Built around the counter
A bill at a busy counter has to take seconds. We design the screens a cashier or a godown clerk uses every hour first, and the reports second.
OthTech Invoice & Inventory is made by OthTech Solutions, a small software company founded in 2025 in Hajipur, Bihar.
We build it for the kirana owner, the distributor with two godowns and the trader whose CA asks for GSTR-1 every month.

4 OthTech products, one team
Most small businesses we meet keep their records in three places. Bills are written by hand or typed into a basic invoice tool. Stock lives in an Excel sheet that someone updates on Sunday. And at month end the CA calls, asking for sales by GST rate and the GSTINs of B2B customers.
None of that is hard on its own. It goes wrong because the same sale is entered three times, by different people, on different days. A missed credit note or a wrong state code shows up weeks later as a mismatch in GSTR-1.
So we built one place for it. You bill once, and that bill moves the stock, records what the customer owes and adds to the GST return. It runs in the browser, so the counter, the godown and the owner at home all see the same numbers.
Six things that decide how the product is built and how we deal with the people who use it.
A bill at a busy counter has to take seconds. We design the screens a cashier or a godown clerk uses every hour first, and the reports second.
Tax split by place of supply, checked GSTINs and HSN codes, returns built from the same invoices. When a rule is unclear, we point you to your CA instead of guessing.
It runs in a browser on the office PC, a counter tablet or the owner's phone. No server in the back room, no new hardware to buy.
The software does not generate e-way bills yet, and the Tally import brings across masters, not old vouchers. We would rather you know that before you sign up.
Plans are listed in INR with their limits. You can see what you will pay for your number of users and branches without a sales call.
Email or call us and you reach the people who build the product. The number on this site, +91 80510 50032, is a real phone.
Switching billing software is a big decision for a small business. These are the things that would make us hard to trust, so we don't do them.
The same team builds software for businesses, schools and people setting up a new computer. Each one gets the same care: plain screens, clear pricing and support from the people who wrote it.
We work with businesses all over India, mostly on calls and WhatsApp. If you are near Hajipur or Patna, you are welcome to drop by. Call ahead so someone is free to sit with you.
