Tally.ERP 9 TSS discontinued (Aug 2026): when Indian manufacturers and distributors should move to ERPNext instead of TallyPrime
Short answer
Tally Solutions’ upgrade page says that from August 16, 2026, TSS renewal is discontinued for Tally.ERP 9 licences. Tally.ERP 9 itself is not discontinued and keeps working, but without TSS you lose access to Tally’s updates and connected services. Customers whose TSS was active on or after November 9, 2020 qualify for a free upgrade to TallyPrime; others take a paid upgrade (checked Nov 12, 2026). Our view: if you mainly need accounting, GST returns and simple inventory, TallyPrime is the simpler move. Your team already knows Tally, and the upgrade keeps your data. Consider ERPNext if you are a manufacturer or distributor that has outgrown accounting-first software. Typical signs are several users across branches, production with bills of materials, purchase-to-pay approvals, batch tracking and a growing pile of spreadsheets around Tally. ERPNext is open source (GPL-3.0) with no licence fee. GST, e-invoicing and e-way bills are handled by the open-source India Compliance app; its GST API-based automation needs a paid India Compliance account. On Tally’s global pricing page, the TallyPrime International licence is USD 630 (Silver, single PC) and USD 1,890 (Gold, multi-user), one-time, each with one year of TSS. Licences for use in India are a separate India licence type, which we do not price here.

Who this guide is for
This guide is for owners, finance heads and operations managers at Indian small and mid-sized manufacturers and distributors that still run Tally.ERP 9. Since August 2026 you have had a forced choice: upgrade to TallyPrime, keep running Tally.ERP 9 without TSS, or move to something else. For many businesses TallyPrime is the right answer, and we say so. This guide is about the businesses for which it is not.
It is part of our series on legacy ERP deadlines; the legacy ERP end-of-support hub lists every vendor date we have confirmed.

A note on prices in this guide
This site shows prices in US dollars and pounds sterling only. We quote TallyPrime prices from Tally’s global (International) pricing page and Frappe Cloud’s published USD prices. Tally sells licences for use in India as a separate India licence type, priced in local currency, which we do not reproduce. Get that price from Tally or your Tally partner. We do not estimate implementation fees for any option.
What Tally actually changed in August 2026
| Question | What Tally’s upgrade page says |
|---|---|
| Is Tally.ERP 9 discontinued? | No. It is not being discontinued and will continue to work. TSS renewal for Tally.ERP 9 is discontinued. |
| From when? | From August 16, 2026, TSS renewal on Tally.ERP 9 is discontinued for all customers. |
| Can I renew TSS on Tally.ERP 9 after August 16? | No. You need to upgrade to TallyPrime and renew TSS there. |
| Who gets a free upgrade to TallyPrime? | Customers whose TSS was active on or after November 9, 2020: a free upgrade to the TallyPrime release available on their TSS expiry date. |
| Who pays? | Customers whose TSS expired before November 9, 2020 take a paid upgrade. |
| Does my licence change? | Tally says TallyPrime uses the same licensing system, so the existing licence and TSS subscription work with TallyPrime. |
| What about my data? | Tally says TallyPrime includes a data migration process that preserves existing data, and recommends a backup first. |
Tally lists the benefits of TallyPrime over Tally.ERP 9 as free cloud backup, connected banking, direct GST returns, enhanced analytics, e-invoicing integration, auto-reconciliation, remote access and automatic updates. In practice, the end of TSS on Tally.ERP 9 means the compliance and connected features your accountant relies on will drift out of date. For a GST-registered business, that is the real deadline, more than any date on the calendar.
The real question: accounting software or ERP?
