How is an affiliate cookie window different from commission duration?
Short answer: The cookie window or attribution window defines how long after a referral click a visitor may be credited to an affiliate. Commission duration defines how long the affiliate may earn on an attributed customer's qualifying purchases or subscription invoices. A 30-day cookie window does not necessarily mean 30 days of commissions. A program can attribute a customer within 30 days and pay recurring commissions for 12 months, three invoices, one purchase or longer, according to its terms.
This distinction is essential for subscription SaaS businesses because customer acquisition and recurring billing occur on different timelines. For recurring reward mechanics, see our recurring affiliate commission tracking guide.
Compare the two settings side by side
| Question | Cookie or attribution window | Commission duration |
|---|---|---|
| What does it govern? | Whether a referral can be attributed to an affiliate | How many eligible purchases or periods earn rewards after attribution |
| When does the clock start? | Usually a tracked referral click or other defined touch | Often first conversion, signup or first paid invoice, depending on terms |
| Common units | Days after a click | Invoices, months, years, first purchase or lifetime |
| What happens after expiry? | New attribution is no longer credited under that touch | Further invoices no longer generate commission under that entitlement |
| Typical implementation risk | Browser blocking, consent, cross-device identity | Renewal tracking, refunds, plan changes and entitlement caps |
Rewardful's cookie window documentation states a standard 60-day default that can be configured per campaign. That is a documented Rewardful setting, not an industry-wide standard. Other platforms and individual affiliate programs may use different windows.
Example: a 30-day window with 12 months of rewards
Imagine Affiliate A sends a qualified prospect on January 1. The program has a 30-day attribution window and pays 20% of eligible subscription invoices for 12 calendar months after first payment. The prospect signs up January 20 and pays February 1. If the attribution rule is based on the January 20 signup, it may qualify within the 30-day window; the affiliate can then receive rewards on eligible invoices through the contractual commission term. The cookie need not remain present for every later renewal once the account is reliably attributed.
If the program instead requires the first payment to occur within 30 days of the click, the February 1 payment could fall outside the window. The trigger event matters. Publish whether attribution locks at signup, qualified lead, trial activation or first paid conversion. For a technical treatment of identity persistence, see cross-device affiliate tracking and trial-to-paid attribution.
Four common ways to define commission duration
- One-time reward: Pay once for the first qualifying invoice or milestone.
- Fixed number of invoices: Pay on the first three eligible paid invoices, even if billing dates vary.
- Fixed calendar term: Pay on eligible invoices during the first 12 months after a specified starting event.
- Uncapped recurring: Pay on each qualifying renewal while the customer and program remain eligible.
Rewardful's maximum commissions documentation shows how campaigns can pay on every eligible invoice or limit the number of invoices. Its campaign setup guide also discusses limiting commissions by payments or months. Confirm the currently available controls and plan in your own account before publishing a specific promise.
Persist attribution after the first qualifying event
A browser cookie is a useful short-term signal, not a durable financial ledger. When a referral qualifies, store the affiliate ID, referral click ID, customer or account ID, attribution timestamp, campaign ID and policy version on the server. Link the stable account ID to Stripe or Paddle customer and subscription IDs. Use this mapping for later eligible invoices, with appropriate consent and privacy controls.
Browser privacy restrictions, device switching, cleared cookies and consent choices can prevent a referral from being recognized. Do not imply that a longer cookie duration defeats browser restrictions. Consider server-side attribution with explicit identity reconciliation where lawful and technically justified. If your program uses coupon or partner-submitted lead attribution, define how those mechanisms interact with click-based windows.
Write a policy that prevents contradictory promises
Define the triggering touch, window length, last-click or first-click precedence, direct traffic rules, cross-device matching, conversion event, commission start date, duration cap, refund treatment and cancellation or pause rules. Decide whether a new affiliate click can overwrite an already attributed paying customer. For most recurring SaaS programs, reassignment should require a clear rule and audit trail rather than silently changing an established customer's affiliate.
Example policy language: "An eligible customer must create an account within 30 days of a valid referral click. Once approved, the referring affiliate earns 20% of eligible collected subscription revenue for the first 12 calendar months after the customer's first successful payment, subject to refund and fraud adjustments." This is illustrative wording, not a legal template or universal best practice.
QA scenarios before launching the program
- Click on day 1, convert just inside the attribution deadline, and convert just outside it.
- Sign up within the window but make the first payment after it.
- Switch browser or device between referral and signup.
- Pay a second invoice after the cookie has expired.
- Reach the last eligible invoice or month and verify no further reward.
- Pause and resume a subscription under both calendar and invoice-count caps.
- Process a refund and ensure it adjusts the original commission only once.
- Test competing partner clicks and manual attribution overrides.
Frequently asked questions
Does a 60-day cookie mean the affiliate earns for 60 days?
No. The 60 days can refer only to attribution eligibility. Commission duration is a separate campaign or program rule.
Do recurring commissions stop when a referral cookie expires?
Not necessarily. If the customer was already attributed and the program permits ongoing commissions, later qualifying invoices can still earn rewards.
Is a lifetime commission always better?
Not automatically. It may encourage partners but creates a longer-term liability. Compare gross margin, retention, refund risk and partner contribution before choosing the term.
