I Built a POS App for Businesses That Still Use Notebooks and Excel. Looking for Feedback.
After months of work, KasirCepat is finally available on Android, Windows, and Linux.
KasirCepat is a simple POS app built for small businesses in Indonesia.
The original goal was surprisingly small:
Help store owners record sales and manage inventory without needing spreadsheets or complicated software.
What surprised me during development wasn't the coding.
It was discovering how many small businesses still rely on notebooks, calculators, or Excel files for daily operations.
A few things I learned while building it:
- Simplicity is harder than adding features.
- Most users care more about reliability than innovation.
- Offline support matters much more than I initially expected.
- Cross-platform development with Flutter allowed me to target Android, Windows, and Linux from a single codebase.
Current features:
✅ Sales transactions
✅ Product management
✅ Inventory tracking
✅ Sales reports
✅ Offline usage

One thing I'm still trying to figure out:
For a POS product targeting small businesses, what feature creates the biggest long-term retention?
Inventory management?
Customer management?
Accounting integration?
Something else?
I'd love honest feedback from other founders and builders.
The Indonesia/small-business angle is good because the job is concrete. I’m seeing the same with Kinetic Override: broad “Android automation” wording is weak, but exact workflow language works — repeated taps, swipe sequences, local no-root profiles, no ads. I’d keep your copy very close to the daily notebook-to-phone moment.
Honestly, I'd be careful treating this as a feature question too early.
I've seen products add inventory tools, CRM features, accounting integrations, and still struggle with retention because the thing keeping customers around wasn't actually the feature set.
What I'd want confidence in first is what makes a business feel uncomfortable going back to its old workflow.
That's usually a stronger retention signal than any individual feature.
Hard to know that from the current stage though.
