The interface that doesn't change

~6 million users, ~600,000 organisations, ~60 million invoices each month. The Swiss QR-bill is the most stable interface in payments.

Stablecoins can be registered as an "alternative procedure" within the QR-bill standard — first unofficially, then officially. The data structure already supports it.

From QR invoice to Bexio — via Solana

A Swiss payment standard file goes in, a Solana transaction comes out, and a Swiss accounting import comes back.

01

Invoice → pain.001

Creditor creates a Swiss QR-bill. The structured payment data encodes as a standard pain.001 payment order.

02

pain.001 → Solana

Debtor uploads the pain.001 to isofix. IBAN resolves to a Solana address via SNS. Stablecoins sent with QR reference memo.

03

Solana → camt.054

Creditor connects wallet, generates camt.054, imports into Bexio. Auto-match via QR reference. Done.
