ERP Approvals: From Days to Hours at ANC

Problem

Invoice approvals were entirely manual — accounts payable and receivable were processed by hand, and multi-level signoffs happened over email and chat. The result: slow turnaround and a poor audit trail.

Approach

1. 01

   Built the AP/AR module of ANCoraPRO with hierarchical approval chains modeled per organization level.

2. 02

   Automated email notifications at each approval step so approvers act without being chased.

3. 03

   Designed the PostgreSQL data model for invoices and approvals, keeping a complete history of every decision.

4. 04

   Deployed on Google Cloud behind Nginx for production use.

Outcome

Invoice approval turnaround was reduced from days to hours, with a full audit trail of who approved what and when.
