ZOEY Rate: A High-Volume Rating Engine for Your Billing Ecosystem
You have the front end. We bring the rating expertise.
Keep the CRM, customer portals and invoice presentation you have already built. ZOEY Rate collects, mediates and rates many millions of usage records against your charging rules, then returns rated data straight to your systems.
It is the same rating capability that powers ZOEY, delivered as a dedicated service for businesses operating at scale.






Built for High Volumes
Mediation and Rating
Your Charging Rules
Rated Data Returned
Is Usage Rating the Weak Link in Your Stack?
Many platforms handle accounts and subscriptions well, then struggle with the usage in between.
Volumes Outgrowing You
Usage volumes your current platform struggles to process on time, every month.
Hard-Coded Tariffs
Pricing changes that need developer time instead of a simple rate card update.
Records That Can’t Be Rated
Exceptions discovered after invoicing, when the revenue has already been lost.
A Front End You Want to Keep
A CRM and portals that work well for you, with rating that simply doesn’t.
From Usage Record to Rated Output
ZOEY Rate sits between your usage sources and your own billing systems, with checks at every stage.
01
Collect
Source records from 400+ supported providers are collected automatically, including files delivered by SFTP and API.
02
Mediate
Fields are parsed and validated, customers and services identified, and supplier classifications mapped.
03
Rate
Usage is rated against your rate cards, time bands, allowances and destination rules, by the unit you set.
04
Deliver
Rated data is returned to your systems in an agreed format, ready for your own invoicing and portals.
More Than One Way to Use ZOEY Rate
The architecture separates usage processing from presentation, so ZOEY Rate fits a wide range of businesses.
Communications Providers
Add specialist CDR mediation and voice rating behind your existing CRM, OSS/BSS and customer portals, keeping the experience your customers know.
Resellers and Wholesale
Rate usage where upstream records and downstream charges follow different commercial rules, with the service identifiers and output you need.
Mobile, Data and IoT
Bring the usage formats and allowance models behind mobile, connectivity and IoT services, with the feed, units and rules agreed up front.
Metered Subscriptions
Turn consumption into charges when your platform handles recurring fees well but struggles to price the usage in between.
Rate Cards That Follow Your Commercial Model
Separate the rules you use to charge customers from the information your suppliers send. Maintain multiple rate cards with effective dates, and configure the detail your propositions need.
Your retail proposition never has to be a copy of a supplier’s price list.
- Peak, off-peak, weekend and flat-rate time bands
- Connection fees, initial periods and follow-on rates
- Per-second and per-minute charging and rounding
- Allowances with cycle resets, prorating and overage
- On-net, calling-circle and special-number rules

Exceptions Resolved Before They Become Missing Charges
Records that cannot be rated because service, tariff or date information is incomplete are identified straight away, not discovered after the invoice has gone out.
Every record is accounted for, so the usage you process is the usage you bill.
Exception Handling
Unratable records are flagged with the reason, ready for correction and reprocessing.
Controlled Reprocessing
Corrected configuration is applied through an agreed reprocessing workflow.
Spend Threshold Events
Where configured, spend thresholds from processed usage are passed to your systems.
Detailed Rated Output
Customer and service references, usage detail and pre- and post-allowance charges.

Work With People Who Understand Rating
Tekton Billing combines development expertise with practical billing knowledge. We work through representative records and awkward edge cases with your team and validate the output against your expected charges.
Operating responsibilities are agreed before you go live, so everyone knows exactly who does what.
ZOEY Rate Questions
Do we need to replace our portals or CRM?
No. ZOEY Rate is designed around agreed inputs and outputs, so you keep your existing front end and invoicing.
How much usage can ZOEY Rate handle?
ZOEY Rate mediates and rates many millions of usage records for its partners. We size the service around your volumes and processing schedules.
Can it rate non-voice usage?
We review the source format, charging unit and pricing rules for each service. Data, messaging and other event types are confirmed as part of the implementation.
