Unlike ASME software which has several mature options to choose from, there are no easy answers for API software.

I have found it advisable to check against in house hand calcs or spreadsheets or another API program to review and compare differences.

The risk is the limited level of QC can permit more errors to be released. The advantage of working with smaller vendors is that they are more open to user suggestions, (due to significantly smaller user base), and errors caught can sometimes receive corrected builds within a day. When quoting over 100 designs a month a commercial program can be very useful, but you need to have sufficient familiarity with the code to determine when to question or suspect an error in the program. I have also received no email response yet from COADE tech support when requesting when Add 4 might be available in TANK, which I have demo'd, but not used. in either API-650 or API-620 for example. So programs typically take months to incorporate Add. I believe 2 of the 3 available programs have only one person doing the programming. None of the current API programs have anywhere near the sophistication of Compress. ITS checks for new builds via the internet similar to Compress, but the similarity stops there. The only commercially available program I am aware of that is currently available with Add 4 is ITSDesign from innovative tank solution (link in Jaydees post above). ETank is currently more complete and has API-620, but we have not been able to receive any return contact as to when API-650 Add 4 might be incorporated.
