The short version

  • Only Fortnox has a free tier, so it costs nothing to try first.
  • Each has a real cost: Fortnox corporate packages alone span at least 7 named tiers (Mini through Stor+) priced from 209 kr/man to 919 kr/man, and add-on programs are billed separately per module (SEK); Soldo cards are prepaid, so if the central wallet runs low the cards decline in front of a supplier, and treasury has to keep an idle float funded rather than using a credit line.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Fortnox

  • Corporate packages alone span at least 7 named tiers (Mini through Stor+) priced from 209 kr/man to 919 kr/man, and add-on programs are billed separately per module (SEK)
  • The Fortnox Access verification tier is priced by transaction volume, rising from 9 kr/man at zero verifications to 199 kr/man at 1000+ verifications (SEK), so cost is not fixed and scales with usage

Soldo

  • Cards are prepaid, so if the central wallet runs low the cards decline in front of a supplier, and treasury has to keep an idle float funded rather than using a credit line.
  • The plan fee covers only three users, and per-user charges plus physical card fees mean the real monthly cost is several times the advertised headline for a team of twenty.
  • It does not extend credit, so it gives no working capital benefit and no card rewards of the kind US charge card issuers use to offset their cost.
  • Sole traders and some business types are not accepted, which catches out small consultancies expecting to sign up online.
  • Coverage is European; a company with US or Asian subsidiaries will need a second card programme and a second expense workflow for them.
