MYOB + AI: Automate Bookkeeping, Payroll, and BAS Prep

To automate MYOB with AI, connect your MYOB Business account to Make.com using MYOB’s API, then build workflows that handle expense categorisation, bank reconciliation, payroll processing, BAS preparation, supplier payments, and cash flow reporting automatically. This eliminates hours of repetitive bookkeeping each week while reducing errors and improving financial visibility.

Why Australian Businesses Should Automate MYOB

MYOB remains one of Australia’s most popular accounting platforms, used by hundreds of thousands of small and medium businesses. It’s solid software, but let’s be honest—nobody starts a business because they love data entry. Manually categorising expenses, reconciling bank feeds, processing payroll, and preparing BAS statements eats up hours every week that could be spent on actual revenue-generating work.

The good news is that MYOB’s API has matured significantly, and when you connect it to AI-powered workflow automation, you can eliminate most of the manual grunt work. This isn’t about replacing your bookkeeper or accountant—it’s about freeing them to focus on advisory work rather than data entry.

Expense Categorisation With AI

One of the most tedious bookkeeping tasks is categorising expenses. Every bank transaction needs to be matched to the right account code, and when you’re doing this manually for hundreds of transactions per month, mistakes are inevitable.

AI-powered expense categorisation works by analysing the transaction description, amount, and your historical categorisation patterns. Here’s how to set it up with MYOB and Make.com:

The Workflow

Trigger: New bank feed transaction appears in MYOB.
AI Analysis: Make.com sends the transaction details to ChatGPT (or Claude) with your chart of accounts and categorisation rules.
Categorisation: The AI suggests the correct account code based on the merchant name, amount, and description.
Confidence Check: If the AI is 90%+ confident, it auto-categorises. If below 90%, it flags the transaction for manual review.
Learning: Over time, the AI learns from your corrections and becomes more accurate.

The result is that 70–85% of your transactions are auto-categorised correctly, and the remaining 15–30% are flagged for quick human review. What used to take 3 hours per week now takes 20 minutes.

Automated Bank Reconciliation

Bank reconciliation in MYOB can be partially automated by combining the bank feed with AI matching logic. The AI compares incoming bank transactions against outstanding invoices and expected payments, then suggests matches. For recurring expenses (rent, subscriptions, utilities), the system learns the pattern and auto-reconciles after the first few months.

The key is building rules that handle your specific business patterns. A tradesman might have regular Bunnings purchases that always go to “Materials.” A professional services firm might have monthly SaaS subscriptions that always go to “Software Expenses.” The AI identifies these patterns and creates rules automatically.

Payroll Automation

MYOB’s payroll module handles the calculations, but there’s still manual work involved in collecting timesheets, checking leave balances, and processing each pay run. AI automation can streamline this significantly:

Timesheet collection: Automatically pull timesheet data from your rostering system (Deputy, Tanda, or even a shared Google Sheet) and feed it into MYOB.
Leave management: When staff submit leave requests via email or a form, the automation checks their balance in MYOB, approves or flags the request, and updates the roster.
Pay run preparation: The automation prepares the pay run data, including any allowances, deductions, or variations, and presents it for a single-click approval.
Payslip distribution: After processing, payslips are automatically emailed to each employee from MYOB.
Super lodgement reminders: Automated reminders before super guarantee deadlines, with the data pre-populated for quick lodgement.

For businesses with 5–50 employees, this reduces payroll processing from a half-day task to 15 minutes of review and approval.

BAS Preparation Automation

BAS preparation is one of those quarterly tasks that causes anxiety for many business owners. Getting the GST figures wrong can mean ATO penalties, and manually calculating everything is error-prone. Here’s how AI automation helps:

Automated BAS Prep Workflow

Pre-BAS review: Two weeks before the BAS deadline, the automation runs a health check on your MYOB data—looking for uncategorised transactions, missing GST codes, and unreconciled items.
Alert notifications: You (or your bookkeeper) receive a summary of items that need attention before the BAS can be prepared.
GST calculation verification: The AI cross-references your MYOB GST report against your bank statements to catch discrepancies.
Draft BAS generation: Once the data is clean, the automation generates a draft BAS summary for review.
Lodgement reminder: Automated reminders at 14 days, 7 days, and 2 days before the deadline.

