Ready-made billing app or custom billing software?
India has many good ready-made billing apps, and for a single shop with standard needs they are the right choice: low cost, quick to start, and GST updates are handled for you. We tell clients this honestly.
Custom billing software makes sense when your business doesn’t fit the template — for example:
- You run several branches or warehouses and need stock transfers and branch-wise reports.
- You sell to dealers with different price lists, credit limits and schemes.
- Billing must connect to your website, online store, CRM or production — no double entry.
- You have industry-specific rules: batch and expiry (pharma), weight-based pricing (jewellery, grocery), job work, rentals or subscriptions.
- Per-user subscription fees have become expensive as your team grows.

- Per-user or per-device pricing

Custom software

Frequently asked questions
What is GST billing software?
GST billing software creates tax invoices that follow Indian GST rules — GSTIN, HSN/SAC codes, CGST/SGST or IGST — and keeps records of sales, purchases and stock for filing returns.
How much does custom GST billing software cost in India?
At Kode Studio, custom billing software starts at ₹34,499 for invoicing and reports, and ₹75,000–₹4,00,000+ with inventory, POS, multiple branches and integrations, plus yearly hosting.
Is custom billing software better than Vyapar or Tally?
Not always. Ready-made apps are cheaper and faster for standard needs. Custom software is better when you have unusual workflows, many users or branches, or need billing connected to your website, store or CRM.
Can the software send invoices on WhatsApp?
Yes. Invoices can be shared as PDF links on WhatsApp, with payment reminders and a UPI QR code for instant payment.
Does it support e-invoicing and e-way bills?
Yes, for businesses that need them, we integrate e-invoice (IRN) generation and e-way bills through government-approved providers.
Will it work offline?
Browser-based systems need internet. For counters with unreliable internet we can build an offline-capable POS that syncs when the connection returns.
