How to Build a SaaS Affiliate Programme That Generates Consistent Revenue
An affiliate programme turns satisfied customers and relevant content creators into a distributed sales team that generates trial sign-ups on commission. Done right, it produces 15-25% of new customer revenue at zero upfront cost. Done wrong, it generates low-quality sign-ups and administrative overhead. The structure, the commission design, and the recruitment strategy that works.
The Economics of Commission-Based Acquisition
A SaaS affiliate programme is an arrangement where external individuals — typically existing customers, content creators in the product’s niche, or complementary tool operators — receive a recurring commission for every paying customer they refer to the product. The economics work for SaaS specifically because of the subscription model: a recurring commission (typically 20-30% of the referred customer’s monthly subscription, paid monthly for the lifetime of the subscription) gives affiliates a financial incentive to refer high-quality customers who will stay long-term, not just customers who sign up and churn. The affiliate’s interest is aligned with the business’s: both benefit from the referred customer staying and paying. This alignment makes SaaS affiliate programmes more effective at generating high-quality customers than one-time commission programmes.
The Four Design Decisions That Determine Programme Success
Commission rate: 20-30% recurring is the minimum to motivate promotion
The commission rate must be high enough to motivate active promotion — not just passive link placement. For a $99/month SaaS product, a 20% recurring commission generates $19.80 per month per referred customer. An affiliate who refers 10 customers generates $198/month in passive recurring income. This is the level of commission that motivates an affiliate to create dedicated content, include the product in their recommendations, and actively mention it in relevant conversations. Commission rates below 15% rarely motivate active promotion; they generate passive link placements that produce occasional sign-ups but not a sustained acquisition channel.
Cookie duration: 60-90 days minimum for B2B products
The cookie duration determines how long after clicking an affiliate link a sign-up will be attributed to the affiliate. B2B purchase decisions for SaaS products with $50-200/month price points often take 2-4 weeks from first awareness to trial sign-up. A 30-day cookie duration misattributes a meaningful proportion of affiliate-driven conversions. SA recommends 60-90 day cookie durations for B2B SaaS affiliate programmes to ensure that affiliates are credited for the full value of their promotional activity.
Payment timing: pay after the trial-to-paid conversion, not at sign-up
Affiliates should be paid when a referred user converts from trial to paid subscription — not when they sign up for a trial. Paying at sign-up incentivises affiliates to generate trial sign-ups from low-quality, low-intent audiences. Paying at conversion incentivises affiliates to refer users who are genuinely likely to pay, because their commission depends on it. This is the design decision that most improves the downstream quality of affiliate-referred customers.
Tracking and transparency: give affiliates a dashboard with real-time data
Affiliates promote products they trust and can track. A dashboard that shows clicks, sign-ups, conversions, and commission earned in real time is both a trust signal and a motivation tool: affiliates can see the financial return on their promotional effort and optimise their activity based on what is working. SA builds affiliate tracking dashboards directly in Bubble.io using referral link generation, click tracking via URL parameters, and a simple affiliate portal that displays the affiliate’s metrics and pending commission balance.

The Three Affiliate Types That Generate the Best Results
Existing paying customers
The highest-quality affiliates are existing customers who genuinely love the product and already recommend it informally. They are credible to their audience because they are authentic users, not paid reviewers. Recruit them with a personal email at day 60 after sign-up: ‘We are launching an affiliate programme — given how you have been using [Product], I thought you might be interested in earning a commission for the referrals you are probably already making informally.’
Niche content creators and newsletter writers
Content creators who write for the target audience — blog authors, newsletter writers, podcast hosts, and YouTube creators in the product’s specific niche — are high-quality affiliate candidates because their audience trusts their recommendations and is pre-qualified as the product’s target user. Recruit by offering a free account and a structured review process alongside the affiliate commission.
Complementary tool operators
Founders or operators of non-competing tools that serve the same audience are natural affiliate partners. A project management tool and a time tracking tool serve the same user; neither competes with the other. A formal affiliate arrangement with a complementary tool generates consistent referrals from a captive, relevant audience and typically performs better than content creator affiliates because the referral context (a direct integration recommendation) is inherently high-intent.
Q: What tools should I use to run a SaaS affiliate programme?
For early-stage SaaS products (under $10k MRR), SA recommends building a simple affiliate programme directly in Bubble.io: generate unique referral links for each affiliate using a URL parameter (e.g., ?ref=affiliateid), track clicks and sign-ups using Bubble.io’s database, calculate commissions based on subscription status, and display affiliate dashboards in a dedicated Bubble.io page. This approach costs nothing in additional tooling and is sufficient for managing up to 50 affiliates. At larger scale, dedicated affiliate platforms (Rewardful, FirstPromoter, or PartnerStack) provide more sophisticated tracking, payment processing, and tax documentation management.
Q: How do I prevent affiliate fraud?
The primary fraud risk in SaaS affiliate programmes is self-referral: an existing customer signs up for a new account using their own affiliate link to earn a commission on their own subscription. Prevent this by: checking that the referred email address is not associated with the affiliate’s account or company domain; requiring a minimum of 30 days of paid subscription before commission is paid (which prevents sign-up-and-cancel fraud); and reviewing conversions from affiliates who generate unusually high trial sign-up volumes relative to their actual audience size.
Q: When is the right time to launch an affiliate programme?
After you have 20-30 genuinely satisfied paying customers and a trial-to-paid conversion rate above 15%. Launching an affiliate programme before these conditions are met generates affiliate-referred sign-ups that churn at the same rate as direct sign-ups — which means affiliates earn little commission, become discouraged, and stop promoting. The affiliate programme works best when it brings high-quality traffic into a product that is already converting and retaining users well. The programme accelerates what is already working; it does not fix what is broken.
