The clauses that actually matter
- The subject of the contract, described concretely, what you're delivering, not just "consulting services".
- Delivery deadlines for each stage, not just one final deadline.
- Payment terms: advance, due dates, what happens if payment is late.
- The scope-change process: how additional work gets approved and billed.
- Termination conditions, for both parties, not just the client.
Why they often get skipped
The pressure to start work quickly means these clauses get cut "so we don't overcomplicate things". Those exact clauses are the ones that prevent conflict when something doesn't go according to plan.
The signature matters too
A well-written contract that isn't signed correctly has zero legal value all the same. A digital PAdES signature applied directly to the document solves that without printing anything.
Bottom line
A good contract doesn't prevent every problem, but it gives you a clear framework when a disagreement comes up. The five clauses above are the minimum, not the maximum.
