MYOB Acumatica Accounts Payable in Australia: Vendor Bills, EFT Payments and BAS-Ready Coding

How the AP Module Works in MYOB Acumatica

MYOB Acumatica’s Accounts Payable module handles the full vendor-to-payment cycle: purchase orders, vendor bills, three-way matching, approval workflows, batch EFT payments, and GST tax coding that flows directly into your BAS. Everything runs in the same database as your general ledger — there is no export step between payables and accounting.

For an overview of the platform and what implementation involves, see MYOB Acumatica for Australian businesses.

Entering Vendor Bills

Bills are created in Accounts Payable → Bills and Adjustments. You can enter them manually, link them from a purchase order, or use the document capture feature to extract header fields from a scanned or emailed PDF.

Each line carries a GL account, a GST tax category, and optionally a project and task code. If you run MYOB Acumatica project accounting, costs flow to the project register automatically on entry — the committed cost register updates before the bill is even approved.

For businesses using the purchasing module, bills linked to a purchase receipt automatically pull the PO lines, quantities received, and agreed prices. The three-way match — PO quantity, received quantity, billed quantity — runs on confirmation. Variances outside your configured tolerance are held for review rather than posting automatically.

GST Tax Codes for BAS

MYOB Acumatica uses tax categories to classify each AP transaction for BAS reporting. The standard Australian categories map to their BAS boxes:

Tax category	Purpose
G10	Capital acquisitions with full input tax credit
G11	Non-capital acquisitions with full input tax credit
G13	Acquisitions for making input-taxed supplies
G15	Imported services (reverse charge)
FRE	GST-free acquisitions
NTR	Not reportable / out of scope

A default tax category set on each vendor record pre-fills when you raise a bill. Getting this right at the vendor level is the fastest way to reduce BAS misclassification — miscoded lines produce incorrect totals in G10 and G11 and require manual correction before lodgement.

Some Australian industries use recipient-created tax invoices (RCTIs) — agricultural produce, scrap metal, insurance settlements — where the buyer creates the tax invoice on behalf of the supplier. MYOB Acumatica supports RCTI workflows: you raise the vendor document, the system generates the tax invoice number, and the supplier receives a remittance rather than raising their own invoice.

ABA Batch Payments

MYOB Acumatica generates ABA-format batch payment files for upload to Australian business banking portals. The payment run process:

1. Build a payment batch — filter by due date, vendor, currency, or bank account
2. Apply early-payment discounts where configured on vendor records
3. Generate the ABA file with BSB, account number, payment reference, and amount per vendor
4. Upload to your bank portal (CommBiz, NAB Connect, ANZ Transactive, Westpac Corporate Online)
5. Return the bank statement line in MYOB Acumatica’s cash management module — the batch clears the AP ledger automatically

Foreign currency bills are paid from a matching currency bank account. The exchange gain or loss posts automatically at the rate on the payment date.

For wholesale and distribution businesses, MYOB Acumatica FastStart Wholesale Distribution includes a pre-configured AP and purchasing workflow as part of its 12-week implementation scope.

Bill Approval Workflows

MYOB Acumatica’s approval framework supports multi-level bill approval before posting or payment. Approval maps are configured per company, document type, and amount threshold — for example, under $10,000 requires one finance approver, over $50,000 requires CFO sign-off.

Approvers receive an in-system notification and optionally an email, review the bill alongside its attached PDF, and approve or reject with a reason inside the platform. Nothing in the workflow happens outside the ERP.

Landed Costs and Importer Workflows

For importers, vendor bills for freight, customs duty, and insurance can be allocated to the inventory lines they relate to using MYOB Acumatica’s landed cost module. The cost flows directly to inventory valuation rather than sitting as a separate GL line that never hits cost of goods sold — important for accurate gross margin and FIFO or AVCO costing.

The full multi-currency and landed cost workflow for importers is covered in our guide to MYOB Acumatica for importers and exporters in Australia.

Subcontractor Claims in Construction

For construction businesses, subcontractor progress claims are entered as vendor bills against the relevant project and job. Retention is withheld automatically if configured, and the retention payable clears when you release the hold at practical completion. MYOB Acumatica job costing tracks committed costs against each job in real time across the project register, so subcontractor exposure is visible before any invoice arrives.

AP Aging and Reporting

The AP Aging Summary shows outstanding balances by vendor and aging bucket — current, 30 days, 60 days, 90+ days — calculated against each bill’s due date. Generic Inquiries (MYOB Acumatica’s configurable report builder) let you filter and pivot AP data without a separate BI tool: bills on hold, unapproved bills by approver, payment history by supplier, due amounts by currency.

For cash flow visibility, AP outflow projections can be overlaid with AR inflows in the treasury module — useful for weekly or 13-week rolling cash forecasts.
