Business Software for Solopreneurs — One App to Run It All

As a solopreneur you are the sales team, the delivery team and the accounts department all at once. KukBook puts GST invoicing, double-entry accounting, expense tracking, quotations and a light CRM in one cloud app, so you spend less time on admin and more on the work that pays. It runs in any browser, works offline as a PWA, and starts free for 90 days with no credit card — priced in rupees for India and the GCC.

Frequently asked questions

Is KukBook free to start, and do I need a credit card?

You get a 90-day free trial with no credit card required, so you can raise invoices, track expenses and see your reports before paying anything.

I'm a one-person business — is this too much software for me?

No. You can use just invoicing and expenses to start, and turn on accounting, quotations or CRM only when you need them. It's designed to be usable by a single owner with no accountant.

Can I send invoices from my phone?

Yes. KukBook works on mobile and desktop with the same data, so you can raise and share a GST invoice from your phone and it appears in your books instantly.
