Most SaaS founders spend weeks debating commission rates, then spend 20 minutes on payout logistics. Then affiliates start asking why they have not been paid, why their tax form is wrong, or why a payment bounced.
Payout mechanics are not glamorous. They are the foundation of affiliate trust. Get them wrong and your best affiliates leave for a program that pays reliably.
This article covers the four decisions that determine how well your payout system works: payment method, schedule, thresholds, and tax compliance.
Payment methods: fees, reach, and friction
Every payment method involves a trade-off between cost, affiliate experience, and operational complexity. There is no universal best option. The right choice depends on where your affiliates are and how much you are paying them.
Stripe Connect
Stripe Connect is the default choice for SaaS programs that already use Stripe for billing. Setup is straightforward: affiliates create or connect a Stripe account, and you push payouts directly.
Fee structure:
- Standard: 0.25% per payout, minimum $0.25, maximum $25
- Instant (debit card): 1% or $0.50, whichever is greater
- Cross-border transfers: additional 0.25-1% depending on currency and destination
Stripe Connect works well for affiliates in the US, UK, Canada, and most of Europe. Coverage drops in Southeast Asia, Latin America, and Africa. If you recruit globally, Stripe alone will not cover your affiliate base.
One practical limitation: affiliates in some countries face friction during identity verification. Expect a 10-15% drop-off during onboarding if your affiliates are spread across emerging markets.
PayPal
PayPal reaches over 200 countries and is the payment method most affiliates already have. For programs with international affiliates earning under $500 per cycle, it is often the path of least resistance.
Fee structure for mass payments:
- Domestic (US to US): 2% capped at $1 per transaction
- International: 2% plus currency conversion spread (3-4%)
- Minimum payout: $1
The currency conversion markup is easy to miss. An affiliate receiving $300 in EUR from a USD account loses $9-12 to conversion alone. Communicate this clearly.
PayPal holds have caused problems for affiliate programs at scale. Accounts receiving large inbound volumes can trigger automated reviews and temporary holds. If you plan to pay 50+ affiliates per month from a single PayPal account, test this with a small cohort first.
Bank transfer (ACH / SEPA / SWIFT)
Bank transfer is the lowest-fee option for large, recurring payouts. It is also the slowest and the most operationally intensive if you do not automate it.
Fee structure:
- ACH (US domestic): $0.20-$1.50 per transaction depending on provider
- SEPA (EU): typically free or under €0.50 per transaction
- SWIFT (international): $15-$35 per transfer, recipient bank may deduct additional fees
Bank transfer is practical for affiliates earning $1,000+ per cycle. For affiliates earning $50-100, the transfer fee represents a meaningful percentage of payout. Set thresholds accordingly.
The main operational risk: incorrect account details. A SWIFT transfer sent to a wrong account can take 3-5 business days to return, assuming it returns at all. Implement a verification step where affiliates confirm their account details before the first payout.
Crypto
A small but growing subset of affiliates, particularly in countries with unstable currencies or restricted banking, prefer crypto payouts. Stablecoins (USDC, USDT) are more practical than BTC or ETH for this purpose since the value does not fluctuate between payout and withdrawal.
Fee structure:
- On-chain transfer: $1-5 depending on network congestion (ETH mainnet can spike)
- Layer 2 or Polygon: under $0.10 per transaction
- Conversion to stablecoin: 0.1-0.5% on most exchanges
Crypto payouts create accounting complexity. You need to record the USD value at time of transfer for expense reporting. Most accounting software does not handle this natively. Only offer crypto if you have the operational capacity to track it properly.
Which method to use
A practical starting point for most SaaS programs:
- US affiliates earning $100+: Stripe Connect or ACH
- EU affiliates: Stripe Connect or SEPA
- International affiliates earning under $500: PayPal
- International affiliates earning $500+: bank transfer
- Offer crypto only on request, not as a default
Payout schedule: when to pay
The schedule you choose affects affiliate motivation, your cash flow, and your ability to handle disputes. The three most common models are net-30, net-60, and real-time.
Net-30
Net-30 means affiliates earn commissions this month and get paid next month. It is the most common schedule for SaaS affiliate programs, based on our data from programs using RefCampaign.
