What should be in a WMS implementation contract?

The clauses most likely to predict downstream problems don't read as problematic from inside the buyer-only frame. The signal isn't in what looks aggressive on the page — it's in what specific contract language predicts about how a vendor will behave when implementation gets hard, and that signal is sell-side knowledge.

The contract patterns that predict trouble usually look reasonable.

Vague scope language that defers definition to "discovery" or "kickoff" — the contract doesn't commit because the vendor knows the actual scope will exceed what the buyer would sign for upfront. Customization-out-of-scope provisions that exclude the workflow modifications the vendor implied during the demo would be straightforward to support. Termination clauses that allow the vendor to walk if the project gets complicated but require the buyer to pay through completion if they want to walk for the same reason.

None of these are unusual. They appear in most WMS implementation contracts in some form. The signal isn't whether they're present — it's how they're scoped, what they're paired with, and what they predict about how the vendor will behave when the project gets hard. That signal is sell-side pattern recognition. It comes from having structured those contracts from the inside, having watched how each clause gets invoked when a project goes sideways, knowing which vendors use which clause patterns and what each pattern predicts about post-signature behavior.

A founder reviewing the contract from the buyer's seat sees standard commercial language. The patterns that would change the negotiation aren't visible from where they're sitting. The frame is the gap, and contract review run inside it produces a signed agreement that looked fine until the project got complicated.
