B2B invoice payment portal with card and bank transfer in Amsterdam (2026)

The verdict in three sentences

For an IT hardware distributor in Amsterdam still chasing unreferenced bank transfers, a B2B invoice payment portal is the investment that frees cash fastest, because it removes the days lost between invoice delivery and actual collection. The 2026 Dutch market ballpark is 25,000 to 45,000 EUR for a portal with a payment link on every invoice, iDEAL and SEPA options and automatic reconciliation with accounting, delivered in 10 weeks. A realistic target is DSO down by 20 days within 6 to 9 months, with fees from a few cents per iDEAL payment to about 2% on cards.

Why plain bank transfers cost more than they seem

The CFO of a distributor in Amsterdam Westpoort knows the flow: the invoice goes out by email, the customer's accounts payable team queues it, a transfer arrives 25 days later with a reference like “inv march”, and someone must work out which of three invoices a payment of 7,140 EUR is meant to settle. Across 3,000 invoices a month, that matching often keeps two credit controllers busy full time, even with modern Dutch banking.

The portal does not replace transfers for large amounts: it makes them traceable with a unique structured reference per invoice.

What a B2B payment portal includes

The core is a unique payment link on every invoice, printed as a QR code on the PDF and sent by email. The customer clicks, sees open invoices, picks one or several and chooses a method. Each payment comes back by webhook, is matched automatically to the right invoice in the accounting system (Exact Online, AFAS, Twinfield, NetSuite) and triggers a receipt.

Fees can be absorbed, passed on or steered: for example, iDEAL free for the customer, card with a surcharge where allowed for business cards. Many distributors offer a 1% discount for payment within 8 days, which is cheaper than 20 days of credit line at 6 to 7% per year.

Mini case study

Marieke, CFO of an IT distributor in Amsterdam, issues 3,000 invoices a month for monthly revenue of 4,500,000 EUR. Her DSO is 52 days. Bringing it to 32 days frees 20 days of revenue, or roughly 3,000,000 EUR of cash. At a 6.5% credit line rate, the interest saving reaches 195,000 EUR per year. She keeps large invoices on structured SEPA transfers and steers smaller ones to iDEAL at about 0.30 EUR each: on 2,100 iDEAL payments a month, fees total around 7,600 EUR per year, plus about 16,000 EUR of card fees on the 1.5% of value paid by card. One credit controller moves to credit risk analysis. The second controller now spends most of her time on the 40 largest accounts, which represent about 55% of receivables. For a 38,000 EUR portal, the net first-year gain exceeds 130,000 EUR.

FAQ

Will large corporate customers pay online?

Large accounts usually stay on transfers, but with the portal's structured reference, which is enough to automate matching. SMEs, often 70% of invoices by count, adopt iDEAL within 2 to 3 months.

Do we need to change accounting software?

No, the connector works with Exact Online, AFAS, Twinfield or NetSuite through their APIs. It is the component that varies most, from 6,000 to 11,000 EUR.

What about partial payments?

The portal accepts them if you allow it, matches the amount paid and leaves the balance open. The next reminder covers only the remaining amount.

Is e-invoicing relevant here?

Yes: with the EU push toward structured e-invoicing and Peppol already common in Dutch B2B, the payment link can be embedded in the e-invoice. Plan 1 to 2 extra weeks if Peppol delivery is in scope.

How fast does DSO move?

First effects appear in 6 to 8 weeks, mainly on SMEs. The full 20-day reduction is usually measured between month 6 and month 9.
