We offer limited versions of the LokiCheckout to various partners. Such a trial only includes a couple of modules and it does not include support necessarily. However, because a trial is part of a sales program, we encourage you to get into touch with us, if you have any questions or doubts..
Whatever you want to change, do understand that we are very eager to make sure that the core of Loki Checkout is as flexible as possible. However, because we are human too, it might be that you are aiming for a specific customization that we didn't for see - ranging from specific string translations to custom fields with file uploads.
As soon as you bump into customization that seems a bit of a workaround (ugly stuff), do let us know right away so we collaborate to see how we can create the best solution instead.
The more we work together, the more flexible Loki becomes.
