This is my own product — I'm posting it in #showdev because this is exactly the community whose feedback I trust.</p> <h2> The problem I kept seeing </h2> <p>Small shops run on three systems at once: a notebook for stock, a calculator for the till, and memory for everything else. When the notebook and the shelf disagree, the owner loses money quietly, every day.</p> <p>Cloud POS tools fix this, but they charge per month, per register — forever. For a small shop, that rent adds up to more than the software is worth.</p> <h2> What I built </h2> <p><strong>StockFlow POS</strong> — a complete point-of-sale and inventory system that a shop owns outright:</p> <ul> <li> <strong>Checkout</strong> — fast billing with barcode scanning and a cart built for queues</li> <li> <strong>Live inventory</strong> — stock updates the moment a sale happens; low-stock items surface before they run out</li> <li> <strong>Invoices &amp; suppliers</strong> — purchase orders and supplier records in the same place as sales</li> <li> <strong>Staff roles</strong> — separate admin and staff logins, so the till and the settings aren't the same door</li> <li> <strong>Daily reports</strong> — the day's sales picture at a glance, no spreadsheet export ritual</li> </ul> <p>It's self-hosted with the full source code included: one payment, no subscription, no per-register fees.</p> <h2> Try it (30 seconds) </h2> <p>Live demo: <a href="https://stockflowpos-sagit.netlify.app/" rel="noopener noreferrer">https://stockflowpos-sagit.netlify.app/</a><br> Login: <code>admin@stockflowpos.local</code> / <code>admin123</code> (a staff login, <code>staff@stockflowpos.local</code> / <code>staff123</code>, shows the restricted view)</p> <p>If you want to run it for your own shop: <a href="https://shihabtemplates.gumroad.com/l/dwbvk" rel="noopener noreferrer">https://shihabtemplates.gumroad.com/l/dwbvk</a></p> <h2> What I'd love feedback on </h2> <ul> <li>If you run (or have built for) a small shop: which module decides it for you — checkout speed, stock accuracy, or reporting?</li> <li>What's the one feature a POS must never get wrong?</li> </ul> <p>Brutal honesty welcome. That's what showdev is for.</p> showdev webdev javascript productivity
