The best invoicing software in 2026

Work's done, time to get paid. But that's not as easy as emailing a reminder: you need to send a professional invoice with clear payment terms, accurate line items, and all your business and client details.

You can do that with a Google Docs template, for sure. But when you're copying everything every time, it's easy to forget to include a key element like a payment link. Even if you get everything right, the real headache kicks in: Who has paid? Who hasn't? What's overdue? And that's you diving into scattered files, trying to piece that together as your tax deadline looms. There's a solution to all of this: an invoicing app.

I considered over 100 invoicing apps and did in-depth testing to help you get paid with peace of mind.

What makes the best invoicing software?

Invoicing apps make your payment workflows easier and more consistent. Generate invoices as needed, track payments, send reminders to late payers, and get a real-time view of your cash flow. No spreadsheets. No guesswork. No chasing down payment status across three or four apps.

Here's what I looked for in the best invoicing software.

• Speed and ease of use. Your invoice maker app has to be faster than filling out a document template and easy to figure out in five minutes or less. If it's only for invoicing, it better be simple to use.

• Focus on invoicing. All the apps on this list have their invoicing features front and center, even if they offer a wider range of possibilities. I don't want you to be digging around complex menus to find that Create invoice button.

• Ability to receive payments online. I chose apps that have online payment platform integrations, letting your clients pay you online. If you don't need this functionality, you can just use an invoice generator instead of a dedicated invoicing app.

• Design. Clean, beautiful invoices make a better impression on your clients, helping you stand out. Not an essential, but a huge plus.

• Unique features. Keeping the focus on invoicing, I looked for extras that expand this core use case, without making it too complex. Examples are sales features, handy integrations with other platforms, or unique ways to send your invoices.

Beyond two that I use every month as a freelancer, I signed up for each of these invoicing apps (and dozens of others) and spent between one and two hours testing each. I walked through the core flows of creating invoices, browsing dashboards, and judging whether the extra features were genuinely useful.

Before we get into it: if you're already using an accounting app, it may have invoicing features embedded in it. While it's pretty obvious in most cases, a couple of well-known solutions have invoices disabled by default, which means you have to search for and activate the feature in the settings section. Take a quick look at your own accounting app to see if that's the case.

Since invoicing often requires a specific feature, I put together this table to help you jump quickly to the apps that actually have what you need.

Best invoicing software for brand recognition

PayPal (Web, iOS, Android)

PayPal pros:

• Strong security

• Plenty of merchant features

PayPal cons:

• Your account can get restricted or blocked out of nowhere if PayPal detects suspicious activity

As a freelancer or small business still building a reputation, getting clients to pay quickly can be an uphill battle. PayPal solves this by lending you its brand recognition. Launched in 1999, it's become synonymous with secure online payments—and when your invoice arrives with that familiar logo, clients are more likely to trust and pay without hesitation.

Invoicing is one of the many possibilities it offers. To get there, log in to your account and click the Create an invoice link on the right side. The invoice creation screen is simple, helping you focus on what you need to do. It feels like a banking app—serious vibe and all—which makes it pretty intuitive if you do most of your banking online.

PayPal also processes all online payments itself. When you create an invoice and send it to a client who has a PayPal account, they'll receive a notification on their app, making it easier to pay you in a couple of taps. If that's not the case, your clients can still pay by entering their credit card details. If you do business in person, you can generate a QR code link and show it to your client or get the PayPal POS app to accept them with your smartphone (or via other available POS devices).

One note: the payment processing fees are a bit complicated to figure out, as they vary depending on the payment method, type, and currency. As a rule, you can expect that there's a fixed cost per transaction (usually cents) and a percentage over the total amount. Be sure you understand all the fees before you dive in.

Once you finish that invoice, you can add it to a Google Sheet or sync your client roster to your email marketing tool. And when you connect PayPal with Zapier, you can build more sophisticated, multi-step workflows across your tech stack. For example, when a client submits a PayPal payment, it can automatically get logged in your accounting software, and then use AI to generate a personalized thank-you note or invoice summary.

