estimate drift (advice appreciated)
Without going into way too many details, we are working with a vendor is generally great, trustworthy, etc. But, and this is a big but, now a businessman. He’s consistently been off on quotes and often comes back with prices about 30% higher than estimate.
I think we are still getting great value but its making us not want to work with this vendor.
How much drift/overage is acceptable?
Thanks,
FF
