Hello everyone,
Today, I would like to share some practical insights on how Accruals can be effectively used to manage fixed costs.
Fixed costs include not only personnel expenses but also advertising, recruitment, training, consulting, and many others. The challenge is that the actual month in which these costs occur often differs from the month assumed in the budget.
For example, even if the budget assumes “5 million yen will be spent in July,” the actual spending may be brought forward to June, postponed to October, or even carried over to the following year.
This timing mismatch creates P&L budget variances and leads to unproductive back-and-forth discussions with Group management. Moreover, if costs are booked only when they actually occur, fixed costs fluctuate significantly month by month, distorting break-even analysis and fixed-cost trend analysis.
🟦 Why I Recommend Using Accruals
I believe the most rational approach is to use Accruals to allocate fixed costs evenly across months— in the budget, in the forecast, and in actual processing.
Example: Annual advertising budget of 5 million yen, with actual spending occurring in July.
Budget: Allocate evenly from January to July (approx. 710,000 yen/month)
FCST: Same allocation
Actuals: Record 710,000 yen each month as an Accrual and reverse the accumulated 5 million yen in July when the cost actually occurs
With this approach, Budget, FCST, and Actuals move in perfect alignment.
Group management does not look at the B/S. What they look at is P&L budget variance. This is why Finance must operate in a way that avoids monthly fixed-cost variances.
🟦 Accruals Create “Good Surprises” and Prevent “Bad Surprises”
If you rely solely on the timing of actual occurrence:
Costs appear in unexpected months
Budget variances suddenly emerge
Group management starts asking “Why this month?”
This is a “Bad Surprise,”something particularly disliked in Western companies.
On the other hand, if Accruals are booked according to budget:
If actual spending is lower than budget → Reverse the excess Accrual in December and increase profit (Good Surprise)
If actual spending is zero → Simply reverse the full amount in December
During budget season (Sep–Nov) → You can justify next year's budget based on “this year's cost + α”
Excess Accruals → Serve as a buffer for unexpected events
This is a sound and rational management accounting practice that enhances the stability and predictability of the business.
🟦 Accruals Themselves Become a Budget Management Mechanism
The act of booking Accruals every month naturally forces both Finance and the business to stay aligned with the budget.
Book according to budget
FCST follows the same pattern
Actuals follow the same pattern
No variances
Almost zero explanation cost
This is one of the simplest and most powerful ways to systematize budget management.
🟦 This Is Where a Subsidiary Controller Demonstrates Real Capability
Smoothing fixed costs, applying Accruals appropriately, creating Good Surprises, preventing Bad Surprises, securing next year's budget, and preparing for unforeseen events:
— These are all core competencies of a strong subsidiary Controller.
Western Group management evaluates:
Reliability of budget control
Stability of variance management
Ability to avoid Bad Surprises
Ability to generate Good Surprises
Your ability to execute these practices consistently is a key indicator of your capability as a Controller.
Accrual-based fixed cost management is one of the clearest ways to demonstrate a subsidiary's management capability and is a powerful tool for earning the trust of the Group.
