Accounts Receivable Management: A Practical System for Small Businesses

Sales are only half of the story. Until the customer pays, an invoice is a promise, and a business with healthy sales can still run out of cash if too many promises are outstanding. Accounts receivable (AR) management is the system that turns invoices into cash on time.

This guide sets out a simple AR system for Indian small and mid-sized businesses: the policies, the reports, the routine and the specific Indian complications such as TDS short-payments and MSME rules.

What is accounts receivable, and why manage it actively?

Accounts receivable is the total amount customers owe you for goods or services already supplied on credit. It appears as "sundry debtors" or "trade receivables" in your balance sheet.

Active management matters because:

• Cash is tied up. Every rupee in receivables is a rupee you cannot use for stock, salaries or GST payments.
• GST is paid before you collect. Output tax is due when you supply, not when you are paid, so slow collections mean you fund the tax yourself. See bad debts and GST.
• Old debts go bad. The longer an invoice stays unpaid, the less likely it is to be collected.

What policies should an AR system start with?

Write these down, even on one page, and share them with your sales team.

Policy	Example
Standard credit period	15 days from delivery; 30 days for approved distributors
New customer terms	Advance or cash on delivery for the first 3 orders
Credit limit	Starts at ₹50,000; reviewed every 6 months
Overdue limit	No new credit supplies if any invoice is over 30 days overdue
Advances	30% advance on orders above ₹2,00,000 or custom items
Escalation	Owner calls at 15 days overdue; final notice at 30 days
Write-off approval	Only by owner/partner, with documented recovery attempts

If you are a Udyam-registered micro or small enterprise, keep agreed credit within 45 days; the MSMED Act gives you interest rights on delays. See the MSME 45-day payment rule.

How do you build and read an ageing report?

An ageing report groups each customer's unpaid invoices by how long they have been outstanding, usually from the due date or invoice date.

Example ageing report (as on 31 October 2026)

Customer	Not yet due	1–30 days overdue	31–60 days	61–90 days	Over 90 days	Total
Nagpur Traders	₹80,000	₹40,000	–	–	–	₹1,20,000
Hubli Steel Works	₹1,50,000	–	₹60,000	–	–	₹2,10,000
Surat Fabrics	–	₹25,000	₹30,000	₹45,000	–	₹1,00,000
Indore Builders	–	–	–	–	₹70,000	₹70,000
Total	₹2,30,000	₹65,000	₹90,000	₹45,000	₹70,000	₹5,00,000

How to read it:

• ₹2,30,000 (46%) is not yet due – healthy.
• ₹2,05,000 (41%) is 31 days or more overdue – the focus for action.
• Surat Fabrics has invoices in three buckets: a pattern of slipping, worth a call and possibly a credit hold.
• Indore Builders at over 90 days needs a final notice and a decision on provision.

Check: ₹2,30,000 + ₹65,000 + ₹90,000 + ₹45,000 + ₹70,000 = ₹5,00,000.

How do you calculate days sales outstanding (DSO)?

DSO estimates how many days, on average, it takes to collect a sale.

DSO = (Closing trade receivables ÷ Credit sales for the period) × Number of days in the period

Worked example

A Hyderabad packaging supplier has credit sales of ₹27,00,000 for July–September 2026 (92 days) and receivables of ₹13,50,000 on 30 September.

DSO = (₹13,50,000 ÷ ₹27,00,000) × 92 = 0.5 × 92 = 46 days

Its standard terms are 30 days, so customers are paying about 16 days late on average. Daily credit sales are ₹27,00,000 ÷ 92 ≈ ₹29,348. Bringing DSO down to 35 days would free roughly 11 × ₹29,348 ≈ ₹3,22,800 of cash.

Track DSO monthly. The trend matters more than any single figure.

What does a weekly AR routine look like?

1. Invoice everything delivered in the last week; no batching.
2. Apply all receipts to specific invoices, including UPI, NEFT, cheques and cash.
3. Record deductions correctly – TDS, discounts and short payments – so balances are real.
4. Run the ageing report and sort by amount over 30 days.
5. Assign a next action and owner to each overdue item: reminder, call, statement, or credit hold.
6. Send scheduled reminders using consistent wording; see payment reminder templates.
7. Log promises to pay with dates and check them on that date.
8. Update credit holds for customers over their overdue limit.

Billing Software by Betterwork can generate ageing reports and send payment reminders with UPI links automatically, so the weekly routine focuses on calls and decisions rather than data entry.

How do you handle Indian-specific deductions and adjustments?

