Custom Billing Software That Replaces Manual Spreadsheets
From GST invoicing and customer credit ledgers to payment tracking and role-based staff permissions, we build business software around your exact workflow.
Built for startups, local businesses and growth-focused teams
Is This the Challenge You Are Facing?
Trapped in Generic Off-The-Shelf Software
Tools like Tally or standard SaaS charge recurring per-user fees while forcing rigid invoice formats that don't match your workflow.
Untracked Credit Dues & Overdue Invoices
Tracking outstanding customer balances across Excel sheets leads to forgotten debts, delayed cash flow, and lost revenue.
Staff Access Without Security Controls
Cashiers and billing clerks can view supplier purchase costs, margins, and delete past bills without management knowledge.
Manual GST & Tax Reconciliations
Accountants spend days calculating CGST/SGST/IGST breakdowns, creating stressful delays during monthly return filings.
Scattered Invoices Across WhatsApp & Paper
Orders taken over phone calls and WhatsApp are not linked to stock counts, causing duplicate shipments and billing discrepancies.
What We Build in Custom Billing Software
Clear deliverables tailored to your exact invoicing operations.
Invoice Management & PDF Sharing
Create, print, download, and automatically WhatsApp professional GST-compliant invoices with pre-printed terms and signatures.

Solution: We engineered a centralized role-based web billing portal with strict customer credit limit controls, automatic WhatsApp PDF invoice sharing with dynamic UPI QR codes, and restricted permissions for billing clerks.

Frequently Asked Questions
Clear answers to genuine buying questions before building custom billing software.
Why choose custom billing software over generic SaaS tools like Tally or Vyapar? ▼
Generic off-the-shelf software forces your business to adapt to their rigid templates and charges hefty recurring monthly user fees. With custom billing software from Bharat Tech Hub, the workflow is built 100% around your exact operations—custom invoice templates, specific dealer credit limits, automated WhatsApp dispatch, and zero per-user licensing fees.
Can the software restrict employees from seeing profit margins or deleting past invoices? ▼
Yes. Granular role-based permissions are built into the core architecture. You can restrict cashiers to only creating new bills while hiding supplier purchase prices, profit margins, and preventing invoice deletion without manager approval.
How does the system handle GST tax calculations and HSN codes? ▼
The software automatically calculates CGST, SGST, and IGST based on the customer's state and automatically assigns HSN codes to items. You can generate monthly GSTR-1 and GSTR-3B export summaries with a single click.
Can our customers pay directly via UPI QR codes on the invoice? ▼
Yes. Every generated invoice and WhatsApp PDF includes a dynamic UPI QR code pre-filled with the exact invoice amount. When scanned with GPay, PhonePe, or Paytm, the payment registers directly in your merchant bank account.
Can the billing software work across multiple branch locations in real-time? ▼
Yes. We build cloud-connected web applications allowing your central office to view real-time sales, inventory, and pending collections across all store branches or warehouses on a unified executive dashboard.
Who owns the source code and financial data? ▼
You retain 100% full intellectual property ownership of the source code and complete control of your financial database. We deploy directly to your secure cloud server or local infrastructure with zero vendor lock-in.
Can existing customer and product data from Excel or Tally be migrated? ▼
Yes. We provide automated data migration scripts that import your historical customer master lists, product catalogs, opening stock balances, and outstanding dues directly from Excel spreadsheets or CSV exports.
What ongoing support and training do you provide after launch? ▼
Every project includes hands-on staff training, video tutorials, and a 30-day post-launch warranty covering bug fixes and minor adjustments, with optional ongoing maintenance retainers for continuous improvements.
