Integrations
The times are over when it might be advantageous to choose just one supplier, because it all hung together. Most people have learned that in practice it may not be that easy anyway and that you may be overly locked in to the chosen supplier.
We believe that you should have the freedom to choose the ERP system that best suits your needs. Similarly for telephony, mail, maybe time tracking and of course CRM. That's why we concentrate on providing a really good CRM system that can easily integrate into a wide variety of systems.
See more about some of these integrations here. Note that it has also become easier to build integrations - e.g. using Zapier. What used to take weeks or months usually takes hours or days.
