We have a competitor, POS Solutions, that has published a claim of constraints, barriers, on the Xero POS software link.
For the record, we note that no such constraints or barriers have been experienced by us in any of our retail businesses or in any Tower Systems client business using our direct Xero interface.
Footnote: the challenges for the competitor could be due to how they connect to Xero. Tower Systems is a Xero partner, listed on the Xero website. The competitor is not. They may be going through anther party.
