Why indirect costs matter for true profitability
In many Swiss SMEs, the income statement shows a positive profit, yet some product or service lines turn out to be loss-making once all the costs required to run them are taken into account. The difference often lies in indirect costs: expenses that support the entire business without being directly attributable to a single order, project or item.
Premises rent, administrative salaries, accounting software, insurance, legal advice, maintenance of shared equipment, energy for common areas: these are real, recurring costs. If you do not allocate them in a structured way, you risk underestimating the full cost of what you sell and setting prices that cover only the visible part of the work or production.
Allocating indirect costs is not about artificially inflating prices, but about making transparent how much each offering must contribute to keeping the business running. For entrepreneurs, finance managers and fiduciary firms advising SMEs, it is a management control tool that complements the bookkeeping obligations under the Swiss Code of Obligations (Art. 957 et seq. CO) and, where adopted, Swiss GAAP FER accounting standards.
Direct and indirect costs: an operational distinction
Before choosing an allocation method, it is worth classifying costs consistently month after month. Switzerland has no single mandatory schema for internal management, but the distinction is essential for accurate analysis and for discussions with auditors or tax advisers.
| Cost type | Definition | Typical examples in an SME |
|---|---|---|
| Direct | Attributable without ambiguity to a product, service or job | Raw materials, billed consulting hours, specific subcontracting, dedicated packaging |
| Indirect | Supports multiple activities or the entire organisational structure | Rent, back-office salaries, software licences, general marketing, depreciation of shared machinery |
| Semi-direct | Linked to an area but not to a single job | Production manager salary, company vehicle used in mixed ways, energy for the production department |
Semi-direct costs require a documented internal rule: for example, allocating the production manager's time across product lines based on recorded supervision hours. The goal is not absolute perfection, but consistently applying the same logic, so comparisons across periods and offerings remain meaningful.
Allocation methods suited to Swiss SMEs
Not every company needs complex models. For most SMEs with fewer than 50 employees, simple methods are enough, provided the chosen criterion reflects the main economic driver of each cost group.
Proportional allocation (single rate)
Add up all indirect costs for the period and allocate them using a single criterion: hours worked, direct personnel cost, revenue by line or units produced. Suitable for lean structures with few cost centres.
Example: CHF 48,000 in quarterly indirect costs ÷ 1,200 productive hours = CHF 40 of overhead per hour to add to the direct hourly cost.
Cost centre allocation
Create centres (administration, production, sales, IT) and first allocate common costs to each centre, then from centres to products or services. Useful when some lines require more administrative or logistical support.
Example: 60% of administrative costs go to service jobs with high contractual complexity, 40% to retail sales.
Activity-based costing (simplified ABC)
Identify specific drivers: number of quotes, shipments, machine setups, quality reviews. Each activity absorbs a share of overhead. More precise, but requires traceable operational data.
When to use it: manufacturing SMEs or B2B businesses with a mix of products that differ greatly in logistical or administrative complexity.
Full cost per job or project
Calculate the direct cost of the job and add an overhead share calculated on an annual basis and updated quarterly. Ideal for service businesses, installers, agencies and technical firms.
Caution: using an outdated coefficient is worse than not allocating at all: review it at least every quarter or after a structural change (new premises, hires, digitalisation).
How to calculate full cost without distorting prices
Full cost is the sum of direct cost and the allocated share of indirect costs according to a defined rule. It does not necessarily equal the selling price: the price also includes target margin, market positioning, commercial discounts and sales strategy.
The most common mistake in SMEs is confusing overhead recovery with maximising margin on every single line item. Allocation helps you understand the minimum plan for economic sustainability, not to justify uniform price increases.
Numerical example: mechanical workshop in German-speaking Switzerland
Monthly direct costs (production): CHF 62,000 (materials CHF 28,000 + operating salaries CHF 34,000)
Monthly indirect costs: CHF 23,000 (rent CHF 8,500, administration CHF 7,200, IT and maintenance CHF 4,800, insurance and other CHF 2,500)
Allocation base: machine hours used — 1,150 hours/month
Overhead coefficient: CHF 23,000 ÷ 1,150 = CHF 20/hour
Typical job (120 machine hours, materials CHF 3,600, direct labour CHF 4,200):
- Direct cost: CHF 7,800
- Overhead share: 120 × CHF 20 = CHF 2,400
- Full cost: CHF 10,200
- With a 25% target operating margin on full cost → minimum sustainable price approximately CHF 12,750
If the offer is priced at CHF 11,500 because "we cover the hours anyway", the business appears to be operating but silently erodes its ability to cover rent, administration and investment. Across dozens of jobs, the effect accumulates and shows up as pressure on liquidity at year-end, despite sufficient orders.