It gives you enough time to:
- Verify that the referred customer has paid (not just signed up)
- Process refund requests before paying out commission
- Consolidate payouts into a single batch to reduce transfer fees
Net-30 works well when your affiliate contracts are clear about when the clock starts. Does net-30 mean 30 days after the referral? After the customer pays? After the trial ends? Ambiguity here creates disputes.
Recommended definition: commission is earned on the day the referred customer makes their first payment. Payout occurs on the 15th of the following calendar month.
Net-60
Net-60 gives you additional protection against refunds and chargebacks, but it creates friction with affiliates. A 60-day wait to receive payment is a meaningful ask, particularly for affiliates who are actively comparing programs.
Use net-60 if:
- Your product has a high refund rate in the first 60 days
- Your average contract value is high and chargebacks are meaningful
- You operate in a regulated industry with payment reversals
If you choose net-60, communicate it clearly at signup. Affiliates who discover it after they have already started referring will feel misled.
Real-time or weekly payouts
Some platforms market real-time or weekly payouts as a competitive advantage. For most SaaS programs, this creates more problems than it solves.
The risk: an affiliate refers someone who pays, you pay out the commission, then the customer requests a refund within your refund window. You have paid out a commission on a payment you no longer have.
You can handle this with a clawback clause, but enforcing clawbacks is operationally messy and damages affiliate relationships.
Real-time payouts make sense in one scenario: if your product has no free trial, no refund window, and immediate payment capture. In that case, the risk of paying before you have cleared funds is minimal.
For most SaaS companies, net-30 is the right starting point. As your program matures and your refund data stabilizes, you can adjust.
Minimum thresholds: protecting margins without demotivating affiliates
A minimum payout threshold prevents you from sending $12 payments that cost $8 to process. But if the threshold is too high, affiliates with small audiences give up before they see any return.
The math
For Stripe Connect or PayPal mass payments, the effective cost of a payout is $0.25-$2 depending on amount and destination. A $50 minimum threshold is rational: the fee represents under 4% of the payout.
For bank transfers, a $100-$200 minimum is more defensible given the $15-35 fixed cost on international wires.
Setting a $500 threshold is common in industries with high-value products but creates problems in SaaS where many affiliates earn $50-150 per month early in their tenure. An affiliate sitting at $48 with a $500 threshold has no visible progress and little reason to stay active.
What the data shows
Based on our data from SaaS affiliate programs on RefCampaign, programs with thresholds above $200 have 23% higher affiliate churn in the first six months compared to programs with thresholds at $50-100. The affiliates most likely to churn are those in the $50-150 monthly earnings range.
Recommended approach:
- Set the threshold at $50-100 for standard affiliates
- Allow affiliates to request manual payout below the threshold once per quarter (covers the occasional edge case without opening a flood)
- Increase the threshold for affiliates who have explicitly agreed to quarterly payouts in exchange for a higher commission tier
Threshold transparency
Publish your threshold in your affiliate agreement and in your affiliate dashboard. Affiliates should always know their current balance and when they will hit the threshold. Hidden thresholds are a common complaint in affiliate communities. They signal that a program is designed to withhold payments, not facilitate them.
Tax compliance: W-9, W-8BEN, and EU VAT
Tax compliance is the part of affiliate payouts that most founders defer until they get an IRS letter or a VAT audit. Getting ahead of it requires two things: collecting the right forms and keeping records.
US affiliates: W-9
Any US-based affiliate you pay more than $600 in a calendar year must provide a W-9. This form collects their name, address, and Taxpayer Identification Number (TIN), which is either a Social Security Number or Employer Identification Number.
You use the W-9 to issue a 1099-NEC at year end. The 1099-NEC reports non-employee compensation to the IRS. Filing deadline: January 31 for the prior tax year.
If a US affiliate does not provide a W-9, you are required to withhold 24% of their payments as backup withholding and remit it to the IRS. This is operationally painful. Make W-9 collection a mandatory step in your affiliate onboarding, not an afterthought.
