How zevOS compares — including where it loses
A comparison table where every column is green for one product is worth nothing to a buyer. Two rows below are honest disadvantages, and if either is a hard requirement for you, we would rather you knew now.
| Criterion | zevOS | Build your own | Global CSMS | Vendor software |
|---|---|---|---|---|
Hardware-agnostic across vendors Can you change charger brand without changing platform? | ||||
GST invoicing built in HSN/SAC, place of supply, sequential series — not a CSV your accountant reworks. | ||||
UPI as a first-class payment method With pre-authorisation and automatic partial refunds around it. | ||||
Charging without an app install QR to browser, priced before the driver commits. | ||||
Partner settlement with statements Contract-driven splits, session-level backing, scoped partner portal. | ||||
No subscription Fee applies to sessions that earned, not to a seat count or a tier. | ||||
OCPI roaming, both roles CPO and eMSP, so you can publish and consume. | ||||
Smart charging enforced on the charger TxDefaultProfile re-applied on boot, not a limit the platform hopes holds. | ||||
ISO 27001 / SOC 2 held today Some procurement processes require it as a gate. | ||||
ISO 15118 plug-and-charge Not yet built here. OCPP 2.0.1, the prerequisite, is supported. | ||||
Support in your timezone Someone reachable when a corridor site goes down on a Sunday evening. | ||||
Full data export, any time Sessions, meter values, payments, settlements — through the API, without asking. | ||||
Time to first paid session From installed hardware to money collected. |
- Yes, today
- Partly, or with work
- No
Reading the table
What the marks mean in practice
Comparison tables flatten things that are not flat. Three of these rows deserve more than a symbol.
Build your own is not free
Marked "yes" on flexibility, and correctly so. But an OCPP gateway, a payments and refunds engine, a tariff resolver, a settlement ledger and GST invoicing all have to exist before you sell a unit of energy. Teams underestimate the billing edge cases, not the protocol.
Global CSMS wins on certifications
If your procurement gate is ISO 27001 or SOC 2, that is a genuine advantage today and we are not going to argue it away. It typically comes with subscription pricing that lands before your utilisation does.
Vendor software is fastest to start
And that is real. The cost is that your platform choice is now welded to your hardware choice, which quietly removes your negotiating position on every future purchase order.
Bring the requirement you think disqualifies us
It is a better thirty minutes than a feature tour, and it saves both of us an evaluation cycle.
