Checkout and funnel software reviews

The NMI fee schedule your ISO should show you

NMI has no public merchant rate card. Ask the ISO for the portal schedule, then see how Shopify and WooCommerce connect.

paid-traffic funnels where the landing page, the checkout and the sale stay on one customer record

ElasticFunnels

ElasticFunnels is the pick if you run paid ads and need to test whole checkouts under one URL while sending sales across several merchant accounts.

high-volume direct-response brands that have outgrown a single processor

Checkout Champ

Checkout Champ is the pick if you run high-volume direct-response offers and have outgrown a single processor, as long as you can accept a demo-gated setup and a bill that scales with your sales.

From

$300/mo

sellers who want a hosted checkout on SamPay, Stripe or PayPal, with bumps and upsells on the Pro plan

SamCart

Sellers leave SamCart when bumps and upsells sit on the Pro plan, or when the monthly price is the reason to switch. Keep SamCart if you want the checkout on SamPay, Stripe, or PayPal, and you want it live quickly.

course creators, coaches and info-product sellers who want funnels, checkout, email and a member area in one hosted account

ClickFunnels

ClickFunnels is the pick if you are starting out and want proven templates and a familiar platform that bundles pages, checkout and email.

From

$97/mo

bumps and upsells on a monthly plan or a lifetime license

ThriveCart

Use it when checkout is the priority: order bumps, upsells and checkout tests, on a monthly plan or a lifetime license, while the course stays where students already watch.

agencies and paid-traffic sellers who want CRM, funnels and SMS together

GoHighLevel

GoHighLevel is the pick if you run an agency or paid ads and want CRM, funnels and SMS under one login. The order form allows one card processor.

From

$97/mo

subscription sellers and affiliate-driven launches that want checkout, recurring billing and a referral program in one account

PayKickstart

PayKickstart is the pick if you sell subscriptions or run affiliate launches and want checkout, recurring billing, dunning and a full affiliate program under one login, and you can invest the setup time it asks for. It is not a page builder, so it is the checkout at the end of a funnel you build elsewhere.

From

$79/mo

coaches and course creators who want one login instead of a stack of tools

Kartra

Kartra is the pick if you are a coach or creator who wants pages, email, checkout, courses and memberships on one login, and you can live with a slow builder. It is not built for paid-traffic direct response, where same-URL split testing and payment routing matter more.

From

$59/mo

beginners and solo creators who want a truly free way to run funnels, email and courses in one place

Systeme.io

Systeme.io is the pick if you are starting lean and want a genuinely free way to run funnels, email and courses on one login. It is not built for paid-traffic direct response, where same-URL split testing and payment routing matter more.

software, SaaS and digital-product sellers who want tax and compliance handled

Paddle

Choose Paddle if you sell software, SaaS or digital products and you want Paddle to handle sales tax, VAT and compliance on those sales. If you sell physical products, supplements or a business opportunity, Paddle's own rules rule you out before price ever enters the decision.

creators selling a first digital product without a monthly fee

Gumroad

Gumroad is the pick if you want the simplest possible way to start selling a digital product: no monthly fee, a checkout live in minutes, and sales tax handled for you as merchant of record. It is real, it has run since 2011, and it pays creators every week. The catch is the price of that simplicity. A flat 10% plus 50 cents per direct sale, on top of card processing, gets expensive as you grow, its rules bar physical goods and most high-risk offers, and it is not a checkout you can split-test or route across processors. For a first product it is a fast start. A paid-traffic business usually outgrows it.

established coaches and creators running their whole business from one dashboard

Kajabi

Kajabi is a real, established platform that is genuinely good for coaches and course creators who want one login for courses, community, email and checkout. For a paid-traffic seller it is the wrong tool and an expensive one: the checkout runs a single processor with no same-URL split testing or payment routing, and plans start at $179 a month.

From

$179/mo

software, SaaS and digital-product sellers who want tax handled for them

Lemon Squeezy

Lemon Squeezy is the pick if you sell software, SaaS or a digital product and want sales tax handled for you as merchant of record, with a checkout you can stand up in an afternoon. It is real, it has run since 2021, and Stripe now owns it, so the payments layer underneath is about as solid as it gets. Since the 2024 acquisition, support and product updates have slowed, and account reviews and payout holds are the loudest long-term complaint. The product handles tax and billing for digital sales. Same-URL split testing and routing across processors belong to a different kind of checkout. For a paid-traffic seller it is the wrong category. For a digital-product seller who wants the tax work off their desk, it is one of the easier ways in.

