I have been using xtuple for a year now. I know know what I like about it and what I dont. What I like about it: - qt: the client is multiplatform (Win/Mac/Linux); dev tools are mature for roll your own extensions. - good structure for adding in custom modules (forms and reports), especially the built in qt ide. - completeness: xtuple has all of the core modules/functionality (some of which you actually have to buy, but that is how they pay thier bills). - free: postbooks edition has no user limits, so we can afford to really *use* it as an erp system... with 10 users most erp systems cost around $50K to $100K + $20K / yr in maintenance... I cant afford that. - good support: the developers do look at and respond to bug reports; even for unpaid support. What I cringe about: - qt: the client design standards have broken down; this is rev 3 of the product, over time different people have built core screens differently (ie buttons are in different places, new/save behave differently, form layouts are inconsistent). - qt: looks very bland: this is an important point; the look and feel of the screens affects usability. A screen that uses color and images *properly* is easier to work with. - openrpt: the report writer is functional, it prints canned reports well. but that is it. weakest part of the product. - not free: the manufacturing module is not free; this is the core functionality most companies need. xtuple makes you pay for it. The ultimate assessment is: given a choice, would I use xtuple again? For a FREE solution, yes. I evaluated 4 of the other "opensource" guys first and postbooks is the best of the lot. For a PAID solution: no. Once I start paying $50K for my ERP system, there are a lot more options out there.
I heard very good comments about postbook. I have downloaded the installer "xTuple-4.5.0-windows-installer". I tried to install on my 64 bit windows 7 machine, but its not installing. I am getting the following error "Error copying file from packed archive <PATH>\xTuple-4.5.0-windows-installer.exe to <PATH>\QtGui4.dll" Can anyone help me?
