Invoice software for consultants

Bill hours, projects, or retainers in clean, professional invoices. Multi-currency for international clients. Payment tracking that tells you who actually paid the deposit.

The problems you actually have

Hourly tracking that scatters everywhere

Your hours live in a notes app, a timer, a calendar, and your head. Reconstructing them at month-end is painful.

Mixed billing models

One client is hourly, another is project-based, a third is on retainer. Your invoicing tool needs to handle all three cleanly.

International payments

You bill in USD for one client and EUR for another. Most simple tools force you to pick one.

Deposit & milestone billing

Tracking deposits, milestone payments, and final invoices for the same engagement is its own little project.

Questions, answered

Can I bill by the hour and by the project on the same invoice?+

Yes. Each invoice line is independent — mix hourly time, fixed fees, and expense reimbursements freely.

Do you support recurring retainer invoices?+

Recurring billing is on the roadmap. For now, retainers can be sent manually each month from a saved template.

Which currencies are supported?+

All major currencies (USD, EUR, GBP, etc.). You can bill different clients in different currencies and your dashboard reports show consolidated revenue.

Can clients pay directly from the invoice?+

Invoices include your payment instructions. Stripe-based online payment is on the roadmap; for now, clients pay via bank transfer using the details on the invoice.
