The good news?

The best AP automation software not only speeds up your payments, but can also transform how your business controls cash flow and gains real financial visibility.

Let's take a look at the best accounts payable automation software, compare their strengths, key features, and who they’re best suited for—but, first:

What is accounts payable?

Accounts payable (AP) refers to the money a company owes to its suppliers or vendors for goods and services that have been received but not yet paid for. It's a liability on the company's balance sheet, representing an obligation to pay off short-term debts to its creditors.

In simpler terms, it's like a company's "to-do list" of payments it needs to make to others. Managing accounts payable efficiently is crucial for maintaining good relationships with suppliers and ensuring the company's cash flow remains healthy.

Accounts Payable examples

• Supplier invoices: Things like raw materials, office supplies, equipment
• Utilities: Include electricity, water, internet
• Rent & leases: Office, warehouse, equipment, vehicles
• Services & contractors: Payables related to consultants, legal, marketing, IT support
• Subscriptions: Like software, publications, recurring services
• Taxes: Sales tax, property tax, payroll tax
• Insurance premiums: Business, liability, employee benefits
• Freight & shipping: Logistics and transportation costs
• Licensing & permits: Business licenses, certifications
• Employee reimbursements: Travel, office supplies
• Maintenance & repairs: Facility, equipment, IT

The Accounts Payable (AP) process

1. Purchase Order (PO) creation & approval: Buyer submits a PO with details, which is reviewed and approved before sending to the vendor.
2. Delivery of goods/services: Vendor confirms PO, delivers goods/services, and the receiving department verifies delivery.
3. Invoice receipt & verification: Vendor submits an invoice; AP logs it and verifies accuracy through:
   • Two-Way Match (PO + Invoice) for services
   • Three-Way Match (PO + Invoice + Delivery Receipt) for goods
4. Invoice coding & classification: AP assigns General Ledger (GL) codes for proper expense tracking.
5. Approval & sign-off: Invoice is routed for approval to ensure accuracy and budget compliance.
6. Payment Scheduling & Execution: Payments are scheduled based on due dates and cash flow using methods like ACH, checks, wire transfers, or digital payments.
7. Payment Processing & Recording – Payment is executed, reducing the AP balance, and recorded in the general ledger.
8. Reconciliation & Reporting: AP reconciles payments with bank/vendor statements and tracks unpaid invoices through AP Aging Reports.
9. Compliance & Auditing: Internal audits ensure policy compliance, fraud prevention, and process optimization (e.g., dual approvals for high-value transactions).

Challenges in managing Accounts Payable

• Manual data entry errors: Human errors in entering invoice details causes discrepancies, overpayments and reconciliation issues.
• Invoice matching issues: Difficulty in 2-way or 3-way matching results in delayed payments, supplier disputes, accounting errors.
• Approval bottlenecks & delays: Slow manual approval processes cause late payments, missed early payment discounts, late payments and strained supplier relationships.
• Fraud risk: Fake invoices, duplicate payments and internal fraud can cause financial losses and reputational damage.
• Lack of visibility and tracking: Manual processes make it hard to track the status of invoices and payments, leading to poor cash flow management and delayed payments.
• High processing costs: Manual processing requires more staff time, leading to increased labor costs and inefficiencies.
• Compliance Issues: Difficulty tracking tax laws, VAT, and audit trails increase the risk of penalties, tax errors and audit failures.
• Duplicate or over payments: Paying the same invoice multiple times results in cash leakage and time-consuming recovery efforts.
• Limited cash flow control: Poor visibility into upcoming liabilities causes cash shortages and missed strategic payments.
• Lack of integration with other systems: AP isn't connected to ERP, procurement, or accounting.
