Odoo 18 Sales, Staged Billing & Collections for a Fiberglass Manufacturer

A custom Odoo 18 module covering the manufacturer's order-to-cash flow: order requests, staged billing, company-specific invoices, e-Faktur handling, payment proof, income reporting and a pre-sales follow-up pipeline.

• ✔ Staged (termin) billing per sales order, invoiced directly from Odoo
• ✔ Tax invoice numbers read automatically from uploaded e-Faktur PDFs

Offline-Ready Point of Sale for a Building Supplies Store

A point-of-sale system with an Android tablet cashier app that keeps selling when the connection drops, a Go REST API, and a web admin dashboard.

• ✔ Cashiers keep recording sales offline; transactions sync when the connection returns
• ✔ Products sold in multiple units of measure, organized by category

Fleet & Field Canvassing Tracker

Our internal product for tracking field canvassing trips: offline-first GPS capture on mobile, a durable ingestion pipeline, a live supervisor map, route anomaly detection and Odoo integration.

• ✔ GPS points survive app crashes and dead zones: the phone only discards them after the server confirms storage
• ✔ Supervisors follow active trips live on a map

Cinema Ticketing Platform on Go Microservices

Our internal reference build of a cinema ticketing platform: Go microservices with gRPC and event messaging, seat locking, online payment, e-tickets, and web plus mobile apps.

• ✔ Seats are held atomically during checkout, so two buyers cannot take the same seat
• ✔ Booking, payment and ticketing coordinated as a saga across services
