You see every price.
Including the ones we did not set.
When someone charges at your site with an external card, their mobility provider sets the price — not you and not ENIO. The only question is whether you get to see it. At ENIO it appears per transaction in the backend, together with the discount fee and the amount that reaches you. For larger customers we deliberately do not offer guaranteed fixed prices.
Guaranteed price versus actual price
A guaranteed amount per kWh sounds like certainty and costs you twice. First, an operator promising you a fixed amount locks out every provider whose price falls below it — their customers charge elsewhere and that revenue never happens. Second, with high-price cards the operator keeps the difference between what was really paid and your fixed amount. Set your case:
| Card / mobility provider | Price the provider charges | kWh per month | ENIO — actual price minus discount | Guaranteed-price model |
|---|---|---|---|---|
| Low-price providerMobility card with a large customer base | 0.39 € | — | — | — |
| Mid-price providerthe most common roaming case | 0.59 € | — | — | — |
| High-price providerFleet card or premium tariff | 0.79 € | — | — | — |

Discount 10 % · Minimum price 0.5 €/kWh · Guaranteed-price model 0.45 €/kWh
What transparency actually delivers
More revenue
Because there is no minimum price, every card can charge — including the cheap one from a provider with a very large customer base. Each of those sessions is revenue an operator with a fixed-price guarantee never lets happen in the first place.
- No locked-out mobility providers
- Higher utilisation per charge point
Higher contribution margin
If a provider charges 79 cents, you receive 79 cents less the agreed discount fee — not the fixed amount settled on once. With high-price cards the margin stays with you rather than the operator.
- Provider price visible per transaction
- The discount fee as the only deduction
Billing you can check
Roaming, your own cards, app payments and the debit and credit card revenue from the payment station all appear in one list. Your finance team has nothing to piece together and nothing to take on trust.
- Automated CSV and PDF export
- REST API into your own system
One line item instead of many small ones
The discount fee is the share ENIO keeps from the net amount billed — typically eight to nine percent, or four cents per kWh. It covers the roaming connection, invoicing, fiscalised receipts, receivables, cash management and support for drivers. If you take parts of that on yourself, you pay less. There is no second, hidden margin behind it.
- One percentage, written into the contract
- Shown per transaction, not as a lump sum
- Falls when you take on tasks yourself
- Partners receive a quarter of it for referred leads
Transparency and the discount fee
What is a discount fee in charging billing?
The discount fee is the percentage a billing provider keeps from the net amount of a charging session. At ENIO it is typically eight to nine percent, or alternatively four cents per kWh, and it covers roaming, invoicing, receipts, receivables and cash management, and driver support. It is shown per transaction.
Why does ENIO not work with guaranteed prices for larger customers?
Because a guaranteed price has two drawbacks the customer never sees. First, mobility providers whose negotiated price sits below the guarantee have to be locked out — their customers then charge elsewhere. Second, with high-price providers a gap opens between what was actually paid and the guarantee, and that gap stays with the operator. ENIO instead passes on the price actually charged, less the discount fee.
Do I see debit and credit card revenue individually?
Yes. Revenue from the ENIO payment station appears in the same backend and the same list as roaming and card revenue — per transaction with date, site, kWh, amount and payout. There is no separate statement from the terminal operator that you would have to reconcile.
What happens if a mobility provider pays very little?
The session still happens and you see the low price openly in the backend. That is economically better than the alternative: a blocked provider brings in nothing at all. If a provider stays too low over time, ENIO renegotiates or, in agreement with you, removes them — but as a decision, not as an invisible rule.
Can I pull the billing data into my own system?
Yes. All data is available as a CSV and PDF export, automated through the report planner on a date you choose, and additionally through the REST API. ENIO is built API-first: the interface uses the same endpoints you get for your own live dashboards.
