Day One treasury and cash management is the discipline of making sure Newco can fund payroll, pay critical suppliers, collect receivables, and maintain visibility into liquidity from the first business hour. The work sits inside the broader Day One readiness framework and is the workstream PE operating partners watch most closely because cash mistakes compound fastest. Treasury readiness rarely fails publicly. It fails on the bank reconciliation three weeks in.
Newco needs a bank account structure designed to its operating reality, not inherited from the seller. The structure typically includes a main operating account, a payroll account, one or more collection accounts for major receivable flows, and a controlled disbursement account for AP. Multi-entity carve-outs need accounts per legal entity. International operations need local currency accounts in each operating jurisdiction.
The bank selection is made by day 30 of the runway. Most Newco buyers go with a primary bank that can support credit, treasury services, and operating accounts under a single relationship. The selection is driven by the credit facility, the geographic footprint, and the treasury workstation integration. The work runs alongside the credit agreement negotiation and the closing condition planning.
Signatory setup is the operational mechanic that ties the bank accounts to Newco governance. The corporate resolution names the authorized signers. The bank documentation lists the signers, their authority levels, and the dual approval requirements. The work is unglamorous and procedural. It is also the single most common source of Day One delays because banks have their own onboarding timelines.
Once accounts are open and signatories are in place, the accounts are funded. The funding is sized to cover the first payroll, the first round of critical AP, and a working capital buffer for the first 30 days. The treasury lead reconciles the funding plan with the closing flow of funds. The discipline mirrors carve-out treasury strategy.
Newco needs a 13 week cash forecast operational on Day One. The forecast is the primary tool for liquidity management in the first six months when historical data is thin and operating patterns are still settling. The forecast covers expected receipts, scheduled disbursements, debt service, and capital expenditure. The model is owned by the treasury lead and reviewed weekly with the CFO.
The forecast is built from the receivables aging, the AP forecast, the payroll schedule, and the debt service schedule. Where TSA settlements flow through the account, those are tracked as a separate line item with explicit timing assumptions. Where collections are still flowing to a seller lockbox under TSA, those are forecast against the sweep timing and reconciled monthly.
Liquidity controls are the structural backbone of the treasury function. The daily cash position report. The weekly cash forecast variance review. The monthly bank reconciliation. The quarterly treasury committee review. Each control is documented, named owner identified, frequency set. The controls run from Day One through stabilization.
Where Newco operates with a revolver, the borrowing base reporting is part of the Day One framework. The reporting is typically monthly with daily or weekly visibility into key collateral changes. The first borrowing base certificate is filed within the agreed timeframe after close. The work runs in parallel with the credit agreement compliance discipline.
Newco needs functional payment rails on Day One. ACH for vendor payments. Wire transfers for high value and time critical payments. Checks for the long tail. International wire capability for cross-border vendors. Each rail needs to be tested before Day One with a small live transaction to validate the routing and the approval workflow.
The disbursement controls are the discipline that prevents fraud and error in the first weeks. Dual approval on every wire above a defined threshold. Segregation of duties between payment initiation and payment approval. Daily reconciliation of disbursements against the AP register. Each control is configured in the bank platform and tested before cutover.
Positive pay is non negotiable for check disbursement. The bank receives the issued check register daily and rejects any check presented that does not match. The control eliminates the most common check fraud vector and is configured during account opening. Where checks are minimal, positive pay still runs because the cost is low and the protection is meaningful.
The disbursement workflow is integrated with the AP system. The procure to pay system generates the payment file. The bank platform receives the file. The dual approvers release the payment. The bank executes. Each step is documented and timestamped. The audit trail is preserved per the document retention policy. The pattern is consistent with the Day One readiness framework.
Customers need new remittance instructions on or before Day One. Where Newco changes legal entity, the bank routing changes too. Each customer is communicated in advance with the new ACH details, the new lockbox address, and the new wire routing. The communication is multi channel because customers rely on different channels for accounts payable.
A common interim approach is to maintain the seller’s lockbox under TSA for 60 to 120 days post-close. The lockbox sweeps daily to Newco’s operating account. The arrangement gives customers time to update their payment systems without breaking cash flow. The lockbox sweep timing and the reconciliation methodology are documented in the TSA service catalog.
Where customers continue to pay the seller after the lockbox transition, the collections team works the exceptions individually. The seller flags misdirected payments and remits them with weekly cadence. The reconciliation is tracked through the TSA settlement process. The work is mechanical and consumes more time than expected in the first 90 days.
The customer master file gets updated to reflect Newco’s ownership of the relationship. New invoices carry Newco’s legal name, new remit to address, and new tax identifiers. The first invoice cycle post close is monitored for customer questions and routing failures. The discipline is operational and visible in the daily cash position.
Most mid-market Newco buyers do not stand up a dedicated treasury management system on Day One. The function operates on a combination of bank portal access, ERP modules, and spreadsheet workflows. The work is to make the manual cadence sustainable for the first six to twelve months while a system selection decision matures.
The daily reporting pack covers the cash position by account, the receipts of the day, the disbursements of the day, and the projected closing position. The pack goes to the CFO and the treasury committee at a defined time each morning. The discipline of a daily pack at a consistent time forces the data quality that the treasury function depends on.
The weekly cadence adds the 13 week forecast update, the AP and AR aging review, and the variance analysis against the prior week forecast. The monthly cadence adds the bank reconciliations, the treasury committee meeting, the borrowing base certificate, and the covenant compliance check. Each cadence has a defined owner and a defined output.
A clean treasury and cash management readiness program produces a Newco where cash is never a surprise. The position is known daily. The forecast is reliable. The disbursements are controlled. The collections route correctly. The seamlessness is the goal. The work that makes it seamless is the discipline of the treasury workstream documented in the Day One readiness program.
