What do I need to set up if I'm switching POS provider?

Because POS databases can't be merged, you'll need a new Loaded company for the new POS. In the new account, set up your staff roles, staff members, pay codes and POS links, plus suppliers, delivery details, custom units, menus, order templates, supplier tenders and stocktake templates. You'll also need to invite your users again with the right permissions, and share your stock items and recipes across from the old account.
