Costs & performance

When delivery time varies, what should your price reflect?

A practical way to examine the work behind the fee, without mistaking a simple margin for net profit.

Compare like with like

Two jobs with the same fee may consume very different amounts of time. Start with completed work of a similar type. Record the quoted scope, actual delivery hours, direct expenses and the changes requested along the way. Separate unusual one-off problems from a repeated pattern.

Make the assumptions explicit

Illustration only: a £2,000 engagement with £800 of direct costs leaves £1,200 before overheads and other costs. If delivery takes 20 hours, that is £60 of contribution per delivery hour. At 40 hours it is £30. Neither figure is a salary rate or net profit. It is a lens for examining delivery effort.

Look beyond an average

An average can hide the work that repeatedly overruns. Compare a straightforward job with a demanding one. Ask whether the difference comes from unclear inputs, extra revisions, waiting for approvals or a genuinely different service. Price, scope and delivery design should be considered together.

Turn the finding into an agreement

Use what you learn to clarify what is included, which inputs are needed and how changes will be agreed. A useful pricing conversation may concern the scope and process as much as the headline fee. These are general commercial considerations, not a recommendation for a particular business.

One practical action

Review three comparable completed jobs. Identify one scope assumption that should be clearer in your next proposal.
