Accounts Payable Glossary: 25 Terms Every Accountant Should Know

Accounts payable (AP) is the lifeblood of every finance team but the terminology can get dense. From invoice automation to three-way matching, understanding key AP terms helps accountants, bookkeepers, and finance leaders manage payables with precision and confidence.

This glossary breaks down 25 essential accounts payable terms, written in clear, plain language and aligned with how modern AP automation platforms like MakersHub operate today.

Whether you’re training a new staff member, exploring automation, or just want a refresh, this is your go-to reference for mastering AP.

Accounts payable glossary

1. Accounts payable (AP)

The total amount a business owes to its vendors or suppliers for goods and services received but not yet paid for. AP sits as a liability on the balance sheet and represents short-term debt.

2. Accounts payable automation

The process of using software to manage invoice intake, approval routing, and payment execution automatically. MakersHub’s AI-driven automation eliminates manual data entry, saving finance teams hours each week.

3. Accounts payable workflow

The sequence of steps that an invoice follows from receipt to payment including data capture, coding, approvals, and reconciliation. Well-designed workflows ensure accuracy and prevent bottlenecks.

4. Accounts payable aging report

A report that categorizes outstanding payables based on how long they’ve been due, commonly shown in 30, 60, and 90-day intervals. It’s essential for managing cash flow and identifying overdue payments.

5. Approval workflow

A predefined process that determines which stakeholders must review or approve invoices before payment. MakersHub lets you configure approval rules by vendor, department, or project for total control.

6. Audit trail

A chronological record of every action taken in the AP process from who approved a bill to when a payment was sent. Automation tools automatically maintain this trail, ensuring compliance and transparency.

7. Bill capture

The process of collecting and digitizing bills from multiple sources (email, uploads, photos). With MakersHub, all bills flow into a single inbox where AI reads and structures them automatically.

8. Clean data problem

A common challenge in AP where invoice data is inconsistent, incomplete, or formatted differently across vendors. MakersHub solves this by extracting, labeling, and coding every line item accurately.

9. Duplicate invoice detection

A control mechanism that identifies and blocks duplicate invoices from being processed or paid twice: critical for fraud prevention and audit integrity.

10. Early payment discount

A financial incentive offered by vendors to encourage faster payment (for example, “2/10, net 30” means a 2% discount if paid within 10 days). Automation helps capture these savings consistently.

11. Electronic funds transfer (EFT)

The electronic movement of funds from one account to another, such as ACH payments. EFTs are faster, more traceable, and more secure than paper checks.

12. General ledger (GL) coding

Assigning each invoice or expense to the correct GL account, cost center, or project. MakersHub automates GL coding using AI trained on vendor and transaction patterns.

13. Invoice approval

The step where an invoice is reviewed and authorized for payment. In manual systems, this often requires multiple email threads; automation keeps it structured and traceable.

14. Invoice processing

The end-to-end handling of supplier invoices, including data entry, validation, approval, and payment. Automating this process reduces errors and accelerates cycle times.

15. Line-item extraction

The ability of an automation platform to read and structure data from each individual product or service line on an invoice not just the total amount. MakersHub’s WiseVision AI performs full line-level extraction for complete accuracy.

16. Matching (two-way and three-way)

Matching ensures that an invoice corresponds with the correct purchase order and receipt.

  • Two-way match: invoice vs. purchase order
  • Three-way match: invoice vs. purchase order vs. goods receipt
    Automation performs these matches instantly to prevent overpayments and fraud.

17. Multi-entity accounting

The ability to manage payables across multiple business entities or subsidiaries from a single platform. MakersHub’s workflows support entity-specific approvals and reporting.

18. OCR (optical character recognition)

Technology that converts printed or scanned text into digital data. While basic OCR can extract headers, advanced AI systems like MakersHub go further: interpreting the context and structure of invoices.

19. Payment authorization

The formal approval step before funds are released. Separating validation from payment authorization reduces errors and enhances internal controls.

20. Purchase order (PO)

A document issued by a buyer authorizing a vendor to supply goods or services. PO matching ensures that what’s billed aligns with what was ordered and received.

21. Reconciliation

The process of ensuring that payment records in the AP system match the transactions in the accounting ledger or bank account. Automation provides real-time reconciliation for complete accuracy.

22. Remittance advice

A communication sent to a vendor confirming that a payment has been made, detailing which invoices were paid and for how much. MakersHub automates these notifications without requiring vendor logins.

23. Spend visibility

The ability to see where money is going in real time across vendors, categories, and departments. Full visibility helps finance leaders make informed, proactive decisions.

24. Vendor management

The process of maintaining vendor information, payment terms, and communications. Centralized vendor data ensures accurate payments and smoother collaboration.

25. WiseVision AI

MakersHub’s proprietary AI technology for document processing. It combines computer vision, language models, and adaptive learning to extract, structure, and code invoices with unmatched accuracy.

Why this glossary matters

Understanding these core AP terms isn’t just academic: it’s how accounting professionals align accuracy, compliance, and efficiency.

When teams grasp the difference between basic OCR and AI-based extraction, or between invoice validation and payment authorization, they make better software decisions and operate with more control.

Finance leaders who use this glossary as a shared resource help their teams:

  • Communicate more clearly about processes
  • Reduce training time for new hires
  • Identify automation opportunities
  • Build a stronger foundation for audits and compliance
