If you’re in the AI/SaaS space or a digital-product company selling to other businesses, understanding how B2B online payments work is key to keeping cash flowing.
B2B payments have shifted rapidly — more vendors, more tools, and more chances for invoices and receipts to fall out of step.
A B2B payment gateway, unlike consumer-focused systems built for speed and one-click checkouts, B2B platforms are built to handle large-value transfers, payment terms, multi-step approvals, and the nuance of enterprise billing.
Let’s break down the typical process step by step: from the moment a business hits “Buy” to when the seller finally receives the funds.
What are B2B Payment Gateways
A B2B payment gateway is a secure online platform that lets one business collect payments from another. It’s basically a secure gateway that transfers the buyer’s payment to the seller’s bank account.
B2B gateways are built for business needs: they handle high-volume transactions, integrate with invoicing or ERP systems, and support features like recurring billing or large-sum transfers.
Using a B2B gateway means payments are encrypted and processed automatically, reducing errors and speeding up billing between companies.
Types of B2B Payment Gateways
Different businesses may use different gateway setups. Integrated gateways plug straight into a company’s existing systems (ERP/accounting) for automatic reconciliation.
Standalone gateways operate independently, requiring minimal changes to internal software, useful if you’re not ready for a full system overhaul.
There are also mobile gateways for on-the-go payments via smartphones or tablets, handy for field sales.
cross-border gateways that handle international B2B transactions across currencies and compliance zones. The right choice depends on your scale and where your buyers are located.
How B2B Payments Actually Work: Step-by-Step
Here’s a simplified flow of a B2B online transaction:
Checkout Page:
The buyer enters necessary details like company info, billing address to calculate taxes, and any discount codes.
The system computes taxes and applies promotions, then shows the final invoice amount in the buyer’s preferred currency.
It also lists all valid payment methods for that country or currency like credit cards, ACH/bank transfer, digital wallets, etc., so the buyer can choose how to pay.
Payment Orchestrator:
The orchestrator presents all available payment options to the buyer and, once a method is selected, routes the transaction to the appropriate processor or gateway.
Think of it as a traffic controller: it manages multiple payment channels like cards, bank transfers, wallets and sends the payment to the best one.
A payment orchestrator is essentially “a solution that brings together a multitude of services,” helping businesses handle multiple payment methods and currencies more efficiently.
Payment Gateway:
The chosen gateway then handles the secure transfer. It encrypts the submitted payment data (card number, ACH details, etc.) and submits it to the acquiring bank for authorization.
The gateway also enforces security checks, CVV, OTP, 3D Secure and fraud rules. Once the bank approves the payment, the gateway captures the funds and credits them to a holding account.
You can think of authorization as the “green light” from the buyer’s bank, and capture as the actual transfer.
Settlement:
Finally, the money is settled to the merchant’s account. Typically, the processor holds the funds for a short “settlement period”, often 1–3 business days to allow for any chargebacks or refunds.
After this hold, the processor deducts its transaction fees and sends the net amount to the seller’s bank account.
For example, standard card transactions usually settle within 1–3 days.In B2B, sellers may also offer extended invoice terms, which further delay when they actually receive the cash.
