Hyperlocal FAQ
How much does custom software cost in Gampaha?
Every project is a one-time investment quoted in LKR and scoped to your business — a POS, mobile app, or web app each carry different scope. BATSTACK gives a fixed quote after a free consultation, and you own the source code outright with no recurring foreign subscription.
Can we meet in person in Gampaha, or is everything remote?
Both. BATSTACK is based in Gampaha, so we offer on-site consultations across Gampaha, Yakkala, Kadawatha, Kiribathgoda, Mirigama, Minuwangoda, and the wider Western Province — or online over WhatsApp and Google Meet if that is easier.
Do you provide maintenance and support after launch?
Yes. Every project includes a defined maintenance SLA covering fixes, updates, and OS-version maintenance, with bilingual Sinhala/English support from a local team that actually answers — not an overseas ticket queue.
Do we own the source code?
Yes — 100%. On final payment all source code, IP, and design assets transfer to you in writing. Your software is never locked to us or a third-party platform.
Which payment gateways and hardware do you support?
We integrate PayHere, DirectPay, Genie, and WebXPay, and our POS works with standard thermal printers, barcode scanners, cash drawers, and weighing scales — no proprietary hardware lock-in.
