Overview

What we build for you

Off-the-shelf billing apps work until your business does something they don't expect: batch and expiry tracking, stock across several godowns, special rates for dealers, or credit limits for regular buyers. Then the team falls back to registers and Excel, stock figures stop matching, and outstanding payments are chased from memory.

We build billing and inventory software around how your business actually runs. Invoices carry your GSTIN, the buyer's GSTIN, HSN or SAC codes, place of supply and the right CGST, SGST or IGST split, and they reduce stock the moment they are saved. Purchases, returns and transfers between godowns update stock as soon as they are recorded, and barcode scanning speeds up billing at the counter.

Customer and supplier ledgers show who owes what and since when, and payment reminders go out on WhatsApp with a UPI link. Reports give your accountant sales, purchase and GST summaries, and give you profit and stock value. E-invoicing and e-way bills can be connected as an add-on when you need them.

Ideal for

  • Wholesalers and distributors
  • Retail shops and showrooms
  • Manufacturers tracking raw material and finished goods
  • Pharma, FMCG and electronics traders
  • Multi-branch businesses with several godowns
  • Businesses outgrowing Excel or basic billing apps

FAQ

Questions about the gst billing & inventory software

Can't find your answer? Ask us directly and we'll reply on WhatsApp or by email.

Ask on WhatsApp
Do the invoices include everything a GST invoice needs?
They include the details a GST tax invoice calls for, such as your GSTIN, the buyer's GSTIN for B2B sales, HSN or SAC codes, place of supply, taxable value and the CGST, SGST or IGST breakup. We set up the formats with you, and we suggest your CA reviews them before you go live.
Can you add e-invoicing and e-way bills?
Yes, as an add-on for businesses that need them. We connect the software to an authorised GST Suvidha Provider (GSP), so IRNs, signed QR codes and e-way bills are generated from your invoices. You create the API credentials on the government portal, and the GSP may charge its own fees.
Can it work alongside Tally?
Yes. Many businesses bill and manage stock in one system while their accountant keeps the books in Tally. We can export sales, purchases and payments in a format Tally imports, so nothing has to be entered twice.
Does it work when the internet is down?
The standard version runs in the browser and needs a connection. If your counters have unreliable internet, we can add an offline billing mode that keeps working and syncs invoices and stock once the connection returns.
Can we bring in our existing items and balances?
Yes. We import your item list with HSN codes and GST rates, opening stock by godown, and customer and supplier balances from Excel or your current software's export, so you start with the right figures.
How much does custom billing and inventory software cost?
It comes down to what the software has to handle: how many godowns or branches you run, item details like batches, expiry dates or serial numbers, and integrations such as e-invoicing or an online store. We go through your item types and locations with you, then send a fixed quote to approve before any coding starts.
