Custom Billing Software & GST Billing App Development

Who develops custom billing and GST invoicing software?
CodeServe Community builds custom billing, GST invoicing, POS and inventory software as web and Android apps for retailers, restaurants, pharmacies, distributors and service businesses. Custom billing apps start from ₹49,999.
Features we can build
Pick only what your business needs. We design the screens so your counter staff can bill quickly with minimal training.
GST billing & invoicing
GST-ready invoices with HSN/SAC codes, tax breakup, quotations, credit notes and your own invoice design.
POS for retail & restaurants
Fast counter billing with barcode scanning, table and KOT management, thermal printer and cash drawer support.
Inventory & stock
Stock updates with every sale and purchase, low-stock alerts, batch and expiry tracking, and purchase orders.
Multi-branch
Manage several shops or warehouses from one login, with stock transfers and branch-wise reports.
Customer ledgers
Credit sales, outstanding balances, payment history and statements for every customer and supplier.
WhatsApp reminders
Send invoices and automatic payment reminders on WhatsApp, so you get paid faster without awkward calls.
Reports
Daily sales, profit, GST summary, top products and staff-wise reports that you can export to Excel for your CA.
Web + Android app
Use it on a computer at the counter and on your phone when you're away, with role-based logins for staff.
Cloud backup
Your data is stored securely on the cloud with automatic backups, so a broken computer doesn't mean lost records.
Custom billing software vs ready-made apps
Ready-made billing apps are a good start for many small shops. Custom software makes sense when your process doesn't fit them. Here is an honest comparison.
Ready-made billing apps
- Low monthly fee, quick to start
- Standard features for common businesses
- You adjust your process to the software
- Limited changes to reports and workflows
- Recurring subscription for every user or branch
Custom billing software
- Built around your exact workflow
- Only the features you need, so it stays simple
- Connects to your website, WhatsApp or other tools
- Reports designed for how you make decisions
- Higher one-time cost, no per-user licence from us

Frequently asked questions
Will the billing software be GST compliant?
We build GST-ready invoices, tax breakups and GST summary reports. Specific requirements like e-invoicing or e-way bills depend on your business and turnover, so we confirm them with you and your CA and build accordingly.
Can I use it without internet?
We can build an offline-capable version for counters that syncs to the cloud when the internet is back. Let us know during planning if your shop has unreliable internet.
Can you move my data from my current software or Excel?
Yes. We import products, customers, suppliers and opening balances from Excel or exports of your current software.
Do I have to pay a monthly fee?
The software is a one-time development cost. You pay for hosting (cloud server) yourself, usually a small monthly amount, and can optionally take a monthly support plan.
Does it work with barcode scanners and thermal printers?
Yes. We support common USB barcode scanners and thermal receipt printers, and A4 invoice printing.
How long does it take to build?
A focused billing and invoicing app usually takes 4–6 weeks. Inventory, POS and multi-branch features add time, which we confirm in the quote.
