This free customer success plan template is for customer success managers, account managers and the CS leads who approve their plans, in B2B and SaaS companies. One run builds one customer’s plan with the customer after signature and follows it through its first 90 days, counted from the kickoff. It starts with the contract, the stakeholders and discovery with the champion and the executive sponsor. Then it drafts two to four business outcomes, each with a measure, a baseline and a target, the milestones and adoption targets for the first 90 days, what your side will do and the risks. The CS lead approves the plan before the customer sees it, and the sponsor agrees it at the kickoff. Check-ins, a 30-day update and a 60-day check follow, then a 90-day review scores each outcome and resets the plan. Tasks appear for a first plan or a replacement plan, a missing sponsor, open points after the kickoff and a plan that is at risk at the mid-point.
A customer success plan, in this template, is the written plan for one customer after signature: the business outcomes the customer bought the product for, how each will be measured from a baseline, the milestones that lead there, who owns each step on both sides, and the risks. The customer’s executive sponsor agrees it, and it is scored and reset at each review, so it records what the customer achieved rather than what your team did.
Other plans sit around it. How customers are segmented and which playbooks they get is a decision for the customer success strategy checklist. Each quarterly business review is one meeting that scores the plan and updates it. Before signature, the seller and the buyer agree a mutual action plan for the deal itself, and the goals it records reach customer success in the sales to customer success handoff. Your own account plan for growing the account stays internal. The set-up project runs in the SaaS customer onboarding checklist or, for a large account, the enterprise customer implementation checklist, and an account that may not renew gets the at-risk customer checklist.

Eight phases take one customer’s plan from set-up about four weeks before the kickoff to the review about 13 weeks after it. Due dates count in working days from the kickoff date on the first task. The first task’s answers add a task to read the sales handoff for a first plan or to score the previous plan for a replacement, and a task to secure an executive sponsor when none is named. The CS lead’s approval in Phase 4 is the gate: Approved with changes adds a task to make them, and Not approved keeps the checklist halted, hides Phases 5 to 8 and adds a rework task. After the kickoff, a sponsor who has not agreed yet adds a task to settle the open points, and an At risk or Off track status at the 60-day check adds a recovery plan.
Start about four weeks before the kickoff. Record the customer, the kickoff date that every due date counts from and the people on your side, then gather what you already know before you speak to the customer.
Ask before you write. The plan rests on the customer’s outcomes in their own words, the measures they already report on and the people who will do the work, so hear from the champion and the sponsor before drafting anything.
Write the plan the sponsor will read: a few business outcomes, how each is measured, the milestones that lead to them and who owns each step on both sides. Keep it short enough to walk through in one meeting.
The CS lead checks the plan before the customer sees it: the outcomes are the customer’s, the targets are measurable and realistic, and everything your side commits to is within the contract and your team’s capacity. Nothing after the approval can be completed until it is given.
Applies only when the plan has not been turned down: a Not approved decision in Phase 4 hides Phases 5 to 8 until the decision is changed and the approval completed. The sponsor agrees the plan at the kickoff, and the agreed version is the one every check-in measures against.
Applies only when the plan has not been turned down in Phase 4. Work towards the first milestones and the first result the customer can see. Meet the champion on the rhythm you agreed and keep the plan’s dates current.
Applies only when the plan has not been turned down in Phase 4. Halfway through, read each measure against its target and decide whether the plan is on track. A plan that is slipping is easier to recover now than at the 90-day review.
Applies only when the plan has not been turned down in Phase 4. Score the plan with the sponsor and reset it for the next period. If the review takes place inside a quarterly business review, prepare the meeting with the QBR checklist and use these tasks for the plan itself.
The plan below is a worked example for a fictional customer: Fenmoor Foods, a food manufacturer with three sites, after buying a maintenance management platform from Harbourline Software, also fictional. The names and figures are invented to show the shape of a plan; use your customer’s own measures and baselines in yours. The live example checklist on this page is the same plan being built.
| Outcome | Measure and baseline | Target and date | Milestones on the way | Owners |
|---|---|---|---|---|
| Fewer hours lost to unplanned stoppages on the packing lines | Unplanned downtime on lines 1 to 4, from the site’s shift reports: 46 hours a month (July to October 2026) | 30 hours a month by the end of April 2027 | Planned maintenance for lines 1 to 4 loaded by day 20; engineers closing work orders on the platform by day 30; first downtime report from the platform by day 45 | Fenmoor: operations director (sponsor) and engineering manager. Harbourline: CSM and technical lead |
| Planned maintenance done on time at all three sites | Planned jobs completed by their due date: 71% at the first site, not measured at the other two | 90% at all three sites by day 90 | First site live by day 30, the second by day 50 and the third by day 70 | Fenmoor: engineering manager at each site. Harbourline: technical lead |
| Maintenance records ready for customer audits without a search | Time to gather the maintenance records for one audit: about two working days | Under an hour by day 90 | Asset register complete by day 25; history for critical assets loaded by day 40; a practice audit at day 80 | Fenmoor: technical manager. Harbourline: CSM |
| Adoption, a step towards the outcomes above | Engineers active on the platform each week: none of 38 licences before go-live | 32 of 38 by day 60 | First site’s engineers trained by day 14, the other two sites by day 45 and day 65 | Fenmoor: engineering managers. Harbourline: technical lead |
What makes the example work. Each outcome is something the sponsor is judged on, not a feature switched on. Each has one measure the customer already reports, a baseline taken before go-live and a target with a date. The milestones fall around the 30, 60 and 90-day points that the check-ins look at, and every line has an owner on the customer’s side as well as yours. Adoption is tracked, but as a step towards the outcomes rather than an outcome itself.
