Invoicing is simple enough in theory. In practice it piles up fast: manual reminders, missed payments, numbers scattered across different tools. Good invoicing software takes most of that off your plate.
Here is our selection of invoicing software for small businesses and self-employed individuals. Some are dedicated invoicing tools; others are full accounting platforms with invoicing built in.
What to look for in invoicing software
Not all invoicing tools are built the same. Before choosing one, check that it covers these areas:
- Automation — recurring invoices and payment reminders should run without manual input each cycle
- Payment acceptance — online payment processing via cards, ACH, or direct bank transfer removes friction for clients and speeds up collection
- Accounting integration — invoicing should connect to your broader financial records so you are not reconciling data across separate systems
- Customization — professional invoices with your branding, adjustable line items, and support for taxes relevant to your region
- Ease of use — if the tool requires accounting expertise to operate, adoption will stall; look for interfaces designed for business owners, not just accountants
Top invoicing software for small businesses
1. actiTIME
- Combines time tracking and invoicing
- Free for up to 3 users
- Robust cost and billing reports
Time tracking is the main event in actiTIME, and billing and invoicing sit right alongside it. Billable amounts come from recorded time and the billing rates you set per type of work, so the invoice reflects what was actually spent rather than a number put together from memory.
Accountants and project managers get a full breakdown of billable and non-billable activity by customer, project, or task. From there you can build invoices, customize them, and export to PDF for email or print. If you invoice the same client on a regular cycle, save the invoice as a template and reuse it without starting from scratch each time.
actiTIME runs as an online service with daily backups, or on your own server if your company policy requires keeping billing data within its internal network. The permanent free version covers up to 3 users with no time limit and no credit card required.
Time tracking became a breeze
With actiTIME’s mobile app, tracking time on the client’s side became a breeze. Now accountants simply switch on the timer on their phone as they start another task and get accurate time logs without taking notes.
2. QuickBooks
- The most popular accounting platform
- Fits teams of any size
- Advanced invoicing features
QuickBooks is one of the most widely used accounting and invoicing platforms around, covering businesses from sole traders to mid-size teams. Income and expense tracking, cost management, payroll, and client invoicing all live in one product, which works well for businesses that want a single system rather than several loosely connected ones.
QuickBooks automates the invoicing cycle: online invoices accept payments directly, free ACH transfers cut out bank paperwork, and multi-currency support handles the math on international billing. Both desktop and mobile access are included.
3. Zoho Books
- Part of an integrated platform
- Automation of invoice management
- For companies of any size
Zoho Books is the accounting and invoicing piece of the broader Zoho ecosystem, which also covers sales, marketing, helpdesk, and HR. If your business already uses other Zoho products, adding Zoho Books means invoicing connects directly to the rest of your operations without extra data transfer or integrations to maintain.
The invoicing module handles the standard workflow: professional invoices, brand customization, and automated payment reminders so overdue chasing does not fall to you. Zoho Books has a free plan for businesses under a certain annual revenue threshold, which makes it accessible for early-stage companies that need accounting features before they are ready to pay for them.
4. FreshBooks
- Simple invoicing for small businesses
- Autopilot mode
- Affordable prices
FreshBooks is for small business owners who want accounting to take as little time as possible. Its autopilot mode covers recurring invoices, automated reminders, and late fees. Set up a client’s billing schedule once and the system handles the rest.
FreshBooks says its users get paid up to 11 days faster, partly because you can request deposits on invoices rather than waiting until the project is finished to collect. Time tracking data connects to invoicing directly, so billable hours flow into the invoice without manual entry.
5. Sage
- Cloud accounting for small businesses
- Invoicing alongside VAT, expenses, and reporting
- Scalable from basic invoicing to full accounting
Sage’s small business software is a well-established cloud-based accounting platform that includes a comprehensive suite of invoicing software tools designed for small businesses and sole traders. It allows users to create and send professional invoices, automate payment reminders, and track outstanding balances in real time — all from a single dashboard.
Sage is particularly well-suited to businesses that need their invoicing to sit alongside VAT management, expense tracking, and financial reporting without juggling multiple separate tools. For small businesses looking to grow without outgrowing their software, Sage offers scalable plans that expand from basic invoicing to full accounting functionality as needs develop.
6. Billings Pro
- Cost estimates for customers
- Simple account management
- Works for freelancers and teams
Billings Pro gets invoicing running quickly. It supports invoice customization, desktop and iOS editing, and sending on the go. Useful for freelancers and small teams that need to bill clients between jobs rather than from a fixed desk.
It also handles cost estimates. Build a detailed proposal using a ready-made template, adjust it to the project scope, and send it before work starts. Getting agreement on the numbers upfront tends to make the final invoice a much easier conversation.
7. Sighted
- Accounting for non-accountants
- 100% free online invoicing
Sighted is a free invoicing tool for small business owners without an accounting background. It covers expense tracking, invoice creation, online payments, and basic financial reporting, none of which requires specialist knowledge to use.
The platform lets you build and manage records for customers, products, and services, generate PDF invoices, and export data in CSV format. SSL encryption is applied throughout, so sensitive billing data stays protected.
8. Due
- A great tool for freelancers
- Rich invoice management options
Due is an invoicing tool for freelancers and small business owners who handle billing on their own. The design focuses on reducing time in the invoicing cycle and catching the errors that come up without an accounting background: missed payments, wrong tax calculations, that kind of thing.
Features cover creating and sending invoices, tracking due and overdue amounts, handling partial payments, and managing multiple sales tax configurations. The range is broad enough for most freelance and micro-business scenarios without overcomplicating the interface.
9. Paydirt
- Automatic invoice creation
- Streamlined invoice tracking
- Recurring invoices
Paydirt is for freelancers and small teams that bill by the hour. It calculates billable amounts from logged time and generates invoices automatically, so there is no manual step between work recorded and invoice sent.
Core features include invoice creation, a view of unbilled work and outstanding invoices, and automatic payment tracking. The app supports 52 currencies and runs entirely online, so no local setup is required.
FAQ
What is the best invoicing software for small businesses?
It depends on how your billing works. If you bill by time, actiTIME is the most direct option: time records connect straight to invoices with no manual step in between. If you need a full accounting package with invoicing included, QuickBooks and Zoho Books are the most established options at different price points.
What is the best free invoice software for small businesses?
actiTIME has a permanent free version for up to 3 users covering time tracking and billing reports, no trial period and no credit card needed. Zoho Books has a free plan for businesses under a certain annual revenue threshold. Sighted offers free invoice creation with no paid tier required. Which one fits depends on whether you need standalone invoicing or invoicing tied to time tracking and project records.
Is QuickBooks free for invoicing?
No. QuickBooks has a 30-day free trial, after which a paid subscription is required. If cost is the main concern, actiTIME or Zoho Books are more accessible starting points for small teams that need invoicing without a full accounting subscription.
