If an invoice description is changed in Xero will it sync and retrospectively update the description already in ScaleXP?

All data is imported into ScaleXP daily (at 7am GMT) including all customer invoices and supplier bills.  Any modification to a bill or invoice will be detected by ScaleXP, including retrospective modifications.

This is designed to ensure that the systems are fully in sync.

If you have modified the spreading period in ScaleXP, the system will import the latest description.  Your manual changes will not be overwritten.  

In essence, there is a hierarchy for modifications to the dates: 

• If you have modified the invoice spreading time period or dates in ScaleXP, these will always be retained, even if the invoice line description is changed in the accounting system.
• If you have never modified the invoice dates in ScaleXP, the latest description from the accounting system will be used to spread the invoices.  

All other invoices or bill changes will update ScaleXP including changes to the tax rates, the invoiced amount or the supplier name.   

Hint:  Our top hint is to decide upfront where you will track modifications and to be consistent.  Making some changes in ScaleXP and others in the accounting system is likely to lead to confusion.
