Hamer is a manufacturing and export business shipping overseas from Thailand. Export paperwork is a chain: proforma invoice, job order, packing list, commercial invoice, payment. Break one link — or retype one number — and the shipment stalls at a port.
What we built
An ERP where the document chain is the data model. Every downstream document is generated from its upstream one and linked back by shared reference numbers, so the whole order lifecycle is traceable end to end:
- Documents — proforma invoices, job orders, packing lists, commercial invoices, and shipping marks generated as PDFs, complete with carton counts, gross and net weights, dimensions, and CBM for international freight.
- Inventory — bundles and items with attributes, images, stock adjustments, and balance tracking.
- Pricing — customer-specific price sets, per-item price lists, and sold-price history per customer.
- Money — multi-currency documents with exchange rates and Thai baht conversion, plus accounts-receivable tracking against invoices.
- Reporting — styled Excel workbooks for debt, inventory, and pending orders, alongside a live dashboard.
In production
Real orders and real money have moved through this system for years — with change auditing on inputs and a maintenance history that reflects a tool a business actually leans on. We still ship same-day fixes when operations need them.
