Karbon and Jetpack Workflow both sell workflow software to accounting firms and both bill per user, so they land on the same shortlists. The difference is scope. Jetpack Workflow does one thing — recurring work, deadlines, checklists and templates — and charges $40 per user per month for it. Karbon wraps a comparable workflow engine in a shared email inbox, a client portal and billing, and charges $59-89. The decision comes down to whether you need what the extra $19-49 per user buys.

Jetpack Workflow is the better buy when the problem is purely work tracking: recurring jobs, due dates, who's doing what. It's cheaper at every tier — $480 versus $708 per user per year at entry — and simpler to set up. Karbon is the better buy when the problem is email and client communication, not just task lists: Triage turns client email into assigned work, and the Team plan includes a client portal and billing that Jetpack doesn't offer at any price. A firm that would otherwise bolt a portal and a billing tool onto Jetpack should price that whole stack against Karbon before deciding.

Pricing verified October 2026. Both vendors bill per user with an annual discount, but structure it differently: Jetpack takes a flat $9/user/month off both tiers, while Karbon's discount is $20 on Team and $10 on Business — and Karbon only offers monthly billing to teams of four or more. Add-ons are small on both sides: Karbon sells eSignature credits (from $100 for 100), Jetpack sells extra document storage ($5 per 100GB/month) and a $1,500 one-time onboarding package. The tiers also split on different lines — Karbon's step up buys automation and client reminders, Jetpack's buys time tracking and profitability reporting — so compare the tier you'd actually need, not the entry rates.
Choose Karbon if your team works out of email and things get lost between inboxes. Triage, the client portal and billing in one product can replace two or three tools you'd otherwise stack on top of Jetpack — which narrows the price gap more than the headline rates suggest. Plan on Business at $89/user/month annual if you want the system to chase clients automatically.
Choose Jetpack Workflow if you need recurring jobs and deadlines tracked reliably and nothing more. At $40/user/month annual it's the cheapest credible workflow tool in this category, there's a free trial that needs no credit card, and Premium's time tracking and Budget vs Actual reports cover firms that want job-level profitability.
If your deadlines are under control and what actually stalls work is waiting on clients for documents, neither tool fixes it — Jetpack has no client side at all, and Karbon's portal asks clients to log in. ClientBrief sends one checklist, clients upload without an account, and reminders go out automatically, for $7.99/month flat with unlimited clients.
Where ClientBrief fits in: ClientBrief is a client document collection tool — $7.99/month flat, no per-user pricing, no seat minimums, unlimited clients. Send a checklist, clients upload without creating an account, reminders go out automatically. It's narrower than Karbon and Jetpack Workflow — it skips the wider practice-management and e-signature features either one offers — so firms often run it alongside whichever of the two they pick, just for the document-chasing part.
Is Jetpack Workflow cheaper than Karbon?
Yes, at every tier. On annual billing Jetpack Starter is $480 per user per year against $708 for Karbon Team, and Jetpack Premium is $600 against $1,068 for Karbon Business. For a five-person firm that's $2,400 a year on Jetpack Starter versus $3,540 on Karbon Team. The gap reflects scope: Karbon includes a shared inbox, client portal and billing.
Does Jetpack Workflow have a client portal?
No. Jetpack Workflow is internal workflow and task management — it tracks what your team owes clients, not what clients owe you. Karbon's Team plan includes a client portal. Firms on Jetpack typically pair it with a separate portal or document collection tool.
Does Jetpack Workflow have anything like Karbon's Triage?
No. Triage, Karbon's shared email inbox where client email becomes assignable, trackable work, has no equivalent in Jetpack Workflow. If email coordination is your main pain point, that alone usually decides this comparison in Karbon's favor.
Which is better for a one- or two-person firm?
Usually Jetpack Workflow. Karbon's main advantage, Triage, is about coordinating work between people, which matters less in a very small team. A solo practitioner pays $480 a year on Jetpack Starter versus $708 on Karbon Team, and Karbon only offers monthly billing to teams of four or more, so a small firm commits to a year. If you'd use Karbon's client portal and billing, factor in what you'd otherwise pay for those.
Can I switch from Jetpack Workflow to Karbon?
Client and contact lists can generally be moved over by spreadsheet import, but job templates and recurring schedules don't transfer — you rebuild them in Karbon. Firms that switch typically budget several days for template reconstruction and avoid doing it during filing season.
