Click Sales invoice in the sidebar and select New invoice. You enter the invoice form with two tabs: Document (the invoice details) and Attachments.

Self-service: sending is fully self-service. eConnect does not upload or send invoices on behalf of the customer. This also applies to activated foreign suppliers. After activation they follow the same flow (Sales invoice → New invoice, or upload existing XML) as Dutch organisations. The platform language is Dutch. You can switch to English via Edit profile (top right in the platform). Before login, a language choice is available on the login page.

Test invoices and ACC tenants: eConnect does not invent, create or prepare test invoices in customer or third-party ACC tenants, including the recipient's tenant. You test yourself, self-service, via the platform or via the PSB API/Swagger. See Send an invoice via the API. Use real or sample supplier details in the UBL/XML you submit. eConnect does not fill these in on your behalf.

• Supplier: your own organisation. This field is not filled automatically. Choose your organisation from the drop-down. Do you not see your organisation in the list? See below.
• Debtor (recipient): search by Chamber of Commerce number, company name or OIN via Search organisation. The platform automatically searches the Dutch Chamber of Commerce database and the Belgian KBO to retrieve the correct details. There is no separate address book for frequent customers: for each new invoice you look up the customer again via Search organisation, which is as fast as browsing an address book. If you regularly invoice the same one or two customers, save them in a draft invoice that you reuse as a template.

Search variants: Send via; Organisation ID; Luxembourg 9938; EAS 9938; prefix 9938; GLN without prefix; 0088 is not an OIN; identifier without scheme prefix; upload PDF invoice.

You enter a foreign Peppol recipient only on the invoice, via the debtor field (Send via + Organisation ID). Do not add the recipient as your own organisation in the account.

For Luxembourg the identifier is EAS 9938 (VAT number). Scheme and value must match the recipient's Peppol registration. See What is my Peppol ID?.

Enter a GLN (scheme 0088) as 13 digits, without the prefix 0088:. Scheme 0088 is not an OIN (0190).

• Invoice number: generated automatically if you have set automatic numbering. Otherwise enter a number manually.
• Invoice date: today by default, but editable.
• Invoice type: choose the invoice type from the drop-down. The default is a regular invoice. For a credit note choose "Corrective invoice". See Send a corrective invoice.
• Invoice lines: add one or more lines with description, quantity, unit price and VAT rate. Available VAT rates are built dynamically from the supplier country and the customer country. For a customer in another EU country the option "Exempt for intra-Community supply" appears automatically. For a customer outside the EU the option "Export" appears.

If a rate is missing from that dropdown, there is no workaround in the form. eConnect maintains the list.

Search variants: "Correct VAT set up Norway", "BTW percentage Noorwegen dropdown", "VAT rate Norway branch", "VAT set up entity Norway".

Search variants: upload invoices; invoice upload fails; upload PDF invoice platform; how to submit an invoice; upload XML or PDF; how uploading works; invoice upload menu; fewer menu items invoice portal; New invoice heading missing; incomplete menu after activation; temporary delay Sales invoice menu; New invoice not in menu; how to create invoice Sales invoice; send my invoice; send PDF invoice by email; purchase invoices or draft invoices; wrong email receiver type; not a trusted sender but I want to send; submit invoice after activation; create draft invoice email receiver; Processing is not possible.

There are two paths to get an existing invoice into the platform:

1. Sales invoice → New invoice (this screen): upload an existing XML invoice here. It is read into the form automatically. On this screen a PDF is not the main invoice. You can only add a PDF as an attachment, on the Attachments tab.
2. PDF-only path via Email Receiver: do you only have a PDF invoice without XML? Email it to your own Email Receiver address with document type Draft invoice (requires at least a Basic subscription). After conversion the invoice appears under Sales invoice → Draft invoices, where you check and complete the details before you save and send. See Email receiver and Set up Email Receiver. Problems during submission: Sending errors.

