All very good points thanks! They are 50% of our business. The owner is over 90 yrs old and very old school mentality. His Grandson is in charge of orders most of the time. He actually called me while I was pricing this order out for his grandfather and bit my head off for not placing the order right away. He said he doesn't care about pinching pennies like is grandfather. He wants things done when he asks. These situations aren't worth 100% markup most days.
Thanks again for the input. You all have a lot of useful insight and I will definitely use it going forward with this customer.
Hopefully, this little scare is a good lesson about having such a huge portion of your revenue based on one client and one with which so little room for maneuverability and added value on your part is involved.
This relationship has reduced yourself to an order taker and money exchanger at the whim of this client who now knows everything they need to do to pull the carpet out from under you at any time. Your company's dependency on this one client is precarious at best.
I managed a graphics department for a good sized trade show/exhibit company for about five years and about 70% of our revenue came from Nike and a tech company named Tektronix. Nike was as demanding, particular and spontaneous as a client could be AND took 180 days to pay. Great money, steady work, really interesting, fun projects shipped all over the world but our employer was constantly chasing the money stream to maintain cash flow. We'd often be thrust into projects on a day or two notice that triggered 60 hour weeks for over a month at a time but most being quoted at normal delivery timetables. Nike dangles their work over the open mouths of any vendor they think will bite and it is never a super advantageous arrangement for the vendor. Wal-Mart has made itself into the world's largest retailer doing the same thing.
Without adding any real value or labor to the transactions including even delivering the faces to them, there is little or no incentive to use you unless the wholesale price you receive is so low enough below what they can get them for retail including your markup.
That is not a sustainable business model moving forward.
