What "in-house" actually means
An in-house affiliate program means there's no third party between you and the merchant. You sign up directly with the brand. Tracking, payment, dashboards, and dispute resolution are all handled by the merchant (using affiliate-management software like Tapfiliate, Refersion, Rewardful, FirstPromoter, or PartnerStack — but white-labeled under the merchant's brand, so you experience it as "the merchant's program").
Concrete examples of in-house programs you've probably heard of:
- Amazon Associates — run entirely by Amazon, no network involvement.
- ConvertKit's Creator Network — direct from ConvertKit, 30% lifetime RevShare on referred users.
- Shopify Affiliate Program — direct from Shopify, applied through their site.
- Bluehost's affiliate program — direct from Bluehost, $65–$130 per signup depending on tier.
- ClickFunnels Affiliate Program — direct, 30% recurring lifetime.
- Teachable's program, Thinkific's program — direct from each platform.
Why merchants run in-house programs
Three main reasons:
- Cost savings. Networks typically charge merchants 25–30% on top of the affiliate commission, plus a monthly platform fee. For a merchant with high affiliate volume, those fees add up to real money. Going direct cuts that out.
- Control over the relationship. Direct programs let merchants set custom commission tiers for top affiliates, run exclusive promotions, and form personal relationships with their best partners. Networks impose standardization that big merchants sometimes resent.
- Data ownership. When merchants use a network, the network sees everything — every click, conversion, and affiliate behavior. Some merchants prefer to keep that data in-house, especially if they're using it for product or marketing decisions.
Trade-offs for affiliates
Why in-house programs often pay more
Without the network's 25–30% take, the merchant has more budget to share with affiliates. The savings often show up as:
- Higher commission rates. A SaaS that pays 25% RevShare on its own program might pay only 20% on a network (network takes a slice from the merchant; the merchant cuts the affiliate's share to keep their margin).
- Longer cookie windows. In-house programs frequently use 60-, 90-, or even 365-day cookies (or lifetime RevShare), where the same merchant might offer 30 days through a network.
- Recurring commissions on subscriptions. Many in-house SaaS programs pay lifetime RevShare while their network listings cap at first-year or first-month only.
Why managing many in-house programs is harder
- Separate accounts for each program. 10 in-house programs = 10 logins, 10 dashboards, 10 password managers.
- Separate tax forms. Each US in-house program sends its own 1099 at year-end. Tax prep complexity scales linearly with direct programs.
- Separate payment thresholds and schedules. Some pay weekly, some monthly, some quarterly. Some have $50 minimums, some $100, some none.
- Tracking quality varies. Networks enforce a minimum quality bar; in-house programs are only as good as their software vendor and implementation effort.
- No dispute resolution layer. If a merchant disputes a sale or goes out of business, you have no third party to mediate.
The pattern most working affiliates use
Working affiliates typically settle on the "2–3 networks + 3–5 in-house programs" pattern:
- Networks (2–3) for catalog breadth, easier program discovery, and one consolidated payment for the long tail of smaller programs.
- In-house programs (3–5) for the specific merchants that drive most of the revenue — typically the highest-EPC offers in the niche where the commission lift justifies the management overhead.
