# Keysvo > Keysvo is free arithmetic and a paid deal register for the person buying an existing small business in the United States: a dentist buying a practice, a first owner buying a laundromat or a restaurant, or the buyer of an unnamed existing business. The acquisition cost calculator turns price, SBA note, seller note, working capital and closing costs into cash at the keys and monthly debt service; the due diligence checklist sheet tracks one target's documents, price ratios and days to close. Keysvo Pro, $14 a month, keeps every target, offer, diligence item and lender. It publishes no valuation opinion, no legal advice, no loan products and no listings. ## What this is for - The person buying an existing small business in the United States: a dentist buying a practice or buying in, a first owner buying a laundromat or a restaurant, or anyone buying an established business and keeping the deal in a spreadsheet and an email thread,Not the seller, not a broker or M&A advisor, not a startup founder working a cap table, not a lender's customer comparing loans, not a franchise buyer and not a person buying a house ## Tools -
