AI Client Portal Builder for Sign Companies
A client portal for sign companies, built from a description. Logins, per-client data, file uploads and a staff side for you — all with a Postgres database and published to a URL you control.
Who it's for
Teams at sign companies who need clients to see their own information — and only their own — without building auth from scratch.
What you can build
- A login where each customer sees only their own records
- Documents and files you upload, available to download
- Status or progress on shop signage and vehicle graphics
- A message thread between the customer and your team
- A staff view listing every customer and their history
How sign companies work
A sign company turns a customer's logo into something bolted to a building or wrapped around a van. Each job moves through an inquiry, a site survey, artwork proofs, planning or landlord approval where needed, production on the printer, router or vinyl plotter, and a scheduled install that depends on weather, access equipment and the customer being on site. Quotes live in email, proofs in a shared drive and install dates on a whiteboard. Software helps by keeping every stage of each job, and its sign-offs, in one record.
What client portal for Sign Companies has to handle
- Customers should see artwork proofs and approve or request changes in writing, with each version kept.
- The portal should show job status, from survey done and proof approved to in production and installed.
- Survey photos, measurements and final install photos belong on the job for the customer to download.
- Multi-site customers need to see all of their locations and the status of each sign.
A tip for sign companies
Never go to print without a written proof approval tied to a specific version. Spelling mistakes and wrong phone numbers on a finished sign are expensive, and a portal that records who approved which version and when settles disputes before they start.
A prompt to start from
Build a client portal for a sign company. Customers log in and see only their own records: customer name, sign type, dimensions and install date, files we uploaded for them, and the status of the work we are doing for them. Add a message thread per client and a staff area where our team can see everyone, add records, upload files and reply. Use a database with proper per-user access.
Questions
Can customers approve artwork proofs in the portal?
Yes. Ask for proof uploads with an approve or request-changes button, and a record of each version and who approved it.
How does login work?
Ask for accounts and Mythex builds sign-in into the app. Each published app has its own users and its own data, separate from your Mythex account.
Can clients only see their own data?
Yes, and it is worth saying out loud in the prompt. Mythex scopes each query to the signed-in user, so one client cannot open another's records by changing a URL.
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.
