AI Quote and Estimate App Builder for Freelance Designers

Quotes for freelance designers in one place instead of scattered across email drafts. Describe your services and rates; Mythex builds the app that turns them into clear, numbered quotes your clients can approve online.

Who it's for

Owners and estimators at freelance designers who want every quote numbered, saved and easy to find when the client calls back.

What you can build

  • A price list of brand identity, web design and design retainers you can add to any quote
  • Line items with quantities, your rates, discounts and tax
  • A shareable quote page the customer can accept or decline
  • A list of every quote with its status: draft, sent, accepted, expired
  • Turning an accepted quote into a job or an invoice

How freelance designers work

A freelance designer runs a one-person studio: finding clients, writing proposals, doing the design work, collecting feedback and chasing invoices. Work often comes in waves, with a few large branding or website projects alongside small retainers. Clients arrive through referrals, portfolio sites and social media. Proposals sit in a document, feedback comes through email comments and messages, files live in cloud folders, and invoices are in a separate app. Software helps where each project has one place for scope, revisions and payment.

What quote & estimate app for Freelance Designers has to handle

  • Project scope, deliverables and timeline written clearly.
  • Revision rounds included and extra rounds priced.
  • Usage rights and licensing terms.
  • Options for different packages.

A tip for freelance designers

Spell out what is not included in every proposal. Most disputes come from assumptions, such as the client expecting a full brand guideline when you quoted for a logo.

A prompt to start from

Build a quote and estimate app for a freelance design business. Keep a price list of services such as brand identity, web design, design retainers and consultations with a default rate. Let me create a quote for a customer with client name, project and deliverable, add line items with quantity, rate and discount, and see a total with tax. Give each quote a number and a shareable page where the customer can accept or decline it, and show all quotes in a list with status and value. Use a database and add a login for staff.

Questions

Can clients accept a proposal online?

Yes. Ask for an accept button that records the date and version, and turns it into a project. Deposit collection needs a payment provider you connect yourself.

Can a customer accept a quote online?

Yes. Each quote gets its own page with an accept and decline button, and the status updates in your list. Ask Mythex to email you when a quote is accepted.

Can an accepted quote become an invoice?

Ask for it in chat: Mythex adds a button that copies an accepted quote's line items into an invoice, so clients are billed exactly what they agreed to.

Do I need to know how to code?

No. You describe what you want in plain language and Mythex writes the code, shows a live preview, and lets you change things by chatting. The code editor and terminal are there if you ever want them.

Do I have to explain my business every time?

No. Mythex remembers who you are and how you work across every project, and follows the standing notes you set for a project, so you are not re-briefing it in each new chat. You can read, edit or switch all of it off.

How much does it cost?

There is a Free plan with daily credits, enough to build and publish a first version. Pro is $25/month and adds full code editing, GitHub export, custom domains, and credit top-ups.
