Is PennyPuffin really free for businesses?

Yes. Core usage is free forever: business profile, free invoicing, free CRM and customer register, product and service management, webshop tools, orders, messages and ticketing. We only charge for optional custom module development or tailor-made implementation help.

Does PennyPuffin include free invoicing and a free CRM?

Yes. You can create and send invoices, track payments, manage your customer register (CRM), handle cases and run your webshop without a subscription. It works as a light free ERP for small businesses.
