The simplest way I can think of is to load the data from the Excel file into a Work Table and then write a query to Add/modify/delete. To delete the following, and similar code for Insertions and updates
FROM YourRealTable y 
	SELECT * FROM YourWorkTable w
	WHERE w.customerid = y.customerid
	AND w.status = 'Delete'
You can use SSIS to insert and to run the update queries.

in ssis you can use conditional task to define outputs based on status column value in dataflow task and write corresponding logic (insert/update/delete) in relevant output branches. Use OLEDB command for update and delete and then OLEDB destination for insert.
If number of rows is really huge, consider doing update in update/delete branches to set bit value to indicate records to be deleted/updated and then follow up with execute sql tasks in control to do batch update and deletes. Also for insert set fast load option for OLEDB destination
