An offer that the customer
does not have to check elsewhere.

Who it is for

Installers and smaller developers who prepare offers for homes, businesses and municipalities. You need a fast, repeatable and defensible assessment that does not take your technician's time on every enquiry.

What we need you to enter

The form is short. Leave blank what you do not know — the platform will ask for the missing input and will not fill it in with an estimate.

• Installation voltage level — determines the tariff regime.
• Battery capacity (kWh or MWh — the price is calculated from the capacity) and inverter power (kW or MW — for the calculation only, not for the price).
• Round-trip efficiency per the technology datasheet.
• PV capacity, if it is a co-location or a retrofit.
• Client consumption for behind-the-meter installations.

What you get — an independent assessment

• An assessment under the letterhead of an independent platform — not under yours, so it carries different weight with your customer. Martin Michalíček signs the Quick check and the full DD.
• The same price and the same method as if your customer had ordered the assessment themselves. That is why they can trust it.
• A basis that holds up when the customer has the offer checked elsewhere.
• Critical findings that reveal a problem before the customer finds it after signing.

What you get — the platform under your brand

Don't want your own software or an analyst? Rent bessaudit.com. You do the calculations yourself, under your own logo.

• The same engine and the same market data (ČEPS, OTE, ERÚ) as in our assessments. You change the project inputs, not the market data.
• A report with your logo, saved projects, and an input fingerprint on every output.
• Recalculations and trying it out on sample data are free — you pay only for a generated output.
• This is not an independent assessment. The output carries the sentence “Calculation prepared by ‹your company› on the bessaudit.com platform. This is not an independent assessment.” You can order a signed independent assessment for your customer separately.

What to watch out for

• Enter the capacity in the unit you have in the datasheet — the form converts it. Mixing up kWh and MWh shifts the result by three orders of magnitude, so the platform checks whether the value is within the expected range.
• An oversized battery lengthens the payback. The assessment shows this before you learn it from the customer.
• Aggregation of technical flexibility has been open since 1 August 2026, which opens ancillary services to sources below 1 MW — via an aggregator. A standalone bid to the reservation market has a minimum of 1 MW.

FAQ

Can we give the output to the customer under our own letterhead?

Yes, with the platform under your brand (CZK 5,000 a month + a fee per output). It is then your calculation, not our assessment — the output says so in one sentence. An independent bessaudit assessment always carries our brand and signature.

Can we handle a batch of projects at once?

The B2B API is intended for repeated assessments. You will find the details and the interface on the B2B API page.

What does it cost at larger volume?

An independent assessment costs the same for every project — we don't give volume discounts. At larger volumes the platform under your brand pays off; for connecting to your own tools there is the B2B API (CZK 20,000–80,000 a month).
