Print and signage ERP and billing platform

We built a multi-tenant ERP for print, signage and fabrication businesses that covers everything from quotation to installation.

Sector: Finance & ERP. Platforms: Web, API. Client: kept confidential.

The challenge

Print shops price work by area, follow every job through several production stages and need GST-compliant invoices and accurate customer ledgers.

What we built

The platform includes a square-foot pricing engine with per-line overrides, quotations that convert into auto-numbered invoices, partial payments and printable PDFs.

Customer ledgers are derived automatically from invoices and payments, and job cards follow each order from design through printing, lamination and fabrication to installation.
