Affiliate Marketing Management: How to Track and Pay Affiliates

What affiliate marketing management involves

Affiliate marketing management is the work of running a program in which independent partners, such as bloggers, creators, review sites and newsletters, promote your products and earn a commission on the sales they refer. Managing it well means five things: setting clear commission terms, recruiting the right affiliates, tracking every referred sale accurately, paying affiliates correctly and on time, and making sure their promotions follow advertising law and search engine guidelines. Get those right and affiliates become a sales channel you only pay for when it works.

This guide replaces our older post on following and paying affiliates with a step-by-step process for ecommerce brands, including tools for Shopify stores, tax paperwork for US payouts and the FTC’s disclosure rules. Rules and thresholds come from the FTC, IRS and Google, checked as of October 2026, with sources listed at the end. PROSeCommerce, part of PROS Global in San Diego, helps ecommerce brands plan and run marketing channels, including affiliate and creator programs, so the guidance focuses on the merchant’s side of the program.

How an affiliate program works

Every affiliate program follows the same basic loop:

1. An affiliate joins your program and receives a unique tracking link or discount code.
2. The affiliate promotes your products to their audience with that link or code.
3. A shopper clicks or uses the code and buys from your store.
4. Your tracking software credits the sale to the affiliate.
5. After any return window passes, you approve the commission and pay the affiliate.

You can run the program yourself with affiliate software or an app, or join an affiliate network that brings its own pool of publishers, tracking and payment handling in exchange for fees. In-house programs give you more control and direct relationships. Networks give you faster reach but less control over who promotes you.

Step 1: Set goals and commission terms

Start with the numbers. Your commission has to leave room for product costs, shipping, payment fees, returns and profit, so work out your contribution margin per order before you pick a rate.

Choose a commission model

• Percentage of sale: the most common model for online stores, easy for affiliates to understand
• Flat fee per order: simpler to budget when order values vary widely
• Tiered rates: higher rates for affiliates who pass sales targets, which rewards your best partners
• New-customer bonus: a higher rate for first orders than for repeat customers, if your tracking can tell them apart

Write clear terms

Put the rules in a written affiliate agreement that every partner accepts. Cover at least:

• Commission rate and what counts as a qualifying sale
• Cookie or attribution window and how you handle multiple affiliates on one order
• Return and chargeback policy, and how long you wait before approving commissions
• Payout schedule, minimum payout and payment method
• Approved and banned promotion methods, such as bidding on your brand name in search ads, coupon sites or email
• Required disclosures and claims affiliates may and may not make
• Your right to reverse fraudulent commissions or remove affiliates

Have a qualified attorney review the agreement, especially if you work with affiliates outside the US.

Step 2: Recruit the right affiliates

Quality matters more than numbers. A small group of affiliates whose audience matches your customers will usually outsell a long list of inactive sign-ups.

Good places to find partners:

• Your own customers: fans who already recommend you are often your best affiliates
• Content creators in your niche: bloggers, YouTubers and social creators who review products like yours
• Newsletters and communities: publishers with engaged, specific audiences
• Complementary brands: stores selling related products to the same customers

Shopify stores can use Shopify Collabs, which Shopify describes in its marketing help pages as a way to connect with creators and influencers for affiliate and creator-led marketing. Many third-party affiliate apps also integrate with Shopify. Our guide to Shopify social media integration covers how to connect the social channels where many creators promote products.

Review each applicant before you approve them. Look at their content, audience, traffic sources and past partnerships, and decline sites that look like copied product feeds, spammy coupon pages or anything you would not want your brand next to.

Step 3: Onboard and support affiliates

Affiliates sell more when you make it easy for them. Give every new partner a short welcome kit with:

• Their tracking link, any personal discount code and how to create deep links to specific products
• Brand guidelines, approved product images and short product descriptions
• A list of approved product claims and the claims they must not make
• Disclosure instructions, with examples of good wording
• Upcoming launches, promotions and seasonal dates

Then keep in touch. A monthly update with new products, top-selling items and current offers helps keep affiliates active. Our ecommerce marketing strategies guide has more ideas for promotions that affiliates can share.

