Pre nego što podnese prigovor, potrošač će proveriti očitanje.

Pre nego što is a very common way to say before when it introduces a whole clause, especially in standard Serbian.

• Pre nego što podnese prigovor = before he/she submits a complaint
• It links two actions, so it works like before + subject + verb in English.

You may also hear pre nego in some contexts, but pre nego što is the safest and most standard choice when a verb follows.

Compare:

• Pre podnošenja prigovora... = before the submission of the complaint
  
  • this uses a noun phrase
• Pre nego što podnese prigovor... = before he/she submits a complaint
  
  • this uses a clause with a verb

So in your sentence, pre nego što is completely natural.

Podnese is the present tense form of the perfective verb podneti.

This often confuses English speakers, because in Serbian the present tense of a perfective verb is often used in subordinate clauses to refer to a future completed action, especially after words like:

• kad
• čim
• ako
• pre nego što

So:

• pre nego što podnese prigovor literally looks like before he/she submits a complaint
• but grammatically it is the normal Serbian way to refer to a future action in that clause

Why not podnosi?

• podnositi is imperfective
• podnosi would suggest an ongoing or repeated action, not a single completed act of filing a complaint

Why not podneti?

• podneti is the infinitive
• after što, Serbian needs a finite verb form, not an infinitive

So podnese is exactly what Serbian expects here.

This is an aspect difference.

• podneti = perfective
  focuses on the action as a completed whole
• podnositi = imperfective
  focuses on process, repetition, or ongoing action

In this sentence, the complaint is imagined as one completed act, so the perfective verb is used:

• podnese prigovor = submit/file a complaint

Examples:

• Podneo je prigovor. = He filed a complaint.
• Podnosio je prigovore često. = He used to file complaints often.

Since this sentence talks about a specific future step that happens once, podneti / podnese is the natural choice.

Yes. Će proveriti is the future I form in Serbian.

It is built with:

• the clitic će
• the infinitive or infinitive-based form of the main verb

Here:

• će proveriti = will check

So the main clause is:

• potrošač će proveriti očitanje = the consumer will check the reading

This is the standard way to form the future in Serbian.

Because će is a clitic, and Serbian clitics usually go in the second position of the clause.

In the main clause:

• potrošač će proveriti očitanje

the first element is potrošač, so the clitic će comes right after it.

This is normal Serbian word order.

You could also rearrange the sentence for emphasis, but the clitic still tries to stay in second position within its clause.

For example:

• Potrošač će proveriti očitanje.
• Očitanje će potrošač proveriti.
  This is possible, but marked and less neutral.

So the sentence you have is the neutral, standard order.

Because after conjunctions like pre nego što, Serbian normally does not use će in that subordinate clause when speaking about a future event.

Instead, Serbian commonly uses:

• the present tense of a perfective verb

So:

• pre nego što podnese prigovor = correct
• pre nego što će podneti prigovor = generally not standard in this use

This is one of the places where Serbian works differently from English. English often uses present after before too:

• Before he submits a complaint...

So Serbian is actually doing something fairly similar here, just with its own aspect system.

Prigovor is in the accusative singular here, because it is the direct object of podnese.

The dictionary form is:

• prigovor = complaint, objection

For this masculine noun, the accusative singular is the same as the nominative because it is inanimate:

• nominative: prigovor
• accusative: prigovor

So in:

• podnese prigovor

the form stays prigovor, even though its function is object.

Očitanje is a neuter singular noun.

In this sentence it is the direct object of proveriti, so it is in the accusative singular. For many neuter nouns, nominative and accusative singular have the same form, so:

• nominative: očitanje
• accusative: očitanje

In utility or meter contexts, očitanje often means a reading or meter reading.

So grammatically:

• potrošač = subject
• će proveriti = future verb
• očitanje = direct object

Yes, proveriti is generally perfective.

That means it presents the action as a single completed check:

• proveriti = to check, verify, finish checking

Its imperfective partner is usually:

• proveravati = to be checking, to check repeatedly
• sometimes proveravati / proveriti is the main contrast learners need

In this sentence, the consumer is expected to do one complete action before filing a complaint:

• first check the reading
• then submit the complaint

So the perfective proveriti fits very well.

Sometimes, but not always.

Potrošač most directly means consumer. In legal, administrative, and commercial language, that is often the best translation.

• potrošač = consumer
• kupac = buyer/customer

In everyday speech, English may prefer customer in some contexts, but if the sentence is from rules, regulations, billing, or consumer protection language, consumer is usually the better match.

So for this sentence, potrošač is very likely intentionally formal/legal.

Grammatically, potrošač is singular: the consumer.

But in this kind of formal Serbian, a singular noun often expresses a general rule that applies to any person in that role.

So it can mean something like:

• the consumer will check the reading before submitting a complaint
• meaning any consumer should do this

This is common in legal and instructional style in both Serbian and English.

Yes, but the meaning would shift a bit.

• će proveriti = will check
• treba da proveri = should / is supposed to check

Your original sentence sounds more like a formal procedural statement or rule framed as a future action.
If you used treba da proveri, it would sound more directly like an obligation or recommendation.

So both can appear in official language, but they are not identical.

It has two parts:

1. Pre nego što podnese prigovor
   = subordinate time clause
   = before he/she submits a complaint

2. potrošač će proveriti očitanje
   = main clause
   = the consumer will check the reading

So the pattern is:

• Before X happens, Y will happen

More precisely in Serbian:

• pre nego što + perfective present
• main clause in future

That combination is very common and very natural.