Choosing the right driver for each cost group
A single criterion for all indirect costs is often insufficient. The table below suggests practical pairings that reduce the most common distortions:
| Indirect cost group | Recommended driver | Rationale |
|---|---|---|
| Premises rent and utilities | Square metres occupied or hours of space use | Reflects the physical footprint of production, warehouse or office |
| Administration and accounting | Number of documents, active customers or revenue by line | More customers and greater administrative complexity generate more back-office work |
| IT and software | Active users or workstations per department | Licences and support often follow the number of users |
| Marketing and sales | Revenue by line or contribution margin | Commercial activities aim to generate revenue on specific offerings |
| Depreciation of shared plant | Machine hours or production cycles | Equipment wear is linked to actual use |
From full cost to pricing policy: avoiding the traps
Knowing full cost does not mean applying the same markup to every product. Some lines have different price elasticity, longer sales cycles or strategic value (reference customer, entry into a new market). Allocation provides the floor, not the ceiling, of the price.
Trap 1: overhead too high on non-productive hours
Including training, holidays or extraordinary maintenance in the denominator inflates the hourly cost. Separate billable hours from structural hours and use different bases for planning and pricing.
Trap 2: annual coefficient on a weak quarter
If volume falls but fixed costs remain, unit overhead explodes. Better to use an annual budget for planning and rolling actual costs from the last 3–6 months for tactical adjustments.
Trap 3: an "average" price
A single rate for simple and complex services subsidises difficult jobs. Define at least two or three complexity classes with distinct overhead coefficients.
For service SMEs, contribution margin (revenue minus variable costs) remains useful for short-term decisions; full cost becomes decisive for assessing whether to keep an offering, invest in automation or drop structurally loss-making segments.
Internal allocation and Swiss accounting: what goes on the balance sheet
In the income statement, accounting under Art. 959b CO presents costs by nature (personnel, rent, energy, depreciation) or by function. Allocation to products, jobs or profit centres is, in most cases, complementary management analysis to the official financial statements, not a separate mandatory line item in the official accounts.
In practice, this implies three consistent levels:
- Financial accounting: correct recording of supplier invoices, salaries, accruals and depreciation under the CO and, where applicable, Swiss GAAP FER.
- Management accounting: periodic allocation of indirect costs to jobs, products or departments with documented rules.
- Management control: comparison of planned full cost, actual cost and selling price to adjust price lists and offering mix.
Accounting software such as Accountex lets you link entries, cost categories and analytical reports without duplicating administrative work. The goal is a single source of truth: accounting data feeds both the financial statements and full cost calculation, reducing transcription errors and delays in monthly closing.
Gradual implementation in five steps
Map costs from the last financial year
Export recurring items from the income statement. Separate purely fixed costs (rent, insurance) from semi-variable costs (commissions, volume-linked energy). For a first analysis, 12 months of data is enough.
Define analysis units
Choose whether to allocate by product SKU, service family, job or customer. Fewer units means greater simplicity; more units means greater precision but more maintenance.
Set drivers and percentages
Document in a spreadsheet or internal note who approves the rules and how often they should be reviewed. Involve the operations manager: a driver chosen only by the accountant may ignore real production constraints.
Calculate and compare with current prices
For each main line, compare full cost and average selling price (net of discounts). Highlight offerings below the sustainability threshold and those with excessive margin relative to the market.
Integrate into the quarterly review cycle
Update coefficients, check variances and align quotes and price lists. Allocation is useful only if it lives in the commercial process, not if it remains an Excel exercise isolated from management.
Quick checklist before updating prices
- ✓Indirect costs for the period are complete (no significant items only in a private account or not recorded)
- ✓The chosen driver is measurable with data already available (hours, sq m, revenue, units)
- ✓Full cost has been compared with actual average price, not only with the theoretical list price
- ✓Strategic low-margin lines are identified consciously, not by calculation error
- ✓Management has validated the allocation rules and update frequency
- ✓New quotes use updated coefficients, not values from the previous financial year
An objective basis for stronger commercial decisions
Allocating indirect costs does not automatically turn a company into a rigid pricing machine. On the contrary: it makes cross-subsidies between offerings visible, clarifies which products or services truly support the structure and lets you negotiate discounts knowing how far you can go without eroding sustainability.
For a Swiss SME, the combination of reliable bookkeeping compliant with the CO, simple but consistent allocation rules and periodic review of coefficients is often enough to avoid the most costly distortions — prices too low on complex jobs and too high on efficient ones — without burdening the organisation with multinational-style models.
Starting with a subset of high-volume lines, refining drivers and data over a few quarters, then extending the method to the rest of the catalogue: that is the approach that offers the best balance between precision, team time and quality of entrepreneurial decisions.
