amoCRM
When you close a deal in amoCRM, a separate task will appear in Pyrus automatically.
In this task, you can do everything you need to on the closed deal: connect your colleagues, and provide all the necessary documents. This is convenient if you need to transfer sales orders from the sales department using amoCRM to the delivery, installation masters, or to the warehouse.
Additionally contacts from amoCRM are synchronized so you don't have to manually enter them in Pyrus. Users will be able to select a client from the directory when filling out applications in Pyrus.
