About Aislekit

Aislekit is a one person software business. I write the code, I answer the mail, and I decide what gets built next. There is no queue and no ticket number: an email to aislekit@gmail.com reaches the person who wrote the thing you are asking about, and I answer within one business day.

What I make

One app, Aislekit PO Label Print. It prints barcode labels for the stock you are receiving: from a Shopify inventory transfer, from the purchase order file your supplier sent you, or from products you pick by hand. It lays them out for Dymo, Zebra, Brother and Avery stock, gives you a PDF you can print anywhere, and writes ZPL for Zebra printers. The interface is translated into every language the Shopify admin offers.

What it is not allowed to do

The app asks Shopify for two permissions and both are read only: your products and your inventory transfers. It cannot edit a product, change a price, write a barcode, touch an order, or see anything at all about your customers, because it never asked for permission to. You can check that yourself on the install screen before you click Install, and again under Settings, Apps and sales channels in your admin.

That limit is a choice and it costs me features. Most apps in this category ask for write access so they can generate barcodes into your catalogue. I would rather print a label off the SKU you already have than hold the keys to your product data.

Why it exists

Stocky, the app that printed purchase order labels for years, stopped working on 1 September 2026. Retailers who were receiving a delivery, printing a shelf label and moving on suddenly had no way to do the middle step. I built the middle step.

What it costs

Free for up to 750 labels a month, with no card and no trial clock. Pro is $12/month or $120/year with a 30 day free trial, and it adds custom label sizes and the Zebra ZPL export. Billing runs through Shopify, so it appears on your Shopify invoice and you cancel it from your own admin without asking me.

Where things are

The app is on the Shopify App Store. What it stores about your shop, how long it keeps it, and how to have all of it deleted are in the privacy policy. If you are here because Stocky went dark, the exit checklist is the page you want.
