DeskBilling

GST-ready desktop billing software we built for a client, then turned into a product: invoices, credit notes, quotations and unpaid-bill tracking across multiple companies, fully offline.

What We Built

We agreed a reduced build price in exchange for the right to reuse the code, so the client got custom software at a fraction of the usual cost and we got a product. DeskBilling is a Windows desktop app with nine modules: Sales Dashboard, Generate Bills, Billing History, Credit Notes, Unpaid Bills, Products, Customers, Companies and Quotations. It handles several companies from one install, exports to Excel for filing, lets the business customise its invoice layout and stores everything locally. Today it is distributed free with a lifetime licence through our marketplace.

The Challenge

A client needed GST-correct billing without a monthly subscription, an internet dependency or their data sitting on someone else’s cloud. Commercial billing tools were priced for larger businesses, and a fully custom build was more than a small business should have to pay for.

Key Outcomes

  • Client received custom billing software at a reduced price through a code-reuse agreement
  • Nine modules covering the full billing cycle, from quotation to credit note
  • Multi-company invoicing from a single install, with Excel export for GST filing
  • Released as a free product on marketplace.weavelinx.com — no subscription, no cloud lock-in
