Why discounts require explicit rules
In many Swiss SMEs, trade discounts remain a grey area: sales grants a 12% rebate to close a deal, the project manager adds another 5% to compensate for a delay, and at quarter-end no one knows how much margin was given away. Without approval thresholds and minimum margins, revenue growth can mask a structural deterioration in profitability.
Discount discipline is not just a commercial issue. In Switzerland, every price reduction must be traceable in accounting (Art. 957 et seq. CO), correctly presented in the income statement under Swiss accounting standards (Swiss GAAP FER or, for listed companies, IFRS), and documented for VAT purposes (VAT Act/MWSTG). A discount recorded incorrectly or without justification can alter the tax base, complicate year-end closing, and weaken internal control in front of an auditor.
This guide offers a practical framework — adaptable to trade, services, and manufacturing — for defining who can approve which discount, up to what threshold, with what minimum contribution margin, and how to record every exception in an auditable way. The goal is not to eliminate commercial flexibility, but to make it measurable and compliant.
Types of discount and impact on margin
Before setting thresholds, it helps to classify discounts by type and risk. Each category requires different rules and approval levels:
Trade discount (rebate)
Agreed reduction on the list price at the time of order or quotation. Examples: volume discount, loyalty discount, time-limited promotional price. Direct impact on net revenue and unit contribution margin.
Typical risk: accumulation of invisible discounts (list price − discount A − discount B) that erodes margin without appearing in standard reports.
Cash discount (early payment discount)
Reduction conditional on meeting a payment deadline (e.g. 2% within 10 days). In accounting, it may be recorded as a financial expense or as a reduction in revenue, depending on company policy and the chosen presentation.
Note: a cash discount not granted does not generate additional revenue; it must be distinguished from structural trade discounts.
Volume discount / tier pricing
Decreasing prices as purchase volume increases. Requires a pre-approved matrix with minimum margins per tier, not case-by-case decisions.
Ideal for automating approval: if the quantity/price combination complies with the matrix, no escalation is needed.
Exceptional discounts and compensations
Credit notes for complaints, year-end discounts, compensations for invoicing errors or delivery delays. These are the most risky items for internal abuse and correct accounting allocation.
They always require senior approval, written justification, and a link to the original document (order, invoice, ticket).
Approval threshold matrix
The matrix below is a starting point for SMEs with 5–50 employees. Adapt the percentages to your industry and average margin; what matters is that each level has a clear ceiling and a defined superior:
| Role | Max. single discount | Max. cumulative discount | Min. margin required | Documentation |
|---|---|---|---|---|
| Sales / consultant | 5% | 8% on the same order | ≥ 35% contribution margin | Standard reason (competition, volume) |
| Sales manager | 12% | 15% cumulative | ≥ 28% | Competitor comparison or customer annual plan |
| Management / CEO | 20% | 25% cumulative | ≥ 20% (or documented strategic break-even) | Business case with impact on LTV and pipeline |
| Pricing committee (optional) | Above 20% | Unlimited exceptions | Case-by-case assessment | Quarterly minutes + written approval |
Fundamental rule: cumulative discount is always calculated on the list price, not on the already discounted price. If the list price is CHF 10'000 and 8% + 5% are applied, the cumulative discount is 13%, not 12.6%. This distinction prevents small "innocent" discounts from stacking beyond the tolerable margin.
Minimum margins: how to calculate them correctly
Approval thresholds must be based on a realistic contribution margin, not gross revenue. For every discounted proposal, calculate:
Contribution margin (%) = (Net price − Direct variable costs) ÷ Net price × 100
Net price includes all planned trade discounts but excludes VAT. Variable costs include materials, direct labour, variable commissions, and order-specific fulfilment costs.
Example — distribution SME in Ticino: list price CHF 2'500, variable costs CHF 1'450. Base margin: 42%. A sales rep requests a 10% discount → net price CHF 2'250, margin CHF 800 → 35.6%. Within the sales manager threshold (≥ 28%), automatic approval. With an 18% discount → price CHF 2'050, margin CHF 600 → 29.3%: escalation to management required.
Watch out for hidden costs: shipping included, unbilled consulting hours, free extended warranty. If these are not included in variable costs, the real margin falls below the threshold even with a "formally" acceptable discount. Include a checklist of ancillary costs before approval.
For strategic customers, assess margin at annual contract level (customer lifetime margin) rather than on a single order, but still record every discount on the commercial document to maintain traceability.
