How do I control costs with T&M?

Set weekly or sprint-based hour caps, require detailed time reports, and define clear priorities so the team works on the highest-value items first. Monthly budget reviews help catch overruns early.

When is T&M better than fixed-price?

When requirements are unclear, scope will change frequently, or you need ongoing development without a defined end date. T&M avoids the overhead of constant change orders.

Time and Materials Pricing Explained

Pay for actual hours worked — the flexible pricing model for evolving requirements and ongoing development.

Time and Materials (T&M)

A pricing model where the client pays for actual hours worked at an agreed hourly or daily rate, with no fixed upper limit on total project cost.

Explanation

T&M is the most flexible pricing model — you pay for what you get, and the scope can evolve freely. This is ideal for ongoing development, R&D, and projects with unclear requirements. The risk is entirely on the client: there is no upper bound on cost, and misaligned incentives (the vendor profits from more hours) can lead to waste. Mitigation strategies include weekly hour caps, sprint-based budgets, and detailed time tracking with client access.

Bookuvai Implementation

Bookuvai offers T&M pricing for ongoing maintenance, support contracts, and consulting engagements. For new product development, we strongly recommend milestone-based pricing instead, as it aligns incentives better. T&M engagements include weekly time reports, and the AI PM flags any hours that seem disproportionate to output.
