Customer retention software: types, tools and how to choose

Customer retention software helps a subscription business keep the customers it already has. For SaaS and apps it comes in four types: customer success platforms that guide account managers, cancel flow tools that make an offer when someone tries to leave, payment recovery tools that fix failed charges, and retention suites that combine several of these on your billing data. The right one depends less on features than on who does the work: your team, or software acting on its own.

TL;DR

• Customer success platforms (Gainsight, ClientSuccess) score accounts and tell your CSMs who to call. Best for high-value B2B accounts with a CS team. Priced on request.
• Cancel flow tools (ProsperStack, Chargebee Retention, Raaft) show a reason survey and an offer at the moment of cancellation. Usually priced by cancel sessions.
• Payment recovery tools retry failed charges and email customers. See best dunning management software.
• Retention suites (NoChurn, Churnkey, Paddle Retain, Recurly Engage) combine recovery, cancel flows and win-back, connected to your billing.
• Measure first. Split your churn into voluntary and involuntary before buying. The fix is different for each.

What is customer retention software?

Customer retention software is any tool whose main job is to stop paying customers from leaving, or to bring them back. It works on one or more of the moments where customers are lost:

Moment	What goes wrong	What the software does
Early life	The customer never gets value	Flags low activation, triggers onboarding help
Ongoing use	Usage drops, problems pile up	Health or churn score, alerts, playbooks
Payment	A card declines	Retries, recovery emails, card update page
Cancellation	The customer clicks cancel	Reason survey, matching offer, pause
After leaving	The customer is gone	Win-back emails, resubscribe prompts

Most subscription churn comes from two places: customers who decide to leave (voluntary) and payments that fail (involuntary). See involuntary churn and how to reduce customer churn.

What are the four types of retention software?

1. Customer success platforms

Built for teams of customer success managers. They pull data from your CRM, product and billing, compute a health score per account, and assign tasks (playbooks) to the CSM in charge. The software informs; people act.

Fits: B2B SaaS with high-value accounts and a CS team. Does not fit: thousands of low-priced subscriptions where nobody will call each customer. See customer health score.

2. Cancel flow tools

They replace the cancel button with a short flow: why are you leaving, here is an offer that matches your reason, confirm. Offers are usually a discount, a pause or a plan change. See cancel flow best practices and click-to-cancel rules.

Fits: self-serve subscriptions where customers cancel on their own. Watch: the cancel option must stay easy to find. Hiding it creates complaints, chargebacks and legal risk.

3. Payment recovery (dunning) tools

They catch failed renewals, retry at better times and email the customer a link to update their card. See dunning management.

Fits: every subscription business that bills cards. Failed payments are often the easiest churn to win back, because the customer did not decide to leave.

4. Retention suites

They combine payment recovery, cancel flows and win-back, sometimes with a churn score and chargeback handling, on top of your billing system. They act automatically on billing events instead of creating tasks for people.

Fits: SaaS and apps that want one tool for both kinds of churn, without a CS team doing manual outreach.

Gainsight

A customer success platform for CSM teams: configurable health scorecards, playbooks and renewal management. Gainsight sells two CS packages, Essentials and Enterprise, and says its CS pricing is moving to a value-based model based on ARR and number of customers managed. It does not cover failed payment recovery or a customer-facing cancel flow on the pages we reviewed. See NoChurn vs Gainsight.

ClientSuccess

Also built for CSM teams: SuccessScore, a weighted health score set up by your admins, Pulse, the CSM’s own rating of each account, and renewal forecasting. It integrates with Stripe, Salesforce and HubSpot. Pricing is on request. See NoChurn vs ClientSuccess.

ProsperStack

A cancellation flow specialist with wide billing support, including Stripe, Chargebee, Recurly, Braintree, Paddle, Maxio and Zuora. It also lists revenue recovery and winback campaigns. Priced by cancel sessions: Grow from $200/month for 50 sessions, Prosper at $750/month for 500 or more. See NoChurn vs ProsperStack.

Chargebee Retention

Formerly Brightback. A personalized cancel page with discount, pause, extension and plan change offers, closely tied to Chargebee Billing and also documented for Stripe and Recurly. Plans include a monthly allotment of cancel sessions, with fees above it. See NoChurn vs Chargebee Retention.

