AI implementation: fixed price or time and materials?

A fixed price for AI implementation needs an agreed scope and assumptions. With hourly billing, the buyer needs work approval rules, a record of completed tasks and spending controls. Neither approach removes uncertainty about data or integrations. Identify those questions before work starts.

At Syntalith, scope, price and timing follow process assessment. Our implementation offer describes a fixed quote for agreed work. If another supplier proposes hourly billing, ask how it will report completed work and obtain approval for further spending.

What each arrangement covers

Include tools and operating costs in both proposals. A fixed development price does not fix model charges when case volume grows. The AI agent cost guide explains that separation.

Resolve a specific unknown before quoting

Suppose a project should save quote drafts in a CRM, but access to the required object is unconfirmed. The team can test access and a sample write before quoting the integration.

Ask the supplier to name the uncertainty, explain the check and state the decision following a failed attempt. If it proposes a separate paid pilot, define the stage output and which elements remain useful for subsequent development.

A scope change record

Distinguish correcting behavior that fails an agreed requirement from adding a new feature. A shared brief and decision record help.

Calling a change small does not establish its effort. A second mailbox might require one connection or separate permissions and acceptance work.

Before selecting a supplier

For a fixed quote, check exclusions and what happens when assumptions change. For hourly work, identify who can assign tasks, the spending threshold requiring further approval and the report format. Agree acceptance, handover and maintenance in both cases. Bring Syntalith a list of unresolved questions so we can identify what needs checking before a fixed quote.
