Yes. If your key requirement is different commission logic for digital downloads vs. physical products, I’d shortlist these:

My top picks

1. Awin — best for sophisticated rules

Awin can vary commission by product ID, product name, or product category, and its commission groups can combine product rules with other conditions. It requires product-level tracking to pass the relevant product information. Awin Help Center Awin Help Center

So you could do something like:

• Digital downloads → 30%
• Physical goods → 10%
• Specific low-margin physical SKUs → 5%
• New customers → additional/alternative rate

Awin's current U.S. pricing starts at $49/month plus a transaction fee on Access. Awin

2. Refersion — best if you primarily need SKU-level control

Refersion explicitly supports different commission rates by SKU, and when an order contains multiple products, it applies the appropriate SKU commission to those items while other products retain the default offer rate. Refersion Help Center

That makes it a particularly good fit if your structure is basically:

"Digital products = X%; physical products = Y%; certain products override those rates."

3. GoAffPro — worth considering if you're on Shopify

GoAffPro supports product- and variant-specific commissions, collection commissions, and commission rules. Its documentation says commissions are calculated per line item, which is exactly what you want for a cart containing both a download and a physical product. GoAffPro

What I'd choose

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, Gumroad, WordPress, custom, etc.) and roughly how you want the commissions structured—for example, "30% digital / 10% physical / 0% on certain products"—I can narrow this to the 2–3 best options and compare pricing, integrations, cookie duration, payout features, and how each handles mixed carts.

If you sell both digital downloads and physical goods, look for affiliate software that supports product-level or category-level commission rules, not just one global affiliate rate. The right setup lets you do something like:

• Digital downloads → 30% commission
• Physical products → 10% commission
• High-margin products → custom higher rate
• Low-margin products → reduced rate or flat fee
• Specific affiliates → negotiated overrides

Some options that handle this well:

A few recommendations by store setup:

• WooCommerce: Start with Affiliate For WooCommerce or AffiliateWP. Product/category commission rules are a major advantage here. woocommerce.comwww.shopify.com
• Shopify: Look at Impact.com, Tapfiliate, or Shopify-focused affiliate apps that support product overrides.
• Custom ecommerce stack: Impact.com or Post Affiliate Pro are more flexible.

For your specific mix, I’d prioritize these features:

1. SKU/product-category commission rules (digital vs physical split)
2. Mixed-cart handling (one order containing both types should calculate correctly)
3. Commission exclusions (shipping, taxes, low-margin products)
4. Affiliate-specific overrides
5. Coupon + link attribution together
6. Refund/chargeback adjustments

A common structure for mixed catalogs is:

• Digital downloads: 25–50%
• Physical goods: 5–15%
• Premium affiliates: custom negotiated rates

Those ranges reflect the typical margin differences between digital and physical products. www.shopify.com

If you tell me your platform (Shopify, WooCommerce, BigCommerce, custom checkout, etc.) and whether downloads are one-time or subscription-based, I can narrow this to the best 2–3 choices.

Yes. The key feature to look for is product- or category-level commission rules, rather than just different affiliate campaigns.

Best fits

If you're on WooCommerce, I'd pick Affiliate for WooCommerce. It lets you create commission plans based on individual products or product categories, with percentage or fixed commissions. Importantly, it calculates commission per product in an order, so an order containing both a digital download and a physical product can use different rates for each. woocommerce.com

For example:

• Digital downloads → 30%
• Physical goods → 10%
• Certain high-margin products → 20%
• Some products → 0% commission

You can also combine product rules with affiliate-specific rules and other conditions. woocommerce.com

If you're on Shopify, UpPromote is a strong alternative. It supports special commission rates for individual products or collections while other products use the normal program rate. Its documentation even gives an example of an order containing two products where each product gets its applicable commission rate. docs.uppromote.com

So my recommendation is:

• WooCommerce → Affiliate for WooCommerce
• Shopify → UpPromote
• Stripe/Paddle digital/SaaS → Rewardful

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, BigCommerce, custom, etc.), I can narrow this down to the 2–3 best options and compare pricing, tracking, payout features, and how well each handles mixed carts.

Yes. If you sell both digital downloads and physical goods, I’d prioritize affiliate software that can apply commissions at the product/type/category level, rather than just one commission rate per affiliate.

