The above is the title of a document that describes two things. One is signing procedures for memoranda on provision of products of a company called ABC (to another company). The other is procedures for delivery of the products.
Q1: Should I say "Signature on" instead of "Signing"?No. In fact, I think "signing memorandum" is a standard business term.
Q2: Should I say "delivering" because I used "ing" for "Signing"? Is it necessary to match the form of two verbs, "sign" and "deliver"?No, these two words are grammatically unrelated (see above: signing is an adjective). If you separate out the two things that the document refers to, it becomes easier:- Signing memorandum on provision of ABC's products and [signing memorandum on] delivery of the products.
One last thing: If there are two (2) memoranda, then you should probably say:- Signing memoranda on provision of ABC's products and on delivery of the products.
