Fish (contract template) to work with foreigners for software development?

Question

Law in IT

We need a contract template (providing services for software development) to work with foreigners. I have absolutely no experience in drafting such contracts, so I'm looking for the most concise (2-3 pages is ideal) template. The template should indicate the place where you can write down the exact list of services performed in order to save yourself from drawing up acts (if possible and legal). The contract should state that it is considered fulfilled after the payment of the invoice (again, if it is possible and legal). Last question on dates. Is it possible to not specify the term of performance in the contract? That is, the invoice is paid - the contract is fulfilled and I fulfilled all obligations under the contract.
PS The contract must be in Russian, the division into two columns and the translation will be done by myself.

Answer 1

if an individual entrepreneur and a bank, you will have to specify both the amounts and dates
