La cotización incluye la reparación.

Yes. In this context, cotización usually means a price quote, estimate, or cost proposal.

In much of Latin America, cotización is common in business, services, repairs, and sales. It refers to the amount or document showing how much something will cost.

Depending on the country and situation, you may also hear:

• presupuesto = estimate / budget
• cotización = quote / estimate
• precio = price

So La cotización incluye la reparación means that the quoted price already covers the repair.

Spanish often uses definite articles more frequently than English.

Here:

• la cotización = the quote / the estimate
• la reparación = the repair

Even if English might sometimes say Repair included in quote, Spanish normally sounds more natural with the articles:

• La cotización incluye la reparación.

Both nouns are feminine singular, so they take la.

Both nouns end in -ción, and nouns ending in -ción are almost always feminine.

So:

• la cotización
• la reparación

This is a very useful pattern in Spanish. Other examples:

• la información
• la solución
• la conversación

Their plural forms are:

• las cotizaciones
• las reparaciones

Incluir is the infinitive, meaning to include.

In the sentence, the verb is conjugated to match the subject la cotización, which is third person singular:

• incluir = to include
• incluye = it includes

So the structure is:

• La cotización = the subject
• incluye = the verb
• la reparación = the object

Literally: The quote includes the repair.

Because la reparación is a thing, not a person.

In Spanish, the personal a is generally used before a specific person or sometimes a pet or personified being. But it is not used before ordinary things.

So:

• incluye la reparación = correct
• incluye a la reparación = incorrect

Compare:

• Veo el carro = I see the car
• Veo a María = I see María

Usually, yes, but the nuance depends on context.

Reparación is the repair itself, or the act/service of repairing something.

Examples:

• La reparación cuesta mucho. = The repair costs a lot.
• Incluye la reparación. = It includes the repair.
• Necesita reparación. = It needs repair.

If you want the verb to repair, that is reparar:

• reparar = to repair
• la reparación = the repair

Yes, absolutely. In many contexts, presupuesto may sound even more natural, depending on the country and situation.

A rough distinction is:

• cotización = quote, often more formal or business-related
• presupuesto = estimate/budget, very common for services and repairs

In real life, both can work. Which one is preferred can vary by region and industry.

In most of Latin America, it is pronounced approximately like:

ko-tee-sa-SYON

A few useful notes:

• coti- sounds like ko-tee-
• the z in most of Latin America sounds like s
• the final -ción is stressed on -ón

So:

• cotización → stress on the last syllable
• reparación → also stress on the last syllable

That written accent mark helps show the stress.

They have written accents because they are words ending in -n and stressed on the last syllable.

Normally, if a Spanish word ends in a vowel, n, or s, the stress falls on the second-to-last syllable unless there is a written accent.

But these words are stressed at the end:

• coti-za-ción
• repa-ra-ción

So they need the accent mark to show that pronunciation.

Yes. If you are talking about more than one quote or more than one repair, you change the nouns, articles, and sometimes the verb.

Examples:

• Las cotizaciones incluyen la reparación.
  = The quotes include the repair.

• La cotización incluye las reparaciones.
  = The quote includes the repairs.

• Las cotizaciones incluyen las reparaciones.
  = The quotes include the repairs.

Notice:

• la → las
• cotización → cotizaciones
• reparación → reparaciones
• incluye → incluyen when the subject is plural

Yes. It sounds natural, especially in customer service, repair shops, invoices, service proposals, and business communication.

You might see or hear similar sentences such as:

• La cotización incluye mano de obra. = The quote includes labor.
• La cotización no incluye refacciones. = The quote does not include parts.
• El presupuesto incluye la instalación. = The estimate includes installation.

So this is a very practical sentence for real-world Latin American Spanish.

Not in that form. That sentence is not natural Spanish.

If you want to express the same idea, use one of these:

• La cotización incluye la reparación.
• La reparación está incluida en la cotización.

The first means:

• The quote includes the repair.

The second means:

• The repair is included in the quote.

So if you use está incluida, you also need en la cotización.

Here are some very common related words in Latin American service and repair contexts:

• mano de obra = labor
• refacciones / repuestos = replacement parts / spare parts
• garantía = warranty
• diagnóstico = diagnosis / inspection
• instalación = installation
• mantenimiento = maintenance
• costo = cost
• precio = price
• anticipo = deposit / advance payment

Examples:

• La cotización incluye mano de obra y refacciones.
• La garantía no incluye daños por mal uso.
• El diagnóstico está incluido en el precio.

These are very useful if you are dealing with mechanics, appliance repair, home services, or technical support.
