Why the client portfolio should be treated as an investment
In many Swiss SMEs, revenue growth masks a structural problem: part of the portfolio absorbs productive capacity, causes collection delays, and leaves little margin after direct costs, recurring discounts, and administrative time. Continuing «so as not to lose volume» often means accepting operating income below the cost of capital and staff.
Rationalizing does not mean cutting clients at random. It means measuring profitability through analytical income statements, defining acceptable thresholds, and exiting relationships in an orderly way that do not support the business model — while respecting contracts, relationships, and accounting obligations typical of Swiss contract law under the Code of Obligations.
This guide offers a practical path for owners and finance managers: from calculating the «true» margin per client to planning the impact on liquidity and headcount, with tools that integrate into the ordinary accounting cycle.
Accounting margin vs economic margin per client
The first mistake is looking only at gross margin on the invoice. To decide whether a client stays in the portfolio you need fully loaded costs and behavior indicators:
| Item | What to include | Risk signal |
|---|---|---|
| Net revenue | Revenue net of discounts, credit notes, and returns | Structural discounts > 5–10% of client revenue |
| Direct costs | Materials, subcontractors, variable licenses, shipping | Gross margin < industry average or below internal threshold |
| Internal time | Sales, production, support, extra revisions (fully loaded hourly cost) | Out-of-scope requests not billed |
| Administrative cost | Reminders, reconciliations, complaint handling, VAT adjustments | DSO (days sales outstanding) well above average |
| Credit risk | Bad debt, cost of capital tied to unpaid receivables | Payments repeatedly beyond contractual terms |
With cost-center or job-order accounting — even in simplified form — you can allocate hours and overheads to major clients. Software such as Accountex links invoices, payments, and analytical entries, so management sees not only period profit but also how margin is concentrated in a few commercial relationships.
Segmentation matrix: four operational quadrants
Before terminating a contract, classify each significant client (for example above 2–3% of revenue or above a monthly hours threshold) in a margin × complexity matrix:
High margin, low complexity
Clients to protect and possibly expand. Avoid automatic discounts; invest in standardized service to maintain efficiency.
High margin, high complexity
Renegotiate scope, pricing, or minimum fee. Document variations with confirmed orders for accounting traceability and correct VAT.
Low margin, low complexity
Candidates for gradual exit or move to a «self-service» price list. Capacity savings often exceed lost revenue.
Low margin, high complexity
Top priority for planned exit: they consume team capacity and liquidity. Consider notice period, transition to a competitor, or immediate scope reduction.
Planning exit without a liquidity shock
Losing a significant client reduces income but not always fixed costs at the same time. Before announcing termination, model a 6–12 month cash-flow scenario: revenue lost month by month, variable costs that drop, fixed costs that remain (rent, salaries, pension fund contributions, social security), any indemnities or contract-closure work.
Goal: maintain a liquidity cushion (a common prudent rule in SMEs: cover at least 2–3 months of operating cash costs) even in the worst month of the plan. If exit coincides with a weak season, shift the effective date or negotiate a paid transition period to clear work in progress and collect open receivables.
Recommended sequence (logical order)
- Quantify economic margin and outstanding receivables for the target client.
- Estimate freed capacity (equivalent FTE hours) and timing of avoidable costs.
- Identify replacements: upselling to «green» clients, new contracts already in the pipeline, reduced overtime.
- Set a «cash-neutral» date — when cumulative net flow does not worsen beyond the approved threshold.
- Align the plan with the bank or lenders if covenants or credit lines are tied to revenue.
