<section class="help-summary" aria-labelledby="in-short"><h2 id="in-short">In short</h2><p>Each document carries a currency and several amounts that mean different things. For an invoice, start with total and subtract payments plus allocated credits to get remaining balance. For a credit note, start with issued amount and subtract refunds plus allocations. Never mix currencies in a manual total; analytics separately uses a base currency and historical rates.</p></section>

## Expected result

You reconstruct document remaining amount without combining currencies or different financial notions.

## Before you start

- Display currency next to every compared amount.
- Open allocations rather than assuming a credit note is fully applied.

## Procedure

1. Identify document type and currency.
2. For an invoice, record total, paid, and allocated credits.
3. For a credit note, record total, refunded, allocated, and available amounts.
4. Confirm displayed remainder matches components in the same currency.
5. For multi-currency views, use converted analytics instead of manual addition.

## What Billabex does

Billabex rounds monetary operations and stores movements required for analytics. Analytics conversion uses organization base currency and the historical rate on movement day.

## If the result is not what you expected

- A multi-currency total without conversion has no financial meaning.
- A discrepancy can come from available credit not allocated to the invoice examined.
- If a historical rate is unavailable, analytics fails temporarily rather than returning a partial total.
