Billdu's quote generator is part of a broader invoicing and business-management app — a reasonable choice if you want quoting, invoicing, and payments in one account, more than you need for one quick quote.
Billdu's strength is the connected workflow — a quote can become an invoice once accepted, all inside one account with saved client records. That's genuinely useful if quoting is a regular part of your business and you're already tracking client relationships in one place.
SMBkits' quote generator skips the account and the connected workflow: describe the job, get a clean, professional quote or scope-of-work document, and download it. It's built for the one-off quote, not an ongoing quoting-to-invoicing pipeline.
There's a real workflow gap worth naming honestly: once a quote from SMBkits is accepted, there's no automatic hand-off to the Invoice Generator — you'd re-enter the details there separately. For occasional quoting, that's a minor extra step. For a business quoting and invoicing the same clients repeatedly, Billdu's connected system saves that re-entry every time.
If quoting-to-invoicing is a recurring workflow for your business, Billdu's connected account earns the setup. If you need one clean quote today without adopting new software, the free generator does that specific job.

No — there's no account or saved data connecting the two. Once the quote is accepted, use the separate Invoice Generator to create the invoice for the job.
The generator uses Google's Gemini API to draft the quote text from what you enter — see the Privacy Policy for details on how that's handled.
