Switching accounting software is a finance project, not an IT one. The aim is that on go-live day the new system opens with the same trial balance, the same customer and vendor balances, the same stock and the same tax position as the old one, and that the old records stay available for audit. This engagement covers the move end to end, between any two systems where the source can export and the destination can import.
When this service is typically required
- Moving from Tally or desktop software to cloud accounting such as Zoho Books
- A group, investor, lender or overseas accountant standardising on QuickBooks, Xero or Tally
- Consolidating accounting and payroll on one suite, such as Zoho Books and Zoho Payroll
- Outgrowing Excel books, Busy, Marg or an older ERP
- A previous migration that left balances, open items or tax ledgers that do not agree

Deliverables
Cutover plan, field mapping workbook, cleaned master data, import files, migrated data in the destination, go-live reconciliation pack with control totals and differences explained, sign-off note, and an archive of the old system.
Information and documents generally required
Access to the destination software, exports or access for the source software, trial balance and ageing as at the cutover date, stock statement, tax registrations and recent returns, bank statements for reconciliation, and for payroll, employee data, salary structures and year-to-date registers.
Engagement process
Client responsibilities, assumptions and reliance
The migration is carried out from the data and access the client provides and relies on its accuracy and completeness. The source period is to be closed and not altered after cutover without notice. Subscriptions and licences for both systems remain the client's responsibility, and the client signs off the go-live reconciliation before the old system is locked.
Scope exclusions
Correction of historical accounting errors beyond what the migration requires, custom software development, third-party integrations not supported by the destination, and audit or certification of the migrated figures are separate scopes.
Frequently asked questions
Which accounting software can you migrate between?
The common routes are Tally to and from Zoho Books, QuickBooks Online to and from Zoho Books, Xero to and from Zoho Books or QuickBooks, and payroll to Zoho Payroll. More generally, any software that can export data and any destination that can import it can be handled, including Busy, Marg, Sage and Excel books.
Do you use automated tools for migration?
We use in-house migration mapping and validation templates for each source and destination, and the destination software's own import functions. Every stage is checked with record counts and control totals rather than at the end.
Will my GST, VAT or sales tax data be correct after migration?
Tax registrations, rates and codes are set up in the destination before data is imported, and tax ledgers are reconciled with the source and the returns filed as part of the go-live checks.
Can you migrate in the middle of the financial year?
Yes, with a month-end cutover. Either current-year transactions are migrated or a bridge reconciliation is kept so that statutory and tax auditors can follow the year across both systems.
Do you need access to the old and new software?
Access to the destination is needed for imports and checks. For the source, exported files are often enough; with your permission we can extract them ourselves.
Do you also handle bookkeeping after the migration?
Where required, ongoing accounting and reconciliation can be taken up as a separate engagement after go-live, for Indian and overseas businesses.
The routes, depth of history, cutover date, responsibilities and timelines are agreed in an engagement letter before commencement.
