Square Clover Integration: Keep Both Registers in Sync

This is the pair where both sides are counters. There is no storefront acting as the obvious source of truth, so the question is not which platform to trust but where the count should live. QuickSync holds it between them and corrects each side from the other, which means a sale on the Square register lowers what Clover will let you sell, and a Clover sale does the same to Square.

Shops end up here for ordinary reasons. A second site opened with different hardware, a business bought with its till already in place, a market stall running Square while the shop runs Clover. In each case the stock is one pool and the two systems have no idea the other exists. Left alone they part company within a weekend, and you find out with a customer waiting.

Both sides announce their changes to us as they happen, so nothing here is on a timer. That matters most when the same item can sell in two rooms in the same minute, which is precisely the situation two tills create. A count that moves as each sale is rung through is the difference between telling the second customer no and selling them something you do not have.

This is the gap to know about before you start posting orders taken over the counter. Square has no field for a tracking number and neither does Clover, so there is nowhere for us to write one on either side. The number stays visible in QuickSync, which on this pair is the only place that holds it, and that is a limit of the two platforms rather than a step we skipped.

For most till sales it is irrelevant, because the customer leaves with the item in a bag. It matters when someone orders at the counter for delivery later, or when a member of staff works out of one register and expects the shipping detail to sit on the sale. Point them at QuickSync, and settle that habit early rather than during a week when parcels are going out.

The other number to know is SKU length. Items pair up by SKU, and Square is the shorter side at 80 characters against Clover’s 100. Eighty is roomy for a till code, so most shops never come near it, but anything over the line is truncated on the way to Square and then stops lining up with the item it belongs to. One look at your longest codes is enough.
