Built for Agencies.Billed to Protect Your Cash Flow.
AI-powered invoicing for agencies managing multiple clients, retainer agreements, and project-based billing. Create invoices in bulk, track payments in real time, and automate payment follow-ups — so your cash flow stays healthy while you focus on delivering great work.
Running an agency means running on billing friction
If you manage multiple clients, you know that invoicing complexity compounds fast. These are the problems that slow down every growing agency.
Too many clients, too many spreadsheets
Managing invoicing across 10, 20, or 50 client accounts in spreadsheets is a full-time job. Every month you spend more time billing than growing the agency.
Retainers, milestones, and hybrid billing are messy
When you have a mix of retainer clients, milestone-based projects, and hourly work, no simple invoice template handles it cleanly. You end up with inconsistent, error-prone billing.
Clients dispute invoices over scope
Without a clear link between contracts, project scope, and invoices, clients question every charge. You spend hours resolving billing disputes instead of doing the work.
International clients mean currency headaches
Billing US clients in USD, EU clients in EUR, and UK clients in GBP — with correct tax treatment for each — adds serious complexity to every invoice.
Create Multiple Client Invoices in Minutes
Generate invoices for 20 clients in the time it used to take you to invoice one. Eonebill's AI invoice generator handles the repetitive work — client names, project descriptions, rates — so you can batch process your entire monthly billing in one session.
Track Multiple Projects and Clients in One Place
Eonebill's client dashboard gives you a real-time view of every active project, outstanding invoice, and payment status across your entire agency. Know exactly who owes what, when it's due, and who's overdue — at a glance.
Retainer Clients, Managed Automatically
Set up monthly retainer agreements with automatic usage tracking. Eonebill monitors hours against the retainer cap for each client, alerts you as you approach the limit, and generates invoices on your schedule — monthly, bi-weekly, or custom.
Get Paid Faster with Automated Reminders
Late payments kill agency cash flow. Eonebill's automated reminder sequence — sent before the due date, on the due date, and for overdue invoices — keeps payments moving without you having to send awkward follow-up emails.