Separate the intent (first line): "I want to send my invoice" is not the same as receiving purchases or emailing someone else's address.

@inkoopfacturen.econnect.eu / Document Context Purchase invoices is for receiving and converting purchases, not the default path to send your own sales. Do you get "Processing is not possible" or "not a trusted sender" after emailing the wrong type or someone else's purchase address? First correct the path and type to Draft invoice on your own receiver. A whitelist does not solve "send from my account" when the intent is your own sales.

Search variants: "organisation disappeared", "I am not part of the organisation", "not part of the organisation", "No access – You do not have permission to send this document. You are not a member of the organisation", "no access when sending invoice", "no permission to send this document", "you are not a member of the organisation", "XML from another environment", "cannot do anything in the portal anymore", "cannot do anything at all".

Do you notice this mainly on a (often the first) draft invoice, and does it feel like a total block? The exact platform message when sending can be: "No access – You do not have permission to send this document. You are not a member of the organisation". That sounds like a rights or account problem, but the organisation usually still exists. Check the Supplier selection first (and, for uploaded or emailed XML, whether that XML comes from another environment) before you assume a membership problem. This is not organisation deletion.

Choose your organisation in the supplier field via the drop-down. If your organisation is not in the list, you cannot select your own organisation as sender. Without supplier details you cannot save or send the invoice.

Three common causes:

1. Organisation not selected: if you have several organisations in your environment, indicate which organisation you send from.
2. Organisation not activated: an added but not yet activated organisation cannot be used as supplier.
3. No organisation membership: you are a member of the environment, but not of the organisation. Without membership the organisation usually does not appear under My organisations (it may appear under All organisations) and it is not selectable as Supplier. Activation alone does not fix this. An organisation administrator must add you as a member first. See Rights and roles.

Click the pencil next to the supplier field and select your organisation. Is your organisation not in the list? First check whether you are a member via My organisations, then the activation status via My environment > Organisations. Complete activation if needed via Add and activate an organisation. After selection your company details (name, address, Chamber of Commerce number, VAT number) are filled in automatically.

The platform links accounts automatically to the environment of the email domain. Anyone who logs in with an address on @organisation-A.nl lands in the A environment (or is added there as a basic user/guest). Invoicing on behalf of organisation B is only possible if:

1. B exists as an organisation in the environment and is activated, and
2. you are a member of B (rights on B). See Rights and roles.

Only an environment administrator may add organisations. Support does not add an organisation without that administrator's permission.

Two routes

1. Own environment for B (recommended if B should be separate from A): create an account with email on a domain of B's own (not the A domain). Add organisation B via Chamber of Commerce (Add organisation) and activate B. Then: Sales invoice → New invoice and select B as supplier. See Add and activate an organisation.
2. Inside the current A environment: the administrator of A adds B, activates B and links you as a member of B. Support does not do this on its own.

Sales invoice / New invoice button missing, or empty supplier field: usually no membership of an activated sending organisation, or the desired organisation is not in the environment. The supplier field is a drop-down of your own activated organisations (not free text). See Supplier empty and the section The supplier field is empty. Is the organisation activated but do menu items or the Sales invoice app stay missing for a while? Refresh the page first or wait a moment (sometimes a temporary delay after activation). If it stays missing, log in again. After activation a fresh session is sometimes required. See Add and activate an organisation.

Do not confuse with: adding the recipient/debtor as "own organisation". You select recipients via the debtor search field (Search organisation), also when the recipient is a customer or a government body (OIN). Do not add the customer's or municipality's organisation as your own organisation. Enter the recipient's OIN as debtor on the invoice itself.

Search variants: "add organisation" on an invoice, add own organisation separately, debtor as own organisation, add invoice recipient to environment, activate government debtor organisation, recipient must be in the environment, register under municipality OIN, customer OIN as own organisation, invoice a municipality with own OIN, recipient OIN is not own identifier, scheme 0190 debtor.

