Hi Product Hunt, I'm Jahirul, a solo Android developer from Bangladesh. I built Mini POS for small shop owners who face two problems every day: the internet drops often, and most billing apps stop working when it does. Many owners still write customer dues in a paper notebook. So I made one rule: everything must work on the phone with no connection. Mini POS doesn't even ask for internet permission. Your data stays on your device, and there are no ads. What it does: - Fast billing with barcode scanning and receipt printing - Stock tracking with low-stock alerts - Customer and supplier dues, ledgers and 9 reports - Several shops in one app, with one-tap backup It's free for 30 days, then a one-time payment. I didn't want shop owners paying a monthly fee for a tool they use every day. I'd love your feedback, especially if you run a shop or build offline-first apps. What should I add next?
