Switching from J3 POS
Keep the power of a system built for your business. Run it the modern way.
J3 was built for the store of the 90s. Rundoo is built for the hardware, lumber, and building-supply store of the 2020s: the same industry-specific approach, in a modern web-based system.

Why stores switch
Three reasons stores make the move
Run your store from anywhere.
Sales, margin, and stock on your phone or your desk, with the same numbers at both. See the Staff App.
Find what you need fast.
Search products by what they are, not by SKU or UPC. Keep moving. See the Web App & POS.
Ask Dooey. Don’t click around.
Ask for stock, a report, or a draft replenishment order in plain English. A person reviews it. See Dooey.
Feature comparison
The same daily jobs. A much more modern way to do them.

Data migration
What we bring over from J3 POS
Our data team maps your J3 exports into Rundoo and reviews them with you before go-live. Here is what comes over.
Bring the data you need. Leave the clutter.
J3 product files can contain years of stocked, non-stock, inactive, and distributor-catalog items. We review what should actually come over before go-live.
