B2B marketing mix: valuing the contract, the service and the renewal risk.
Key distinctions
Three conditions before calculating.
Consolidated net price
The headline discount is only a start. Free items, credit notes, consulting days, service clauses, financing, penalties and payment terms must be included to reconstruct what the company genuinely collects.
Specific cost to serve
Pre-sales, integration, security, training, support and dedicated developments vary strongly by account. Diluting them into an average turns complex customers into false strategic accounts.
Risk-adjusted value
Future contributions must be weighted by the probability of renewal and by retention costs. A contract duration guarantees neither usage, nor expansion, nor future margin.
Method
Computing the defensible economic value of a contract
- 01Reconstruct the net price
Start from the tariff, then deduct every monetary concession and value the uninvoiced commitments; the calculation must be shared by sales, finance and operations.
- 02Assign the avoidable costs
Allocate to the account the costs that would disappear if the contract were not signed — acquisition, integration, infrastructure, support and specific governance.
- 03Project the renewals
Compute each future year separately with its margin, its probability of presence and its expansion costs; do not mechanically multiply ARR by an average duration.
- 04Test the sensitive clauses
Vary volume, discount, support load, payment terms and renewal; the negotiation must bear first on the parameters that reverse the contribution.
The expected value of two B2B contracts
Contract revenue is restated for discounts, account-specific costs and the probability of renewal over three years.
The €120k contract is worth less than the €105k one
The Atlas account signs €120k a year with an 18% discount. Its first-year cost reaches €53k and its annual probability of renewal 82%. The Boréal account signs €105k, costs €44k in the first year and renews with a probability of 90%.
Atlas: net price €98.4k, expected contribution over three years = 45.4 + 68.4 × 0.82 + 68.4 × 0.82² = €147.5k. Boréal: 61 + 75 × 0.90 + 75 × 0.90² = €189.3k.
Headline revenue must not drive commercial priority. Atlas must be renegotiated on the discount, the integration or the support before being classed as the more valuable account.
Acceptance conditions
What must be true to act.
- 01
All concessions are converted into comparable economic value.
- 02
Account-specific costs are separated from genuinely fixed costs.
- 03
Every future contribution is weighted by an explicit probability.
- 04
The clause to renegotiate is the one that most reduces economic regret.
Limits
What this analysis does not prove.
- A historical renewal probability can be poorly informative for a new offer or segment.
- Reference value, learning and access to a market can justify a less profitable contract, but must be quantified separately.
- The model does not replace the assessment of legal, credit or customer-concentration risk.