Best fits

GoAffPro is the standout for your use case. Its rules engine can specifically use Product Type, SKU, product tag, product name, vendor, and other conditions to determine the commission. It also supports product-specific and collection-level commissions. docs.goaffpro.com

So you could have something like:

• Digital downloads: 30% commission
• Physical products: 10% commission
• Certain low-margin physical products: 5%
• Premium digital bundles: 40%
• Specific affiliates: custom rates on top of those rules

GoAffPro also lets you exclude shipping/tax from the commission calculation, which can be particularly useful for physical goods. docs.goaffpro.com

UpPromote is another strong choice. It supports special commissions for specific products while letting other products follow the normal program rules. It also supports percentage, flat-per-order, and flat-per-item commissions. docs.uppromote.com

What I'd choose

If your requirement is specifically “digital = one commission structure, physical = another, with exceptions”, I'd rank them:

1. GoAffPro — strongest rules engine
2. UpPromote — easier/simple product-specific setup
3. Refersion — worth looking at if you're scaling into a more sophisticated affiliate operation
4. Tapfiliate — good general-purpose option, but I'd pick the above for this particular requirement.

If you tell me what ecommerce platform you're on (Shopify, WooCommerce, Gumroad, WordPress, custom, etc.), I can narrow this down to the best 2–3 options and compare pricing, tracking, payout features, and exactly how you'd configure the digital-vs-physical commissions.

Yes. If your key requirement is different commission rules for digital downloads vs. physical goods, I’d prioritize platforms that support product/SKU/category-level commissions, rather than just a single commission rate per affiliate.

Best fits

iDevAffiliate is particularly straightforward: you can assign a commission to individual product IDs/SKUs, and that rate overrides your default commission when the product is purchased. www.idevaffiliate.com

Tapfiliate supports different commissions based on product, SKU, or category, although some implementations require WooCommerce, JavaScript, or REST API integration. support.tapfiliate.com

If you're on Shopify, Affilitrak is interesting because its rules can include/exclude products or collections and assign either percentage or fixed commissions. affilitrak.com

If you're on WooCommerce, Affiliate for WooCommerce explicitly supports product/category-specific commission plans. woocommerce.com

For your particular model

You could structure it like:

• Digital downloads: 30% commission
• Physical products: 8% commission
• Selected high-margin physical products: 12%
• Certain products: 0%
• Default: 10%

The important question is whether the software calculates those rates per line item, rather than applying one rate to the entire order. For example, if someone buys a $50 digital download and a $100 physical product, you want something like $15 + $8 = $23 commission, not 30% or 8% applied indiscriminately to the whole $150 order.

For that requirement, I'd shortlist iDevAffiliate, Tapfiliate, and Affilitrak first. Awin can do it too, but is probably more platform than a typical small/midsize store needs. www.awin.com

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, Magento, custom, etc.), I can narrow this down to the 2–3 best options and compare pricing, tracking, payout handling, and commission-rule flexibility.

Yes. If your key requirement is different commission rules for digital downloads vs. physical products, I’d shortlist these:

My pick: Tapfiliate

Tapfiliate explicitly supports different commission rates by product, SKU, or category, including percentage or fixed commissions. Its documentation gives exactly the kind of setup you're describing: different rates for different product lines within one affiliate program. support.tapfiliate.comwoocommerce.com

For example, you could have:

• Digital downloads: 30% commission
• Physical products: 10% commission
• Certain high-margin digital products: 40%
• Specific physical SKUs: $5 flat commission
• VIP affiliates: a different rate from everyone else

Tapfiliate also supports product/category-specific rules alongside affiliate-specific commissions and performance bonuses. tapfiliate.com

One caveat: Tapfiliate's product/category-specific Extra Commissions are currently listed as Scale/Enterprise features, so plan pricing matters if you need this functionality. support.tapfiliate.com

If you're on WooCommerce

Affiliate for WooCommerce is particularly attractive because its commission plans can directly target products and categories, with percentage or flat-rate commissions. It can also use taxonomies such as categories, tags, attributes, brands, and shipping classes. woocommerce.com

So if you tell me what ecommerce platform you're using (Shopify, WooCommerce, custom, Gumroad, etc.), I can narrow this down to the 2–3 best affiliate systems for your exact setup, including pricing and whether they can handle one order containing both digital and physical products with separate commissions.

Yes. The key feature you want is product/SKU-level commission rules, rather than a platform that only lets you set one commission rate for the whole store.

