Free Installment Software: Manage Payment Plans Without Monthly Fees

Installment selling is how a large share of phones, laptops, appliances and motorbikes are sold in Pakistan. But the tools most shops use to manage it are still a paper register, a notebook of guarantor numbers, and memory. Dedicated installment software usually comes with a monthly fee, which is why many small shops never switch.

This guide explains what installment software should do, and how to run your installment business on software that costs nothing.

What goes wrong with a paper installment register

• No due list. The register shows balances, not who is due today or overdue by two weeks. Recovery calls depend on someone remembering.
• Guarantor details get lost. When a customer stops paying, the guarantor's CNIC and phone number need to be on hand immediately — not on a loose slip.
• Arithmetic errors. Every partial payment means re-calculating the remaining balance by hand.
• Disputes. "I already paid that installment" is hard to settle without a dated payment history.
• One book, one point of failure. If it's damaged or lost, months of records go with it.

What good installment software should do

1. Create the schedule at the point of sale. Product, price, advance payment, number of installments, and weekly or monthly frequency — the schedule is generated automatically.
2. Store guarantor details on the sale. Name, phone and CNIC, printed on the invoice as well.
3. Show a due and overdue list. Sorted, so the first thing you see each morning is who to call.
4. Record payments against the schedule. Partial and early payments applied correctly, with the remaining balance always up to date.
5. Link to the exact item sold. For phones, that means the IMEI — so a returned or disputed unit can be matched to the installment account.
6. Report collections. How much was collected today, by which staff member, and what is still outstanding.

Free installment software: MobiPOS

MobiPOS's installment module does all six — and it's part of a complete POS that is free for lifetime. There is no paid tier to unlock installments, no limit on how many installment customers you can track, and no trial that expires.

Because it is a full POS, your installment sales sit alongside your cash sales, stock, purchases, expenses and profit reports — so you see the whole business, not just the installment book. It works in any browser, including on your phone.

Switching from paper without stopping your shop

Start by recording every new installment sale in the software from day one. Keep the paper register for existing accounts and add them gradually as customers come in to pay. Within a couple of months most active accounts will be in the system, and the paper register becomes a backup rather than your main record.
