Accounts Receivable (AR): Best Practices

Published on: July 29, 2026

Accounts receivable is the money your customers owe you for goods or services already delivered. On your balance sheet it sits as a current asset. In your bank account it is invisible — and that gap is where most Indian MSMEs lose sleep. You fulfilled the order, issued the invoice, paid GST on the output, and now wait 45, 60 or 90 days while salaries and vendor bills demand cash today.

Poor AR management is the leading cause of profitable businesses running out of cash. A company can show healthy revenue on the P&L and still fail because collections lag behind expenses. The fix is not aggressive calling alone. It is a system: clear credit policies, compliant invoicing, structured follow-up, and monthly ageing reviews that your CA can act on.

This guide covers AR best practices for Indian MSMEs in FY 2026-27 — setting credit terms, invoicing discipline, ageing analysis, the impact of GST and e-invoicing on collections, and the month-end review every finance team should run.

What is accounts receivable and why does it drain MSME cash flow?

Accounts receivable represents the total outstanding value of invoices you have issued but not yet collected. Every rupee in AR is a rupee you earned on paper but cannot spend.

The cash flow impact is structural, not incidental:

• You remit output GST in GSTR-3B based on invoiced supplies, often before the customer pays. Section 16 gives your buyer ITC on a valid invoice, but nothing in the CGST Act accelerates your collection
• Vendor payments typically run on shorter cycles — many suppliers demand 15 to 30 days while your customers take 60
• Working capital borrowing fills the gap, adding interest cost that never appears on the invoice you sent
• Bad debts — invoices you will never collect — require a write-off under Section 36(1)(vii) of the Income Tax Act, and only after the statutory conditions are met

Track Days Sales Outstanding (DSO) monthly. Divide total receivables by average daily credit sales. If your stated terms are 30 days and your DSO is 58, your collection process is broken regardless of how good your product is.

How should you set credit terms for Indian B2B customers?

Credit terms define when payment is due. They should be written, communicated before the first order, and enforced consistently.

A practical framework for MSMEs:

Document the terms in your quotation, purchase order acknowledgment and tax invoice. Indian courts and arbitration panels look at the invoice and the PO when a payment dispute arises — verbal agreements are difficult to enforce.

Review credit limits quarterly. A customer who was reliable at ₹2 lakh per month may become a risk at ₹15 lakh after a sudden volume increase.

What invoicing practices speed up collections?

The invoice is your collection instrument. A defective or incomplete invoice gives your customer's accounts payable team a legitimate reason to hold payment.

Issue the invoice on the day of supply. Section 31 of the CGST Act sets time limits — before removal for goods, within 30 days for services. Late invoicing means late payment starts from a later date and pushes your cash cycle out.

Include every Rule 46 field. Missing HSN codes, wrong place of supply, or absent buyer GSTIN are the top reasons large buyers reject invoices in their ERP. Our GST invoice format guide lists every mandatory particular.

Generate the IRN before sending if you are e-invoicing covered. Large buyers validate the IRN and QR code before releasing payment in their system. An invoice without an IRN is not a valid tax invoice under Rule 48(5), and savvy AP teams will reject it outright. Read E-invoice vs Regular Invoice for the compliance gap this creates.

Send the invoice to the right contact. B2B payment requires routing to the customer's accounts payable email or portal, not only to the purchase manager who placed the order. Confirm the AP contact during onboarding.

Attach supporting documents. Delivery challan, proof of delivery, purchase order copy, and LR or e-way bill for goods. AP teams batch-process payments once a week — incomplete files wait until the next cycle.

Use a consistent serial number series. Gaps or duplicates in your invoice numbering trigger audit queries and buyer suspicion. Start a fresh series each financial year.

How do you track ageing and follow up without damaging relationships?

Ageing analysis buckets outstanding invoices by how long they have been due. It is the single most useful AR report.

Standard ageing buckets:

Run the ageing report on the first working day of every month. Share it with sales, finance and the business owner in the same meeting.

Follow-up discipline that works:

• First reminder on the due date, not two weeks later. Many MSMEs wait until an invoice is 30 days overdue before sending the first email
• One owner per customer. Split responsibility creates gaps where each person assumes the other followed up
• Log every contact — date, person spoken to, promised payment date. This log is evidence if the matter goes to arbitration
• Offer a payment plan for genuine disputes, but only after the disputed amount is agreed in writing
• Use a credit hold flag in your ERP. Block new orders automatically when exposure crosses the limit or any invoice hits 60 days past due

Relationships survive firm process better than ad hoc nagging. Customers respect suppliers who invoice correctly and follow up predictably.

How does GST and e-invoicing affect your AR process?

GST changed AR from a simple debit-credit exercise into a compliance-linked collection workflow.

Key interaction points:

• Output tax liability arises on invoice date, not payment date. You owe GST in GSTR-3B for the period in which you issued the invoice, whether or not the customer has paid
• ITC linkage: your buyer claims credit based on your GSTR-1 data matching their GSTR-2B. If your invoice has errors, the buyer's IMS may flag it, and payment holds follow
• E-invoicing: covered taxpayers must report B2B invoices to the IRP and obtain an IRN. Buyers increasingly automate IRN validation — a missing or invalid IRN blocks payment in their workflow
• Credit notes: when you agree a price reduction or accept a return, issue a credit note under Section 34 with its own IRN if you are e-invoicing covered. This reduces the receivable and corrects the GST position
• TDS on payments: customers deduct TDS under Sections 194C, 194J or 194Q. Your receivable clears net of TDS, and the deducted amount becomes a TDS receivable tracked against Form 26AS

Reconcile your AR ledger to GSTR-1 monthly. Total invoiced value minus credit notes should match the movement in your receivable account, adjusted for opening and closing balances.

What should your month-end AR review include?

Block 90 minutes on the fifth working day of each month for a structured AR review. Invite the finance manager, sales head and business owner.

The checklist:

1. Print the ageing report as of the last day of the prior month
2. Verify the total against the receivable balance in the trial balance — they must match
3. List every invoice above 60 days past due with owner, last contact date and next action
4. Identify invoices without a matching IRN if you are e-invoicing covered — these are compliance failures and collection risks
5. Check credit notes pending issuance for known returns or disputes
6. Calculate DSO and compare to the prior three months — a rising trend needs immediate attention
7. Review customer concentration — if one buyer exceeds 25% of receivables, flag the exposure
8. Confirm bad debt provisions for invoices above 180 days where recovery is unlikely

Document the review in meeting minutes. Your CA uses this record when assessing the adequacy of provisions at year-end.

Practical recommendations for FY 2026-27

1. Publish written credit terms and apply them from the first quotation — no exceptions without owner approval
2. Invoice on the day of supply with every Rule 46 field complete and the IRN generated before the invoice leaves your system
3. Run ageing analysis monthly and assign one owner per overdue account
4. Send the first payment reminder on the due date — automate it through your accounting software if possible
5. Reconcile AR to GSTR-1 and the bank ledger every month as part of your monthly financial checklist
6. Cap exposure per customer at a level you can absorb if they default
7. Issue credit notes promptly — delayed corrections inflate receivables and create GST mismatches
8. Train your sales team that credit is not unlimited. Every sale on credit is a loan your business makes to the customer

Accounts receivable is where revenue becomes cash. A disciplined AR process converts the work you already did into the liquidity you need to run and grow the business.
