How to Automate Your BAS Prep: Xero + Dext for Australian Small Business (2026)

If BAS time still means digging through emails, chasing missing receipts, and manually reconciling transactions in Xero, you’re doing it the hard way.

The problem isn’t the BAS itself: it’s the four to six hours of prep work that happens beforehand. Most of that work can be automated. Here’s how.

What the Automation Looks Like

The core workflow:

1. Dext captures your receipts and invoices (via phone photo, email forward, or bank feed)
2. Dext reads and extracts the data: supplier, amount, GST, date: and codes it to the right account
3. Xero receives the coded transactions automatically
4. When BAS time comes, Xero’s GST report is already accurate

You’re removing the manual data entry step entirely. Instead of re-typing receipt information into Xero, the data flows through automatically.

What You Need

• Xero (any plan works. Xero Starter covers most sole traders)
• Dext Prepare (formerly Receipt Bank): pricing starts around AU$30/month for sole traders; visit their site for current Australian plans
• A smartphone with the Dext app installed

You don’t need a bookkeeper to set this up, though they’ll appreciate the cleaner records when you do.

Step-by-Step Setup

Step 1: Connect Dext to Xero

In Dext, go to Settings > Connections and select Xero. Log in and authorise the connection. Once done, Dext can push transactions directly into your Xero account’s Draft Bills or Spend Money section.

Step 2: Set Up Your Account Mapping

Tell Dext which expense types map to which Xero accounts. For example: petrol receipts go to Motor Vehicle Expenses. You do this once during setup. Dext learns your preferences and gets faster to process over time.

Step 3: Capture Receipts as They Happen

Open the Dext app, take a photo of the receipt. Dext reads the text and extracts the key data within seconds. You can also email receipts to a unique Dext address: useful for PDF invoices from suppliers.

Step 4: Review and Publish to Xero

In Dext’s inbox, you’ll see extracted transactions ready to review. If the amounts and categories look right, click Publish. They appear in Xero within minutes.

Some businesses review daily (2-3 minutes). Others do it weekly. Either works.

Step 5: Reconcile in Xero as Usual

When bank transactions come through, they’ll already match the Dext-published bills or receipts. Xero’s smart matching handles most automatically. You’re confirming matches rather than entering data.

Set up rules for recurring transactions

This is where Xero earns its keep. Both Xero and MYOB let you create bank rules — automatic categorisation for transactions that follow a pattern.

Examples:

• Anything from “SPOTIFY AUSTRALIA” → Entertainment, 0% GST
• Anything from “AGL ENERGY” → Utilities, 10% GST
• Anything from “AWS” → Software/Cloud Services, 10% GST
• Rent payments → Rent, 10% GST

After a few months, 70–80% of your transactions categorise themselves. You’re reviewing and approving, not typing.

Use Zapier to close the gaps

Not everything has a native integration. Zapier connects the tools that don’t talk to each other.

Stripe or Square payments → Xero invoice
Connect your payment processor to Xero via Zapier. Every sale creates an invoice automatically. GST is captured at the point of sale, not reconstructed later.

WooCommerce or Shopify → Xero
Both platforms have direct Xero integrations, so no Zapier needed for most setups. But if you’re using a more custom configuration, Zapier handles it. Orders sync, refunds sync, sales figures stay current.

Gmail receipt forwarding
Set a filter in Gmail to auto-forward any email with “invoice” or “receipt” in the subject line to your Dext address. Zapier can handle the routing if you want conditions beyond what Gmail supports natively.

What this costs in practice

A realistic setup for a small service business:

For most sole traders and small businesses: Xero Starter + Dext + Zapier Free is around AU$62/month. The time saved — two to four hours per quarter at minimum — pays for itself at any reasonable hourly rate.

Before Each BAS Lodgement

With this workflow running, BAS prep looks like this:

1. Check Xero’s GST report: confirm the figures look right
2. Review any unmatched transactions (there are usually a few)
3. Run the BAS through Xero’s lodgement tool, or share with your accountant

Total time: 30-60 minutes instead of half a day.

What About MYOB Users?

Dext connects to MYOB in much the same way: go to Dext > Connections > MYOB and follow the prompts. MYOB also has its own mobile capture feature built into the app if you’d rather not pay for a separate tool.

Alternatives to Dext

• Hubdoc: owned by Xero, included with Xero’s Growing and Established plans. Less powerful than Dext but free if you’re already on a qualifying Xero plan. A solid starting point.
• AutoEntry: similar to Dext, slightly lower price point, less common in Australia
• Xero Capture: basic receipt capture built into the Xero mobile app, no extra cost

For most sole traders and micro businesses, start with Hubdoc or Xero Capture before deciding whether Dext’s additional features are worth the cost.

What This Won’t Automate

A few things still need a human:

• Business vs personal split: if you use one card for both, you’ll still need to flag personal transactions
• Mileage claims: need a separate log (a Google Sheet or dedicated logbook app works fine)
• Complex payroll. Xero Payroll handles the calculations, but setup still needs a bookkeeper to get right the first time

Worth Doing Before June 30

With 9 weeks until EOFY, there’s still enough time to get this running and have clean records by June 30. Setup takes around two hours the first time. The time savings start immediately after.

If you’re aiming for a faster BAS this quarter, this is the single most effective change you can make to your bookkeeping workflow.
