Tutorialku.com is a site that serves the sale of various software for business purposes on-line. Previously it had operated off-line, under the company name TRIGONAL SOFTWARE. The products sold on this site were initially dominated by products from Bamboomedia and Inspiration Media Kreatif. Gradually we will try to complement our products from other manufacturers, not limited to business software but also various types of hardware and other supporting devices. We guarantee that the products we sell are original products. And we try our best to serve our customers the best we can.
