Invoices → Create invoice — pick the customer, currency (CHF, EUR or USD), due date, optional memo, and line items. Line amounts are computed server-side (quantity × unit price). Numbers are sequential per merchant (INV-1001, INV-1002, …).
The total always equals the subtotal. Qint’s fee is a conversion spread — it never appears as a line on an invoice or at checkout.
3

Send it

Send moves the invoice from Draft to Open, stamps the issue date, and emails your customer a “Pay now” link (https://checkout.qint.ch/pay/inv_…) with the invoice PDF attached. Sending again while Open re-sends the email.
4

Customer pays on the hosted page

The hosted invoice page shows the line items, due date and your branding, plus the asset grid. Paying works exactly like any other checkout — a 15-minute payment window per attempt. If the customer reopens the emailed link while a payment attempt is still live, the same attempt is resumed rather than stacking a new one.
5

Paid, automatically

When the payment settles (confirmation alone isn’t enough), the invoice flips to Paid, the paid date and payment are recorded, and the customer receives a confirmation email with a receipt. You get the same signal as payment.status webhooks with invoiceId set.

Statuses

StatusMeaningPayable?
DraftBeing edited; fully mutable. Not visible to the customer.No
OpenSent and awaiting payment.Yes
PaidA payment settled against it. Terminal.No
OverdueOpen past its due date (flipped by a background sweep).Yes
VoidCancelled from Draft, Open or Overdue — never from Paid. Terminal.No
The emailed link keeps working after payment: a Paid invoice renders as a paid confirmation (with PDF download) instead of a dead end.

​
PDFs

  • Dashboard: every invoice has a PDF (drafts included, for preview) — inline view or download.
  • Hosted page: customers can download the PDF for Open, Overdue and Paid invoices. Draft and Void invoices are never publicly visible — their public URLs return 404.
  • Paid invoices are watermarked PAID.
