B2B Payment Processing for Wholesale: Net Terms, ACH, and Credit Card Options

How B2B Payment Processing Differs From Retail

When a consumer buys something online, they enter a card number and the transaction clears in seconds. That model doesn’t work in wholesale.

A buyer ordering $40,000 of product from a distributor isn’t putting that on a Visa. They’re submitting a purchase order, expecting an invoice with their contracted net terms, and processing payment through their accounts payable department on the due date. The entire workflow — PO issuance, invoicing, payment, and reconciliation — runs through systems that have nothing to do with a card swipe.

This distinction matters when choosing how to handle payments on a B2B ordering portal. Retail payment infrastructure handles one part of the equation (credit card transactions). B2B payment processing handles the full cycle.

Net Terms: The Default Payment Method in Wholesale

Net terms are the expectation in B2B wholesale, not an exception. When a buyer has been purchasing from you on net 30 for three years, requiring them to pay by credit card online will push them back to phone ordering.

Net 30, net 60, net 90 — these numbers represent days from invoice date to payment due. Net 30 is standard for most accounts. Net 60 and net 90 are reserved for larger buyers with more leverage or higher seasonal order volumes.

Managing net terms online requires:

• A payment method option at checkout labeled “Net 30” or “Net 60” (not just “credit card” or “ACH”)
• Per-account credit limits that the platform enforces automatically
• Invoice generation with the due date calculated at order time
• An aging report showing which invoices are current, upcoming, or overdue
• An account hold mechanism for buyers who exceed their credit limit or are past due

Without these, net terms exist on paper but create manual work every time a buyer places an order.

ACH Transfers: The Standard for B2B Payment Settlement

ACH is how most B2B payments actually settle. The buyer’s accounts payable department initiates an ACH transfer (or you pull it via direct debit) when the invoice is due.

The economics favor ACH at wholesale volumes. Credit card interchange runs 1.5-3% of transaction value. ACH costs $0.20-$1.50 per transaction regardless of amount. On a $25,000 invoice, the difference is $625+ in processing fees versus under $2 for ACH.

For your ordering portal, ACH works as both:

• Invoice payment method: buyers pay due invoices by ACH from their bank account
• Order payment method: for accounts that don’t have established credit, ACH on-account functions like prepay with bank transfer settlement

ACH settlement takes 1-3 business days. For most wholesale invoices with 30-day terms, this delay is irrelevant.

Wire Transfers for Large and International Orders

Wire transfers are ACH at higher stakes — same bank-to-bank mechanic, faster settlement (same day or next day), and typically used for orders above $50,000-$100,000 or for international buyers where ACH doesn’t apply.

Wires carry higher fees ($15-$35 per transaction at most banks) but the speed and finality make them worth it for large orders. Unlike ACH, wires are irrevocable once sent, which reduces fraud risk for high-value transactions.

If you sell internationally, wire via SWIFT is the standard. SWIFT codes and IBAN numbers are the identifiers that route international payments, similar to routing and account numbers for domestic ACH.

Credit Card Processing: When It Makes Sense (and When It Doesn’t)

Credit cards are appropriate for B2B in a narrow set of cases:

• New accounts before they establish a payment history — require credit card or prepay until they’ve completed 2-3 orders cleanly
• Small-value orders under $2,000-$3,000 where interchange is a manageable cost
• Ad hoc buyers who aren’t regular wholesale accounts
• International buyers where wire is too cumbersome for smaller orders

For established accounts ordering at volume, credit cards are the wrong default. A buyer ordering $30,000 of product monthly at 2.5% interchange is paying $750/month extra — or passing that cost to you if you absorb fees.

Some B2B buyers also have corporate card programs that work well for smaller purchases but hit credit limits or require per-transaction approval for large orders.

Payment Automation: Invoicing, Aging, and Collections

Manual AR is the bottleneck in most wholesale operations that move online. The goal is to automate every repeatable step:

Invoice generation: When an order is confirmed, the platform generates an invoice with the PO reference, line items, tax, and due date. No manual creation.

Aging reports: Updated daily, showing every open invoice sorted by days outstanding. Your AR team works from this report to prioritize collections — not a spreadsheet they maintain by hand.

Automated payment reminders: A reminder sequence triggered by invoice due dates:

• 7 days before due: advance notice
• 3 days before due: follow-up
• Due date: payment confirmation request
• 7 days past due: overdue notice
• 14 days past due: account hold warning

Account holds: The most effective collection tool in B2B. When a buyer can’t place new orders until their overdue balance clears, late payments resolve quickly. Configure your portal to enforce this automatically.

Reconciliation: When a payment arrives, it should match against the open invoice automatically. Unmatched payments require manual review but should be rare if buyers reference invoice numbers in their payment details.

How OrderDock Handles Payment Workflows

We built OrderDock to handle the full B2B payment cycle starting at $20/month — not bolt net terms onto a retail checkout.

Each buyer account has configurable payment terms (net 30, net 60, net 90, or prepay), a credit limit, and a payment method setting. When a buyer submits an order on terms, the platform generates the invoice, logs the receivable, and starts the reminder sequence automatically.

Accounting integrations sync invoices and payments to QuickBooks or your ERP so your accounting team sees real-time receivables without manually exporting data from the portal.
