What is the difference between Group Company and Merging Company Data in Tally?

Group Company creates a consolidated reporting view across separate companies without altering underlying data files. Merging Company Data permanently combines masters and vouchers from two separate Tally files into a single unified company file via XML export/import.

What is the step-by-step SOP to merge two Tally companies via XML?

Phase 1: Backup both companies and align F11 features. Phase 2: Export Masters (List of Accounts) and Transactions (Daybook) as XML from Source Company. Phase 3: Open Target Company > Import Masters (Combine Opening Balances) > Import Transactions.

How do I prevent voucher numbering conflicts when merging Tally data?

Ensure voucher numbering series do not overlap between the two companies. Enable 'Retain Original Voucher No.' or create distinct voucher types (e.g. Sales-BranchA and Sales-BranchB) before merging.

How to Merge Two Tally Companies Data (Complete SOP)

Quick Answer: How to Merge Two Tally Companies into a Single File?

To permanently merge two Tally companies: (1) Take full backups of both companies. (2) From Source Company, export Masters (List of Accounts) and Transactions (Daybook) to XML format. (3) Load Target Company, go to Import > Masters (select 'Combine Opening Balances'), then Import > Transactions.

Always import Masters XML before Transactions XML to prevent missing ledger errors.
Group Company is recommended if you only need consolidated financial reports.
Enable 'Retain Original Voucher No.' to prevent voucher numbering sequence conflicts.
Run Alt+Y > Repair in Tally Prime if duplicate GUID or master errors occur during import.

Decision Guide: Group Company vs Permanent Data Merge

1. Group Company (Reporting Only)

Keeps individual company files completely separate. Generates consolidated Profit & Loss, Balance Sheet, and Trial Balance reports. Ideal for separate branches or sister concerns with different GSTINs.

2. Permanent XML Data Merge

Combines all masters, ledgers, and transactions into a single Tally company file. Recommended when consolidating multiple legacy company files under the same GSTIN into a unified Tally Prime database.

3-Phase Standard Operating Procedure (SOP) to Merge Tally Data

Phase 1: Backup & Feature Alignment

Take a full data backup of both companies. Align F11 features (GST settings, inventory, multi-currency) between source and target companies.

Phase 2: Export Masters & Daybook from Source Company

Open Source Company. Go to Display > List of Accounts > Alt+E (Export) > XML format to export Masters. Go to Display > Daybook > Set period (Alt+F2) > Alt+E > XML format to export Transactions.

Phase 3: Import into Target Company

Open Target Company. Go to Import > Masters > Select XML path > Choose 'Combine Opening Balances'. Then go to Import > Transactions > Select Daybook XML path.

Phase 4: Post-Merge Data Verification

Compare Trial Balance and Daybook totals between merged target company and source files. Run Alt+Y > Repair if any orphan vouchers or duplicate GUID errors appear.