TallyPrime and ERPNext are not the same kind of product, and treating them as straight substitutes leads to bad decisions in both directions.
| TallyPrime | ERPNext | |
|---|---|---|
| What it is at heart | Accounting, inventory and compliance software, very fast for trained users | Full ERP: accounting, buying, selling, stock, manufacturing, projects, CRM and HR in one database |
| Who uses it | Accountants and a few operations users | Finance, purchasing, stores, production, sales and management, each with their own role |
| Workflow and approvals | Limited | Configurable approval workflows on documents |
| Manufacturing | Bill of materials and manufacturing journals | Bills of materials, work orders, job cards, routing, subcontracting |
| Multi-branch, multi-company | Supported, often as separate companies | Multi-company and multi-warehouse in one site |
| GST, e-invoice, e-way bill | Built in | Through the open-source India Compliance app |
| Licence | Perpetual licence plus TSS (or rental) | No licence fee (GPL-3.0) |
| Learning curve for existing Tally users | Minimal | Significant; plan training |
Our rule of thumb: if Tally is used almost entirely by your accounts team, and operations run in Tally’s inventory or on paper and spreadsheets that work well enough, upgrade to TallyPrime. If operations teams keep spreadsheets alongside Tally because Tally does not cover their process, ERPNext is worth a serious look. Typical examples are production planning, purchase approvals, batch tracking, branch stock and customer-specific pricing.
Signs you have outgrown Tally
These are the patterns we look for when a business asks whether it needs an ERP. None of them alone means you must leave Tally. Three or more usually mean TallyPrime will solve your compliance problem but not your operations problem.
You have probably outgrown accounting-first software when
- Production is planned in spreadsheets and only the finished result is entered in Tally.
- Purchase requests and approvals happen on email or messaging apps, outside the system that records the purchase.
- Stores staff keep their own stock register because they cannot see or update stock where they work.
- Branch or warehouse stock is reconciled monthly by hand instead of being visible daily.
- Customer-specific prices, schemes or discounts live in a sales team spreadsheet.
- Management reports are built by exporting from Tally into Excel every month.
- You need batch or expiry tracking across purchase, production and sale, end to end.
- Several people need access with different permissions, and sharing one login has become a risk.
If most of these sound unfamiliar, upgrade to TallyPrime and revisit the question when the business changes. If most sound familiar, run the pilot described below before you renew anything for several years.
GST in ERPNext: the India Compliance app
The India Compliance app is an open-source app (GPL-3.0) built by Resilient Tech on top of ERPNext and the Frappe Framework. Its GitHub repository and documentation list these capabilities:
- GSTR-1 preparation with data mapping and error validation, and GSTR-3B
- Invoice Management System (IMS) actions for accurate GSTR-3B submissions
- Purchase reconciliation against GSTR-2B and GSTR-2A, including auto-reconcile
- e-Invoice and e-Waybill generation through integration with the NIC portal (IRP)
- GSTIN verification and document validation against government APIs
- TDS configuration, input service distribution, lower deduction certificates and an audit trail
Two things to understand before you plan. First, installation is straightforward: on Frappe Cloud you choose ERPNext and India Compliance when creating a site (Frappe version 14 or above, according to the docs), or install it with the Bench CLI on a self-hosted site. Second, the repository states that some automation features need access to GST APIs, which carry costs, so they require signing up for an India Compliance account. We do not quote those charges here; check them with the provider.
Test GST end to end in the pilot
Run a full month in the pilot: sales invoices with e-invoices, e-way bills for dispatches, purchase reconciliation against GSTR-2B, and a GSTR-1 and GSTR-3B preparation reviewed by your accountant. If your CA is not comfortable with the reports, fix that before go-live, not after.
Cost: what we can show in USD and GBP
| Item | Official price | Indicative GBP | Source |
|---|---|---|---|
| TallyPrime Silver (International licence, single PC), one-time | USD 630, includes one year of TSS | £472 | Tally global Buy TallyPrime page |
| TallyPrime Gold (International licence, multi-user on multiple PCs), one-time | USD 1,890, includes one year of TSS | £1,417 | Tally global Buy TallyPrime page |
| TallyPrime India licence | Priced separately in local currency | Not shown | Tally or your Tally partner |
| ERPNext licence | None (GPL-3.0) | None | ERPNext GitHub repository |
| ERPNext hosting on Frappe Cloud | Sites from USD 5 / month; servers from USD 40 / month | £3.75 / £30.00 a month | Frappe Cloud pricing page |
| India Compliance GST API usage | Paid account required for API-based automation; charges not quoted here | Not shown | India Compliance repository |
Indicative GBP conversions use the Bank of England daily spot rate (series XUDLUSS) of US$1.3335 per £1 for 10 Nov 2026, the latest published figure when we checked on Nov 12, 2026. They are not official UK prices: Tally and Frappe do not publish GBP list prices for these items, and your invoice currency, rate and VAT treatment may differ.
