Apps from ₹50,000 · Fixed quote within 2 hours of the meeting · Serving businesses across India
Quick answer
How much does an inventory and billing app cost in India, and who can build one?
Mana Studio builds it as an Android + iOS app with a web admin panel, with optional AI features, starting from ₹50,000 for a focused first version (stock and GST billing) and ₹1,00,000 for a full product with credit tracking, reorder alerts and multi-user staff access. Book a free 30-minute meeting and you get a fixed quotation within 2 hours of the meeting. The MVP takes 6–8 weeks, the full product 10–12 weeks. Mana Studio is based in Warangal, Telangana, and builds for shops, distributors and wholesalers across India, in English, Telugu and Hindi. Unlike generic billing software, a custom app matches how your shop actually tracks stock and credit, not a template's assumptions.

The manual version of this most shops still run
A handwritten register for credit customers. GST bills made in a generic billing app that doesn't track stock. Nobody notices an item is out of stock until a customer asks for it. Reordering happens from memory, not from actual sales data.
What we build
- Stock tracking by item, batch and quantity, updated on every sale
- GST-compliant billing and invoice generation
- Credit (udhaar) accounts per customer, with due tracking
- Low-stock and reorder alerts
- Sales and stock reports by day, item or customer
- Multiple staff logins with role-based access
Who uses it
A web app / PWA version — usable from a browser, no store install — is also possible if that fits your users better.
- Owner: full reports, stock, credit accounts
- Staff/cashier: billing, stock check, customer credit entry
- Customer (optional): sees their own credit balance
What you own at the end
Full source code, the store accounts in your business's name, and the complete stock and sales database.
AI that removes manual work
AI is optional. These are the add-ons that pay for themselves by taking a repeated manual job off someone's desk.
OCR of paper supplier bills into stock
Today: Staff manually type every item and quantity from a supplier's paper bill into the system.
With automation: A photo of the bill is read and the stock entries are drafted automatically, for staff to confirm.
Reorder point suggestions
Today: Reordering happens from gut feel or when a shelf visibly empties.
With automation: The system suggests reorder quantities based on recent sales speed per item.
WhatsApp bot for stock and price queries
Today: Staff field the same "is this in stock" and "what's the price" calls all day.
With automation: A WhatsApp chatbot answers stock and price questions from live inventory data.

Frequently asked questions
How much does an inventory and billing app cost?
An MVP with stock and GST billing is ₹50,000; the full app with credit tracking and reorder alerts is ₹1,00,000. A fixed quote comes within 2 hours of a free meeting.
How long does it take to build?
6–8 weeks for the MVP, 10–12 weeks for the full product.
Can billing work without internet in the shop?
Yes, billing can be done offline and synced once a connection is back; GST filing exports need a connection.
Does it support Telugu and Hindi?
Yes, the billing screens and reports can be built in English, Telugu and Hindi.
Who owns the sales and customer data?
You do, fully. The database and store accounts are registered in your business's name.
Can you customise ready-made billing software instead of building new?
Only where its API supports real customisation. Most off-the-shelf billing apps don't let you change the credit-tracking logic, which is usually the reason to build custom.
Is there a monthly maintenance cost?
An optional care plan at ₹8,000 per month covers updates and bug fixes; it's not mandatory.
