Best Invoicing Software for Freelancers and Small Business

This page sets seven invoicing tools side by side using one kind of evidence: what each vendor's own pricing page said when we read it on 9 October 2026. Every entry links to that page. We did not sign up for or test these products, so the entries describe plans, prices and published limits, not how the software feels to use.

Prices are monthly list prices in US dollars, from the vendor's US page where it has one. Several vendors were running introductory discounts that day, and vendors change plans and price by country, so check the linked page before you buy. QuickBooks Online is listed without details: its site refused every connection from our check vantage, and we do not describe a product whose page we could not read.

How this page was put together

For each tool we fetched the vendor's pricing page and took from it the plan names, the monthly prices, what the plans include and the limits the page states (clients, invoices, users). Where a page gives two prices for one plan, for monthly and for annual billing, both appear and are labelled. The tools are listed alphabetically. That order is not a ranking, and the page makes no claim about which tool is better.

No vendor link on this page is an affiliate or paid link; the only links to vendors are the source lines on each entry. An automated weekly check re-reads each linked pricing page and flags it when the plan wording an entry relies on is no longer there.

The seven tools, in alphabetical order

Per user per month: Basic $15, Essentials $25, Premium $39 and Elite $59 billed monthly; $9, $19, $29 and $49 when paid annually. Elite has a three-user minimum.

Matching a tool to what you need

To pay nothing: Wave's Starter plan is $0 with unlimited invoices; Zoho Books Free is free on the US page while revenue for the financial year does not exceed $50K, with up to 1,000 invoices a year; Invoice Ninja's free plan covers up to 5 clients.

To bill a small, fixed set of clients: FreshBooks Lite sends invoices to 5 clients and Plus to 50, Invoice Ninja's free plan stops at 5 clients, and Xero's Early plan is limited to 20 invoices.

To invoice in more than one currency: on the pages we read, Xero lists multiple currencies on Established only, Zoho Books lists multi-currency transactions from Professional, and Invoice Ninja's free plan lists automatic currency conversions.

To keep proposals and contracts in the same tool: Bonsai lists proposals and contracts from its Essentials plan, the same plan that adds invoices, and FreshBooks lists proposals from Plus.

To run the software on your own server: Invoice Ninja publishes its source code on GitHub under the Elastic License 2.0.

Calculator tools that pair with your invoicing software

Whichever tool you pick, the arithmetic of payment terms, late interest and calendar-day against business-day windows is the same. These calculators on this site work it out:

Frequently Asked Questions

Which of these invoicing tools have a free plan?
Three, on the pages we read on 9 October 2026: Wave Starter ($0, unlimited invoices), Zoho Books Free (on its US page, free while revenue for the financial year does not exceed $50K, for one user plus an accountant, up to 1,000 invoices a year) and Invoice Ninja Free (up to 5 clients). FreshBooks offers a 30-day free trial instead of a free plan. Every Bonsai and Xero plan on their pages carries a price.
Do these tools send late-payment reminders automatically?
Their pricing pages list it for Wave Pro (reminders 3, 7 and 14 days after the due date), Invoice Ninja Pro and above, and Zoho Books from the free plan. FreshBooks lists automated late payment reminders and scheduled late fees among its plan features. To work out the due date a reminder counts from, the invoice due date calculator on this site handles calendar-day, business-day and end-of-month terms.
Are the prices on this page what I will pay?
Not necessarily. They are the list prices each vendor's page showed in US dollars on 9 October 2026, before tax. FreshBooks and Xero were advertising introductory discounts that day, annual billing lowers the monthly figure for Bonsai, Invoice Ninja and Zoho Books, and vendors set different prices by country. The pricing page linked on each entry is the authority.
Why does QuickBooks Online have no details?
Because we could not read its pricing page. On 9 October 2026 quickbooks.intuit.com reset every connection from the vantage we check sources from. This page only states what a vendor's own page says, so the QuickBooks entry stays empty until that page can be read.
