How much would you charge to store small inventory and handle shipping of items weekly for a company that will basically add my designs and products to their webstore and I will bill them weekly after I ship out the products? I am already charging them for engraving, and the website would charge a shipping and handling fee, but would I just raise the cost of my product price to them for each item or would I add that on somewhere else so it is not taxable somehow? It would cover the cost of my packaging, going to post office and packaging, buying boxes and addressing, labeling, tracking orders and possibly corresponding with customers to verify custom information.
Also what is the best way to charge me to use my brothers laser. It is not his main business, he bought to use to make extra cash on the side and to save himself the money it cost to get his parts he makes engraved with his business logo. I will be using it often for my business, we have thought about a percentage of sales? per item? or per minute? But If I am using laser for 5 mins and I there packing and changing design, I dont want to squabble about it. or set a timer every time I use laser. But I may only need to use the laser for 1 hour total and be in his shop while he is doing other work for a total of 5 hours. What is the most fair way to handle it?
Thanks!