Read the table carefully. For a small business with a few users, a TallyPrime upgrade is likely to cost far less than any ERP implementation, and for many existing customers it is free. The case for ERPNext is never “it is cheaper than TallyPrime”. It is “we need an ERP, and ERPNext gives us one without per-user licence fees”. Implementation, training and support are the real cost lines for ERPNext. Get them quoted on your scope.
Mapping Tally to ERPNext
| Tally.ERP 9 | ERPNext | Notes |
|---|---|---|
| Company | Company | One Tally company per GSTIN or branch often becomes one ERPNext company with multiple addresses, or several companies; decide in discovery |
| Groups and ledgers | Chart of Accounts (group and ledger accounts) | Map Tally’s primary groups to ERPNext root types; rebuild sub-groups deliberately |
| Sundry Debtors and Sundry Creditors ledgers | Customers and Suppliers (with receivable and payable accounts) | Each party ledger becomes a party record, not a GL account |
| Cost categories and cost centres | Cost Centers and Accounting Dimensions | Keep the ones management actually reports on |
| Stock groups, stock items, units | Item Groups, Items, UOMs | Clean duplicate and inactive items before loading |
| Godowns | Warehouses | Nested by branch where needed |
| Batches and expiry | Batches | Load open batches with quantities and expiry |
| Bill of materials and manufacturing journals | Bill of Materials and Work Orders | A process change, not a data copy |
| GST registration, HSN/SAC, tax ledgers | India Compliance GST settings, HSN codes, tax templates | Configure and test before migration |
| Bill-wise outstanding | Opening invoices via the Opening Invoice Creation Tool | Load outstanding amounts by bill |
| Opening stock | Stock Reconciliation | Agree the valuation method first |
| Vouchers (history) | Not migrated by default | Keep Tally read-only for history and audit |
How a Tally to ERPNext migration works
ERPNext version 14 included a Tally Migration tool. We could not find it in the version-15 or develop branches of the ERPNext repository when we checked on Nov 12, 2026, so for a current ERPNext site, plan a designed migration instead of relying on it.
| Step | Work |
|---|---|
| 1. Freeze and clean | Pick the cutover date (ideally April 1, the start of the Indian financial year, or another month start). Clean duplicate ledgers and items in Tally. Reconcile banks and GST up to cutover. |
| 2. Export | Export masters (ledgers, parties, stock items, units, godowns) and closing balances from Tally, for example as XML or Excel, plus bill-wise outstanding and batch-wise stock. |
| 3. Transform | Map Tally groups to the ERPNext chart of accounts, split party ledgers into Customers and Suppliers, and prepare Data Import templates. |
| 4. Load masters | Use the ERPNext Data Import documentation (CSV or Excel, insert or update) for accounts, parties, items and warehouses. |
| 5. Load openings | Post GL openings against a temporary opening account, load bill-wise outstanding with the Opening Invoice Creation Tool, and load stock with Stock Reconciliation, as the ERPNext opening balance documentation describes. |
| 6. Reconcile | The temporary opening account should be zero; trial balance, receivables, payables and stock must match Tally at cutover. |
| 7. Go live and keep Tally read-only | Run the new year in ERPNext; keep Tally.ERP 9 available read-only for history and audit. |
A financial-year start is the cleanest cutover for GST and statutory reporting, because returns for the old year stay entirely in Tally. Mid-year cutovers work, but your accountant then reconciles GST across two systems for that year.
