This invoicing app project will test you on many levels. You'll be working with JSON data, managing state, plus a lot more. You can even build it out as a full-stack app!
- Sketch and Figma design files
- Mobile, tablet & desktop layouts
- Professional design system for colors, fonts, etc
- Optimized image assets
- README file to help you get started
- HTML file with pre-written content
Your challenge is to build out this invoicing application and get it looking as close to the design as possible.
You can use any tools you like to help you complete the challenge. So if you've got something you'd like to practice, feel free to give it a go.
We provide the data in a local
data.json file, so use that to populate the content on the first load. If you want to take it up a notch, feel free to build this as a full-stack application!
Your users should be able to:
- View the optimal layout for the app depending on their device's screen size
- See hover states for all interactive elements on the page
- Create, read, update, and delete invoices
- Receive form validations when trying to create/edit an invoice
- Save draft invoices, and mark pending invoices as paid
- Filter invoices by status (draft/pending/paid)
- Toggle light and dark mode
- Bonus: Keep track of any changes, even after refreshing the browser (
localStoragecould be used for this if you're not building out a full-stack app)
- Bonus: Build this project as a full-stack application

Ideas to test yourself
Build the project out as a full-stack application
Train your eye for detail by getting your solution as close to the design as you can
Try estimating the time it will take for you to build the project. Then see if the time taken matches up to your estimate. Project estimations are a skill that is often overlooked, but is important for professional developers
Can I use libraries/frameworks on these projects?
Yes! Our challenges provide professional designs but there are no rules on what tools to use. So feel free to use anything you like to build your projects.
How can I get help if I'm stuck on a challenge?
The best (and quickest) way to get help on a challenge is in our Slack community. There are thousands of other developers in there, so it's a great place to ask questions. We even have a dedicated “help” channel! If you haven't joined yet, you can get an invite to our Slack community here.
Can I use these projects in my portfolio?
Definitely! Please do feel free to use whatever you build in your portfolio. Helping developers add professional-looking projects to their portfolio was one of the reasons we created this platform!
Is there an official solution I can take a look at?
We don't provide “official” solutions for the challenges. This is because there is no single perfect way to complete a challenge. Instead, you're encouraged to review other people's code in the community. You can learn so much by seeing how other people have approached the same challenges and giving them feedback.
Do I get a code review when I post my solution?
Frontend Mentor is a collaborative learning community where everyone can give feedback to each other. If you'd like to receive feedback from the community, please be sure to post a question when you submit your solution. The more specific you can be, the better. Being clear with your questions means you're much more likely to receive valuable feedback from others.
How do I submit my solution?
We'd recommend reading our complete guide to submitting solutions. If you get stuck and need help, please feel free to ask questions in our Slack community, and we'll help you submit your project.
