## Overview

This section describes the Icelandic localization of Business Central. The overview page lists the available features: VAT reporting, electronic invoicing, IRS mapping and document deletion. It notes version 24.0.

Two pages stand on their own. One covers the legal requirement for issuing a single-copy invoice: when invoices are printed several times, a government report confirms ERP compliance, and the IRS Notification report prints the required legal statements. The other covers the Iceland W1 core app setup, which moves from the Icelandic localization to the W1 base app model, with features delivered as apps, starting from 24.0.

Two subtopics hold the detail. VAT covers printing VAT summary information and mapping chart of accounts entries to IRS tax numbers. General covers rules for deleting posted invoices and credit memos, exporting audit data, IRS number mapping, and registration number fields. Start with the overview page, then go to the subtopic that matches your task.

## Key points

- The overview page lists Icelandic features: VAT reporting, electronic invoicing, IRS mapping and document deletion.
- For single-copy invoices, printing an invoice several times requires a government report confirming ERP compliance.
- Sales & Receivables Setup has an electronic invoicing checkbox. It lets you print the IRS Notification report with the legal statements.
- The Iceland W1 core app setup applies from version 24.0 and delivers localization features as apps.
- Migration to the W1 base app model is a one-time manual data migration.
- VAT pages cover VAT summary information on sales and purchase documents.
- Chart of accounts entries can be mapped to IRS tax numbers for data files sent to the tax authorities.
- General pages cover deleting posted invoices and credit memos, exporting audit data, and registration number fields.
