Christine: you are AMAZING!!!  Thank you so much for your help, not only today but for your ongoing support.  We are so fortunate to be working with you and the entire Dillner's team!

I don’t say this often enough, but I absolutely LOVE your suite of software!  We’re certainly cheerleaders for FCAS! I think I’d have a mutiny on my hands if I ever wanted to change. I use you A/R and I absolutely love it! It doesn’t take that much time to enter my tax prep invoices as I prepare them. I then use the A/R to produce my bank deposits. I have my payroll person, enter all the payroll billing at the end of the month. I simply run my recurring and print my bills. Then I import the file into FCAS along with P/R. It doesn’t get any easier than that! Before changing to the A/R, I would find excuses to not process my own account during tax season. Now, I have my financials complete on the last day of the month…without fail. I love it!!!  I want to thank everyone there for doing a remarkable job and being there when we need you…..which is quite often.

I've used Dillner's Write Up since 2003. I absolutely love it. I made the decision to go to it over another Write Up program and I've never looked back. I use CSI for all other applications and I get 98% of the interface with a much better product. QuickBooks importing is significantly better and this was a huge aspect of my client base so this was very important. Support has been outstanding and we've been extremely pleased with the Write Up.

I have been using Dillner's program for Write Up & Payroll since 2004 and whenever I have any issues the team over there always takes care of me. They respond quickly to my issues and are always pleasant to speak to on the phone.

We use it for both Write Up and Payroll. You can't beat their support ANYWHERE! I'm biased, since I've used their system from the get-go, and have been on Dillner's Advisory Board so I've been involved in the development of the system. But, in my humble opinion, you won't find a better write-up system anywhere for whatever cost. And when you throw in the cost, well, there is no comparison. As far as payroll goes, it is not a service bureau system. But if you just want to do payroll for your write-up clients, it is very serviceable.

We have been using Dillner's since 2006 and we are so glad we made the change. The first few months were rough with the conversion but the training and especially the support have been OUTSTANDING. The entire crew is extremely patient when we get ourselves in trouble and there is a problem we created with a particular file. We are not using the program to its full extent and that is one of our goals this year. We are especially looking forward to this year's Users Conference.

What a slick and fantastic transfer program. I transferred all of my accounts over from Advantage to FCA in one month and had not a single problem. I seem to be able to go back and print any report I need - it is all there. It made the transition from Advantage to FCA so much easier! I would not hesitate to recommend FCA at all!