Practical checklist for US affiliates:
- Collect W-9 before first payout
- Store W-9 securely (encrypted at rest)
- Issue 1099-NEC by January 31 to affiliates earning $600+
- File 1099-NEC with the IRS by January 31 (electronic) or February 28 (paper)
Non-US affiliates: W-8BEN
Non-US affiliates must provide a W-8BEN (individuals) or W-8BEN-E (entities). This form certifies that they are not US persons and exempts them from US withholding tax, assuming their country has a tax treaty with the US.
Most developed countries have US tax treaties. Affiliates in countries without treaties may be subject to 30% withholding on payments. This is rare but worth checking if you have affiliates in non-treaty countries.
W-8BEN forms expire after three years or when any information changes (address, tax status). Build a renewal reminder into your system.
You do not file W-8BEN forms with the IRS. You retain them for your records in case of audit. Keep them for at least three years after the affiliate relationship ends.
EU affiliates: VAT
If you have affiliates in the EU and your company is not EU-registered, VAT treatment depends on the affiliate's status.
If the affiliate is a business (B2B): the reverse charge mechanism applies. The affiliate self-accounts for VAT in their country. You do not charge or remit VAT. Request their VAT number and include it on your payout records.
If the affiliate is an individual (non-business): you may be required to register for VAT in their country if you exceed local thresholds. In practice, most SaaS companies operating with individual affiliates structure the relationship as B2B by requiring affiliates to operate as self-employed individuals or sole traders with a VAT number.
This is an area where a tax advisor familiar with EU digital services rules earns their fee. The rules vary by country and the stakes of getting it wrong are non-trivial.
UK affiliates post-Brexit
The UK left the EU VAT system in 2021. UK-based affiliates are treated separately from EU affiliates. If you pay UK-based affiliates for marketing services, you are not required to charge UK VAT if you are not UK VAT-registered, provided the services are B2B and the reverse charge applies. Individual UK affiliates are a grey area. Same principle as EU: require them to operate as self-employed or as a limited company.
Payout process checklist
Use this before each payout cycle:
Before calculating payouts:
- Verify all referred customers in this cycle have cleared their payment (no pending charges)
- Apply refund window: exclude commissions on customers who cancelled within your refund period
- Confirm affiliate tax forms are on file (W-9 for US, W-8BEN for international)
- Confirm affiliate bank details or payment method are current
Calculating payouts:
- Pull affiliate commission report for the period
- Apply any tier adjustments or bonus commissions
- Check each affiliate against the minimum threshold
- Flag affiliates approaching their first payout for review (are their details complete?)
Processing payouts:
- Batch US affiliates separately from international (different payment rails)
- Record USD value at time of transfer for accounting
- Send payout confirmation to each affiliate with a breakdown: referrals, commission rate, gross commission, any deductions, net payout
After payouts:
- Reconcile against your bank or Stripe ledger
- Update affiliate dashboard to show payment status
- Log any failed payments and follow up within 48 hours
- Archive payout records (you need these for tax purposes)
How RefCampaign handles payouts
RefCampaign automates the calculation side of this process. Every referred conversion is tracked, commission is calculated against your rate structure, and affiliates can see their pending balance in real time.
Payout processing integrates with Stripe Connect for direct payouts. For affiliates using other payment methods, you export a payout file and process through your preferred provider.
Tax form collection and 1099 generation are on the product roadmap. For now, you manage tax forms outside the platform.
If you want to see how RefCampaign compares to other platforms on payout features, the RefCampaign vs. FirstPromoter comparison covers the specifics.
Scaling payout operations
At 10-20 affiliates, manual payout processing is manageable. At 50+, it becomes a liability. The failure modes are predictable: a payment goes to the wrong account, a 1099 is missing, an affiliate is paid twice because their records were duplicated.
The solution is not more headcount. It is better systems. Automate the calculation. Automate the threshold check. Automate the tax form collection. Reserve human review for edge cases.
The affiliate ROI calculator can help you model the economics of your payout structure, including the impact of threshold levels and payment method fees on your effective commission cost.

Getting started
Payout mechanics are not the most interesting part of building an affiliate program. They are among the most consequential.
Choose a payment method that reaches your affiliates. Set a schedule that protects your margins without creating unnecessary friction. Set thresholds that are defensible on fee grounds but do not punish early-stage affiliates. Collect tax forms before the first payout, not after the IRS asks.
