About this skill
Swedish Invoice Compliance (Fakturering)
Critical: ML chapter renumbering
Invoicing rules moved from Chapter 11 (ML 1994:200) to Chapter 17 (ML 2023:200) on 1 July 2023. Every legacy reference to "ML 11 kap" maps to ML 17 kap in current law. Always cite ML (2023:200).

Quick decision trees
Is this invoice valid?
1. Has fakturadatum? → ML 17:24 p.1
2. Has unique löpnummer from a series? → ML 17:24 p.2
3. Seller's momsreg.nr (SE+10+01)? → ML 17:24 p.3
4. Buyer's momsreg.nr (if RC or intra-EU)? → ML 17:24 p.4
5. Full name+address, both parties? → ML 17:24 p.5
6. Description: quantity+nature of goods/svc? → ML 17:24 p.6
7. Delivery date (if ≠ invoice date)? → ML 17:24 p.7
8. Tax base per rate, unit price excl VAT? → ML 17:24 p.8
9. VAT rate stated (25/12/6%)? → ML 17:24 p.9

11. Special notations where required?
