A small-business owner knows reconciliation is important but does not know which accounts to check first or how often, and so checks none of them regularly.
Reconcile first where money can leave or be lost unnoticed: bank, then cash, then customer receipts, then vendor payments, then TDS and GST credits. Each gets a fixed monthly slot.
A one-page monthly calendar: bank by the 5th, cash weekly, customers by the 10th, vendors by the 15th, TDS and GST credit checks before the GSTR-3B due date, each with a named preparer and reviewer.
Every month the business knows its true bank and cash position, who owes it money, what it owes suppliers and which tax credits are confirmed, with each check signed.
Start with the accounts where money can leave the business, or fail to arrive, without anyone noticing: bank, cash, customer receipts, vendor payments and tax credits (TDS and GST). Do them in that order, every month. Everything else can wait until the business is larger.
What is the order of priority?
| Priority | Reconciliation | Two records compared | What goes wrong if you skip it | Monthly slot |
|---|---|---|---|---|
| 1 | Bank | Cash book vs bank statement | Unrecorded debits, duplicate payments, bank charges and fraud go unnoticed | By the 5th |
| 2 | Cash | Cash book vs physical count | Shortages and unrecorded spending pile up | Daily or weekly |
| 3 | Customers (debtors) | Sales ledger vs receipts and customer statements | You lose track of who owes what; short payments are never chased | By the 10th |
| 4 | Vendors (creditors) | Supplier ledger vs supplier statements | Duplicate or missed bills; disputes with suppliers | By the 15th |
| 5 | TDS credits | TDS receivable vs Form 26AS, or Form 168 from tax year 2026-27 | TDS deducted by customers is never claimed | Quarterly, after TDS returns are filed |
| 6 | GST input credit | Purchase register vs GSTR-2B | Input tax credit is lost or claimed wrongly | Before filing GSTR-3B |
The dates are a suggestion. What matters is that each reconciliation has a fixed slot, so it happens without anyone having to remember.
Why is bank first?
Because the bank statement is the one record you did not create. If your books and the bank agree, almost every receipt and payment is accounted for. Bank reconciliation also catches problems that are expensive if missed: a cheque paid twice, a debit you never authorised, an EMI or NACH debit for the wrong amount, or a customer payment booked to the wrong party.
How much work is each one for a typical small business?
Take a business with one current account, about 50 sales invoices and 40 purchase bills a month, and a small cash counter.
| Reconciliation | Typical time each month |
|---|---|
| Bank (about 150 to 200 statement lines) | 2 to 3 hours |
| Cash (if counted daily) | 10 minutes a day |
| Customers | 1 to 2 hours |
| Vendors (top 10 suppliers) | 1 to 2 hours |
| TDS credits | 30 to 60 minutes, quarterly |
| GST input credit | 1 to 2 hours |
These are typical figures for a practised accountant, not fixed rules. The first month always takes longer because you are clearing old items.
What does that half day find? A typical first month for such a business might turn up a duplicate supplier payment of ₹14,750 (bank check), unrecorded bank charges of ₹1,180 (bank check), a customer short payment of ₹2,500 never chased (customer check), ₹6,000 of TDS deducted by a customer but not booked as TDS receivable (TDS check) and ₹3,240 of input GST on a bill missing from the purchase register (GST check). Together that is ₹27,670, most of it money the business can still recover.
What can you safely postpone until the business grows?
Some reconciliations matter less at small scale:
- Fixed asset register. With a handful of assets, a yearly check before the audit is usually enough.
- Minor vendor confirmations. Reconcile your top suppliers monthly and the rest quarterly.
- Intercompany. Only needed once you have more than one company in a group.
- Payment gateway and marketplace settlements. Needed once you sell online through Razorpay, Amazon or similar. If online sales are a small share, a monthly check is enough to start.
- Inventory to books. Important for traders and manufacturers, but usually done at stock-taking, not monthly, at small scale.
Do not postpone bank, cash or tax credits. A missed input tax credit or an unclaimed TDS credit is money the business has already paid.
Where do you go from monthly to daily?
Once you have more than one bank account, a busy cash counter or online sales every day, monthly is often not enough. The next guides explain when to move to daily checks and how to sequence the full month-end close.
