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 — across multiple clients, in more than one currency. InvoiceSonic is the invoice app freelancers use to keep those jobs in one focused mobile app: invoice as soon as work is delivered, see what is still unpaid, and get paid without a payment processor taking a cut. Start with a free plan and no signup for the first invoice.
Project fees, retainers and hourly work · Free plan · Mobile and web · No cut of your payments
Built for independent work — Save each client once, show the scope clearly, credit deposits already paid and put a real payment date on every balance. The invoice creation takes a couple of minutes; the follow-up is automatic.
Enter the actual job details, review the totals and preview your invoice. You can start without an account. Downloads follow the free-tool limits; saving, tracked sending and reminders are available with an account.
Invoice a fixed milestone, day rate, tracked hours or a mix of deliverables and reimbursable costs. Each line item shows the client exactly what triggered the charge.
Record an upfront payment so the invoice explains the full project value and the exact balance remaining. Clients see one number to pay.
Unlimited clients with their own saved details, invoice history and payment status — the next invoice for any of them starts from the record, not from scratch.
Send a branded PDF that identifies the work, period, amount, due date and payment method. Create it on iPhone, iPad or in any browser, and it looks the same to the client either way.
Put bank transfer, PayID, Venmo, Zelle, Cash App or PayPal on the invoice. Clients who want to pay with credit cards use those apps; InvoiceSonic takes no percentage, which on a freelance income can be the difference of $1,000+ a year.
Set a weekly, monthly or custom schedule for clients who pay the same ongoing fee, and unlimited invoices on Pro so volume is never the limit.
Late payments strain freelance cash flow more than anything else. Schedule a polite follow-up so protecting the client relationship does not mean ignoring an overdue invoice.
Sole traders and small business owners who bill clients the same way — projects, hours, retainers — use the same invoice generation flow. Nothing here is freelancer-only; it is simply built for people who do the work and the billing.
No time tracking, project management tools or client portal. InvoiceSonic is the billing layer; it sits happily next to whatever you use to run the work.
Use the same project name, milestone, hourly period or retainer description the client approved, and the same invoice number sequence for every client.
Apply any deposit or discount, choose when it is due and include the bank or payment details the client needs.
Deliver the PDF immediately, then track the status and follow up from the same account — on your phone or at the desk.
Create the invoice now, add the way you want to be paid and send it while the work is fresh.
Create a freelancer invoiceIt should support fixed fees and hourly work, deposits, multiple clients with saved details, professional PDFs, clear deadlines, online payments and payment reminders for overdue invoices. Recurring invoices are especially useful for retainers. A user-friendly interface on a phone matters more than extra features you will not use.
