Payment Solutions at Western Alliance Bank — ACH, Wires, Bill Pay, Payroll

Western Alliance Bank payment solutions move corporate money through five primary channels. ACH origination handles domestic electronic payments over the NACHA network — standard two-day and same-day before 2:45 PM ET. Domestic Fedwire transfers settle same-day up to the 5:00 PM ET cutoff. International SWIFT wires reach 200+ countries. Online bill pay automates recurring vendor payments. Integrated payroll connects directly to ADP, Paychex, Gusto, Rippling, and other major providers.

Every payment routes through dual authorization controls above configurable thresholds. Positive pay integration protects against check and ACH fraud by matching every presented item against the issue file automatically updated from each outbound payment run. All payment activity flows into BAI2 reporting for ERP reconciliation. Commercial banking operations are supervised by the Office of the Comptroller of the Currency, and ACH activity follows NACHA operating rules in full.

ACH Origination and Same-Day Payments

ACH origination moves domestic electronic payments through the NACHA network with two processing speeds. Standard ACH settles on a two-day cycle and handles recurring payroll, vendor pay, supplier settlement, and intercompany transfers with no amount cap beyond bank-configured origination limits. Same-day ACH runs three daily windows with Western Alliance Bank accepting files up to the 2:45 PM ET cutoff — use cases include emergency payroll adjustments, urgent vendor payments, tax remittance, and B2B invoice settlement where a faster cycle improves working capital.

Origination accepts NACHA-formatted files uploaded through the business portal or delivered via SFTP for high-volume operators. Every batch runs through dual authorization where configured thresholds require two approvers before release. Return and reversal handling follows NACHA operating rules — NSF, account closed, authorization revoked, and other standard return codes post back to the originator within the required window. Pairs with cash management for automated sweep funding against the payment run.

Domestic Fedwire and International SWIFT Transfers

Domestic Fedwire transfers settle same-day through the Federal Reserve wire network with an outbound cutoff of 5:00 PM ET at Western Alliance Bank. Use cases include real estate closings, M&A funding, large vendor settlements, and other time-sensitive transfers where the ACH window has closed or the amount exceeds same-day ACH caps. Every wire runs through beneficiary template validation, dual authorization with RSA SecurID token for the releasing authorizer, OFAC screening, and confirmation messaging in MT103 format for downstream reconciliation.

International SWIFT wires reach 200+ countries through the correspondent banking network. Settlement runs one to two business days depending on currency and correspondent chain; certain currencies with direct bank relationships settle faster. OFAC and sanctions screening run on every transfer before release, and international wires above any amount typically require dual authorization regardless of internal thresholds. FX execution for non-USD wires references interbank rates plus spread disclosed before release. See wire transfers for full program detail. Commercial banking is supervised by the OCC.

Dual Authorization and Positive Pay Fraud Prevention

Dual authorization enforces two-party release on every payment above configured thresholds. One operator prepares the wire, ACH batch, or bill pay entry; a second authorized signer reviews and approves before funds release. Thresholds configure per payment type, user role, and account — typical settings require dual authorization on wires above $25,000, ACH batches above $100,000, and all international SWIFT transfers regardless of amount. Every operator action posts to the audit log with timestamp, IP address, and device identifier for compliance review.

Positive pay closes the fraud gap on the inbound side. Check positive pay matches every presented item's MICR line (account number, serial number, amount) against an issue file automatically updated from each outbound check run. Mismatches flag as exceptions for treasury review before posting — the exception window closes at 10:00 AM ET. ACH positive pay applies rules-based filters: allow list by originator ID and SEC code, block unknown counterparties, match amounts against expected ranges. Unauthorized ACH debits route to return before settlement. Both services plug directly into treasury services for full payment-lifecycle protection.

ACH processing operates under NACHA operating rules. Wire transfers route through Federal Reserve infrastructure per Federal Reserve wire services. Commercial banking supervised by OCC. Deposit accounts FDIC insured.

ACH Origination and Wire Activation

ACH origination activates first — treasury confirms NACHA file format, origination limits calibrate against expected monthly volume, and dual authorization thresholds configure against counterparty risk tolerance. Same-day ACH enablement follows after the standard ACH process runs cleanly through two or three payroll cycles. Wire transfer authority activates with beneficiary template loading for known counterparties, RSA SecurID token distribution to authorizing signers, and a shadow period confirming cutoff alignment with internal cash release schedules. International SWIFT activation includes OFAC compliance briefing and FX execution workflow review with the treasury management team.

Dual Auth, Positive Pay, and BAI2 Reporting

Dual authorization thresholds tune against payment volume patterns — too low creates operational friction on routine payments, too high exposes material wire risk. The default configuration requires dual authorization on wires above $25,000, ACH batches above $100,000, and all international SWIFT regardless of amount. Positive pay activation requires a sample check issue file for MICR calibration, plus ACH filter rule setup by originator ID and SEC code. BAI2 reporting enables from day one and captures every payment by BAI type code for ERP reconciliation. See cash management for integration with SAP, Oracle, NetSuite, Workday, and Kyriba.

"Moving vendor settlement from checks to same-day ACH cut our weekly AP run from two days of printing and mailing to a four-hour NACHA upload. Positive pay caught two forged checks in the first ninety days."

Samuel Ochieng — Controller, Regional Services Company

"The 5:00 PM wire cutoff saved a real estate closing when the counterparty sent funding instructions at 4:40. We released with thirty minutes to spare — the prior bank cut at 3:30 and we would have missed closing."

Patricia Hoang — VP Finance, Commercial Real Estate Investor

"Integrated payroll with Rippling plus dual auth on every wire above $25K simplified our controls conversation with the auditors. Every payment has two approvers on record with IP and device data."

Devin O'Sullivan — CFO, Technology Services Company