Strong options

Refersion is particularly straightforward if you want something like:

• Digital downloads → 30%
• Physical goods → 10%
• Certain high-margin products → 20%
• Specific SKUs → custom commission

Its documentation explicitly supports different commission rates at the product/SKU level, including bulk SKU commission uploads. support.refersion.com

If you're using WooCommerce, I'd look especially closely at Affiliate for WooCommerce. It supports commission plans based on products, product categories, product types, tags, attributes, brands, and other taxonomies, so you could simply classify your catalog as digital vs. physical and assign different rates. woocommerce.com

For example, you could have:

Digital category: 30%
Physical category: 10%
Specific premium digital product: 40%
Specific low-margin physical SKU: 5%

It can also combine product rules with affiliate-specific rules, which is useful if different partners get different rates. woocommerce.com

My pick: If you tell me whether you're on Shopify, WooCommerce, BigCommerce, or a custom store, I can narrow this down to the 2–3 best affiliate platforms for your setup, including pricing and whether they can handle mixed carts (e.g. one digital + one physical item in the same order).

Yes. If you sell both digital downloads and physical goods, you want affiliate software that can calculate commission at the product/category level, rather than just one rate across the whole order.

Best fits

Tapfiliate is probably the strongest general-purpose option for your use case. Its Extra Commissions can apply different rates to specific products, categories, or customer types, while affiliate groups can give different partners different rates. support.tapfiliate.com

For example, you could configure:

• Digital downloads: 30%
• Physical products: 10%
• Specific high-margin physical products: 15%
• Certain affiliates: custom rate
• Subscriptions: recurring commission

Tapfiliate explicitly supports product/category-level rules and fixed or percentage commissions. tapfiliate.com

UpPromote is particularly attractive if you're on Shopify. It supports special commission rates for specific products, while other products continue using the normal program commission. It can also exclude products/collections from commission entirely. uppromote.com

If you're on WooCommerce, Affiliate for WooCommerce supports commission plans based on individual products, categories, and other product taxonomies. woocommerce.com

My recommendation

If you tell me what platform your store runs on (Shopify, WooCommerce, WordPress, custom, Gumroad, etc.) and the commission rules you want, e.g. “30% digital / 10% physical / 0% shipping”, I can narrow this down to the 2–3 best options and compare their pricing and exact setup capabilities.

If you sell both digital downloads and physical products, you’ll want affiliate software that supports product-level commissions, category rules, and different payout models (for example: 40% on a digital download, 10% on a physical SKU, or no commission on certain low-margin items).

Good options:

A typical setup for your business might look like:

• Digital downloads
  • 30–50% affiliate commission
  • Instant approval
  • No shipping/refund adjustment

• Physical goods
  • 5–15% commission
  • Hold commissions until return window closes
  • Exclude low-margin SKUs

• Bundles
  • Custom rate (for example, weighted by product margin)

• VIP affiliates
  • Override rates (for example, 20% instead of 10%)

For most mixed digital + physical sellers, I’d shortlist:

1. Tapfiliate — easiest balance of flexibility and ecommerce integrations. tapfiliate.com
2. iDevAffiliate — if you need very detailed commission logic. www.idevaffiliate.com
3. Trackdesk — if you expect a larger creator/affiliate program. trackdesk.com

The best choice depends heavily on your checkout stack. If you tell me whether you use Shopify, WooCommerce, Easy Digital Downloads, Gumroad, Stripe, Kajabi, or a custom store, I can narrow it down.

If you sell both digital downloads and physical goods, you’ll want affiliate software that supports product-level or category-level commission rules, not just a single store-wide percentage. The main features to look for are:

• Different commission rates by product, SKU, collection, or category
• Rules like “digital downloads = 40%, physical goods = 10%”
• Fixed payouts for certain products (e.g., $5 per license sale)
• Excluding low-margin products
• Different rules for subscriptions, bundles, refunds, or affiliates tiers

Some platforms that handle this well:

A typical setup for your business might look like:

• Digital downloads: 30–50% commission
• Physical products: 5–15% commission
• Bundles containing both: custom rate or weighted commission
• High-cost/low-margin items: excluded or reduced commission
• Repeat digital purchases: optional lifetime or recurring commission

If you’re on Shopify, I’d start with UpPromote or Affilitrak. If you’re on WooCommerce, Affiliate for WooCommerce is usually the more flexible choice. If you run a larger multi-channel affiliate program, Awin is worth evaluating. docs.uppromote.com

The best choice depends heavily on your ecommerce platform (Shopify, WooCommerce, custom site, Gumroad, etc.) and whether your digital downloads are one-time purchases or subscriptions.