Accounting tracking under Swiss standards
Under Swiss ordinary accounting, revenue is presented net of trade discounts granted (Swiss GAAP FER — standard chart of accounts, account 3xxx Net revenue). Recording must allow reconstruction of list price, discount, and net revenue for every relevant transaction.
| Transaction | Recommended recording | Note |
|---|---|---|
| Discount on invoice | Net revenue; "Trade discount" line visible on invoice | Preferred method — maximum transparency |
| Subsequent discount (credit note) | Partial revenue reversal (account 3xxx) or dedicated discount account | Requires reference to the original invoice |
| Cash discount taken | Revenue reduction or financial expense (consistent policy) | Apply the same method throughout the financial year |
| Discount in kind (free goods) | Warehouse outflow + revenue allocated at fair market value | Relevant for VAT and margins |
Art. 958 CO requires orderly accounting that allows verification of every transaction. Create at least one analytical account or cost centre "Trade discounts" to monitor the total amount given up by period, customer segment, and sales rep. At year-end, total discounts must reconcile with the delta between list-price turnover and recorded net revenue.
If you operate with more than one legal entity (e.g. holding and operating subsidiary), maintain uniform discount and recording policies to avoid informal transfer pricing between group companies.
VAT on discounts and tax compliance
Under the VAT Act (MWSTG; Art. 24), discounts and allowances that reduce the consideration actually received reduce the tax base if they are clearly indicated on the invoice or on a correction document (credit note) linked to the original transaction. The discount must be identifiable: percentage or amount, commercial justification, and reference to the good or service.
If you grant a discount after issuing the invoice, issue a VAT-compliant credit note and record the correction in the appropriate tax period (Art. 41 VAT Act). Do not silently amend invoices already sent to the customer or already included in a periodic VAT return without formal correction.
For the standard rate (8.1%), special rates — 2.6% for categories eligible for the reduced rate and 3.8% for accommodation services — and exempt transactions, verify that the discount reduces the tax base in the correct category. An allocation error may only surface during an audit by the Federal Tax Administration (FTA).
Conditional discounts (cash discounts) that the customer does not obtain due to late payment do not require a VAT correction: revenue remains as invoiced. Document the condition on the sales document.
Internal controls and audit trail
An effective discount policy rests on four control pillars, particularly relevant if your SME has opted out of limited audit (where permitted under Art. 727a para. 2 CO, for example with no more than 10 full-time equivalent positions on average per year):
- 1.Segregation of duties: whoever approves the discount must not be the sole person responsible for accounting entries. In small companies, at least document dual electronic signatures on orders above threshold.
- 2.Digital audit trail: every discount must leave a trace — who requested it, who approved it, date, percentage, reason, margin calculated at the time of approval.
- 3.Monthly reports: average discount by sales rep, product segment, canton; comparison with budget. Automatically flag transactions below minimum margin.
- 4.Quarterly review: management analyses exceptions above threshold and updates price lists or matrices if recurring discounts indicate off-market pricing.
Recommended KPIs for the management board
- • Weighted average discount on gross turnover (target: < 5% for mature B2B SMEs)
- • Percentage of orders approved above the sales rep threshold
- • Average post-discount contribution margin by product line
- • Average approval time for exceptions (process efficiency)
- • Variance between list-price revenue and recorded net revenue
Operational workflow: from quotation to closing
Implement the process in five steps, integrating it into your accounting software and CRM:
Price lists and pre-approved matrices
Define standard prices and volume discounts already validated against minimum margin. Load matrices into your ERP to automatically block non-compliant combinations.
Discount request with margin calculation
The quotation shows list price, requested discount, resulting margin, and required approval level. No quotation goes out without this calculation.
Tracked approval
Email or in-app workflow with timestamp and mandatory justification. For discounts > 15%, attach competitive comparison or customer plan.
Compliant invoicing
The invoice shows list price, discount applied, and net amount excluding VAT. Accounting software records net revenue and the analytical detail of the discount.
Monthly closing and reconciliation
Reconcile approved orders, issued invoices, and accounting entries. Flag discounts applied on invoices without prior approval — a sign of control bypass.
How Accountex supports discount governance
Accountex lets you link quotations, orders, and invoices in a single flow, keeping the applied discount visible on every document. Cost centres and analytical categories allow you to extract reports on discounts by period, customer, and sales owner, facilitating monthly closing and preparation of data for the auditor or VAT return.
Configure alerts when a sales document falls below the defined minimum margin, and use user permissions to limit who can change prices and payment terms. This way, the approval policy does not remain a forgotten PDF document, but a rule applied daily in the order-invoice-collections cycle.
For SMEs with multiple cantonal locations, consolidated reporting helps identify divergent commercial practices — for example, higher average discounts in one canton — and align price lists and thresholds before margin erosion becomes structural.
