MSP Billing Software for Your Growing Service Portfolio
Your services have evolved. Give your billing the same room to grow.
ZOEY is MSP billing software that consolidates support contracts, Microsoft 365 and software licences, cloud services, security and telecoms onto one invoice. It combines recurring and usage-based billing with supplier cost visibility, an admin portal and a branded customer portal built in.
No more assembling the same invoices from separate spreadsheets every month, and no more licence changes slipping through the net.

Is Billing Holding Your MSP Back?
Managed service providers sell more services to more customers every year. Billing often struggles to keep up.
Spreadsheet Invoicing
Invoices rebuilt from spreadsheets and PSA exports every month.
Licence Changes Missed
Extra seats and mid-month changes that never reach the invoice.
Unclear Margins
No easy way to see which services actually earn their keep.
Telecoms as an Afterthought
Voice and connectivity billed separately from your IT services.
One Customer Invoice for Everything You Provide
Combine managed support, hosting, security, software licences and communications on one clear invoice. ZOEY shows every service and billing period clearly, so customers understand exactly what they are paying for.
Recurring charges can be billed monthly, quarterly or annually, in advance or arrears, with automatic prorating when services start, change or end mid-period.

MSP Billing Questions
Can ZOEY bill IT services and telecoms together?
Yes. ZOEY combines managed services, licences, cloud, security, voice and connectivity on one customer invoice.
Does ZOEY replace our PSA?
No. ZOEY works alongside your PSA. Our open APIs and Zapier listing let you connect the customer and service data billing needs.
How does ZOEY handle mid-month changes?
Recurring charges prorate automatically when services start, change or end during a billing period, so invoices stay accurate.
Can we see our margin by service?
Yes. Margin analysis and supplier reconciliation show which services, customers and suppliers earn their keep.
Can MSPs consolidate IT and telecoms billing in one platform?
Yes. ZOEY bills support contracts, Microsoft 365 and software licences, cloud services, security and telecoms together, so each customer receives one accurate invoice and you can see your margin by service.
How do we know we have outgrown our billing system?
Typical signs are invoices rebuilt from spreadsheets and PSA exports every month, licence changes that are missed or billed late, and no clear view of margin by customer or service. ZOEY is built to remove that manual work.