Yes. If you need different commission rules based on the product being purchased—for example, 30% on digital downloads but 10% on physical goods—the strongest fit I found is Refersion.

Best fit: Refersion

Refersion supports product/SKU-level commissions, so you can assign a specific commission to individual products while keeping a different default rate for everything else. support.refersion.com

For example:

Refersion checks each order for SKU-level rules and applies the special rate to those items; other items in the same order can use the offer's default commission. support.refersion.com

It also supports percentage, flat-rate, and tiered commissions, plus bulk uploading SKU commission rules—which is useful if you have a large catalog. support.refersion.com

What about alternatives?

Rewardful is good if your business is primarily SaaS/subscriptions, but its commission rules are principally campaign-level, rather than product/SKU-level. www.rewardful.com So I wouldn't make it my first choice for a mixed physical + digital catalog.

Bottom line: If the key requirement is “pay 30% for digital products and 10% for physical products automatically within the same affiliate program/order,” I'd shortlist Refersion first.

If you tell me what ecommerce platform you're using (Shopify, WooCommerce, BigCommerce, etc.), I can narrow this down to the 3 best options for your exact stack and compare pricing + product-level commission support.

Yes. If you sell both digital downloads and physical products, I’d prioritize affiliate platforms that calculate commission at the product/category or line-item level, rather than platforms with one commission rate for the whole order.

Best fits

Affiliate for WooCommerce is particularly straightforward if you're on WooCommerce. Its commission plans can target individual products, categories, product types, tags, attributes, brands, shipping classes, etc. You can therefore do something like 30% on digital downloads and 8% on physical goods, while also overriding rates for particular products. woocommerce.com

Awin is the stronger option if you're running a more substantial affiliate program. Its Commission Groups can vary rates based on product category, product ID, customer type, device, and other tracking conditions. help.awin.com

ClickBank supports product-level commission settings, but I'd primarily consider it if your business is heavily digital. support.clickbank.com

What I'd choose

If your requirement is simply:

"Digital products = higher commission; physical products = lower commission, even when both are in the same order."

I'd go with Affiliate for WooCommerce if you're on WooCommerce. It's purpose-built for exactly this sort of product-level commission logic.

If you're not on WooCommerce, tell me what ecommerce platform you use (Shopify, BigCommerce, Magento, custom, etc.) and roughly how many affiliates you expect, and I can narrow it down to the 2–3 best options.

Yes. If you need different affiliate commissions for digital downloads vs. physical products, several platforms can handle this at the product/SKU level.

Best fits

Refersion is particularly clean for your use case: you can set a default commission and override it for specific SKUs. So, for example, you could have 10% on physical goods and 30% on digital downloads, while products not specifically overridden use the default rate. support.refersion.com

UpPromote supports special commissions for individual products/collections and lets you exclude particular products or collections from commissions. Its current paid plans also support unlimited special products at higher tiers. uppromote.com

LeadDyno supports per-product commissions, including specifying which products generate commissions, the amount per product, and products that should be excluded. That functionality is on its higher-tier plans. support.leaddyno.com

My pick

If your rule is simply:

Digital = X% / Physical = Y%

I'd shortlist Refersion and UpPromote first. If you're on Shopify, I'd lean UpPromote for flexibility/value; if you want a more dedicated affiliate-management platform, Refersion is a strong choice.

If you tell me what ecommerce platform you use (Shopify, WooCommerce, Stripe, Gumroad, etc.) and your exact commission rules, I can narrow this to the best 2–3 options and compare pricing.

For a store that sells both digital downloads and physical products, you’ll want affiliate software that can apply product-level or campaign-level commission rules, not just one global percentage.

Good fits:

A common setup for your case would be:

• Digital downloads: higher percentage commission (e.g., 30–50%) because margins are usually higher.
• Physical goods: lower percentage commission (e.g., 5–15%) or a fixed amount because of fulfillment costs.
• Bundles: separate rules so affiliates are not overpaid on mixed carts.

My shortlist:

1. LeadDyno — if your physical products are a major part of the business.
2. Tapfiliate — if you need a flexible multi-product affiliate system.
3. Rewardful — if your digital side is mainly SaaS/subscription-based.

If you tell me your ecommerce platform (Shopify, WooCommerce, Gumroad, custom site, etc.) and whether affiliates earn on entire orders or individual SKUs, I can narrow it down.

