Free plan, discounts and the end of EET

Free up to 5 customers: iDoklad, Fakturoid, Vyfakturuj and Caflou (Želva) all handle invoicing for a maximum of 5 customers on the free plan; Fakturoid and Vyfakturuj additionally offer an unlimited number of invoices. Discounts: Vyfakturuj gives 80 % off the first annual order for trade licence holders with an IČO under 2 years old, and Fakturoid offers 50 % off the first 12 months for new starters. EET was abolished as of 1 January 2023 (Act No. 458/2022 Coll.) — no self-employed person (OSVČ) is required to record sales electronically today, so ignore the „EET“ feature in any programs that still show it. Although the Ministry of Finance submitted a proposal for EET 2.0 in early 2026 with planned effect from 1 January 2027, for 2026 no recording obligation applies (verified for 2026; the legislation is currently under discussion — monitor the Tax Administration (Finanční správa) and the Ministry of Finance (MF) for updates).

Frequently asked questions

Which invoicing program is free?
A free plan is offered by iDoklad, Fakturoid, Vyfakturuj and Caflou (Želva). All of them allow invoicing for a maximum of 5 customers; Fakturoid and Vyfakturuj additionally offer an unlimited number of invoices. Money S3 has no free plan, only a demo. Once you have more than 5 clients, you need a paid plan (the cheapest being Fakturoid from 164 Kč/month with annual billing, verified for 2026).
iDoklad or Fakturoid — which is better?
For a solo freelancer Fakturoid is usually the better choice: it is simpler, has a lower entry price (from 164 Kč/month with annual billing), has an integrated data box (datová schránka) and calculates social and health insurance advance payments automatically. iDoklad (from 187 Kč/month) has advanced inventory management, an AI Financial Radar and stronger bank links, making it a good fit for a growing business with goods. You can find a detailed comparison on the separate iDoklad vs Fakturoid page.
Which program can calculate insurance advance payments?
Automatic ongoing calculation of social and health insurance advance payments is a strong point of Fakturoid (from the „Na lehko“ plan) — it helps you monitor your insurance contributions as well as the annual overview statements for OSSZ (district social security office) and the health insurance company. iDoklad prepares supporting data for the tax return, and Money S3 handles contributions within payroll and tax records. The minimum monthly advance for social insurance for a main activity in 2026 is 5,720 Kč for the January–June 2026 period, and after the amendment 5,005 Kč from July 2026 (a return of the assessment base from 40 % to 35 %, with the overpayment for January–June being refunded); for health insurance it is 3,306 Kč throughout the year (verified for 2026 per ČSSZ and VZP).
Are there discounts on invoicing programs?
Yes. Vyfakturuj.cz gives an 80 % discount on the first annual order for trade licence holders with an IČO under 2 years old. Fakturoid offers 50 % off the first 12 months for new starters. iDoklad has a 30 % discount for Money S3 users and 50 % for non-profits and selected accountants. Always verify the offer on the provider's current price list (verified for 2026).
Do I have to record sales (EET) with an invoicing program?
No. Electronic records of sales (EET) were abolished as of 1 January 2023 by Act No. 458/2022 Coll. For 2026 no recording obligation applies. A modernised EET 2.0 system with planned effect from 1 January 2027 is being prepared, but the legislation is still under discussion — so you do not need the „EET“ feature in the programs.
Do I need the desktop Money S3, or is online invoicing enough?
For everyday invoicing by a solo self-employed person (OSVČ), an online tool (Fakturoid, iDoklad, Vyfakturuj) is sufficient. Money S3 is a „heavier“ desktop solution sold under a one-off licence (Basic from 2,990 Kč excluding VAT) — it is worth the investment when you want to keep full-fledged accounting locally on your own PC: both tax records and double-entry bookkeeping, inventory and payroll (verified for 2026).
