Athena Xtreme POS & ERP

A multi-branch retail ERP and POS for stores that sell on credit. Cash and installment sales, guarantor tracking, automatic payment allocation, serial-number and barcode traceability, and full back-office: GRN, suppliers, transfers, quotations, returns, expenses, HR and payroll.

Consumer-goods retailers selling on installments track plans, guarantors and collections in books and spreadsheets. Payments get mis-allocated, serial numbers are untraceable, and branches can't see each other's stock.

Branch-isolated multi-tenancy with role-based access (super admin, admin, manager, cashier, viewer), a fast POS with dual-barcode and serial scanning, a flexible installment engine with automatic allocation, cash-up reconciliation, bulk Excel import jobs, PDF invoices and a MongoDB audit trail for every operation.

Live for Chathura CCTV & Scale across three branches — Nivithigala, Kalawana and Baduraliya — with 250+ commits, Playwright end-to-end and Vitest test suites, and bilingual (next-intl) support.
