Payment Processing & E-Commerce Integration
(Stripe, PayPal & PayPal Enterprise Payments, Set Up for You)
A checkout that works, on a merchant account you own
We connect your website to a real payment platform, turn on the payment methods your customers actually use, and hand you a checkout that works. You keep ownership of your merchant account and your money. We handle the configuration, testing, and launch.

Start by choosing a platform
Every integration runs on one of three platforms. The right one is decided by which payment methods your customers expect, not by preference. Here is what each one is and who it suits.
Stripe
The strongest option for tiered plans and recurring billing. Proration, plan upgrades, dunning, and a hosted customer portal are built in. Cash App Pay and ACH are both available here.
Does not support Venmo. US Stripe accounts cannot accept PayPal.
PayPal Checkout
The fastest route to accepting PayPal and Venmo. Requires a PayPal Business account. Venmo appears on your existing PayPal buttons once enabled.
Does not support ACH bank debit or Cash App Pay.
PayPal Enterprise Payments
PayPal's full processing platform. Cards, PayPal, Venmo, Apple Pay, Google Pay, and ACH from a single integration. Separate application and underwriting.
Does not support Cash App Pay. Subscription tooling is lighter than Stripe's.
The one rule that decides most projects
No single platform offers both Venmo and Cash App Pay. Cash App Pay exists only on Stripe. Venmo exists only on PayPal and PayPal Enterprise Payments. If your customers expect one of the two, that requirement chooses your platform for you. If you need both, you would run two processors side by side, which we can scope separately.

Platform processing rates
These are the platforms' own published US rates, charged directly to you on each transaction. We do not mark them up, and we do not collect them. None of these platforms charge a setup fee, a monthly fee, or a minimum processing requirement.
Rates are subject to change by the platform at any time. Confirm current pricing on the provider's own pricing page before relying on these figures.
Stripe
PayPal Checkout
PayPal publishes rates by product and account type. We confirm your exact rate against your account during onboarding.

Businesses processing roughly $80,000 a month or more can request negotiated interchange-plus pricing.
PayPal Enterprise fees pageHow it works
You own the merchant account. You create it, you control it, and you can revoke our access at any time. We never ask for your banking details, tax identification documents, or account passwords. Every platform we work with supports proper delegated access, and that is what we use.
-
01
Discovery call
We look at who your customers are, what you sell, whether you bill once or on a recurring basis, and which payment methods your buyers expect. That conversation determines your platform.
-
02
You create the account
You sign up directly with Stripe, PayPal, or PayPal Enterprise Payments and complete their verification using your own business and banking information. We send you a checklist and stay on the phone if you want a hand, but the credentials stay yours.
-
03
You grant us access
You invite us as a team member with the permissions the work requires. No shared passwords. When the project ends, you remove us in a single click.
-
04
We build and test in sandbox
Checkout integration, payment method configuration, tax and currency settings, receipts, and webhooks, all built against the platform's test environment first. Apple Pay domain verification and wallet eligibility are confirmed here.
-
05
Live verification
We run a real transaction on every enabled method, on desktop and mobile, and confirm the funds land in your account and the money reconciles in your dashboard.
-
06
Handoff
A walkthrough of your dashboard: where to find payouts, how to issue a refund, what a dispute looks like, and who to call. You leave knowing how to run it.
