How to pay affiliates: payout methods, timing, and taxes

Most founders pay affiliates one of four ways: PayPal, Wise, a direct Stripe transfer, or a manual payout run built from a CSV export. Which one is right for you depends on how many partners you have and where they live, not on which tool sounds most sophisticated. Hold every commission for a short window before you pay it, and collect a signed W-9 (or W-8BEN for partners outside the US) before the first payout goes out.

Getting this wrong is expensive twice over. Pay too fast, and a refund or chargeback that lands a week later comes straight out of your own pocket, because the commission is already gone. Skip the tax paperwork, and you are the one scrambling every January to reconstruct who you paid and how much. None of this is complicated, it just needs a system before you have 30 partners instead of 3. If you have not set up the program itself yet, start with how to start an affiliate program for your SaaS first; this post picks up once you have partners to pay.

The 4 ways founders actually pay affiliates

Almost every SaaS affiliate payout runs through one of these:

• PayPal — the default for a reason. Most partners already have an account, so there is nothing new to set up, and PayPal supports mass payouts to dozens of people at once. The tradeoffs: fees run 2 to 5% on international transfers, and PayPal can hold or freeze funds without much warning.
• Wise — the better option once you have partners outside the US. Real exchange rates, lower fees than PayPal on cross-border transfers, and a clean batch-payment tool. It asks for bank details instead of just an email address, so onboarding takes an extra step.
• Stripe transfers — the natural fit if you already track conversions through Stripe Connect. Partners set up a Stripe Express or Custom account, and you push payouts from the same dashboard where the commission was tracked. One system, one source of truth.
• Manual and CSV payouts — the simplest option at a small scale. Export approved commissions to a spreadsheet and pay through whatever bank transfer or check process you already use. Full control, zero new tooling, but it does not scale past 20 to 30 partners without eating a full afternoon each month.

Which method fits where you are today

You do not need to solve this for the program you will have in two years. Under 10 partners, pay manually from a CSV; it is genuinely faster than setting up automation. 10 to 50 partners, several outside the US, use PayPal or Wise, whichever your partners already use more. Past 50 partners, or if you are already running conversion tracking on Stripe, use Stripe transfers, since it removes a reconciliation step when the same platform tracks the conversion and sends the money.

Timing: hold payouts long enough to protect against refunds

A commission should never pay out the moment a conversion happens. Give yourself a holding period — 30 days is a reasonable default, and it should be at least as long as your refund window — before a pending commission becomes approved and eligible for payout. This is the single biggest thing that separates a program that survives its first refund wave from one that does not.

The math matters more than it looks. If you are paying 25% recurring commissions, a single refunded annual plan can be a real dollar amount to claw back after the fact — much easier to hold the commission pending for 30 days than to ask a partner to return money they already spent. Put the holding period in your terms up front, and partners will not be surprised by it.

Taxes: W-9s, 1099s, and VAT

This section is general information, not legal or tax advice. Talk to an accountant before you finalize your process — rules vary by country and change over time.

For US-based partners, collect a completed Form W-9 before you send the first payment. It gives you their taxpayer ID and confirms they are a US person for tax purposes. If you pay a US partner $600 or more in a calendar year, you generally need to issue them a Form 1099-NEC and file a copy with the IRS.

For partners outside the US, collect a Form W-8BEN instead. It certifies foreign status, and you typically do not issue a 1099 to a non-US partner for services performed outside the US, but you should still keep records of what you paid them.

If a partner is a business that invoices you, common in the EU and UK, they may need to add VAT to that invoice, or you may owe a reverse charge depending on both countries involved. This is genuinely one of the more country-specific parts of running a partner program, so get a real answer from your accountant rather than guessing.

Whatever methods you use, keep one simple record per partner: legal name, address, tax form on file, and total paid per calendar year. That one spreadsheet, or your payout tool's export, is what makes January painless instead of frantic.

A payout workflow you can run in an hour a month

1. Export commissions that have cleared their holding period and are marked approved.
2. Reconcile against any refunds or chargebacks since your last run, and remove or reverse affected commissions.
3. Batch-pay the remaining list through your chosen method — PayPal, Wise, Stripe transfers, or a bank transfer from your CSV.
4. Mark each commission paid in your tracking tool so partners can see their own payout history.
5. At year-end, pull your W-9 and W-8BEN records and totals to generate 1099-NECs for US partners you paid $600 or more.

RewardSpring will not pick a payout method for you — that decision is genuinely yours to make based on your partners and your bank. What it does do is keep commissions in a pending state until your holding period passes, let you review and approve every payout, and export an approved batch as CSV so you can pay however you already pay people. If your partner-facing pages need to look like part of your product rather than a third-party tool, a custom domain for your partner portal is a small touch that partners notice. Our docs walk through connecting Stripe and setting your first holding period.

Pick a payout method that matches your partner count and geography, not the fanciest option. Hold commissions for at least 30 days before they are eligible for payout so refunds do not come out of your pocket. Collect a W-9 or W-8BEN before the first payment, track what you paid each partner, and talk to an accountant about VAT if you are paying international partners who invoice you.
