Most businesses treat late payment as a customer problem. The reminder goes out, the follow-up call gets made, the invoice ages another week, and the conclusion drawn is that this particular customer is unreliable. Sometimes that is accurate. More often the delay is manufactured by the collection process itself, and it repeats every cycle because nothing in the design prevents it from repeating.
The distinction matters because the two problems have different remedies. A behaviour problem is addressed with pressure. A design problem is addressed by changing the default.
The statutory clock has already moved
For anyone buying from small suppliers in India, delay stopped being purely a working capital question. Section 15 of the MSMED Act, 2006 requires payment to a registered micro or small enterprise within 15 days where no written agreement exists, or by the agreed date subject to an outer limit of 45 days.
Section 43B(h) of the Income Tax Act, effective from 1 April 2024, attached a tax consequence to that timeline. Miss it and the expense becomes deductible only in the year the payment is actually made, not the year it was incurred. Interest under the MSMED Act runs at three times the RBI bank rate, compounded monthly. The Income Tax Act 2025, in force from 1 April 2026, carries the same provision forward under renumbered clauses.
Applicability turns on the supplier’s Udyam classification. Micro and small are covered. Medium is not.
Where the delay originates
Under invoice-and-follow-up collection, no money moves unless the customer takes an action in that specific cycle. Someone opens the invoice, approves it internally, and initiates a transfer. Every one of those steps can slip for reasons unconnected to willingness to pay.
The default state of an invoice is unpaid. That single fact explains most of what collections teams spend their month doing.
A recurring payment system arrangement inverts it. The customer authorises collection once. From then on, the default state of each cycle is paid, and an active failure has to occur for money not to move.
What changes in practice
Collection stops depending on customer availability on a particular date. Follow-up work stops scaling with customer count. Receipt timing becomes predictable enough to plan against, which is often worth more than the recovered amount itself.
There is a diagnostic benefit that gets overlooked. When collection is manual, a late payment tells you almost nothing, because the cause could sit anywhere in the chain. When collection is automated, a failure returns a reason code. Insufficient funds and a cancelled mandate are different signals warranting different responses.
What a mandate does not fix
Automation does not create funds in an empty account. A customer without balance fails whether the debit is automatic or manual, and portfolios carrying real credit stress will still show failures.
Disputes are untouched. If a customer contests the amount, a mandate collects the disputed figure and generates a refund request rather than resolving anything. Billing accuracy has to hold before automation is worth having.
Nor does it remove follow-up entirely. It narrows follow-up to accounts that actually failed, which in most portfolios is a small fraction of the book.
The practical test
Take your last twelve months of receipts and separate late payments into two groups: customers who paid late because they could not pay, and customers who paid late because nobody collected on time.
If the second group is larger, the problem sits in the process rather than the ledger, and a recurring payment system addresses it directly. If the first group is larger, automation will make your reporting cleaner without improving your cash position much. That is still worth having. It is simply a different claim, and worth being honest about before the project gets approved on the wrong justification.
