What to do

  1. Only new prices use this default. Check the currency before entering amounts.
  2. Check legal names, addresses and declared organisation numbers. Nine digits with MOD11; VAT: NO + the same nine digits + MVA. Syntax and checksum only; no registration, identity or legal-form verification.
  3. I checked both legal names, legal addresses, registry numbers and VAT IDs. These are declarations, not online verification.
  4. Seller is a private Norwegian VAT-registered AS; buyer is a private Norwegian VAT-registered business. Completed domestic service only.
  5. Ordinary VAT accounting; no exemption, reverse charge, VAT group or special scheme.
  6. Only ordinary repair or maintenance labour on computers or electronic equipment at 25%. No bicycle, shoe, leather goods, clothing or household linen repairs; no property work, healthcare, ships or aircraft.
  7. No goods, parts or materials are supplied or used.
  8. One completed service; no payments received, advances, cash accounting, discounts or prior adjustments.
  9. English document only: I checked that the service descriptions and other content are understandable in English. Names remain unchanged.

Before you continue

Invoice currency comes from every approved source line. Mixed currencies require separate, correctly approved sources. The payment currency must match. NOK/NOK and SEK/SEK need no exchange rate or EUR accounting declaration.

Local test: invoice and service on the same day. NOK needs no exchange rate; an explicitly priced EUR invoice uses the reviewed EUR/NOK fixture. This is a test boundary, not a statutory deadline.

Later agreed reduction of the original domestic labour charge. Currency, VAT rate, original invoice and remaining amount stay bound. This is an agreed price reduction, not a replacement invoice or a return of goods.

EUR / NOK: Choose the fixture for the service day and enter the invoice timestamp inside its displayed publication window. EUR remains the invoice currency; only the taxable base and VAT are converted to NOK. No real rate is downloaded or verified. Available test dates: 2026-01-01, 2026-03-29, 2026-08-02 and 2026-10-10. Other dates have no fixture. I checked the synthetic fixture, rate direction, date and publication window. The frozen source and rounded NOK amounts are test data, not an official exchange rate.
