I'm new to contract law and have a scenario where I need to draft a digital contract to collect payment as soon as contract is signed but remaining terms of the contract will become effective some time in future.
From what I have read so far, it looks like a contract can have different contract execution date (signature date) and I can introduce an effective date clause which can mention the date on which terms will go into effect. Is there a commonly used clause that I can use to enforce collection of payments before the effective date? What would be a correct way to draft such a contract? Any examples would be appreciated.
