How this usually works
When you ask how to manage accounts payable, start with the outcome you want: predictable cash requirements, zero late fees, accurate GST credits, fewer supplier queries, and clean month-end reporting.
Build a simple workflow that everyone follows:
- Intake: all bills go to a single inbox or eInvoicing channel connected to your software.
- Validation: check ABN, GST, dates, amounts, PO/receipt match and duplicate detection.
- Coding: choose the right expense account, project/job, tax code and tracking categories.
- Approval: route to budget owners with thresholds and an approval matrix.
- Payment: run weekly or fortnightly batches with dual authorisation and clear cut-offs.
- Reconciliation: match payments, mark bills as paid and investigate any exceptions.
Australian context to keep in view
- GST credits require a valid tax invoice. Confirm the supplier’s ABN and GST registration, and apply the correct GST code (e.g. GST on expenses, GST free, input taxed).
- No ABN? You may need to withhold at the top marginal rate unless an exemption applies.
- Use eInvoicing (Peppol) or “email to bills” to reduce manual entry and duplicates in Xero, MYOB or QuickBooks.
- ABA files and bank user roles help enforce separation of duties and reduce payment fraud.
- Larger entities should consider supplier payment policies and the Payment Times Reporting Scheme obligations.
Step-by-step: how to manage accounts payable
1) Supplier onboarding
Collect ABN, GST status, bank details, contacts and terms. Verify ABN via ABN Lookup, set default coding and attach contracts/PO terms.
2) Capture and check
Use eInvoicing/OCR to ingest bills. Validate vendor, date, due date, line items, PO/GRN match and duplicates. Flag exceptions for review.
3) Code and approve
Apply correct GL, project/tracking and GST code. Route approvals by amount/category with an audit trail (e.g. ApprovalMax, Lightyear).
4) Payment runs
Schedule weekly/fortnightly runs. Export ABA, require two approvers, prioritise early‑payment discounts, and respect cash flow forecasts.
5) Reconcile and close
Reconcile bank lines daily. Month‑end: supplier statement recs, accruals for unbilled costs, review aged payables and DPO trends.
6) Improve continuously
Measure invoice cycle time, first‑pass match rate, exceptions and duplicate rate. Tweak terms, processes and automation rules.
What to compare before you commit
Scope
Confirm the provider will handle intake, coding, approvals, supplier queries, payment files, GST review and month‑end reconciliations.
Software fit
Look for proven workflows in Xero/MYOB/QBO plus tools like Dext, Hubdoc, ApprovalMax or Lightyear, and clear documentation of rules.
Controls and security
Ask about segregation of duties, dual approvals, user roles, bank access, audit logs and how vendor changes are authorised.
Commercial fit
Check turnaround SLAs, billing model, peak-period support, and whether you need compliance only or broader advisory/cash flow help.
Best next steps
Decide if you’re improving an existing workflow or building from scratch. List your top pain points (late fees, duplicate bills, messy GST, supplier noise) and prioritise quick wins.
- Pick a single intake channel and switch on automation (email to bills, eInvoicing, rules).
- Document your approval matrix and payment calendar and share it with budget owners.
- Add AP metrics to your month‑end pack: aged payables, DPO, overdue %, exceptions.
- Schedule a BAS review of GST coding before each lodgement.
If you want hands‑on support, compare bookkeeping services, BAS agent services for GST/BAS accuracy, or broader accounting services if you need cash flow and supplier strategy input.
Frequently asked questions
What is accounts payable?
Accounts payable is the end‑to‑end process of receiving, checking, coding, approving and paying supplier invoices, then reconciling them in your accounting system. Strong AP improves cash flow control, GST accuracy and supplier relationships.
How do I manage accounts payable step-by-step?
Onboard suppliers, capture bills centrally, verify details and GST, code to the right account, approve to policy, run scheduled payment batches with dual authorisation, reconcile, and review supplier statements and aged payables each month.
How do I handle GST on supplier bills?
Only claim GST credits when you hold a valid tax invoice. Confirm the supplier’s ABN and GST status, apply the correct tax code, and review GST before BAS lodgement. If a supplier doesn’t quote an ABN, no‑ABN withholding rules may apply.
Which software is best for AP in Australia?
Xero, MYOB and QuickBooks all handle AP well. Add tools such as Dext/Hubdoc for capture, ApprovalMax/Lightyear for approvals, and use ABA files with dual bank authorisation for secure payments. Choose based on volume, approval complexity and integration needs.
