I would put all projects other than clearing up AP issues with suppliers on hold indefinitely in order to get them shipping again. 80% of my sales so far this year have yet to ship out. There is no repeat or referral business here. The days are spent "putting out fires" and, since you can't sell what you don't have, we turn away more leads than we close, simply because we know we can't deliver.
Change the focus to taking care of a smaller customer base and winning their business one sale at a time. Impress them and invite them to return. Less Google AdWords and more word-of-mouth.
