Affiliate program launch checklist: 30 items for SaaS

An affiliate program launch checklist for a SaaS product has about 30 items in six groups: terms, tracking, payouts and tax, partner experience, recruitment, and measurement. In our illustrative estimate the whole list takes around 33 hours of work spread over three to four weeks, and the order matters more than the speed: write the terms first, prove tracking with a real test purchase second, and recruit partners last, once a click can be followed all the way to a commission. Recruiting before tracking works is the most expensive mistake, because the first partners are the ones most likely to notice a missing commission and the least likely to give you a second chance. Below are all 30 items, a time table, the order, and the test transactions to run before you invite anyone.

How to use this affiliate program launch checklist

Each group below has five items. Each item is phrased as something you can verify as done or not done, not as advice. Work through the groups in the order given in the section on sequencing, because later groups depend on earlier ones: you cannot write a partner FAQ before the terms exist, and you cannot measure conversion before tracking works.

The time estimates are illustrative. They assume one person who knows the product, has access to Stripe and the website, and uses an affiliate platform rather than building tracking from scratch. A team with a complicated checkout, several plans in different currencies or a legal review step will take longer. Use the estimates to plan the order and the calendar, not as a promise.

Group 1: Terms (items 1–5)

Terms come first because every other group refers to them. The tracking setup needs the cookie window, the payout setup needs the minimum and hold period, and the partner FAQ needs all of it.

1. Commission rule written as one line: the rate or amount, what it is calculated on, and how long it lasts, for example "20% of each paid invoice for the first 12 months."
2. Cookie window and attribution model stated: for example "60 days from the last click; last touch; a code entered at checkout counts as the most recent touch."
3. Hold period matched to your refund policy: with a 30-day money-back guarantee, a 30-day hold before a commission becomes payable.
4. Minimum payout, schedule and methods stated: for example "$50 minimum, paid monthly by PayPal or Wise; balances below $50 roll over."
5. Prohibited methods and the disclosure rule written down: no brand-name bidding, no coupon sites, no self-referrals, and a requirement to disclose the commission clearly and close to the link, as the FTC describes for affiliates [1].

Before you move on, run the commission arithmetic for your own plan. On a $49 monthly plan at 20% for 12 months, each invoice pays $9.80. If your monthly churn is 5%, the expected number of paid invoices in 12 months is (1 − 0.95¹²) ÷ 0.05 ≈ 9.2, so a referred customer is worth about $90 to the partner and about $450 to you over that period. If that payout is more than you would pay to acquire a customer through other channels, change the rate or the duration now, before anyone has seen it.

Group 2: Tracking (items 6–10)

Tracking is the group to be most thorough about. Everything a partner experiences later depends on a click turning into a commission without manual work.

1. Tracking script installed on every page partners may link to, including blog posts and the pricing page, not only the home page.
2. Checkout passes the referral id to Stripe: when your server creates the Checkout Session, it sets client_reference_id from the referral cookie. Stripe documents this field as a reference for reconciling the session with your own systems, up to 200 characters [6].
3. Personal coupon codes set up for partners as promotion codes, so a purchase with a partner's code is attributed even without a click.
4. A full test purchase run in test mode: click a test partner link, sign up, pay, and confirm the commission row appears with the right amount.
5. A refund test run: refund the test invoice and confirm a negative row for the same amount appears.

If the coupon test uses a discount, check the base rule you wrote in item 1. A 20% off code turns a $49 invoice into $39.20, and 20% of that is $7.84. If your terms say commission is on the amount paid, the row should be $7.84, not $9.80. This is exactly the kind of mismatch that is cheap to find now and expensive to explain later.

Group 3: Payouts and tax (items 11–15)

Partners judge a program by its first payout. Decide how money moves before you owe any.

1. Payout method chosen and the account ready: PayPal Payouts lets a business pay many recipients by email, phone or PayPal ID [4]; Wise lets a business create up to 1,000 payments from one CSV or XLSX file [5].
2. Payout day fixed, for example the first week of each month, and written in the terms.
3. Tax forms collected before the first payout: a W-9 from US partners and a W-8BEN from non-US individuals, which the IRS says foreign individuals give to the withholding agent or payer [3].
4. Year-end reporting planned: US payers generally report payments of $2,000 or more to a non-employee on Form 1099-NEC for payments made after December 31, 2025 (the threshold was $600 before) [2]. Ask your accountant how this applies to you.
5. A rule for disputed or fraudulent commissions written down: what is held, who reviews it, and how the partner is told.

