Project development sequence?

Question

1C

Good day to all, I ask knowledgeable advice on the implementation of the planned project: Implementation is planned in several stages:
1. Collection of users and communication with them (task: maximum attractiveness and convenience for users, eliminating the risks from heavy loads and security)
2. Monetization of the collected audience (task: maximum convenience for users and automation of work and control of employees, eliminating risks from heavy loads and safety)
General task: When developing a project, supplement existing developments and tools with the least additions or complete replacement of early developments and tools. I will try to explain: To implement the first stage, I (who know little about developments and tools) are considering a telegram bot.
When moving to the second stage, I am considering supplementing with 1C solutions. And since in the first stage, it is already necessary to implement the collection and storage of user data, and 1C does not work with all DBMS, then from the first stage it is necessary to select the required DBMS so that at the second stage you do not change the DBMS and do not transfer the existing database.
I will describe the process: Subject, auto. Car enthusiasts can get a selection of prices for the service, goods for their car, as well as invite friends, receiving bonuses for this.
At the second stage, motorists will additionally be able to buy or order a service.
But I repeat, the implementation of the first stage should be as budget-friendly as possible and at the same time convenient and pleasant for the user. at the first stage, there will be no monetization, and if a sufficient number of users are not recruited, there will be no point in the further development of the project. But if everything goes well in the first stage, then in the second stage you will need tools for communicating with users, working with orders, sales, delivery, production, accounting and control, management of all processes.
I hope I was able to outline the plans, but if something is not clear, I am ready to answer your questions.

Answer 1

Why do we need all this?
For tz - too general words
For the plan - similar to
1s and postgres v8.1c.ru/overview/Term_000000133.htm

Answer 2

and 1C does not work with all DBMS

with almost all
v8.1c.ru/overview/Term_000000795.htm
v8.1c.ru/overview/Term_000000581.htm
decide why you need 1C.

Answer 3

At the beginning of the second stage, you will need tools for the work of sales managers; work with clients, search for new ones, execution and support of the execution of orders, as well as for setting and monitoring the execution of tasks and all the work of managers. I think CRM is more suitable, namely 1C CRM.
