Warranty trouble calls are reviewed Monday-Friday during normal business hours (9am-5pm Eastern), and investigated on a best-effort basis following review.
With software that is not written by us, we will seek a solution to the defect, but are not responsible for it, any more than we would be responsible for fixing a defect with Microsoft Windows. A benefit of Open Source is that a large, vibrant community contributes to it, and that it is free. However, there is also the fact that because it is written by volunteers, there is no one in particular to complain to when something doesn't work...bug fixes are done by volunteers as well, in their own time. Of course, the community's concern about code defects will typically be stronger, and resolution much faster, than were you to report a bug Windows bug!
Yes, there is a 30-day warranty on all our work, which begins upon our timely receipt of full payment. The warranty covers any errors or omissions on out part: anything in the project agreement that we accidentally omitted will be remedied, and anything that we developed that doesn't work as specified will be fixed.
Payment is normally due upon receipt of the invoice. On projects where the delivery period will be more than two weeks, we will set up a milestone payment system, in which payment is due promptly at the end of each project milestone.
Payment is always due before the results of that milestone, or the project as a whole, are turned over to you and made available for use.
