Before you start

- Your invoices and payments are posted to the books (see Post an invoice and its payment to your books). Group 3 counts income when the money arrives.

If something goes wrong
- "The books could not read the single-tax figures for this period.": reload the page; if it stays, check that your books are set up.
- Income is ₴0.00 although you were paid: the payment is still waiting in the Posting queue. Post it first.
- Groups 1 and 2: they pay a fixed monthly amount; the card shows the month's tax and its pay-by date instead.
