Bookkeeping Checklist for Small Businesses in India — Monthly, Quarterly, Annual

Most small businesses don't lose money on bad transactions — they lose it on bad records. Clean, current books give you GST compliance, faster credit decisions, painless audits and a real-time view of margin. Here is the bookkeeping cadence we run for every SME client.

1. Monthly tasks

• Record every sales invoice with GST breakup (CGST/SGST/IGST), HSN/SAC code, place of supply and payment terms.
• Record every purchase invoice, capturing ITC eligibility and vendor GSTIN.
• Book all bank transactions and credit card spends; auto-feed where possible.
• Maintain a petty cash register with supporting vouchers — random spot checks.
• Bank reconciliation at month-end for every account.
• GSTR-2B reconciliation against your purchase register — flag missing invoices and follow up with vendors before the next return.
• Payroll posting, TDS and statutory liability accruals.

2. Quarterly tasks

• TDS reconciliation — match Form 26AS / TRACES with books for both deductor and deductee positions.
• Advance tax computation and deposit (15 June, 15 September, 15 December, 15 March).
• Aged receivables and payables review; collections follow-up.
• Inventory count if you carry stock — physical vs system reconciliation.
• Management P&L and cash flow with 3-month forward outlook.

3. Annual / year-end close

• Depreciation schedules under both Companies Act (useful life) and Income Tax Act (block-of-assets).
• Provisions: gratuity (actuarial valuation if 10+ employees), leave encashment, bonus, warranty.
• Interest accruals on loans, prepaid expenses and accrued income.
• Related-party transactions schedule (Section 188 / AS-18 / Ind AS-24).
• GST annual reconciliation — GSTR-9 and GSTR-9C against audited books.
• Fixed asset register tag verification.

4. Common mistakes we see

• Mixing personal and business expenses on the same card or account.
• Issuing invoices without compliant GST formatting (missing HSN, place of supply, signed PDF).
• Not booking credit notes — leads to overstated revenue and overpayment of GST.
• Treating capital purchases as expenses (or vice versa).
• Letting GSTR-2B mismatches pile up — ITC starts getting reversed under Rule 36(4).
