Why buying a customer portfolio is not a «simple» expense
In many Swiss SMEs — agencies, professional firms, service businesses, B2B trade — growth often comes from acquiring a customer portfolio, a business unit, or recurring contracts. The price paid to the transferor is not only for tangible assets: it often includes commercial relationships, local reputation, and future revenue potential, i.e. elements that in accounting may translate into goodwill or other intangible assets, such as an identifiable customer list.
Under the Swiss Code of Obligations (CO) and Swiss accounting standards (in particular Swiss GAAP FER), recognition depends on what you legally acquire, how the contract is drafted, and how much of the price can be allocated to specific components. A common mistake is charging the full amount to «general expenses» or «purchase of goods», losing traceability in the balance sheet and creating inconsistencies with the corporate income tax return.
This guide covers the most common transaction types, capitalisation criteria, accounting amortisation, and relevant federal tax guidelines for corporations and sole proprietorships, with practical pointers for those using accounting software such as Accountex to keep assets, amortisation, and due diligence documentation in order.
What you are really buying: three typical scenarios
Before posting the first journal entry, it is worth classifying the transaction. In practice three models are distinguished, each with different implications for goodwill and customer lists:
Customer list / database only
You acquire names, contacts, order or mandate history, without taking on employees or lease contracts. Value is tied to data and relationships, also subject to Swiss data protection law (FADP / revDSG).
Business unit or portfolio with contracts
Supply contracts, subscriptions, licences, or staff may be involved. The price must be split among identifiable assets, liabilities assumed, and the remainder (goodwill).
Acquisition of the entire business
Transfer of shares (share deal) or of assets (asset deal). In an asset deal or business-unit acquisition, residual goodwill from the price allocation is capitalised as intangible fixed assets; in a share deal the acquirer generally records the participation at acquisition cost, while goodwill matters mainly in consolidated financial statements (Swiss GAAP FER 30).
Customer list, goodwill, and expenses: operational comparison
The accounting choice is not purely technical: it affects amortisation, annual profit, and the tax base. Orientational summary for SMEs applying nominal-value accounting (CO / FER):
| Item | Purchased customer list | Goodwill (acquisition residual) | Period expenses (not capitalisable) |
|---|---|---|---|
| Nature | Identifiable intangible asset (if separable and measurable) | Excess of price over net value of identifiable items | Acquisition costs, one-off advisory, generic marketing |
| Capitalisation | Yes, if useful life > 1 year and amount is material | Yes for consideration-based acquisition of a business or business unit | No — to income statement in the period |
| «Internal» goodwill | Not applicable (external acquisition) | Not capitalisable if generated internally | — |
| Accounting amortisation | Systematic over useful life (often 3–10 years, documented) | Swiss GAAP FER 10/30: systematic amortisation; check for impairment | — |
| Typical account (example) | 1300 Intangible assets — sub-account «Customer portfolio» | 1300 Goodwill | 6200 Administrative expenses or 6500 Marketing expenses |
| Documentation | Transfer agreement, FADP privacy notice, valuation or appraisal | Purchase price allocation (PPA) schedule | Supplier invoices, expense receipts |
Valuation and purchase price allocation
The consideration agreed with the seller must be broken down in a defensible way, especially if the cantonal tax authority or an auditor asks for detail. Common methods in SMEs:
- Revenue or margin multiple of the portfolio (e.g. three-year average revenue × sector coefficient), useful as a negotiation starting point.
- Discounted cash flow on expected revenue from acquired customers, net of churn and marginal costs.
- Purchase price allocation: fair value assigned to contracts, brand, customer list, equipment; the remainder is goodwill.
Watch the useful life
For a customer list, useful life should reflect how long you will realistically retain those relationships (not the legal term of the data transfer contract). An amortisation schedule that is too long inflates assets and understates period costs; one that is too short weighs on profit. Document assumptions and annual reviews in your accounting software’s amortisation file.
Journal entries: examples for an SME
Account numbers follow a typical Swiss chart of accounts; adapt them to your setup in Accountex. Example amount: CHF 120,000 for a customer portfolio (CHF 80,000 allocated to the list, CHF 40,000 to residual goodwill from included contracts).
