UBL invoice UBL (Universal Business Language) is a fixed XML format for invoices, where every detail has its own field: supplier, lines, VAT, total. In the Netherlands that is usually **SI-UBL**, based on UBL 2.1. The file often comes as an .xml attachment next to the PDF: the PDF is for people, the XML for software.

One condition: the same file name, such as factuur-123.pdf and factuur-123.xml. 2. 02Glimps reads the XML and puts it next to the PDFThe data comes from the XML. Glimps reads the PDF too, and flags it when the two do not say the same thing. 3. 03The normal route to Exact OnlineAfter that it is an invoice like any other: coding, the checks for duplicates, a changed bank account and the math, approval, and posting in Exact Online. ### Which route reads the XML? Not every way into Glimps takes the XML along. This is how it works: - Upload: PDF and XML together Both the XML and the PDF are read - Connected Microsoft 365 mailbox Both the XML and the PDF are read, when they share a name - The Glimps mail address Only the PDF is read - Only an XML, without a PDF Does not become an invoice Mailing through the Glimps mail address? Then the invoice still comes in through the PDF. If you want the XML to count, upload the PDF and the XML together. ## What Glimps takes from the UBL file In an XML everything sits in its own field. So Glimps has nothing to guess, it simply picks up the value. ### The supplier Name, VAT number and Chamber of Commerce number, as the supplier filled them in. ### The IBAN The bank account from the XML goes through the same bank account check as any other invoice. ### Invoice number and dates Exactly as the supplier recorded them. No 0 that turns into an O. ### Lines, amounts and VAT Every invoice line with its amount and VAT, ready to be coded. ### Order references per line When the XML carries an order number per line, Glimps takes it along. Handy if you use [PO matching](https://useglimps.com/en/matching). ### Service periods When a line covers a period, such as a subscription for a quarter, Glimps reads that period too. That goes for invoices and credit notes, in UBL 2.1 and the Dutch SI-UBL. ## The XML counts, the PDF checks along Glimps goes by the values in the XML. But it reads the PDF too, because sometimes the supplier says something different in the PDF than in the XML. You want to know that before you pay. - An amount that differs by more than 5 cents stands out. - A different invoice number on the PDF stands out too. - Glimps flags the difference on the invoice, so someone takes a look. factuur-VD-2026-0412 FieldXMLPDFInvoice numberVD-2026-0412VD-2026-0412Total excl.

It does not send or receive anything over the Peppol network. ### No UBL output Glimps reads UBL files, but does not create or export them. ### No XML without its PDF A UBL file on its own does not become an invoice. Send the PDF along, under the same file name. Only have an XML? Ask the supplier for the PDF as well, or mail just the PDF to your Glimps mail address. ## Questions about UBL invoices Want to try Glimps yourself?Try the demo What is a UBL invoice?
