Island.is Connector for Sales Documents

The Island.is Sales Connector automatically delivers posted sales invoices and credit memos to customers’ digital mailboxes on Island.is (Pósthólf). No manual steps after posting — the document is generated, sent, and tracked automatically.

How it works

1. A user posts a sales invoice or credit memo in Business Central
2. The connector checks whether sending is enabled and whether the customer is excluded
3. A PDF is generated using your configured Report Selections
4. The document is sent via CentaraIQ eDelivery to the Island.is API
5. The customer receives a notification in their Island.is Pósthólf
6. Document attachments from Business Central can be included

What gets delivered

Settings

Configure in Sales & Receivables Setup → Island.is Connector section:

• Foreign customers (no Island.is mailbox)
• Test accounts
• Customers with special delivery arrangements

Setup guide

1. Configure CentaraIQ connection

Before using this connector, Centara Base must be installed and configured.

Navigate to Centara Setup and configure:

• Web Service URL (provided by Centara)
• Client Certificate
• Island.is endpoint settings

Contact Centara support if you need credentials.

2. Install the connector

Navigate to Extension Management and install the Island.is Connector for Sales Documents.

After installation, assign the CTAISS All permission set to all users who need access.

3. Enable sending

Navigate to Sales & Receivables Setup → Island.is Connector section:

1. Check Sends Sales Invoices to Island.is
2. Optionally check Sends Sales Credit Memos to Island.is
3. Optionally check Sends Attachments to Island.is
4. Set the Receiver Type — typically Sell-to Customer No.

4. Review customers

Open each relevant Customer Card and verify:

• The customer number (No.) is a valid Icelandic kennitala
• Exclude from sending to Island.is is unchecked (unless the customer should be excluded)

5. Test

1. Create a test sales invoice for a customer with a valid kennitala
2. Post the invoice
3. Navigate to Centara Messages and confirm a message was created
4. Verify in the CentaraIQ portal that the delivery was processed
5. Check the customer’s Island.is Pósthólf (if you have test access)

Limitations

• Iceland only — designed for the Island.is digital mailbox
• Posted documents only — drafts are not sent
• Valid kennitala required — the customer number must be a valid Icelandic national ID
• Authorised senders only — your organisation must have Island.is Pósthólf access (municipalities, government agencies, law firms)
• No automatic retry — failed deliveries can be resubmitted manually from Centara Messages

Troubleshooting

Issue	Cause	Resolution
Invoice not sent after posting	Sending not enabled in Sales & Receivables Setup	Check the Island.is Connector settings
