VAT, payments & the rest.
The remaining cost layers that complete the picture: tax, payment fees, platform fees, and any costs unique to your business.
VAT & tax
Configure VAT per region. CM6 applies it at the line-item level so net revenue is genuinely net, not gross with tax quietly inflating your margin.
Payment fees
Per-gateway rates applied per transaction, including FX conversion and chargeback handling. CM6 ships with the common schedules:
Shopify Payments
PayPal
Klarna
Using a gateway not listed? Let us know and we'll add its schedule.
Platform & subscription fees
Your Shopify subscription and GMV-based fees are real costs of trading. CM6 allocates them across orders rather than treating them as invisible overhead, so each order carries its fair share.
Custom costs
Every business has costs the standard layers don't capture: influencer fees, packaging inserts, a per-order levy, a fixed monthly cost to amortize. Add them as custom costs and CM6 folds them into contribution profit alongside everything else.
Common issues
| Symptom | Fix |
|---|---|
| VAT shows as zero on some orders | No usable VAT rate was available for that order; configure the region's rate so it's applied. |
| Payment fees look wrong | Check the gateway is mapped to the right fee schedule; rates differ by gateway and region. |
| A known cost isn't reflected | Add it as a custom cost. Standard layers won't capture business-specific costs. |
