Dodavatel dokonce pošle nový účet.

Dodavatel means supplier or provider.

Yes, it is a masculine noun. In this sentence it is the subject, so it appears in the nominative singular form: dodavatel.

A few basic forms are:

• nominative: dodavatel
• accusative: dodavatele
• genitive: dodavatele

So here, Dodavatel = the supplier.

Dokonce usually means even.

In this sentence, it adds a sense of surprise or emphasis:

• Dodavatel pošle nový účet. = The supplier will send a new bill/account.
• Dodavatel dokonce pošle nový účet. = The supplier will even send a new bill/account.

So dokonce suggests that sending a new account/bill is something extra, perhaps more than expected.

Czech often forms the future without a separate word like English will, especially with perfective verbs.

Pošle is the 3rd person singular future form of poslat (to send, perfective).

So:

• pošlu = I will send
• pošleš = you will send
• pošle = he/she/it will send

That is why pošle already means will send.

The infinitive is poslat.

This is a perfective verb, meaning it refers to a completed single action. So poslat / pošle is used when you mean something like:

• send once
• send it off
• get it sent

In contrast, the imperfective verb is posílat, which is more like:

• to be sending
• to send repeatedly
• to send in a general or ongoing sense

This is a very common question.

• pošle = will send as a completed action, usually once
• bude posílat = will be sending / will send repeatedly, focusing on process or repetition

So:

• Dodavatel pošle nový účet. = The supplier will send a new bill/account.
  → one complete act

• Dodavatel bude posílat nové účty. = The supplier will be sending new bills/accounts.
  → ongoing or repeated action

In your sentence, pošle is natural because it sounds like a single future act.

Because účet is the direct object of the verb pošle, it is in the accusative case.

For a masculine inanimate noun like účet, the accusative singular is the same as the nominative singular:

• nominative: nový účet
• accusative: nový účet

That is why the sentence uses nový účet.

By contrast:

• genitive: nového účtu
• dative: novému účtu
• locative: o novém účtu

It can mean several related things depending on context:

• account
• bill
• check (in a restaurant context)
• sometimes invoice-related account statement

In a sentence with dodavatel (supplier), účet most naturally suggests something like a bill or account statement.

However, in business Czech, faktura is often a more precise word for invoice. So depending on the exact context, a learner might also expect:

• Dodavatel pošle novou fakturu. = The supplier will send a new invoice.

So yes, účet is a little context-dependent.

Czech does not use articles like English the and a/an.

So:

• dodavatel can mean a supplier or the supplier
• nový účet can mean a new account/bill or the new account/bill

The exact meaning depends on context.

That is completely normal in Czech. Learners often need to get used to understanding definiteness from the situation rather than from articles.

Yes. Czech word order is fairly flexible, and changing it often changes emphasis, not the core meaning.

Your sentence:

• Dodavatel dokonce pošle nový účet.

Possible alternatives:

• Dokonce dodavatel pošle nový účet.
• Dodavatel pošle dokonce nový účet.

These can all be grammatical, but they highlight different parts of the message.

The given version sounds natural if you are emphasizing the surprising fact that the supplier even will send a new bill/account.

English relies more on fixed word order; Czech uses word order more for information structure and emphasis.

A rough pronunciation guide:

• pošle ≈ POSH-leh
• účet ≈ OO-chet

A few key sounds:

• š = sh as in shoe
• č = ch as in church
• ú is a long oo sound

So the full sentence is roughly:

DO-da-va-tel DO-kon-tseh POSH-leh NO-vee OO-chet

That is only an approximation, but it helps an English speaker get started.

Nový is the adjective new. It has to agree with the noun účet in:

• gender
• number
• case

Since účet is:

• masculine
• singular
• accusative (and masculine inanimate)

the adjective takes the form nový.

Compare:

• nový účet = new account/bill
• nová faktura = new invoice
• nové auto = new car
• nové účty = new accounts/bills

So the ending changes depending on the noun it describes.

Usually yes, especially in business or commercial contexts.

Dodavatel is a standard word for:

• supplier
• vendor
• provider

But exact translation can vary by context. For example:

• a company supplying goods: dodavatel
• a service provider: sometimes poskytovatel
• a seller: sometimes prodejce

In your sentence, dodavatel is perfectly natural for supplier.

In many business contexts, yes.

• Dodavatel dokonce pošle nový účet.
• Dodavatel dokonce pošle novou fakturu.

If you specifically mean an invoice, novou fakturu is often clearer and more idiomatic in modern business Czech.

If the intended meaning is more like account statement, bill, or a more general financial charge, účet may still work.

So a learner should know that účet is possible, but faktura is often the more precise business word.
