Guide
Issue an invoice in 30 seconds.
A step-by-step guide — mandatory fields, the VAT rules and tips to make the job easier.
How it works
Three steps to a finished invoice.
In eFaktúra you issue an invoice in under a minute. From picking the customer to the QR payment — no needless retyping, no spreadsheet templates.
- 1
Enter the customer's Company ID (IČO) or name
Just type the Company ID (IČO) or the name — the system automatically fills in the business name, address, Tax ID (DIČ) and VAT ID (IČ DPH) from eFirma and the Commercial Register (ORSR). A customer without a Company ID (an individual, a landlord or a foreign company) can be added manually in seconds.
What the system fills in- Business name
- Registered office
- Tax ID / VAT ID
- 2
Add the line items and amounts
Add a description of the goods or service, the quantity and the unit price. The system calculates the VAT, the taxable amount and the total.
Automatically- VAT calculation
- Item templates
- Recurring invoices
- 3
Send it and keep track
Send the invoice by e-mail straight from the system. A PDF is generated with a PAY by square QR code for instant payment.
After sending- Open tracking
- Due-date reminders
- Payment matching
Mandatory fields
What an invoice must contain.
Based on § 74 of the VAT Act, Act No. 222/2004 Coll. (zákon č. 222/2004 Z. z. o DPH), and § 3a of the Commercial Code (Obchodný zákonník). The Company ID (IČO) is shown only where one has been assigned — you can still issue an invoice when you or your customer have no IČO (a landlord registered with the tax office only, for example). eFaktúra checks the details before sending so that nothing important is missing from the invoice.

Common mistakes
What to avoid.
Six mistakes that cause the biggest problems during a tax inspection. eFaktúra checks for every one of them before an invoice is sent and warns you before you sign it off.
1A missing VAT ID (IČ DPH) on an invoice from a VAT payer
2A wrong or missing date of supply
3The wrong VAT rate (20% vs 10% vs 0%)
4A missing sequential invoice number
5An incorrectly formatted bank account number
6A non-VAT payer missing the wording ‘Nie som platiteľ DPH’
eFaktúra checks all six for you. The system warns you before sending and never lets you sign off an invalid invoice.
