I have worked for LSI for a long time and never had problems with them. Yes it is true that they want a flat rate to include copies, however I have many clients that want that as well.

And yes occasionally a "pending order" doesn't get paid, then I bill them for it on the next billing cycle and they pay it. Do you have a relationship with anyone in their accounting department? If not call and ask for Debbie, she's great.

Regarding LSI North wanting a copy of the prior owner's acquisition deed, or a full copy of the PMM  did you call and change your prices when this type of order came out?

And yes LSI North will sometimes send an order in the afternoon wanting it back the same day, however thats what their website is for, so you can put status in their system for the orders they send you.

I believe in tons of communication with my clients, that has always been successful for me because I believe that communication can solve any problem.

I personally am tired of hearing about the "big bad LSI," I love working for them and I think they are a great client and they pay, you send an invoice and 2-3 weeks later you have a check.

I think with a few phone calls you could solve all of the "problems" you are having.
