Tally, spreadsheets or online books: an honest comparison for a 5-person firm

Updated for FY 2026-27 (AY 2027-28).

Most five-person firms in India run their books on whatever the first accountant used, and nobody revisits the decision for a decade. The real cost shows up quietly — a GSTR-3B filed from a half-reconciled bank column, a TDS short-deduction notice, a partner who cannot see last month's profit without asking someone. This piece compares the three honest options on the work a five-person firm actually does, with figures.

What a five-person firm has to produce every month, regardless of tool

Before comparing tools, write down the output. For a typical five-person services firm or small trading business with GST registration, it is:

• Sales invoices raised and the GSTR-1 summary ready by the 11th of the next month.
• Purchase bills entered, input tax credit matched to GSTR-2B, GSTR-3B by the 20th (or quarterly under QRMP if turnover is up to ₹5 crore).
• TDS deducted correctly at the time of credit or payment — 194J at 10% on professional fees above ₹50,000 a year, 194C at 1%/2% for contractors above ₹30,000 a single bill or ₹1,00,000 in aggregate, 194I at 10% on rent above ₹6,00,000 a year, 194H at 2% on commission above ₹20,000 — and 24Q/26Q filed each quarter.
• Salaries, PF and professional tax posted, not just paid.
• Every bank line explained. Not categorised roughly; explained, so the closing balance in the books equals the balance on the statement.
• Advance tax on 15 June (15%), 15 September (45%), 15 December (75%) and 15 March (100%), with 234B/234C interest if you fall short.

That is between 150 and 600 transactions a month for most firms this size. The tool question is simply: which one gets those six outputs done with the fewest hours and the fewest re-dos.

Spreadsheets: fine until the second person touches them

A spreadsheet is the cheapest and fastest thing to start with, and for a one-person freelancer billing six clients a month it is genuinely adequate. For five people it usually fails on four specific points.

First, single entry. A sheet records a payment; it does not record both sides. So you can have a "profit" figure that no balance sheet supports, and no trial balance to prove it. When your CA asks for opening and closing creditors at year end, somebody reconstructs them from memory.

Second, no audit trail. Anyone can change a March figure in November, and nothing records it. If a dispute or a scrutiny comes up, you cannot show that the books were not edited after filing.

Third, bank reconciliation by eye. Five hundred lines pasted from a PDF statement, matched manually against a sales sheet, is where the hours go — and where the errors hide. A missed ₹1,18,000 vendor payment is both a wrong bank balance and a lost ₹18,000 of ITC.

Fourth, GST and TDS logic has to be re-written by hand every year. Rates, thresholds and the 2B matching all become formulas that one person understands.

Spreadsheets stop making sense roughly when you cross about 100 transactions a month or add a second person who enters data.

Tally: strong accounting, heavy habits

Tally is a real double-entry system and the default language of most Indian CAs. Ledgers, vouchers, groups, cost centres — your accountant and auditor already know it, and that is worth something.

The honest costs for a five-person firm are these. It is paid software with licences priced by the vendor, plus annual renewals; check current rates directly before budgeting. It is desktop-first, so multi-user access and remote work mean a server, a remote-desktop arrangement or a sync setup that somebody has to maintain. Backups are your problem. Bank reconciliation is largely manual unless you build or buy an import routine. And there is a real training cost — Tally rewards people who know the keyboard and punishes people who do not, so data entry tends to concentrate in one person, which is a key-person risk for a firm of five.

If you have a full-time accountant who already knows it, this is a perfectly defensible choice. If you do not, you are paying for software plus a skill you have to hire for.

Online double-entry: what actually changes

Online accounting is the same double entry, with three differences that matter at this size.

The bank statement is the spine. You upload a PDF, CSV or Excel statement — or, with banks like HDFC, IDFC FIRST and Aspire, read the transactions directly — and work down the list until every line is explained. Rules learn your recurring entries, so the AWS debit and the office rent categorise themselves from the second month. Our bank statement reconciliation guide sets out the routine.

Access is by role. The two partners see the P&L, the office manager raises invoices, the CA gets a read-only auditor login instead of a WhatsApp'd backup file.

Nothing is silently editable. A tamper-evident audit log means a change to a posted entry leaves a record.

The trade-off: you depend on an internet connection, and your CA may still want a Tally-format export at year end, so check that the export exists before you move.

