Warranty and EMI Tracking for Mobile and Electronics Retailers

01.Who this is for

This is for mobile phone and electronics shops that sell devices with warranties and instalment plans and then handle the after-sales questions. You have outgrown files and notebooks when customers come back long after the sale without a bill, staff search old invoices for a serial number, and late instalment payers are chased from memory. Warranty claims move between the shop, the brand and the service centre with no clear status, and the customer blames the shop for every delay.

02.Where retailers get stuck

Warranty details are on a paper bill that the customer lost. Instalment payments are tracked in a notebook, and late payers are chased by memory. Claims move between the shop, the brand and the service centre without a clear status, and the customer blames the shop.

03.What we build

Billing that records serial numbers and warranty periods at the time of sale; an EMI and instalment tracker showing due dates, payments received and overdue accounts; and a claim register that follows each warranty case from the counter to resolution. A customer can be found by phone number in seconds. Invoices carry GST details for your accountant to use.

04.Where AI helps

A warranty-claim bot. On WhatsApp, it can ask the customer for the basic details, check the sale record and warranty period, and prepare the claim for your staff. Your team confirms the claim and handles the brand. Customers get a quick, clear first response.

05.Fewer arguments, more repeat business

When a customer’s purchase, warranty and payments are all one search away, the shop looks organised and trustworthy, and that is what brings people back for their next phone. A realistic first release matters more than a big plan. We would begin with billing with serial and warranty records, build that single slice, put it in front of your staff and fix whatever they stumble on before adding anything else. Brandsmashers Tech is based in Bhopal, so we can sit at your counter in Bhopal or Indore instead of working only over calls. We use AI-assisted development to keep builds fast, and a person on our team reviews every release. Pricing depends on scope, so we quote after we have seen your process, not before. Ask any vendor who owns the data and whether you can export it at any time; we answer both in writing before work starts.

06.How a first version comes together

The first version gets the sale recorded properly, because every later question depends on it.

1. 01We stand at your billing counter to see how serial numbers, warranty terms and instalment details are captured at sale today.
2. 02We agree a first version of billing that records serial numbers and warranty periods, with customers searchable by phone number.
3. 03Counter staff test it on real sales, and we make sure finding a past customer takes seconds, not a search through files.
4. 04The EMI and instalment tracker with due dates, payments and overdue accounts is added next, followed by the claim register.
5. 05The WhatsApp warranty-claim bot comes last, collecting details and preparing claims that your staff confirm before contacting the brand.

07.Questions buyers ask

What should mobile shop billing software in India record at the time of sale?

It should record the serial number, warranty period and customer phone number on every bill. With that captured at sale, a customer who loses the paper bill can still be found in seconds, and the purchase date and warranty status are clear without searching. It also makes warranty checks quicker, because the counter is not guessing dates.

Can it track EMI and instalment payments?

Yes. The instalment tracker shows due dates, payments received and overdue accounts for each customer. That replaces the notebook and memory, so staff know who to contact and when, and the owner can see the total overdue position without asking anyone. Gentle, timely reminders are easier on the customer than a sudden chase.

How does the warranty-claim bot work on WhatsApp?

It asks the customer for basic details, checks the sale record and warranty period, and prepares the claim for your staff. Your team confirms the claim and handles the brand. The customer gets a quick, clear first response, and a person makes every decision. Claims stop getting lost between the shop, the brand and the service centre.

Will invoices work for GST?

Yes. Invoices carry GST details for your accountant to use, so your books stay in their hands. We also answer who owns the data and whether you can export it at any time in writing, before any work starts. That means the customer record stays yours, whatever tools you choose later.
