What is an In-App Referral Program?

An in-app referral program is a system built directly into a SaaS product that motivates existing users to refer new customers in exchange for rewards. It works by providing users with a unique referral link, code, or invite system that they can share with others.

When a referred person signs up and meets predefined conditions (e.g., becomes a paying customer), the referrer receives a reward, and sometimes the new user does too.

How a referral program works: step by step

1. Users sign up to your platform

Like any other SaaS, you want to keep growing your user base in any way possible. You will have your own ways to acquire new users, beyond the referral and affiliate marketing channels.

It is important for a referral program that you have users, and that your user base is growing.

2. For every user a referral link is generated

Once a new user joins, you send us the information about the user. This can be email and/or UID of the user. Once we receive this, we will generate a unique referral link for them.

They can already see it when they click on something you added in your app:

• Refer & Earn
• A little gift icon
• Or any other way, you can become creative.

Once people click on the button or CTA you have added, a pop-up opens that asks people to become your advocate.

The opt-in has 3 functionalities: you control the data you send to Reditus, you can see how many people actually joined the program, and they need to agree to your referral program terms.

3. Users like your product

For users to refer your product, they will need to like your product first. Once they do, make sure you notify them about your referral program. Some ideas on when to do this:

• When they just had their WoW moment
• When they received value out of your product
• When they upgraded their account
• When they renewed their subscription

4. Users refer your product

Users don't have to register anywhere else to copy the links and share them with their friends and network. Ways they can share their link:

• One-to-one basis
• Communities they are in
• Social media
• Newsletters they run
• Podcasts
• Blogs
• Or anywhere else your ICP is

5. Referral receives a benefit

When someone signs up via the referrer, you can give that person a benefit. Think about extra credits, an extra trial, a discount, or anything else.

You set the reward yourself. It should be something that gets people to sign up to your product.

6. User moves to paid

When people signed up, they come into your normal onboarding flow and some of them will convert into paid clients. For people who got referred, the conversion rate is often higher, as they also receive the benefit (a discount, for example).

When the user moves to paid, you receive a payment, monthly or annual.

7. Referrer receives a commission

A referral program is often a double-sided incentive, so the referrer receives something as well. Money is the best motivation for people to recommend you: think about a flat fee or a recurring commission, similar to an affiliate program.

Once this cycle is done, it repeats itself, which makes it a perfect growth loop.

Why SaaS companies use referral programs

• Low CAC: you only reward users when referrals convert.
• High trust: recommendations come from satisfied customers, making referrals more likely to convert.
• Scalable: every new customer has the potential to bring in more users.
• Built-in virality: referral loops create organic, compounding growth.

In-app referral programs vs affiliate programs

• Referral program: promoted by existing customers, with rewards that are often discounts, credits, or perks.
• Affiliate program: promoted by external partners (bloggers, agencies, influencers), with rewards that are typically commissions.

Best practices for running an in-app referral program

• Choose the right reward. SaaS credits, discounts, or feature access often work better than cash.
• Prompt at the right time, after a user has achieved value (e.g., completed onboarding, hit a milestone).
• Sharing should be effortless: copy-and-paste referral links, one-click email invites, or in-app widgets.
• Measure referral rate, conversion rate, and overall revenue impact, then optimize.

Examples of in-app referral programs

• A project management SaaS offering $10 credit to both referrer and referee.
• A B2B SaaS tool giving users 1 free month for every successful referral.
• A SaaS productivity platform that opens premium features after 3 successful referrals.
