Invoices

There are two things here. The Invoices page is your own record of what a student owes and whether it arrived. Separately, if you connect an invoicing provider, Matheia issues a proper invoice document to the student every time a session is paid for.

Creating an invoice

Go to Invoices in the sidebar and click "Add invoice." Select a student — for linked students, buyer details are pre-filled from the student-owned billing profile mirrored into the relationship record. Enter the amount, currency, issue date, due date, and an optional title and notes. Save to create the invoice.

Calculate from sessions

Instead of entering amounts manually, use the "Calculate from events" feature. Select a date range and click "Load events." Matheia finds all completed sessions for the selected student in that period and calculates totals from the product or session pricing attached to those sessions. Click "Apply" to populate the invoice amount and auto-generate a descriptive title. You can adjust the amount before saving.

Invoices issued to students

With a provider connected in Settings, a paid session produces a real invoice — numbered, carrying your billing details and VAT rate, and issued in the currency the student paid in. Matheia can email it to them as well. A refund produces a credit note against the original. These documents are generated for you; you do not create them by hand, and they are separate from the entries you add on this page.

  1. 01Connect a provider under Settings, then Invoicing.
  2. 02Turn on issuing an invoice when a student pays.
  3. 03Take a booking as usual — the invoice is issued once payment clears.
  4. 04Find the document against the payment, and download the PDF if you need it.

Invoice status

Invoices move through statuses: Pending (just created), Sent (forwarded to the student or accounting system), Paid (payment received), or Overdue (past due date, unpaid). Update the status manually as payments come in. Students see their invoices and current status in their portal.

Manual entries

Invoices you add yourself stay internal: they record an amount, a due date and a status so you can see what is outstanding. They are useful for work paid outside Matheia — cash after a lesson, a bank transfer, an arrangement predating the platform. They are not tax documents, and they are not sent anywhere.

Common questions

Do I have to create an invoice for every paid lesson?
No. If you have connected a provider, invoices for sessions paid through Matheia are issued automatically. The manual page is for everything else.
What happens if I refund a student?
A credit note is issued against the original invoice, so your records stay consistent without you correcting anything by hand.
Which currency is an invoice issued in?
The one the student actually paid in. Nothing is converted.
Can I change a manual invoice after saving it?
Yes. Manual entries are your own record and can be edited or deleted at any time.