PayPal price: Commission-based; fees start at $0.49 + 1.5% to 3.49% per transaction.

Best invoicing software for selling on social media

Square (Web, iOS, Android)

Square pros:

• Supports digital wallets like Apple Pay and Google Pay

• Real-time inventory tracking available

Square cons:

• Not very customizable overall

Wish you could spend more time selling on social media instead of juggling the admin? Square integrates directly with Facebook and Instagram, syncing your product catalog and letting you message customers from one place. The setup process is a bit lengthy and requires attention to detail, but the time you'll save with it in the future pays off. Take your time to familiarize yourself with it, and tackle it when you feel ready.

The interface is polished, functional, fast, and easy to use. The invoicing page has lots of options you can configure, such as invoice frequency, when to send it to your client, and which payment methods you'll accept. All the features are on the page—no hidden menus—so you won't forget anything.

To edit the design of your invoices, click Settings and then Customization. There, you can choose from one of three layouts, add your logo, set the invoice colors, and hide or show specific fields. It's not as much as others on this list, but pretty generous considering it's actually a payment platform.

Online payments are processed by Square. It accepts online credit card payments, ACH bank transfers, and gift cards. But it also has a lot of extras, like buy now, pay later support, contract creation, multi-package estimates, milestone-based payment schedules, tipping options, in-person sales, and loads of integrations with restaurant and eCommerce software.

By connecting Square with Zapier, you can orchestrate invoicing workflows across your tech stack. For example, automatically update your inventory when a customer makes a purchase and use AI to forecast demand so you can stay ahead of your customers' needs. Here are other popular ways to automate Square.

Square price: Free plan available for basic platform features, with 2.6% + $0.15 for each tap/dip/swipe transaction and 3.3% + $0.30 online. Square Plus at $49/month reduces transaction fees, POS features, and email/text marketing.

Best invoice app for generating your own sales page

Billdu (Web, iOS, Android)

Billdu pros:

• Packed with website and sales extras

• Tracks quotes, purchase orders, delivery notes, and other related documents

Billdu cons:

• Customer support isn't very responsive

Invoicing doesn't happen in a vacuum: it's part of your sales process. If you want to handle more of that process in one place, Billdu lets you create sales pages, build a simple website, and manage appointment booking alongside your invoicing.

Start by setting up your sales page with your business hours and contact details, a profile, and a header image. You'll also be able to handle online booking, letting your clients schedule discovery calls with you; set up an online store, where you can sell your products and services; let your clients request quotes; and even integrate a live chat feature.

Once you fill out all the details, you can publish it to what Billdu calls an "Instant Website." You'll get a short link you can share wherever you want, with all the information your clients need to do business with you. Already have a website? You can embed the page as a widget there instead.

When the time comes to create an invoice, you can choose your design from five available layouts, all leaning on minimalism, delivering a clean and professional result. When you're done customizing the looks, head over to the Settings section and click Payment options. There, you can add your bank details to your invoices and integrate Stripe or PayPal to receive payments online.

Two other features add agility to your sales process, supporting the invoicing tools well. The first is the quote to invoice conversion, delivering a notification to you as soon as a client accepts your proposal, so you can quickly request payment and start working. The other one is the Inbox, which keeps all client conversations inside the platform: you can read and reply to everything, and quickly check back if anything's unclear about the work.

Billdu price: Free plan available; paid plans start at $7.99/month for unlimited invoices; transaction fees depend on the payment processor you use.

Best invoicing app for creating beautiful invoices

InvoiceQuick (Web, iOS)

InvoiceQuick pros:

• Customer management included

• You can create client portals

InvoiceQuick cons:

• Limited integrations with other apps

You've spent hours perfecting your website. Your proposals are on-brand. Your client presentations are polished. And then you send an invoice that looks like it came from a different company entirely. For businesses where brand consistency isn't negotiable, InvoiceQuick ensures your invoices match the professional identity you've built everywhere else.

