Everyone sees what they need
Roles and permissions for every action: whoever invoices does not edit users, whoever administers decides who gets in and with what rights.
Who it's for
Small businesses
In a small business everyone does a bit of everything: you need clear permissions, tidy data and no files scattered across different computers.
Contracts and deadlines under control
Customer contracts have a term, renewal and notice period; you get a summary before they expire and can have them signed online.
Attachments where you want them
Receipts and documents stay in the system or on your own cloud (Amazon S3, Google Drive, OneDrive).
