What counts as MRR?

Only recurring revenue, billed predictably.

MRR (Monthly Recurring Revenue) is your recurring subscription revenue per month, billed through Kontorion. Each plan includes an MRR volume at a fixed monthly flat rate. Above that, a transparent revenue share applies.

  • Starter: up to €15k MRR included in the flat rate, then 0.8% revenue share.
  • Scale: up to €80k MRR included in the flat rate, then 0.5% revenue share.
  • Enterprise: unlimited MRR at a flat rate, no revenue share.

The revenue share is calculated only on the MRR above the included threshold, not on your entire revenue.
