Yes ServiceHub is free to use as part of the early access program. We might introduce paid plans with more features in the future. But when we do, there will be a free version that you'll be able to use.
ServiceHub does not currently integrate with any DMS, but they are coming! But for now, you can batch import multiple work orders to ServiceHub from a single CSV file.
ServiceHub does not require any special server installation as it is deployed on the cloud. This means that you can start using ServiceHub in minutes! Please dont hesitate to get in touch if you have any specific questions.
If you would like to provide any general feedback or to report any bugs you come across when using ServiceHub, please email us at firstname.lastname@example.org. We'd love to hear from you.
