Bookkeeping is your foundation. Advisory is where you grow.
ModlOS gives bookkeeping firms the reporting, analysis, and client engagement layer to start delivering CFO-level work — and charging for it.
The books are clean. The question is what comes next.
The work is steady. Reconciliations, categorization, AR and AP, payroll tie-out. End of month you close the books, generate the P&L from QBO or Xero, send the client a PDF and a short email, and move on to the next file. You're good at this — that isn't the problem.
The problem is what you keep hearing. Clients ask “how am I doing?”and the honest answer is “your books are clean” — true, but not what they were asking. They want cash runway, gross margin trend, a budget-vs-actual that means something. You could build it in a spreadsheet; you've tried. It takes hours per client and doesn't scale.
And there's a ceiling. At your bookkeeping rate, you can only take on so many clients before you're capped on revenue. The advisory work clients are asking for is the upgrade path — you've seen other firms make the jump — but you don't yet have the tooling that would let you deliver it at a price point that makes sense.
The bookkeeping doesn't change. What you can deliver on top of it does.
Monthly close stays the same — same workflow, same accounting system. What changes is what sits on top of it: a polished, branded monthly report and a client-facing dashboard, both populated automatically from the books you already closed. The deliverable upgrades; the prep work doesn't.
Client communication moves from email to a portal your clients can log into anytime. When they ask “how am I doing?” you point to a dashboard with cash runway, gross margin, and trends already there. The answer takes seconds, not days.
And the advisory upgrade becomes real. Modeling, scenario planning, KPI tracking, and a structured engagement cadence are in the same platform as the bookkeeping you're already doing. Per-client revenue can grow significantly when bookkeeping becomes the foundation for an advisory engagement, not the whole offering.

A small fraction of one client's revenue.
Most bookkeeping firms start on Starter ($149/mo): fits a book of up to a few clients, and lets you deliver the monthly report and dashboard for each. When you're ready to add white-labeled branding and grow into double-digit clients, Growth ($399/mo) is the next step.
Pricing is per firm, not per seat — your whole team, plus every client user, included. At bookkeeping rates of a few hundred to a thousand dollars per client per month, the platform is a small fraction of one client's revenue.
