Collecting Customer Payments on Time: A Receivables Routine for a Small Business

When you look at your overdue list, the reasons usually fall into a few groups. Some invoices were sent late or went to the wrong person. Some customers were never told clearly when payment was due. Some are waiting on a correction, such as a wrong rate, a missing purchase order number or a short delivery. And a smaller group simply pay whoever chases hardest.

Only the last group needs pressure. The first three need a better process on your side. That is why the routine below starts before the invoice is even raised.

• ✓Agree the payment terms in writing before you deliver: the number of days, the start point, the payment method, and any advance or part payment.
• ✓For a new or large customer, check how they have paid other suppliers where you can, and consider starting with a smaller credit limit or an advance.
• ✓Set a credit limit for each regular customer, the most you are willing to have outstanding with them at any time.
• ✓Find out who approves and releases payments at the customer's end, and what they need on the invoice, such as a purchase order number or a delivery challan reference.
• ✓If you are registered under Udyam, tell your customers and mention it on your quotations and invoices, so the buyer knows the supplier's status from the start.

Clear terms are also the basis for any later claim: written terms on the contract and the invoice show exactly when payment was due.

1. 01

   Invoice on the day of delivery

   Every day between delivery and invoice is a day added to your collection time. Raise the invoice when the goods leave or the service milestone is completed, not at month-end.

2. 02

   Get the details right first time

   Check the customer's legal name, GSTIN, billing address, purchase order number, rates, quantities and tax. An invoice sent back for correction usually restarts the customer's approval cycle. Our GST invoice checklist lists the fields to check.

3. 03

   Show the due date, not just the terms

   Write the actual due date on the invoice alongside the terms, and show your bank details or UPI details clearly so paying is easy.

4. 04

   Send it to the person who pays

   Send the invoice to the accounts contact as well as the buyer, and ask for an acknowledgement of receipt. Keep proof of delivery, such as the signed challan, with the invoice.

An ageing list shows every unpaid invoice grouped by how long it has been outstanding. Most accounting software can produce one; a spreadsheet also works. Choose buckets that match your own terms, for example not yet due, recently overdue, overdue for longer, and seriously overdue. The exact boundaries are your choice.

• Sort by amount within each bucket, so the largest overdue balances get attention first.
• Add a column for the last contact, the promise made, and the next follow-up date.
• Mark disputed invoices separately, so they are not chased as if they were simply late.
• Watch concentration: if one or two customers hold a large share of what is owed, a single delay from them can squeeze your cash.

Pick one fixed slot each week, the same day and time, to work through the ageing list. Consistency matters more than tone: customers learn quickly which suppliers follow up and which do not.

A dispute is a reason, not an excuse, until you know which one it is. Ask the customer to state in writing what is wrong and which amount is affected. Then act quickly on your side.

1. Separate the disputed amount from the undisputed amount, and ask for the undisputed part to be paid now.
2. Check the facts: the purchase order, the delivery challan, the quality report, the agreed rate.
3. If you were wrong, issue the correction or credit note promptly so the rest of the invoice can be paid.
4. If you were right, send the evidence and a clear request for payment.
5. Keep all correspondence together with the invoice.

A dispute left open for weeks usually becomes a much larger delay. Most of them are settled by one conversation between people who can decide.

Decide your rule before you need it, and tell customers what it is when you agree terms. A common approach is to pause new credit orders when a customer goes over their credit limit, or when an invoice stays overdue beyond a point you have chosen, until the account is brought back within terms. You can still supply against advance payment in the meantime.

If your business is a micro or small enterprise with Udyam registration, the Micro, Small and Medium Enterprises Development Act, 2006 protects you when a buyer pays late. In principle, section 15 requires the buyer to pay by the date agreed in writing, and the agreed period cannot exceed a maximum set by the Act. Section 16 makes a buyer who pays late liable to pay compound interest to the supplier, and that liability applies despite anything to the contrary in the agreement between you.

Where the amount is not paid, the supplier can refer the dispute to the Micro and Small Enterprises Facilitation Council for the state, which can conciliate and, if that fails, arbitrate. Applications can be filed online through the government's MSME Samadhaan portal, which is open to micro and small enterprises with valid Udyam registration.

Another option for MSMEs selling to larger buyers is TReDS, the Trade Receivables Discounting System regulated by the Reserve Bank of India. On a TReDS platform, an MSME's invoices on eligible buyers can be financed by banks and other approved financiers, and the Reserve Bank states that these transactions are without recourse to the MSME.

Your ageing list is the main input to the collections line of any cash forecast. Place each customer's balance in the week they are actually likely to pay, based on the promises you recorded and how they have paid before, not on the invoice due date. Leave disputed amounts out of the main forecast until they are resolved.

Once a month, look at the overall picture: how much is overdue, which customers hold most of it, and whether collections are getting faster or slower. Our guide to building a 13-week cash-flow view and our monthly finance dashboard guide show where these numbers fit.
