UI / UX Design & Development Contract

This is a sample contract based on the Contract Killer 24 ways posts. 24ways.org/2008/contract-killer/

Between Your Name at Sender's Company and Receiver's Company


We will always do our best to fulfill your needs and meet your goals, but sometimes it is best to have a few simple things written down so that we both know what is what, who should do what and what happens if things go wrong. In this contract you won't find complicated legal terms or large passages of unreadable text. We have no desire to trick you into signing something that you might later regret. We do want what's best for the safety of both parties, now and in the future.

In short

You, Receiver's Company, are hiring Sender's Company located at Sender's Address to redesign and enhance the user interface and user experience of the Early Shares web application for the fixed fee of $00,000. The payment plan and timetable is at the end of the document.

What do both parties agree to do?

As our customer, you have the power and ability to enter into this contract on behalf of your company or organization. You agree to provide us with everything that we need to complete the project including text, images and other information as and when we need it, and in the format that we ask for. You agree to review our work, provide feedback and sign-off approval in a timely manner too. Deadlines work two ways and you will also be bound by any dates that we set together. You also agree to stick to the payment schedule set out at the end of this contract.

We have the experience and ability to perform the services you need from us and we will carry them out in a professional and timely manner. Along the way we will endeavor to meet all the deadlines set but we can't be responsible for a missed launch date or a deadline if you have been late in supplying materials or have not approved or signed off our work on-time at any stage. On top of this we will also maintain the confidentiality of any information that you give us, which shall continue after termination or expiration of this Agreement.

Details of the works

We will redesign and implement the new design in an organized modular way, making scaling the front-end easy and maintainable.This project will take a mobile design first approach targeting mobile devices and working up from there into larger viewports.

This contract includes one main design plus the opportunity for you to make up to two rounds of revisions. If you're not happy with the designs at this stage, you will pay us in full for all of the work that we have produced until that point and you may either cancel this contract or continue to commission us to make further design revisions at the daily rate of $000.00.

Design Overview

HTML/CSS layout templates

HTML markup and CSS templates, we will develop these using valid HTML5 markup and CSS3 for styling.HTML will be generated using the HAML markup language and css will be generated from SASS(SCSS) markup. We will test all our markup and CSS in current versions of all major browsers including those made by Apple, Microsoft, Mozilla and Opera.

In the process of implementing the new design, we will completely refactor the front-end to use object oriented css. This will allow for greater organization and scalability of the front-end piece of the application.

We will also create a basic style guide as reference for the application. This document will describe and document how all objects and elements work and are to be implemented.

Text content

We are not responsible for writing or inputting any text copy unless we specified it in the original estimate. We'll be happy to help though, and in addition to the estimate we will charge you at $00 hour, including a free initial consultation, for copy writing or content input.


If needed, you will supply us photographs in digital format. If you choose to buy stock photographs we can suggest vendors of stock photography. If during the design process photos are needed, we will add placeholders and wait for photographs to be provided.

Changes and revisions

We know from plenty of experience that fixed-price contracts are rarely beneficial to you, as they often limit you to your first idea about how something should look, or how it might work. We don't want to limit your options or your opportunities to change your mind.

We will work closely with you to provide a set of revisions to make sure we are both happy with the final product. Acceptable revisions throughout this engagement are:

• 2 Changes to overall design after submission of page. This is includes the overall page layout and style.

• Minor changes like color, font size, padding, margin, and small placement changes to elements can be submitted at anytime, and you will not be charged.

The quoted price/s at the beginning of this document is a fixed price based on the number of days that we estimate we'll need to accomplish everything you have told us you want to achieve. If you have a change of mind, want to add extra pages or templates or even add new functionality, that won't be a problem. Any changes or additions that you would like to be made outside of the spectrum specified in this contract should be submitted in writing. After receiving a formal request, you will be provided with a quote for said changes. Such changes will be charged at the agreed upon hourly rate and will not exceed the agreed upon daily rate.

No changes will be made without your approval and sign off.

During the performance of this contract or at anytime we provide services to you our hourly rate will be $00 per hour and our daily rate will in no event exceed $720.00 per day.


We have budgeted and estimated the UX & UI Design portion of this project at 6 - 8 weeks.The front-end code, architecture design and implementation is estimated at 4 - 6 weeks.

Legal stuff

We can't guarantee that the functions contained in any web page templates or in a completed web site will always be error-free and so we can't be liable to you or any third party for damages, including lost profits, lost savings or other incidental, consequential or special damages arising out of the operation of or inability to operate this web site and any other web pages, even if you have advised us of the possibilities of such damages.

If any provision of this agreement shall be unlawful, void, or for any reason unenforceable, then that provision shall be deemed severable from this agreement and shall not affect the validity and enforceability of any remaining provisions


You guarantee to us that any elements of text, graphics, photos, designs, trademarks, or other artwork that you provide us for inclusion in the web site are either owned by your good selfs, or that you have permission to use them.

When we receive your final payment, copyright is automatically assigned as follows:

You own the graphics and other visual elements that we create for you for this project. We will give you a copy of all files and you should store them really safely as we are not required to keep them or provide any native source files that we used in making them.

You also own text content, photographs and other data you provided, unless someone else owns them.

We love to show off our work and share what we have learned with other people, so we also reserve the right to display and link to your completed project as part of our portfolio and to write about the project on web sites, in magazine articles and in books about web design.


We are sure you understand how important it is as a small business that you pay the invoices that we send you promptly. As we're also sure you'll want to stay friends, you agree to stick tight to the following payment schedule, which will be as follows, but may be revised based on further conversations between us.

30% of total estimated fee upon agreement of initial design: $0,000

40% of total after UI/UX phase of contract and before beginning design implementation and code architecture/refactor phase: $0,000

Remaining 30% of fee payable not more than 14 days after receipt and acceptance of finished product: $0,000

Interest accrued if payment is more than 14 days late is 5% of outstanding amount to be added every 7 days, starting from 15th day after receipt of finished product.

But where is all the horrible small print?

Just like a parking ticket, you cannot transfer this contract to anyone else without our permission. This contract stays in place and need not be renewed. If for some reason one part of this contract becomes invalid or unenforceable, the remaining parts of it remain in place.

Although the language is simple, the intentions are serious and this contract is a legal document under exclusive jurisdiction of US courts.

All parties should sign below and keep a copy for their own records.