If you’re already using Xero with AI automation, the principles are identical—only the API connections differ. Many of the same Make.com scenarios work with both platforms.

Supplier Payment Scheduling

Cash flow management is critical for Australian SMEs, and supplier payment timing is a key lever. AI automation can help you optimise when you pay suppliers:

Due date tracking: The automation monitors all outstanding supplier invoices in MYOB and creates a payment schedule.
Early payment discount detection: If a supplier offers a discount for early payment (e.g., 2% for payment within 7 days), the AI flags these opportunities and calculates whether the discount is worth taking based on your current cash position.
Payment batch preparation: On your chosen payment day, the automation prepares a batch of supplier payments for single-click approval.
Cash flow forecasting: By analysing payment patterns, receivables, and upcoming obligations, the AI provides a rolling 30/60/90-day cash flow forecast.

Cash Flow Reporting

Most business owners check their bank balance and hope for the best. AI-powered cash flow reporting gives you actual visibility:

Daily cash position: An automated morning email or Slack message showing your current cash position across all accounts.
Weekly P&L snapshot: A simple profit and loss summary pulled from MYOB and formatted for quick reading.
Monthly dashboard: A Google Sheet or dashboard that auto-updates with key financial metrics from MYOB.
Anomaly alerts: The AI monitors for unusual transactions (unexpectedly large expenses, duplicate payments, missing expected income) and alerts you immediately.

Setting Up MYOB + Make.com Integration

The technical setup involves connecting MYOB’s API to Make.com. Here’s the high-level process:

MYOB API access: Register for MYOB API access through the MYOB Developer portal. You’ll receive API credentials (Client ID and Client Secret).
Make.com connection: In Make.com, use the HTTP module to connect to MYOB’s API endpoints. You’ll authenticate using OAuth 2.0.
Build scenarios: Create individual scenarios for each workflow (expense categorisation, payroll prep, BAS checks, etc.).
Test thoroughly: Run each scenario with test data before going live. Pay particular attention to GST handling and account code mapping.
Monitor and refine: Watch the automations for the first month and adjust rules based on accuracy.

For professional services firms, these automations are particularly valuable because they free up billable hours that were previously consumed by internal admin work.

Common MYOB Automation Pitfalls to Avoid

A few things to watch out for when automating MYOB workflows:

GST handling: Always verify that automated categorisations apply the correct GST code. A mistake here flows through to your BAS.
API rate limits: MYOB’s API has rate limits. Design your automations to batch requests rather than making individual calls for every transaction.
Multi-currency: If you deal with foreign suppliers, ensure your automation handles currency conversion correctly.
Year-end processes: Some automations need to be paused or adjusted during financial year-end processes. Build in awareness of your financial year dates.

Frequently Asked Questions

Does this work with MYOB Business or just MYOB AccountRight?

These automations work with both MYOB Business (the cloud version) and MYOB AccountRight Live. The API endpoints differ slightly, but Make.com can connect to both. MYOB Business is easier to integrate because it’s fully cloud-based.

How accurate is AI expense categorisation?

In our experience, AI categorisation achieves 75–85% accuracy out of the box, improving to 90%+ within 2–3 months as it learns your specific patterns. The confidence threshold (we recommend 90%) ensures low-confidence categorisations are flagged for human review.

Will my accountant be okay with automated bookkeeping?

Most accountants welcome automation because it means cleaner data when they receive your file. The automation doesn’t replace accountant oversight—it eliminates the tedious data entry so your accountant can focus on strategic advice. We recommend involving your accountant in the setup to ensure account codes and GST rules are mapped correctly.

How much does MYOB API access cost?

MYOB API access is included with your MYOB subscription at no additional cost. You’ll need a Make.com subscription (from $9/month for basic plans) and potentially a ChatGPT API key (pay-per-use, typically $5–20/month for a small business).

Can I automate MYOB invoicing as well?

Absolutely. You can create automations that generate and send invoices based on completed jobs, time entries, or scheduled billing. This is particularly useful for businesses that invoice regularly for recurring services.

What happens if the automation makes a mistake?

Every automated action is logged, so mistakes are easy to trace and correct. The confidence threshold system means uncertain categorisations are always flagged for review. For critical processes like BAS preparation, the automation generates a draft for human review rather than lodging directly.
