When you buy Abacus SE we do not send you the program files on a floppy disk or CD. Instead, you obtain the program by downloading it from here on our web site and installing it on your computer. Since the file size is only 377 KB, downloading takes at most a few minutes. Then when you buy it, we will send you a special "unlock code" that you enter into your trial version of the Abacus, thus converting it to the full, registered version of the program.

We stongly suggest that you take advantage of our offer to download and try the Abacus free before purchasing, as we do not make refunds!

We currently accept payment through established credit card and payment processing companies PayPal, NorthStar Solutions and RegSoft. After they confirm your purchase, we will email you the registration code you need to unlock The Abacus and let you use all of the program's features without those nagging registration notices. The cost is only $38.

To order online from NorthStar Solutions, click here and order Product # 7175 ("Abacus - Standalone Version for Windows"). NorthStar Solutions can only accept online credit card orders at their web site.

To order online from RegSoft.net, click here and order Product #50461 ("Abacus 4.0"). RegSoft.net can also accept orders via FAX, telephone, or US mail.
