| ## Swedish accounting considerations |
|
|
| ### VAT/Moms handling |
|
|
| - Midday tracks VAT amounts when available |
| - Maps to appropriate Fortnox VAT codes |
| - Review VAT settings in your Fortnox configuration |
|
|
| ### BAS account structure |
|
|
| Fortnox uses the Swedish BAS standard: |
|
|
| - **1xxx**: Assets |
| - **2xxx**: Liabilities and equity |
| - **3xxx**: Revenue |
| - **4xxx**: Cost of goods sold |
| - **5-6xxx**: Operating expenses |
| - **7xxx**: Depreciation and financial items |
| - **8xxx**: Financial income/expenses |
|
|
| Midday's category structure aligns with this for straightforward mapping. |
|
|
| ### Fiscal year |
|
|
| Ensure your fiscal year settings match between Midday and Fortnox for accurate reporting. |
|
|
| ## Troubleshooting |
|
|
| ### Export errors |
|
|
| If transactions fail to export: |
|
|
| - Check that the Fortnox connection is active in [Apps](https://app.midday.ai/apps) |
| - Verify transactions are categorized (uncategorized transactions can't export) |
| - Check category mappings are complete |
|
|
| ### Mapping errors |
|
|
| If transactions appear in the wrong account: |
|
|
| 1. Review category mappings in Fortnox settings |

| 3. Export again |
|
