Honest answer: for invoicing, free AI isn't the win — free invoicing software is. Wave and Zoho Invoice both have genuinely usable free tiers and they handle the maths, numbering and VAT correctly, which is where a language model will quietly let you down.
Where AI earns its place is the quote copy: the scope description, the assumptions, the exclusions that stop a job creeping. Draft that with an assistant, paste it into the invoicing tool. Split the job between the two and you get accurate numbers and quotes that don't cost you an evening.
