Payments That Just Work, So You Can Stop Thinking About Billing

Checkout, subscriptions, marketplace payouts, Apple Pay and Google Pay: we've built all of it on Stripe, across booking platforms, subscription products, and consumer apps. You get reliable billing infrastructure without building it from scratch.

See What We Build

Shipped repeatedly

Stripe integrations across four separate client platforms.

18% lift

Increase in in-app payments after a Stripe rebuild for BXR.

Subscriptions ready

Recurring billing, trials, upgrades, and dunning.

Mobile-first

Apple Pay and Google Pay built in, not bolted on.

What We Actually Build On Stripe

Payments infrastructure has to be correct the first time. We've built each of these patterns for products already handling real transaction volume.

CHECKOUT

Custom checkout flows


Branded checkout experiences that reconcile cleanly with Stripe, instead of routing customers through a generic hosted page.

BILLING

Subscription & recurring billing


Plans, trials, upgrades, downgrades, and failed-payment recovery, built on Stripe Billing and tracked correctly in your application.

MARKETPLACE

Multi-party payouts


Stripe Connect integrations that split a single payment across venues, providers, or sellers automatically.

MOBILE

Apple Pay & Google Pay


Native mobile payment methods integrated into iOS and Android apps, reducing checkout friction on the devices your users already carry.

MIGRATION

Processor migrations


Moving billing to Stripe from another processor, without disrupting active subscriptions or forcing customers to re-enter payment details.

RECONCILIATION

Reporting & reconciliation


Syncing Stripe transaction data into your accounting, CRM, or internal reporting, so finance isn't reconciling by hand.

Why Payments Integration Is Worth Getting Right

Stripe's API is well documented. The application logic wrapped around it, the part that decides what a user can access and when, is where most billing bugs actually live.

Subscription state is easy to get wrong

Trials, upgrades, and failed renewals all change what a user should see. Getting this out of sync with Stripe means users with access they shouldn't have, or without access they paid for.

Checkout friction costs conversions directly

Every extra step or unsupported payment method at checkout is a measurable drop in completed purchases, especially on mobile.

Marketplace payouts need to be exact

Splitting payments across multiple parties has to be correct on every transaction. Manual reconciliation doesn't scale past a handful of payouts a month.

"Building features, including subscription and payment capabilities. Our software enables clients to conduct due diligence on their vendors. NUS helped us upgrade our features and update the UI. Overall, we've been with NUS for over 5 years, and they've always been accommodating and fair. We would recommend them to anyone looking for quality work, especially if on a strict budget."

How An Engagement Usually Starts

We start with your actual billing model and current setup, not a generic payments checklist.

AUDIT

We map your billing model and current stack

01

A review of how you charge customers today, what's live in Stripe or another processor, and where the gaps are.

SCOPE

You get a concrete plan, not a vague proposal

02

Which flows get built, checkout, subscriptions, payouts, and how they connect to your existing user and account model.

BUILD

Built and tested against Stripe's test environment

03

Every flow is validated against Stripe's test mode, including edge cases like failed payments and disputed charges, before going live.

SUPPORT

Ongoing support as your billing model evolves

04

New plans, new markets, or new payment methods don't have to mean re-architecting your payments layer.

Questions Clients Usually Ask

What kind of Stripe integrations do you build?

PlusMinus
One-time checkout, recurring subscription billing, marketplace payments that split funds between multiple parties, and mobile payments through Apple Pay and Google Pay. We've built all of these across booking platforms, EdTech subscriptions, and consumer apps.

Can you add subscriptions to a product that only takes one-time payments today?

PlusMinus
Yes. This is a common request: a product launches with simple checkout, then needs recurring billing, plan upgrades and downgrades, trials, and dunning for failed payments. We handle both the Stripe-side setup and the application logic that has to track subscription state correctly.

We're a marketplace or booking platform. Can Stripe handle paying out multiple parties?

PlusMinus
Yes, through Stripe Connect. We've built this for a booking platform that needed to collect payment from a customer and route the correct share to venues or providers automatically, without manual reconciliation.

Do you handle PCI compliance and security?

PlusMinus
We build with Stripe's hosted and pre-built UI components wherever possible, specifically so raw card data never touches your servers, which keeps your PCI compliance scope minimal. Where a custom flow is required, we follow Stripe's recommended architecture for handling sensitive data.

Can you migrate us from another payment processor to Stripe?

PlusMinus
Yes. Migrations need care around active subscriptions, stored payment methods, and historical transaction data, so customers don't experience a billing gap or have to re-enter their card during the switch.
