Double vs SOGo
A side-by-side editorial comparison of Double and SOGo — release velocity, themes, recent moves, and the top alternatives to consider.
Double vs SOGo: at a glance
What is Double?
Ask Double can now read and post in Microsoft Teams on an accountant's behalf.
Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 22 release connects Ask Double to Microsoft Teams, where it can read chats and channels and send messages as the user after confirmation, and lets it draft executive summaries and act on batches of tasks. Bookkeeping work continues alongside: customer-level and whole-P&L allocations, partial fixed-asset disposals and reminders for every open client request. The week before brought Ask Double to Xero and Consolidations in beta.
What is SOGo?
SOGo's release notes have become a vulnerability disclosure channel with a version number attached.
SOGo is a self-hosted groupware suite — webmail, calendaring and contacts — maintained by Alinto. Four of the last six releases exist primarily to fix security vulnerabilities: XSS through malicious mail, SQL injection, OpenID impersonation, script execution via theme and hint query parameters. The newest, 5.12.10, fixes four more and states that all previous versions are affected, with CVE identifiers still pending at publication.

◆ Current state
Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 22 release connects Ask Double to Microsoft Teams, where it can read chats and channels and send messages as the user after confirmation, and lets it draft executive summaries and act on batches of tasks. Bookkeeping work continues alongside: customer-level and whole-P&L allocations, partial fixed-asset disposals and reminders for every open client request. The week before brought Ask Double to Xero and Consolidations in beta.
◆ Where it's heading
Two tracks run in parallel: fuller QBO bookkeeping coverage and an AI layer that reaches across a firm's tools. Teams is the first connector in these entries where Ask Double writes outside the ledger, not just reads, with a confirmation step as the guardrail. The assistant is becoming the way staff operate Double in bulk, from tasks to reports.
◆ Prediction
Expect more write-capable connectors with the same confirm-before-send pattern, and Ask Double on Xero gaining write actions after its read-only beta.
SOGo
2.5COLLAB
SOGo's release notes have become a vulnerability disclosure channel with a version number attached.
◆ Current state
SOGo is a self-hosted groupware suite — webmail, calendaring and contacts — maintained by Alinto. Four of the last six releases exist primarily to fix security vulnerabilities: XSS through malicious mail, SQL injection, OpenID impersonation, script execution via theme and hint query parameters. The newest, 5.12.10, fixes four more and states that all previous versions are affected, with CVE identifiers still pending at publication.
◆ Where it's heading
The pattern is a codebase whose input-handling surface is being systematically probed, largely by the community reporting to the project's bug address, and patched in batches. Release numbering has stopped being reliable as a timeline — 5.12.7 shipped after 5.12.8 — so version order tells you nothing about what a deployment contains. The two non-security releases in this window were both regression repairs from the security releases that preceded them, which is the cost of shipping fixes at this cadence.
◆ Prediction
Given four security batches in five months and CVE identifiers still being assigned retroactively, another batch on the same cadence is the most likely next release, with a regression patch following it.
