Is there a free CRM with field settings?

Question

CRM

Now a lot of divorced CRM. Each is unique in its own way and each has its drawbacks. There are a lot of reviews written on them. But sometimes in the reviews they do not write the main thing, the little things that are important in certain areas of application. For example, adding custom fields to products and services, etc.
For example, we have a contract with a company and under it we sell a service or product to the company. CRM already has a certain set of fields, for example, how to look at the link on the screen

But are there any systems where you can add your own fields? For example, my costs and profits from the project, etc.

Answer 1

In Feng Office you can customize everything you need and how you need it.

Moreover, the field settings are very flexible, an order of magnitude more flexible than, say, in the same Bitrix24.
These fields can be configured for any entities. There are many types of fields and you can expand as you like.
And the fields lend themselves to conditional logic. You can make some fields appear or hide depending on the completion of others. Very convenient and useful when setting up the system.

Answer 4

I maintain a client base .
You can put the free version on your hosting or computer and use it indefinitely until you hit the limit of 500 records (in any table, old records can be archived or exported). You can add your fields, your tables, your filters, your connections and calculations, and finish the functionality and interface using php & js (if necessary). The design is not modern, but in terms of flexibility and adjustment of functionality to the business of this CRM, there is no equal even in the free version. And the paid one is cheaper than analogues.
