Not built for a client engagement
These platforms were built for a range of industries. Audit engagements need structured PBC requests with owners, deadlines, and oversight that both sides can see and act on.
Auditi vs Nextcloud
Nextcloud is a capable platform for securely storing files, but it wasn't purpose-built to run the client-facing side of an audit. Auditi brings file requests, confirmations, communication and project management into one secure workspace built specifically for audit firms and their clients.
Trusted by 500+ audit firms, including Baker Tilly, RSM and Crowe

The difference
For secure file exchange, general purpose platforms are a strong choice. Judged as the workspace where you and your audit clients collaborate, the gaps start to show. The question isn't just whether your files are secure. It's whether it can handle the full workflow of a client engagement during an audit.
These platforms were built for a range of industries. Audit engagements need structured PBC requests with owners, deadlines, and oversight that both sides can see and act on.
Audit teams need to send, track, match and document confirmation responses from banks and other third parties. A shared folder gives you somewhere to file the replies, not a way to run the process.
Building on top of a general purpose tool becomes an ongoing IT project which costs internal resources. If you self-host, your IT team becomes responsible for maintenance, admin and server security too.
The problem
Without a dedicated workflow, your options are custom development or bolting on other tools. Typically this means PBC requests go out ad hoc. Files land in a folder, questions sit in emails or file comments, and the PBC list holding it all together lives in a spreadsheet. Multiply that across every engagement and it's a season's worth of admin.
Your clients' experience becomes your firm's reputation
Status lives in a spreadsheet, files live in a folder, and answering "where are we?" means reconciling both.
Clients upload into a folder with no sense of what's been accepted, what's outstanding or what's next.
Every reconciliation, repeated request, extra email and unanswered question adds days and extra cost to the engagement.

Auditi was founded in 2012 by two auditors and two IT experts. We're trusted by reputable audit firms across the world including Grant Thornton, Moore, Baker Tilly, RSM, Crowe and more.

Questions
Auditi starts at $29 per firm user per month. Nextcloud is open source and can be self-hosted for free in some circumstances, but enterprise pricing starts at €71.29 per user per year with a 100-user minimum (checked on Nextcloud pricing on 25 August 2026).
The licence fee is rarely the whole cost. If you self-host then there may be IT costs for managing a server. Extending the platform's functionality also means paying a developer. Both are ongoing.
The largest cost is usually the least visible. It's the auditor time lost on engagements that run long because evidence was slow to arrive.
