Mazimo Gold ERP
Gold-weight accounting, melt tracking, a jewellery point of sale and double-entry books in one installable web app.
Built for a counter that sells by the gram.
A jeweller’s books run in two currencies at once: money and gold. This system keeps both — an immutable double-entry journal for the dirhams, and a separate gold ledger by karat and purity where negative stock simply can’t happen.
It covers the day from the first sale to the melt: tax invoices, credit notes and proformas with QR codes, a PIN-protected simple mode for counter staff, and a melt cycle with send, receive, loss check and manager approval.
It runs in production for Mazimo Jewellery in Deira, Dubai, in English, Arabic and Persian with full right-to-left layouts — forty-two releases and counting.

Journal rules are enforced by database triggers. Corrections are new entries, never edits.

Stock is tracked in grams per karat and purity, with exact decimal maths — no floating point.
Melt cycle
Send, receive, check the loss and get a manager’s approval before the books move.
Invoices that print
A4 and 80 mm receipts, bilingual English and Arabic, with QR codes and UAE VAT.
Simple mode
A PIN counter view for staff, with roles, teams and two-factor sign-in behind it.
Connected
A signed bridge to the mazimo.ae storefront and a Telegram bot for alerts.
