Cash Management at Western Alliance Bank — Sweeps, Concentration, Forecasting, ERP

Western Alliance Bank cash management is the operational engine behind corporate liquidity. Sweep configuration moves end-of-day balances into money market funds, short-term treasury, or revolving credit pay-down. Master concentration accounts consolidate subsidiary operating balances nightly, pairing with zero-balance accounts to eliminate trapped cash across multi-entity structures. Liquidity forecasts project daily, weekly, and monthly positions with assumption-driven scenarios that update in real time.

ERP integration runs through BAI2 and ISO 20022 messaging with automated SFTP delivery to SAP, Oracle, NetSuite, Workday, and Kyriba. Every module runs inside the Western Alliance Bank Business portal with multi-factor authentication, dual authorization, and full audit logging. Deposits are FDIC insured to $250,000 per depositor per ownership category under OCC commercial banking supervision.

Sweep Configuration

Target-balance rules drive end-of-day cash movement. Investment sweep to money market or treasury. Loan sweep toward revolving credit pay-down. Sub-account sweep into concentration structure.

Concentration Accounts

Master operating account receives nightly sweeps from subsidiary ZBAs. Consolidates all operating cash for investment, payment release, or loan pay-down while each entity keeps signatory controls.

Liquidity Forecasting

Daily 2-4 week transaction detail, weekly 13-week category totals, monthly 12-month rolling projections. Live assumption modeling across all three horizons simultaneously.

ERP Integration

BAI2 files via automated SFTP to SAP, Oracle, NetSuite, Workday, Kyriba. ISO 20022 CAMT.052/053 available. Direct API calls supported where ERP treasury modules accept them.

Sweep Configuration — End-of-Day Cash Movement

Sweep configuration starts with one question: what balance should the operating account carry at end of day? Once the target is set, the sweep handles the rest. Investment sweeps direct excess above the target into money market funds or overnight treasury instruments and return those funds before the next business day opens. Loan sweeps direct excess toward paying down revolving credit lines, reducing interest expense while preserving draw availability under existing facility terms. Sub-account sweeps consolidate multiple operating accounts into a master concentration structure.

Priority rules determine which sweep fires first when more than one applies — a company might pay down a revolver before investing excess, or invest first when rates favor it. The business portal records every sweep movement on the daily report and reflects the movement in the next-morning cash position. Sweep rules adjust at any time through admin-level portal access with dual authorization on material changes, reviewable under full audit log. See treasury services for integration with BAI2 reporting.

Concentration Accounts and ZBA Chains for Multi-Entity Structures

Concentration accounts solve the structural problem of multi-entity cash. A holding company with five operating LLCs cannot run treasury efficiently if each LLC keeps balances scattered across separate operating accounts — idle cash accumulates, and the parent never sees aggregate liquidity. A master concentration account at the parent receives nightly sweeps from each subsidiary's zero-balance account (ZBA). Each subsidiary retains its own operating account for payroll, vendor payments, and signatory controls, but the balance resets to zero every night.

The concentration account then becomes the single source of operating liquidity — funds pay down the revolving credit, invest into treasury instruments, or sit in a sweep-linked investment vehicle. Multi-entity companies, franchise operators, holding company structures, and multi-state businesses with separate legal entities use this pattern extensively. The Commercial Checking tier supports unlimited linked accounts under a parent relationship, making ZBA chains scale from five entities to fifty without operational friction.

Liquidity Forecasting and ERP Integration

Liquidity forecasting combines scheduled payments, expected receipts, historical seasonality, and known one-time events into three time horizons. The daily forecast covers two to four weeks ahead at transaction-level detail — each scheduled ACH batch, wire, or bill pay appears on the projection so treasurers resolve exceptions before they hit the dashboard. The weekly forecast extends to thirteen weeks at category totals suitable for rolling cash planning and covenant monitoring. The monthly rolling forecast projects twelve months for board reporting.

ERP integration runs through BAI2 file delivery via automated SFTP. Prior-day files arrive by 7 AM ET. Intraday reports deliver at 9 AM ET, 11 AM ET, and end of day by default, adjustable per client. Target ERPs include SAP, Oracle, NetSuite, Workday, and Kyriba. ISO 20022 CAMT.052 intraday and CAMT.053 end-of-day messages are available on request. The BAI code set underpinning these files aligns with Federal Reserve-published transaction classifications. NACHA operating rules govern ACH-classified entries inside the BAI stream.

All deposit accounts FDIC insured to $250,000 per depositor per ownership category. Investment sweeps outside FDIC insurance where the destination is a non-deposit product — treasury management will document insurance scope by sweep type. Commercial banking supervised by OCC.

Weeks 1-3 — Sweeps and Concentration

Sweep configuration starts with target balance definitions and destination selection — money market fund, overnight treasury repo, or revolver pay-down priority. Concentration account setup follows after every subsidiary account exists and signatory controls are confirmed. ZBA chains activate in sequence so each subsidiary's daily reset runs cleanly against the master before the next entity joins. Initial sweep and ZBA runs receive three-day shadow monitoring before cutover — treasury compares actual sweep amounts to expected movements from target balance rules. Dual authorization applies on every material configuration change across the implementation window and thereafter.

Weeks 4-6 — Forecasting and ERP Integration

Liquidity forecasting begins with a baseline import of scheduled payments and expected receipts for the next ninety days. The weekly forecast refines over three reporting cycles as variance narrows between forecast and actual. BAI2 delivery configuration includes SFTP endpoint certification, sample file exchange, and ERP import mapping into SAP, Oracle, NetSuite, Workday, or Kyriba treasury modules. Intraday schedule selection typically settles at 9 AM ET, 11 AM ET, and end of day, adjusting up or down based on internal cash cutoff timing. Companies requiring ISO 20022 messaging add CAMT.052/053 once BAI2 delivery is stable. By week six, most companies generate board-ready liquidity reports straight from the portal.

"We recovered roughly $4.2 million of idle cash across our operating LLCs by moving to a concentration account with ZBA chains. That's real working capital, not accounting gymnastics."

Jonas Weidenhoefer — CFO, Multi-State Service Franchise

"The daily liquidity forecast caught a supplier payment that would have pushed us into the revolver two weeks out. We deferred it one cycle — saved the interest, kept the supplier happy."

Leila Okafor — Treasury Director, Consumer Products Company

"BAI2 straight into Kyriba cut our daily reconciliation from ninety minutes to under ten. The intraday drops at 11 AM let us release afternoon wires with confirmed balances."

Craig Dutta — Assistant Treasurer, Healthcare Network

What is cash management at Western Alliance Bank Business?

Cash management covers sweep accounts, master concentration accounts, daily / weekly / monthly liquidity forecasts, and ERP integration through BAI2 and ISO 20022. The modules sit on top of Commercial Checking and treasury services inside the business portal.

How does sweep configuration work in the business portal?

Target balance rules drive end-of-day movement. Investment sweep to MMF or treasury. Loan sweep toward revolver pay-down. Sub-account sweep to concentration. Priority rules resolve multi-sweep conflicts. Daily sweep reports document every movement. Material rule changes require dual authorization under full audit log.

What is a concentration account and why do multi-entity companies need one?

A master operating account that receives nightly sweeps from subsidiary ZBAs — consolidates multi-entity cash without losing per-entity signatory controls. Franchise operators, holding structures, and multi-state businesses benefit most. Pairs with Commercial Checking and ZBA chains.
