Disclosure: ClientBrief is a competing product. This review is based on each vendor's published pricing and documentation, and on themes that recur consistently across public review platforms — not on extended hands-on use of the product. We publish no star rating because we have no basis for one. Where a tool is better than ClientBrief for a job, this page says so.
Double — the month-end close automation tool that was called Keeper until it rebranded in October 2025 — is a narrow, well-reviewed product built around one job: reading a connected QuickBooks Online or Xero ledger, flagging miscoded transactions and missing information, and giving a bookkeeping team a structured queue to work through before close instead of hunting the general ledger line by line. Reviewers on G2 and Capterra consistently credit it for exactly that, especially its Accruals handling and a client portal that consolidates document requests and Q&A that would otherwise scatter across email. Its pricing is the detail that changes the calculus: Double charges $10 to $50 per connected client per month across its Core, Plus, and Scale tiers, with unlimited staff seats included on every one — the inverse of nearly every other tool reviewed on this site, which charge per user and give away clients for free. That makes Double cheap for a lean, growing team serving a handful of substantial clients, and expensive for a practice carrying a long tail of small monthly clients, since every client added raises the bill directly. It also isn't a full practice management suite — no invoicing inside the CRM, no e-signature or engagement letters, and tax-specific work costs an extra $200/month on an annual commitment — so firms that want one platform for the entire client relationship will likely still run a second tool alongside it.
Double is AI-assisted month-end close software for bookkeeping and accounting firms — and separately for internal finance teams — built around a two-way sync with a connected QuickBooks Online or Xero ledger (a separate plan for internal finance teams adds NetSuite and Sage Intacct). Its core mechanic is automated file review: the system scans the connected ledger and surfaces miscoded expenses, transactions missing a payee or a class/location/customer field, uncategorized entries, and vendor-level P&L anomalies, so a bookkeeper works a flagged queue instead of reviewing the general ledger line by line. Around that sit a custom-branded client portal — clients log in through a passwordless Google magic link rather than a username and password — task management, receipt handling, accruals and allocations, AI-drafted journal entries, and an AI assistant called 'Ask Double' for financial-summary and flux-analysis questions. The company operated as Keeper from its 2020 founding until the October 2025 rebrand, and it says the platform is now used by more than 4,000 accounting and bookkeeping firms across North America.
Pricing at a glance
Double prices per connected client per month rather than per user, across three mix-and-match tiers confirmed on its live pricing page: Core at $10, Plus at $25, and Scale at $50 per connected client, every one including unlimited staff seats. A quote-only Enterprise tier extends the same accounting-firm product for larger practices, and a separate plan serves internal finance teams. The Tax Suite add-on requires a $200/month annual commitment on top of per-client fees, and connecting an additional team email costs about $10/month (one practice email is included free on Core). You need at least one connected client to start a subscription, and Double doesn't offer self-serve signup — every plan runs through a personalized sales demo first.
Double scans the connected QuickBooks Online or Xero ledger for miscoded expenses, transactions missing a payee or class/location/customer field, uncategorized entries, and vendor-level P&L anomalies, then hands the bookkeeper a flagged queue instead of a blank general ledger to comb through. G2 reviewers specifically call out the Accruals feature as unusually accurate for prepaid expenses and deferred revenue — a detail precise enough that it reads as genuine product feedback rather than marketing copy.
A recurring theme in reviews is that keeping client questions, uploaded documents, and bookkeeping items together cuts down the email back-and-forth that normally accompanies month-end close. The client portal also uses a passwordless Google magic-link login rather than a traditional username and password, which removes one of the more common reasons clients avoid opening a portal at all.
Every plan — Core, Plus, and Scale — includes unlimited staff seats, so hiring a fifth or fifteenth team member doesn't change the bill at all. For a growing firm serving a small number of substantial clients, that inverts the usual per-seat math in the buyer's favor.
Beyond the core file-review scan, Double includes AI-drafted journal entries, an 'AI Fix this Rec' tool for reconciliation issues, AI flux analysis, and an 'Ask Double' assistant for financial-summary questions — all included on every tier rather than gated as a separate add-on.
Both Capterra and G2 reviewers single out responsive support — one Capterra reviewer specifically credited the team for listening to and shipping feature requests. That matters more than usual here, since several of the documented gaps below, like recurring-task setup and template depth, are the kind of thing a responsive product team can close over time.
Because Double bills per connected client rather than per user, growing your client list raises the bill directly, where a per-seat competitor would absorb new clients for free. Run against Client Hub as a concrete example: a three-person firm with 10 clients pays roughly $100-350/month on Double versus about $177/month flat on Client Hub's Practice Manager plan, but the same firm with 50 clients pays $500-2,500/month on Double while Client Hub stays at $177. Count your actual client list before trusting that the per-client rate looks cheap.
Double's published feature list covers file review, task management, reporting, and the client portal, but not billing. A Capterra reviewer names this specifically as a drawback for firms that want billing centralized alongside client communication rather than handled in a separate tool.
