The verdict in three sentences
On a B2B e-commerce site, a trade buyer who cannot find 30-day terms abandons the basket or calls their sales rep instead. B2B BNPL solves this for 1.5 to 3.5% per transaction: the seller is paid within 1 to 2 days, the provider carries the bad-debt risk, and average order value usually rises by 20 to 35%. Integration costs GBP 2,500 to 8,500 as a 2026 order of magnitude, within UK rules that treat 60 days as the normal ceiling for agreed terms.
Options for selling on terms online
A catering supplies wholesaler in Park Royal sells to 2,000 trade accounts across London: cafés, restaurants, hotels and contract caterers. Over the phone, known customers have always paid on 30 days end of month. On the website, only card is offered, so the restaurant ordering GBP 750 of tableware and small equipment waits for the rep's next visit. Four routes open up trade credit online.
| Solution | 2026 cost order of magnitude | Who carries the risk | Cash timing for the seller | Internal effort |
|---|---|---|---|---|
| In-house credit, uncovered | No fees, losses of 1 to 3% of receivables | Seller | 30 to 60 days | High: scoring, chasing, collections |
| In-house credit with trade credit insurance | 0.1 to 0.4% of insured turnover | Insurer, after excess | 30 to 60 days | Medium: declarations, buyer limits |
| Invoice finance (factoring) | 0.5 to 1.5% fee, plus interest | Factor (non-recourse) | 1 to 3 days after assignment | Medium: invoice submission |
| B2B BNPL at checkout | 1.5 to 3.5% per transaction | BNPL provider | 1 to 2 days | Low: instant credit decision |
| Card payment up front | 0.8 to 1.8% | Nobody | 1 to 2 days | Low, but lost baskets |
B2B BNPL stands out for its credit decision in seconds at checkout, based on the Companies House number, credit score and trading history. The buyer gets an invoice payable at 30 or 60 days, and the seller is paid almost at once. The wholesaler no longer has to set a credit limit for a restaurant that opened eight months ago.
What each payment term costs
Fees depend mostly on term length and buyer size. A young sole trader costs more to cover than a hotel group.
| Term offered to the buyer | Merchant fee (2026 order of magnitude) | Typical use | Compliance |
|---|---|---|---|
| Pay in 14 days | 1.5 to 2% | Weekly restock | Fine |
| Pay in 30 days | 2 to 2.5% | Hospitality standard | Fine |
| 45 days end of month | 2.5 to 3% | Chains and groups | Fine |
| 60 days from invoice | 3 to 3.5% | Large equipment | Fine, normal ceiling |
| Split into 3 instalments | 2.5 to 3.5% | Opening fit-out | Fine if instalments stay within terms |
Under the Late Payment of Commercial Debts (Interest) Act 1998, terms above 60 days between businesses are only valid if they are not grossly unfair to the supplier. Late invoices carry statutory interest of 8% above the Bank of England base rate, plus fixed compensation of GBP 40 to 100 per invoice. BNPL does not make 90-day terms a safe default.
On the technical side, integration covers the payment module in checkout, invoice sync with accounting, returns and credit notes, and credit limits displayed in the customer account. Count GBP 2,500 to 8,500 depending on whether the site runs on a standard platform (existing plugin) or a custom build (API work). At Kolonell, this work is priced in the quote for your e-commerce project.

Recovered baskets lift volume to 3,300 orders. The 1,650 orders on terms rise to GBP 625 on average (+25%), the other 1,650 stay at GBP 500. New revenue: 1,650 × 625 + 1,650 × 500 = GBP 1,856,250, or GBP 356,250 more. At a 25% gross margin, that is GBP 89,063. BNPL fees at 2.5% on GBP 1,031,250 cost GBP 25,781, and integration GBP 5,000. Year-one result: about GBP 58,300 of extra margin, with no invoices to chase.
FAQ
Can the BNPL provider decline one of my customers?
Yes, the decision is made in real time and 5 to 15% of requests are declined or capped depending on the provider. The buyer is then offered card or bank transfer at checkout.
What if my customer never pays?
With non-recourse BNPL, the provider takes the loss and handles collection. Check the terms: some contracts allow recourse when there is a dispute about the goods.
Can we keep current terms for key accounts?
Yes. The 50 to 100 legacy accounts can keep their 30 days end of month in the ERP, with BNPL serving new customers and accounts without a credit limit.
Does BNPL replace trade credit insurance?
For online sales it complements it. Insurance at 0.1 to 0.4% of turnover stays relevant for negotiated offline deals.
How long does integration take?
Two to three weeks on an existing plugin, four to six weeks on a custom platform with accounting sync.
