Accounts Payable Automation
The use of software to capture, code, validate, approve, and post supplier invoices without manual data entry. Accounts payable automation covers the full workflow from invoice receipt through to the accounting ledger, replacing manual steps with rules, AI, and structured workflows.
AP Controls Stack
A five-layer framework for accounts payable automation developed by Pulsify. The five layers are: Capture, Coding, Validation, Approval, and Ledger. Each layer must operate correctly and in sequence for AP to be accurate, efficient, and audit-ready. Most AP tools cover only one or two layers; gaps between layers are where errors accumulate.
Automated Line-Item Coding
The automatic assignment of account codes to individual line items on a supplier invoice, using AI trained on the business's historical coding patterns. Line-item coding differs from invoice-level coding: a single invoice (such as a freight forwarder bill) may require multiple account codes across different line items, each with different GST treatment.
Confidence Scoring
A reliability indicator assigned by AP automation software to each processed invoice. High-confidence invoices - those that match historical supplier patterns, pass validation checks, and follow known coding rules - proceed with minimal human review. Low-confidence invoices - those that deviate from norms or contain unfamiliar line items - are routed to a human reviewer. Confidence scoring reduces the volume of invoices requiring manual attention while ensuring genuinely unusual invoices receive it.
Deferred GST (Import GST)
GST assessed by the Australian Border Force on goods imported into Australia. Unlike domestic GST, which is charged by a supplier on their invoice, import GST is paid at the border and claimed as an input tax credit on the BAS via a separate mechanism. In Xero, it uses the 'GST on Imports' tax rate; in MYOB, it requires a specific deferred GST tax code mapped to the G20 BAS label. Incorrectly coding import GST as standard supplier GST produces false input tax credit claims.
Duplicate Invoice Detection
An automated check that identifies invoices that have previously been processed, preventing double payment. Effective duplicate detection goes beyond matching invoice numbers - it also flags invoices with identical amounts from the same supplier within a defined time window, and invoices that share line-item content with a prior invoice even under a different reference number.
Exception Handling
The process of reviewing and resolving invoices that fail automated processing checks. Exceptions include invoices with amounts outside the normal range for a supplier, missing PO references, GST inconsistencies, unrecognised line items, or suspected duplicates. Good exception handling routes only genuinely unusual invoices to human reviewers, rather than requiring manual review of all invoices.
Invoice Processing Automation
The automated intake, reading, and extraction of supplier invoice data from documents - PDFs, emails, scanned images, and eInvoices. Invoice processing automation captures header data (supplier name, date, invoice number, total) and line-item data (description, quantity, unit price, GST amount) using OCR and AI. It is the first layer of the AP Controls Stack and is a prerequisite for automated coding, validation, and approval.
Landed Cost
The total cost of acquiring imported goods, including the purchase price, international freight, insurance, customs duty, and any other charges incurred to bring the goods to their destination. Correct landed cost calculation requires that each component of a freight forwarder invoice is coded to the appropriate account. Freight forwarder invoices that are coded to a single 'freight expense' account understate the true cost of inventory.
Multi-Entity AP
Accounts payable operations that span more than one legal entity, trading name, or subsidiary within a business group. Multi-entity AP requires that invoices are posted to the correct entity, that intercompany transactions are handled correctly, and that approval rules reflect the authority structure of each entity independently. Without multi-entity support, finance teams managing several entities manually recreate the same AP process for each one.
PO Matching (Purchase Order Matching)
The process of comparing a supplier invoice against an approved purchase order to verify that the goods or services were ordered before payment is approved. Two-way matching compares the invoice to the PO. Three-way matching also compares the invoice to a goods receipt note (GRN), confirming delivery. PO matching catches invoices for goods never ordered, at prices different from what was agreed, or from suppliers not on the approved vendor list.
Reversibility Test
A framework for deciding which AP decisions are safe to automate and which require human review. Reversible decisions - those that can be corrected after the fact without material cost - are candidates for full automation. Irreversible decisions - those that trigger financial transactions, change supplier bank details, or create obligations that are difficult to unwind - require a human checkpoint regardless of automation maturity. The Reversibility Test is described in detail in Pulsify's post on what gets automated in Australian AP in 2026.
Three-Way Matching
An accounts payable control that compares a supplier invoice against both the original purchase order and the goods receipt note (GRN) before approving payment. Three-way matching confirms that goods were ordered (PO), delivered (GRN), and invoiced at the agreed amount. It is the most rigorous form of PO matching and is standard practice for high-value purchases or industries where delivery confirmation is critical, such as construction and manufacturing.
Vendor Bank Detail Validation
A check that flags changes to a supplier's bank account details before a payment is processed. Payment redirection fraud - where an attacker intercepts communication to substitute fraudulent bank details - cost Australian businesses AU$152.6 million in 2024 (ACCC). Vendor bank detail validation surfaces new or changed bank account information for manual review before payment, preventing unauthorised fund transfers to fraudulent accounts.
