    About This Skill

    What it does

    This skill automates the end-to-end process of preparing and filing the Periodisk sammanställning (PS) to the Swedish Tax Agency (Skatteverket). It handles reporting for EU sales of both goods and services, ensuring compliance for ABs and sole traders (enskild firma).

    How it works

    The agent can retrieve financial data from three sources: web-based accounting software (like Fortnox, Bokio, or Visma), local accounting folders on your machine, or manual input provided by you. It specifically monitors accounts such as 3308 (EU services) and 3106 (EU goods), validates customer VAT numbers via the official EU VIES service, and calculates totals per customer.

    The skill guides you through the Skatteverket e-service login, populates the complex multi-row forms accurately using specialized UI interaction methods, and generates a professional PDF background report for your archives.

    Supported tools

    • Accounting: Fortnox, Bokio, Visma eEkonomi, and generic ledger exports.
    • Validation: Direct integration with EU VIES for VAT verification.
    • Reporting: Automatic PDF and TXT report generation for audit trails.
    • Filing: Direct interaction with Skatteverket's 'Periodisk sammanställning' e-service.

    Why use this skill?

    Manual filing is error-prone, requiring rounding to whole SEK and specific transaction codes (S, T, or blank). This skill eliminates manual data entry, prevents "timeout" frustrations during filing, and ensures your records perfectly match what was submitted, saving you from a 1,250 SEK late fee.

    Saves confirmation PDF for you

    After submission, it automatically downloads the official receipt PDF from Skatteverket using a reliable JavaScript-based method and saves it alongside text backups in your bookkeeping folder.

    Use Cases

    • Identify EU sales in Fortnox/Bokio and map them to correct VAT codes.
    • Validate all EU customer VAT numbers against the official VIES database.
    • Automate the multi-step filing process on the Skatteverket e-service portal.
    • Generate reconciliation reports and save official submission receipts locally.
    • Handle quarterly or monthly reporting deadlines and prevent late fees.

    The skill connects to Swedish Tax Authority (Skatteverket) via Chrome browser to fill in and submit the EC Sales List form (Periodisk Sammanställning in Swedish). It also fetches the receipt PDF via JavaScript. Requires BankID authentication by the user. Reads local bookkeeping files (PDF invoices, text files) and generates report PDFs using fpdf2. This skill can be adapted to the tax authorities in your own country, but it will require some training of the skill.
