What it can't give us

K-Series and O-Series are supported. X-Series is on the list and isn't connected yet.
Multi-currency groups are reported per location in local currency; there is no consolidated conversion.
Lightspeed's API rate limits mean the initial history read can take a few hours on a busy multi-site account.
