Заявление о страховой выплате готово, а франшиза уже указана.

Because заявление is a neuter singular noun.

The short-form adjective готов agrees with the noun:

• готов — masculine
• готова — feminine
• готово — neuter
• готовы — plural

So:

• заявление готово = the application/statement is ready

If the noun were different, the form would change:

• документ готов
• форма готова
• документы готовы

Because the preposition о normally takes the prepositional case.

Here:

• страховая выплата = insurance payout / insurance payment
• after о, it becomes о страховой выплате

So the phrase literally means about the insurance payout or regarding the insurance payout.

This is very common with заявление:

• заявление о приёме на работу = an application for employment
• заявление о потере паспорта = a statement about the loss of a passport
• заявление о страховой выплате = a claim/application regarding an insurance payout

Заявление is a broad word that can mean things like:

• statement
• application
• formal request
• claim

In an insurance context, заявление о страховой выплате is usually a claim/application for an insurance payout.

So even though the core meaning of заявление is broad, the surrounding words make the insurance meaning clear.

Not here.

In insurance, Russian франшиза usually means deductible or excess — the amount the insured person must cover before the insurer pays.

So this is a false friend for English speakers:

• франшиза can mean franchise in business/media contexts,
• but in insurance it often means deductible.

You have to understand it from context. Since the sentence is about an insurance payout, the insurance meaning is intended.

Because франшиза is a feminine singular noun, and указана agrees with it.

This form comes from указать = to indicate / specify.

Short passive participle forms are:

• указан — masculine
• указана — feminine
• указано — neuter
• указаны — plural

So:

• франшиза указана = the deductible is specified / has been indicated

This is a very common Russian way to express a resulting state:

• адрес указан
• дата указана
• сумма указана

It is a short passive participle, so it is a verb-derived form used as part of the predicate.

In practice, learners often understand it like:

• is indicated
• is specified
• has been indicated

It behaves a bit like an adjective because it agrees with the noun, but it comes from a verb and keeps a passive meaning.

So in this sentence:

• франшиза уже указана = the deductible has already been specified

Because Russian usually omits the verb "to be" in the present tense.

So:

• Заявление ... готово literally looks like Application ... ready
• франшиза уже указана literally looks like deductible already specified

But in natural English we translate them as:

• The application is ready
• The deductible has already been specified

Russian does use forms of быть in the past and future, but normally not in the present:

• Заявление было готово = The application was ready
• Заявление будет готово = The application will be ready

А often links two clauses while showing a contrast, comparison, or shift of topic.

Here it is not a strong contradiction like but, but more like:

• and meanwhile
• whereas
• and as for
• sometimes simply and

So:

• Заявление ... готово, а франшиза уже указана.

suggests something like:

• The claim form is ready, and the deductible is already specified.

Using а makes the second clause feel like a parallel piece of information, with a slight contrast or separation between the two facts.

If you used и, it would feel more like simple addition:

• ... готово, и франшиза уже указана

That is possible in some contexts, but а sounds very natural here.

Уже means already.

Here it emphasizes that the deductible has been specified by this point:

• франшиза уже указана = the deductible has already been specified

It often adds a sense that something is completed sooner than expected, or that the speaker is pointing out an existing result.

Compare:

• франшиза указана = the deductible is specified
• франшиза уже указана = the deductible is already specified

Russian word order is fairly flexible, but changing it changes the focus or emphasis.

The given sentence is neutral and natural:

• Заявление о страховой выплате готово, а франшиза уже указана.

Other orders are possible, for example:

• Франшиза уже указана, а заявление о страховой выплате готово.
• Заявление о страховой выплате готово, а уже указана франшиза.
  This is possible, but less neutral and more stylistically marked.

So yes, Russian allows movement, but the original version is a good standard order for straightforward written information.

Because а connects two separate clauses, each with its own predicate:

• Заявление ... готово
• франшиза ... указана

In Russian, a comma is normally used before coordinating conjunctions like а when they join independent clauses.

So the comma here is standard punctuation, not optional.
