Payment Integration

Payments That Capture Every Dollar

We build payment integrations that handle the full complexity of SaaS billing — subscription lifecycle, metered charges, multi-currency, tax calculation, and dunning that recovers revenue before failures become churn.

Why It Matters

Why Payment Integration Is Where SaaS Products Lose Money Silently

The most common mistake SaaS businesses make with payment integration is treating billing as a basic feature rather than a revenue-critical system. A Stripe integration that handles the happy path — successful card payments for new subscribers — is straightforward to build in a few days. The complexity is in the edge cases: mid-cycle plan upgrades that must prorate correctly, failed payments that need a configurable retry schedule rather than an immediate cancellation, disputes that require evidence submission within a tight window, and tax calculations that vary by customer jurisdiction and your registration status in each one.

The financial cost of getting these edge cases wrong is invisible until the business is at a scale where they're occurring regularly. An upgrade that charges the wrong proration creates an accounting discrepancy and an angry customer. A failed payment that triggers an immediate cancellation rather than a dunning sequence churns a customer who intended to stay. A missed dispute response costs you the transaction amount plus a dispute fee. At 500 subscribers, these failures happen weekly. At 5,000, they happen daily.

Our payment integration process starts with a billing requirements analysis that maps every payment scenario your product needs to handle before a single line of billing code is written. Upgrade paths, refund policies, tax requirements, currency needs, and dunning logic are all documented in advance. The implementation is then tested against every edge case in Stripe's test environment — not assumed to be correct and discovered in production when a customer reports a billing error.

The accounting reconciliation layer is the piece that most payment integrations skip and most finance teams eventually demand. Stripe's revenue data needs to match your accounting system's records, deferred revenue needs to be tracked correctly for accrual-basis reporting, and refund events need to be recorded in both systems consistently. We build the reconciliation automation that keeps these systems aligned so your finance team can close the books without a manual reconciliation exercise every month.

What You Receive

Exactly What We Deliver

No vague deliverables. Every Payment Integration Systems engagement comes with a clear set of files, assets, and outputs.

Stripe Billing Integration

A complete Stripe Billing implementation covering subscription lifecycle, plan tiers, trial management, and payment method handling. Tested against every billing edge case before production go-live.

Dunning Automation System

A configured failed-payment recovery system with Stripe Smart Retries, customer email sequences, and in-app payment update prompts. Designed to recover as many failed payments as possible before they result in involuntary churn.

Multi-Currency & Tax Setup

Stripe Tax configuration for automated jurisdiction-based tax calculation, plus local payment method activation for your target markets. Removes friction for international customers and keeps tax compliance accurate as you scale.

Revenue Reconciliation System

Automated reconciliation between Stripe and your accounting system with deferred revenue tracking for annual subscribers. Keeps your finance team's records accurate without manual monthly reconciliation work.

PCI-Compliant Checkout

A tokenised payment flow where card data is handled entirely within Stripe's infrastructure, keeping your PCI compliance scope at SAQ A. Includes 3D Secure 2 authentication for regulated markets.

Billing Admin Tooling

Internal tools for processing refunds, generating manual invoices, applying credits, and reviewing dispute status. Gives your operations team the ability to handle billing edge cases without engineering involvement.

Our Process

From Kickoff to Results in 4 Steps

A clear, structured process so you always know where things stand — no guessing, no surprises along the way.

Billing Requirements Analysis

We map every payment scenario your product needs to handle — pricing plans, upgrade paths, refund policies, tax requirements, and currency needs — before configuring anything.

Stripe Configuration & Integration Build

Stripe products, prices, and subscription logic are configured, and the integration layer between your product and Stripe is built covering every billing event and webhook.

Edge Case Testing

Every billing edge case — mid-cycle upgrades, failed payments, trial conversions, refunds, and disputes — is tested in Stripe's test environment before go-live.

Accounting Integration & Reconciliation

Revenue data from Stripe is reconciled against your accounting system, and automated reports are configured so your finance team always has accurate revenue records.

Common Situations We Fix

Problems We've Seen — and How We Prevent Them

These are real situations that come up. Here's how our process makes each one impossible.

Failed payments are immediately cancelling paying customers

A configured dunning system with Stripe Smart Retries and a customer communication sequence replaces immediate cancellation with a structured recovery window. Most failed payments result from temporary card issues that resolve on retry — dunning is designed to recover as many as possible before churn occurs.

Billing errors on plan upgrades are creating accounting discrepancies

Proration logic tested against every mid-cycle upgrade scenario in Stripe's test environment before go-live ensures customers are charged correctly regardless of when in the billing cycle they change plans. Accounting reconciliation automation keeps Stripe and your books aligned without manual correction.

International customers are dropping off at checkout

Local payment method activation — iDEAL, SEPA, BECS, and others — and multi-currency pricing remove the friction that causes international customers to abandon at the payment step. Stripe's Payment Element renders the most relevant payment options automatically based on customer location.

Finance team spends days reconciling Stripe and accounting records

Automated revenue reconciliation syncs Stripe billing events to your accounting system in real time, with deferred revenue tracked correctly for annual subscriptions and refunds recorded consistently in both systems. Month-end close becomes a review, not a manual reconciliation exercise.

Why It Works

What Makes Our Approach Different

We don't just deliver a project — we make sure it actually performs for your business after launch.

No Revenue Lost to Payment Failures

A well-designed dunning system can recover a significant share of failed payments that would otherwise result in involuntary churn. A well-configured retry schedule, combined with customer email and in-app notifications, helps keep revenue you earned but failed to collect.

PCI Compliance Without PCI Scope

Stripe's tokenisation architecture means your servers never store or process raw card data, keeping your PCI compliance scope to the minimum. We implement payment flows that maximise this protection — never routing card data through your application layer when Stripe can handle it natively.

Sell to Customers Anywhere in the World

Multi-currency support and local payment method coverage — iDEAL in the Netherlands, BECS in Australia, SEPA in Europe — removes friction for international customers who prefer not to pay in USD or with a credit card. Expanding your addressable market requires payment infrastructure that serves customers the way they want to pay.

Revenue Data Your Finance Team Can Trust

Deferred revenue tracking, accurate refund handling, and automated reconciliation with your accounting system mean your revenue figures are always accurate. When audit time comes or you're preparing financial statements for investors, your revenue data is correct and explainable — not the subject of hours of manual reconciliation.
