Subscription Billing Software That Keeps Up With Your Business
Recurring revenue should create opportunity, not more invoice admin.
ZOEY brings recurring charges, subscription changes and one-off fees into one billing platform. Give your team an admin portal to manage the detail and your customers a branded portal to see their bills, both built in.
From software and hosting to maintenance and managed services, ZOEY keeps every plan, change and part-period charge accurate.

Automatic Prorating
Part-Period Charges
Card and Direct Debit Payments
Has Your Subscription Model Outgrown Your Billing?
Plans change, customers upgrade and usage varies. Here is where billing starts to struggle.
Mid-Cycle Changes
Upgrades and downgrades recalculated by hand every month.
Invoice Sprawl
Several subscriptions per customer, each on a separate invoice.
Usage Outside Billing
Part-period charges calculated in spreadsheets, then added manually.
Payments Chased by Hand
Collections reconciled manually against invoices each month.
Your Pricing Changes. Your Billing Follows.
A new subscription. An extra service. A change halfway through the month. ZOEY keeps the service record and the charge schedule connected, so your team can manage every change without a separate spreadsheet for each customer.
Configured prorating applies automatically when services start, change or end between billing dates, with the service dates and charging rule behind every adjustment.
- Monthly, quarterly and annual schedules
- Billing in advance or in arrears
- Automatic part-period prorating
- Time-limited promotions and discounts

One Clear Bill
