Construction Treasury Management: Cash Concentration, Bank Relationships, and Working Capital Optimization

Construction treasury management coordinates cash across projects, optimizes bank relationships, manages working capital, and supports financial operations beyond basic AP/AR. Cash concentration consolidates funds across operating accounts. Bank relationship management negotiates fees and services. Working capital optimization manages timing of receivables and payables. Short-term investments earn return on idle cash. Lines of credit support cash flow gaps. Treasury is distinct from accounting — forward-looking cash management vs historical accounting. Understanding treasury helps construction firms optimize financial operations.

This post covers construction treasury management.

Cash Concentration

Cash concentration aggregates funds:

Cash concentration aggregates funds for visibility and management. Multiple project bank accounts common in construction (job-specific accounts, owner trust accounts). Sweep to concentration account daily moves balances. Centralized payment processing from concentration account. Visibility across operations supports decisions. Investment of idle balance earns return. Specific structures vary — single concentration, multiple by region, etc. ZBA (Zero Balance Account) automatically sweeps balances daily.

Bank Relationships

Bank relationships strategic:

Bank relationships strategic. Primary banking relationship handles substantial transactions. Multiple banks for redundancy and negotiating leverage. Treasury management services from primary bank — lockbox, ACH, positive pay, etc. Lending relationship for line of credit, term loans. Surety relationship coordination — bonding capacity affects banking. Specific to firm size — substantial firms have multiple banks; smaller may have one. Negotiated fees and services for substantial volume.

Working Capital

Working capital management critical:

Working capital management critical for construction. Accounts receivable from owners (often 30-90 days). Accounts payable to subcontractors and suppliers (manage timing carefully). Retainage substantial in construction (5-10% withheld until completion or beyond). Cash flow timing affects project funding. DSO (Days Sales Outstanding) tracks AR collection. DPO (Days Payable Outstanding) tracks payment timing. Net working capital position. Specific to project mix — fast-pay owners vs slow-pay affect substantially.

Payment Timing

Payment timing optimizes cash:

Payment timing optimizes cash position. Pay terms negotiated (net 30 standard, sometimes net 60, 90 with substantial vendors). Payment scheduling per terms — don't pay early without discount. Discount capture when economic (2/10 net 30 produces ~36% annualized return). Float optimization through legal payment timing strategies. Specific to vendor relationships — paying late hurts relationships and pricing. Balancing cash management with vendor relationships.

Short-Term Investment

Short-term investment of idle cash:

Short-term investment of idle cash earns return. Money market accounts liquid with modest yield. Treasury bills government-backed short-term. Commercial paper investment-grade short-term. Certificates of deposit (CDs) for known holding periods. Specific to risk tolerance — construction needs liquidity, conservative typical. Liquidity considerations critical — cash needs can be sudden. Yield vs accessibility tradeoff balanced.

Lines of Credit

Lines of credit support operations:

Lines of credit support operations. Operating LOC provides flexibility for working capital needs. Substantial capacity supporting cash flow during slow collection periods. Borrowing base sometimes ties LOC to accounts receivable. Specific lender requirements (financial covenants, reporting). Negotiated rates based on relationship and credit. Reporting to lender (financial statements, borrowing base certificates). Specific to firm needs and credit profile.

Specific Construction Issues

Construction-specific treasury issues:

Construction-specific treasury issues. Project trust accounts required in some states (Texas, others). Owner-funded escrow on some projects. Joint check arrangements for substantial subcontractors. Lien waivers and payment timing coordination. Retainage release timing affects working capital substantially. Bonding affects credit availability — surety requires adequate working capital and credit. Specific to project structure and funding.

Bottom Line

Construction treasury management coordinates cash across projects, optimizes bank relationships, manages working capital, and supports financial operations. Cash concentration aggregates for visibility. Bank relationships strategic. Working capital management critical. Payment timing optimizes cash. Short-term investment earns return on idle cash. Lines of credit support operations. Construction-specific issues including trust accounts, retainage, bonding affect treasury. For construction firms at scale, treasury management produces substantial financial benefit. Quality treasury function with appropriate oversight supports financial performance and operational flexibility. Often underinvested in mid-size construction — worth attention for firms above $50M revenue.
