For charge point operatorsWorks with your charging platform
Every session priced. Roaming costs matched. Margin per site, visible.
Billr takes session data from your charge point management system and your roaming partners, prices each session against the customer's or fleet's tariff, keeps the energy and roaming cost next to it, and hands finance invoice-ready lines.

AI assistant
Ask Billr anything. Through the AI you already use.
Copy one page from Billr into Claude, ChatGPT, Cursor or any assistant that can call an API. From then on it reads your customers, charges, price lists, bills and analytics directly, with the permissions of your own user.
- Investigate. Why did this invoice go up, which customers lose money, what did we charge this customer last year.
- Report. Margin per customer, product or service, as a table, a chart or a sentence, without an export.
- Prepare. Draft price lists, overrides and corrections. You review and publish in Billr.
- Nothing to install. The full data model is open through GraphQL, the analytics through REST. Your roles still apply.

Session in, priced line out. Cost included.
Billr sits next to your charging platform, prices every session against the right tariff, and shows you energy and roaming cost on each one.
Every session priced as it ends
Sessions arrive from your charge point management system as exports, API events or roaming CDRs. Billr prices each one by site, connector, energy, duration, idle time and the customer's contract within minutes, and shows you where the platform's price does not match your tariff.
Energy and roaming cost next to the price
Billr keeps what the session cost you in energy or in roaming fees and what you charged for it. Margin per site, contract and roaming partner, so you reprice before the next quarter instead of after it.
Fleet and business contracts with their own rules
Monthly minimums, volume tiers, dedicated connectors, a separate price for depot charging. Each contract is configured in Billr, not negotiated into the platform's tariff model.
Late and duplicate sessions handled before the invoice
A session sent twice is recorded once. A session without a matching tariff is flagged with the reason. Late roaming records are priced into the next period, and nothing reaches an invoice before you have seen the exceptions.
One invoice per fleet, one statement per roaming partner
Fleet customers get one monthly invoice across all sites and drivers. Each roaming partner gets one statement with every session listed, so disputes are settled before you send it, not after.
Every invoice comes with the session list
Each invoice carries a line-by-line report with every session, its price and its components. Fleet managers stop asking for session lists, and disputes get shorter.
What goes in, what comes out
Billr works from the session data your platform already records.
| Your systems send | Billr returns |
|---|---|
| A session: connector, kWh, start, end, customer or card | A priced line with energy, time and idle components, cost and margin |
| A roaming record from a partner | Priced at the partner's agreed tariff, partner cost recorded next to it |
| A new electricity price | Cost updated from that date, tariffs repriced by rule |
| A fleet contract with a monthly minimum | Minimum applied, overage priced, one invoice per fleet |
| A CDR priced by the platform | Re-rated against your tariff, the difference flagged |
| Month-end | Invoice lines per customer, fleet and roaming partner |

Controls
Built for finance teams that get audited.
Billing software is judged on the month it goes wrong. These are the rules Billr enforces so that month does not happen.
Recorded once, never billed twice
Send an event as often as you like. Billr stores it once under its ID, keeps its order or session reference, and it can only ever be billed once.
Billing waits for complete data
A run does not start until every data source has delivered up to the period end and no errors are waiting. Nothing goes out until you approve it.
Gap-free invoice numbering
Numbers are assigned when a bill is finalised, in sequence, one bill per customer, location and currency. No holes to explain to the auditor.
Corrections keep the history
A credit reverses the revenue, with or without the cost. A corrected event credits the old charges and bills new ones. The originals stay.
Re-price with a preview
After a price change, see the difference per customer for a selection or a whole period before anything is applied.
Who changed what, and when
Field-level history on prices, price lists, mappings and overrides, plus who started and who approved every billing run.
Every customer runs in its own environment in the EU (AWS Ireland), with its own database, its own users and invite-only access.
Questions we hear first
Do we have to replace our charge point management system?
No. It keeps running the chargers and the sessions. Billr reads the session data from it and prices it against the contracts.
Which data does Billr need?
Session records with connector, energy, start and end time and the identifier of the customer, card or fleet, from your platform's export, API or roaming records.
Can Billr bill roaming partners too?
Yes. Sessions from roaming drivers are priced at the partner's agreed tariff and invoiced to the partner, with your own cost next to them.
How long does it take to go live?
About four weeks. Week one we map your tariffs and a month of sessions, weeks two and three we configure and run Billr next to your current billing, week four you invoice real customers with it.
Who changes tariffs once we are live?
Your team, in Billr, from a date you choose, per site, per contract or for everyone at once.
The first step
Your month in Billr. Free.
You do not need a project, a budget or a decision to find out what Billr would change for you. You need half an hour.
30 minutes, your case
You show us how you bill today: your systems, your price lists, where the month goes wrong. We tell you on the call what Billr would do with it, and what it would not.
Your real data in Billr
One customer, one month: send us the invoice and the data behind it. You get it back priced in Billr, matched against your invoice, with the breakdown behind every line and the analytics on top: volumes, revenue, margin.
Something you can forward
A short document: what matched, what differed and why, what we found in the numbers, and what a setup would involve. No contract, nothing to install, nothing to prepare.
If you do not like what you see, you say no. That is the whole risk.
