Kwota: a Nigerian plumber talks through the job in Pidgin, and the customer gets a priced quote on WhatsApp

Description and use

Kwota speeds up quoting for Nigerian artisans by converting voice notes into PDF quotes and opening WhatsApp with the message ready to send.

Problem

Artisans lose jobs because quoting is slow, unpaid, and handwritten, leading to mistrust and missed opportunities.

Outcome

Kwota reduces quote turnaround from days to minutes, improves trust with a clean PDF, and keeps all data local, enabling artisans to win more jobs with a low monthly fee.

Workflow

• 1. Artisan walks the job and records a voice note describing the work and quantities.
• 2. Kwota transcribes the note using NaijaVox‑2.0 and extracts numbers with numbers.py.
• 3. Gemma 3 12B drafts line items from the artisan’s price list and returns JSON.
• 4. The UI shows every quantity heard and flags any uncertainties for confirmation.
• 5. Artisan reviews and edits the quote if needed.
• 6. Kwota generates a PDF quote and a wa.me link with the quote pre‑typed for WhatsApp.
• 7. Artisan sends the quote to the customer before leaving the site.

Evidence

Kwota transcribes it (Pidgin, Yoruba, Hausa, Igbo or Nigerian English) and maps it onto his own price list.

It shows every number it heard and the exact words each came from, so he can confirm.

One tap makes a clean PDF quote with his business name, and opens WhatsApp with the quote already typed out for the customer.

Kwota never invents a price. Every naira on the quote comes from the artisan's own editable price list, or from an amount he said out loud, and that line is flagged so he double-checks it.