WooCommerce store owners who want a better checkout with order bumps, upsells and A/B testing without leaving WordPress

CartFlows

CartFlows is the pick if you run a WooCommerce store and want a better checkout with order bumps, one-click upsells and A/B testing without leaving WordPress. It is not built for media buyers who need same-URL split testing or payment routing across several merchant accounts.

direct-response digital and supplement offers that want a built-in affiliate army

ClickBank

ClickBank is the pick if you sell a direct-response digital or supplement offer and want an army of affiliates promoting it with the merchant and tax work handled for you. It is real, it has paid on time since 1998, and it takes nothing until you make a sale. The catch is what it is not. ClickBank is an affiliate marketplace and merchant of record, not a funnel builder: you host your own sales page, you cannot split-test the checkout under one URL or route payments across your own merchant accounts, and its 7.5% plus $1 cut, refund clawbacks and dormant-account fees are real costs. For running affiliates it is proven. For building and tuning your own paid-traffic funnel, it is the wrong tool.

From

$49.95/mo

European and global direct-response offers that want a reseller plus a built-in affiliate network

Digistore24

Digistore24 is the pick if you sell a digital or supplement offer to a US, European or global audience and want a reseller that takes the payment, files the tax, handles refunds and brings its own affiliates. It charges nothing until you sell, then keeps a cut of each sale that depends on which of its reseller companies sells for you. The trade-off is control: it is the only processor on every order and the buyer is legally its customer, so it suits affiliate-driven launches better than a checkout you want to own and route yourself.

SaaS and digital-product sellers who want worldwide tax handled

FastSpring

FastSpring is the pick if you sell SaaS, software or another digital product to a global audience and want payments, subscriptions and worldwide sales tax handled for you as merchant of record. It is real and it has run since 2005. But if you sell physical products, supplements or a business opportunity, or you run paid traffic and need to split-test checkouts and route payments across processors, it is the wrong category, and in most cases it will not take your account.

WooCommerce stores that want an optimized checkout with order bumps and upsells plus a built-in CRM and email and SMS automation, without leaving WordPress

FunnelKit

FunnelKit is the pick if you run a WooCommerce store and want an optimized checkout with order bumps and one-click upsells, plus a built-in CRM and email and SMS automation, all inside WordPress. It is the wrong stack for media buyers who need a test on one URL or payment routing across several merchant accounts.

high-volume direct-response and subscription brands that bring their own pages

Konnektive

Konnektive is a CRM and payment platform for direct-response and subscription offers, running since 2010. It is the pick if you sell at volume, often in nutra or another high-risk vertical, and need each sale routed across many merchant accounts on one CRM. The catch is a price you only hear on a sales call, a dense interface, and same-URL split testing that the public site does not describe.

high-volume subscription and direct-response brands that route payments across many merchant accounts

Sticky.io

Sticky.io is the pick if you run high-volume subscription or direct-response offers and need to route payments across many merchant accounts and win back failed rebills on one platform. It is real: it is the rebranded LimeLight CRM, it has run since 2009, and it processes billions of dollars a year. The catch is there is no free trial, the base license starts at $499 a month plus a percentage of every sale, the interface is dated, and there is no same-URL split testing.

budget-minded solopreneurs who want a whole marketing stack under one login and one bill

Builderall

Builderall is real: it has run since 2017 and says more than 2 million people use it, and for the price you get a genuine stack of 25-plus tools under one login. You will regret it if you expected each tool to match a specialist, or if you run paid traffic that cannot survive an outage, because reviewers report weekly downtime, a laggy builder, and a single-processor checkout with no same-URL split testing. It suits a budget-minded solopreneur who wants everything in one cheap place. A media buyer scaling cold traffic will run into those limits quickly.

experienced health and wellness affiliates and vendors who want a curated, high-payout marketplace

