Bespoke Apps & Integrations

When the off-the-shelf app does not quite fit, we build the one that does.

We have an in-house developer. So when your business does something a little different, we can build the bespoke piece that captures it properly and plugs it straight into Xero.

Where Xero Meets Your Business Systems

Most bookkeepers stop at the edge of Xero. We do not. Every business records its costs, raises its invoices and tracks its work in a slightly different way, and the more interesting the business, the less likely it is that an off-the-shelf app will cover the lot. That is the gap our developer fills, and it is what lets us turn a Xero file and a few moving parts into one joined-up system.

What we build

Built Around the Way Your Business Works

Off-the-shelf software can only take you so far. We build the tools, portals, dashboards and integrations that connect your day-to-day operations with Xero, giving you cleaner data, smoother processes and one reliable view of the numbers.

Bespoke web apps & internal tools

Custom-built apps tailored to how your business actually works — capturing the inputs your team needs to record, in the format that fits, on whatever device they happen to be using.

Custom invoicing & billing portals

Capture the right job inputs, generate the invoice the way your customers expect, and push it straight into Xero with the right tracking, tax codes and supporting detail attached.

Job & project costing tools

Job costing built around your work, mapped onto Xero’s projects and tracking categories so the management view and the books stay in lockstep.

Operational dashboards

Sales, ops and finance numbers brought together into a single view — so you stop comparing three reports that almost agree, and start running the business off one set of figures.

Automations & integrations

We connect Xero to the other systems you already use — CRM, e-commerce, scheduling, stock, payment platforms — so the same number never gets typed in twice.

Data clean-up & migration

When you are moving onto Xero or restructuring a messy file, we write the migration and clean-up scripts that get the data across cleanly and the history right.

Built around your business

Most practices will tell you to change your business to fit your software. We start the other way around. We sit down with you, map how the work really flows, and find the friction, sometimes the answer is a setting in Xero or an app from the marketplace, and we will tell you so. When it is not, we scope a bespoke build properly: what it does, what it does not, what it costs and how long it takes.

Every build talks to Xero through the official API, real two-way integration, not a CSV export at the end of the month, and once it is live, the bookkeeping team takes the baton. They know the tool, they know your file, and the two are designed to work together from day one.

What you get

  • A discovery conversation with our developer and a bookkeeper in the room together
  • A scoped, fixed-fee build wherever possible — clear deliverables, clear timeline
  • Real two-way Xero integration through the official API, with full audit trail
  • A bookkeeping team already trained on the tool the day it goes live
  • Ongoing care and small tweaks wrapped into your original build fee — no surprise invoices.

HOW TO GET IN TOUCH

Need Xero bookkeeping support?

If something in your day-to-day is held together with sellotape and exported spreadsheets, it is probably worth a 20-minute conversation. We will tell you whether a bespoke build is the answer, or whether the answer is simpler than you think.
