Support deserves its own line. Clarify what is included as standard, what a premium tier costs, the response times you can expect and where the support team is based. When a system is central to daily admin, slow or costly support is a real expense measured in staff time, even if it never appears on an invoice.

Beyond hosting location and certification, a few further questions round out proper due diligence: how often is the system independently penetration-tested, what is the vendor's data breach notification process, and does the school retain the ability to export its full data set on request rather than being dependent on the vendor for access.
Spreadsheets are where many multi-academy trusts start, and for a single form entry they can just about cope. Run several schools from them and the cracks show quickly. Versions multiply, formulas break, and no one is quite sure which file is current. For a trust accountable to governors, the Department for Education and parents, that is a real risk rather than a minor annoyance.
Staff retraining is the part most often underestimated. A migration is not finished when the data lands; it is finished when the office can do its daily work confidently in the new platform. Plan sessions before go-live, give staff a safe practice environment, and name a few internal champions who can answer quick questions in the first weeks. A good provider supports this directly, so ask what onboarding and training a supplier such as Compass Education includes as standard rather than assuming it is extra.
