The Challenge

The client had operated for years without inventory tracking. They could not reliably answer three questions: how much stock belongs to each merchant, how much has been delivered versus what is outstanding, and which state or branch holds what.

The Solution

We engineered an append-only inventory ledger where every stock movement — stock in, transfer, dispatch, and adjustment — is a recorded transaction and current balances are always derived from them. That design makes the system recoverable: nothing is silently overwritten, and any discrepancy is corrected with an auditable compensating entry.

Per-Merchant, Per-Location Balances

Real-time stock visibility by merchant, SKU, and branch or state.

Append-Only Ledger

Every change is a transaction, so history is auditable and recoverable.

Batch Spreadsheet Onboarding

Import a merchant's full product list with prices, quantities, and categories in one upload.

Orders & Dispatch Agents

Capture local orders, assign errand agents, and track pick-up, delivery, and returns to local.

Periodic Stock & Valuation Reports

Weekly to yearly reports of received, delivered, and remaining stock, by merchant, exportable to CSV or Excel.

Role-Based Access Control

Admin, branch staff, viewers, and dispatch agents each see exactly one clear screen and one job.

Delivery Highlights

  • 46/46 automated backend tests passing at handover
  • Low-disruption rollout — runs in parallel with existing manual process, branch by branch
  • Field stock-taking and reconciliation built in, with variance flagged for approval