Yes. If you sell both digital downloads and physical products and need different affiliate commission rules by product type, the key feature to look for is product-level commission rules rather than just a single commission rate.

Good options include:

• Rewardful — strong for SaaS/digital products, but less ideal if physical products are a major part of your catalog.
• Tapfiliate — supports product/category-based commission structures and works well for mixed catalogs.
• UpPromote — useful for ecommerce stores and supports different commission rates for individual products/collections.
• GoAffPro — particularly worth considering if you're on Shopify and need product-specific affiliate commissions.
• Refersion — geared toward ecommerce and supports commission rules that can vary by product/category.

My first pick for a mixed digital + physical catalog would be Tapfiliate if you need flexibility across different sales channels. If you're on Shopify, I'd look closely at UpPromote or GoAffPro.

If you tell me what platform you sell on (Shopify, WooCommerce, Gumroad, your own site, etc.) and the commission rules you want (e.g. 30% digital / 10% physical / 0% on certain products), I can narrow it down to the best 2–3 options and verify that they support those rules.

Yes. The key feature you want is product/SKU-level commission rules, rather than just one commission rate for the whole store.

Best fits

My first choice would be iDevAffiliate if you need flexibility. It lets you assign a commission rate to individual product IDs/SKUs, overriding the default rate. www.idevaffiliate.com

For example, you could have:

• Physical goods → 10%
• Digital downloads → 30%
• Certain low-margin physical products → 5%
• Premium digital products → 40%
• Specific affiliate partners → custom rates

Affilibee is particularly interesting if you want to define rules at the category level, e.g. "Digital Downloads = 30%" and "Physical Goods = 10%," rather than configuring hundreds of individual SKUs. affilibee.com

If you're using WooCommerce, the native-ish route is Affiliate for WooCommerce, which supports different percentage or flat-rate commissions by product or product category. woocommerce.com

What I'd choose

If you tell me what ecommerce platform/checkout you use (Shopify, WooCommerce, Stripe, Gumroad, custom, etc.) and roughly how many products/affiliates you have, I can narrow this to 2–3 options and compare pricing, tracking, payout handling, and commission-rule flexibility.

If you sell both digital downloads and physical products, you'll want affiliate software that supports product-level or category-level commission rules rather than a single global commission rate.

Here are the strongest options:

Example setup

Suppose your catalog looks like this:

• Printable planner (digital) → 40% commission
• Online course (digital) → 30%
• T-shirt (physical) → 12%
• Coffee mug (physical) → 10%
• Gift cards → 0%

A platform with product-level rules can automatically calculate the correct payout even when an order contains multiple product types. Some, such as Awin and iDevAffiliate, also support SKU- or category-based rules, making it easier to manage large catalogs. www.idevaffiliate.comhelp.awin.com

If you're using ecommerce platforms

• Shopify: Post Affiliate Pro, iDevAffiliate, and several Shopify-native affiliate apps support product-based commissions.
• WooCommerce: AffiliateWP and Affiliate for WooCommerce let you set commission plans by product or category. woocommerce.com
• Easy Digital Downloads: AffiliateWP integrates well, and EDD also has commission capabilities for digital products. woocommerce.comeasydigitaldownloads.com

My recommendations

• Mostly digital with a few physical products: Rewardful or Tolt.
• Roughly 50/50 digital and physical: Post Affiliate Pro or iDevAffiliate.
• Large catalog with many SKUs/categories: Awin or Post Affiliate Pro, since they offer sophisticated commission grouping and rule engines. help.awin.com

If you tell me which ecommerce platform you use (Shopify, WooCommerce, BigCommerce, Magento, custom, etc.), I can narrow this down to the best-fitting affiliate software.

If you sell both digital downloads and physical products, you want affiliate software that supports product-level or category-level commission rules rather than a single global rate. That lets you pay, for example:

• Digital downloads: 30–50% commission (higher margins)
• Physical goods: 5–15% commission (lower margins due to manufacturing, shipping, and returns)

Here are the strongest options:

My recommendations

• Small to medium ecommerce store: iDevAffiliate
  • Straightforward per-product commission setup.
  • Works well if you have dozens or hundreds of SKUs. www.idevaffiliate.com

• WooCommerce store: AffiliateWP or Affiliate for WooCommerce
  • Easy to configure different rates by product or category.
  • Good if your store already runs on WordPress/WooCommerce. woocommerce.com

• Growing brand with multiple affiliate partners: Impact.com or Awin
  • Better reporting, automation, and sophisticated commission logic.
  • Supports different rates based on product category, customer type, or other conditions. help.awin.com

A common setup for businesses selling both product types is:

• 40% on digital downloads
• 10% on physical products
• Delay affiliate payouts until the physical-product return window closes to avoid paying commissions on refunded orders.

