Square Etsy integration that keeps the register and the marketplace in step

Etsy allows two option types on a listing. Square will happily hold a product that varies by size, colour and material, and that product cannot cross to Etsy in the same shape: two of those have to be combined into one option, or the product has to become more than one listing. Neither is difficult, but it is a decision about your catalogue rather than a setting we can flip for you.

The second rule bites straight after the first. If you split a product across two Etsy listings and leave the same SKU on both, Etsy flags them as ‘Multiple same SKU’ and we keep sync off for those listings. That is a deliberate stop rather than a failure: with one SKU pointing at two listings there is no honest way to decide which count belongs where. Give each listing its own SKU and they start syncing.

Items pair by SKU, and Etsy is the shorter of the two at 32 characters against Square’s 80. A SKU that a Square till accepts without complaint can arrive at Etsy truncated, and a truncated SKU stops matching the item it came from. Nothing errors, so you notice when a count drifts rather than when it breaks. Sorting your catalogue by SKU length takes a minute and settles it.

Etsy cannot announce a sale to us, so we look on a schedule instead: orders every five minutes and stock every two. That is the window to plan around on the Etsy side, and no tool can shorten it from the outside. If you are selling the last of something at a market while the same listing is live on Etsy, that is exactly where a short window matters, and a small buffer on one-off pieces costs less than an apology.

One gap to know about: Square keeps no place for a tracking number, so we have nothing to write into. Post an order that started at the till and the tracking sits in QuickSync rather than on the Square sale. Most sales at a counter leave with the customer and never need one, so this only matters if you take orders in person for posting later.