1. Payment to the transferor (VAT: check taxability component by component)
In Switzerland, transfer of a business or business unit is not «automatically» exempt as a single supply (unlike some foreign regimes); individual elements may be taxable. Where the conditions are met, the notification procedure under Art. 38 VAT Act avoids cash-flow impact of VAT on the business transfer, without replacing analysis of each line item. Clarify on the invoice what is transfer of goods, services, or a going concern. Simplified entry at closing:
Debit 1300 Intangible assets — customer portfolio 80,000
Debit 1300 Goodwill 40,000
Credit 1020 Bank 120,000
2. Annual amortisation (e.g. 8 years list, 5 years goodwill — aligned with tax plan)
Debit 6800 Amortisation of intangibles 18,000
Credit 1300 (proportional shares) 18,000
Set up schedules and recurring entries to avoid year-end omissions.
Swiss tax: corporate income tax and critical points
For federal direct tax and cantonal profit tax, the general principle of massgeblichkeit (tax alignment with commercial accounts) applies: amortisation booked in the accounts is deductible if justified by commercial use (Art. 62 paras. 1 and 2 DBG; analogous cantonal provisions). Goodwill from the consideration-based acquisition of a business or business unit may be recorded separately and amortised for tax purposes over its probable useful life — in administrative practice often around five years, unless a different documented rationale applies (FTA circular on amortisation of fixed assets). A separately capitalised customer list follows intangible amortisation rules if consistent with the commercial balance sheet. In a share deal, separate goodwill is not amortised on the individual balance sheet; treatment of the participation applies instead.
Cantonal taxes follow commercial profit with adjustments; any differences between accounting amortisation and tax deduction must be recorded in the tax reconciliation (Mehr-/Minderrechnung). For sole proprietorships and partnerships, the logic is similar on business income, with progressive cantonal rates on personal income.
VAT does not treat acquisition of a business as a whole as «one exempt supply» in every case: in mixed transactions, invoices must separate goods, services, and any transfer of real estate. Between taxable persons, transfer of a business or business unit may fall under the notification procedure under Art. 38 VAT Act (threshold of CHF 10,000 of theoretical tax or close economic link). Errors here can lead to disputes over input tax and the seller’s tax base.
Where the transferor (company or individual) realises capital gains, classification of the transaction (business income vs capital gain) affects taxation and withholding; the acquirer should retain the contract, declarations, and proof of payment for possible later audits.
Contract, due diligence, and data protection
A customer portfolio is also a set of personal data. Beyond accounting:
Contractual clauses
- Warranty of data ownership and marketing consents where relevant
- Non-compete and non-solicitation (duration and territorial scope)
- Variable consideration tied to customer retention (earn-out) and its accounting
- Assisted transition and contract assignment with change-of-control clauses
Document trail in accounting
- Attach PPA, appraisal, and contract to fixed-asset entries
- Note amortisation start date (as a rule from economic usability)
- Monitor post-acquisition churn for possible impairment
Transaction closing checklist
| Step | Action |
|---|---|
| Classification | Define whether asset deal, business unit, or data/contracts transfer only |
| PPA | Allocate price among customer list, contracts, equipment, and goodwill |
| Capitalisation | Capitalise and set up amortisation plans in Accountex |
| Tax | Align deductible amortisation and accounting/tax reconciliation |
| VAT and transferor | Check VAT liability, invoicing, possible notification procedure (Art. 38 VAT Act), and seller obligations |
| FADP | Update privacy notice and legal basis for processing acquired data |
Summary for entrepreneurs and trustees
Buying a customer list or commercial portfolio can accelerate growth, but the price paid should be treated with the same rigour as investment in physical capital: capitalise where CO/FER criteria require it, plan amortisation, and stay consistent with the tax return. Separating customer list and goodwill is not optional when due diligence allows it: it improves transparency for banks, shareholders, and authorities.
With digital processes — archived contract, automatic amortisation schedule, tax reconciliation linked to the balance sheet — you reduce the risk of adjustments and keep the impact on cash flow under control. For complex situations (earn-out, multiple cantons, cross-border transfer), support from a trustee experienced with SMEs remains the safest choice.
