You can immediately use TimeTraces after purchasing your license. Furthermore, all versions released within one year after purchase can always be used free of charge, and you get free technical support via e-mail when necessary.
If you want to use a newer TimeTraces version released after this first year, then your license can be updated at a reduced price.
And if you are not satisfied afterwards, you can always ask for a refund within 30 days after purchase!
The payment processing is handled by Avangate, a leading e-commerce provider.