Run one more piece of arithmetic here: how long a new partner waits for their first payout. With a $50 minimum and a 30-day hold, a partner with a single $9.80 customer crosses $50 after the sixth invoice ($9.80 × 6 = $58.80), and that invoice becomes payable 30 days later, so about seven months after the first referral. A partner with five customers in the first month earns $49.00 in that month, just under the line, and crosses it with the second month's invoices. Say on your partner FAQ how many referrals a typical first payout takes, so nobody wonders whether something is broken.

Group 4: Partner experience (items 16–20)

This group decides whether partners who sign up actually start promoting. Most of it is writing.

1. A public program page that shows the terms from group 1 in plain text, one fact per line, with a sign-up button.
2. A short partner FAQ: how attribution works, when payouts happen, how many referrals a first payout takes, what is not allowed.
3. Ready-to-use assets: product screenshots, a logo pack, a 50-word and a 150-word product description, and two or three angles that work for your product.
4. A welcome email that gives the partner their link, their code and the one thing they should do first.
5. A named contact or support address for partner questions, with a response time you can keep.

If you use RelayWonder, the white-label partner portal on your own subdomain covers the mechanics of item 16 and part of item 19: a program page with an earnings calculator based on your real commission terms, sign-up that applies automatically, and a partner area with links, campaigns and earnings. Approval emails link to the portal when it is live. You still write the FAQ, the assets and the angles, because those are about your product.

Group 5: Recruitment (items 21–25)

Recruitment comes last in the order but takes the most time. Start with a short list and a high bar rather than a long list and a template.

1. A list of your existing happy customers who create content or run communities, invited first and personally.
2. A list of 30 to 50 creators, newsletters and blogs that already write about your category, each with a reason they would care.
3. A personal outreach email per person that names something specific they published and explains the offer in two sentences.
4. A follow-up plan: one or two follow-ups a few days apart that stop when the person replies.
5. An approval rule: who approves applications, within how many days, and what gets a partner rejected.

Two practical notes. Send outreach from a real person's mailbox, not a no-reply address, because replies are the point. And do not invite your outside list until the tracking tests in group 2 pass; the first outside partners are the ones whose experience you will hear about. RelayWonder's Hunter can build the outside list from web, YouTube and Reddit searches, score candidates with a reason, and send outreach from your own mailbox with follow-ups that stop on reply, but the bar for who is a good fit is still yours to set.

Group 6: Measurement (items 26–30)

Set up measurement before the first partner joins, so the first month's data is usable. Five numbers are enough to start.

1. Active partner rate: the share of approved partners who sent at least one click in the last 30 days.
2. Clicks to signups conversion per partner, so you can see who sends interested visitors.
3. Revenue and commission per partner from invoices, not from clicks.
4. Share of customers attributed through coupon codes versus links, which tells you how much the codes are worth.
5. A monthly review date: look at the numbers, pay out, and change one thing.

Resist adding targets you cannot justify yet. You will not know what a good conversion rate for your partners is until you have a few months of your own data, and borrowed benchmarks from other products mislead more than they help. The first goal is just to make sure each number can be computed.

How long each group takes and in what order

The table gives an illustrative estimate per group and the recommended order. The order puts dependencies first: terms feed tracking and payouts; tracking must pass before recruitment; measurement is set up before the first partner so nothing is lost.

At about 10 hours a week alongside other work, 33 hours is three to four weeks. A practical calendar is: week 1, terms and tracking, ending with the test purchase and refund passing; week 2, payouts, tax, partner experience and measurement; weeks 3 and 4, recruitment, starting with existing customers. Recruitment is not finished at the end of week 4; it continues as a weekly habit. What is finished is the program: everything a partner needs works.

Common launch mistakes

• Recruiting before tracking is tested. The first missed commission costs more trust than any later bonus recovers.
• Terms with "up to" rates and no duration. Partners and AI assistants will repeat the most generous reading.
• A hold period shorter than the refund window, which means paying commission on customers who then get their money back.
• A minimum payout so high that a typical partner waits most of a year.
• No coupon codes. Partners on podcasts and video lose most attribution without them.
• Collecting tax forms only when the first payout is due, which delays the payout partners have been waiting for.
