Platform notes
Carrd: a payment-enabled form inserts a Stripe Checkout screen between submission and processing. You use either a Price ID set up in Stripe or a custom price, and enter your Stripe API keys. It requires Pro Plus. On cheaper plans, Carrd's plan page lists Stripe, PayPal and Gumroad widgets from Pro Standard, which its widget docs describe as a Stripe Checkout button, a PayPal button and a Gumroad buy button. [1][13][15]
Webflow: the Ecommerce plans list Stripe, PayPal and Apple Pay, and a transaction fee that is "in addition to Stripe or Paypal processing fees": 2% on Standard and 0% on Plus and Advanced. Standard allows 500 ecommerce items. [2]
systeme.io: Stripe and PayPal connect under Settings, Payment Gateways, and the pricing page lists 0% transaction fees on all plans. PayPal needs a Business account and supports 25 currencies. Stripe card payments have no merchant restriction beyond Stripe's own country list, but Apple Pay is blocked for Stripe accounts registered in India and Klarna needs a Klarna-supported country. The Free plan can take payments, but systeme.io's terms limit free accounts to USD 10,000 in lifetime sales; after that you get 3 days to upgrade before payment pages stop accepting new sales. [3][4][5][14]
Shopify: third-party transaction fees apply to all transactions through third-party gateways, "even when Shopify Payments is activated", except that PayPal is exempt if Shopify Payments is your primary provider. US stores whose sales tax is managed by Shopify cannot use third-party providers. If your country is not supported by Shopify Payments, you must use a third-party provider. [6][7][8]
Framer: the pricing page lists no checkout or ecommerce feature, so selling from a Framer site means linking to a hosted checkout from your payment provider. [9]
Processor fees you pay regardless
Stripe's US standard rate is 2.9% plus 30 cents per successful domestic card transaction, plus 1.5% for international cards and 1% if currency conversion is needed. PayPal's US page (last updated 1 October 2026) lists PayPal Checkout at 3.49% plus a fixed fee, standard card payments at 2.99% plus a fixed fee, and a 0.49 USD fixed fee for commercial transactions in US dollars. Shopify Payments on Basic lists online card rates from 2.9% plus 30 cents. [10][11][7]
Worked example: $1,000 a month in sales
Assumptions: 20 orders of $50, all US domestic cards, cheapest plan that can take payment, plan prices on yearly billing converted to a monthly figure, tax excluded. systeme.io is shown on Startup because at this volume the Free plan's USD 10,000 lifetime sales cap would be reached in 10 months. Stripe fee: 2.9% of $1,000 is $29, plus 20 times $0.30 is $6, so $35. PayPal Checkout instead: 3.49% is $34.90 plus 20 times $0.49 is $9.80, so $44.70. [1][2][3][13][14][7][9][10][11]

| systeme.io Startup with PayPal | $17.00 | $0 | $44.70 | $61.70 |
| Shopify Basic with Shopify Payments | $29.00 | $0 | $35.00 | $64.00 |

Checklist before choosing a gateway
- Confirm the processor supports your country and business type before you design checkout. [5][8]
- On Shopify, decide on Shopify Payments first; a third-party gateway adds 2% on Basic. [6][7]
- On Webflow, compare Standard's 2% against Plus's higher plan price at your real sales volume. [2]
- Add 1.5% to Stripe estimates if many buyers use non-US cards, and 1% more for currency conversion. [10]
- Check the processor's restricted business list for your niche before launch. [12]
- Run one live test purchase and one refund before announcing the site.
Questions before you decide
Can I accept PayPal on Carrd?
Yes, through a widget. Carrd's plan page lists a PayPal widget, along with Stripe and Gumroad, from Pro Standard. Payment-enabled forms on Pro Plus are different: they use Stripe Checkout only, and the payment must succeed before the form is processed.
Does Webflow charge a transaction fee?
Webflow's Ecommerce Standard plan lists a 2% transaction fee in addition to Stripe or PayPal processing fees. The Plus and Advanced plans list 0%.
Does Shopify charge extra if I use Stripe or another gateway?
Yes. Shopify's pricing page lists third-party transaction fees of 2% on Basic, 1% on Grow and 0.6% on Advanced. PayPal is exempt when Shopify Payments is your primary provider.
Does systeme.io take a cut of sales?
systeme.io's pricing page lists 0% transaction fees on every plan. You still pay Stripe or PayPal their own processing fees.
