Mentor law firms, engineering shops, marketing agencies, and Northeast Ohio consultants run on billable hours, retainers, and project P&L. We build a clean bookkeeping system around how you actually bill — and handle Ohio's municipal withholding for hybrid teams — so partners see real margin, not just invoiced revenue.

Mentor's professional-services bench runs deep — and the books behind these firms look nothing like a retail P&L. Here's how Tides fits the partners, principals, and owners building practices across Lake County.
The Northeast Ohio pro-services density is substantial. Engineering and consulting firms here support the corporate and manufacturing corridors anchored by STERIS, Avery Dennison, Great Lakes Mall retailers, and area manufacturers. Alongside them, law firms handle corporate matters, IP work, and a flood of real estate and construction law driven by the building boom.
the Great Lakes Mall district and the surrounding corridors are home to a dense mix of marketing, branding, PR, and creative agencies serving regional and national clients, with architects and design studios filling out the picture. For all of them, payroll and owner draws run headfirst into Ohio's municipal income tax: Mentor and the Lake County communities file municipal income tax through RITA, so any business with staff working across city lines is withholding and filing local income tax in several jurisdictions. And once a growing firm crosses Ohio's $3 million Commercial Activity Tax (CAT) gross-receipts threshold, that becomes one more filing to stay ahead of.
The bookkeeping reality is the same across the board: revenue ties to billable hours, retainers, or project milestones — not invoice dates. We integrate with Clio, Harvest, Toggl, and similar time systems, build a chart of accounts that throws off real project and client P&L, handle IOLTA reconciliation for law firms, keep multi-city municipal withholding straight, and clean up partner distributions, equity draws, and billable utilization so principals know exactly what each engagement earns.
