Plante Moran is taking its biggest swing outside U.S. borders yet, folding a Latin American accounting firm into its network in what the company is calling the largest international expansion in its history. The Southfield-based firm is bringing local teams across Mexico and other Latin American markets into the fold, boosting its ability to handle taxes, transfer pricing, and cross-border compliance for U.S. clients. For a Michigan outfit, it is a sizable step toward deeper in-region advisory support as more clients push operations overseas.
According to Crain's Detroit Business, the deal was announced today and centers on a tie-up with Mexico-based JA Del Río. The Crain's piece, written by Anna Fifelski, describes the move as the firm's biggest international expansion and underscores Plante Moran's Southfield headquarters.
What JA Del Río Brings
JA Del Río, founded in Guadalajara, has offices in Guadalajara, Mexico City, Monterrey, León, and Tijuana, along with additional locations in Colombia and Costa Rica, according to JA Del Río. Its menu of services includes audit, tax, transfer-pricing, foreign-trade advisory, and outsourced accounting, a set of capabilities that folds neatly into Plante Moran's existing cross-border work.
How It Changes Plante Moran's Footprint
Plante Moran already cites international offices in Monterrey, Shanghai, Mumbai, and Tokyo and employs nearly 4,000 professionals. The addition of JA Del Río bolsters its coverage in Latin America and expands local-language capacity, the firm notes on its website. With that increased scale, clients can seek more coordinated advice on taxes, customs, and payroll across their U.S. and Mexican operations instead of juggling multiple advisers.
Why It Matters For Michigan Clients
For Michigan manufacturers and private companies that rely on Mexican suppliers or operate facilities there, the expanded network is pitched as a way to get closer access to advisers who understand local tax and customs rules. The partnership also reflects a wider play among U.S. advisory firms: build up on-the-ground teams where clients actually do business rather than trying to manage everything from far-flung offices.
