Accounts Payable (AP)
Money you owe suppliers for goods or services already received.
Definition
Accounts payable (AP) is the mirror image of AR: money you owe suppliers for invoices received but not yet paid. AP is a current liability. Smart AP management is about timing: pay on time to preserve relationships and avoid late fees, but not earlier than needed. Stretching payables (paying at the last allowed day) is a free source of working capital. Days Payable Outstanding (DPO) measures how long you take to pay; for most service businesses 30-45 days is the working range.
Strategic versus tactical AP management
Tactical AP management is paying every invoice on the latest allowed day to maximize float. Strategic AP management treats every vendor relationship as a negotiation. With critical vendors (a sole-source supplier, an irreplaceable contractor), pay early or on time to preserve goodwill. With commodity vendors (office supplies, SaaS), stretch to the edge of stated terms. With vendors offering early-pay discounts, do the math: 2/10 net 30 yields effective annual return of about 36 percent on the cash deployed, which beats almost any other use of working capital. Use AP automation tools (Bill.com, Ramp, Brex) to schedule payments precisely on the due date rather than days early.
Negotiating better payment terms
US small businesses systematically under-negotiate vendor terms. Standard ask: net 30. Realistic ask after building relationship: net 45 or net 60. With high purchase volume, ask for net 60 or net 90. Vendors are often willing because losing your account costs them more than carrying you for 30 extra days. Frame the ask as: 'We want to grow our spend with you. Can we move to net 60 terms?' Track DPO (Days Payable Outstanding) - extending DPO from 30 to 45 days on 1M of annual COGS frees up roughly 41K of working capital permanently.
AP automation and the close process
Modern US AP stacks use Bill.com, Ramp, Brex, or Stampli to capture invoices via email, OCR-extract data, route for approval, schedule payment via ACH, and sync to QuickBooks or NetSuite. The benefits: faster close (5 to 7 days instead of 15 to 20), fewer late payments, automated 1099 generation for contractors, and clean audit trail. Cost is typically 50 to 500 per month per user. For a business with 20+ vendor invoices per month, payback is usually under 6 months in saved bookkeeper time.
When to pay early intentionally
Pay early when: vendor offers an early-pay discount with effective return above your cost of capital (usually yes); vendor is critical and stressed and your timeliness builds long-term reciprocity; you have excess cash beyond reserves and yield on T-bills is below the implied vendor relationship return. Otherwise, never pay early. Cash on your balance sheet has option value - it lets you handle surprises, fund growth, or earn 4 to 5 percent in money market funds in the current US rate environment.
FAQ
What is a healthy DPO for a US small business?
Service businesses typically run 30 to 45 days DPO. Product businesses with supplier relationships can push to 45 to 75 days. Retail and e-commerce often run 60 to 90 days because suppliers price it in. The metric only makes sense relative to peers in your sector; compare to industry benchmarks (IBISWorld, RMA) rather than absolute. Rising DPO is good if it reflects negotiation power; bad if it reflects inability to pay.
Should I use a business credit card to extend AP?
Yes, intentionally. US business credit cards (Amex Business Platinum, Chase Ink, Capital One Spark) offer 25 to 55 days of free float plus cashback or points worth 1 to 5 percent on spend. Paying vendors via card effectively extends DPO by another billing cycle. The catch: many vendors charge 2 to 3 percent surcharge to accept cards, which usually wipes out the benefit. Use cards aggressively for SaaS, advertising, and travel; pay larger vendor invoices by ACH.
Does paying vendors late hurt my business credit?
Yes. US business credit scores (Dun & Bradstreet PAYDEX, Experian Intelliscore) are heavily influenced by trade payment history. Paying on time or early raises scores; paying late drops them. Banks and SBA lenders check these scores when evaluating credit applications. A pattern of 30+ day late payments can disqualify you from preferred terms with new suppliers and limit access to bank credit. The cost of preserving business credit usually outweighs the cash benefit of stretching specific invoices.
What is the difference between AP and accrued expenses?
AP is for invoiced obligations: you have received the invoice, it sits in your AP system, payment is scheduled. Accrued expenses are obligations incurred but not yet invoiced: wages earned but not yet paid, utilities used but not yet billed, taxes owed at month-end. Both are current liabilities on the balance sheet. Cleanly separating them matters for accurate management reporting and audit-readiness. Most accounting software handles the distinction automatically if vendor invoices are entered as bills rather than direct payments.
Should I pay 1099 contractors through AP or payroll?
1099 contractors are paid through AP, not payroll. Payroll is for W-2 employees with tax withholding. 1099 contractors invoice you (or you generate a vendor bill), you pay them via ACH or check, and at year-end you file 1099-NEC forms reporting total payments above 600. Tools like Gusto, QuickBooks Payroll, and Bill.com handle 1099 generation automatically. Misclassifying employees as 1099 contractors triggers IRS penalties; consult a CPA when boundaries are unclear.
In your business
- →Pay on time, not early - cash in your account is more valuable than supplier goodwill from paying 10 days early
- →Negotiate longer terms with major suppliers as the business grows
- →Never stretch payables with critical suppliers - the relationship cost is higher than the cash benefit
