Birchwood is a small CPA firm for Michigan small businesses and the families who run them. Straight answers, tidy books, and a partner who picks up the phone.
No phone trees, no junior handoffs, no surprise invoices. You work with the same two partners all year, and tax season is a continuation of a conversation, not an ambush in April.
We publish our starting prices, return calls the same day, and explain every number in plain English. Owners tell us that alone is worth the fee.
“Our old firm sent invoices. Birchwood sends explanations. I understand my own company better after two years with them than after ten with the previous guys.”
“Marta found an election our previous preparer missed three years running. It paid for the engagement several times over, and she explained it so I actually understood it.”
“The monthly one-pager is the only financial document I read start to finish. My banker asked who does our books. That felt good.”
