tl;dr
Payment fees are set up in Store Configurator → Costs as processing & method fee rates per payment provider.
They count as transaction costs, so they flow into your CM2.
Check them in the Revenue & Profit Flex Table by Payment Method.
If fees show 0, the payment method usually isn't configured yet — or a Store Update hasn't run since you added them.
Setup
To check your payment fees in Klar, they need to be set up properly in the Store Configurator in the Costs section — entering processing & method fee rates for your payment providers.
After adding or editing payment fees, trigger a Store Update (Store Configurator → Store Settings → Update Store Data) so the fees are recalculated into your reports. Allow about 30 minutes.
Analysis
To see the payment fees for a specific provider in a given time period, do the following:
Go to the Revenue & Profit Flex Table and open the Profitability tab.
Set the first dimension to Payment Method.
Set the second dimension to Order Name.
Now you can precisely see the calculated payment method fees for each payment method.
You can also remove the second dimension and switch to the Revenue tab to get a better overview of how often each payment method was used — and quickly spot if a specific payment method hasn't been configured yet.
Or drill down further by adding other dimensions.
Where do payment fees show up in my margins?
Payment fees are part of your transaction costs. In the Last Click P&L view they appear under Transaction %, and they're deducted in the contribution-margin waterfall: CM2 = Net Revenue − COGS − Logistics Costs − Transaction Costs. So incomplete payment-fee setup will overstate your CM2.
Why do payment fees show 0?
Work through these in order:
The payment method isn't configured. If a provider has no processing/method fee rate in Store Configurator → Costs, Klar can't calculate a fee and shows 0. Use the Revenue tab (dimension: Payment Method) to see which methods are missing.
No Store Update since the change. If you just added or edited the rates, trigger a Store Update and wait ~30 minutes — the fees don't recalculate on their own immediately.
If the rates are configured, a Store Update has run, and fees are still 0 after ~30 minutes, reach out to us.