Contractual and accounting aspects in Switzerland
B2B commercial relationships are generally governed by supply or service contracts, general terms and conditions (GTC), and, if agreed, term and tacit renewal. The Code of Obligations (CO) requires compliance with agreed terms and conduct consistent with the principle of good faith (Art. 2 CO); for ongoing service contracts, the termination rules of Art. 404 CO apply (termination generally at any time, subject to protection against untimely termination). Notice periods, penalties, or minimum terms must be verified before any formal communication — for service contracts, a non-waivable minimum term may be invalid.
| Situation | Prudent approach | Accounting impact |
|---|---|---|
| Open-ended contract with notice | Respect the notice period; for services verify termination is not untimely (Art. 404 CO); deliver work in progress; close open orders | Final invoice and accrual adjustments; check VAT on last services |
| Fixed-term contract nearing expiry | Do not renew; communicate within GTC deadlines | No extraordinary provision unless penalties are probable |
| Client requests extra work after internal decision | Offer full rates or reasoned refusal; avoid unpaid transition work | Written order before execution — consistent with audit trail |
| Disputed receivables | Amicable settlement or ordinary procedure; do not cancel issued invoices without basis | Assess receivable impairment under the prudence principle (Swiss GAAP FER) |
Document decisions (internal minutes, timestamped emails) for consistency with any limited or ordinary audit. Revenue corrections for billing errors follow Swiss accounting rules on the matching principle.
Team and capacity: avoiding an operational void or burnout
Exiting a client frees time but can create anxiety if the team sees the move as a prelude to layoffs. Communicate internally the «why» in terms of economic sustainability and quality of work, not as commercial failure. Show where capacity will be redeployed: training, high-margin clients, less overtime, accounting automation projects.
Plan a structured handover: single point of contact with the client, cutoff date for tickets and deliveries, document archive for the retention period required by federal law (accounting and VAT; typically ten years). Avoid leaving junior staff to handle difficult conversations without briefing and support from management.
Before announcing to the client
- Align sales, operations, and administration on message and dates.
- Check holidays, production peaks, and the client’s fiscal deadlines (e.g. year-end closes).
- Prepare internal FAQs on residual tasks and post-exit support limits.
After exit
- Reallocate hours to qualified sales pipeline, not generic busywork.
- Review monthly hour budget and personnel costs (Swiss GAAP FER: cost/revenue correlation).
- Monitor average margin and portfolio DSO for three months.
Alternative to exit: pricing reset and minimum engagement
In some cases a structured last attempt before termination pays off — especially if the client occupies strategic niches or references. Propose in writing a new price list, a minimum monthly fee, or a bundle with defined scope; set a deadline for acceptance.
If they accept, update contract terms and master data in accounting (new VAT codes if the type of service changes, new payment terms). If they refuse, exit is already prepared on the financial plan and the team has experienced a fair, data-driven process.
For clients with a mix of products at different margins, consider selective discontinuation of unprofitable lines while keeping only what meets the threshold — it reduces revenue shock compared with losing the entire relationship.
Indicators to monitor after rationalization
Measure the effect of portfolio cleanup on four levers, ideally with monthly reporting from your accounting system:
| KPI | Formula / logic | Indicative SME target |
|---|---|---|
| Average contribution margin | (Revenue − variable costs) / revenue for the portfolio | Upward trend vs quarter before exit |
| Revenue concentration | Top 3 clients’ share of total | Below internal threshold (often < 40–50%) |
| Non-billable hours | Internal hours / total hours by area | Declining after exiting complex clients |
| Cumulative net cash balance | Operating inflows − outflows, rolling 13 weeks | No period below defined cushion |
Operational checklist before closing a relationship
- 1.Negative economic margin or below threshold for at least two consecutive periods, confirmed by accounting analysis.
- 2.Liquidity scenario approved; outstanding receivables included in collection plan.
- 3.Notice and penalties verified; work in progress and handover documented.
- 4.Team informed; capacity reassigned within 30 days of effective date.
- 5.Client informed in a professional tone; channel consistent with contract (registered mail if required).
- 6.Update master data, price lists, and reporting in Accountex or your current system.
Rationalizing the portfolio is a management lever on par with controlling fixed costs and billing discipline. With reliable numbers, transitions that respect Swiss contract law, and attention to treasury, SMEs can free margin and capacity without traumatizing the organization or cash flows — and strengthen the base for healthier growth in coming fiscal years.
