How to draw up an offer agreement for the provision of services in an online store selling ready-made orders?

Question

Law in IT

Hello!
I get orders from various sources and topics: audio, video, WP plugins, etc.. to summarize - digital products. I decided to implement them on my website, with the connection of YaDeneg
Yumanya says that there should be an offer contract for the provision of services .. how to draw it up correctly if most of the products are executed under other contracts, those. tasks, etc., and are actually already the result of the service rendered?
In the legal part, not as strong as I would like ..
