Should Your Holding Company Pool Cash or Keep It Separate?

Centralizing treasury at the parent level means the parent can see and deploy the group's full cash position at once, which matters most when one subsidiary is cash-rich and another needs a short-term infusion, since the parent can move money between them without an external loan or a delay waiting for board approval at the subsidiary level. It also gives the parent stronger negotiating position with banks, since a larger combined balance typically earns better terms than several smaller ones negotiated separately.

The cost is added complexity: intercompany loans need documentation, and each subsidiary's own liquidity picture becomes harder to see clearly without pulling it back out of the consolidated view.

Letting each subsidiary manage its own cash keeps that entity's liquidity position transparent and self-contained, which matters if you're planning to sell one subsidiary independently, if a subsidiary operates in a regulated industry that expects to see its own standalone reserves, or if you simply want each business unit's leadership to feel direct ownership over their own numbers.

The cost is that idle cash at one subsidiary can't easily help fund a shortfall at another without going through a more formal intercompany process, and the group as a whole doesn't get the negotiating benefit of one large, pooled relationship.

Payables days norms vary a lot by industry, from roughly two to three weeks in fast-turnover sectors like restaurants up to nearly two months in some services and healthcare-support segments¹. If your subsidiaries operate in genuinely different industries with different natural payables cycles, centralizing AP payment timing at the parent level can create friction, since a payment cadence that fits one subsidiary's vendor relationships might be wrong for another's.

This is a concrete, operational reason some groups keep AP execution decentralized even while centralizing the cash pooling decision itself, treating the two as separate questions rather than one bundled choice.

Many holding companies end up somewhere between the two extremes: cash pooling for the reserve and strategic tiers, where the negotiating and yield benefits of scale matter most, while leaving each subsidiary's day-to-day operating account and AP execution decentralized, where local relationships and payment cadence matter more. This hybrid captures most of the pooling benefit without forcing every operational decision through the parent.

Write down explicitly which tier is pooled and which is decentralized, since without that clarity, individual decisions tend to drift toward whichever approach is more convenient in the moment rather than following a consistent structure.

A hybrid structure usually follows these rules:

• Pool the reserve and strategic tiers centrally, where scale improves bank terms and yield.
• Leave each subsidiary's day-to-day operating account and payables execution local, where vendor relationships and payment cadence matter more.
• Document every intercompany transfer as a loan or capital contribution with stated terms, not an informal transfer reconciled later.
• Write the split down so it stays consistent rather than being decided case by case.

Whichever structure you choose, any cash that moves between the parent and a subsidiary, or between two subsidiaries, needs a documented intercompany loan or capital contribution with stated terms, not an informal transfer that gets reconciled later. This matters for tax purposes, for a future audit, and for a future sale process where a buyer's diligence team will specifically look for undocumented related-party cash movement.

Assign one person, usually the group controller, to own the intercompany documentation regardless of which pooling model you pick, so it doesn't fall through the cracks between two subsidiaries who each assume the other is tracking it.

Imagine one subsidiary needs $300,000 quickly to cover a payroll gap while another is sitting on a large surplus. Under centralized pooling, the parent can move that cash the same day against a documented intercompany note. Under a fully decentralized structure, that subsidiary either needs its own credit line already in place or has to wait on a slower, more formal approval process between two boards.

Decide which of those two outcomes you're comfortable with before the scenario actually happens, not while it's happening, since the decision made under time pressure is rarely the one you'd have chosen with a clear head.
