Facciamo un'offerta oggi.

Because Italian usually drops subject pronouns when the verb already makes the subject clear.

• Facciamo already means we do / we make
• So noi is not necessary

You could say Noi facciamo un'offerta oggi, but that usually adds emphasis, contrast, or clarity, such as:

• Noi facciamo un'offerta oggi, loro domani = We are making an offer today, they tomorrow.

Facciamo is the 1st person plural form of fare, meaning to do or to make.

Here it corresponds to we make or we are making, depending on context.

So:

• fare = to do / to make
• facciamo = we do / we make / we are doing / we are making

Italian simple present often covers both the English simple present and present continuous.

Yes. This is a very common point of confusion.

Facciamo can mean either:

• we make / we are making
• let's make

The form is the same for the present indicative and the 1st person plural imperative.

So Facciamo un'offerta oggi could mean:

• We’re making an offer today
• Let’s make an offer today

Context, tone of voice, or punctuation usually makes the meaning clear.

Because offerta is a feminine singular noun that begins with a vowel.

Before a feminine singular noun beginning with a vowel, una becomes un'.

So:

• una casa
• un'offerta

The apostrophe shows that the final -a of una has been dropped.

This only happens with the feminine article:

• un'offerta = feminine
• un uomo = masculine, with no apostrophe

Because fare un'offerta is the normal Italian expression for to make an offer.

This works very much like English:

• make an offer
• fare un'offerta

You can also use offrire, but that usually means to offer something directly:

• Offriamo 200 euro = We offer 200 euros
• Facciamo un'offerta = We make an offer

So fare un'offerta focuses on the act of submitting or making an offer.

Yes, it can move.

In this sentence, oggi at the end sounds completely natural:

• Facciamo un'offerta oggi

But Italian is more flexible than English with word order, so you could also say:

• Oggi facciamo un'offerta
• Facciamo oggi un'offerta (possible, but often less natural in everyday speech)

The most common choices are usually:

• Oggi facciamo un'offerta
• Facciamo un'offerta oggi

The position can slightly change the emphasis:

• Oggi first = stronger focus on today
• oggi at the end = more neutral flow

It can do both.

Italian often uses the present tense for actions happening:

• now
• today
• in the near future
• according to a plan or decision

So Facciamo un'offerta oggi can naturally mean something like:

• We’re making an offer today
• We make an offer today
• We’ll make an offer today

English often prefers a future form in some contexts, but Italian is very comfortable using the present for planned actions.

Offerta is feminine singular.

A useful clue is the ending -a, which is very often feminine in Italian.

That is why it takes:

• un' in the singular before a vowel
• l'offerta for the offer

Examples:

• un'offerta
• l'offerta
• due offerte

The plural is offerte.

A simple English-friendly guide would be:

fah-CHAH-mo oon-of-FEHR-tah OHJ-jee

A few useful pronunciation notes:

• ci in facciamo sounds like ch in church
• ccia makes a stronger ch sound than a single c
• gg in oggi sounds like the j in jam, but held a little more firmly
• stress falls on:
  • facCIAmo
  • ofFERta
  • OGgi

So the natural stress pattern is:

fac-CIA-mo un-of-FER-ta OG-gi
