How do you translate "customer" into German?

Last reviewed: September 8, 2026

What are the best ways to translate "customer" into German?

The best translation of "customer" depends on who the customer is and what they are buying — German splits the concept across several distinct nouns:

• der Kunde / die Kundin / die Kunden — the default for anyone buying goods or services, from e-commerce shoppers to SaaS accounts. If you need one term for a support glossary, this is it.
• der Klient / die Klientin — clients of advisory and professional services such as consulting or social services; using Kunde here can read as too transactional for the relationship.
• der Mandant / die Mandantin — specifically the client of a lawyer, notary, or tax advisor; German legal and tax content that says Kunde instead signals unfamiliarity with the domain.
• der Gast / die Gäste — hospitality's word: hotels and restaurants address Gäste, not Kunden, and the wrong choice is immediately noticeable to native speakers.
• der Auftraggeber / die Auftraggeberin — the commissioning client in B2B, agency, and contract work, literally "the one who gives the order."
• der Verbraucher / die Kundschaft — Verbraucher means "consumer" and dominates regulatory and consumer-protection language; Kundschaft is the collective "clientele," a more traditional retail register.

How do support teams keep customer terminology consistent in German?

Consistency comes from deciding each term once and letting the platform enforce it, rather than re-litigating word choice on every ticket or article:

1. Record the decision as a glossary entry — Smartling's Terminology Directory stores each approved term with a definition, part of speech, linguistic variations, and Case Sensitive / Exact Match flags, so "Kunde" and its inflected forms are recognized in real sentences, not just as an isolated dictionary form.
2. Set the formality register once — decide whether your brand addresses customers as Sie (formal) or du (informal) and record it in the style guide or MT profile; in German this single decision changes verb forms and pronouns across every sentence, not just the greeting.
3. Let inflection be handled automatically — Smartling's Glossary Term Insertion adapts an inserted glossary term's inflection to the sentence's grammatical gender, number, and case, which matters for an n-declension noun like Kunde that changes form in most grammatical positions.
4. Check compliance automatically — a glossary compliance quality check flags any translation that skipped the approved term; how that check runs and how severity is configured is covered in Smartling's guide to glossary compliance checking.
5. Apply the same glossary across every support channel — routing help center, chat, and email content through one translation workflow keeps one termbase in charge; the platform side of that setup is covered in Smartling's guide to customer support content localization.

Este enfoque se adapta a equipos que...

• Publish German-language support content at volume — help center articles, macros, chat, and email — where one inconsistent term multiplies across thousands of strings.
• Run a meaningful share of German content through machine translation or AI translation, where term choice and formality are only as consistent as the rules configured upstream.
• Serve both consumers and business clients in the DACH region, where the right customer term (Kunde vs. Auftraggeber vs. Mandant) changes by audience.
• Have adopted a gender-inclusive language policy ("Kund:innen," "Kundinnen und Kunden") that has to be applied uniformly, not left to each translator's habit.
• Work with multiple linguists or vendors, where an enforced glossary is the only thing keeping everyone's word choices aligned.

What resources are available for learning customer-related vocabulary in German?

Duden, LEO, dict.cc, Linguee, and PONS are the standard references for German customer-related vocabulary, and each has a different strength:

• Duden (duden.de) — the authoritative German dictionary: the place to confirm spelling, gender, and the full declension table of Kunde.
• LEO (dict.leo.org) and dict.cc — German-English dictionaries with active user forums, useful when the question is usage nuance ("Kunde or Klient here?") rather than a definition.
• Linguee — bilingual example sentences drawn from real translated documents, which show how Kunde, Klient, and Auftraggeber behave in context rather than in isolation.
• PONS (pons.com) — a learner-oriented dictionary with grammar tables, better suited than Duden for non-native speakers building vocabulary.
• Goethe-Institut courses — structured German instruction for support agents who need working German for customer conversations, not just a vocabulary list.
• A shared team glossary — for a support organization, the resource that matters most isn't a dictionary but a termbase, because it turns individual vocabulary knowledge into a single enforced standard. Individual learners working alone in one language generally don't need one — a dictionary is enough.

Checklist: questions to answer before standardizing your German customer terminology

Do you address customers as Sie or du?
This is the single highest-impact German language decision a brand makes — it changes verb forms and pronouns in nearly every customer-facing sentence, and switching later means retranslating, not find-and-replace.

Which word is "customer" in your industry?
Kunde is the safe commercial default, but hospitality expects Gast, legal and tax expect Mandant, and advisory services expect Klient — pick per content type and record each in the glossary.

How will you handle gender-inclusive forms?
Decide between the generic masculine (Kunden), paired forms (Kundinnen und Kunden), and typographic forms (Kund:innen) once, because mixing them across a help center reads as carelessness to German readers.

Which terms should never be translated?
Product names and feature names usually stay in English; marking them as do-not-translate (DNT) glossary entries prevents a well-meaning translator from localizing your brand vocabulary.

Can your translation setup actually enforce these decisions?
Confirm the platform supports a formality setting, inflection-aware glossary term insertion, and an automated glossary compliance check — a style guide nobody's tooling reads is documentation, not enforcement.

How does Smartling manage customer terminology in German translation?

Smartling manages German customer terminology through its Terminology Directory, where each glossary entry carries a definition, part of speech, linguistic variations, and Case Sensitive / Exact Match flags — enough structure to recognize "Kunden" as an inflected form of Kunde rather than a separate word. For machine-translated content, Glossary Term Insertion adapts an inserted term's inflection to the surrounding sentence's gender, number, and case instead of dropping in the dictionary form, which is what keeps an n-declension noun like Kunde grammatical in real sentences. Formality is handled as configuration rather than translator preference: the register can be specified in the style guide or MT profile, and AI Formality Adjustment can convert formal German machine translations to the informal register — a feature Smartling supports for German (including regional variants like Austrian German), Italian, and Spanish. Smartling's AI Post-Editing Agent also extracts locale style rules — including tone of voice, formality register, and terminology — from a customer's existing translation memory, so past human decisions about words like Kunde inform future automated output.
