impact.com is the biggest name in this directory and the only one where a one-star review involves a collections agency.
I don't mean that as a cheap shot. It's the clearest way to say what impact.com is: a contract, not a subscription. You sign for twelve months, the fees debit from a funding account you prefund, and when you want out, the process is a support ticket and a settlement, not a cancel button. Everything good and bad about it follows from that.
Disclosure: the link on this page is my affiliate link. impact.com pays me if you become a customer through it. That hasn't changed a word of what follows, and you can go to impact.com directly if you'd rather.
I haven't run a program on impact.com. What follows is their published plans, their help centre, their Shopify listing and the reviews, including a Better Business Bureau file that's more useful than most of the five-star ones.
Who it's for
Brands with a partnerships person. Not a founder who also does partnerships; someone whose job it is. impact.com is built for companies running affiliates, influencers, publishers, B2B referrers and brand ambassadors as one function, with contracts, compliance and reporting that a finance team will sign off on.
If you're a DTC brand past seven figures with a Shopify store and an agency or an in-house manager, or a SaaS company that's outgrown PartnerStack's marketplace, this is the room you end up in. It has the biggest publisher base in the category, and the publishers who matter (coupon sites, cashback apps, big content properties) are already there.
Who should skip it
Anyone who'd describe their affiliate program as "a few people with links." You'll pay enterprise prices for a tool whose value is managing hundreds of partners you don't have.
Anyone who can't commit to twelve months. More on that below, because it's the whole review.
Anyone who wants to try it and leave if it doesn't work. The Starter plan lets you cancel self-serve during the trial. After that, you're in the ticket queue.
Pricing, decoded
impact.com is one of only two networks in this directory that publishes prices. Credit where due.
- Starter: from $30/month plus 2.5% of transactions. Requires an integration with Shopify, WooCommerce, BigCommerce, Adobe Commerce, Squarespace, Ecwid or similar. Self-serve.
- Essentials: $500/month. Partner payouts up to $2,500 a month.
- Pro: $2,500/month. Payouts up to $14,300 a month.
- Enterprise: $10,000/month. Payouts up to $82,500 a month.
Above each cap there's an "Incremental Growth Fee," and the percentage isn't published. There's also a one-time setup fee "based on technical resources," also not published. Add-ons for creator management, advocate programs, optimisation and brand safety sit on top.
The caps are on partner payouts, which is more honest than Rewardful's referred-revenue cap, because it tracks what you're actually paying out. But look at the jumps. Essentials to Pro is five times the price for roughly six times the payout room. If your program pays $3,000 a month in commissions, you're on Pro at $2,500 a month, so the tool costs nearly as much as the affiliates.
Worked: at $10,000 a month in affiliate sales with a 20% commission, you're paying $2,000 in commissions. On Starter that's $30 plus $250, so $280. On Essentials it's $500 flat. At $50,000 a month, commissions are $10,000, which puts you on Pro at $2,500. Compare that to Reditus at $399, Tolt at $199, or Awin at $49 plus 2.5%.
So the Starter plan is a real bargain if you qualify for it. Everything above it is priced for companies where $2,500 a month is a line item nobody questions.
The contract, which is the whole review
Here's what the reviews agree on, across Shopify, Capterra and the BBB.
Twelve-month term. Cancelling early means you owe the balance. A Canadian brand on the Shopify listing in May 2026 asked for early termination and was told the full remaining fees were due. A BBB complaint from July 2026 describes cancelling in writing in August 2025, continuing to be billed, and roughly $13,000 being sent to collections. Another from May 2025: paid $500, asked to end the twelve-month agreement, refused.
Then the mechanics. Fees are auto-debited from your funding account before partner payouts, so if the account's low, impact.com gets paid and your affiliates wait. Uninstalling the Shopify app does not cancel the agreement. On Starter, after the trial, cancelling means a support ticket, expiring every partner contract, and settling invoices; "billing continues until you request closure," in their words.
None of this is hidden. It's in the agreement. But the gap between "install an app from the Shopify store" and "sign a twelve-month contract with collections consequences" is wide, and the reviews are from people who fell into it.
What it does well
Scale. Hundreds of partners, multiple partner types, contracts per partner with their own terms, compliance monitoring, fraud tooling, and reporting that a CFO will accept. If PartnerStack is a marketplace with a tool attached, impact.com is an operating system for partnerships.
The export is the best in the networks category. You can download your full partner list and contact list, with names, URLs, emails, phone numbers and addresses, as CSV or Excel, plus an API. Awin won't give you publisher emails. impact.com will. That matters enormously if you ever leave, and it's the reason the lock-in score below isn't a five.
Payouts are managed. Fund the account by ACH, impact.com pays partners, W-9s and W-8s are collected. Auto-funding is USD only.
Lock-in: 4 out of 5
What gets you out: the export, which includes partner contact details. The API. Your Shopify or Woo integration is a standard one, so swapping tools on the store side is routine.
What keeps you in: the twelve-month contract, which keeps you in whether you're using it or not. The funding account, where your money sits before it goes to partners. Partner contracts that have to be individually expired before the account closes. And the publishers themselves: the big coupon and cashback sites work through networks, and if you leave impact.com for a standalone tool, those relationships don't come with you, because they were never really yours.
Four, not five, because of the export. A five would be a tool that keeps your data and your contract. impact.com only keeps the contract.
Gotchas
- Twelve-month term with no termination for convenience. Read the agreement before the trial ends.
- Uninstalling the Shopify app doesn't cancel anything. Several reviewers found out the expensive way.
- Fees debit before partner payouts. Keep the funding account topped up or your affiliates wait while impact.com doesn't.
- Setup fee and overage percentage aren't published. Ask for both in writing before signing.
- Starter requires a supported cart. No Stripe-only SaaS on the $30 plan; that's Essentials at $500.
- Fraudulent orders paid out. A 2024 Shopify review describes about $6,000 in disputed payouts on fraudulent orders. Another describes fraud on top of the twelve-month lock-in. Turn on the fraud tooling before you turn on the program.
- Onboarding complaints. BBB, February 2026: no onboarding, tickets open 100 days, invoices still arriving. Capterra, June 2026: an unexpected $1,000 at onboarding.
- Trustpilot is 1.2 out of 5, but almost entirely from publishers, not brands. Useful for knowing how your affiliates will feel about the platform, less so for your own decision.
Integrations
Shopify, WooCommerce, BigCommerce, Adobe Commerce, Squarespace, Ecwid and other carts on Starter. Universal tag and API for everything else. HubSpot and Salesforce on the higher tiers. Stripe-billed SaaS goes through the API, not a one-click connection.
If you're leaving
Start by reading your agreement for the term end date and notice period, and put both in your calendar now. Download the partner list and contact list while you still have access; that's the asset. Expire partner contracts, settle every invoice, and get written confirmation that the account is closed. Then, and only then, uninstall the app. If you cancel in writing and keep getting billed, keep every email, because the BBB file suggests you'll need them.
Verdict
If you have a partnerships team, hundreds of partners across several types, and the finance function to sign a twelve-month agreement with open eyes, impact.com is the most capable platform in this directory, and the Starter plan at $30 plus 2.5% is a fair way in for a Shopify brand that qualifies.
If you don't have those things, the contract is the product, and everything the reviews complain about is a consequence of signing it without a partnerships budget. Reditus, Tolt, Awin or a Shopify app will get you most of the way for a tenth of the money and no collections agency.