A worked example: what proper books are worth in rupees

Take Meera, a proprietor running a five-person design consultancy. FY 2026-27 gross receipts ₹72,00,000, all by bank transfer. Salaries, rent, software and contractor costs come to ₹50,00,000, so her actual profit is ₹22,00,000.

She is eligible for presumptive taxation under 44ADA (professionals, receipts up to ₹75 lakh, cash receipts under 5%), which deems income at 50% of receipts — ₹36,00,000.

Option A — 44ADA, no books. Total income ₹36,00,000, new regime:

Option B — real books, actual profit ₹22,00,000. Same slabs: ₹20,000 + ₹40,000 + ₹60,000 + ₹80,000 + 25% on ₹2,00,000 (₹50,000) = ₹2,50,000, plus 4% cess ₹10,000 = ₹2,60,000.

The difference is ₹4,26,400 for one year. Declaring below the presumptive rate brings maintenance-of-books and possible audit obligations — confirm the position for your case with your CA — but even a full audit fee is a fraction of that gap. The point is simple: for a five-person firm with real salary and rent costs, the books are not overhead. They are the cheaper tax position, and they only exist if the tool makes entry easy enough to keep up.

One entry, three ways

Meera engages a freelance illustrator for ₹1,00,000 plus 18% GST. Section 194J applies at 10% on the fee.

In a spreadsheet, this is typically one line: "paid illustrator ₹1,08,000". The ₹18,000 ITC and the ₹10,000 TDS liability both live in somebody's head until the 20th. In Tally or an online system, the entry above creates the creditor, the ITC for GSTR-3B and the TDS payable for 26Q in one go — and the ₹1,08,000 bank line later matches against the creditor instead of being coded afresh.

That single structural difference is most of the argument.

Scoring the three on what matters at five people

The pattern for most five-person firms: spreadsheets below roughly 100 transactions a month, Tally if you already employ someone fluent in it, online double entry if you want two or three people entering data and your CA reviewing without a file transfer. CA firms running many client sets have a separate calculus — see the notes for CA firms.

Doing this in FlipAccounts

FlipAccounts is free online double-entry accounting, with no card and no transaction limits, so you can run a parallel month before deciding anything. Upload a bank statement under Banking, work the reconciliation list until every line is explained, and let the rules remember your recurring vendors. Invoices and bills carry GST and TDS, which feed the GSTR-1, GSTR-3B and TDS summaries; the statements pack gives P&L, balance sheet, trial balance and general ledger, with Excel and Tally exports for your CA. Add your CA as a read-only auditor under multi-company roles, and the tax computation screen will compare new and old regime on the numbers in your books. There is more on the GST side in the free GST accounting guide.

What to do this week

1. Count last month's transactions — bank lines, sales invoices, purchase bills. Under 100, your spreadsheet is probably fine for now; over 300, it is already costing you more hours than any tool.
2. Pull your 31 March bank statement balance and your books' closing balance for the same date. If they differ, that is the real state of your accounting, not the tool.
3. Run one month in parallel in a second system — same invoices, same bills, same statement — and compare the time taken and the closing figures before committing.

Frequently asked questions

Will my CA accept books kept outside Tally?

Most will, provided you can hand over a trial balance, general ledger and ledger-wise detail in a format they can import. Ask your CA which export they prefer before you switch, and test one month's export end to end rather than discovering a mismatch in July.

Can I move mid-year, or must I wait for 1 April?

You can move mid-year. The cleaner approach is to pick a date, post opening balances as at that date from a signed trial balance, and keep the old system read-only for the earlier months. Moving at the start of a quarter also keeps your GST and TDS return periods tidy.

Is presumptive taxation under 44ADA always worse than keeping books?

No. If your actual profit is close to or above 50% of receipts — common for a solo professional with few costs — 44ADA saves work and tax is similar. It is the firm with real salaries and rent, like the ₹22 lakh profit on ₹72 lakh receipts above, where books win clearly. Check the audit implications for your case with your CA.

How many people should be entering data in a five-person firm?

Two, with a third reviewing. One person entering is a key-person risk; four is a consistency problem. Role-based access helps: one raises invoices, one enters bills and does the bank reconciliation, and the owner or CA reviews the trial balance monthly.
