Supplier didn't acknowledge your PO
“It's been two days and I don't know if they even saw the order. No confirmation, no date, nothing.”
You placed a PO. The supplier hasn't confirmed receipt. No acknowledgment email, no confirmed date, no indication they're even aware the order exists. This is one of the most common open loops in procurement — and one of the easiest to let slip until it's too late to recover the schedule.
What triggers this open loop
A PO is placed and the follow-up window you've set in your SOP closes with no supplier acknowledgment.
The acknowledgment window matters because without a confirmation, you have no confirmed delivery date, no confirmation of spec, and no assurance the supplier has capacity. You're operating on assumption.
This situation can also trigger when a PO revision is sent and the supplier doesn't re-acknowledge the updated terms inside that same window.
What's at risk
Unknown lead time — you can't plan production around a date nobody confirmed.
Wrong specification — the supplier may not have seen the latest revision or spec notes.
Capacity issues — the supplier may not have capacity to fulfill the order, but you won't know until you ask.
Schedule slip — every day without acknowledgment is a day of lead time potentially lost. By the time you notice, recovery options may be limited.
No audit trail — if a dispute arises about what was ordered and when, a missing acknowledgment leaves you without documentation.
How most buyers handle it
Most buyers don't have a formal process for tracking acknowledgments. They place the PO and move on to the next task. If they remember, they might check back in a few days. If they don't remember, the missing acknowledgment surfaces weeks later when the delivery is at risk.
The buyers who do track acknowledgments typically use a spreadsheet column or a mental note. The follow-up email — when it happens — is written from scratch, often without referencing the original PO details clearly.
The result: inconsistent follow-up timing, duplicate requests when multiple people are involved, and no record of when the follow-up was sent or what the response was.
How PO-Relay handles it
PO-Relay starts an acknowledgment timer the moment it detects a new PO line item from your ERP, using the follow-up window defined in your SOP. No manual action needed.
When the timer expires without an acknowledgment email from the supplier, the assistant raises an "unacknowledged" flag on that loop. The flag appears in your morning report, on the parts dashboard, and creates a task on your kanban board.
Simultaneously, the assistant drafts an OA (order acknowledgment) request email, pre-loaded with the PO number, line items, quantities, and due dates. The draft includes a concrete response deadline.
If a supplier acknowledgment email arrives at any point, whether before or after your SOP window closes, PO-Relay's email intelligence detects it, classifies it, and either confirms the dates match (clearing the flag) or raises a date mismatch flag if the supplier confirmed different dates.

Common mistakes to avoid
- Letting the follow-up window in your SOP lapse without a chase. Every day of delay is a day of lead time at risk.
- Assuming silence means acceptance. A missing acknowledgment could mean the supplier hasn't seen the order, doesn't have capacity, or disagrees with the terms.
- Not documenting the follow-up. If the supplier later claims they never received the PO, you need a record of when you followed up and what their response was.
- Following up without referencing specific PO details. Vague follow-ups get vague responses. Include PO number, line items, quantities, and expected dates.
