$150 per hour is on the low end for good SAP consultants. We were paying $300 per hour for some InfoSys SAP HANA people, and even independents were around $200+.

If they're doing anything beyond vanilla consulting work with SAP then I doubt they're using cheaper offshore talent. Or maybe they are and that's why this project has failed so spectacularly. (Note: I'm not saying all offshore talent is hot garbage, I'm saying the cheap talent is hot garbage, especially SAP consultants).

True, but not all 100 of them are that level or being used full time for years would they ?

I think that price is a little inflated. 1200€ a day for a freelancer maybe, but the "normal" consultants will cost no more than 800-900€ a day because of blanket orders, etc.

Not sure whom Lidl hired for their SAP project, if they hired from one of the big 'consultancies' which I assume, cost would be easily >2000 EUR/day.

I work with big consultancies, and they don't charge >2000€ a day for SAP developers, I know that for sure ;)

$1200 is not realistic price for SAP consultants in Germany.

One way to calculate: 7years × 365days × 2k/day × 100 "experts" = 500m

People don't tend to work every day in a week, and there are holidays etc.
