Record an Instalment Purchase Without Counting the Full Price Twice

The document problem

purchase invoice and instalment statements

The purchase invoice describes the full price; a payment schedule describes settlement, so adding both produces a misleading total.

Start with the decision you need to explain later, rather than the number of files you can collect. This situation brings together documents with different purposes: one may describe a purchase, another a payment, and another a change to the original arrangement. A useful record preserves those distinctions.

A worked example

Use this document pair as a small working case: purchase invoice and instalment statements.

The key decision is: The purchase invoice describes the full price; a payment schedule describes settlement, so adding both produces a misleading total.

Check source currency: AUD.

Capture the right evidence

Collect the complete receipt or invoice for the actual transaction first. Keep supporting confirmations available as context. A notice or payment statement should not automatically become another expense record. Upload a readable image or PDF through the supported workflow; if several invoices share one file, separate their boundaries before recognition.

Review before using the numbers

Compare the recognised supplier, transaction date, currency, tax where shown, total and line items with the original. The currency printed on a source remains the reference even when a summary uses a selected base currency. Correct a field only when the source supports the correction. Review this case before including it in a period summary.
