Custom POS & ERP Systems, Built for Sri Lankan Business
BATSTACK builds custom POS and ERP systems for Sri Lankan retailers, supermarkets, logistics companies, and SMEs. Offline-first billing that never stops at the counter, real-time inventory across branches, integration with the hardware and payment gateways you already use — and a local team in Gampaha that answers in Sinhala and English. You own the system; no endless foreign subscriptions.
The problems with off-the-shelf software
Off-the-shelf software that crashes
Generic foreign POS tools break under local workflows — multi-branch stock, credit customers, and peak-hour billing. When it freezes at the counter, you lose sales.
No real local technical support
Overseas vendors are a time zone and a support ticket away. When something breaks on a Poya-day rush, you need someone who answers — in Sinhala or English, today.
High recurring subscription fees
Per-terminal, per-month SaaS fees in USD bleed your margin every year and you never own anything. A one-time custom build ends the rent.
Solutions tailored to how you actually operate
Custom billing modules
Invoicing built around how you actually sell — wholesale vs retail pricing, credit/khata customers, returns, discounts, GRN, and tax-ready receipts.
Offline-first synchronization
Bill without internet. Transactions queue locally and sync automatically the moment you reconnect — no lost sales when the line drops.
Hardware integration
Works with your thermal printers, barcode scanners, cash drawers, and weighing scales — no proprietary hardware lock-in.
Inventory & stock control
Real-time stock across branches, low-stock alerts, batch/expiry tracking, and supplier management built for supermarkets and distributors.
Local payment gateways
Native support for PayHere, DirectPay, Genie, and bank IPGs (Sampath, Commercial, HNB) so you collect card and mobile payments the way Sri Lankans pay.
ERP that scales up
Grow from a single POS to full ERP — purchasing, accounts, HR/payroll, and multi-branch reporting on one system, not five disconnected tools.
Technology & reliability you can trust
Cloud-hosted, high uptime
Hosted on reliable cloud infrastructure with automated backups and monitoring — your data is safe, and reports are available anywhere.
Bilingual interfaces
Full English and Sinhala interfaces so every cashier and manager is comfortable — no language barrier at the counter.
Dedicated SLA support
A defined service-level agreement with response-time commitments, updates, and a local team that actually picks up the phone.
Built for Sri Lankan business
Designed for local retail, F&B, pharmacy, hardware, and logistics operations — the workflows you use every day, not a foreign template.
Engagement models
Every build is a one-time investment — you own the system. Final scope and LKR pricing are confirmed after a free requirements call.

Frequently asked questions
How much does a custom POS system cost in Sri Lanka?
A custom POS is a one-time investment scoped to your business — number of terminals, branches, and modules — instead of a recurring per-terminal foreign subscription. BATSTACK gives a fixed LKR quote after a free requirements discussion, so you own the system outright with no monthly rent.
Will the POS work without internet?
Yes. BATSTACK POS systems are offline-first: billing, printing, and stock updates keep working with no internet, and every transaction syncs automatically to the cloud the moment your connection returns. You never lose a sale during an outage.
Does it integrate with PayHere and local payment gateways?
Yes. We integrate PayHere, DirectPay, Genie, and bank IPGs (Sampath, Commercial, HNB and others) so your customers can pay by card and mobile wallet, with settlements to your local bank account.
Can it connect to my thermal printer, barcode scanner and cash drawer?
Yes. Our POS integrates with standard thermal receipt printers, barcode scanners, cash drawers, and weighing scales. You can keep the hardware you already own — no proprietary lock-in.
Do you provide support in Sinhala and after the system goes live?
Yes. BATSTACK is a Sri Lankan studio based in Gampaha. You get bilingual (Sinhala/English) support and a defined SLA covering updates, fixes, and training — with a local team that responds, not an overseas ticket queue.
