Practical guide

Activating eInvoice step by step

Everything starts right in BizNow. You choose the scope of the service: for sending only you complete an online verification (KYC), for sending and receiving the registration goes through the Financial Administration without KYC verification.

  • No separate paper contracts
  • Online activation
  • Included in your plan at no extra charge
01

Open the company settings

Log in to BizNow. Go to Settings (Nastavenia) → My companies (Moje firmy), find the company for which you want to activate eInvoice and click the orange pencil icon (Edit) in the Action column on the right.

Settings → My companies → pencil in the Action column
02

Choose the eInvoice scope

In the Edit company details window find the eInvoice panel (e‑Faktúra). You will see the options send only, send and receive, or registration through an authorized person.

Activation options in the company detail

Which option should you choose?

Choose one of three procedures depending on whether you want to only send eInvoices, send and receive them, or have another authorized person handle the registration.

Mode: sending only

Suitable if you want to create and send eInvoices in BizNow but you already have receiving covered by another digital postman.

  1. Click "Activate sending of eInvoices" (Aktivovať odosielanie e-faktúr).
  2. Complete the KYC verification through Dativery using the procedure below. The contact person, the company identity, its authority to act and the bank account are verified.
  3. After the verification and service activation are successfully completed, you can send eInvoices through BizNow.

Important: This mode does not cover receiving. If your company is obliged to receive eInvoices, it must arrange receiving separately.

Mode: sending and receiving

Suitable if you want a digital postman and two-way exchange of eInvoices right in BizNow.

  1. Click "Activate sending and receiving of eInvoices" (Aktivovať odosielanie a prijímanie e-faktúr). This option does not require KYC verification.
  2. Then go to the Financial Administration portal for choosing a digital postman. Log in and allow the application the access it needs.
  3. Choose the right taxable entity (your company), check the details and fill in the required email and phone number.
  4. Choose CyWo Tech, a. s. (BizNow) as the intermediary. The technical provider of the delivery service is Dativery s.r.o.
  5. Confirm the sharing of data with the Allow button, continue with the submission and wait for the Submission confirmation to appear.
  6. Return to BizNow and check the activation status. Until the activation is confirmed, do not assume that receiving is active.

Note: After registration, an automatic synchronization takes place between the Financial Administration and the Peppol network, which can take up to 60 minutes. No further steps are needed on your side.

Sending and receiving, through an authorized person

If another authorized person (for example your accountant) arranges the BizNow registration with the Financial Administration on behalf of your company, you do not have to do this step yourself. BizNow sends them a request by email.

  1. In Settings → My companies → Edit click the third option "Activate sending and receiving of eInvoices – registration through an authorized person" (Aktivovať odosielanie a prijímanie e-faktúr – registrácia prostredníctvom poverenej osoby).
  2. BizNow sends the authorized person an email request to complete the BizNow registration with the Financial Administration on behalf of your company.
  3. On the Financial Administration portal the authorized person completes the BizNow registration, that is, chooses CyWo Tech, a. s. (BizNow) as the eInvoice intermediary for the given taxable entity.
  4. After the registration is complete, check the status of eInvoice sending and receiving activation in BizNow.

Note: After registration, an automatic synchronization takes place between the Financial Administration and the Peppol network, which can take up to 60 minutes. No further steps are needed on your side.

Identity verification (KYC)

03 Client verification through Dativery (Peppoš), for sending only

If you chose sending eInvoices only, BizNow takes you to a secure KYC verification, which is technically performed by Dativery s.r.o. through the Peppoš service. Its goal is to verify the company, the contact person and the authority to act on behalf of the company.

  • Contact personFill in the first name, last name, role in the company, email and mobile number of the person carrying out the verification.
  • EmailConfirm the email address following the instructions in the verification message you receive.
  • PhoneVerify the mobile number you entered using the verification method offered.
  • Company identityDativery checks the company's identification data and its relationship to the contact person. Depending on the chosen method, it may require further confirmation of identity or of the authority to represent the company.
  • Bank account: €1 verification transferFrom the bank account of the company being verified, send €1 using the payment details Peppoš shows you (including a unique variable symbol). Dativery uses the payment received to verify that the bank account belongs to the company. Payment verification usually takes up to 2 minutes, but in some cases it can take several hours. You do not have to wait on the page: after sending the payment you can close it. After successful verification you will receive an email confirming that the payment was received and the verification was successful.

Important: The bank transfer helps verify the company account, but on its own it is not the only proof of authority to act on behalf of the company. Dativery also assesses the identity and authority of the person. Always take the payment details directly from the secure wizard; the €1 is a verification transfer, not a monthly fee for eInvoice in BizNow.

