Best Invoicing Software for Freelancers and Small Business

What Invoicing Software Should Handle

At minimum, invoicing software should let you create professional invoices with your branding, send them electronically to clients, accept online payments through credit card and bank transfer, send automatic payment reminders, and track which invoices are paid, outstanding, and overdue. These core features are available in every tool on this list, including the free options. The differences that matter are in the workflow surrounding the invoice: how the tool connects to your time tracking, how it handles recurring billing, what payment methods your clients can use, and how invoice data flows into your financial reporting.

For freelancers and consultants who bill by the hour, the integration between time tracking and invoicing is the most valuable feature. Tracking time against projects and then manually calculating billable amounts and typing them into invoices introduces errors and wastes 30 to 60 minutes per billing cycle. A tool that lets you start a timer on a project, stop it when you finish, and then convert all logged hours into invoice line items with a few clicks eliminates both the math errors and the administrative time.

For product-based businesses that invoice wholesale buyers or B2B customers, the important features are product catalogs that populate invoice line items automatically, quantity-based pricing and discount tiers, purchase order reference fields, payment terms beyond immediate payment (net 30, net 60), and sales tax calculation by jurisdiction. These features are less universal than basic invoicing and are often limited to paid plans or tools that target B2B commerce specifically.

FreshBooks: Best for Service Businesses

FreshBooks costs $19 per month for the Lite plan (5 billable clients), $33 per month for Plus (50 clients), and $60 per month for Premium (unlimited clients). All plans include customizable invoices, online payment acceptance, automatic payment reminders, expense tracking, time tracking, and basic financial reporting.

FreshBooks' invoicing experience is the most polished in the market. Creating an invoice takes under two minutes: select the client, add line items from your service catalog or logged time entries, review the total, and send. The invoice lands in your client's inbox with your branding, a clear payment due date, and a prominent "Pay Now" button that lets them pay by credit card, bank transfer, or Apple Pay. Automatic reminders go out before the due date, on the due date, and after the due date at intervals you configure, which saves the awkward manual follow-up emails that freelancers dread.

The time tracking integration is FreshBooks' strongest differentiator for service businesses. Log time against specific projects and clients using the desktop timer, mobile app, or Chrome extension. When you create an invoice, FreshBooks offers to populate it with all unbilled time entries for that client, calculated at the project's hourly rate. You can review and adjust individual entries before sending, but the heavy lifting of calculating billable amounts and creating line items is automated. For freelancers who bill 5 to 20 clients monthly, this integration saves two to four hours of administrative work per billing cycle.

FreshBooks also includes a client portal where your clients can view all invoices, make payments, and communicate with you about specific invoices without email back-and-forth. The deposit and retainer feature lets you collect partial payment before starting work, with the deposit amount automatically deducted from the final invoice. These workflow features address real pain points in the client-vendor payment relationship that basic invoicing tools ignore.

The limitation is the per-client pricing on lower tiers. The Lite plan's 5-client limit means freelancers with a moderate client roster need the $33 Plus plan from the start. For businesses that primarily need invoicing without the time tracking and expense management features, FreshBooks' pricing is steep compared to free alternatives that handle the core invoicing workflow adequately.

Wave: Best Free Invoicing

Wave's invoicing is completely free with no client limits, no invoice limits, and no feature restrictions. Wave charges for payment processing (2.9 percent plus $0.60 per credit card transaction, 1 percent for bank payments with a $1 minimum) and payroll ($40 per month base plus $6 per employee). The invoicing itself, including customization, automatic reminders, and recurring invoices, costs nothing.

Wave's invoicing creates professional, branded invoices that clients can pay online through credit card or bank transfer. The customization options let you add your logo, choose colors, add custom fields, and write personalized notes. Recurring invoices run automatically on whatever schedule you set, which is valuable for businesses with subscription clients, retainers, or monthly service agreements. The automatic reminder system sends configurable notifications before and after due dates.

Because Wave also provides free accounting software, invoices created in Wave automatically appear in your books as accounts receivable. When a client pays, the payment is recorded against the invoice and reflected in your financial reports without any manual entry. This invoicing-to-accounting pipeline is the main reason to choose Wave over other free invoicing tools that handle invoicing in isolation without connecting to your financial records.

