Need a very simple CRM system, is there such a thing?

Question

Helpdesk

Recommend a simple CRM system or a helpdesk system or an application processing system. I don’t know how to call it correctly, so don’t hit me)
The bottom line is that there are several landings and a small online store that sell several products. It is necessary to collect all applications from the feedback in one place. Also, the purchase of goods is made by mail. i.e., the administrator will receive an email with a link to the product and the contact details of the buyer.
It is necessary to somehow separate ordinary letters (feedback) and letters of order.
Orders for: new arrival, in process, sold out. i.e. 3-4 positions will be enough.
It is desirable, but not critical, that you need a customer base as well as their notification of the status of the application.
Also division by design. i.e. so that I or the manager understand from which landing the application was received.
Preferably free. Processing will be done by one person. In the future maybe two but definitely not more.
Of all the variety that I managed to find, the main problem is that everyone has a very overloaded interface. I would like something simple. If there is such a thing, of course :)

Answer 1

It is necessary to connect REST to all landing pages from the central service for collecting and viewing applications.
In the meantime, everything is done through your ass. (roughly - yes, but you can trust me that this is true) Do you
want a normal organization of the application process? I can create an architecture for your business process. Inexpensive, but not free.

Answer 2

Yes, and not alone. Bitrix24 is the most famous platform among the CIS countries today, but it is starting to lose ground precisely because of its complexity. And the business processes themselves require simple actions for a clear transparency of the picture. For modeling and managing business processes, it is best to use specialized software, for example, an intelligent platform - https://www.terrasoft.ru/studio . The system will allow modeling processes of any complexity. And you, in turn, will be able to ensure the comfort of use by involving BPMN notation in analytics.