TDS deducted by customers

When a customer deducts income-tax TDS, the invoice is fully settled: part in cash, part as TDS receivable. Record it as such, then match it with the customer's Form 131 certificate (which replaced Form 16A under the Income-tax Act 2025). Leaving it as "short payment" inflates receivables. See TDS on invoices.

UPI and card charges

From 15 October 2026, NPCI's FAQ sets a 0.4% MDR on P2M UPI payments above ₹2,000, capped at ₹300. Book the charge as an expense; do not leave it as an unpaid balance on the customer's ledger. See UPI payments for business.

Credit notes and returns

Returns, rate corrections and deficiency claims should be settled through proper GST credit notes so both your ledger and GST returns reflect them.

Customers' 180-day ITC rule

Under section 16(2) of the CGST Act, a business customer that has not paid you within 180 days of the invoice date must reverse the input tax credit it took, with interest. That gives registered customers a tax reason to clear old invoices.

How do you decide credit limits?

A simple, defensible approach:

1. Start new customers on advance or low limits.
2. Review after 3–6 months of history: average days to pay, disputes, order volume.
3. Set the limit near one credit period of expected purchases, for example a customer buying ₹2,00,000 a month on 30-day terms gets roughly ₹2,00,000–₹2,50,000.
4. Cut limits quickly when payment behaviour worsens.
5. Record limits in your billing system so sales staff see them when creating orders.

Which AR metrics should you track each month?

DSO is the headline number, but a few more measures show where the problem lies.

Metric	How to calculate	What it tells you
DSO	Receivables ÷ credit sales × days	Average time to collect
% overdue	Overdue amount ÷ total receivables	How much of AR is late
% over 90 days	Amount over 90 days ÷ total receivables	Bad-debt risk
Collection effectiveness	Cash collected ÷ (opening receivables + credit sales − closing current receivables)	How well you collect what is collectable
Top-10 concentration	Top 10 customers' balance ÷ total receivables	Dependence on a few payers
Disputed amount	Total of invoices on hold for disputes	Process and quality issues

Pick three or four and review them monthly with the same definitions, so trends are comparable.

Worked example: overdue percentage

From the ageing report above, overdue amounts total ₹65,000 + ₹90,000 + ₹45,000 + ₹70,000 = ₹2,70,000. Overdue percentage = ₹2,70,000 ÷ ₹5,00,000 = 54%. Amounts over 90 days are ₹70,000 ÷ ₹5,00,000 = 14%. A target might be to bring overdue below 30% and over-90 below 5% within two quarters.

How do you organise roles for collections?

In a small business, one person may do everything, but the responsibilities should still be clear:

• Sales: agrees terms, collects customer billing details, warns of disputes early.
• Billing/accounts: invoices on delivery, applies receipts, sends statements and reminders.
• Owner or finance head: approves credit limits, handles escalations, decides write-offs.

Write the names next to each role. When everyone knows who chases which customer, overdue lists shrink. Review the roles whenever staff change, because collections are often the first task to be dropped during a handover, and a customer who notices that nobody is chasing will quietly move you to the bottom of the payment queue.

How do you clean up an old, messy receivables ledger?

Many businesses start AR management with a ledger full of unexplained balances. Clear it in stages:

1. Freeze a cut-off date, such as the last day of the previous month, and work only on balances up to that date.
2. Sort balances by size. Clear the largest ten customers first; they usually explain most of the total.
3. Match each receipt to an invoice. Unallocated receipts sitting "on account" are the most common reason balances look overdue when they are not.
4. Explain small differences. Short payments are typically TDS, payment charges or rounding. Post each to the correct account rather than writing them off in bulk.
5. Send statements to customers with remaining balances and ask them to confirm or dispute within a fixed time, such as 10 days.
6. Escalate genuine disputes to the person who made the sale, with copies of the order, delivery proof and invoice.
7. Review truly old items with your accountant before treating them as bad debts.

Once the old ledger is clean, the weekly routine above keeps it that way.

Common mistakes in accounts receivable management

• Unapplied receipts sitting on accounts, making ageing reports meaningless.
• Ignoring small balances from TDS, MDR or rounding that pile up.
• No owner for collections; everyone assumes someone else is chasing.
• Sales staff overriding credit holds without approval.
• Chasing only when cash is short, rather than on a fixed rhythm.
• Never sending statements, so missing invoices go unnoticed for months.
• Late write-off decisions, which overstate assets.

Key takeaways

• Write a short credit policy covering terms, limits, advances and escalation.
• Review an ageing report weekly and act on everything over 30 days.
• Track DSO monthly and compare it with your average credit period.
• Record TDS, MDR and credit notes correctly so receivables show the real amount owed.
• Assign every overdue invoice a next action, an owner and a date.
