Faturalandırma, başvuru numarası verildiği takdirde yeniden incelenecek.

Faturalandırma is a verbal noun meaning billing or invoicing.

It comes from:

• fatura = invoice, bill
• faturalandırmak = to bill, to invoice
• faturalandırma = the act/process of billing

So in this sentence, faturalandırma refers to the billing matter/process rather than a single invoice document.

Depending on context, English translations could be:

• Billing will be reviewed again...
• The invoicing will be re-examined...
• The billing case will be reviewed again...

Başvuru numarası means application number or reference number.

This is a common Turkish noun compound:

• başvuru = application
• numara = number
• başvuru numarası = application number

The second noun takes the possessive ending:

• numara
• numarası = its number / the number of something

So literally, it is something like the number of the application.

This kind of noun compound is extremely common in Turkish:

• telefon numarası = phone number
• kimlik kartı = identity card
• otobüs durağı = bus stop

Verildiği takdirde means if it is given, provided that it is given, or in the event that it is given.

It is a fairly formal expression.

Breakdown:

• verilmek = to be given
• verildiği = that it is/was given
• takdirde = in the case that, if, provided that

Together, verildiği takdirde means something like:

• if it is provided
• provided that it is given
• in case it is submitted

In this sentence, the thing being given is başvuru numarası.

So the sense is: if an application number is provided

Both are possible in many contexts, but they differ in style and tone.

• verilirse = if it is given
• verildiği takdirde = if it is given / provided that it is given

The difference is mainly that verildiği takdirde sounds:

• more formal
• more official
• more bureaucratic
• more typical in written notices, policies, and customer service language

So:

• Başvuru numarası verilirse... = more direct, simpler
• Başvuru numarası verildiği takdirde... = more formal and official

That is why the longer version is very natural in administrative or business Turkish.

Verildiği is built from the passive verb verilmek and a participial structure.

Here is the rough breakdown:

• ver- = give
• veril- = be given
• verildi = it was given
• verildiği = that it is/was given

In this sentence, verildiği is not standing alone as a full main verb. It is part of a subordinate structure linked with takdirde.

You do not need to translate it word-for-word. The easiest way to understand it is:

• başvuru numarası verildiği takdirde = if the application number is given

This kind of -DIK form is very common in Turkish for building subordinate clauses.

İncelenecek means will be examined or will be reviewed.

It comes from:

• incelemek = to examine, review
• incelenmek = to be examined, to be reviewed
• incelenecek = will be examined/reviewed

This is the passive future form.

So the sentence does not say who will do the reviewing. That is very common in Turkish, especially in formal or institutional language.

Compare:

• Yetkililer faturalandırmayı yeniden inceleyecek.
  = The authorities will review the billing again.

• Faturalandırma yeniden incelenecek.
  = The billing will be reviewed again.

The passive makes the sentence sound more impersonal and official.

Yeniden means again or anew.

It usually goes before the verb or verbal element it modifies. Here it modifies incelenecek:

• yeniden incelenecek = will be reviewed again

This placement is very normal in Turkish.

You may also hear tekrar in similar contexts:

• yeniden incelenecek
• tekrar incelenecek

Both can mean will be reviewed again, though yeniden often sounds a bit more formal or neutral.

The comma separates the main topic from the condition.

So the sentence structure is basically:

• Faturalandırma, ... yeniden incelenecek.
• As for the billing, ... it will be reviewed again.

The middle part gives the condition:

• başvuru numarası verildiği takdirde = if the application number is provided

In English, you might or might not use commas depending on style, but in Turkish official writing, this kind of comma is common and helps readability.

Turkish often leaves out bir when English would naturally use a or an.

So:

• başvuru numarası can mean an application number or the application number, depending on context

Turkish does not use articles the same way English does. The sentence is understood generically:

• if an application number is provided

Adding bir would put more emphasis on the existence of one:

• bir başvuru numarası = a certain application number / some application number

But here, leaving it out sounds more natural and official.

The main verb incelenecek is clearly future:

• will be reviewed
• is going to be reviewed

So the main clause is future.

The condition verildiği takdirde does not need a future marker in Turkish. Turkish often uses a non-future-looking form inside conditional or subordinate clauses where English still translates it as future-related.

So the full meaning is:

• Billing will be reviewed again if the application number is provided.

That is normal Turkish grammar: the future meaning is carried by the main verb.

Yes, it is natural, especially in formal or administrative contexts.

It sounds like something you might see in:

• customer service messages
• email responses
• finance or billing departments
• official notices
• support tickets
• institutional correspondence

The tone is:

• formal
• neutral
• impersonal
• professional

A less formal everyday version might be something like:

• Başvuru numarasını verirseniz, faturalandırmayı tekrar inceleyeceğiz.
  = If you give the application number, we will review the billing again.

The original sentence is more official because it uses:

• the passive
• the formal conditional structure verildiği takdirde
• an impersonal style
