Keeper (now Double)

Worth saying up front: the product many firms know as Keeper rebranded to Double in 2025 (keeper.app now redirects to doublehq.com). It is the AI bookkeeping-review platform — not the password manager — and it’s a favourite for catching errors before they reach the return.

What it actually is

Double (formerly Keeper) is an AI ledger-review and client-management tool for bookkeeping and client-accounting-services (CAS) firms. It flags unreconciled accounts, uncategorized and payee-less transactions and categorization inconsistencies, manages the month-end close, and gives clients a branded portal where questions attach directly to transactions.

Pricing, in plain terms

The model is per connected client, with unlimited users included. The live pricing page now gates tiers behind a demo, but historically (and still widely cited) it ran roughly $8–$10 per client per month, with a core plan referenced around $200/month and paid add-ons for email and a tax suite. Confirm current numbers on a demo.

Where it shines

The review signal is striking on G2 — 5.0 from about 75 reviews — and reviewers praise how much it compresses the monthly close, the clean two-way QuickBooks Online and Xero sync, and tagging client questions to specific transactions instead of juggling spreadsheets.

What to watch

Capterra tells a more mixed story (3.8 from a small 5-review sample), so I weight the two together. The honest limitations: it’s narrower than a full practice-management suite (no proposals, billing or capacity tracking), the integration list is essentially QBO and Xero, and per-client pricing grows with your book.

My verdict

For a CAS or bookkeeping firm that wants to systematise ledger review and the close, Double is a sharp, well-liked tool. Just know the name changed, and price it against your client count.
