Practical AI for small and medium businesses

The short version

What AI does

A capture tool reads each supplier bill and receipt, extracts the supplier, date, amounts and invoice number, applies your supplier rules and publishes routine items to Xero, MYOB or QuickBooks. Bookkeepers review new suppliers and exceptions.

What it costs

About $13,500 to set up and $1,425 a month to run with AI automation.

What it saves

Pays for itself in about 5 months, then about $97,900 a year in staff time, after running costs.

This is an illustrative example, not a past client project. It uses AI features the vendors document today and our cost model. Your own figures depend on your workload and costs.

Step by step

How AI helps

Today: A practice with 12–20 staff and 80 or more clients, processing about 1,500 supplier bills and receipts a week, much of it still keyed by hand or by paid contract staff. Keying each bill — supplier, date, amount, GST and coding — takes about 4 minutes. Dext’s own estimate for manual entry is 3–4 minutes a document.

What AI does

  1. Clients email, upload or photograph bills into Dext (or Xero’s Documents inbox).
  2. Dext extracts supplier, date, amount, tax, currency and invoice number, and validates the ABN.
  3. Supplier rules fill in the default category, tax rate, payment method and due date for each supplier.
  4. Items from trusted suppliers auto-publish to the client’s ledger; new suppliers, suspicious items and anything held for approval wait in the inbox.

Your team still

  • Set up supplier rules carefully (Dext’s line items do not carry tax codes, so rules decide GST).
  • Review new suppliers, mixed-GST bills, credit notes and anything flagged.
  • Reconcile in the ledger as usual.

Tools: Dext, or Xero’s built-in capture. If most clients are on Xero, its built-in capture costs nothing extra; Dext adds MYOB support, line items and stronger rules. Start auto-publish with a few consistent suppliers, as Dext recommends.

Two ways to do it

AI automation or an AI agent?

Our view: A purpose-built capture tool such as Dext is more consistent at this volume. The agent suits smaller practices, or chasing clients for missing documents.

AI automation

Pros

  • Built for bills: supplier rules, ABN checks and automatic posting
  • Connects directly to Xero, MYOB and QuickBooks
  • The bigger saving of the two options

Cons

  • Per-client fees add up (about $1,050 a month at 50 clients)
  • GST is only as good as your supplier rules
  • Items posted by Dext cannot be unposted

AI agent

Pros

  • No per-client fees
  • Can also chase clients for missing paperwork

Cons

  • Reads bills less consistently than a purpose-built tool
  • Entering bills into Xero through a browser is untested
  • Client financial data is processed outside Australia
How an AI agent would do it
  1. The dot watches the bills inbox (Gmail can trigger it as each email arrives; Outlook is checked on a schedule).
  2. It reads each bill and records supplier, date, amount and GST in a review sheet, flagging anything unclear or duplicated.
  3. After approval, it enters the bill as a draft in Xero through its browser, where the site allows it.
  4. It drafts emails to clients about missing or unreadable documents.

Before you decide

If the saving is smaller

If AI saves 25% less time than we assume, AI automation pays for itself in about 5 months and saves about $69,150 a year. These figures value every hour saved at the hourly cost, because your team can put the time into other work, such as more clients or fewer extra hours.

What we check first

  • How bills are handled now, including any existing capture tool.
  • Client count by ledger (Xero, MYOB, QuickBooks).
  • What your team will do with the time saved, such as more client work or fewer extra hours.
  • GST coding rules for each client, checked before auto-publish is switched on.

Not included: Payments, bank-detail changes, BAS lodgement and tax advice.

A rough total is fine.

Wage plus on-costs like super and leave, often 20–30% more. Time saved is valued at this rate.
