I need a lean, production-ready MVP that lets merchants automatically import daily transactions, apply a 2 % discount to cash and debit payments (none on credit cards), and see the results in real time. Here is the exact flow I want you to implement: – Import: pull sales data either through the POS API or a simple CSV upload. – Classification: flag each line as cash, debit, or credit so the right rule can run. – Discount engine: cash and debit entries receive an automated 2 % rebate; credit remains untouched. – Merchant dashboard (React preferred): totals by payment type, overall revenue, and the dollar value saved through the rebate. – Reporting: generate a monthly PDF that can be downloaded at any time. – Billing: charge the store 0.33 % of its monthly revenue through Stripe, fully automated. Tech stack I’m comfortable reviewing: Node.js or Python for the back-end, PostgreSQL for the data layer, React for the front-end, and the official Stripe SDK for billing. Scope & timeline This is a strict MVP targeted for release in 20 days. The ceiling for the build is CAD 2,000, so please stay within that limit while carving out milestones. When you reply, include 1. A link or brief summary of a SaaS product you have already shipped that shows relevant automation or payment work. 2. Your estimated calendar days to deliver everything listed above. 3. Your all-in cost for those days. I’m ready to move quickly once I see a confident plan that ticks every box.
