redo identity column

I have a new set of tables for invoicing and we are inserting invoices manually from word and excel files. Right noow we are just entering them as we get them and will need to sort them by date and then have the new invoice numbers in that sequence.

How would I do that?

you can add one new column with identity and turn if off.

insert the data using below query

insert into table_name (your_id_col)
SELECT ROW_NUMBER() OVER (ORDER BY date_column) AS Id FROM yourTable

and once this is done, turn on rhe identity

Create the table with IDENTITY column COL1 and then run the query to insert into the same:
i.e. INSERT INTO NEW_TABLE(COL2, COL3) SELECT COL2, COL3 FROM YOUR_MANUAL_TABLE ORDER BY MANUAL_INVOICE_DATE ASC
