# Bill One vs invox (invox受取請求書): which should you choose?

> Both receive supplier invoices and turn them into data, and both hold JIIMA certification, so the choice is mostly about how you want to buy. invox is transparent and incremental: ¥980/mo to start, a per-invoice charge you can multiply out yourself, and no initial fee. Bill One is a managed, annual commitment with no published price, built for companies whose invoices arrive in every format and who want Sansan to handle the paper. If you can state your monthly invoice volume, price invox first; if paper handling is the pain, get a Bill One quote to compare against it.

## When to choose Bill One

Choose Bill One when the problem is volume and variety: many suppliers, many formats, a lot of it still on paper. Sansan receives paper invoices on your behalf and digitizes them, the service is JIIMA-certified, and users and stored invoices are unlimited — at the cost of an annual contract whose price you only learn from a quote.

## When to choose invox (invox受取請求書)

Choose invox when you want to know the cost before talking to anyone. There is no initial fee, the entry plan is ¥980/mo, and each invoice costs ¥50 with AI OCR or ¥100 with an operator check — so a company receiving a few hundred invoices a month can price the whole thing itself and start the same day.

## Frequently asked questions

### Which is cheaper, Bill One or invox?

It cannot be answered from published data, because Bill One publishes no price. invox's cost is fully published — ¥980, ¥9,800 or ¥29,800 a month plus ¥50 or ¥100 per invoice — so work out the invox figure for your volume and use it as the benchmark when you ask Bill One for a quote.

### Do both check qualified invoice registration numbers?

invox states that it reads registration numbers and cross-checks them against the National Tax Agency's register. The Bill One pages we checked state JIIMA certification but do not describe registration-number checking, so ask Sansan directly if that step matters to you.
