Try the below

=SUMIF(A2:A2966,$K$1 & "*",I2:I2966)

The above formula will sum the values in I2:I2966 if the first characters in
A2:A2966 are same as what is specified in cell K1. This works only for text
strings.

or should it be
=SUMIF(LEFT(A2:A2966;9);$K$1;I2:I2966)
I'm using this formula for as you can see nearly 3000 rows, is there another
way of doing it?
