Overview
ERP projects connect modules clients actually use — not every checkbox on a brochure.
Problem statement
Purchasing, store, and accounts maintained separate books that never reconciled.
Requirements and constraints
Enable modules per phase: items, suppliers, customers, PO, SO, stock, GL, approvals.
Proposed architecture
Core entities shared; modules register permissions; reports read from transactional tables not duplicated summaries.
Database design
Normalized stock and finance with document numbers and audit on status changes.
API design and authentication
Integrations to POS or external shops via webhooks when needed.
Security
Financial periods locked after close. Role separation on approvals.
Performance
Heavy reports queued; operators keep working on transactions.
Testing and deployment
Month-end close rehearsal with client finance.
Challenges and lessons
Migrating opening balances without breaking trial balance.
Verified results
Leadership reads dashboards fed by live operations, not re-keyed spreadsheets.
