Western Alliance Bank Business checking matches the account to the way each company actually moves money.

Analysis Checking

For high-volume treasury operators. Earnings credit rate applies to investable collected balances and offsets itemized treasury fees on the monthly analysis statement. Best for companies with $500K+ operating balances and 500+ monthly transactions who consume wire, ACH, positive pay, and lockbox services.

Business Interest Checking

For small and growing businesses that maintain working capital in the operating account. Tiered APY on collected balances plus 250 fee-free items per cycle. $2,500 opening deposit. Monthly service charge waived at $10,000 average collected balance or $25,000 combined business deposits.

Commercial Checking

For mid-sized and large companies. Unlimited transactions, sweep account integration, zero-balance account structures, and treasury module pricing consolidated into analysis statement format. Supports multi-entity corporate structures with linked accounts under a single parent relationship.

Analysis Checking — Earnings Credit Economics

Analysis Checking turns operating balances into a treasury subsidy. The earnings credit rate applies to investable collected balances after float and reserve deductions, generating monthly earnings credit that offsets itemized treasury fees — wire transfers, ACH origination, positive pay monitoring, lockbox processing, remote deposit capture, per-item check charges, and account maintenance. If earnings credit exceeds fees in any period, the surplus carries forward up to twelve months.

The analysis statement itemizes every service, volume, unit price, and credit applied. Controllers reconcile treasury spend against operating balances monthly, identify services driving the most fee pressure, and right-size balances for optimal credit coverage. Companies running treasury services at scale typically find Analysis Checking more cost-effective than any flat-fee structure once transaction volume crosses roughly 500 monthly items.

Business Interest Checking — Balance-Driven Yield

Business Interest Checking pays tiered annual percentage yield on collected balances, rewarding companies that keep working capital in the operating account. The tier structure increases APY as balances grow — making this account efficient for businesses holding reserves between larger capital deployments. The opening deposit is $2,500, and the monthly service charge waives at $10,000 average collected balance or $25,000 combined business deposits across linked accounts.

The account includes 250 fee-free items per statement cycle, online banking, mobile check deposit, and bill pay through the Western Alliance Bank Business portal. Companies consistently exceeding 500 monthly transactions or consuming meaningful wire and positive pay volume typically benefit from graduating to Analysis Checking, where earnings credit offsets variable treasury fees more efficiently than flat-rate interest on balances. Transfers between tiers preserve account numbers and routing details.

Commercial Checking — Mid-Market and Multi-Entity

Commercial Checking supports mid-sized and large companies with unlimited transactions, sweep integration, and treasury module bundling. Multi-entity corporate structures link multiple subsidiary accounts under a single parent relationship — each subsidiary retains its own account number, statements, and signatory controls, while rolling up into consolidated reporting inside the business portal. Zero-balance account structures sweep subsidiary balances into a master concentration account nightly.

Treasury module pricing — wire transfers, ACH origination, positive pay, lockbox, remote deposit, BAI2 reporting — consolidates into analysis statement format. Commercial Checking pairs naturally with commercial lending relationships, with operating accounts often serving as the depository for term loan draws, revolving credit advances, and equipment financing proceeds. Dual authorization controls, IP whitelisting, and role-based permissions protect every workflow under OCC oversight.

Required Documentation

Corporate applicants provide articles of incorporation or LLC formation documents, EIN assignment letter from the IRS, operating agreement or corporate bylaws, beneficial ownership certification under the FinCEN customer due diligence rule, and government-issued identification for every authorized signer. Partnerships submit the partnership agreement. Sole proprietors submit a DBA filing and personal identification. The commercial banker reviews documentation before submitting the application to deposit operations — complete packages typically clear in five to seven business days. Entity resolutions authorizing account openings and naming signatories are standard for corporations and LLCs with multiple owners or a board structure.

From Opening to Full Treasury Enrollment

Once the core checking account opens, the commercial banker provisions business portal access for authorized users, enables dual authorization thresholds, and schedules treasury module activation. Wire transfer setup includes outbound beneficiary templates, cutoff confirmations, and RSA SecurID token enrollment for authorizers. Positive pay activation requires a sample issue file to calibrate the exception workflow. ACH origination setup includes NACHA file format validation and initial credit limit review. Most companies complete treasury enrollment within two to three weeks from checking account opening.

"Moving from flat-fee business checking to Analysis Checking cut our treasury costs 40 percent — earnings credit now covers most of our wire and positive pay spend each month."

Michael Tran — Controller, Regional Distribution Company

"Business Interest Checking was the right starter account while we were growing. Once we crossed 500 monthly transactions, the commercial banker walked us through graduating to Analysis — zero disruption."

Elena Vargas — CFO, E-commerce Brand Portfolio

"Commercial Checking handles our five operating subsidiaries through linked accounts with zero-balance sweeps. One portal login covers all of it — our treasurer stopped logging into three different bank systems."

Robert Ng — VP Finance, Multi-Entity Real Estate Holding
