What is the name of the contract?

Question

Business Informatics

Until recently, he worked in another company as a co-founder. Now own company, recently opened. I conclude an agreement with one company, quite large. Confuses one moment. Working in the old company, we called the contract simply starting with one. In this case, this is the first contract as a new company, so somehow I don’t want to start - Contract for the development of site No. 1. Because the first and would not like others, logically, understood what the contract was. Maybe as an option to come up with some kind of alphanumeric code? Something in the style of RS-01/0615 where RS is the development of the site, 01 is the first contract in this month, 0615 is the month, year. I mean, it won’t be strange for the customer?)
In fact, there are no legal rules for the name of the contract, and these are office work rules, so I would like to adhere to some rules.

Answer 1

Agreement for the development of the site No. RS-2015/06-1.
It’s easier to navigate this way, it will immediately look like a year, then a month and the contract number itself.
The client does not care about the name at all, unless the client in the company has adopted its own addressing agreement, but such are found in 1/100.

Answer 2

Agreement No. 1

Answer 3

There are no numbering standards, come up with your own convenient one. Make the pattern simpler. Entering monthly numbering from 1 is inconvenient. It will be more convenient to enter the beginning of numbering from the new year.
