Tally to Zoho to NetSuite: when each ERP actually fits

Every founder we work with eventually asks the same question: are we on the right ERP? The conversation is usually triggered by something specific. A new investor asking pointed questions about the chart of accounts. An auditor flagging a control gap. A consolidation that takes three weeks to produce. A monthly close that has slipped from 7 days to 15 because Tally cannot keep up with the volume.

Across the dozens of growth-stage Indian companies we work with, three ERP brackets cover the lifetime of almost every business. Knowing which bracket you are in, and when to plan the migration to the next one, is one of the few finance infrastructure decisions that genuinely matters over a multi-year horizon.

Bracket 1: Tally — up to roughly Rs. 50 crore of revenue, single entity, India-only

Tally Prime is the workhorse of Indian SME finance and there is a reason for that. It is cheap (the perpetual licence is under Rs. 30,000), the talent pool of Tally-fluent accountants is enormous, GST workflows are well-supported, and statutory compliance outputs are accepted by every Indian auditor without question.

Where Tally shines: single-entity Indian operations, transaction volume up to roughly 10,000 entries per month, statutory compliance, audit-friendly outputs. For a company doing Rs. 20 crore of revenue with a 25-person team, Tally is genuinely fine.

Where Tally breaks: multi-entity consolidation (the standard add-ons are clunky), multi-currency operations (technically supported, operationally painful), integration with modern tools (expense management, payroll, CRM, e-commerce platforms), management reporting beyond the basic outputs, user-level access controls with audit trails. The break starts to show somewhere between Rs. 30 and Rs. 50 crore of revenue, depending on operational complexity.

Implementation cost: effectively zero. Most companies are already on Tally. Annual maintenance and support runs Rs. 10,000 to Rs. 50,000 depending on the number of users and the support contract.

Bracket 2: Zoho Books — roughly Rs. 50 to Rs. 300 crore of revenue, multi-currency, decent multi-entity, GST-native

Zoho Books is the right answer for most Indian growth companies between Series A and Series C. GST workflows are native, multi-currency is built in, multi-entity is supported (via Zoho Books Premium), and the integration story with the rest of the Zoho ecosystem (Zoho People for payroll, Zoho Expense for expense management, Zoho CRM for sales) is meaningful.

Where Zoho shines: multi-currency operations for companies with USD or EUR revenue, multi-entity setups with two to four operating subsidiaries, integrations with payment gateways and Indian banks, a usable management reporting layer (custom reports, scheduled emails, dashboards), and an API that lets a small finance-engineering team build the integrations the company actually needs. The user-level access control and audit trail are materially better than Tally.

Where Zoho starts to strain: at five or more operating entities, the consolidation workflow gets heavy. At very high transaction volumes (over 30,000 to 50,000 entries per month per entity), performance degrades. At the point where the company needs an integrated procure-to-pay workflow with multi-level approvals, three-way matching at the line-item level, and a real fixed-asset register with disposal workflows, Zoho's coverage is shallower than the next bracket.

Implementation cost: Rs. 50,000 to Rs. 2 lakh for a clean implementation by a qualified partner, plus Rs. 50,000 to Rs. 4 lakh per year in licence fees depending on tier and user count.

Bracket 3: NetSuite or SAP Business One — Rs. 300 crore and above, multi-entity, multi-currency, integrated procure-to-pay, IFC-compatible

NetSuite and SAP Business One are the workhorses of mid-market Indian groups. Microsoft Dynamics 365 Business Central fits the same bracket. At the very top end, Oracle Fusion and SAP S/4HANA take over.

Where these systems shine: integrated procure-to-pay with line-item three-way matching, real fixed-asset registers with maintenance workflows, advanced inventory management for product companies, IFC (Internal Financial Controls) compliance with full audit trails, multi-entity consolidation with intercompany elimination workflows, advanced revenue recognition for SaaS, project accounting for services companies, multi-book accounting for groups with both Indian GAAP and US GAAP or IFRS reporting needs.

Where these systems become overkill: anywhere below Rs. 300 crore of revenue. The implementation cost, the licence cost, the consultant dependency, and the operational overhead of running a NetSuite or SAP instance are all justifiable above a certain revenue threshold and ruinous below it.

Implementation cost: Rs. 25 lakh to Rs. 1 crore depending on scope, plus Rs. 5 to Rs. 15 lakh per year in licence fees for a 25-to-100 user setup. The implementation timeline is 4 to 9 months, the change management requirement is heavy, and the post-implementation support is a recurring line item in the IT budget.

The three migration trigger events

Most ERP migrations are driven by one of three events, not by a planned roadmap.

M&A activity

An acquirer wants to consolidate the acquired company into their group ERP. Or an acquirer's diligence team finds that the target's Tally setup cannot produce the consolidated reporting they need. We have seen both. In the first case, the migration happens post-close on a 6-to-12-month timeline. In the second, the target spends 90 days pre-close moving from Tally to Zoho specifically to make the deal happen.

The lesson: companies considering a sale in the next 18 to 24 months should think about their ERP early. A Tally setup with manual workarounds is not, by itself, a deal-breaker. A Tally setup that cannot produce auditable multi-period reports in a format an acquirer's diligence team accepts is.

IPO prep

SEBI requirements for an IPO-bound company include three years of audited financials under Ind-AS, IFC compliance under Section 134(5)(e) of the Companies Act, internal controls testing, and management's report on the effectiveness of those controls. Tally cannot support IFC compliance in any meaningful way. Zoho can, with effort and external consulting support. NetSuite or SAP make it natural.

Companies that are 18 to 24 months from a possible IPO start moving from Zoho to NetSuite (or upgrading their Zoho deployment significantly with custom controls) as part of the IPO readiness program. Companies that have not done this work 12 months out from an IPO are signalling that the IPO is not actually 12 months out.

Founder fatigue with reconciliation

The least planned of the three triggers, but the most common. The founder or CFO is tired of explaining why three different reports show three different numbers. The monthly close keeps slipping. The audit findings keep growing. The board pack quality has plateaued.

The fatigue trigger is real but it is also the most dangerous reason to migrate. A migration triggered by fatigue rather than by a structural need is a migration that solves a process problem with a tool change. The new tool inherits the process problems, and 12 months later the same fatigue resurfaces with a different vendor. We push back hard on fatigue-driven migrations and try to fix the underlying process issue first.

The migration cost nobody plans for

ERP migrations consume finance team productivity in a way that almost no other infrastructure project does. The published implementation cost is the tip of the iceberg. The hidden cost is the 30 to 50 percent of the finance team's time, for 4 to 9 months, that goes into data migration, parallel running, exception handling, and training.

For a 5-person finance team migrating from Zoho to NetSuite, the realistic loaded cost of the migration is the published vendor cost plus another 50 to 80 percent in finance-team time. Plan for it explicitly, or watch the monthly close quality slip and the audit findings accumulate during the migration year.

How to pick at each stage

Below Rs. 50 crore, single entity, India-only: Tally. Resist the temptation to over-engineer.

Rs. 50 to Rs. 300 crore, multi-currency or multi-entity: Zoho Books. Implement properly with a qualified partner, set up the integrations early, and use the period-locking and audit-trail features from day one.

Rs. 300 crore and above, or IPO-bound, or M&A consolidator: NetSuite, SAP Business One, or Microsoft Dynamics. Plan the implementation as a 6-to-9-month project, with a senior project owner who is not also running the daily finance function.

The right ERP is not the most expensive one or the most familiar one. It is the one that fits the stage. The companies that get this right are the ones that do not migrate too early (and waste the implementation budget) and do not migrate too late (and watch their finance function calcify around tooling limitations).
