The questions to settle before you sign an ERP subscription and implementation contract in Australia.
0 / 14 completed
Use this checklist when you have a shortlist of two or three ERP options and draft quotes. Tick an item only when the answer is in writing: in the quote, the statement of work or the contract. A verbal assurance in a demo is not enough, because the contract usually says it replaces everything discussed before signing.
The scope and price items make quotes comparable, as explained in the quote comparison guide. The compliance items reflect Australian rules in force in 2026: Single Touch Payroll Phase 2 reporting, Payday Super from 1 July 2026, GST and BAS, Peppol e-invoicing and the Privacy Act. The contract items cover the clauses that cost most later: renewal uplifts, auto-renewal, SLAs and data export, discussed in the contract traps guide and the exit planning guide.
The contingency range is an illustrative planning figure, not an industry statistic. For a large or complex contract, ask a lawyer to review the terms before you sign; for tax treatment, ask your tax agent.
