# Bill One: pricing and assessment

> Bill One, from Sansan, receives every supplier invoice on a company's behalf — paper by proxy receipt and scanning, PDFs by email — and turns them into data with AI plus human operators, which Sansan states reaches 99.9% accuracy. It is JIIMA-certified as Electronic Bookkeeping Act software. Sansan publishes no prices: there is an initial fee and an annual fee set per customer by invoice volume.

## Strengths and trade-offs

### Strengths

- Proxy receipt of paper invoices: suppliers keep sending paper, and it still arrives in the system as data
- JIIMA-certified as Electronic Bookkeeping Act software, which removes the need to check the retention requirements item by item
- No limits on users or stored invoices, so every department can be given access without a seat count

### Trade-offs

- No price is published at all — neither the initial nor the annual fee — so even a rough budget needs a sales conversation
- Billed annually by invoice volume, which suits steady volumes better than a small company testing the idea month to month
