Our 2026 engagement terms, published in full
Seven pages, and the only unusual one is the third.
Selwyn has published its 2026 engagement terms in full.
The third page sets the share of the fee weighted to the go-live date, and what happens to it when a program slips — including the cases where a slip is the client's and the share is unaffected. The rest is ordinary: scope, change control, intellectual property, data handling, notice.
They are published because every client asks the same question in the third meeting, and being asked what proportion of the fee rides on the date should not require a meeting to answer.
Two things changed from the 2025 version. The notice period for a paused program moved from thirty days to forty-five. The definition of go-live was tightened to exclude anything behind a feature flag, which had been ambiguous and was read generously by nobody.
Every client asks the same question in the third meeting. Now they can ask it in the first.