Raaft

A no-code cancel flow tool with coupons, pauses, plan switches and callback requests, for Stripe, Braintree, Recurly, Chargebee and Paddle. Its free plan covers up to 20 sessions per month and Basic is $79/month. Failed payments and win-back are not covered on the pages we reviewed. See NoChurn vs Raaft.

NoChurn

NoChurn is our product, a retention suite. It recovers failed payments (retries timed to the decline reason, AI-written emails you can review, a hosted card update page), runs a cancel flow with one offer per reason and a one-click cancel always visible, sends win-back emails at 30, 60 and 90 days by reason, scores churn risk from 0 to 100 at signup, and drafts chargeback replies for human review. It connects to Stripe, Chargebee, Recurly, Paddle, Braintree, the App Store, Google Play and more, or to any billing through the REST API.

Pricing: free until $300 MRR, then from $9/month up to $399/month at $500k MRR, custom above, every feature on every plan (your own email domain from $9). See pricing.

Honest limit: NoChurn is new and has no customer results to show. It does not replace a CS team’s account management for large B2B accounts.

Churnkey

A mature retention platform: customizable cancel flows, failed payment recovery with a payment wall, reactivation campaigns, analytics and an open-source React SDK with a headless mode. It supports Stripe, Chargebee, Maxio, Paddle and Braintree and prices by your average monthly churned revenue. See NoChurn vs Churnkey.

Paddle Retain

Formerly ProfitWell Retain. Recovery emails and retry timing, plus cancellation flows in the Paddle customer portal for Paddle Billing. Paddle says Retain is included at no extra cost for Paddle Billing customers; on other billing platforms it is sold on commission. See NoChurn vs Paddle Retain.

Recurly Engage

A low-code platform for in-app and web prompts across the subscriber lifecycle: cancel save surveys, payment failure prompts, onboarding, upsell and resubscribe, with A/B testing and SDKs for web, mobile and TV. Sold on annual contracts. See NoChurn vs Recurly Engage.

Baremetrics

Subscription analytics with two retention add-ons: Recover for failed payments and Cancellation Insights for cancel reasons and retention offers on Stripe. Useful if you already want its analytics. See NoChurn vs Baremetrics.

Which type do you need?

Your situation	Start with
Many failed payments, few cancellations	Payment recovery, or a suite that includes it
Customers cancel themselves in a self-serve flow	A cancel flow tool or a suite
Both voluntary and involuntary churn, no CS team	A retention suite
Few, large B2B accounts with CSMs	A customer success platform
You bill with Paddle	Paddle Retain first, since it is included
Mobile app billed through the App Store or Google Play	A tool that reads store notifications; cancellation itself stays with Apple and Google. See App Store cancellation retention.

How to choose customer retention software

1. Measure your churn split. Voluntary vs involuntary, by month. Use the churn rate calculator.
2. List your billing platforms. Remove any tool that does not connect to them.
3. Decide who acts. People (a CS platform) or software (cancel flow, recovery, suite).
4. Compare pricing at your size in a year. Sessions, churned revenue, commission and flat MRR bands give very different costs as you grow.
5. Check the cancel experience. One-click cancel must stay visible. A tool that encourages hiding it will cost you in complaints and chargebacks.
6. Test on part of your customers. Compare the same weeks, then keep one tool.

FAQ

What is customer retention software?

Software whose main job is to keep paying customers or bring them back: health scores and playbooks for CS teams, cancel flows, failed payment recovery and win-back campaigns.

What is the difference between a customer success platform and retention software?

A customer success platform helps people manage accounts: it scores health and assigns tasks to CSMs. Retention software in the narrower sense acts directly on customers, with retries, cancel offers and win-back emails, usually without a person in the loop.

Is a CRM enough for customer retention?

A CRM stores contacts and deals. It does not retry failed payments or show an offer when someone cancels. Many teams use both: the CRM for relationships, a retention tool for billing events.

How much does customer retention software cost?

It depends on the model. Customer success platforms are usually priced on request. Cancel flow tools are often priced by sessions, from free tiers to hundreds of dollars a month. NoChurn is free until $300 MRR and then from $9/month, flat by MRR.

Does retention software work without Stripe?

Yes. Many tools support Chargebee, Recurly, Paddle and Braintree. NoChurn also connects to App Store, Google Play and other platforms, or to any billing through its REST API.
