Xero Bookkeeping Experts

ATS is a certified Xero partner helping businesses get the most out of Xero.

A Certified Xero Partner

ATS Bookkeeping & Advisory Services is a recognized Xero partner, and our team holds active Xero certifications to back it up. Being a Xero partner means more than displaying a badge. It means we have completed Xero's formal training, we stay current with product updates as they ship, and we have direct access to the partner support channels that most users never see.

You get people who use Xero every day, not once a quarter. We know the shortcuts, the common setup mistakes, and the features worth investing time in. Whether you are starting fresh with a new Xero file, cleaning up one that has drifted, or building a reporting rhythm that helps you make decisions, we bring that hands-on experience to every engagement.

Our Xero clients span construction companies tracking job costs, healthcare practices managing complex revenue, law firms, freight and logistics operators, and nonprofits with specific filing requirements. Every one of them runs on Xero, and every one of them works with the same team that knows the platform inside and out.

Why Xero

Xero gives small businesses the visibility, automation, and reliability that used to be reserved for much larger companies. Here's what that looks like day to day.

Real-Time Financial Picture

Your books update as transactions come in, so you can check profit, cash, and outstanding invoices whenever you need to, not weeks after the fact.

Connected Bank Feeds

Xero pulls transactions directly from your bank accounts, credit cards, and payment processors. Less data entry, fewer gaps, cleaner month-ends.

Cloud Access from Anywhere

Log in from your laptop, tablet, or phone. Your accountant sees the same file you do, so conversations about the numbers actually happen in the numbers.

Professional Invoicing

Send branded invoices, track what's outstanding, and accept online payments. It all lives inside Xero, with the payment flowing straight back into your books.

Reports You Can Act On

Profit and loss, balance sheet, cash flow, and custom reports are a click away. No waiting for month-end to know where the business actually stands.

Secure and Reliable

Bank-grade encryption, two-factor authentication, and automatic backups. Your financial data is protected, versioned, and always recoverable.

What We Do in Xero

From first-time setup to ongoing bookkeeping and advisory, here's how we work with clients inside Xero.

Xero Setup

We set up your Xero file from scratch, including a chart of accounts tailored to your business, connected bank feeds, configured tax codes, and users added with the right permissions.

Monthly Bookkeeping in Xero

Categorization, reconciliation, and month-end close every month. Your Xero file stays clean, current, and ready for tax time or a lender review.

Xero Health Check

Already using Xero but not sure it's set up correctly? We review your chart of accounts, feeds, and historical transactions and tell you exactly what to fix.

Xero Training for Your Team

We train your in-house staff on the Xero features they actually use, like raising invoices, approving bills, and running reports, so they can work alongside us confidently.

Payroll Integrated with Xero

Run payroll so wages, taxes, and benefits flow straight into your Xero books. Less reconciling, fewer errors, and one source of truth for your financials.

Advisory Built on Xero Reports

Your Xero data drives budgets, cash-flow forecasts, and growth plans. We turn your real-time numbers into decisions you can actually act on.
