Frequently asked questions
Only VAT-registered businesses can issue credit notes?
Non-VAT businesses can issue them as a reduction record, but the VAT law mandates them for VAT-registered sellers.
Must credit notes reference the original invoice?
Yes — invoice number + date must appear. Flowly does this automatically when you convert from an invoice.
Full return — can I credit the whole amount?
Yes. Full-value credit note → full output-VAT reversal on your PP 30 filing.