There are 28 templates to choose from, from professional to full-blown creative. Pick the one you want, and it's ready to use with a single click. If you want to adapt it to your brand colors, you can change the color scheme, add your logo, and show or hide invoice fields.

The platform is intuitive: all the features you need are available as buttons on all the screens, without hiding much in settings menus. There's an onboarding checklist and tutorial, and it's enough to help you do everything you need to do. You won't have to spend a lot of time in the documentation section to leverage all the app's features.

You can let your clients pay your invoices online by integrating InvoiceQuick with Stripe or PayPal. Bonus: when your clients click the link to see the invoice, you get a notification telling you that they've viewed it. 

Some cool extras here include setting up payment reminders, creating estimates, and accessing a simple report dashboard that includes a cash flow graph, stats about your invoices, and a client activity feed. If you want to go deeper, you can click the Accounting tab and access basic accounting features as well. Despite these extra features, InvoiceQuick still feels focused on invoices, so there's nothing to distract you from the main course.

InvoiceQuick price: Paid plans start at $19/month; transaction fees depend on the payment processor you use.

Best invoicing software for sending invoices via mobile messaging apps

Invoice2go (Web, iOS, Android)

Invoice2go pros:

• Good reporting tools

• Professional invoice templates

Invoice2go cons:

• Limits on the number of invoices you can create

When you log in to Invoice2go, you'll notice that the interface looks professional and polished, a straightforward approach to invoicing. There's a big, useful Create button where you can create anything from a new invoice to a new client. It has an onboarding checklist on the dashboard, and you'll get essential information about invoices, such as total sales volume in the current month and unpaid and overdue totals.

Its primary strength unlocks when you install the mobile app. When you're ready to send an invoice, you can send it via any messaging app you have on your phone. This is great for clients who are easier to reach via WhatsApp or good old SMS. Once they get your invoice, they just have to click the link, and they'll see all the details.

Customizing the look of your invoices is easy, and there are plenty of options. You can pick one of eight layouts, add your own logo and set its alignment, or add a header image and watermarked elements for extra flair. It's quite flexible for the limited number of controls; if you spend some time here, you'll be able to craft something unique with a professional look.

As with most of the competition, Invoice2go integrates with Stripe and PayPal to let your clients pay online. You can also create projects to keep your invoices, estimates, and project notes in one place; add your expenses; and explore integrations with other apps.

If one of your apps isn't on the native integrations list, you can connect Invoice2go to Zapier to access a library of thousands of available apps. This way, you can automatically add clients from other apps—like QuickBooks or Shopify. And when an invoice has been paid, you can automatically update your accounting system and use AI to generate cash flow forecasts.

Invoice2go price: Plans start at $5.99/month; transaction fees depend on the payment processor you use. 

Best invoice app for payment processor options (including crypto)

InvoiceBerry (Web)

InvoiceBerry pros:

• Very straightforward and intuitive

• Supports all core invoicing-related documents and has decent reports

InvoiceBerry cons:

• Limited invoice customization

If you're into Web3, work with Web3 companies, or would like to offer this kind of payment method to your clients, InvoiceBerry is the only one I tested that was both a solid invoicing app and integrated with cryptocurrency platforms Coinbase and CoinPayments. Doing so requires some technical expertise, but if you know how a blockchain works, then pasting an API key should be a piece of cake. 

InvoiceBerry has an appealing user interface—it's fast and intuitive all the way. During onboarding, the creator Uwe Dreiss sends you a personalized welcome video, with some tips on what you can do with his app and how to start exploring. You can't edit the layout of your invoices, but you can add your logo and change the color of the lines you see in the screenshot above. The base design is good enough that it didn't bother me much.

You can create invoices in BTC (Bitcoin) and USDT (Tether), but that's about it as far as the major ones go. Your clients can pay you with cryptocurrencies via Coinbase and CoinPayments, but there are other payment integrations as well: Stripe, PayPal, GoCardless, and Square.

InvoiceBerry also has some extra features like the ability to grant different permission levels, create quotes, log expenses, and run simple reports on your invoicing volume over time.