Step 4: Track affiliate sales accurately

Tracking is the part of affiliate management that causes the most disputes, so set it up carefully and test it before launch.

Tracking methods

• Referral links with cookies: a click on an affiliate link stores an identifier, and a purchase within the attribution window is credited to that affiliate
• Discount codes: each affiliate gets a unique code, which also tracks sales from podcasts, video and offline mentions where links aren’t clickable
• Combined tracking: using both links and codes catches more of the sales affiliates really drive

Test before you launch

Place real test orders through a test affiliate link and code. Confirm that the order is credited to the right partner, that the commission is calculated correctly, and that discounts, shipping and taxes are handled the way your terms say. Repeat the test after any checkout, theme or app change.

Watch for fraud and overlap

Review new affiliate sales regularly. Warning signs include sudden spikes from new partners, many orders that are later refunded, orders placed by the affiliate themselves, and affiliates bidding on your brand name against your terms. Decide in advance how you will credit an order that touched more than one affiliate or one of your own paid ads, and write it into your terms.

Step 5: Pay affiliates correctly and on time

Late or confusing payments are one of the fastest ways to lose good affiliates.

Set a predictable schedule

Most programs approve commissions only after the return window closes, then pay monthly. State the schedule, the minimum payout and the payment method in your terms, and stick to them. Send each affiliate a statement showing orders, returns, approved commissions and the amount paid.

Collect tax information before the first payment

For US-based affiliates who are not your employees, collect a Form W-9 before you pay them. The IRS’s Instructions for Forms 1099-MISC and 1099-NEC say to report nonemployee compensation, including fees and commissions, in box 1a of Form 1099-NEC when payments total $2,000 or more. The current instructions apply that $2,000 threshold to payments made after 2025, and the IRS notes it may be adjusted for inflation in later years. Payments through card processors or some payment apps may be reported differently, and foreign affiliates need different forms, so confirm the details with your accountant.

Keep good records

Keep the affiliate agreement, tax forms, commission reports and payment records together for each partner. Good records make year-end reporting easier and settle disputes quickly.

Step 6: Keep the program compliant

Affiliate promotions are advertising, and as the merchant you share responsibility for what your affiliates say about your products. This is general information, not legal advice.

Make sure affiliates disclose clearly

The FTC’s guidance Endorsement Guides: What People Are Asking says affiliates should disclose their relationship with the retailer clearly and conspicuously, as close as possible to the recommendation. It gives the example “I get commissions for purchases made through links in this post.” The same guidance says:

• “Affiliate link” on its own may not be understood, and “commissionable link” is probably not a clear disclosure
• “Paid link” right next to an affiliate link should be adequate
• A single disclosure on a home page is not enough
• In videos, the affiliate relationship should be disclosed in the video itself and in the description near the links
• A personalized discount code may not tell people the creator is paid, so add a clearer disclosure when in doubt

Train and monitor your affiliates

The FTC says advertisers need reasonable programs to train and monitor members of their network. It lists four elements: explain what affiliates can and can’t say about your products, instruct them on how to disclose their connection to you, periodically search for what they are saying, and take appropriate action if you find problems. Pre-approving paid posts makes this easier.

Follow search engine guidelines

Google asks site owners to mark paid links with the rel=”sponsored” attribute and still accepts rel=”nofollow”, according to its guide to qualifying outbound links. Its spam policies describe thin affiliation, meaning pages that copy merchant product descriptions without adding original value, and say good affiliate pages add value through original reviews, testing, comparisons and price information. Encourage affiliates to create original content rather than copying your product pages.

Step 7: Measure and improve the program

Review the program monthly with a small set of numbers:

• Revenue and orders by affiliate: who is really selling
• Conversion rate of affiliate traffic: whether referred visitors buy
• Average order value and refund rate: the quality of referred orders
• Commission cost as a share of affiliate revenue: whether the channel is profitable
• Active affiliates: how many partners made at least one sale

Reward top performers with higher tiers, early product access or exclusive codes. Reach out to inactive partners once with fresh material, then remove those who stay inactive. If affiliate traffic converts poorly, look at the landing pages; our guide to Shopify conversion rate optimization explains where to start.
