Yes.
You need to verify that data values for several fields are exactly same in Xero and Service Geeni.
For example the spelling of Branch, Customer and/or Supplier need to be exactly identical to avoid any duplicity. Otherwise it may lead to confusion.
Consider a scenario where the customer name in Xero is βAllan Fairbrother & Co.β and the same customer exits in the name βAllan Fairbrother & Companyβ in Service Geeni.
As Service Geeni performs an automatic sync of Customers from Xero to Service Geeni and the customer profile is also imported they could become a duplicate or additional (if the names are not identical).
