Zoho Invoice holds a wide lead for free, full-featured invoicing with automated client portals. Individual buyer questions divide their suggestions among several tools without pointing to a single choice.
If you're looking for simple invoicing tools for a small team that won't add another monthly expense, I'd start with Zoho Invoice, Square Invoices, Wave, and Invoice Ninja. They offer free options, but differ in team size, accounting features, and how they handle online payments.
5 invoicing tools worth considering
1. Zoho Invoice
(Best overall free option)
$0/month
Create invoices and estimates, schedule recurring invoices, send payment reminders, track expenses, and manage projects. The free US plan supports up to two users and includes a customer portal.
Send invoices and estimates, schedule recurring invoices, track payment status, and collect deposits. Particularly convenient if you already use Square to accept payments. Online payment processing fees still apply.
Best for: Contractors, local businesses, and teams that accept card payments.
Combines invoicing with basic bookkeeping and accounting, so you can manage customer bills and business finances in one place. Some automation and advanced features require a paid plan; payment processing costs extra.
Best for: Small businesses that want invoicing and bookkeeping together.
Offers invoicing, recurring billing, estimates, and payment integrations. The hosted free plan has a limit of five clients according to current plan comparisons; self-hosting is an option if you want more control.
Best for: Freelancers and small teams with a handful of recurring clients, or technical teams comfortable self-hosting.
Create and email invoices without a monthly subscription. Customers can pay through supported PayPal and other payment methods, depending on availability. Transaction fees apply, and accounting and team-management features are more limited than dedicated business platforms.
Best for: Small teams that want to invoice clients quickly with minimal setup.

My recommendation
For a team of two: Start with Zoho Invoice.
For a business with several employees: Check Square's team and account permissions, or verify whether Zoho's current free limit will accommodate everyone who needs access.
For invoicing plus accounting: Try Wave.
For maximum customization: Consider Invoice Ninja.
One important distinction: a free invoicing plan doesn't necessarily mean free payment collection. Card processing, bank transfers, and other payment methods may incur fees.
How many people need to use the invoicing tool? If you tell me whether it's just 2–3 people or a larger team, I can narrow this down to the best free options that fit your team size.
Here are some of the best, most straightforward invoicing tools that feature a functional free tier, well-suited for small teams or freelancers who want to keep administrative overhead low:
Wave Invoicing
Best for: Completely unlimited free invoicing and basic accounting.
Free Tier Details: Wave offers 100% free invoice creation, tracking, and customer management with zero caps on the number of invoices or clients you can have.
The Catch: They make money via transaction processing fees if your clients pay directly through an online "Pay Now" button using credit cards or ACH.[](https://zapier.com/blog/best-free-invoice-software/)
Square Invoices
Best for: Teams already utilizing the Square ecosystem or needing fast online/in-person payment sync.
Free Tier Details: Free-to-use plan that allows you to send unlimited invoices, estimates, and digital contracts.
The Catch: Like Wave, there is no monthly subscription fee for the basic tier, but you pay standard processing fees (typically around 2.9% + $0.30) when a customer pays online.[](https://zapier.com/blog/best-free-invoice-software/)
Best for: Feature-rich custom branding and client portals.
Free Tier Details: The forever-free cloud plan lets you manage up to 5 clients with unlimited invoicing. (If you self-host the open-source version on your own server, it removes client limits completely).
The Catch: Limited to 5 clients on the free cloud-hosted plan; upgrading unlocks unlimited clients and advanced automations.[](https://invoiceninja.com/)
Zoho Invoice
Best for: Small service-based teams wanting robust features without a price tag.
Free Tier Details: A genuinely free (not trial-limited) standalone invoice app that supports up to 3 user accounts and handles up to 1,000 invoices per year.
The Catch: Customer support on the free tier is restricted to email-only, and you are capped at the 3-user/1,000-invoice limits.
Free Tier Details: A no-frills, fast-setup dashboard allowing you to send professional invoices and estimates.
The Catch: The free plan includes Invoicely branding on your invoices and limits your direct payment gateways primarily to PayPal.
If you can tell me how many clients or invoices you expect to handle per month, and whether you need time-tracking or multi-user access , I can help you pick the best fit for your workflow.
For a small team, there are several good invoicing tools that let you create and send invoices without paying a monthly subscription. The main differences are how many people can use the software, whether invoices are unlimited, and whether you also need bookkeeping or online payment processing.
I'd start by comparing these five options, focusing on plans that offer ongoing free access rather than just a free trial.

Zoho Invoice if you want a dedicated invoicing tool with reminders, estimates, and recurring invoices.
Square Invoices if multiple teammates need access and you want to send unlimited invoices without a monthly subscription.

You can start with the official sites above and compare their free plans before entering your business information.
One question that would help narrow this down: How many people on your team need to create or manage invoices — just one person, 2–5 people, or more than 5?
For a small team looking for simple invoicing software with a free tier or completely free access, several strong options exist . Most "free" invoicing tools make their money via payment processing transaction fees when your clients pay online, but the software itself won't charge you a monthly subscription.
For a small team looking for simple billing software, there are several solid options with a free plan that lets you create and send invoices without a monthly subscription. The main differences are how many users and customers you can manage, whether recurring billing is included, and what you pay to accept online payments.

Which would I choose?
For a small team, I'd start by comparing Zoho Invoice, Wave, and Square. They're the most useful starting points depending on whether you need invoicing, bookkeeping, or payment collection.
