Clinked positions itself as a next generation client portal, but it's really a document management and collaboration platform, since there are no client management tools of any kind (no CRM, quotes, billing, or time tracking and employee workload management tools). Clinked document management module is quite good and ability to brand mobile app is something that very few vendors offer. Among Clinked negatives, other than shortage of client management and collaboration tools, is a lack of free plan or a self-hosted edition that can be put on your server. If you are looking for a free Clinked alternative that gives you 35+ client management tools, and be can used both in cloud and on-premise, Bitrix24 is worth taking a spin.
