Payment systems integration

Online payments that line up with the records, bookings, invoices and customer accounts around them.

Taking payments online is not the hard part. Making the payment line up with the booking, invoice, customer record, subscription, refund and bank reconciliation is where businesses get caught.

Rangefront Labs integrates payment processors into websites, apps, portals and internal systems, then connects payment status to the records your team actually uses.

Where payment work gets complicated

A basic checkout can be enough for a simple sale. Custom payment work makes sense when the money has to trigger something else.

That might mean:

  • Deposits, part-payments or staged payments.
  • Subscription billing, renewals and failed-payment states.
  • Booking payments that affect capacity, calendars or job records.
  • Customer portal payments with invoice history and account status.
  • Refunds, cancellations, credits and manual review.
  • Payment links, receipts and internal approval before payment.
  • Payment status syncing into Xero, a CRM, a job system or a reporting database.

The payment provider is only one part of the system. The business rules around the payment are usually the real project.

What we build

Depending on the job, a payment systems project might include:

  • Hosted checkout or embedded payment flows.
  • Payment gateway and processor integration.
  • Webhook handlers for payment success, failure, refunds and disputes.
  • Subscription and renewal logic.
  • Admin screens for failed payments, refunds and manual follow-up.
  • Customer account screens with payment history and invoice status.
  • Payment status sync to finance, CRM, booking, portal or internal systems.
  • Reporting that shows what has been paid, what failed and what needs review.

We usually use established payment providers for the money handling. The custom engineering sits around the flow: what the customer sees, what staff can manage, what records update, and how failures are surfaced.

We run subscription billing in our own products, not just client work. YawnTales is a subscription SaaS product where families pay on a recurring plan, with member accounts, renewals and failed-payment handling behind it, so the recurring-billing flows we build for clients are the same ones we operate ourselves.

The providers we wire up

Australian businesses rarely run one payment method any more. A typical online store takes cards through Shopify Payments, Stripe or Square, keeps PayPal for the customers who will not check out without it, offers Apple Pay and Google Pay because they remove a whole form on a phone, and adds Afterpay, Zip, Klarna or Humm because shoppers ask for them by name. Businesses that started with a bank or an EFTPOS terminal often come to us already on eWAY, Tyro, Fat Zebra or Windcave, and recurring billing usually means Stripe subscriptions, GoCardless or Ezidebit for direct debit.

We work with all of them. The integration is not the interesting question, though. What matters is which ones are worth having, because buy now, pay later costs a merchant roughly 4% to 6% of the sale where card processing sits nearer 1.7% plus a few cents. On healthy margins that fee buys bigger baskets and customers who would not have bought at all. On thin margins it takes the profit off every order, and it usually takes months for anyone to notice. We will give you the numbers for your margins before you switch anything on, including how surcharging rules apply to what you are charging customers.

Then there is the mess after the sale. Every provider settles on its own schedule, nets out its own fees, and reports refunds and chargebacks its own way, so a business running four payment methods hands its bookkeeper four sets of numbers that do not match the order list. Making payouts, fees, refunds and disputes land correctly in Xero or MYOB is most of the work, and it is the part that gets skipped until the first BAS makes it someone’s problem.

Processor choice and payment flow

Sometimes a hosted checkout is the right move because it reduces security scope and gets the customer through payment cleanly. Sometimes the payment flow needs to sit inside a larger app, portal or booking process. Sometimes the provider is already chosen by a bank, platform or existing system.

We start with the business flow: who pays, when they pay, what changes after payment, what happens when it fails, and where the final record needs to land. From there we choose the processor path that fits.

Payments need admin tools

The customer-facing payment screen is only half the work. Staff still need to see failed payments, resend payment links, issue refunds, check webhook history, reconcile records and answer customer questions without digging through processor logs.

That is why payment integration often overlaps with customer portals, booking systems, SaaS and MVP product development and Xero, CRM and operations integration.

Start with the money trail

Send the current checkout, invoice flow or spreadsheet that tracks payment status today. We will map what should happen before payment, what should happen after payment, and which records need to agree.

Common questions

Stripe, Square, PayPal, Braintree, Adyen and Airwallex on the card side, Australian gateways like eWAY, Tyro, Fat Zebra and Windcave, buy now, pay later through Afterpay, Zip, Klarna, Humm and Shop Pay, wallets like Apple Pay and Google Pay, and direct debit through GoCardless or Ezidebit. If a provider exposes an API, hosted checkout, webhook or reporting feed, we can work with it.

Yes, and we will tell you what they cost you. Buy now, pay later charges merchants roughly 4% to 6% of the sale against about 1.7% plus a few cents for cards. That can be money well spent when it lifts basket sizes or wins customers who would not have bought, and it can quietly eat your margin when it does not. We will help you work out which side of that line you are on before wiring it up.

Yes. We can build subscription flows, renewal states, failed-payment handling, customer account screens and admin visibility around billing.

Yes. Payment status can update finance, CRM, booking, portal or job records, with clear rules about which system owns each field.

Almost never. The custom work is usually the checkout flow, webhook handling, admin screens, reconciliation and integration around an established payment provider.

Yes. We can audit the checkout, webhooks, logs, failed states and connected records, then fix the parts that are causing manual work or missing payments.
