Mobile Billing Software for Business Mobile Resellers
Build your mobile proposition around your customers.
ZOEY brings SIM rentals, supplier usage and your own tariffs and bundles together in one platform, with a branded customer portal that puts real-time service controls in your customers’ hands.
From your first connections to a large multi-network base, ZOEY keeps every SIM billed correctly and every customer in control of their spend.






Real-Time SIM Swaps
Instant Bars
Spend Caps and Alerts
Shared and Pooled Bundles
Is Mobile Billing Costing You More Than It Should?
Mobile customers expect instant answers and instant changes. Here is where legacy billing lets resellers down.
Bill Shock Disputes
Unexpected roaming and data charges leading to credits and churn.
Tickets for Every Change
SIM swaps and bars that need a call to the network every time.
Bundles That Don’t Fit
Allowances tied to your supplier’s structure rather than your own.
Unbilled Wholesale Costs
Wholesale charges that don’t match the SIMs you actually bill.
Your Whole Mobile Estate in One Billing Process
Organise every SIM, tariff and bundle for every customer in ZOEY. Usage is loaded automatically from supported providers and rated against your own allowances, so overage is calculated correctly without spreadsheets.
Many customers buy more than mobile. Combine mobile charges with fixed line, connectivity, managed IT or other subscriptions on the same invoice.
- SIM rentals, usage and bolt-ons on one invoice
- Individual, shared and pooled allowances
- Self-optimising bundles with automatic renewal
- Mobile alongside fixed, IT and subscription services

Real-Time Self-Service Under Your Brand
Through enhanced integrations with leading wholesale mobile providers, your customers can swap SIMs, apply bars and set spend caps in real time from your branded portal, without a single support ticket.
Available actions depend on each provider connection, and we confirm them for your supplier mix during set-up.
SIM Swaps
Lost or damaged SIMs replaced in real time from the customer portal.
Bars on Demand
International, premium-rate and data bars applied and lifted instantly.
Spend Caps
Multi-stage alerts by cost, percentage or time, with optional barring.
Usage Analytics
Near real-time unbilled usage by user, department and cost centre.
Built for Mobile Resellers and Service Providers
Every mobile billing feature is included as standard, with no chargeable add-ons.
Hourly Usage Loading
Mobile usage collected automatically from supported providers and processed hourly, so alerts and bars act on current data.
Wholesale Cost Checks
Supplier reconciliation and margin analysis highlight SIMs you pay for but don’t bill, and tariffs that lose money.
Direct Network Provisioning
ZOEY SP adds direct O2 and Vodafone provisioning for mobile service providers, from connections to porting and bars.
