The flow

Six taps from the drawer
to the bank vault.

Cashier counts. Server signs. Envelope seals. Owner collects. Bank reconciles. The loop closes — every step timestamped, every handover signed.

01
Login · Store + PIN
Clock in.
Store code, cashier name, 4-digit PIN. The login is the shift punch-in — no email, no password manager.
02
Count · 13 denominations
Enter quantities.
Plus / minus steppers — no typing. Running total updates live, but only server.calc_total() counts.
03
Verify · Approval code
Server signs off.
The client total is thrown away. Server recalculates, issues CS-20260418-AB3K, binds it to the shift. No edits after.
04
Seal · QR + PIN
Receipt prints.
Bluetooth printer spits a receipt with the QR, the total, and a one-time HANDOVER PIN. Both into the envelope.
05
Collect · Scan + PIN
Owner takes it.
Owner scans the envelope's QR next morning, enters the PIN. Status flips to collected_by_owner.
06
Bank · Reference match
Loop closed.
Owner taps the deposit reference at the bank. Envelope is now deposit_confirmed. Accountant verifies via QR — no login.
The proof

Every shift ends with a receipt.

Not a spreadsheet row. Not a paper envelope. A signed, verifiable receipt — printed on site, searchable forever, auditable by anyone who scans the QR.

Server-signed, not client-trusted

The phone never decides the total. The server recalculates from raw denomination counts and issues the code. Tamper-proof by design.

QR on the envelope, forever

The approval code lives on the printed receipt and as a QR on the envelope. Any accountant with a phone can verify — no CashProof login needed.

Handover signed, every hop

Cashier → safe → owner → bank. Each step flips a state machine. One-time PINs for collection. Deposit reference closes the loop.

Audit-ready exports

Every shift, envelope, and handover in one ledger. Download PDF receipts, CSV reports, JSON data. Your accountant will love you.

Pricing

Less than a coffee.
