Daily, from European Central Bank data. Rates only affect the combined
totals on your dashboard — each invoice always keeps its own currency.
You can also refresh manually from Settings.
That's intentional: invoices keep a snapshot of the details they were
billed with, so your records stay accurate. Client edits apply to
future invoices only.
Go to Settings to upload a logo (PNG or JPG) and fill in your company

No — invoices are permanent records for accounting compliance. Mark an
invoice as cancelled instead; it stays out of your totals.
