Pricing

You pay for certainty, not consultant hours

You get the audit as a one-off, by segment. First an indicative output for free, then you choose the depth. Payment by bank transfer or against an invoice.

VAT: we state prices excl. VAT and incl. VAT, so the final amount is clear before you order. Sun.Energy Holding s.r.o. is not registered for VAT — VAT is CZK 0, so the prices shown are final and the amount including VAT equals the amount excluding VAT. The rate and the VAT registration status are held by the engine (assumption register, key DAN.DPH.SAZBA_ZAKLADNI, and the entity card), not by the text on this page.

How the price is built

Two independent things: segment sets the price of the automated audit, depth sets how much human work goes into it. You always start for free.

How you pay

🏦 By bank transfer  — payment request with a QR code and a variable symbol 🧾 Against an invoice  with 14-day payment terms (companies and municipalities with a company ID) 💳 By card  — we are adding the payment gateway, not offered yet

A proforma invoice (payment request) is not a tax document; we issue a receipt for the payment received once the funds are credited. The ordered output is unlocked once the payment is credited, not when the document is issued — also for payment against an invoice. Prices are indicative under the current model and do not constitute an offer within the meaning of § 1732 of the Czech Civil Code.
