Le devis est différent de la facture d’artisan.

In French, the usual pattern is être différent de.

So you say:

• différent de
• très différent de
• un peu différent de

This matches English different from more closely than different to or different with.

Examples:

• Ce produit est différent de celui-là.
• Ma version est différente de la tienne.

So in your sentence, Le devis est différent de la facture d’artisan is following the normal French pattern.

Because différent agrees with le devis, not with la facture.

• devis is masculine singular
• so the adjective must also be masculine singular: différent

Compare:

• Le devis est différent.
• La facture est différente.

Even though facture is feminine, it comes after de and is not the subject of the verb est. The subject is Le devis.

French usually uses articles more often than English.

So French naturally says:

• le devis
• la facture

where English might sometimes drop the depending on context.

This is very common in French. In many general statements, French still wants an article where English may not:

• J’aime le café.
• La musique est importante.
• Le devis est prêt.

So Le devis est différent de la facture d’artisan sounds normal in that respect.

Un devis is a price estimate, quote, or cost estimate given before work is done.

It is commonly used for services such as:

• construction
• repairs
• plumbing
• electrical work
• artisan or contractor jobs

A devis is usually given first. A facture comes later, after the work is done or when payment is requested.

So even if the meaning has already been shown, it is useful to know the real-life difference:

• devis = estimate / quote
• facture = invoice / bill

D’artisan is de + artisan, with elision before a vowel.

Here, artisan means a craftsperson or tradesperson, such as a carpenter, plumber, mason, etc.

So la facture d’artisan means something like:

• the artisan invoice
• the invoice from a tradesperson
• the craftsman’s invoice

It describes the kind or source of the invoice.

This is a very useful question, because the meaning changes slightly.

d’artisan

This sounds more general or descriptive. It means something like:

• an artisan invoice
• a tradesperson’s invoice
• the kind of invoice associated with an artisan

de l’artisan

This refers to a specific artisan already known in the situation:

• the invoice from the artisan
• the artisan’s invoice

So:

• la facture d’artisan = more general / descriptive
• la facture de l’artisan = from a particular artisan

In everyday French, if you mean one specific artisan, la facture de l’artisan is often more natural.

It shows elision.

French often drops the vowel of de before a word that begins with a vowel or silent h:

• de + artisan → d’artisan
• de + école → d’école
• de + hôtel → d’hôtel

This is done for smoother pronunciation.

So d’artisan is not a different word; it is just de artisan shortened in the normal French way.

Yes, it is understandable and grammatically fine, but there is one nuance.

Le devis est différent de la facture d’artisan can sound a little general or descriptive because of d’artisan.

If you are talking about one particular artisan, many speakers would more naturally say:

• Le devis est différent de la facture de l’artisan.

If you are speaking more generally about the difference between a quote and an artisan’s invoice as a type of document, the original version works better.

So the sentence is not wrong, but the most natural choice depends on whether you mean:

• a specific artisan
  or
• the general category of artisan invoices

A simple guide:

• Le devis → roughly luh duh-VEE
• est → usually sounds like eh
• différent → roughly dee-feh-RAHN
• de → duh
• la facture → roughly la fak-TUR
• d’artisan → roughly dar-tee-ZAHN

A few helpful points:

• The final s in devis is silent.
• The final t in différent is silent.
• The ending -an in artisan is nasal, so it does not sound like a full English an.

Yes. That is another correct way to express a similar idea.

Compare:

• Le devis est différent de la facture d’artisan.
• Le devis diffère de la facture d’artisan.

The second version uses the verb différer de, which means to differ from.

Both are correct, but:

• est différent de is often more straightforward for learners
• diffère de is a bit more compact and formal in tone

Because French adjective agreement depends on the noun the adjective describes, not just the nearest noun.

In this sentence, différent describes le devis.

Structure:

• Le devis = subject
• est différent = verb + adjective
• de la facture d’artisan = complement after de

So the adjective must match devis, not facture.

This is the same idea as in English:

• The quote is different from the invoice.

The word different describes quote, not invoice.