G2 reviewers using the Xero side of the integration describe having to log back into Xero and Hubdoc periodically to refresh the connection, with documents not always syncing seamlessly between the platforms. QuickBooks Online reviewers don't report the same friction, so this appears specific to the Xero path.
There's no e-signature, engagement-letter, or proposal functionality anywhere in Double's published feature list, and tax-specific work requires the Tax Suite add-on at a $200/month annual commitment on top of per-client fees. Firms wanting TaxDome- or Karbon-style breadth will be running a second platform regardless of which Double tier they buy.
Capterra reviewers describe the template library as limited next to competing tools, and note that setting up recurring client requests and tasks — the bread-and-butter of monthly bookkeeping engagements — is less straightforward than in some rival products.
Double is a genuinely strong product at the one job it was built for — reading a connected ledger and surfacing what a bookkeeper would otherwise have to find by hand — and reviewers on G2 and Capterra back that up consistently rather than describing a tool that only looks good in its own marketing. The catch is entirely commercial: per-client pricing is a real advantage for a lean, growing team serving a handful of substantial clients, and a real liability for a practice built on volume, since every additional client raises the bill directly rather than being absorbed the way it would under per-seat pricing. Model your actual client count against the $10-50 per-client range before taking the 'unlimited users' pitch at face value, and plan on a second tool if you need invoicing, e-signature, or broader workflow features that sit outside what Double actually does.
Where ClientBrief fits: we don't compete with Double (formerly Keeper) across its whole feature set and won't pretend to. ClientBrief does document collection only — send a checklist, clients upload with no account, reminders go out automatically — for a flat $7.99/month with unlimited clients. If that's the specific job you're trying to solve, it costs a fraction of a platform. If you need the rest of what Double (formerly Keeper) does, you need Double (formerly Keeper).
Is Keeper the same company as Double?
Yes. Keeper rebranded to Double in October 2025, and the old keeper.app address now redirects to doublehq.com — same product, same team, new name. It has no connection to Keeper Security, the password manager, which is a separate company that still operates under the Keeper name, so don't let that similarity confuse a vendor comparison.
How much does Double cost?
Double bills per connected client per month rather than per user: Core at $10, Plus at $25, and Scale at $50 per connected client, confirmed on its live pricing page, with unlimited staff seats on every tier. A quote-only Enterprise tier covers larger practices. The Tax Suite add-on requires a $200/month annual commitment, and each additional connected team email costs about $10/month.
Does Double charge per user?
No, and that's the detail to understand before comparing it to anything else in this category. Every plan includes unlimited staff seats — the bill scales with how many client ledgers you connect, not how many people work on your team. Nearly every other practice management tool reviewed on this site charges the opposite way.
Is Double cheaper than Client Hub?
It depends entirely on your ratio of clients to staff, and the ranking genuinely flips with firm shape. A three-person firm with 10 clients pays roughly $100-350/month on Double against about $177/month on Client Hub's Practice Manager plan; the same firm with 50 clients pays $500-2,500/month on Double while Client Hub stays flat at $177. See our full Client Hub vs Double comparison before assuming either headline rate applies to you.
Is Double the same kind of tool as TaxDome or Karbon?
No. TaxDome and Karbon are broad practice management suites covering proposals, e-signature, engagement letters, billing, and workflow automation. Double is narrower by design: it reads a connected ledger and flags errors before close, with no e-signature or proposal functionality of its own. Some firms run Double alongside a broader platform rather than choosing between them.
Does Double include invoicing?
Not inside the platform itself. Double's feature list covers file review, task management, reporting, and the client portal, but billing isn't one of them — a Capterra reviewer flags this specifically as a drawback for firms that want billing centralized alongside client communication.
What are the main complaints about Double in reviews?
The recurring themes on G2 and Capterra: no invoicing inside the CRM, a template library reviewers describe as limited next to competitors, recurring monthly-client task setup that's less straightforward than in some rival tools, and a Xero integration that reviewers say sometimes needs re-authenticating to keep syncing cleanly. None of these contradict the file-review feature itself, which is what reviewers consistently praise.
Does Double have a free trial?
Not a self-serve one. Double sells through a personalized demo, and you need at least one connected client to start a subscription — the company suggests connecting your QuickBooks Online Accountant account if you don't have a client ready to link.
What ledgers does Double work with?
QuickBooks Online and Xero for the accounting-firm product. A separate plan for internal finance teams adds two-way sync with NetSuite and Sage Intacct. If your clients sit on a different ledger, the automated file review has nothing to scan.
Is Double worth it?
For a firm with a small number of substantial clients and a growing team, yes — unlimited users combined with reviewer-verified error-catching on the ledger is a genuinely useful combination. For a practice carrying many small monthly clients, the per-client fee adds up fast, and Double still won't replace the billing, e-signature, or broader workflow tools many of those firms also need.
