Weekly digest to suppliers of POs awaiting invoice upload
Description
When a PO is sent to a supplier via ProcurementExpress.com, the supplier is expected to upload the corresponding invoice through the supplier portal. There is currently no automated follow-up if they don't.
Request: Send suppliers a weekly digest email listing all their POs that have no invoice uploaded yet. One email per supplier, aggregating all outstanding POs, with a direct link to upload against each.
Suggested logic:
Trigger: PO sent to supplier + no invoice uploaded after X days
Frequency: Weekly
Recipient: Supplier email on the PO
