Frequently Asked Questions

What is the standard payment term for approved invoices?
Standard payment terms are Net-60 from the date of goods receipt and invoice approval. Strategic partners with approved credit facilities may qualify for Net-30 terms upon request. Early payment discounts are not currently offered.
How do I update my banking or tax information?
Navigate to Vendor Profile > Payment Settings in the portal. All banking changes require dual verification and may trigger a 5-day compliance review to prevent fraud. Tax documents must be submitted to compliance@aevumzenth.com with a signed cover letter.
Are API integrations supported for real-time PO tracking?
Yes. Vendors can enable the "Order Sync" module in the developer dashboard. Webhooks push real-time PO status updates, and REST endpoints allow bidirectional inventory sync. Rate limits are 1,000 requests/hour per environment.
What happens if an invoice is rejected?
Rejected invoices remain in "Correction Required" status. You will receive an email with specific line-item discrepancies. Resubmit within 14 days to maintain original payment priority. Invoices older than 180 days require manual AP review.
How do I request a dedicated account manager?
Vendors exceeding $2M in annual contract value or operating across 3+ divisions automatically receive a dedicated Aevum Zenth account manager. For others, submit a partnership tier review through the portal under "Commercial Terms."
