Quickbooks Online to Zoho Books Migration

Quickbooks Online to Zoho Books Migration

I want to migrate all company accounting records from Quickbooks Online, version Simple Start, to Zoho Books.
Quickbooks Online was only used to keep track of bank transactions and to create reports for tax purposes. 

Records contain:
~1100 bank transactions, dating back to 2016,
~80 Vendor & ~30 Customer records
-Chart of Accounts with standard accounting categories such as bank account, assets, income, expense, etc..

No AR, AP, or Inventory records.

What is involved with this type of migration?

thx much, Uwe.