A plan the sponsor will read. Keep the agreed plan to a page or two and the task-by-task detail in the checklist. After each review, write the next period’s plan as a new version, approved and agreed like the first, rather than editing the old one, so everyone can see what was agreed and when. Keep it to this customer’s own figures and your own commitments: no other customer’s data, and no roadmap dates your product team has not approved.
Every plan runs the same eight phases, with due dates counted in working days from the kickoff date, so the set-up starts four weeks ahead and the 30, 60 and 90-day checks fall on time whoever owns the account. Move the kickoff and every date moves with it. See how a checklist runs.
The CS lead approves each plan before the customer sees it, and that approval step holds the kickoff and everything after it until it is given. Answers on the first task, after the kickoff and at the 60-day check add the tasks each customer needs, through conditional rules.
The Reports Grid shows each customer’s plan and how far it has got, and the Tasks Grid shows each CSM what is due this week. The customer’s champion can be invited as a Guest, and opens and completes only the steps assigned to them.
CheckFlow does not replace your CRM or CS platform, and it does not calculate health scores or read your product’s usage. It runs the same steps for every customer’s plan, with an owner and a due date for each, the CS lead’s approval before the customer sees it and a record of who did what and when.
Hand the customer’s goals over from sales with the Sales to Customer Success Handoff Checklist, run the set-up with the SaaS Customer Onboarding Checklist or the Enterprise Customer Implementation Checklist, and prepare each review meeting with the Quarterly Business Review (QBR) Checklist.

A customer success plan is a written plan for one customer that sets out the business outcomes they bought the product for, how each will be measured from a baseline, the milestones that lead there and who owns each step on both sides. The customer’s executive sponsor agrees it, and it is reviewed on an agreed rhythm and reset at each review. This template builds the plan with the customer after signature and follows its first 90 days.
Two to four business outcomes in the customer’s words; a measure, baseline, target and date for each; the stakeholders on both sides; milestones and adoption targets for the period; what your side will do, within the contract; the risks and dependencies, each with a mitigation; the check-in rhythm; and the date of the review. Record when and how the sponsor agreed it. The example on this page shows how the parts fit together for one customer.
The example on this page is a fictional plan for a food manufacturer that bought a maintenance platform. It has three outcomes, such as fewer hours lost to unplanned stoppages, each with a measure the customer already reports, a baseline, a target with a date, milestones around the 30, 60 and 90-day points and owners on both sides. Adoption is tracked as a step towards the outcomes, not as an outcome. The live example checklist shows the same plan being built.
The CSM writes it, and the customer’s executive sponsor agrees it, because the sponsor owns the outcomes and the budget. The champion helps shape it and owns much of the day-to-day work. In this template the CS lead approves the plan before the customer sees it, checking that the targets are realistic and that everything your side commits to is within the contract, and the sponsor’s agreement is recorded after the kickoff.
In the first 30 days, set-up, the first team live and one result the customer can see, such as a process running end to end. By day 60, more teams brought in and each measure read against its baseline to decide whether the plan is on track. At day 90, a review with the sponsor that scores each outcome and resets the plan for the next period. This template follows that shape, with an update to the sponsor at 30 and 60 days.
Check progress with the champion on a rhythm you agree with them, such as weekly or fortnightly while the first teams go live, and update the sponsor at least monthly. Score and reset the whole plan at a formal review: this template holds the first one about 90 days after the kickoff, and later ones can follow your quarterly business reviews. Review sooner when something big changes, such as a new sponsor or a missed milestone.
A mutual action plan belongs to the sale: the seller and the buyer agree the steps to signature. A success plan starts after signature and records what the customer will achieve with the product, and how. A quarterly business review is one meeting that scores the success plan and updates it. In CheckFlow they are three templates: the Mutual Action Plan Template, this one and the Quarterly Business Review (QBR) Checklist.
Find one before you draft the plan. Ask the champion who owns the budget and the results the product was bought for, and ask that person to sponsor the plan, even if they only join the kickoff and the reviews. Without a sponsor, nobody on the customer’s side can agree the outcomes or clear the blockers. In this template, answering Not yet on the first task adds a task to secure one, and if nobody will, it becomes the first risk in the plan.
Yes, as a Guest. Invite the customer’s champion to your CheckFlow team as a Guest and assign them their own steps, such as the discovery call, the baselines, the check-ins and the 90-day review, alongside your CSM. A Guest opens and completes only the tasks assigned to them, so the CS lead’s approval and your internal tasks stay out of their view. Share the agreed plan itself as a document.
