Where Comerica fits
For existing Comerica customers, the immediate decision is less about choosing among legacy Comerica tiers and more about understanding how those accounts map into Fifth Third after the transition. For historical comparison, Comerica's Basic Business Checking remains notable for having no monthly maintenance fee and no balance requirement.
Checking structure
Comerica still publishes a familiar small-business checking lineup, but this review has an unusual 2026 caveat: Comerica is actively transitioning customer accounts into Fifth Third. That makes migration timing and replacement-product terms just as important as Comerica's legacy fee schedule.
Transactions and cash deposits
Comerica Basic Business Checking includes 75 transactions per month without an activity fee and up to $2,500 of monthly cash deposits without a cash-deposited fee. Small Business Checking and Small Business Interest Checking increase the included transaction count to 300 and the cash allowance to $5,000. Commercial Checking is designed for heavier activity and uses activity pricing and earnings-credit economics.
Relationship economics
Legacy Comerica Basic Business Checking has no monthly maintenance fee. Small Business Checking has historically used a $7,500 balance threshold to waive its monthly fee, while Small Business Interest Checking uses a $15,000 threshold. Because Comerica accounts are moving to Fifth Third, businesses should confirm the post-conversion product, fee and transaction structure rather than relying only on legacy terms.

Useful as a transition review rather than a normal new-account recommendation: Comerica's legacy economics are clear, but the decisive facts are now the Fifth Third conversion terms.
