Create and send a lesson invoice
In Kadrella, an invoice is created from a payment: it takes the student, the lessons covered and the amount, and gets a sequential number (for example M-2026-11-000001). It carries your business’s legal details, hence the step for your company number (the SIRET in France). Invoicing is part of the Pro plan.

Step 1
Fill in your company number
Kadrella needs your company identification number before it generates an invoice: in France this is the SIRET, the field the app shows. Open "Settings" then, under "Organization", the "Settings" page. Click "Edit" in "Legal details" and enter the number and the address.

Step 2
Open the payment to invoice
In "Finance", "Student Payments", open the payment. The "Lesson Allocation" block shows the lessons it settles. Click "Get the invoice".

Step 3
Check, download or send
The preview shows the invoice as the student will get it: your details, the recipient, one line per lesson and the total. The icons at the top of the PDF download or print it. "Send via WhatsApp" sends it to the student, once WhatsApp is connected.