Wave's limitation is the payment processing cost. The 2.9 percent plus $0.60 per transaction for credit card payments is competitive with industry rates, but the $0.60 fixed fee makes Wave expensive for small transactions. A $50 invoice paid by credit card costs $2.05 in processing fees (4.1 percent effective rate), while a $500 invoice costs $15.10 (3.0 percent effective rate). For freelancers sending large invoices, this pricing is reasonable. For businesses processing many small transactions, the fixed fee adds up. You can reduce costs by encouraging clients to pay by bank transfer at 1 percent.

Zoho Invoice: Best for International Invoicing

Zoho Invoice is free for businesses sending up to 1,000 invoices per year to up to 50 customers. The paid plans through Zoho Books start at $15 per month and add full accounting capabilities alongside the invoicing features. All Zoho Invoice plans include multi-currency support, multi-language invoices, online payment acceptance through multiple gateways, and automated payment reminders.

The multi-currency and multi-language capabilities make Zoho Invoice the strongest option for businesses that invoice international clients. You can create invoices in the client's currency with automatic exchange rate calculation, generate invoices in 14 languages, and accept payments through region-specific payment gateways. For a US-based consultant invoicing European clients in euros and Asian clients in yen, Zoho Invoice handles the currency conversion, tax calculation, and payment collection without requiring separate tools for each currency.

Zoho Invoice integrates natively with the broader Zoho ecosystem, including Zoho CRM for converting quotes to invoices, Zoho Projects for billing project milestones, and Zoho Books for complete accounting. If your business uses multiple Zoho products, the invoice data flows seamlessly between systems without third-party connectors. The client portal lets clients view invoices, accept estimates, track project progress, and make payments through a single branded interface.

The limitation is Zoho's smaller presence in the US market compared to FreshBooks and QuickBooks. Finding an accountant familiar with Zoho Books can be more challenging, and some US-specific features like 1099 contractor reporting require workarounds. For international businesses or those already using Zoho products, these limitations are minor. For US-only businesses without existing Zoho adoption, FreshBooks or Wave may provide a smoother experience.

Square Invoices: Best for Payment Flexibility

Square Invoices is free for unlimited invoices with payment processing at 2.9 percent plus $0.30 per online card payment or 3.5 percent plus $0.15 for manually entered cards. The Plus plan at $20 per month adds custom invoice templates, milestone-based payment schedules, automatic payment receipts, and contract attachments.

Square's advantage is payment flexibility. Clients can pay invoices by credit card, debit card, Apple Pay, Google Pay, Cash App, or ACH bank transfer. The ability to accept payment through Cash App is unique and increasingly relevant as younger business owners and consumers prefer mobile payment apps. For businesses whose clients span multiple payment preferences, Square removes the "I cannot pay because you do not accept my preferred method" friction that delays payment collection.

If you already use Square for point of sale payments, adding Square Invoices keeps all your revenue data in one dashboard. In-person sales and invoiced payments appear in the same reporting, giving you a complete view of business income without reconciling data from separate systems. The customer profiles accumulate both in-store purchases and invoice payments, creating a unified customer record that tracks total lifetime value across all payment channels.

The limitation is that Square Invoices lacks the depth of dedicated invoicing tools for time-based billing, project tracking, and expense management. It does not include time tracking, and the reporting capabilities are basic compared to FreshBooks or Zoho. Square Invoices works best for businesses that send straightforward invoices for products or fixed-price services and want the simplest possible path from invoice creation to payment collection.

Choosing the Right Invoicing Tool

For freelancers and consultants who bill by the hour and need time tracking connected to invoicing, FreshBooks provides the most streamlined workflow despite the subscription cost. For freelancers and small businesses that want capable invoicing without a monthly bill, Wave delivers full-featured invoicing with the bonus of free accounting software. For businesses invoicing international clients in multiple currencies, Zoho Invoice handles the complexity that other tools struggle with. For businesses already using Square for in-person payments, Square Invoices provides unified revenue tracking across all payment channels.

If you already use accounting software, check whether it includes invoicing before adding a separate tool. QuickBooks, Xero, FreshBooks, Wave, and Zoho Books all include invoicing as part of their accounting platforms. Adding a standalone invoicing tool on top of your accounting software creates duplicate data entry unless the two tools integrate, which adds complexity without adding value.
