Try it out for yourself

Before PieSync, syncing our data to a CRM was more of a hassle than an advantage. We needed to keep the categories we were using in Outlook. That was the base of our internal organization and no other cloud integration software was offering that possibility. Intelligent Syncing makes PieSync the most advanced sync engine out there!

I use Freshbooks for invoicing and SharpSpring for marketing. I was looking for a way to get my customer information from Freshbooks and into Sharpspring and PieSync does that perfectly. I also use PieSync to add customer details to my email marketing apps, I even sync customer contacts to my phone via iCloud. It works in all directions, so even if I am out of the office and I meet a new contact, I add them in my phone and PieSync syncs them to my other systems instantly. I’m using a variety of software apps because I want to have best-of-breed apps running my business. Luckily I can rely on PieSync’s Intelligent Syncing to update customer details across all of these systems.
