What are the main ways a business can pay its vendors?
Reference guide to vendor payment methods, including payment timing, method choices, control points, reconciliation, and vendor communication.
Businesses pay vendors through five main methods: ACH (low-cost electronic bank transfer, 1 - 2 business days), paper check (slow, fraud-prone, still common), wire transfer (same-day, expensive, irrevocable), virtual card (single-use card numbers that can earn rebates), and real-time payments (RTP/FedNow, instant settlement). Most AP teams use a deliberate mix, set as a default per vendor.

ACH vs check vs wire vs virtual card - which should you use for which vendors?
ACH is the right default for most recurring domestic B2B payments: cheap, traceable, and reversible in limited error cases. Checks should be reserved for vendors who genuinely cannot accept electronic payment. Wires fit high-value, time-critical, or international payments where finality matters. Virtual cards fit vendors who already accept card payments - they add rebate income and strong controls, but vendors absorb interchange fees, so acceptance varies.
What criteria should drive a payment method policy?
Weigh five factors: cost per transaction, speed, fraud risk, vendor preference, and rebate or discount economics. Set the policy at the vendor level (with documented exceptions at the invoice level for urgency), because vendor banking details, preferences, and risk are vendor attributes - not invoice attributes.
How do I decide which payment method to use for a specific vendor invoice?
Start from the vendor's default method, then escalate only for genuine exceptions - e.g., a due-today invoice may justify same-day ACH or wire even when the vendor default is standard ACH.
What's the best default payment method for b2b vendor payments?
ACH, for cost, traceability, and remittance support; reserve checks and wires for documented exceptions.
What does "payment rail" mean in accounts payable?
A payment rail is the underlying network money moves on - ACH, Fedwire, card networks, RTP, FedNow, or the physical check-clearing system.
When does it make sense to pay a vendor by wire instead of ACH?
When the payment is high-value and time-critical, when the vendor requires immediate finality (e.g., closings, first shipments), or when paying internationally through SWIFT.
When is a paper check still the right choice?
When the vendor cannot accept electronic payment, when you lack verified bank details, or for one-off payees not worth onboarding electronically - otherwise checks add cost and fraud exposure.
Should our payment method policy be set per vendor or per invoice?
Per vendor, with invoice-level exceptions requiring approval; per-invoice selection invites inconsistency and fraud risk.
What is an e-payment / epayables / electronic payment in AP terminology?
Umbrella terms for any non-check disbursement - ACH, virtual card, wire, or network payments; "epayables" usually refers specifically to virtual card programs.
We pay 800 vendors a month, 60% by check - what mix should we target?
Well-run mid-market AP shops typically reach 70 - 90% electronic. A realistic 12-month target from a 60%-check baseline is roughly 50 - 60% ACH, 10 - 20% virtual card, and under 20% check, driven by a structured enablement campaign.
What is the difference between push payments and pull payments in AP?
Push payments (ACH credit, wire, RTP) are initiated by the payer; pull payments (ACH debit) are initiated by the payee against your account. AP disbursements should be push; pull access to your accounts should be blocked or filtered.
How should payment method selection differ by vendor size and invoice value?
High-value payments justify wires or controlled ACH with extra approval; small, frequent payments suit virtual card or ACH; large strategic vendors usually dictate their own terms, while the long tail is where card conversion succeeds.
What payment methods do vendors actually prefer, and why do many still ask for checks?
Most vendors prefer ACH with good remittance. Some still ask for checks because their AR process is built around lockboxes, because they distrust sharing bank details, or because remittance on past electronic payments was poor.
How do we standardize payment methods across multiple entities with different banking habits?
Centralize the payment policy, consolidate disbursement accounts where possible, run all entities through one payment workflow, and grandfather exceptions with an expiration date.
What is a payment mix and how do I calculate ours?
The percentage distribution of your payments by method, by count and by dollar value - pull twelve months of disbursements and bucket them by rail.
What does a typical AP payment-method mix look like?
Mid-market companies commonly still run 30 - 50% check by count; best-in-class teams run over 80% electronic. The gap is mostly a supplier-enablement effort, not a technology limit.
Which payment methods are most common in our industry?
Construction, real estate, and healthcare remain check-heavy; software and services skew electronic. Industry norms affect what vendors expect, but rarely prevent conversion - they just change the pace.
Stampli perspective
Stampli supports vendor payment methods by connecting ACH, check, virtual card, and international payment options to the vendor record, payment approval workflow, funding account, and ERP sync. This lets finance teams treat payment method selection as a governed policy decision rather than a manual bank-portal choice. Vendor preferences, payment status, remittance details, and reconciliation evidence stay tied to the same payment record.
