Invo handles invoicing, quotes, expenses and VAT for South African small businesses. Tax invoices follow SARS' rules, VAT is worked out at 15%, and invoices can go to clients as a WhatsApp link, so they don't get lost in an inbox.
I build and run Invo from Johannesburg. The South African rules are part of the product rather than an add-on: each invoicing feature is checked against what SARS asks for as it's built.
It's new, so there are no customer logos on this site yet. If you try it, email info@getinvo.co.za or send a WhatsApp, and I'll read it and reply myself.
