I have 2 companies that I utilize one billing system for. PDFfiller allows me to edit the logo and name on the invoice to reflect the 2nd company. Saves an enormous amount of time and confusion for the clients that belong to both companies.
TIMMY HENDRIX
Worth the money! The software is very easy to use from a smartphone or computer. Most people don't own a fax machine, so this feature is very handy! The subscription is necessary, but now with many places of business using editable PDFs, it's not needed as often as I'd like.
