The verdict in three sentences
Accepting Net-30 payment terms at a B2B online checkout raises the average order value by 20 to 40% according to market feedback, because business buyers order more when they do not have to advance cash. To avoid carrying the risk, B2B buy now, pay later solutions grant a credit limit in seconds, guarantee the receivable and pay you within days for a fee of 1.5 to 4%. The choice is between three models: in-house credit, trade credit insurance or a B2B deferred payment fintech, and the right one depends on your gross margin and volume.
Three ways to offer payment terms online
In-house credit: you manage limits, invoices and reminders from your ERP. Lowest in fees, but you carry 100% of the bad debt risk and the cost of collections.
Trade credit insurance tied to your store: an insurer rates your customers and covers part of the losses (often 80 to 90%). You remain responsible for invoicing and dunning.
B2B deferred payment fintech: embedded in checkout, it checks the buying company in real time, pays you within D+1 to D+3 and handles collections. You pay a fee per transaction.
2026 solution comparison
| Criterion | In-house credit | Credit insurance | B2B deferred payment fintech |
|---|---|---|---|
| Direct cost | Internal dunning and collection costs | 0.1 to 0.4% of insured revenue + deductible | 1.5 to 4% of the amount depending on term and risk |
| Credit decision | Manual, 1 to 5 days | Insurer rating, 24 to 72 h | Automatic, a few seconds |
| Bad debt risk carried | 100% | 10 to 20% (uninsured share) | 0% on approved amounts |
| Cash flow | Collected at 30-60 days | Collected at 30-60 days | Paid D+1 to D+3 |
| Store integration | ERP development + customer portal | Light on the store side | API or checkout plugin, 1 to 3 weeks |
| Best for | Known key accounts, high margin | Stable portfolio, large volumes | New customers, SMB buyers, growth |
These ranges are 2026 orders of magnitude seen in the US, UK and European markets, not contractual offers. A fintech's fee varies with the term (30, 60 or 90 days) and your buyers' risk profile.
The legal framework: US and UK
Payment terms rules differ by market. Your store must display compliant terms and invoices.
| Rule (2026) | United States | United Kingdom |
|---|---|---|
| Default term | Contractual, Net 30 is the market standard | 30 days if no term agreed |
| Maximum term | No federal cap between businesses | 60 days, longer only if not grossly unfair |
| Late payment interest | Set by contract and state law, often 1 to 1.5% per month | Bank of England base rate + 8 points |
| Fixed recovery compensation | Not standard, contractual | GBP 40 to 100 depending on invoice size |
| Required wording | Terms on invoice and terms of sale | Terms on invoice and terms of sale |
In France, the cap is 60 days from invoice date with a fixed EUR 40 recovery fee, as detailed in the French version of this article.
Mini case study

- Conservative assumption: average order up 20% on those orders, or +GBP 4,160 of monthly revenue.
- Extra gross margin: 4,160 x 28% = GBP 1,165 per month.
- Fee cost: 2.5% x (20,800 + 4,160) = GBP 624 per month.
- Estimated net gain: about GBP 540 per month, before the effect of new customers won thanks to the option.
What integration costs
On the store side, you need an adapted checkout (payment method choice, company registration number, billing address), a customer portal with invoices and status sync back to the ERP. Depending on your platform, plan a few days for a ready-made plugin up to 2 or 3 weeks for a custom integration. On an application built with Kolonell, this component is priced within the scope (11/10/2026 grid: simple applications from 2,500,000 to 4,000,000 FCFA, i.e. EUR 3,810 to 6,100, medium from 4,000,000 to 7,000,000 FCFA, i.e. EUR 6,100 to 10,670).
FAQ
Does B2B deferred payment really raise the average order?
Market players report a 20 to 40% increase in average order value on eligible orders. Use the low assumption, 20%, to build your business case.
Who chases the customer if they pay late?
With a deferred payment fintech, the provider handles reminders and collections, and you are paid within 1 to 3 days. With in-house credit, your team does it, with interest set by contract or by law.
Can we offer Net-60?
Yes, within local limits, for example 60 days in the UK unless justified. The fee usually rises by 1 to 1.5 points compared with Net-30.
What if a buyer is declined?
Checkout automatically offers card or transfer at order. In practice, 10 to 25% of requests are declined depending on portfolio quality.
Is there a minimum margin for this to pay off?
With a 1.5 to 4% fee, a gross margin below 15% makes the equation fragile. Above 25%, the order value gain easily covers the cost.