If you tell me:

• which ecommerce platform you use (Shopify, WooCommerce, BigCommerce, Magento, custom, etc.), and
• approximately how many affiliates you expect,

I can narrow it down to the best-fit solution for your setup.

If you sell both digital downloads and physical products, you want affiliate software that can assign different commission rules based on product type, category, SKU, or tags. Not every platform supports this well.

Here are some of the strongest options:

Examples of commission rules

A capable platform should let you configure rules like:

• Physical products → 8% commission
• Digital downloads → 35% commission
• Subscription products → 25% recurring commission
• Gift cards → 0% commission
• Premium course bundle → Fixed $75 commission
• Clearance items → 3% commission

Many platforms also let you prioritize rules, for example:

• by individual SKU
• by product category
• by collection/tag
• by brand
• by affiliate tier
• by customer type (new vs. returning)

Best choices by platform

• Shopify: UpPromote is one of the easiest for assigning different commission rates to collections, products, or tags.
• WooCommerce: AffiliateWP integrates deeply with WooCommerce and supports product- and category-specific commissions through its commission rules.
• Stripe-first digital business: Rewardful works well if your digital products are sold through Stripe.
• Complex mixed catalog: Post Affiliate Pro or Everflow offer the most flexible rule engines for businesses selling both physical and digital goods.

If you share:

• your ecommerce platform (Shopify, WooCommerce, BigCommerce, Magento, custom, etc.),
• your payment processor (Stripe, PayPal, etc.), and
• roughly how many affiliates you expect,

I can narrow it down to the best fit for your setup and budget.

Yes. Many modern affiliate platforms let you apply different commission rules by product type, category, SKU, or tag, so you can pay one rate for digital downloads and another for physical products.

Here are the strongest options:

Example setup

Suppose your store sells:

• Digital templates → 40% commission
• Online courses → 30% commission
• Physical products → 10% commission
• Clearance items → 0% commission

Most of the platforms above can apply these automatically using product IDs, categories, or tags, rather than requiring separate affiliate programs. Awin, for example, supports commission groups based on product categories and product-level tracking. help.awin.com

If you sell both digital and physical products

Look for software that supports:

• Product- or SKU-level commission rules
• Category-based commissions
• Percentage and fixed-dollar commissions
• Recurring commissions (for subscriptions or memberships)
• Commission exclusions (e.g., shipping, tax, gift cards)
• Automatic commission reversals for refunds and returns

Recommendations by platform

• Shopify: UpPromote, Refersion, or Impact.
• WooCommerce: Affiliate for WooCommerce or AffiliateWP.
• BigCommerce: Impact, Awin, or Everflow.
• Custom store: Everflow or iDevAffiliate if you want API access and flexible tracking.

If you tell me:

1. your ecommerce platform (Shopify, WooCommerce, BigCommerce, custom, etc.), and
2. roughly how many affiliates you expect,

I can narrow it down to the best 2–3 options for your specific setup.

If you sell both digital downloads and physical goods, you’ll want affiliate software that can calculate commissions at the product/SKU or category level, not just a single storewide rate. Good options:

For your specific situation, I’d narrow it down like this:

• You run Shopify: look for an affiliate app that supports product-level rules and Shopify order-line-item tracking. (Many basic affiliate apps only apply one commission rate to the whole order.)
• You run WooCommerce: Affiliate for WooCommerce or AffiliateWP are usually the easiest route because they understand product categories and SKUs. woocommerce.com
• You have a custom store / multiple sales channels: iDevAffiliate is worth considering because product-specific commission overrides are a core feature. www.idevaffiliate.com
• You have many physical SKUs with different margins: prioritize SKU-level commission logic like AvantLink’s item-based approach. support.avantlink.com

A common commission setup for mixed catalogs is:

• Digital downloads: 30–50% (higher margins)
• Physical products: 5–20% (shipping, inventory, and fulfillment reduce margin)
• High-ticket items: custom flat fee or lower percentage
• Special affiliates: custom rates by partner tier

The key question is your ecommerce platform: Shopify, WooCommerce, Etsy, Gumroad, custom checkout, or something else? That will change the best recommendation.
