B2B payments explained: methods, process, and risk

B2B stands for business-to-business — any transaction where one company sells goods or services to another company. Think of a manufacturer paying a supplier, or a software vendor billing a corporate client.

B2C stands for business-to-consumer, covering transactions between a business and an individual buyer. A customer purchasing from an online retailer is a straightforward B2C example.

The two models differ in more than just who is on the other side of the payment. B2B transactions typically involve longer payment cycles, formal purchase orders, and negotiated credit terms. B2C payments tend to be immediate, simpler, and settled at the point of sale.

A B2B payment is money moving from one business to another, usually settling an invoice for goods or services already supplied. It can happen instantly, like a card payment, or take weeks, if a customer's paying on agreed credit terms.

A consumer pays for something once, usually on the spot, and that's the end of it. A B2B payment often works on credit. You supply now, and your customer pays later, under terms you've agreed between you. That single difference changes everything about how you manage cash flow, since money owed isn't the same as money in the bank.

B2B transactions also tend to involve much larger sums than a standard consumer purchase, and they are often ongoing. You're usually building a relationship with the same customer over time, which means the risk of a payment going wrong doesn't just affect one sale but can affect every order that follows. That's why understanding your cash flow matters even more in B2B than it does in consumer sales.

This is also where a payment schedule and payment terms come into play. The schedule sets out when your customer will pay, and the terms set the conditions behind it. Both work along with the payment method you choose to determine how smoothly, and how reliably, you actually get paid.

There are many B2B payment solutions available, each suited to different situations, including:

• Bank transfer: This is the default for most business payments in the UK, moving money directly between bank accounts. Faster Payments grew quickly enough that it overtook Bacs Direct Credit as the most-used payment method amongst businesses back in 2021, according to UK Finance. By 2024, half of all business payments were made this way, which suggests that speed now matters as much as cost when businesses choose how to pay each other.
• Direct debit: This method is suited to recurring payments, where a customer authorises you to collect an agreed amount on a set date. Common for subscriptions, retainers, or regular supply arrangements where the amount rarely changes.
• Card payment: Card payments are quick and familiar, though card fees can eat into margins on larger business transactions. This method is more common for smaller purchases or businesses without an established credit relationship.
• Invoice financing: With this method, you borrow against the value of an unpaid invoice, rather than waiting for a customer to pay. This can free up cash tied up in outstanding payments, though it comes at a cost, and you should weigh it up against simply managing your payment terms more tightly.
• Buy Now Pay Later: This is a newer option in B2B that lets your customer spread the cost of a purchase while you get paid upfront. BNPL has many business advantages and so it's becoming more established in the UK as a genuine alternative to traditional trade credit. However it works differently to consumer BNPL, which has been under new FCA regulation since July 2026.

Let’s look at how B2B payments work:

1. Order: The customer places an order, and you confirm it, including what's being supplied, at what price, and on what terms.
2. Invoice: Once you've delivered the goods or completed the work, you raise an invoice setting out what's owed and when.
3. Payment: The customer pays by bank transfer, card, or whatever method you've agreed.
4. Reconciliation: You match the payment against the original invoice to confirm it's settled in full. This step is easy to miss, but it's what catches a short payment, a missing reference, or an invoice that's slipped through unpaid.

Here are a few real-world scenarios that show how B2B payments work in practice.

A UK wholesaler supplying a retail chain might issue invoices on net 30 terms, with the retailer settling via bank transfer once the goods arrive and are checked. A SaaS company billing business customers monthly would typically use direct debit, automating collection so neither side has to think about it.

For cross-border deals — say, a manufacturer paying an overseas supplier — wire transfers are common because large sums need to move quickly and securely across currencies.

A smaller supplier working with a slow-paying corporate client might turn to invoice financing, drawing funds against unpaid invoices to keep cash moving rather than waiting 60 or 90 days for settlement.

Each scenario involves a different method, but the underlying challenge is the same: getting paid reliably, on time, without unnecessary friction.

Every method of getting paid carries its own level of risk. A card payment settles instantly, but bank transfers and invoice financing put you in a position where the money's owed before it's actually in your account. The longer that gap, the more exposed you are if a customer runs into trouble.

That gap is real money for a lot of UK businesses. Late payments cost UK small businesses around £22,000 a year on average and are linked to an estimated 50,000 business closures annually, according to government figures.

Offering more payment options can also work against you, if you're not careful. It's true that flexibility drives sales (see our guide on how payment flexibility drives growth in B2B e-commerce for more on that) but every option you add is another payment method to manage, chase and reconcile. The convenience that wins you the order isn't the same thing as the certainty of getting paid for it.

Fraud is another risk you should consider when it comes to payments. Payment diversion, forged invoices, and impersonation scams (like a fake "urgent payment" request that looks like it's from a supplier or your own CEO) can slip through even a well-run payment process, especially as these scams get more convincing. Business Fraud Insurance covers losses like these, as well as the fraud that can come from within a business itself.

The worst-case scenario is that unpaid invoices become bad debt. Find out what that means for your business, and what you can do about it, in our guide to bad debt.

UK businesses made around 7.6 billion payments in 2024, of which 4.6 billion went to other businesses rather than consumers.

B2B digital payments are only becoming more common as businesses move away from batch-processed methods towards instant transfers. As a result, UK Finance forecasts Faster Payments and other remote banking to keep growing over the next decade.

For your business, this means the payment methods your customers expect are shifting towards faster, more direct routes. Consequently, you should keep your own invoicing and payment setup aligned with where the market's heading rather than where it's been.

Choosing the right solution comes down to what your business actually needs — transaction size, payment frequency, and how much admin your team can absorb.

Here are the main categories worth considering:

• Bank transfer platforms (such as Faster Payments, CHAPS, or BACS): reliable for high-value or recurring B2B payments, with low fees and strong traceability.
• Digital payment platforms: Tools such as payment gateways and ACH payment processors automate the reconciliation process and significantly reduce manual errors. These platforms are particularly useful if you handle high transaction volumes, as they provide real-time visibility across the entire payables and receivables cycle. By integrating B2B payment networks directly into your digital banking or ERP system, you can streamline your financial operations, improve security through encrypted data, and benefit from faster settlement times compared to traditional manual bank transfers.A significant development in this space is the partnership between Allianz Trade and Stripe. This collaboration integrates Stripe’s programmable financial infrastructure into the Allianz Trade pay solution, transforming the entire order-to-cash journey. For B2B merchants and marketplaces, this means you can automate everything from order validation to cash collection. Buyers can pay via secure payment links, while the system handles reconciliation automatically, providing you with a real-time dashboard to monitor all activity. Crucially, this setup combines secure B2B Payment Processing with real-time risk assessment—if a buyer fails to pay, Allianz Trade’s automatic indemnification steps in to protect your cash flow.
• Invoice financing: lets you release cash tied up in unpaid invoices, without waiting on customer payment terms.
• Trade credit insurance: protects your cash flow if a customer doesn't pay — worth considering alongside whichever payment method you use.

No single solution fits every business, so finance teams may use a combination.

Every B2B payment carries some risk in the gap between delivering the work and the money landing in your account. You can pick a fast, reliable method that will help, but it's not a guarantee.

Credit management fills that gap as it means you know who you're extending credit to and how much risk that represents, before the payment is even due. Find out what credit management involves and what it can do for your business.
