A billable-hours calculation answers one practical question: how much client-approved work should be invoiced before collection risk, write-downs, or unpaid time change the final yield. In Czechia, the working total is normally stated in CZK, so each time category needs a rate in Czech koruna, a billable-hour count, and a clear decision on whether the provider is a Czech VAT payer.
The result gives you a pre-tax service total, any VAT amount that applies, and the final client-facing invoice amount. It also helps separate productive billable work from admin, sales, internal review, and rework that should stay outside the invoice unless the client agreement makes it billable.
Czechia's standard VAT rate is 21%, and it applies to sales of goods and services unless the VAT Act assigns the supply to a lower rate. Czechia also has a 12% reduced VAT rate for listed goods and services, so ordinary professional time should not be treated as reduced-rate unless the service is specifically listed in the VAT Act annexes.
VAT is added only when the provider is a VAT payer or voluntarily registered. Czech-established businesses generally remain exempt if domestic turnover does not exceed CZK 2,000,000 in the previous calendar year or CZK 2,536,500 in the current calendar year. For that turnover test, the relevant amount is consideration excluding VAT, not gross invoice totals including VAT.
Start with each billable work category: approved hours multiplied by the agreed hourly rate. For example, a Prague consulting project includes 18 approved advisory hours at CZK 2,200 per hour and 11 approved documentation hours at CZK 1,600 per hour. The pre-tax service total is CZK 57,200.
If the provider is a Czech VAT payer and the service uses the 21% standard VAT rate, VAT is CZK 12,012 and the invoice total is CZK 69,212. If the provider is not a VAT payer, the client-facing service total stays CZK 57,200 and VAT is not added as a separate invoice charge.
A one-off calculation is enough when you have approved hours, agreed rates, a known VAT position, and no dispute over what the client pays for. It also works for a quick quote check before sending a draft invoice or comparing two rate structures on the same project.
A managed workflow is better when time comes from several people, tasks, or tools. Everhour Time Tracking captures task and project hours through timers or manual entries, supports approvals and locked periods, and gives the billing reviewer a cleaner handoff before invoice creation or payroll review.

Czech billable totals are normally stated in CZK because the Czech National Bank issues banknotes and coins in the Czech Republic and publishes official exchange-rate data in CZK. If a client contract uses another currency, keep the conversion method and exchange-rate date clear so the CZK accounting record remains traceable.
Add 21% VAT when the provider is a Czech VAT payer or voluntarily registered and the service is not assigned to a reduced rate by the VAT Act. Do not add VAT simply because the calculation has a tax field. Non-payers invoice the agreed service amount without a separate Czech VAT charge.
No country-wide billing increment is prescribed for professional time. At least for legal time fees, the payable unit is the unit agreed with the client; for Czech lawyers using a time-based contractual fee, the agreed rate is payable for each commenced hour or other agreed time unit unless agreed otherwise.
For paid supplies of goods or services, Czech rules require payment within 30 days from receipt of the invoice or equivalent request, or from service delivery or acceptance where the invoice date is not determinative. Private-sector terms longer than 60 days are allowed only when not grossly unfair to the creditor.
The common mistake is applying VAT to the wrong base. Czech VAT turnover is tested on consideration excluding VAT, and invoice VAT is calculated after the pre-tax billable total is known. Multiplying hours by rates, adding non-billable time, and then treating the gross amount as the taxable base distorts both pricing and threshold review.
Everhour Time Tracking captures task and project hours through live timers or manual entries, then feeds timesheets, reporting, budgeting, invoicing, and payroll review. Admins can use approvals, locked periods, reminders, and timer rules so invoice review starts from controlled time records rather than scattered notes.
Everhour billable and non-billable time lets admins set billing status at the project level and mark specific tasks non-billable inside a billable project. Reports can show billable time, non-billable time, billable amount, and cost by member or task for cleaner invoice review.
Track task time, approve entries, and lock billing periods before totals move to the invoice. Everhour gives Czech project teams a cleaner long-term path from recorded work to billed revenue.