BuyGoods

BuyGoods is the pick if you are an experienced health or wellness marketer who wants a curated, high-paying affiliate marketplace that handles the checkout, tax and payouts for you. It is real, it says it has paid out more than $3 billion since around 2016, and it pays affiliates weekly. The catch is what it is and who it is for. BuyGoods is a nutra-focused marketplace and merchant of record, not a funnel builder: you cannot join without a referral or a proven track record, you cannot split-test your own checkout under one URL or route payments across your own merchant accounts, and because it is the seller of record its buyer-side complaint volume attaches to your offer. For running or promoting supplement offers it is proven. For building and owning your own paid-traffic funnel, it is the wrong tool.

solo marketers and agencies who run paid traffic and want the fastest-loading landing pages and funnels, with checkout, upsells and A/B testing built in

Convertri

Convertri is the pick if page speed is your bottleneck: it builds landing pages and funnels that load fast, with a built-in checkout, order bumps and upsells. It is not built for high-volume paid traffic that needs same-URL split testing or payment routing across merchant accounts, and its support and reliability draw mixed reports.

From

digital product and software launches built around JV partners, leaderboards, and fast listing

JVZoo

JVZoo is the pick if you sell a digital or info-marketing product and want a built-in army of affiliates promoting it, with commissions paid to them automatically the moment a sale closes. It is real: it has run since 2011, has more than 800,000 affiliates, and it takes nothing until you make a sale. The catch is what it is and what it is not. JVZoo is an affiliate marketplace and checkout for the internet-marketing niche, with only shallow funnel tools. You write your own sales page, you cannot split-test the checkout under one URL or route payments across your own merchant accounts, and the marketplace is unvetted, so strong offers sit beside over-hyped, low-quality ones. For launching a digital offer to affiliates it works. For building and tuning your own paid-traffic funnel, it is the wrong tool.

experienced direct-response affiliates who want a curated CPA network with fast, reliable payouts

MaxWeb

MaxWeb is the pick if you drive paid traffic to health and wellness offers and want a curated CPA network that pays weekly and gives you a real account manager. It is real and well regarded: it ranks among the top CPA networks in its vertical, and long-term affiliates say the payments never miss. The catch is what it is and who it is for. MaxWeb is a CPA affiliate network built around top-converting video sales letters, and the advertiser owns the checkout and the funnel. You cannot build or split-test your own pages here or route payments across your own merchant accounts, the approval gate is strict, and the first payout is held 30 days and needs five sales per offer. For an experienced direct-response affiliate it delivers. For a seller who wants to own and route their own checkout, it is a different category of tool.

It is not built for paid-traffic direct response, where same-URL split testing and payment routing matter more.

mobile-first lead generation, appointment and recruiting funnels run on paid social

Perspective

Perspective is the real thing: a mobile-first funnel builder that agencies and lead-gen businesses genuinely like, and it is well made. You will regret it only if you expected a sales checkout you can split-test and route across merchant accounts, because it is built to capture and qualify leads on a phone.

sellers whose products sit clearly inside Stripe's published rules and who want self-serve signup with no monthly fee

Stripe

Stripe is the pick if your offer fits its published restricted-business list and you want to charge cards without a merchant account application or a monthly fee. It is a payment facilitator, so approval comes at signup and the risk review comes once volume shows up, which is the trade a supplement or continuity seller feels first.

From

supplement, continuity, CBD and other restricted-category sellers who need an underwriter to accept their category before they run volume

High-risk merchant account

A high-risk merchant account is the pick if you sell in a category that payment facilitators restrict, or you have already been closed by one, and you would rather pass underwriting up front than be reviewed after the money lands. You pay for that with quote-based rates, a possible reserve and a slower approval.

From

Ethoca and Verifi alerts plus automated dispute filing in one account

Chargeflow

Chargeflow is the pick if you want Ethoca and Verifi alerts and automated representment from one vendor. It is a real company with self-serve signup, a Shopify app and a Stripe marketplace listing. Audit the alert invoice and the automation win rate before you turn both on.

From

Usage-based

Use these paths when Stripe has paused your payouts and another self-serve signup would hit the same rules.

Stripe alternatives for high-risk sellers

Start with ElasticFunnels if you run paid ads and you have, or are getting, NMI merchant accounts to split the first sale. Use ClickBank or Digistore24 if a marketplace should own the processor relationship, and Checkout Champ or Konnektive if the volume is already on a direct-response platform.
