Also written as BillToBox, Banqup.

Measured by our own probes · data as of 20 Sept 2026, 19:30 UTC

Language EN NL FR

Question 1

Does Billtobox do Peppol?

Yes. Billtobox's Peppol traffic runs on Banqup SA's certified access point — Billtobox does not hold a Peppol certificate of its own, and it does not need one.

How we know Vendor documentation

Two steps, both checkable. First: Unifiedpost's own product page says Billtobox runs on Unifiedpost Group's own network. Second: the Unifiedpost access point we resolve in Belgium is the one certified to Banqup SA, and our own reseller catalogue finds Unifiedpost named alongside its endpoints — so that is the certificate behind Billtobox.

Question 2

Which access point serves Billtobox?

Banqup SA, a Peppol operator in Belgium, runs the access point that Billtobox's documents pass through. Banqup SA is on OpenPeppol's certified service provider list.

Question 3

How big is the access point behind it?

108,717 on Banqup SA's access point

108,717 Peppol participants are registered on Banqup SA's access point. That is the operator's total across every product riding its certificate, not a count of Billtobox customers, and we have no way to split it by product. Read it as the size of the infrastructure behind Billtobox, nothing more.

That makes Banqup SA #20 of 340 Peppol providers worldwide by participants served.

Question 4

Is Banqup SA reliable?

74.98%

Over the last 30 days we measured 74.98% uptime on Banqup SA's Peppol endpoints, from our own probes in several regions rather than a status page the operator writes about itself. If Billtobox cannot deliver an invoice, this is the number that explains it.

3 incidents recorded in that window — worst host ws-acc.zfactuur.nl.

Question 5

How do I find my Peppol ID?

Your Peppol ID is not something Billtobox invents for you. It is your own company number, written behind a four-digit ISO 6523 prefix that says which national register the number comes from: in Belgium that prefix is 0208 for the KBO/BCE enterprise number, or 9925 for the VAT number.

Build yours, then look it up in the Peppol Directory — if it resolves, you are registered and reachable; if it does not, you are not on the network yet, whatever any dashboard says. The prefixes for every market are in the table there.

What this page is, and what it is not

Everything above comes from one of two places. The figures — participants, uptime, endpoints, certified status — are our own continuous measurements of the live Peppol network, taken 20 Sept 2026, 19:30 UTC. The link between Billtobox and Banqup SA comes from first-party documentation from the company that runs the registration, linked above — we are relaying that claim, not measuring it, which is why the source is there for you to check.

We are not Billtobox, we have no commercial relationship with Billtobox, and nothing here is taken from Billtobox's marketing. Equally, nothing here describes what the product looks like from the inside: for pricing, features and the steps to switch Peppol on, read Billtobox's own documentation. Where the two disagree, the vendor knows its product and we know the network.
