Cost Efficiency
Effective cost of acceptance — scheme fees, interchange, acquirer margin, gateway and ancillary charges — read against businesses with a comparable card mix, channel split and volume.
Why it matters
Acceptance cost is the only payment line that scales with every pound of revenue. Under blended pricing the components are invisible, so drift accumulates silently between contract reviews.
How businesses improve it
- Move from blended to interchange++ so interchange and margin are separately visible.
- Re-tender against your real card mix rather than a headline rate.
- Route debit and commercial cards on their correct interchange categories.
- Review ancillary line items — authorisation, PCI, statement and minimum-monthly fees.
Example indicators considered
- Effective blended rate across all channels
- Pricing model in use (blended, interchange++, fixed)
- Share of volume on debit versus credit and commercial cards
- Non-transactional fees as a share of total cost
- Months since the last commercial review
Outcomes of strong performance
- Acceptance cost at or below Renlow's modelled strong-performance reference
- Fee changes visible in the month they occur, not the quarter after
- Margin savings that hold as volume grows
