01, What we do
Each engagement is led by a senior advisor who understands your situation and stays with it year-round.
Accurate, on-time returns for individuals and businesses, so you keep more of what you earn and never miss a deadline.
Proactive, year-round planning that lowers your liability before the year closes, while there is still time to act.
Clean books and reliable payroll, so you always know where you stand and your team gets paid right.
If the IRS comes calling, we stand in front of you, with experienced representation from first letter to final resolution.
Clear-eyed advice on cash flow, structure, and growth: a CFO's perspective without the full-time cost.
Experience with the numbers that matter to physicians, real estate, retail, and privately held companies.
Cross-border tax for U.S. companies operating abroad, foreign corporations here, and individuals on either side of the border.
Plans that protect your family and keep ownership transitions smooth, with tax exposure minimized for your beneficiaries.
02, Leadership
OMNEX pairs hands-on management today with the legacy it was built on, senior-level attention and proactive planning, held to the same standard since 1987.
Ahmad founded OMNEX in Dearborn in 1987 and grew it into one of the largest tax and accounting firms in the region, serving hundreds of business and individual clients. In 1992 he co-founded the American Arab Chamber of Commerce, which he chairs and which today represents more than 1,300 member companies.
Belal leads OMNEX day to day, holding the firm to the standard it was built on: senior-level attention, proactive planning, and continuity year over year. Clients work directly with a principal who knows their file, not a rotating desk.
03, How we work
The same disciplined process behind every client: documented, advisor-led, and built to run year-round rather than scramble each April.
A structured intake of your books, prior returns, and goals, so we start from a complete, documented picture rather than guesswork.
A proactive tax and entity strategy mapped to your year, with decisions made in time to act on them and reviewed with a senior advisor.
Filing, bookkeeping, and payroll handled on a clear cadence, with a second set of eyes on every engagement and a secure portal throughout.
Scheduled check-ins in June and November, not just April, so questions get answered before they become problems.
04, Industries
Different businesses face different numbers. We've spent decades getting fluent in the ones that matter most across Metro Detroit.
Practice structure, payroll, and tax strategy built for how clinics really run.
Depreciation, 1031s, and entity planning that keep more of every deal.
Inventory, sales tax, and cash flow handled so the floor stays your focus.
Board-ready reporting and advisory for owner-led companies that are scaling.
One partner for books, payroll, and tax, so you can run the business.
