Freelancers need invoicing software that gets out of the way. A useful tool should create a professional document quickly, remember repeat clients, support the way you charge, and make overdue work visible without turning billing into a second job.
We compared seven options for project and hourly billing, recurring retainers, expenses, reminders, payment collection, multi-currency work, and price. Product details were checked in September 2026.
Disclosure: InvoiceSonic is our product. It is ranked first for freelancers who want a focused, low-friction invoicing workflow. We also call out cases where another product is the better choice.

1. InvoiceSonic — best invoicing software for most freelancers
InvoiceSonic's freelancer invoicing software starts with a no-signup generator, so a new freelancer can create a client-ready PDF before choosing a subscription.
The invoice form includes itemized services, quantity or hours, rates, discount, tax, payment instructions, due date, and notes. Paid workflows add saved clients, reusable business details, branding, recurring invoices, sending, open tracking, and analytics.
Best for: designers, developers, writers, marketers, consultants, tutors, and independent contractors who want invoicing without full accounting software.
Why it ranks first: the free starting point is genuinely quick, while the paid product covers the repeat tasks that appear as a freelance business grows.
Not ideal for: freelancers who need proposals, contracts, tasks, time tracking, and accounting inside a single suite.
2. FreshBooks — best for hourly freelancers
FreshBooks lets freelancers track time and expenses, then move that information into invoices. Estimates, proposals, retainers, deposits, recurring invoices, reminders, online payments, and reports are also available.
Best for: consultants and creatives who bill by the hour or pass project expenses to clients.
Why choose it: fewer gaps between doing the work, recording it, and billing for it.
Trade-off: ongoing subscription cost and limits that vary by plan.
3. Zoho Invoice — best free freelancer automation
Zoho Invoice includes recurring invoices, reminders, time tracking, expenses, multi-currency transactions, customizable templates, reports, and a customer portal.
Best for: cost-conscious freelancers who want a structured account and are comfortable configuring it.
Why choose it: its free feature set goes well beyond basic PDF generation.
Trade-off: more menus and setup than a freelancer sending a few simple invoices may want.
4. Wave — best for freelance bookkeeping
Wave combines invoicing with bookkeeping records and optional online payments. Its free Starter plan supports unlimited invoices and estimates, while Pro adds automation such as late-payment reminders and bank transaction tools.
Best for: North American freelancers who want a basic financial dashboard alongside invoicing.
Why choose it: invoices and bookkeeping can share the same records.
Trade-off: availability is regional, and some time-saving features require Pro.
5. PayPal Invoicing — best for familiar international payments
PayPal invoices can be sent without a monthly invoicing fee, and customers can use supported cards, wallets, or bank options. The tool supports customization, taxes, discounts, estimates, reminders, recurring invoices, and payment-status tracking.
Best for: freelancers whose clients already prefer PayPal or who work across borders.
Why choose it: payment familiarity can reduce client hesitation.
Trade-off: transaction and currency-conversion fees can take a noticeable bite out of project revenue.
6. Square Invoices — best for freelance services delivered in person
Square links estimates, contracts, deposits, invoices, recurring schedules, reminders, and payments. It is especially convenient when you sometimes accept a card in person and sometimes invoice remotely.
Best for: photographers, tutors, coaches, mobile professionals, and local service providers.
Why choose it: online and in-person payments stay in one customer record.
Trade-off: it makes the most sense when Square is already part of the business.
7. QuickBooks Solopreneur — best for tax organization
QuickBooks' freelancer-focused offering connects business income and expenses with invoicing and tax-oriented organization.
Best for: self-employed people who choose software primarily for bookkeeping and tax preparation.
Why choose it: broader financial records can reduce year-end cleanup.
Trade-off: it costs more and takes longer to learn than a focused invoice generator.
Features freelancers should prioritize
Flexible line items
The software should support hours, fixed project fees, quantities, reimbursable expenses, discounts, and tax without awkward workarounds.
Repeat-client speed
Saved contacts and business details matter more after the first month than an oversized template gallery.
Clear payment terms
Your invoice should make the due date, currency, payment method, reference, and late-payment expectations obvious.
Recurring retainers
If a client pays the same amount every month, recurring invoices can remove an entire administrative task.
Delivery and status
Email delivery, open tracking, reminders, and a visible paid/unpaid state reduce guesswork when a payment is late.
Final verdict
InvoiceSonic is the best overall choice for freelancers who want a focused invoice workflow and a free way to start. FreshBooks wins for detailed time billing, Zoho Invoice for free automation, Wave for bookkeeping, PayPal for payment familiarity, Square for in-person services, and QuickBooks for tax-led financial management.
