B2B Payments

B2B Payments Are Becoming Programmable. Here’s What Comes Next

A supplier submits an invoice. The invoice is approved. Then the payment waits.

It waits for the next payment run, banking hours, settlement windows, and often for multiple financial institutions to process the transaction before funds reach the recipient. By the time a supplier receives cleared funds, weeks may have passed since the invoice was submitted. For many businesses, this delay is treated as a normal part of operating. In reality, it is the product of payment infrastructure built around batch processing, banking schedules, and intermediary networks.

B2B payments account for the majority of stablecoin payment activity globally, and B2B stablecoin volumes grew more than 700% year-over-year in 2025. Enterprises are moving supplier payments, embedded working capital, and cross-border money movement onto stablecoin rails because the difference in cost, speed, and operational efficiency is becoming increasingly difficult to ignore.

Why Enterprise Payments Remain Expensive

The global B2B payments market exceeded $11 trillion in annual volume in 2024, yet much of the infrastructure supporting those transactions remains dependent on banking hours, batch processing, correspondent banking relationships, and delayed settlement. International wire transfers often cost between $15 and $50 per transaction before correspondent banking fees, FX spreads, and intermediary charges are factored in. For smaller cross-border transactions, total costs can reach 3% to 5% of payment value.

Transaction fees are only part of the problem. The deeper structural constraint is timing: suppliers want to be paid immediately, buyers need 30, 60, or 90 days to preserve working capital, and platforms want the transaction to happen without becoming lenders or tying up capital from their own balance sheets. 

In today's infrastructure, that tradeoff is usually absorbed by one party or resolved outside the payment system entirely. By 2025, 77% of enterprises adopting stablecoin payments cited cross-border B2B settlement as their primary use case. Three layers of this problem are now being solved onchain: the credit gap between approval and settlement, the liquidity behind card programs, and the reconciliation work that follows payment.

OatFi and the Credit Layer Inside B2B Payments

OatFi provides one of the clearest examples of how B2B payments are being upgraded from simple money movement into embedded working-capital infrastructure. The platform enables businesses to offer financing directly inside B2B payment workflows, so that suppliers can receive liquidity earlier, buyers can preserve payment flexibility, and platforms can offer working-capital products without building a lending business from scratch.

The problem OatFi addresses is structural rather than technical. Invoice approval and payment settlement are separate events, and the gap between them creates a working capital burden that falls on someone in the transaction. OatFi addresses that gap by embedding underwriting, ledgering, funding, and repayment directly into the payment flow, so that credit decisions and settlement activity happen together rather than across disconnected systems. 

Payment obligations, financing terms, and repayment are represented and coordinated onchain, with stablecoin settlement moving through Avalanche, and onchain records cutting the reconciliation burden that typically follows.

The result is a model in which payment and credit operate within the same flow rather than across separate infrastructure layers, which simultaneously changes the economics of B2B commerce for platforms, buyers, and suppliers.

Rain and the Working Capital Behind Card Programs

Rain shows a different side of the B2B payments opportunity: the liquidity and settlement infrastructure that sits behind card programs rather than in front of them. For fintechs, exchanges, wallets, and payment companies, the end-user experience of a card transaction looks simple. Behind it is a financial workflow that determines how the program is funded, how settlement obligations are met, and how liquidity is managed across digital assets, stablecoins, fiat accounts, and card networks.

Rain provides card issuing and payment infrastructure that helps businesses launch stablecoin-powered card programs on Avalanche. As these programs scale, managing the working capital required to fund settlement obligations becomes a B2B finance problem in its own right: payment companies need to coordinate liquidity across multiple balance types before settlement cycles close, without disrupting the card experience for end users. 

Avalanche's sub-second finality and low settlement cost let payment companies fund and reconcile card obligations within a single cycle, rather than pre-funding against legacy banking windows: a more efficient path to managing card-program capital than legacy funding cycles allow.

Managing Accounts Payable and Finance Operations Onchain

Request Finance provides invoicing, accounts payable, accounts receivable, and reconciliation infrastructure via its Avalanche integration, enabling businesses to manage supplier payments and financial operations on a unified platform. 

Request Finance has processed more than $1 billion in payment volume across its platform, with its Avalanche integration settling supplier payments in digital dollars. It supports invoice creation, payment tracking, batch disbursements, and reconciliation for organizations managing both crypto-native and traditional counterparties.

Faster settlement only delivers its full value when the operational workflow around the payment improves alongside it. A payment that moves in seconds but still requires manual invoice matching and delayed accounting updates has not fully solved the enterprise problem. Request Finance addresses the full payment lifecycle, from invoice creation through settlement and reconciliation, within a single environment that settles through digital dollars on Avalanche.

B2B Stablecoin Payments Are Moving Into Production

The infrastructure for B2B stablecoin payments is already operating in production across embedded working capital, supplier payments, invoice settlement, accounts payable operations, and card program settlement. 

What the shift enables is moving funds when a payment is approved, rather than when banking infrastructure becomes available, and coordinating credit, settlement, and reconciliation within the same workflow rather than across separate systems.

For organizations evaluating B2B payments infrastructure, Avalanche already settles institutional-scale flows in production (embedded credit through OatFi and Valinor, card-program liquidity through Rain, and full-lifecycle AP/AR through Request Finance) with onchain settlement that legacy banking cycles can't match in speed or cost.
