Common questions about inventory sync
What does QuickSync charge for?
Catalogue size and connected shops. Your plan price covers two shops; every shop after that adds the plan price again. Order volume never changes the bill. Work the numbers on the pricing calculator.
How many shops can I connect?
Eight is the hard cap on every plan, Lite through Ultra+. Thirteen channels are available; which eight you pick is up to you. Most sellers connect two or three.
Is inventory sync instant on every channel?
Writes to a channel are fast everywhere. Finding out a channel changed something itself is instant on most channels. eBay is checked every two minutes, Etsy stock every two minutes and orders every five, Squarespace stock every two minutes, and Xero items every two minutes.
Where does the 4.9 rating come from?
The summed published rating across our Shopify App Store listings (3,200+ reviews across the R.I.T.N.S. listings). Comparison pages cite it in visible copy only, never as AggregateRating schema.
Price your catalogue, then pick the plan
Two shops are included in the base price. The calculator shows the bill before you connect a third.
