Use an order-centred structure
Create a record for the purchase that links to the approved specification, quotation and relevant product identifiers. Add the batch information when confirmed. Keep document versions clear so later updates are not confused with records used for an earlier decision.
A practical file index
- Order reference and approved product specification.
- Product label or identifier record and applicable batch number.
- Analytical documents with source and report date.
- Receiving observations and relevant shipment references.
- Clarifications, corrected documents and final review outcome.
Preserve a clear change history
If a report is corrected or replaced, record which version is current and why the change was made. Do not silently overwrite a record used for a previous review. Ask the supplier to explain changes to product or batch identifiers.
For repeated purchases, create a new order record even when the product name is unchanged. Link shared specifications without assuming that the batch or delivery circumstances are identical.
Limit access appropriately
Separate publicly shareable product information from private commercial records and customer data. A public report directory should not contain confidential orders or personal details. Use an appropriate access-controlled location for the complete internal purchasing file.
