Growbz builds custom business software for Indian SMEs from ₹75,000: billing and GST invoicing, inventory, quotation workflows and job tracking, in PHP and MySQL, deployable on ordinary hosting with no per-user fees. We eat this cooking: the invoice generator, quotation builder, credential vault and campaign platform that run our own agency are systems we built for ourselves first, and they are the honest answer to “show me something you made”.
What we build
One system instead of three registers.
Billing and GST invoicing
Numbered invoices, PDF output, payment tracking, GST fields done right, like the one that bills our own clients.
Inventory and orders
Stock, purchase, sale and reorder levels in one place instead of three registers.
Quotations and job tracking
From enquiry to quote to job card to bill, with nothing living only in someone's memory.
Multi-user with roles
Staff see what their role needs; the owner sees everything. Every action logged.
How a project runs
Scoped from how the work happens today.
-
01
Watch the real process
We scope by walking through how the work happens today (the notebook, the Excel, the WhatsApp group), not from an imagined ideal.
-
02
Spec and fixed price
Screens, rules and reports on paper, priced fixed, before a line of code.
-
03
Weekly working builds
Your staff try real screens with real data early, because their objections are cheaper in week 3 than week 13.
-
04
Run in parallel, then switch
The old register and the new system run side by side until the numbers match. Then you switch with confidence.
Who this is for
Owner-run businesses drowning in Excel.
Distributors, manufacturers, service firms, agencies. The tell is a daily ritual: retyping the same data into a second place, or a month-end that takes three days of reconciliation. Off-the-shelf tools charge per user forever and still don't fit; custom fits, and you own it.
Results you can verify
Our portfolio for this service is the software this agency runs on, built by us: client and invoice management with PDF billing, a quotation system, an encrypted credential vault, and the email campaign platform whose output you can see in our case study workflows. Need the tool to live inside a customer-facing site? That is web application development: same stack, same team.
What it costs
Fixed price against a written spec.
Single-module tool (billing alone, inventory alone)
₹75,000 – ₹1,50,000
Integrated system (billing + inventory + quotes + roles)
₹1,50,000 – ₹5,00,000
What moves the number: modules, user roles, report complexity, data migration from your current files, and integrations (Tally export, SMS, WhatsApp). Compare honestly against SaaS: a ₹1.5L build that replaces ₹4,000/month of per-user subscriptions pays for itself in three years and then costs nothing but hosting.

Details and pricingStart with the scope, not the spend.
A written spec and a fixed price cost you one conversation. Bring the messy spreadsheet; that is usually where the story is.
