## When it happens

A line's `unit_price` has more than 4 significant decimals, typically a price your system computed by division (`total / quantity`) without rounding. It is rejected instead of rounded, so the line's base never differs from what you sent; trailing zeros do not count (`10.500000` is `10.5`). The invoice is not created or changed.

## How to fix it

Round the price to 4 decimals before sending it. If what you know is the line total, send it in `total_excluding_tax` or `total_including_tax` instead, and the unit price is derived from it.

## Retry

Not as is: the same request fails the same way. Fix the cause described above, then send the request again, under a new `Idempotency-Key` if the body changed.
