I’m kicking off a step-by-step build of a full ERP suite, starting with a lean POS prototype. For this first milestone I only need the sales-transaction module, yet it has to be coded cleanly enough to expand later into inventory, CRM and accounting. Scope of this prototype • Process sales by cash and online payment methods • Provide daily cash register reports, live cash-drawer management and an accurate end-of-day balance summary • Include a simple interface (web or desktop is fine), a lightweight database and concise setup documentation so I can demo it quickly I’m happy to hear your preferred stack—whether that’s Python/Django, Node/Express, Laravel, or something else—as long as the code is modular and well-commented for future ERP layers. Compensation model Budget is tight for the prototype, so I will pay a modest fixed fee now and, once the finished system goes live, share a negotiated percentage of profits. If you’re comfortable growing with the project, let’s talk timelines, the specific deliverables you’ll hand over at this stage, and what “ready to extend” means in your architecture.
