I am not an every size project fits me type salesperson.
A large distributor that employs estimators, salespeople, detailers, project managers and warehouse staff should be able to excel at a project with 600 openings. That same project would likely cause a nervous breakdown to a small distributor where the salesperson wears each of those hats at every moment. Another reason to really spend time making sure a project is the right fit, don’t over extend! Financially 600 openings = 600 frames and doors, 1800 hinges and so much more, that is a lot of monetary output with payment running at 45-60 days.
Personally I like to keep my customer service level high so I always get a phone call for the re-order. You know the next job the boss is always asking about. My own rule of 100 and under works best for me. I typically don’t bid a project with over 100 openings unless it is for a very good customer and the count is close.
I just closed a 105 opening project which makes me excited and terrified all at the same time. With my existing work load plus the new project I won’t bid a lot of work to make sure I meet the material and time requirements of the jobs. In the meantime I will balance a lot of hats and be counting a lot of hinges!
