Best Invoicing Apps for Freelancers

An invoice is more than a bill. It tells a client what you did, what they owe, when it is due and how to pay. A good invoicing app makes that process faster and more professional. It can send reminders, accept card or bank payments and keep a record you can use at tax time.

Many freelancers start with a template in a word processor. That works at first, but it becomes hard to track who has paid, who is late and what you billed in a given month. Invoicing apps solve those problems, though each one suits a slightly different way of working.

This guide describes six tools that freelancers often consider. Features, fees and plans change, so always check current details on the provider's site before you commit.

What a freelancer needs from an invoicing app

• Professional, customizable invoice templates with your own branding
• An online payment link on every invoice
• Automatic payment reminders before and after the due date
• Recurring invoices for retainers or monthly work
• Time tracking, if you bill by the hour
• Expense tracking, so you can separate costs from income
• Multi-currency support, if you have clients abroad
• Clear records you can export for your accountant
• A mobile app for sending invoices on the go

You may not need every item. Start with the two or three that solve your biggest problem.

The six options

FreshBooks

FreshBooks is widely known for invoicing, time tracking and expense tracking in one place. Its interface is designed for service businesses and freelancers who bill by project or by the hour. It generally suits consultants, designers, writers and agencies that want their time logs to turn straight into invoices.

Wave

Wave is known for free invoicing tools aimed at small businesses, with card payment processing fees and paid add-ons in some regions. It generally suits freelancers on a tight budget who need simple, professional invoices and do not need heavy time-tracking features. Check which payment options and fees apply where you live.

Zoho Invoice

Zoho Invoice is a lower-cost invoicing tool within the wider Zoho family. It offers templates, recurring billing, automated reminders and connections to payment gateways. It generally suits freelancers who want good automation at a modest cost, especially those who already use other Zoho apps. Confirm whether a free plan covers your volume before you rely on it.

Invoice Ninja

Invoice Ninja is an invoicing platform that is available as a hosted service and can also be self-hosted. It generally suits technically confident freelancers who want more control over their data or more flexibility in how invoices are built. Setup and maintenance take more effort than a simple hosted app.

PayPal invoicing

PayPal lets you create and send invoices from a PayPal account, with a payment link that clients can use to pay. It generally suits freelancers who already receive payments through PayPal and want a quick way to bill. Transaction fees apply to payments, so check PayPal's current fee information for your country and currency.

Bonsai

Bonsai is built for freelancers and small agencies. It goes beyond invoices, with tools for proposals, contracts, time tracking and client management in one place. It generally suits freelancers who want to handle a client from the first proposal through to payment. Check which plan includes the features you need.

Comparison table

Worked example: what you actually receive

Suppose you invoice a client 1,000 for a design project. The client pays by card, and the payment provider charges a fee. For this example, assume a fee rate of 3 percent. This is an illustrative figure only. Real fees vary by provider, payment method and country.

• Invoice total: 1,000
• Fee: 1,000 × 3% = 30
• Amount you receive: 1,000 - 30 = 970

Now suppose the same client pays a second invoice of 500 by bank transfer, which in this example has no fee.

• Invoice total: 500
• Fee: 0
• Amount you receive: 500

Across both invoices you billed 1,500 and received 1,470. The 30 difference is the card fee. Knowing this lets you decide whether to add the fee to your price, ask for bank transfer, or build the cost into your rates.

A simple reminder schedule

Late payment is a cash flow problem, so plan your follow-up in advance. One sample schedule looks like this:

• A few days before the due date: a friendly reminder with the payment link
• On the due date: a short note confirming the invoice is due today
• One week after the due date: a clear reminder and a request for a payment date
• Two weeks after the due date: a direct call or message to discuss the account

Most invoicing apps can automate the first two or three steps.

Steps to choose and set up

1. List what you bill for: hours, projects, retainers or products.
2. Note the currencies and payment methods your clients use.
3. Shortlist two or three apps that match your list.
4. Check current pricing, payment fees and plan limits on each provider's site.
5. Try a free trial, where one is offered, by sending one real invoice to a friendly client.
6. Set your payment terms, invoice numbering and reminder schedule.
7. Connect the app to your bank or accounting software if you use one.

Getting paid faster

• Invoice as soon as the work is done, not at the end of the month.
• State your payment terms clearly on every invoice.
• Ask for a deposit on large projects.
• Put the payment link on every invoice so paying is easy.
• Keep a simple list of overdue invoices and review it each week.

Frequently asked questions

Do I need invoicing software if I already use a spreadsheet?

Not necessarily. A spreadsheet can work for a few clients and a small number of invoices. Software becomes useful when you need reminders, online payment, recurring billing or a clear record of who has paid. Switch when manual work starts to cause mistakes.

Are free invoicing apps good enough?

They can be, for freelancers with simple needs. Check what the free version includes, such as the number of invoices, the payment options and any fees on each payment. A free tool that is missing a key feature can cost more time than a paid one.

Which app is best for international clients?

Look for multi-currency support, clear information about exchange rates and fees, and payment methods your clients already use. Exchange rates and fees change, so check them directly with the provider. Keep records of every invoice and payment for your accountant.

Should I keep copies of my invoices?

Yes. Keep records of invoices, payments and expenses in line with the rules where you live. Tax and record-keeping requirements vary by country, so a qualified accountant or adviser can confirm what you need to keep.
