Calendra turns a completed appointment into an invoice, carrying the service, price and client details over from the booking. It supports cash, card, bank transfer and online payments.
Calendra turns a completed appointment into an invoice in a few clicks, because the service, price and client details carry over from the booking. It supports cash, card and online payments, and with the fiscal cash register add-on it also handles fiscal verification under Slovenian law.
Billing differs mainly by when the customer pays and whether payment is a condition for the booking.
The most common case in salons and health services. When the appointment ends, the employee opens it, confirms the services delivered and issues the invoice. The amount and the client are already filled in, so invoicing takes a few clicks instead of a fresh data entry.
Where last-minute cancellations mean lost revenue, you can require a deposit or full payment at booking. The appointment is only confirmed after successful payment, which substantially reduces no-shows.
A customer buys a package of visits and uses it over time. Each visit is deducted from the package and the remaining balance is visible on the client profile, with no separate spreadsheet to maintain.
With business clients the payer is the company rather than the person who attended. The invoice is issued to the company's details while the appointment stays linked to the individual who received the service.
Details captured at booking are reused on the invoice. Less retyping means fewer mistakes in amounts, names and tax numbers.
Because appointments and invoices are linked, you can see which services generate the most revenue and how much is outstanding, not just how many appointments happened.
With the Fiscal cash register add-on (9.90 EUR per month) Calendra supports the fiscal verification of invoices that Slovenian law requires for cash payments.
A calendar plus a separate invoicing program works, but it requires entering every detail twice.
| What we compare | Calendar plus separate invoicing program | Calendra |
|---|---|---|
| Entering client details | Once in the calendar, again in the invoicing program. | Once at the first booking, reused from then on. |
| Linking an invoice to an appointment | Manual lookup of which invoice belongs to which visit. | The invoice is attached to the appointment and client profile. |
| Prepayment at booking | Not possible without an extra payment tool. | A deposit or full payment can be a condition for confirmation. |
| Revenue by service | Requires merging two data sources by hand. | Reporting comes from the same records the appointments created. |
| Fiscal verification | A separate fiscal register or external service. | The Fiscal cash register add-on works inside the same system. |
| Preparing data for accounting | Export from two systems and reconcile manually. | One export of invoices and payments for the period. |
The appointment already carries the selected services, prices and client details.
After delivery you confirm what was actually done and adjust if needed.
