Electronic Invoicing with Sproom

Electronic Invoicing with Sproom by Abakion connects your Microsoft Dynamics 365 Business Central with the Sproom service to send electronic invoices and credit memos in the OIOUBL format. In Denmark, public-sector organizations and many private companies require invoices to be delivered as structured electronic documents — and this app makes that possible directly from Business Central.

Feature Overview

Business Central can generate sales invoices as PDF documents and send them by email, but it cannot deliver invoices in the OIOUBL electronic format required by the Danish public sector out of the box. Electronic Invoicing with Sproom bridges this gap by sending OIOUBL-compliant electronic invoices and credit memos through the Sproom e-invoicing platform. The app integrates with Business Central's standard OIOUBL functionality, enriches the generated XML with additional data such as file attachments, PDF copies, FIK payment references, and comment lines, and transfers the document to Sproom for delivery to the recipient.

To use this app, you also need a subscription with Sproom. Sproom offers several pricing tiers, including a free plan for low-volume senders.

Typical Use Cases / User Stories

A Danish company that invoices public-sector customers needs to send OIOUBL electronic invoices as required by law, and wants to do so directly from Business Central without exporting files manually.
As a finance manager, I want electronic invoices sent automatically when we post and send a sales invoice, so that the invoicing process requires no extra manual steps.
A business transitioning from paper or PDF invoices to electronic invoicing needs a simple way to get started with OIOUBL without changing their existing Business Central workflows.
As an accounts receivable clerk, I want to track whether electronic invoices have been successfully delivered, so that I can follow up on any failed transmissions.
A growing company that invoices both public and private customers in Denmark needs a cost-effective e-invoicing solution that scales with their invoice volume.

Key Concepts

OIOUBL: The Danish standard for electronic business documents, based on Universal Business Language (UBL). Required when invoicing the Danish public sector and widely used in private-sector B2B transactions in Denmark.
Sproom: A Danish e-invoicing service that receives, validates, and delivers OIOUBL documents to the recipient. Sproom handles the routing and delivery so you do not need to manage the technical infrastructure yourself.
Connection to Sproom: The app connects Business Central with Sproom via a secure FTP connection, so electronic documents are transferred automatically to Sproom for delivery.

The app includes several optional features that enhance the electronic document: Enable Attachments, Include Invoice as PDF, Payment Means (including Danish FIK), and Add Comment Lines.
