When to turn your customer success software selection checklist into a scorecard
A checklist for buying customer success software should score evidence, price the whole contract and survive renewal. Here is when to rebuild yours for UK teams.
What to take away
- The Digital Markets, Competition and Consumers Act 2024 replaced much of the UK consumer protection framework, so renewal reminders and cancellation routes belong in the buying decision.
- A customer success software selection checklist works when every line carries an owner, a test and a cost.
- Score outcomes you can measure rather than features you can count.
- Price the whole contract, from implementation through to export.
- Rebuild the checklist as a weighted scorecard when two or more vendors clear every mandatory line.
- Re-run the checklist at renewal, not only at purchase.
Before you shortlist
Start with the problem rather than the product. Write down the retention outcome you need to change and the date it must move, then sort requirements into mandatory, weighted and worth having.

The selection checklist
Work through these questions in order. Write down each answer so a procurement colleague can challenge it later.
Selection checklist questions
- Which retention metric must improve?
- Which systems feed the platform?
- Which integrations are non-negotiable?
- What is the first-year cost ceiling?
- Who administers the platform weekly?
- What does leaving look like?
- Which retention metric must improve, and how will you baseline it this quarter?
- Which systems feed the platform, and who signs off each feed?
- Which integrations are non-negotiable, ranked by the manual work they remove?
- What is the ceiling on first-year cost, including implementation and training?
- Who administers the platform each week, and how much time can they give it?
- What does leaving look like, in export format, notice period and deletion evidence?
Ask for three cost lines in writing: implementation, overage above the contracted tier and renewal indexation. Implementation is priced against data sources and migration windows. Overage is charged per seat. Indexation often tracks CPI, which the ONS put at 2.5 per cent in the year to December 2024.
Scoring and weightings
Weight the mandatory lines before you look at any vendor, favouring evidence over presentation.
Worked example. Four criteria, weights sum to 100. Score each 0 to 5 and multiply weight by score. Maximum 500. Pass mark 350.
| Criterion | Weight | Score | Weighted |
|---|---|---|---|
| Retention metric test | 30 | 4 | 120 |
| Implementation and migration | 25 | 3 | 75 |
| Integrations and API limits | 25 | 4 | 100 |
| Contract terms and exit | 20 | 2 | 40 |
| Total | 100 | 335 |
335 falls below the 350 pass mark.
Fix your pass mark in advance, and share the weightings with the buying group so the arguments happen in week one.
The customer success software review methodology we follow separates vendor claims, reference evidence and product tests before any score is awarded. Without that separation, a weighted total is just arithmetic.
Evidence and due diligence
Ask for two references from customers with a similar data model. Ask those references what changed in the first ninety days after go-live.
Check who owns pricing and quoting. CPQ and revenue management platforms overlap with retention software where a renewal is priced, discounted and approved. Agree which system owns that step before signature.
If satisfaction scores sit inside your business case, how to improve customer retention and satisfaction gives you a route from survey results to actions the platform can track.
The Digital Markets, Competition and Consumers Act 2024 strengthened the CMA's consumer enforcement powers, so check any automated renewal or win-back messaging against the current rules. The subscription contracts provisions in Part 4 require a reminder notice before a renewal and a straightforward cancellation route. The CMA's guidance on unfair commercial practices covers misleading win-back messaging.
When two finalists look equal, the customer success software comparison methods on this site show how to keep both sides on identical evidence lines.
Common questions
How long should the checklist be?
Ten to fifteen lines is usually enough. Longer lists push real requirements into a summary nobody reads.
Should we score the software or the vendor?
Score both, on separate sheets. Product scores should come from tests and data; vendor scores from references and contract behaviour.
What if two vendors finish level?
Return to the mandatory lines and check the evidence behind each. A tie usually means a line was scored on a claim.
Do we need to repeat this at renewal?
Yes. Data models, integration limits and pricing move within a two-year term, and a short annual check costs less than a forced migration.
