Create invoices, export PDFs, track payments, and use calculators, PDF tools and Excel templates — without the complexity of full accounting software.re. No signup required.
Hey Product Hunt! 👋
I built SoloCalcKit because invoicing and everyday business tools often feel more complicated than they need to be. Freelancers and small businesses should be able to create a professional invoice, export a PDF, track payments and handle simple business tasks without learning a full accounting platform.
SoloCalcKit combines a simple invoice workspace with practical calculators, PDF tools and Excel templates in one place. You can start free, and Pro is there for users who need unlimited invoicing and automation.
My goal is to keep it fast, simple and genuinely useful.
I’d really appreciate feedback from freelancers and small business owners — especially on the invoicing experience. What would you add or improve?
