Al‑Montaser ERP & POS

Overview

Branches, warehouses, accounting and point‑of‑sale in one system: live stock, cash registers and shifts, purchases and returns, tiered tax, customizable invoice layouts.

01The challenge

Branches ran on disconnected systems: stock in one place, the cash drawer in another, accounting in spreadsheets. A simple question — how much of this item is left in the Maadi branch, or was this branch profitable last month — took hours of manual reconciliation, and the answer changed depending on who did the counting.

The commercial rules were not simple either: products with variations and sizes, tiered pricing per customer group, compound tax, credit sales against credit limits, and sale and purchase returns that must move stock and ledger in the same instant.

02What we built

We modelled every financial movement as one transaction type that branches into sale, purchase, return, expense and transfer — each writing its lines into the same ledger. That single decision is what lets the trial balance close: there is no path that changes stock without writing its matching entry.

On top of that: cash registers with per-cashier open/close shifts, live stock per variation per location with lot tracking, expiry dates and rack positions, designable invoice layouts per branch, and ZATCA integration for Saudi e-invoicing.

Then we added the modern layer over that core: a Passport-secured API for the customer app — cart, wallet, instalments, saved cards and support tickets — an OpenAI-backed assistant that answers stock and sales questions in plain language, and WhatsApp notifications for invoices and collection.

03The outcome

Branches are now run from one screen: stock, drawer and ledger all read from the same rows, so the inventory gaps caused by double entry disappeared. Financial reports — trial balance, income statement, account ledgers — are read live instead of assembled at month end.

With the app in place, customers buy, pay in instalments and track orders without visiting a branch, and all of it lands in the same books rather than a parallel system.