The invoice form contains optional fields you can fill in depending on the recipient's requirements:

• Order number: the recipient's purchase order number. Many large companies and public bodies require the order number on the invoice. Without an order number the invoice is sometimes rejected automatically. Note: at least one of Order number and Buyer reference must be filled in. If both are missing, you cannot save the invoice.
• Delivery date: the date the goods or services were delivered, if it differs from the invoice date.
• Project number: a reference to the project the invoice is for. Useful if you invoice per project.
• Contract number: a reference to the underlying contract.
• Invoice note: a free text field for extra information on the invoice, visible to the recipient.
• Start date / End date: the service period the invoice covers. Use this for recurring services or subscriptions.
• Buyer reference: a reference the recipient recognises, for example a cost centre or department. When invoicing the Dutch government this field is essential. Enter the routing code the government organisation requires.

Tip: invoicing the government or a large company? Always ask which reference fields they require. An invoice with a missing order number or routing code is often rejected automatically.

Not all UBL fields are available in the invoice form:

• BT-46 (Buyer Identifier): for the Greek Contracting Authority Code (HT: ..., for example when invoicing the wider public sector) an input route has been available since the platform release of 10/11 May 2026 via Organisation ID → Other (DE UI: Organisations-ID / Sonstige). This field is separate from the VAT number (debtor VAT) and from Send via + Organisation ID (the Peppol routing field). Do not mix these three identifiers. See Greece for details. Other BT-46 scenarios outside this route still require the XML/API flow.
• BT-158 (Item Classification / CPV code): not available in the invoice form.

Organisations that need these fields cannot currently solve this via the standard platform interface. Contact support for an alternative submission method.

Via the link Add delivery details you can include specific delivery information, such as a delivery address that differs from the invoice address. This is mainly relevant for physical deliveries or invoicing another branch.

On the Attachments tab you add extra files to the invoice. A regular invoice is a Peppol BIS V3 message. Only the following attachment formats are allowed:

Export a Word document to PDF before you add it as an attachment.

Limits: maximum 9 MB of attachments per invoice. For CSV files a stricter limit of 6 MB applies. Peppol technically allows up to 100 MB, but the advice is to keep to a maximum of 10 MB per invoice. When sending to the Dutch government a maximum of 10 separate attachments applies. eConnect can merge attachments on request. The order of the merged attachments is arbitrary.

Attachments are sent with Peppol delivery (embedded in the UBL message) and with email fallback (as a separate file in the same email as the invoice PDF).

Before you send, you can review the invoice:

• Company logo: if you have set a logo in the organisation settings, it appears automatically on the PDF view.
• PDF preview: see how the invoice looks for the recipient by clicking Preview.
• Internal comments: add a comment visible to all users with access to the document. Note: if you are the supplier and your customer also has access to the eConnect platform, your customer can see this comment too. Be discreet in what you enter here.

Search variants: process and send a sales invoice correctly; send invoice via Peppol; how to create a sales invoice on the platform; New invoice Peppol; explanation send invoice to customer.

At the top of the form you find three buttons:

• Save: save the invoice as a draft without sending
• Send: send the invoice immediately
• Share: share the invoice with a colleague or partner for review, without sending. Useful if someone else must check the invoice before it is sent.

Click Send to send the invoice. The platform automatically selects the best delivery channel via the #PeppolFirst principle:

1. Peppol (external network): the primary and recommended route. The platform automatically checks whether the recipient is on Peppol and delivers the invoice as an e-invoice.
2. Email fallback: if the recipient is not reachable via Peppol, the platform sends an email with the invoice. In the account settings you can choose which files are attached: PDF only, PDF + XML, XML only, or no attachment.

After sending, the invoice appears in your Outbox with a status overview.

Create a credit note for the incorrect amount. This offsets the incorrect invoice.

Then create a new invoice with the correct amount and send it to the recipient.
