123 Street Name, Ste 987

Sampletown, XY 50001

Thank you for considering Your Company to build your web app. This proposal covers what we heard, how we'll get from idea to launch, what it will cost, and three ways to work together.

 

What We Heard

[Summarize the product, for example: a customer portal where your clients book services, track job progress, and pay invoices, replacing a mix of email, spreadsheets, and phone calls.]

 

How We Work

1. Discovery and prototype (3 weeks). Workshops with your team and a few users, user flows, and a clickable prototype of the key screens. It ends with a technical plan and a confirmed estimate for the MVP.

 

2. MVP in two-week sprints (about 12 weeks). Each sprint starts with planning, where you choose the most important features from the backlog, and ends with a demo on a staging site you can try yourself.

 

3. Testing and launch (2 weeks). Testing across browsers and devices, security and performance checks, and a launch to your production hosting.

 

4. Support. After launch, we fix defects in our work for 30 days at no charge. Ongoing improvements are available on a monthly retainer.

 

What You Provide

  • A product owner who can make decisions and attend sprint planning and demos
  • Access to a few customers or users for discovery and testing
  • Content, brand guidelines, and any existing systems we'll connect to

Ways to work together

Discovery is a fixed fee. Development is priced by the sprint, so you decide how far to take the MVP. Each option includes everything in the one before it.

Hosting and Third-Party Services

Hosting, databases, email delivery, payment processing, and other third-party services are set up in your name and paid by you directly. For an MVP, we expect these to cost about $150 to $400 a month at launch, depending on usage. We'll confirm the services and costs in the technical plan.

 

Changing Priorities

The backlog is yours to reorder at every sprint planning. Swapping one feature for another of similar size costs nothing extra. If the MVP needs more sprints than planned, we'll agree on them with you before starting. Other work outside this proposal is billed at $125 per hour, quoted before we begin.

 

Ownership

Once paid in full, you own the code we write for your app and the designs we create for it. Open-source and third-party components remain under their own licenses. We keep our general tools and know-how, and grant you a perpetual license to use any of our own code included in your app.

 

Payment Terms

50% of the discovery fee is due on signing and 50% on delivery of the prototype and plan. Each development sprint is invoiced when it starts. Testing and launch are invoiced at launch, and the support retainer at the start of each month. Invoices are due within 15 days.

 

Ending the Project

Either party may end the project with 14 days' written notice. You pay for work completed to that date, and we hand over the code and designs you've paid for.

 

Acceptance

Choose an option and sign below to accept this proposal. We'll schedule your first discovery workshop within two weeks.
