Since we are a SaaS provider, we don't per se have software that can be re-sold. The end-user uses LeanKit on our servers. When a customer needs additional licenses, the account owner can add those instantly through the Account Details page.
However, we do recognize the valuable license administration services that software re-sellers like Insight Global or SII provide to their clients. So, we are happy to include them on invoices (alongside the end purchaser) so that they have the information they need to properly do their job.
