ISP Billing Software for Connectivity Providers
Grow your connectivity portfolio without outgrowing your billing.
ZOEY combines recurring connectivity charges, usage and additional services on clear customer invoices, with an admin portal for your team and a branded customer portal for your customers built in.
Installations, upgrades, cancellations and add-ons are billed accurately, with prorating applied automatically, so every invoice is right first time.

Is Your Billing Slowing Your Growth?
Connectivity providers add customers, products and suppliers quickly. Billing needs to keep up.
Mid-Month Changes
Upgrades and cancellations recalculated by hand every billing period.
Separate Invoices
Connectivity, voice and hardware billed on different invoices.
Missed Renewals
Contract end dates buried, with renewals and fees easy to miss.
Supplier Cost Gaps
Wholesale circuits you pay for that aren’t matched to billing.
Bring Your Connectivity Portfolio Together
Combine broadband, fibre, leased lines, hosted voice, hardware, hosting and support on the same customer invoice. ZOEY organises the service information and billing periods so every customer understands their account.
Where your services include usage, ZOEY rates it against your own pricing rules and combines it with recurring charges, rather than leaving it in a separate calculation.
- Recurring connectivity and voice services
- Installation, hardware and one-off charges
- Usage rated against your own pricing
- Multi-brand invoicing for partners

Built for the Way ISPs Bill
Every feature is included as standard, with no chargeable add-ons.
Changes During the Period
Service starts, upgrades and cancellations prorate automatically, so charges are reviewed before the invoice run, not after.
Contracts and Renewals
Contract end dates, renewals and pro-rated early termination fees tracked and calculated for you, at no extra cost.
Margins and Supplier Costs
Supplier reconciliation and margin analysis highlight circuits and services that need attention before they cost you more.
Integration Requirements Agreed Up Front
Every ISP has a different mix of suppliers, accounting, payment and provisioning systems. We talk through yours at the start, confirm which connections are available and agree any additional work before you commit.
That means no surprises, and a billing platform that fits the way your business already works.
Supplier Data
Usage and charges from 400+ supported providers, with new ones built free.
Open APIs
Connect ZOEY to your CRM, provisioning and service systems.
Payments
Stripe, GoCardless and other card and Direct Debit providers.
Accounting
Invoice and ledger exports ready for Xero, Sage, QuickBooks and more.
