9. Accounts Receivable basics

Accounts Receivable (AR) is one of the most important functions for business health, cashflow, GST accuracy, and customer relationship management.

1. Introduction — Why Accounts Receivable Matters

Accounts Receivable represents the money owed to the business by its customers.For most SMEs and startups, revenue is only meaningful when it converts into cash. Poor AR management leads to:
  • Cashflow shortages
  • Dependence on loans
  • Bad debts
  • Customer disputes
  • GST paid on unpaid invoices
  • Weak working capital cycle
A strong AR process directly improves liquidity, business stability, and growth capacity.
Key Points:• AR is not just accounting — it is a cashflow engine.• Timely collections reduce loan dependency.• AR accuracy affects GST, TDS, and Income Tax compliance.• Clear AR processes prevent disputes and write-offs.

2. Objective

To provide a simple, structured understanding of Accounts Receivable, its importance, best practices, and how to design a system that ensures timely collections and accurate books.

3. Core Concepts — What Is Accounts Receivable?

Accounts Receivable (Debtors) are the unpaid invoices for goods or services delivered.
AR includes:
  • Invoices issued
  • Customer credits
  • Advances received
  • Debit notes
  • Outstanding balances
  • Ageing analysis
AR exists until the customer pays and the receipt is posted.

4. How Accounts Receivable Works — The Flow

Step 1 — Sale is Recorded

Business issues a sales invoice.

Step 2 — Customer Ledger is Updated

Invoice amount is debited to customer account.

Step 3 — Payment is Received

Bank/cash entry is posted.

Step 4 — AR is Reduced

Ledger balance decreases.

Step 5 — Reconciliation

Ensure customer balance = actual outstanding.

Step 6 — Follow-Up & Collection

Communication is made based on ageing.
A disciplined AR cycle ensures smooth cashflow.

5. CABTA Framework — “The 5 Pillars of AR Control”

A practical model designed for SME and startup environments:


Pillar 1 — Accurate Invoicing

Strong AR begins with clean invoices.Invoices must include:
  • Correct customer name & GSTIN
  • Description of goods/services
  • PO number or agreement reference
  • Due date
  • Payment terms
  • Tax breakup
  • Contact for billing issues
Bad invoice = delayed payment.

Pillar 2 — Customer Master Data Discipline

Maintain a clean customer database with:
  • Legal name
  • GSTIN
  • Billing address
  • Contact details
  • Payment terms
  • Credit limit
  • TDS category
A wrong GSTIN or customer name creates compliance issues and risks of mismatches.

Pillar 3 — Accurate Posting & Reconciliation

Monthly AR reconciliation ensures:
  • No missing invoices
  • No duplicate invoices
  • Proper money allocation to invoices
  • Correct credit notes
  • Zero unadjusted advances
  • Proper TDS computation
Mismatch between books and customer confirmation is a red flag in audits.

Pillar 4 — Ageing Analysis & Follow-Up Process

Ageing buckets:
  • 0–30 days
  • 31–60 days
  • 61–90 days
  • 90+ days
Follow-up strategy:
  • Soft reminder after 3–5 days of due date
  • Formal reminder at 15 days
  • Escalation at 30 days
  • Legal notice or hold supply beyond 90 days (if business policy allows)
Ageing reveals collection quality and customer health.

Pillar 5 — Collection Discipline

A disciplined AR team ensures:
  • Customers receive invoices on time
  • Regular reminders
  • Proper documentation of disputes
  • Receipt allocation is timely
  • Escalation happens early
  • No overdue is ignored
Cashflow improves dramatically when AR is treated as an active function, not passive.

6. Common AR Issues Faced by SMEs

• Invoices sent late or with errors• No follow-up for overdue payments• Poor customer data• Misallocation of receipts• Missing TDS information• GST mismatch due to incorrect invoice posting• Unreconciled debit notes• Advances not adjusted• Unrealistic credit terms• No customer confirmations
These issues lead to financial stress and compliance problems.
