AI & automation for accounting firms

The work that eats an accounting practice is rarely the accounting. It is the chasing: client onboarding, data that arrives in the wrong format, reconciliations that almost-but-not-quite match, the reporting pack that someone rebuilds by hand every month. That is the admin worth automating first.

The difference is how deep the integration goes. We build directly against Xero's and Stripe's APIs, across many of their endpoints, not the off-the-shelf marketplace connectors that cover the common case and stop at the edges. That means workflows shaped to how your practice actually runs, wired into the ledger and the payment rails you already use.

We are honest about where automation does not belong. Judgment, advice, and the client relationship stay with your people. The goal is to give them their week back, not to put a bot between them and the work that earns the fee.

/ What's included

Native Xero integration

Built directly against the Xero API across many of its surfaces, not a marketplace connector. Client and ledger data flows where it needs to, on your practice's terms.

Payment and reconciliation automation

Stripe and bank feeds wired into the workflow so the routine matches itself and only the genuine exceptions reach a person.

Practice workflow automation

Onboarding, document collection, and the monthly reporting pack automated end to end. The repetitive glue between systems that nobody should assemble by hand.

Measurement

Every automation tied to hours back or errors removed, agreed before we build. You know what it is worth before it exists.

/ Engagements & pricing

Discovery

Under $4,000 NZD fixed

Small, tightly scoped. Produces a prioritised map of where automation pays in your practice and what it would cost to build. A decision document, not a presentation.

Automation sprint

$5,000 to $25,000 NZD

One bounded problem, fixed price, working software at the end. Scope is locked before the build starts so there are no surprises on the invoice.

Baseline retainer

$4,000 to $8,000 NZD / month

A steady cadence through the backlog, re-prioritised against results each month. Suited to practices with a long list of manual processes to work through systematically.

Frequently asked questions

Do you work with Xero?
Yes, deeply. We integrate directly against the Xero API rather than relying on the app marketplace, which means we can automate workflows the standard connectors do not reach. We work with Stripe the same way for payments.
Can you build beyond what the Xero app marketplace offers?
That is most of what we do. Marketplace apps cover the common case and stop at the edges. Building against the API directly means the automation fits your practice instead of forcing your practice to fit the app.
What does this cost?
A scoped discovery is fixed under $4,000 NZD. A bounded automation sprint runs $5,000 to $25,000 NZD depending on complexity. Monthly retainers sit between $4,000 and $8,000 NZD. Every engagement is quoted before any build begins.
Is our clients' data safe?
Integrations use the platforms' own authenticated APIs and scoped permissions, with access limited to what a given workflow needs. Data handling is agreed in writing before anything is connected.
