Double — the accounting tool that was called Keeper until October 2025 — costs roughly $10 to $50 per connected client per month, across three mix-and-match tiers, with unlimited users included at no extra charge. That per-client basis is the important part: unlike almost every competitor, Double's bill scales with how many client books you connect, not with how many staff you hire. Firms wanting the Tax Suite add-on need a $200/month annual commitment, and connected team emails are about $10 each per month.
Double prices per connected client, per month, with unlimited users on every plan. Tiers are mix-and-match, so different clients in the same account can sit on different tiers depending on what work you actually do for them — a light compliance client and a full advisory client don't have to cost the same. You need at least one connected client to subscribe. This is the inverse of how Client Hub, Financial Cents, Karbon, and TaxDome charge: those bill per staff seat and let you add unlimited clients, while Double lets you add unlimited staff and bills per client.

Double's per-client pricing is genuinely good for firms with a small number of high-value clients and a growing team, and genuinely bad for firms with a long tail of small monthly clients. Run the arithmetic against your actual client list rather than against the headline rate: a five-person firm serving 40 small bookkeeping clients will pay far more on Double than on a per-seat tool, while a two-person firm serving 8 substantial clients will pay far less. That inversion is the entire decision.
Comparing against ClientBrief: ClientBrief is $7.99/month flat — no per-user pricing, no seat minimums, no annual commitment, and unlimited clients and checklists. It covers document collection only: send a checklist, clients upload without an account, reminders go out automatically. It is not a replacement for Double (formerly Keeper)'s wider feature set, and firms often run both.
Is Keeper the same as Double?
Yes. Keeper rebranded to Double in October 2025, and keeper.app now redirects to doublehq.com. It's the same accounting product — automated file review and month-end close for firms on QuickBooks Online or Xero. Note that this is unrelated to Keeper Security, the password manager, which is a completely different company that still uses the Keeper name.
How much does Double cost?
Roughly $10 to $50 per connected client per month across three mix-and-match tiers, with unlimited users on every plan. The Tax Suite add-on requires a $200/month annual commitment, and connected team emails are about $10 each per month.
Does Double charge per user?
No — and this is the main thing that distinguishes it commercially. Users are unlimited on every tier. Double bills per connected client instead, which means hiring is free but growing your client roster isn't. Almost every competitor does the opposite.
Is Double cheaper than Client Hub or Financial Cents?
It depends entirely on your ratio of clients to staff. A three-person firm with 10 clients pays about $100-350/month on Double versus roughly $177/month on Client Hub Practice Manager or $147/month on Financial Cents Team. The same three-person firm with 60 clients pays $600-3,000/month on Double while the per-seat tools stay flat. Count your clients before comparing headline prices.
What ledgers does Double work with?
QuickBooks Online and Xero for the firm product, with the internal finance teams plan adding two-way sync with NetSuite and Sage Intacct. The automated file review depends on a connected ledger, so firms whose clients sit elsewhere get much less from it.
How much does Double cost for a firm with 20 clients?
Between roughly $200 and $1,000 per month depending on which tier each client sits on, since plans are mix-and-match per client. Staff count does not change that figure at all — a two-person firm and a ten-person firm with the same twenty clients pay the same.
Is Double cheaper than per-user practice management tools?
It depends entirely on your client-to-staff ratio, and the answer genuinely flips. A five-person firm with 10 clients pays roughly $100-500 per month on Double against $445 per month on Karbon Business — Double wins. The same five-person firm with 60 clients pays $600-3,000 per month on Double while Karbon stays at $445 — Karbon wins. Count both numbers before comparing headline rates.
Are there hidden costs with Double?
The per-client model itself is the thing to model carefully, because it inverts the usual risk: winning twenty small clients raises your software bill immediately, where a per-seat tool would absorb them for free. The Tax Suite is also gated behind a $200 per month annual commitment rather than sold per client, which creates a floor regardless of how few clients you connect.
Does Double have a free trial?
Double does not publish a self-serve free tier, and evaluation generally runs through a demo. You need at least one connected client to subscribe, so testing it meaningfully requires connecting a real ledger.
Is Double worth it?
It is worth it for firms with a small number of substantial clients and a growing team, where unlimited users genuinely changes the economics. It is poor value for a practice carrying forty small monthly clients, because that is precisely the shape the pricing model penalises. Its automated file review also solves a different problem from client-communication tools — it reads the ledger and surfaces errors rather than helping you extract answers from clients.
What is the cheapest alternative to Double?
For firms with many clients and few staff, almost any per-seat tool is cheaper — Financial Cents at $19/month solo or $49/user/month for teams is the clearest example. For document collection rather than ledger review, ClientBrief is $7.99/month flat with unlimited clients and unlimited users, so neither side of the ratio costs you anything.
