MerchUI

The parts of running a store that nobody enjoys.

Artwork arriving across six emails. Four hundred prices edited one at a time. Layouts done by hand at eleven at night. MerchUI builds tools for those jobs, and takes on the store work that does not fit inside an app.

Three ways this helps

Most stores need a mix. A tool for the repeating job, a pair of hands for the one-off, and someone to look at the whole thing once a year and say what is costing you orders.

Tools you install

Apps that take one job off your desk permanently. Layout, proofs, customer file uploads, bulk edits. Flat monthly price, no cut of what you sell.

Store work we take on

Shopify builds, Etsy migrations, and the fixes a store needs after a few years of being added to. Quoted up front, handed over when done.

What we take on

A second opinion

Someone who sells on the same platforms going through your store and saying plainly what is working, what is not, and what is not worth changing.

Ask for a look

Tools

One job each. Where a tool is not finished, the card says so, because something you cannot install is not a product.

File Uploader

For Stores selling custom and personalised products

The customer attaches their own design on the product page, before they pay, and the file arrives on the order line it belongs to.

  • An upload field on the product page, not a link sent afterwards
  • The file on the Shopify order itself, not just in an app
  • Large files, size and type checked before the order goes through

Why merchants come here

Written from inside the job

Every tool here replaced something being done by hand in a real shop. The awkward parts got found by the person who had to live with them, not in a planning document.

Flat price, not a cut of orders

Charging a percentage of each order is common and looks harmless until a store gets busy. A good month should not cost more than a quiet one.

You keep what you paid for

Files, code and accounts are handed over. Nothing is held back to make leaving harder, and uninstalling returns your data rather than keeping it.

Common questions

Do I need a developer to use your tools?

No. They install from the Shopify App Store and configure themselves. Where something goes on a product page, it is a block you drag into place in the theme editor, with no code pasted anywhere.

I sell on Etsy, not Shopify. Can you help?

Yes, on the store work side. Listing migration, bulk listing creation and keeping two storefronts in step are all jobs we take on. The apps themselves are Shopify only, since that is where they install.

How much does store work cost?

It is quoted per job, in writing, before anything starts. There is no hourly meter running in the background, and the first conversation is free.

Are the tools that say "in development" available?

Not yet. They run in the shop they were written for, which is not the same as being installable. Ask to be told when one ships and you will hear the day it does.

Who is behind this?

A web developer who also runs a DTF print shop in Orange County. Which is why the first tools are the ones a print shop needs. More about that.

Whether it turns into a tool, a fix to your store, or a note that you already had it right, the first conversation costs nothing.
