Treasury services at Comerica: middle-market reference

The Comerica treasury services product line

Six product families cover the practical treasury workflows of a middle-market business: cash management, payments origination, lockbox, positive pay, sweep accounts, and fraud-prevention services.

Cash management at Comerica covers daily reporting, multi-account visibility, and the consolidated dashboard that a finance team uses to monitor liquidity across operating, payroll, and reserve accounts. ACH and wire origination is the payments-out workflow, with delegation tools that allow controllers to grant initiation rights to specific staff while keeping approval authority at a higher level.

Lockbox is the receivables-side counterpart, where customer payments mailed to a Comerica-managed PO box are processed, scanned, and posted to the accounting system without the business having to handle paper. Positive pay is a fraud-prevention service that checks each presented cheque against an issued-cheque file and flags discrepancies before payment.

Sweeps, working-capital lines, and the broader relationship

Sweep accounts move excess balances overnight into yield-bearing instruments and back into operating accounts each morning, optimizing the cash-yield curve without manual intervention.

Sweeps are the unsung hero of corporate treasury operations. The mechanic is simple: end-of-day excess balances above a target threshold sweep into an overnight yield instrument; balances below the threshold pull from a working-capital line of credit to top up. The treasury team sets the parameters once and the system handles the daily execution. Comerica’s sweep capability has been a recurring strength in the relationship-banking pitch to middle-market finance teams.

Pricing and the relationship-banking model

Treasury services pricing at Comerica is relationship-driven rather than off-the-shelf, which means the actual cost depends on the broader business-banking relationship.

For a middle-market business evaluating treasury providers, Comerica’s pricing is typically negotiated as a package that includes deposit-account fees, transaction volumes, and the offsetting earnings credit on operating balances. A finance team that walks in with realistic deposit volumes and transaction counts gets a more accurate quote than one that asks for a published price list. Public-research orientation guidance from the CFPB covers consumer-finance fundamentals; for commercial-treasury fundamentals, the AFP (Association for Financial Professionals) publishes useful comparison frameworks.

Fraud-prevention services in the treasury layer

Treasury fraud has been one of the fastest-growing risks in middle-market corporate finance over the last five years, and the prevention-service layer Comerica offers reflects that trend.

Cheque fraud is still the most common attack vector despite the steady migration to electronic payments. Positive pay, payee-positive pay, and reverse-positive pay variants each address slightly different attack patterns. ACH-debit fraud has grown alongside digital payments; ACH positive pay is the parallel control. Wire-fraud prevention typically combines callback verification, dual approval, and out-of-band confirmation for any new beneficiary. The treasury team setting up the prevention layer should think through the realistic threat model before picking the products.
