Commercial Desktop ERPRelease candidate
Product overview
- Built for counter and branch staff who cannot depend on continuous internet access.
- Connects sales documents, stock movement and payment records in one local system of record.
- Designed as a product foundation that can sync with a central database when online.
- Release candidate v1.0.0 — feature-complete for its target workflows and under active hardening, not a claim of universal production deployment.
Intended users
- Distributors with branch or counter sales teams
- Retail shops needing fast document entry
- Owners who want auditable stock and cash visibility
- IT staff managing SQL Server on premises or hosted
Business problems addressed
Untrusted stock numbers
Balances in spreadsheets diverge from what the warehouse can actually dispatch.
Slow end-of-day reconciliation
Payments and returns are reconstructed manually after the shift.
Core capabilities
Sales and returns documents
Quotations, invoices and returns with immediate stock impact.
Multi-warehouse inventory
Receipts, transfers and adjustments with movement history.
Treasury recording
Customer and supplier payments linked to open balances.

- Per-branch or per-counter installation models
- Documented backup expectations for local databases
- Versioned release packages with migration scripts
Known scope boundaries
- Not a full statutory accounting suite unless separately scoped
- No implied multi-country tax compliance out of the box
- Mobile and web portals are separate product paths
- Third-party ERP resale is outside CMDS scope
