Your clients' books, in your custody.

An accounting practice holds a complete financial portrait of every client: payroll, bank statements, tax filings, ownership structures. Much of it is personal data under GDPR and KVKK; all of it is confidential by the standards of your profession. Clients rarely ask where it's stored — they assume the answer is 'with you'.

Then there's the calendar. Closing periods and tax season compress a year of coordination into a few weeks — and when that coordination runs on email threads and consumer messengers, deadlines live in inboxes, client documents drift into the wrong chats, and separation between clients is whatever people remember to maintain.

Polybase gives the practice one workspace it runs itself. Each client engagement gets its own channel — documents, tasks and discussion in one place, membership explicit. Deadlines become tasks with due dates, statuses and List, Board and Timeline views. And self-hosted, everything stays on your infrastructure, with portable backups you can hold in your hand.
