ग्राहक सेवा यहाँ है।

A natural pronunciation is roughly:

grāhak sevā yahā̃ hai

A more detailed breakdown:

• ग्राहक = grā-hak
  • ग्रा sounds like graa
  • हक sounds like hak
• सेवा = se-vā
  • से like say
  • वा like vaa
• यहाँ = yahā̃
  • the final vowel is nasalized, so it sounds like yahaan with a nasal tone
• है = hai
  • like hai in high, but shorter and lighter in normal speech

A smooth reading would be:

grāhak sevā yahā̃ hai

The sentence breaks down like this:

• ग्राहक = customer
• सेवा = service
• यहाँ = here
• है = is

So ग्राहक सेवा literally means customer service, and the full sentence means Customer service is here.

Hindi often places information in a different order from English. In this sentence:

• ग्राहक सेवा = the thing being talked about
• यहाँ = location
• है = is

So the structure is basically:

[subject] + [location] + [is]

That is very normal in Hindi. A literal English-style gloss would be:

Customer service here is.

But in natural English, we say:

Customer service is here.

Because Hindi usually puts the main verb at the end of the sentence. This is one of the most important sentence-pattern differences between Hindi and English.

So:

• English: Customer service is here
• Hindi: ग्राहक सेवा यहाँ है

This verb-final pattern is extremely common in Hindi.

है is used for a singular subject, and हैं is used for plural or for respectful you.

Here, ग्राहक सेवा is treated as a single thing: customer service. So है is correct.

Examples:

• ग्राहक सेवा यहाँ है। = Customer service is here.
• ग्राहक सेवाएँ यहाँ हैं। = Customer services are here. / Customer service departments are here.

So the sentence uses है because the subject is singular.

Yes, सेवा is a feminine noun, and the compound ग्राहक सेवा is generally treated as feminine because the head noun is सेवा.

In this particular sentence, you do not see a gender change in the verb, because in the present tense with है, the form stays the same.

But gender can show up elsewhere. For example:

• अच्छी ग्राहक सेवा = good customer service

Here अच्छी is feminine, matching सेवा.

So even though ग्राहक itself means customer, the whole expression is centered on service, which is feminine.

It is understandable and grammatically fine, but whether it sounds fully natural depends on the situation.

If you want to say Customer service is here in a straightforward way, ग्राहक सेवा यहाँ है works.

But in real-life contexts, native speakers might also say things like:

• ग्राहक सेवा यहाँ उपलब्ध है। = Customer service is available here.
• ग्राहक सेवा काउंटर यहाँ है। = The customer service counter is here.
• यहाँ ग्राहक सेवा मिलती है। = Customer service is available here.

So your sentence is correct, but other versions may sound more natural depending on whether you mean:

• the department is located here
• help is available here
• the counter/desk is here

Yes, very often.

On signs, notices, labels, maps, and headings, Hindi frequently drops the verb if the meaning is still clear.

So you might see:

• ग्राहक सेवा यहाँ
• ग्राहक सेवा काउंटर
• ग्राहक सेवा विभाग

This is similar to English signs that say:

• Customer Service
• Customer Service Here

rather than full sentences.

So:

• ग्राहक सेवा यहाँ है। = full sentence
• ग्राहक सेवा यहाँ = very sign-like, concise version

Both can work, depending on context.

These words are related but not identical.

• यहाँ = here
  • the normal, neutral word
• यहीं = right here / exactly here
  • adds emphasis
• इधर = this side / over here
  • often a little more directional or conversational

Examples:

• ग्राहक सेवा यहाँ है। = Customer service is here.
• ग्राहक सेवा यहीं है। = Customer service is right here.
• ग्राहक सेवा इधर है। = Customer service is over here.

For your sentence, यहाँ is the most neutral and standard choice.

Hindi does not use articles the way English does. There is no direct equivalent of a/an/the in most ordinary sentences.

So ग्राहक सेवा यहाँ है can mean:

• Customer service is here
• The customer service desk is here
  depending on context

Hindi often leaves that kind of specificity to the situation rather than marking it with an article.

This is very normal, and English speakers need some time to get used to it.

It is a noun + noun combination where the first noun modifies the second.

• ग्राहक = customer
• सेवा = service

So together:

ग्राहक सेवा = service for customers = customer service

This is a very common pattern in Hindi. Similar examples:

• विद्यालय भवन = school building
• बस स्टैंड = bus stand
• पुस्तक मेला = book fair

So ग्राहक सेवा is not unusual at all; it is a normal way to form a compound noun in Hindi.