A preview of the Peppoš KYC wizard: contact details, email and phone verification, company identity and bank account.

Price: The eInvoice function is free in every plan. An eInvoice is an invoice, so it counts towards the fixed number of documents in your plan.

How to send your first eInvoice

After activation, eInvoice statuses appear next to issued invoices. Creating the invoice is not enough: first verify it and then send it through Peppol.

01

Find the issued invoice

Go to Documents → Approved revenue → Invoices (Dokumenty → Schválené výnosy → Faktúry). In the eInvoice column you will see the document status. Open the invoice with the eye or pencil icon.

02

Verify the invoice

In the Edit document window you will find the Verify invoice button (Overiť faktúru) at the bottom left. We recommend using it first to check that Peppol will accept the invoice as issued. If the data is correct, you will see the message "The invoice is valid – Peppol will accept it." Verification does not send the invoice yet. Only then click Send eInvoice (Poslať eFaktúru). You can later display the status and delivery confirmations from Peppol at any time by clicking the eInvoice icon right in the table.

03

Send through Peppol

Click Send eInvoice and wait for the result (it can take up to about 2 minutes). A successful submission is marked by a green "e". If there is an error, click the status and read the Peppol log.

How to read eInvoice statuses

Each icon shows the current status. If you need details, click the icon in the invoice list.

Not sent

The invoice has not been sent through Peppol yet.

Warning

The invoice was not sent on the day it was issued. Send it as soon as possible.

Sent successfully

The invoice was sent. You can find the available confirmations in the Peppol log.

Error

Sending or delivery failed. Click the icon to see the reason.

Peppol log detail

Click the eInvoice status icon right in the table to open the Peppol log. You will see the time of sending and delivery, technical confirmations (e.g. AS4 or MLR), any reply from the customer and information about reporting to the Financial Administration, if available.

An example of the Peppol log shown after clicking the icon.

Warning: An eInvoice that has already been sent cannot simply be edited or sent again. Use the appropriate corrective document to fix it. If the customer is not registered in the Peppol network, BizNow will warn you. As an alternative, you can use the "Resend" button (Preposlať) at the bottom right of the invoice detail. The customer is sent an email with the invoice attached as both PDF and XML (Peppol BIS Billing 3.0). The PDF is for reading, while the structured XML is the eInvoice format used for mandatory electronic invoicing from 1 Jan 2027.

Important: If the law requires delivery through Peppol, an email alone does not replace that way of delivery.

Received eInvoices

Where to find received eInvoices

BizNow automatically checks for new eInvoices received through Peppol every 10 minutes. You will find them in Documents → Documents to approve (Dokumenty → Dokumenty na schválenie). They are marked with an "e" next to the document type, so you can recognize them easily. From there you can approve them and process them further like other documents.

When does an invoice appear? Although BizNow checks for new eInvoices every 10 minutes, the time it takes them to be delivered through the Peppol network can vary depending on processing in the individual systems involved. In exceptional cases an invoice may therefore appear in BizNow only a few hours after the supplier sent it. Once it is available at the digital postman, BizNow picks it up at the next regular check.

Documents to approve: received invoices are marked with an "e" next to the document type.

The procedure is based on the BizNow interface, on information materials from the Financial Administration and on the verification principles of the Peppol network. KYC details may vary depending on the chosen method. Official Financial Administration information ↗

Who is affected by the obligation from 1 Jan 2027?

According to the Financial Administration, the scope of the obligations is not the same for everyone. In simple terms:

StatusIssuing and sendingReceiving
VAT payerYes, for domestic B2B/B2G supplies specified by lawYes
VAT non-payerNo, not obliged to issueYes, when the obligation applies to them

Mandatory eInvoicing does not apply to invoicing ordinary consumers (B2C).

The exact scope of the obligations depends on the status of the entity and the specific transaction. Always check the current rules in the Financial Administration materials.

The most common questions

Is an eInvoice just a PDF?

No. An eInvoice is a structured electronic document in XML format following European standards. A PDF can only be its readable representation. Thanks to the structure, the system can process it automatically, with no manual retyping.

Do I need a separate digital postman outside BizNow?

No. If you choose BizNow/CyWo Tech as the intermediary of the delivery service, you can handle eInvoices through BizNow with no additional separate user environment. You keep received and sent eInvoices together with your other company documents.

What is Peppol?

Peppol is a European network and standard for the secure, interoperable exchange of structured electronic documents, including invoices. BizNow sends and receives eInvoices through it. You do not need to install or set up anything else.
