Monthly accounting documents checklist

Late or missing paperwork causes more month-end trouble than difficult accounting. Use the core list, add the part for your kind of business, and adapt it to your business.

Sources checked November 2026. Based on the official and published sources cited here. For your own case, Deepak Mittal reviews the position with you directly.

The short answer: each month, send statements for every bank account, your sales invoices or sales register, purchase and expense bills, your cash record, loan statements, and a note of who each payment came from or went to. Add GST, TDS and payroll papers if they apply to you, plus the extra items for your kind of business listed below.

The core list, for almost every business

DocumentWhy it is neededWhere it usually goes wrong
Bank statements, every accountTo reconcile the books against actual moneyA rarely used account or a personal account used for business is left out
Sales invoices or sales registerTo record income and prepare GST sales dataCancelled invoices and credit notes are not included
Purchase bills and expense billsTo record costs and support any input tax creditBills reach you after month end, or stay with staff
Cash and petty cash recordTo account for money that never touched the bankCash spends with no voucher
Loan and EMI statementsTo split principal from interestOnly the EMI total is known
Payments to suppliers and from customers, noted against partiesTo keep balances correctBank entries with no clue who paid or why

Add these if they apply to you

  • Registered for GST: any e-way bills, debit and credit notes, and the supplier-side data Deepak Mittal asks you to review.
  • You deduct TDS: details of each payment, deduction and challan for deposit, including rent and contractor payments where applicable.
  • TDS is deducted from you: certificates or statements received, so credits can be matched.
  • You have staff: attendance, salary changes, joiners and leavers, advances, plus PF and ESI records where applicable.
  • You bought or sold an asset: the invoice or sale document.
  • The owner put in or took out money: a note of what it was for, so it is not treated as sales or expense.

A folder system that takes ten minutes to set up

Create one folder per month, in the same way each time, on a drive you control:

2026-11
  01-bank
  02-sales
  03-purchases-and-expenses
  04-cash
  05-gst
  06-tds
  07-payroll
  08-notes-for-accountant.txt

Name each file so that it can be found later, for example 2026-11-supplier-name-invoice-123.pdf. Use the notes file for anything odd: a personal payment from the business account, a disputed invoice, or a one-off receipt. A two-line note can save a long back-and-forth.

A simple routine

  1. Weekly: photograph or file bills as they arrive, so they do not stay in wallets and drawers.
  2. On the first working day of the month: download the bank and settlement statements.
  3. By the date agreed with Deepak Mittal: send the folder. Ask for that date in writing, working back from your filing dates.
  4. After they finish: review their list of queries, and answer them while you still remember.

We have not listed due dates here because they can change and may vary by your filing scheme. Confirm yours on the GST portal (opens in a new tab), on the income tax portal (opens in a new tab), or with Deepak Mittal.

Sharing documents safely

A checklist is about documents, not access. Do not send passwords or OTPs with your monthly pack. Share files through a method you have agreed with Deepak Mittal, and know who else can open them. The hiring guide explains how to keep control of portal and software access.

This is general guidance, so your business may need more or less. See what to prepare before you speak with AccountOrbit.
