I've been using ProSystem F/X and ATX long before they went under the same umbrella and found almost every year I ended up happy I had a backup package. I've not been following the "where is CCH going with ATX, blah, blah" while knowing CCH has at least now 3 competing packages. That said, CCH Canada has 2 competing Canadian tax package and they've supported both for something like a decade. Not sure why or if the market really is large enough to really economically support both within one company.
Last year drove me nuts with ATX both from a service point and software point, more so than the year before. I've stayed with them for this year based on promises but, it may need a review and I'll monitor closely as if things do not look better very early on, I'll simply convert the ATX files over to ProSystems and do away with the frustration. The PRS pricing for Prosystems and initial costs is very reasonable, more so than just a couple of year ago when you had to be a good sized form to think about the software. I charge through a fee for using either software to the client to recoup my costs so in the end the cost is usually about the amount of the ProSystem license fee and almost nothing for the MAX. Not a big difference.
I did a quick look at Drake as I've received a lot of e-mails from them and noticed you can upload a spreadsheet of shares transactions into Sched D. I have to do a lot of spreadsheet work related to this as my clients have Canadian dollar investment accounts as well as US dollar accounts and I have to convert both the purchase and proceeds using spot rates them retype everything into the US return and again into the Canadian return. I'll exlore what Drake has just because it can possibly reduce a lot of time just for this one schedule it can work.
