Il committente chiede di fatturare l'acconto.

Committente is a fairly formal/business word. It usually means the client, the customer who commissioned the work, or the contracting party.

It is not the most casual everyday word for customer. In a business, legal, freelance, construction, or invoicing context, committente is very common because it refers specifically to the person or company that has ordered or commissioned something.

So in this sentence, il committente is the person/company asking for the deposit to be invoiced.

In Italian, articles are used more often than in English. Il committente literally means the client.

Even where English might sometimes say just client in note-style or headline-style language, Italian normally keeps the article:

• Il cliente
• Il committente
• Il fornitore

So il here is completely normal and not optional in standard sentence structure.

Because in Italian, when chiedere means to ask/request someone to do something, it is commonly followed by di + infinitive.

So the pattern is:

• chiedere di + infinitive

Examples:

• Chiede di pagare subito. = He/She asks to pay immediately.
• Chiedono di inviare il documento. = They ask to send the document.
• Il committente chiede di fatturare l'acconto.

Using chiede fatturare without di would be ungrammatical.

It is in the infinitive because it depends on chiede di.

This is a very common structure in Italian:

• chiedere di fare qualcosa
• decidere di fare qualcosa
• cercare di fare qualcosa

So:

• chiede = asks
• di fatturare = to invoice / to issue an invoice for

The infinitive is used because the sentence expresses the action being requested, not a fully conjugated second verb.

The sentence does not explicitly say it, but the implied meaning is:

The client is asking someone else to invoice the deposit.

In real life, that usually means the client is asking the supplier, freelancer, accountant, or company handling the paperwork to issue the invoice.

So grammatically:

• Il committente = the one making the request
• chiede di fatturare l'acconto = asks that the deposit be invoiced

The person who actually does fatturare is understood from context, not directly stated.

Fatturare means to invoice or to issue an invoice for something.

It comes from fattura = invoice.

So:

• fatturare un servizio = to invoice a service
• fatturare un importo = to invoice an amount
• fatturare l'acconto = to invoice the deposit/down payment

In business Italian, this is a very common verb.

Acconto means deposit, advance payment, or down payment.

It refers to money paid before the full amount is paid.

Common related terms:

• acconto = deposit / advance
• saldo = balance / remaining amount

For example:

• Pagare un acconto = to pay a deposit
• Versare un acconto = to make an advance payment
• Fatturare l'acconto = to invoice the deposit

Because acconto begins with a vowel, and il contracts to l' before many singular masculine nouns starting with a vowel.

So:

• il libro
• il cliente
• but l'acconto
• l'importo

This is the same kind of contraction you see in:

• l'uomo
• l'ordine
• l'ufficio

So l'acconto simply means the deposit.

Not in the same simple structure.

With chiedere, Italian often uses:

1. chiedere di + infinitive

   • Il committente chiede di fatturare l'acconto.

2. chiedere che + subjunctive

   • Il committente chiede che venga fatturato l'acconto.
   • Literally: The client asks that the deposit be invoiced.

Both are possible, but di + infinitive is simpler and often more direct. The che + subjunctive version sounds a bit more formal or explicit.

Yes, it sounds fairly formal and business-like.

Words such as:

• committente
• fatturare
• acconto

all belong naturally to administrative, commercial, legal, or accounting language.

In more everyday speech, people might choose simpler wording depending on context, but in professional communication this sentence sounds very natural.

Yes, some variation is possible, but the original order is very natural.

Standard order:

• Il committente chiede di fatturare l'acconto.

You could also find more explicit alternatives, such as:

• Il committente chiede la fatturazione dell'acconto.
• Il committente chiede che l'acconto venga fatturato.

But you cannot move things around freely in a way that breaks the structure. For example, chiede di must stay together as a unit introducing the infinitive clause.

So the original sentence is a normal, correct way to say it.

Either can work, depending on tone.

• asks is the most direct literal translation
• requests often fits better in business English

That is because chiedere covers both ideas in Italian. In formal or professional contexts, English often prefers request where Italian still simply uses chiedere.

So in this sentence, both of these are reasonable:

• The client asks to invoice the deposit.
• The client requests that the deposit be invoiced.

The second usually sounds more natural in polished business English.
