Stop Sending Invoices Manually
At a certain scale, manual billing stops being inefficient and starts being dangerous. Missed charges, billing disputes, and compliance gaps cost real money. ZeyOS automates the entire cycle - from contract to paid invoice.
Invoices That Send Themselves
Define billing schedules once. ZeyOS generates and sends on due dates - monthly, quarterly, or annually - for every active subscription.
Audit-Proof by Default
Every transaction is immutably recorded. No manual corrections, no reconciliation gaps. Full compliance trail ready for your auditors.
API-Driven Billing Logic
Build custom billing workflows on top of the ZeyOS REST API. Usage-based billing, dynamic pricing, external triggers - all possible.
Recurring Billing That Runs Without You
The moment you have more subscription customers than you can manually track, billing becomes a liability. ZeyOS removes the human dependency from your billing cycle entirely.
Any Billing Frequency Monthly, quarterly, annual, or fully custom intervals - per customer, per contract, per product line.
Auto-Generated Invoices ZeyOS creates branded, compliant invoices automatically on due dates and sends them to the right billing contact - no human in the loop.
Auto-Renewal Management Contracts renew automatically on their anniversary unless cancelled. Proactive renewal alerts keep your sales team informed and customers retained.
Proration on Changes Mid-cycle upgrades, downgrades, or seat changes calculate automatically. No manual adjustments, no billing disputes.
Billing Models as Complex as Your Contracts Require
One-size billing rarely fits real business. ZeyOS supports any pricing structure - flat rate, seat-based, usage tiers, volume discounts, multi-currency - and applies them automatically at invoice generation.
Seat-Based & Usage Billing Track seat counts or usage metrics per customer and bill accurately based on actual consumption - not estimates.
Multi-Currency Support Invoice in the customer's local currency with automatic exchange rate handling. Reduce friction for international clients.
Tiered Volume Pricing Define pricing tiers that apply automatically based on quantity or usage - no manual intervention at billing time.
Compliance Built Into Every Transaction
Billing compliance isn't just about sending the right invoice - it's about maintaining an immutable record of every financial event. ZeyOS makes this automatic.
Immutable Transaction Records Once a transaction is booked, it cannot be altered - only offset by a credit note. Full audit trail automatically maintained.
Branded PDF Invoices Every invoice generated matches your corporate identity exactly - logo, colors, layout, payment terms. Pixel-perfect, every time.
Credit Note Management Issue refunds or corrections as proper credit notes linked to the original transaction. Clean books, always.
IT Managed Services, 150+ subscription customers
We were sending invoices manually every month - it took two days of finance time, and we still missed charges. After switching to ZeyOS, the billing cycle runs automatically. Our first fully automated month had zero errors and took zero finance hours.
