Tally Prime vs 21bill — Do You Really Need ₹18,000/year Accounting Software?

Tally is a brand. In India, saying “Tally” is like saying “Xerox” — it means “accounting software” by default, even when someone’s using Zoho or Busy. For 30 years, if you had an SMB and a CA, your CA told you to buy Tally.

In 2026, that default is breaking. Not because Tally is bad — it’s still the gold standard for accounting depth — but because most small businesses are paying ₹18,000/year for features their CA uses once a month and they never open.

This post is on the 21bill blog, so the bias is obvious. But I’ll lay out the numbers honestly: who should still buy Tally, and who’s paying for things they don’t need.

The raw cost comparison

	Tally Prime Silver (single user)	21bill Starter	21bill Business
First year	₹18,000 + 18% GST = ~₹21,240	₹99/mo × 12 = ₹1,188	₹299/mo × 12 = ₹3,588
AMC from year 2	~₹5,400/year (subscription renewal)	Same	Same
Multi-user	₹54,000 Gold + AMC	Included up to 5 users	Included up to 5 users
Cloud access	Paid add-on (Tally on AWS)	Included	Included
Installation	Desktop Windows only	Any browser	Any browser

For a small business, the 3-year cost:

• Tally Silver: ₹21,240 + ₹5,400 × 2 = ₹32,040
• 21bill Business: ₹3,588 × 3 = ₹10,764

The Tally premium is ₹21,000+ over three years for a single-user, single-device setup. Multi-user Tally Gold is nearly 30× that.

What Tally does that we don’t

This is the short list of things where Tally is still objectively better and worth the money if you need them:

1. Real double-entry accounting

Tally is a full accounting system — journal entries, ledgers, trial balance, P&L, balance sheet, depreciation, fixed asset registers, cost centres, cost categories, stock valuations, manufacturing bills of materials. If your business has any of these needs, Tally earns its keep:

• You have a manufacturing unit with raw materials → work-in-progress → finished goods accounting.
• You need cost centre reporting across projects / branches.
• Your CA uses ratio analysis, budget vs actual, variance reporting.
• You do consolidated accounts across multiple companies.

21bill is billing + GST + basic receivables/payables. We don’t do ledgers, journals, or balance sheets. We’re not trying to.

2. CA muscle memory

Your CA has been entering data into Tally for 20 years. They can type faster in Tally than in any modern UI. If your CA is reluctant to learn a new tool and they’re integral to your monthly workflow, Tally-on-their-desktop is the path of least friction.

3. Offline-first desktop reliability

Tally runs locally. Your data is on your hard drive. No cloud means no monthly subscription drift, no vendor lock-in, no “our servers are down today.” For businesses in areas with genuinely unreliable internet, this matters.

4. E-invoicing for ₹5Cr+ turnover businesses

Tally’s e-invoicing integration is mature — IRN generation, QR codes, all automated. If you’re crossing the ₹5Cr turnover threshold where e-invoicing is mandatory, Tally handles it natively. We plan to support this in Q3 2026 but don’t today.

5. Complex tax scenarios

Reverse charge mechanism (RCM), Export with LUT, SEZ supplies, advance receipts, TCS, TDS, job work, composite supply — Tally handles the full matrix. 21bill handles the standard GST cases (B2B, B2CS, B2CL, credit/debit notes, HSN summary) and we’re adding the edge cases as paying users ask.

What 21bill does that Tally struggles with

1. Being usable from a phone

Tally is Windows desktop software. Tally on mobile — via their cloud offering or third-party wrappers — is a bolted-on afterthought. If you ever want to raise an invoice while away from your desk (at a customer’s office, at an exhibition, from home), Tally makes this painful.

21bill is browser-first. Open the app on any phone, laptop, or tablet and you’re in. Your data syncs across all of them automatically.

2. Multi-device collaboration

In Tally, if your accountant is working on the books at their office and you open the company file, you’ll collide. Multi-user Tally requires Tally Gold (~₹54k + AMC) and a complex server setup.

21bill is built multi-user from day one. Your cashier creates an invoice on the shop tablet, your salesperson updates a quotation on their phone, your CA pulls filing data from their office — simultaneously, no conflicts, no licence counting.

3. GST filing JSON in one click

Tally can generate GSTR-1 / GSTR-3B files, but the workflow is:

1. Alter the company for the right period
2. Run the report
3. Export to JSON
4. Open Tally’s return-filing utility
5. Validate the JSON
6. Upload to gst.gov.in

That’s 15-20 minutes per month, done by someone who knows Tally deeply (usually your CA). 21bill: open /reports/filings, pick the month, click download. 30 seconds.

4. No licence management

Tally Silver is one user. Adding a second user = Tally Gold. Moving Tally to a new computer = licence transfer (a form, a phone call, 48 hours). Losing your Tally dongle = lost licence until you buy a new one.

21bill is a subscription. We add users, we move between devices, we handle the licence layer. You log in with an email and password.

5. Honest pricing

Tally’s pricing hasn’t genuinely changed much since 2010. ₹18,000 Silver + ₹54,000 Gold + AMC renewals + add-on modules + payroll + e-invoicing. Half of Indian SMBs aren’t even sure which SKU they own — they bought it from a local reseller who installed it years ago.

21bill: ₹99, ₹299, or ₹599 per month. Published. Cancel any time.

Who should absolutely stay on Tally

• Manufacturing businesses with real inventory accounting, BOMs, job work.
• Businesses above ₹5Cr turnover needing mature e-invoicing.
• Practices managing 10+ client companies (like CAs themselves) — Tally is where they live professionally.
• Anyone whose CA refuses to work on anything else. This is a real constraint; respect it.

Who should consider switching

• Trading / retail / services businesses doing invoice-in, invoice-out, and wanting GST returns. ~80% of Indian SMBs.
• Anyone paying Tally’s ₹18k/year for what reduces to “invoicing + GSTR export” — you’re leaving ₹7-15k/year on the table.
• Multi-branch businesses where everyone needs access but you don’t want the Tally Gold tax.
• First-time business owners who don’t have Tally muscle memory and won’t gain anything by starting with it.
• Businesses wanting modern, mobile, collaborative tools.

The migration question

The biggest blocker to switching off Tally isn’t the cost — it’s your historical data. Five years of ledgers, party masters, item masters. You can’t drop that.

Our honest answer: you probably shouldn’t abandon Tally in the middle of a financial year. Pick a clean break — 1 April 2027, when FY 2027-28 starts — and run 21bill for the new year while Tally holds your closing balances. Your CA can reconcile at year-end. This is the path most switches take, and it’s what we’d recommend to our own users.

For businesses that haven’t bought Tally yet — new registrations, first-time GST filers, businesses below ₹1 Cr turnover — just don’t buy Tally in 2026. The extra ₹17,000/year buys accounting features you’ll outgrow into before you need them.

The bottom line

If your current relationship with Tally is:

“My CA opens it once a month, types in my bills, exports GSTR-1, and I pay ₹3,500/month for this.”

You’re paying twice — once for the Tally licence you don’t touch, once for the CA who uses it as a data-entry tool. Replacing both with ₹299/month software that hands your CA a ready-to-file JSON saves you ~₹45,000/year.

If your CA actively uses Tally’s ledgers, trial balance, and financial statements to give you meaningful monthly business advice — keep Tally. That’s what it was built for.
