Manage Client Billing at Scale
InvoiceStream is built for agencies managing hundreds of clients and projects. Unlimited companies, approval workflows, billable hours tracking, and multi-currency support.
Billing at Scale is Hard
Especially when you're managing hundreds of clients across multiple time zones.
Managing Hundreds of Clients & Projects
Agencies work with dozens of clients simultaneously. Tracking who owes what, across multiple projects, becomes impossible.
Billable Hours and Expenses Are Scattered
Time tracking, expenses, and project costs are spread across different tools. Creating invoices becomes a manual data-gathering nightmare.
Multi-Currency Complexity
International clients with different currencies and payment methods require custom handling for each invoice.
No Approval Workflows
Junior team members create invoices, but there's no way to review, approve, and prevent billing mistakes before sending.