When you integrate InvoiceBerry with Zapier, you can orchestrate powerful, multi-step workflows that keep your invoicing connected to the rest of your business. For example, automatically generate and send invoices when a project milestone is marked complete, use AI to draft a personalized payment reminder tailored to each client's history, and update your accounting software in real time once an invoice has been paid.

InvoiceBerry price: Plans start at $15/month for unlimited invoices and 35 clients; transaction fees depend on the payment processor you use. 

Best free invoice app

Zoho Invoice (Web, iOS, Android, Windows)

Zoho Invoice pros:

• Lots of invoicing features for free

• Very customizable

Zoho Invoice cons:

• A bit slow to load on desktop and mobile

Zoho Invoice is a powerful and complete invoicing tool, with an attractive price tag on top: free forever. It has everything an invoice app needs without transitioning into the realm of accounting platforms.

Inspired by the enterprise vibe of other Zoho software, Invoice's user interface doesn't dazzle—and that's a good thing. The app is intuitive, offering a lot of information and actions on each screen, so you know what you can do right away.

When creating an invoice, you'll have access to plenty of input fields to add everything, no matter if you're selling products or services. You can customize your invoice with a small selection of visual templates and tweak the layout on a dedicated screen. If you work with clients in multiple countries, it can handle multi-currency, and you can add new invoice templates for each different language.

If you want to explore the extras, click the cogwheel icon on the top-right to open the settings. While there, head to General Preferences and activate the other available modules. The major ones include estimates, expense tracking, and a payment link generator for one-time payments.

Zoho Invoice integrates with a great range of payment processing platforms, including PayPal, Stripe, and Square—and the integration process is easy. A new range of icons pop up both in the online invoice view and in your invoice PDFs. When your clients click on either, they'll be taken to the online payment page, where they'll be able to securely settle that invoice.

As if all of this wasn't enough, Zoho Invoice integrates with Zapier, allowing you to orchestrate sophisticated, AI-powered workflows that tie invoicing seamlessly into the rest of your business operations. For example, when a high-value contract is closed, you can automatically generate an invoice in Zoho Invoice, share an AI-generated summary of payment terms with your finance team, and send a tailored notification to account managers so they can follow up with the client.

Zoho Invoice price: Free

Best invoice app for sending invoices from Gmail

Bookipi (Web, iOS, Android, Gmail add-on)

Bookipi pros:

• Meeting scheduler and team management included

• AI website and AI proposal generators available

Bookipi cons:

• Limited data viewing controls when collaborating with your team

If Gmail is where you are most of the day, why tab out? Bookipi will help you send invoices straight from your inbox out to all your clients—no need to open anything else. Let's walk through the process.

To send a new invoice, open the conversation with the target client. With the Bookipi sidebar open on the right side, you'll notice it'll update with the details about the current conversation. You'll be able to quickly add an invoice tag, items, and prices. When you click Send, a pre-formatted email fires out with a big green Pay Now button (via Stripe or PayPal), a polite message, and the attached invoice. Easy.

To make this possible, Bookipi acts as a Gmail extension, not an actual Chrome extension. It lives on the right sidebar in the Gmail app, not on your browser's Extensions section. This makes the setup process less intuitive than usual, but you won't have trouble getting it done.

The extension is great for sending invoices, but not for much else. To tap into the rest of Bookipi's features, you'll have to head to the web app. You'll have access to all the documents you sent along with reports of your total income—plus a few extra features:

• Proposals lets you pitch new products or services to your clients. Design the cover on Canva, set the timeline, and add the terms of the agreement. You can enable card payments too, so your client can instantly accept and pay.

• eSign is great for quickly signing contracts.

• Instant Website is a relatively impressive AI-powered website generator. Simply add your business name and description of services: it creates a good-looking landing page with hero section, description sections, and even a FAQ, all with images included.

I'm hoping these features get integrated into the Gmail extension at some point. Running an entire freelance toolkit within a Gmail sidebar sounds like productivity heaven to me.

Bookipi price: Free plan available; Starter plan starts at $9.99/month.
