How much does it cost an agency to prepare a tender bid?

1. What belongs in the bid cost?

Count the effort needed to assess, prepare, review and submit this specific response. Include reading the pack, checking eligibility, developing the delivery method, collecting case evidence, estimating the price, coordinating partners and obtaining internal approval. Add any required presentation, demonstration or sample work to the plan at the stage when it is expected.

Use an internal cost per hour consistently. A selling rate can be useful for a separate view of displaced fee-earning capacity, but it is not the same as payroll or fully loaded internal cost. Record how each rate was calculated. If your chosen cost already includes overheads, do not add those overheads a second time.

2. A worked example for a small agency

The following is a hypothetical estimate, not a market benchmark: initial assessment, 4 hours at £50 internal cost; strategy and technical response, 12 hours at £55; case-study preparation, 6 hours at £40; pricing and approvals, 5 hours at £60; independent review and submission, 4 hours at £45. The total is 31 hours and £1,580 of internal cost.

Assume another £250 for a specialist’s agreed input. That makes the example £1,830 before any additional costs not included in the chosen rates. If the same team then spends eight extra hours revising the response at an assumed £50 an hour, the estimate rises by £400 to £2,230. Replace every figure with your own workload, cost basis and supplier quotes.

3. Is that expenditure sensible for this opportunity?

Compare the bid investment with the realistic delivery contribution from the work you could actually receive. A multi-supplier agreement’s headline value is not necessarily revenue available to one agency. The contract value is also not its profit. Separate delivery costs, third-party spend, recurring commitments and any uncertainty about orders before comparing the figures.

Do not invent a probability of winning to make the calculation work. If you have consistent historical records, document what comparable bids mean and how uncertain the sample is. If you do not, use a decision range: what is the maximum spend the agency can justify given the opportunity’s fit, accessible evidence, capacity and commercial terms? That is a management judgement rather than a forecast.

4. Approve the work in stages

Set an initial assessment allowance, then decide whether to release time for the full response. A practical internal gate might require a verified response route, a viable timetable, no unresolved mandatory capability gap and an agreed pricing owner. Those are suggested working checks; the buyer’s stated requirements remain separate.

Assign one person to record estimated hours, actual hours and changes. If an amendment adds a demonstration or a partner cannot supply evidence, revisit the decision while there is still time to act. Work already spent is a record of cost, not a reason to continue when the remaining response is no longer viable.

5. What should you record after the result?

Capture the actual effort by role, external expenditure, stage reached and the buyer’s feedback where available. A loss does not by itself show that the decision to bid was wrong; a win does not prove that the preparation process was efficient. Review which assumptions changed and which reusable evidence would have reduced avoidable effort.

Use the same definitions across future bids. Over time, your own records can improve estimates for similar response formats. Keep the work of preparing the bid separate from the cost of delivering the contract, so that both decisions remain visible.
