Karbon is strong practice management — triage, tasks, client requests. But the work still happens in QuickBooks, by your staff. Synoro is the layer where agents execute inside those same workflows.

The gap
Karbon is a great task and collaboration tracker, but nothing in it actually does the work — your team still drafts emails, chases documents, and builds reports in QuickBooks. Pricing is per staff seat ($89/user/month on Business, billed annually), so the bill climbs every time you hire, regardless of client count — plus payment-processing fees and eSignature credits stack on top.
Synoro's agents draft, chase, and prepare the close; Karbon-style tracking is built in, but execution happens inside governed workflows. You pay per client company ($5–$35/month), unlimited users — price grows when you win clients, not when you add headcount.

Worked example
5-person team · 50 client companies
Karbon
Karbon (5 seats)
$445/month flat — task tracking and client requests only; categorization, reconciliation, and close still land on your staff in QuickBooks.
Synoro
Synoro Plus (50 companies)
$750/month — agents run categorization, statement matching, reconciliation, and draft close with human checkpoints.
At Karbon's $445/month you get organization for ~5 people, not execution for 50 clients. Synoro's bill grows with clients — and only one of those models buys agents that do the work.
The difference
Karbon triages, assigns, and chases requests. The categorization, reconciliation, and close still happen in QuickBooks, by your staff. In Synoro, agents execute those steps inside the same workflow that tracks them. Karbon's bill goes up when you hire; Synoro's goes up when you win a client — and only one of those buys agents that do the work.
Karbon's client experience is requests and tasks. Synoro's portal publishes approved reports, live accounts, and an AI CFO — in your firm's name.
Karbon gives you time entries. Synoro computes revenue, human cost, and AI cost per client into a margin you can act on.

Per-client revenue, cost, and margin — the proof behind the claim.
Migration & coexistence
Run Synoro alongside Karbon during migration — import your client list and workflow templates, and cut over team by team. If you love Karbon's tracking, Synoro replaces the tracking and removes the doing.
