What is Authorize.net?
Authorize.net is one of the longest-running payment gateways in the US market, now owned by Visa. It connects websites and applications to US merchant accounts, with card processing, eChecks/ACH, customer profiles for stored payments, and recurring billing. For businesses with US merchant relationships, it's frequently the gateway that's already there.
Why Authorize.net matters for your business
If you're a NZ or AU business selling into the US — or you've acquired a product that runs on it — Authorize.net is often a fact of life rather than a choice. It's stable and bank-trusted, but its APIs show their age, which makes clean integration work matter more, not less. And when the time comes to modernise or consolidate onto Stripe, that migration deserves engineering care: stored customer profiles and recurring billing don't move themselves.
How we help you with Authorize.net
Integration & modernisation
Accept.js tokenised payments, webhooks and customer profiles — integrated to current standards, not 2009's.
Recurring billing (ARB & CIM)
Subscriptions and stored-card flows built on Authorize.net's profile system, PCI-sensibly.
Gateway migrations
Moving to or from Authorize.net — customer profiles, subscriptions and history migrated without losing a beat.
Legacy rescue
Inherited an old Authorize.net integration nobody understands? We'll map it, stabilise it and document it.
The staying power — integrations we built against Authorize.net years ago still process daily. We're equally comfortable keeping it healthy (webhooks, Accept.js tokenisation, fraud settings) or planning a zero-downtime migration to a modern stack when that's the right call. We'll tell you which honestly.
