الايصال فيه التكلفة وقطعة الغيار.

It is basically both.

Literally, فيه means in it. But in Egyptian Arabic, this structure is very commonly used to mean that something contains, has, or includes something.

So الايصال فيه التكلفة وقطعة الغيار is literally something like:

The receipt — in it are the cost and the spare part.

In natural English, that becomes:

The receipt has/includes the cost and the spare part.

Because Arabic often does not need a verb like English has in the present tense.

In Egyptian Arabic, one common way to express X has Y for things, documents, containers, lists, etc. is:

X + فيه + Y

So here:

الايصال فيه...
= the receipt has... / the receipt includes...

For people, Egyptian often uses عنده / عندها for has, but for something being physically or textually inside/on another thing, فيه is very natural.

Because الايصال is the topic of the sentence.

Arabic often uses a topic-comment structure. The speaker first names what they are talking about, then says something about it:

الايصال → the receipt
فيه التكلفة وقطعة الغيار → it has the cost and the spare part

So the feel is a bit like:

As for the receipt, it has the cost and the spare part on it.

Starting with الايصال makes the document the main focus.

Because فيه refers back to الايصال (the receipt), not to التكلفة وقطعة الغيار.

The word إيصال is singular masculine, so فيه matches that idea: in it.

The two nouns after it are simply the things contained in the receipt; they do not change the form of فيه.

التكلفة means the cost, the charge, or the expense.

In the context of a receipt, it usually means the amount being charged or the listed cost of the work/item.

Because it has الـ, it means the cost as a specific, identifiable item, not just a cost in a general sense.

Yes. قطعة غيار / قطعة الغيار is a very common expression meaning a spare part / the spare part.

Literally, it is something like a replacement piece/part.

This is an everyday phrase in Egyptian Arabic, especially in contexts like cars, appliances, and repairs.

A very common plural expression is:

قطع غيار = spare parts

Because قطعة ends with ـة (taa marbuuTa).

When a word ending in ـة is said by itself, that ending is often not heard as a full t in pause. But when the word is connected to another noun in a linked phrase, the t sound comes back.

So:

قطعة by itself
but
قطعة الغيار with a clear t link

That is why learners often hear something closer to ...-tet el-ghiyaar than just ...-ta.

Because ت is a sun letter.

In Arabic, when الـ comes before a sun letter, the l sound is absorbed into the next consonant. So:

التكلفة is pronounced roughly et-taklifa

not el-taklifa.

By contrast, in الايصال, you keep the el- sound, because there is no sun-letter assimilation there.

Because the speaker is referring to specific, known items:

• الايصال = the receipt
• التكلفة = the cost
• قطعة الغيار = the spare part

This makes sense in a real-life situation where both speaker and listener know which receipt, which cost, and which part are being discussed.

Also, in قطعة الغيار, the whole phrase is definite because the second noun, الغيار, is definite.

Yes, إيصال is a normal word for receipt, especially as proof of payment.

A related word you may also hear is فاتورة, which usually means bill or invoice. In everyday speech, people may sometimes use them loosely, but they are not exactly the same thing.

So in this sentence, الايصال is a very natural choice if the document is a receipt.

Because in Egyptian Arabic, the conjunction و is commonly pronounced we, not wa as in careful Standard Arabic.

So a speaker would typically say something like:

... et-taklifa we ...

This is completely normal in Egyptian speech and is one of the first pronunciation differences learners notice.
