About ProfitLine
ProfitLine provides bookkeeping, accounting, and back-office services to small businesses and nonprofit organizations across the United States, working through best-in-class cloud applications.

Dianna O’Doherty
Chief Executive Officer
Leadership
Managers make better decisions when their organization's books are in order and its financial processes are robust. Everything ProfitLine does starts there.
Dianna leads ProfitLine as CEO, and the standard she sets is visible in how engagements run: accurate records maintained on a schedule, responsive communication when a question can’t wait, and reporting that answers a real operating question rather than restating the general ledger.
Clients describe the team as knowledgeable well beyond accounting, responsive, and genuinely invested — several have worked with ProfitLine for close to a decade. That longevity is the outcome the firm optimizes for.
The team spans accounting managers, client accountants, accounting assistants, and office operations, so no client depends on a single person to keep their books moving.
How we work
We clean up historical records, reconcile every account, organize the supporting schedules, improve the chart of accounts, and connect your cloud-based systems so the data has somewhere reliable to live.
Your day-to-day finance function runs on our side: bookkeeping, invoicing, receivables, payables, reimbursements, reporting, HR support, and the recurring compliance workflows that otherwise slip.
Timely reports land on a schedule you can plan around — with project or program visibility, cash-flow clarity, and the context leadership needs to act rather than interpret.
The team
Every client is supported by a named accounting manager and a client accountant, with office operations keeping the schedule on track.
