Where to find company settings
Edit your company details in Settings → Company details. This is where you'll find everything that gets printed on your invoices — filling it in correctly is essential for your invoices to be legally valid and meet the requirements of the VAT Act and the Accounting Act. The same tab also carries your tax settings (VAT status, tax period, flat-rate expenses, insurance and tax office); those are covered in the Tax settings article.
What you can edit in company settings
The page is split into several sections:
Basic details
- Company name — exactly as registered in the Trade Licensing Register or the Commercial Register.
- Company ID (IČO) — an eight-digit identification number.
- Self-employment start date — used for prorated insurance calculations in your first year of business.
- Primary business activity (CZ-NACE) — chosen from the Financial Administration's full code list; you can search by code or name. It is stated on a VAT payer's VAT return and on the income tax return; without it Taxorio won't download either, because the tax office would send it back for completion. A new classification applies from 1 January 2026; a code that is no longer in it (for example 450000) is flagged next to the field and you need to choose the activity again. With such a code you can't download the income tax return (EPO rejects it), but you can download the VAT return — EPO only flags the code, so download it once more after choosing the new activity. An identified person does not have to state it on the VAT return, and under the flat-rate tax regime Taxorio doesn't need it at all.
- Commercial register entry — optional; if filled in, it's printed on the invoice.
The tax ID (DIČ) only appears once you've picked a VAT status — for a VAT payer and an identified person it's offered and required. See the Tax settings article for details.
Address & contact
- Street and number, Postal code and City — your registered address, printed on the invoice.
- Email — the contact email for invoicing (can differ from your sign-in email).
- Phone — shown on the invoice as a contact detail.
Bank details
- Account number and Bank code — in Czech format; together they make up the payment QR code on the invoice.
- IBAN — the account number in international format (a Czech IBAN is CZ + 22 characters).
- BIC/SWIFT and Bank name — optional, useful for payments from abroad.
If you have more than one account, manage them on their own Settings → Bank accounts tab: each account has its own name and currency, and one of them is the default. A new invoice picks up the default account; you can choose a different one when issuing it, in the Payment and VAT step. An account is never deleted, only archived — and an invoice that's already issued remembers its own payment details, so it stays unaffected by a later change or archiving. Once you have a second account, the fields above disappear here and point you to that tab instead.
Uploading your logo
Your logo appears in the top-left corner of every PDF invoice and in the header of the HTML preview.
- The Company logo card is right at the top of the Settings → Company details page.
- Click Upload logo and pick a file. It uploads straight away — nothing else to confirm, and the preview updates immediately.
- Supported formats: PNG and JPG (the server rejects SVG). Maximum file size: 2 MB.
- We recommend a horizontal logo, at least 400 × 200 px. In the invoice header it's placed into an area roughly 100–150 points wide and 30–56 points tall (depending on the chosen template), and the aspect ratio is preserved — so a square logo shrinks to fit the height and ends up looking small.
- Swap the logo with the Upload a different logo button, or remove it with Delete logo.
Where these details appear
- PDF invoice — the header, with the logo, company name, address, IČO, DIČ and bank details.
- HTML preview of the invoice in the app.
- Invoice email — the company name appears in the default subject and in the message signature.
