Invoice App for Freelancers

Bill the project while the value is still obvious.

Freelance invoices rarely follow one pattern. One client pays a deposit, another is billed by the hour, and a retainer needs the same invoice every month. InvoiceSonic keeps those jobs in one focused app so you can invoice as soon as work is delivered and see what is still unpaid.

Project fees, retainers and hourly work · Free to start · Mobile and web

Built for independent work — Save each client once, show the scope clearly, credit deposits already paid and put a real due date on every balance.

What you get

Project and hourly billing

Invoice a fixed milestone, day rate, tracked hours or a mix of services and reimbursable costs.

Deposits shown clearly

Record an upfront payment so the invoice explains the full project value and the exact balance remaining.

Professional client delivery

Send a branded PDF that identifies the work, period, amount, due date and payment method without an awkward homemade spreadsheet.

Recurring retainers

Set a weekly, monthly or custom schedule for clients who pay the same ongoing fee.

Payment visibility

Keep sent, viewed, due and overdue invoices together instead of searching email threads and download folders.

Automatic reminders

Schedule a polite follow-up so protecting the client relationship does not mean ignoring an overdue balance.

  3. 3

    Send and monitor

    Deliver the PDF immediately, then track the status and follow up from the same account.

Frequently asked questions

What should a freelancer invoice app include?

It should support fixed fees and hourly work, deposits, saved clients, professional PDFs, due dates, payment instructions and overdue follow-up. Recurring invoices are especially useful for retainers.

Can freelancers create invoices without a company?

Yes. A freelancer can generally invoice under their own legal name or registered business name. Include the tax or business identifiers required where you operate, and check local registration rules.

Can I invoice a monthly retainer automatically?

Yes. InvoiceSonic Pro can create and send recurring invoices on a weekly, fortnightly, monthly or custom schedule.

Does the app support deposits?

Yes. Show the agreed project total and credit the deposit already received so the client sees a clear remaining balance.

Is there a free plan for freelancers?

Yes. You can create and download the first invoice without signup, and the free plan covers up to three invoices per month. Upgrade when you need a larger saved and automated workflow.
