Remember the great gap in the financing software market of 2014? Rubberstamp was built in response to that. The aim was to create a bespoke solution for managing purchases within an organisation.
Enter: - a generic, customizable solution that works well for most companies.

This all happened in Dublin with co-founders James Kennedy and Richard Greenane at the reins. Now with offices in Dublin and South Africa, we are a diverse bunch of spend control freaks dedicated to your company's financial success.

“We manage a large number of video productions at any one time. Using I can instantly see what our costs were in real time rather than waiting for the bookkeepers report at the end of the following month. Because it is much simpler than alternate solutions out there, it means that my team actually use the app which in turn means the figures are accurate.”

“Having a team with users at different levels, this program is perfect! Easy to understand and use. Access and use it from anywhere makes it very effcient.

They are great and are always there to answer questions and help.”
