The setup phase, usually one to two weeks, in which the integration reads everything and writes nothing. The panel shows side by side what it would have written and what each channel currently holds, and the differences become the list you work through: mismatched products, missing barcodes, a channel still being updated by an old tool. Because nothing is written, none of those errors touches live sales. It is the cheapest place to find them, and the step most often skipped under time pressure. See testing an integration in shadow mode.
See it before we explain it.
We will send you login details for a working copy of the panel; explore it yourself, then let’s talk.