TallyPrime or ERPNext: a decision table
| If this is true for you | Lean towards | Why |
|---|---|---|
| Tally is used mostly by the accounts team and works well | TallyPrime | Familiar, fast, often a free upgrade |
| You have fewer than about five users and simple stock | TallyPrime | An ERP implementation is overkill |
| Production planning lives in spreadsheets beside Tally | ERPNext | Bills of materials, work orders and job cards in the same system as accounts |
| You need purchase approvals and role-based access across departments | ERPNext | Configurable workflows and permissions |
| You run several branches or warehouses with transfers and batch tracking | ERPNext (pilot first) | Multi-warehouse stock and batches in one site |
| Your CA and accounts team cannot spare time for a pilot month | TallyPrime for now | ERPNext needs real finance involvement to succeed |
| You want no per-user licence fee as you add users | ERPNext | GPL-3.0, no licence fee |
A realistic plan for an April go-live
| Phase | Work | Done when |
|---|---|---|
| Decide (2–4 weeks) | List what runs outside Tally today; score against the decision table | A decision to pilot ERPNext or upgrade to TallyPrime |
| Discovery (4–6 weeks) | Processes, users, GST setup, branches, history policy | Signed scope and mapping workbook |
| Pilot (6–8 weeks) | Masters, one month of transactions, GST returns prepared and reviewed by your CA | Accounts and operations agree the pilot works |
| Build and train (2–4 months) | Workflows, print formats, reports, user training by role | User acceptance signed off |
| Dress rehearsal | Full trial migration of masters and openings | Balances match Tally |
| Go live (April 1) | Close the year in Tally, load openings, go live | First month and first GST returns filed from ERPNext |
These durations are our planning ranges for a small to mid-sized manufacturer or distributor, not a promise. If you are still on Tally.ERP 9 without TSS, upgrading to TallyPrime first and moving to ERPNext later is a perfectly reasonable sequence. It keeps your compliance current while you plan properly.
Best for, and wrong choice when
ERPNext is the right move when
You are a manufacturer or distributor with operations spread across spreadsheets beside Tally, several users across departments or branches, production or batch tracking needs, and the willingness to fund training and a pilot month with your CA involved.
ERPNext is the wrong choice when
Tally is essentially your accountant’s tool, you have only a few users, or nobody can give the project time. In those cases TallyPrime is simpler and usually much cheaper.
Staying on Tally.ERP 9 without TSS is the wrong choice when
You are GST-registered and rely on Tally for e-invoicing, e-way bills or returns, because those features will not stay current without TSS.
Frequently asked questions
Is Tally.ERP 9 discontinued?
No. Tally says Tally.ERP 9 is not discontinued and will continue to work. What changed is that TSS renewal for Tally.ERP 9 licences is discontinued from August 16, 2026 (checked Nov 12, 2026).
Can I still renew TSS on Tally.ERP 9?
No. Tally says TSS renewal for Tally.ERP 9 has been discontinued; you need to upgrade to TallyPrime and renew TSS there.
Is the TallyPrime upgrade free?
Tally says customers whose TSS was active on or after November 9, 2020 are eligible for a free upgrade to the TallyPrime release available on their TSS expiry date. Others need a paid upgrade.
How much does TallyPrime cost?
Tally’s global pricing page lists the International licence at USD 630 for Silver (single PC) and USD 1,890 for Gold (multi-user), one-time with one year of TSS. India licences are a separate licence type; ask Tally or your partner for that price.
Does ERPNext support Indian GST?
Yes, through the open-source India Compliance app, which covers GSTR-1, GSTR-3B, purchase reconciliation against GSTR-2A and 2B, e-invoice and e-way bill integration. Some API-based features need a paid India Compliance account.
Is there a Tally to ERPNext migration tool?
ERPNext version 14 had a Tally Migration tool, but we could not find it in the current version-15 or develop branches. Plan a designed migration using Tally exports and ERPNext’s Data Import and opening balance tools.
When is the best time to move from Tally to ERPNext?
At the start of a financial year, ideally April 1, so the previous year’s GST returns and statutory reporting stay entirely in Tally.
