Nidhi Warranty & AMC is warranty tracking and AMC management software for Indian dealers and service shops, at ₹399/month with unlimited users. Register the cover that came with a sale, bill annual maintenance contracts on the customer's recurring invoice, answer "is this covered?" from a serial in one step, and renew a contract with one button.
If you sell machines, appliances, pumps, inverters or electronics, the questions come back months later: is this one still under warranty, who is on a maintenance contract, and whose contract runs out this month. Nidhi Warranty & AMC keeps that record next to the sales you already bill in Nidhi Books. Cover on a serial-numbered unit is read from the sale — customer, item, serial and sale date — so you only type how many months it runs. A machine sold before you started using Nidhi can be registered by hand. When free cover ends, the AMC you sell next is billed through the customer's recurring invoice, so contract income shows up in the reports you already use. The renewals desk shows what runs out in the next 30 days and what already has. Available on the 399apps cloud or self-hosted.

Register the warranty against a serial-numbered unit you sold, against a bill line for goods without serials, or by hand for a machine sold before you joined. Mark it as manufacturer, dealer or extended cover. The end date is worked out from the start date and the number of months, never typed, so 12 months from 1 January ends on 31 December.
Pick the unit you sold and leave the rest blank. The customer, the item, the serial and the sale date are read from the bill you already raised. You type only how long the cover runs.
Record the maintenance contract — customer, start and end date, fee, and whether it is billed weekly, monthly, quarterly, half-yearly or yearly — and put the fee on that customer's recurring invoice. Each bill is then raised by recurring invoicing in Nidhi Books, so AMC income lands in the reports you already have.
Each contract owns exactly one line on the recurring invoice. Applying it again rewrites that line instead of adding a second. Nothing reaches the customer until you have seen the amount and confirmed it, and if the fee changed after you opened the page, the save is refused.
Type or scan a serial, or pick a customer or an item, and get one answer: covered until a date, not covered today, or cover ran out on a date. Sale warranty and AMC cover are listed together. If you also use Nidhi Job Cards, the warranty on repairs you did shows up in the same list.
One screen with two lists: contracts and sale cover ending in the next 30 days, and those that have already lapsed. Cancelled contracts and contracts already renewed are left off, so the list is only what still needs a phone call.
Renewal starts the next period the day after the old one ends, with the same customer, machines, fee and billing cadence. The fee line moves to the new period instead of being copied. A one-year contract renews into a full calendar year, and the old period and its bills are left untouched.
Customers with an email on file get one renewal email 30 days before their contract ends, with the end date and the fee. It goes once per contract per end date, however often the nightly check runs, and you can switch it off.
Warranty and AMC tracking pays for itself in some businesses and is wasted in others. Read this before you add the app.
You sell things that come back for service
If customers return with a machine and ask "is this still under warranty?", the lookup answers from the serial in one step, instead of someone searching old bills.
AMC income is slipping through
If AMCs are written on paper or raised as a one-off invoice and forgotten, putting the fee on a recurring invoice and working the renewals list every month is how that income keeps coming in.
You run a service desk as well as a counter
With Nidhi Job Cards alongside, the counter and the workshop see the same cover for the same machine, including the warranty on past repairs.
Nothing you sell carries cover
A grocery store, a garment shop or a stationery seller rarely gives warranties or sells AMCs. Nidhi Books alone covers billing at ₹399/month — do not pay for an empty register.
You need technician visit scheduling
This app tracks cover, bills contracts and chases renewals. It does not plan preventive maintenance visits, assign technicians to routes or record site visits. If that is the core of your AMC business, a field-service package such as Zoho FSM will fit you better today.
You want warranty claims filed with the manufacturer
The register records what cover a machine has. Raising and tracking claims with the brand or the manufacturer's portal is not part of it.
Dhyaan dein. Nidhi Warranty & AMC reads the invoices and customers you keep in Nidhi Books, and bills contracts through its recurring invoices, so the two run together — ₹399 + ₹399 = ₹798/month with unlimited users. Serial numbers come from Nidhi Inventory if you track serials there; without it, register cover against a bill line or by hand.
