Best Multi-Company ERP Software (2026)

It is ERP software built to run more than one legally distinct company within a single installation or account, keeping each company's financial data, GST registration and statutory reports separate, while sharing the same underlying system and, often, master data like a common item catalogue or customer base. It also typically supports inter-company transactions — one group company invoicing another — with proper accounting on both sides.

• Separate ledgers per company — no bleed of one entity's transactions into another's books
• Inter-company transaction support — invoices and journal entries that post correctly on both sides
• Consolidated group reporting — a combined view for management without merging statutory books
• Per-entity GST and statutory compliance — since each company files independently
• Shared master data option — common item or vendor lists where useful, without forcing it
• Role-based access by company — staff at one entity should not see another's financials by default
• Audit trail per entity — critical for statutory audits conducted separately per company

Confirm the system genuinely separates statutory books per company for audit and GST filing purposes — some 'multi-company' claims are really just tagging within one shared ledger, which auditors will flag. Ask specifically how inter-company transactions and eliminations are handled for consolidated reporting, and whether the software supports different financial years or accounting standards if your group has entities with different requirements.

Ask the vendor to demonstrate an inter-company transaction end to end — an invoice raised by one group company to another — and show the resulting entries in both companies' books. Request a sample consolidated report and check whether it can be filtered back down to entity level cleanly. Get clarity on licensing: some vendors charge per company, which can make a growing group's costs rise faster than expected.
