Use a spreadsheet for low-volume visibility
A well-owned sheet can list PO number, supplier, requested date, latest note, and owner. It may be the right answer for a handful of orders when one buyer controls updates and historical attribution is not critical.
Recognize the collaboration failure point
The model weakens when several buyers edit the same row, supplier replies are copied from email, previous dates are overwritten, reminders depend on memory, and teams cannot distinguish supplier delay from internal decision backlog.
Use software for events and authority
Pacteva records delivery, view, response, proposal, decision, and reminder events. Supplier access is order-scoped, buyer roles are authenticated, and the current commitment is derived from explicit dispositions instead of the most recent cell edit.
Migrate incrementally
Keep the ERP export as the source, import active orders, validate supplier contacts, and run Pacteva for acknowledgment. Continue exporting commitments into the planning sheet until users trust the new queue, then remove only the columns the product now owns.
Validate the workflow with one real purchase order
Before buying or replacing software, run one representative multi-line PO from reviewed source through supplier response and buyer resolution. Include at least one accepted line, one proposed date or quantity change, and one delivery or reminder edge case. Confirm that every participant can identify the current owner and next action, that the original order remains unchanged, and that the final commitment can be exported and traced to its response and decision. Also verify the supplier experience on a normal phone and desktop browser, revoke and reissue a response link, inspect a failed delivery, and test the role boundary with a non-owner buyer. This evidence is more useful than a feature checklist because it exposes adoption friction, hidden authority, and incomplete system boundaries before the workflow reaches production volume.
Keep source, proposal, decision, and commitment distinct
Pacteva records supplier responses and authorized buyer decisions. It does not silently alter the reviewed purchase order or claim an ERP changed unless a configured write-back is verified. Requisitions, budgets, receipts, invoices, payments, inventory, and shipping remain in their systems of record.
What buyers usually ask
When is a spreadsheet still enough?
When volume, collaboration, supplier change complexity, and audit requirements are all low.
Can Pacteva export back to CSV?
Yes. Current commitments and reports can be exported.
Should we migrate historical closed POs?
Usually begin with active orders and import history only when a defined reporting or audit need justifies it.
