Custom Software, Inc.

What we do

Retail I.T., end to end.

From the register up front to the back-office reports — and every wire, scanner, and printer in between — Custom Software builds and supports the systems your store runs on.

Retail Point-of-Sale

Our in-house POS is purpose-built for small retailers and convenience locations. Fast at the register, intelligent in the back office, and tightly integrated with the Retail Management System below.
