Matching Purchase Orders, Receipts and Supplier Invoices

Identify the documents and their owners

List the documents used to request or approve a purchase, record physical receipt and accept the supplier's charge. State who creates, checks and approves each one. A small business may combine some responsibilities, but the information still describes different events. Ask the provider to show how those events are represented in the proposed setup. Do not assume that a purchasing screen automatically includes every approval or matching process used by a larger organisation.

Start with a complete ordinary purchase

Choose a supplier and a representative product with an agreed quantity and price. Follow the proposed process from the order or purchasing instruction through receipt and invoicing. Compare the item reference, unit, quantity, price and relevant totals. Ask how the records can be found from one another. The receiving team and accounts team should be able to trace the relationship without searching by a similar description or relying on an informal note.

Receive less than was expected

Demonstrate a partial delivery and inspect what remains outstanding under the supported process. Decide how the business handles a later delivery, cancellation or approved substitution. The physical receipt should reflect what actually arrived. If the proposed product does not manage an outstanding order balance, write down the manual control that will be used instead. The business can then judge whether that boundary is practical at its expected purchasing volume.

Investigate price and unit differences

Use a supplier invoice with a deliberate difference from the agreed purchase. Include a unit mismatch if the business buys cartons and tracks pieces. Observe whether the proposed workflow exposes the discrepancy before acceptance and who may approve a change. A price correction should remain understandable to a later reviewer. Have finance approve the treatment of any adjustments, rather than assuming that the software's default entry produces the appropriate accounting result.

Include returns and duplicated paperwork

Process a representative supplier return and inspect the relationship with the original receipt and financial record. Then test how staff recognise a supplier document that has already been entered. Confirm the exact duplicate checks available in the proposed configuration and the procedure where an external reference is absent or inconsistent. A general search facility can assist the operator, but it is not the same as an enforced control against every possible duplicate.

Use an exception review before settlement

Decide how accounts will review unresolved quantity, price or document differences before the relevant settlement step. Keep an owner and supporting evidence for each exception. Ask the implementation team to demonstrate the reports or document views that make this review practical. Combine the result with account mapping tests so the purchasing process and its financial effect are approved together. The acceptance record should identify both supported functions and any deliberate manual duties.
