Use case

Build a Quotation & Estimate App Freelancers Actually Send From

You quote a design retainer over WhatsApp, the client says yes, and now you are copy-pasting the same line items into an invoice at 11pm with the wrong GST rate. A quotation app should end that. With Kashvi you describe the estimate-to-invoice flow you already run in your head, and it builds a real working app — your own Postgres database, client login, live preview, and full source code you download and keep. No proprietary runtime, no lock-in, and the same build runs on the web and as a real Android and iOS app.

Most quotation tools are built for teams with a sales department. Freelancers and solopreneurs need something narrower and sharper: send a clean estimate fast, let the client approve it, and turn that approved quote into an invoice with a payment link in one tap — without re-typing anything. That single conversion, quote to invoice, is where generic apps waste your evenings.

What a freelancer's quotation app really needs

The features that matter here are specific to solo work: you are the salesperson, the accountant and the delivery team, so the app has to remove steps rather than add approval layers. Kashvi builds exactly the fields and flows you ask for, so your quote looks like your business — your logo, your terms, your GST number.

  • Line-item estimates with quantity, rate, and per-line or per-total GST (CGST/SGST split for in-state, IGST for out-of-state clients).
  • A shareable quote link the client can open on WhatsApp and Accept or Request Changes — with a status trail so you know it was seen.
  • One-click convert: an accepted quote becomes an invoice, carrying over every line item, tax and discount, plus a Razorpay/UPI payment link.
  • Reusable service catalogue so your standard packages (a logo pack, a month of retainer, a photo shoot) drop in without re-typing rates.
  • Auto quote numbering, validity dates, advance-vs-balance terms, and a running list of pending, accepted, and expired quotes.
  • Your own client database — contacts, past quotes, and what each client typically pays — instead of scattered PDFs in your downloads folder.

How Kashvi builds it from a prompt

You type what you want in plain English. Kashvi generates the database tables (clients, quotes, line items, invoices), the login so only you and your clients see the right screens, and the UI — then shows a live preview you can click through immediately. When a generation fails, credits are refunded, so you are never charged for a broken build. When it is right, you export the full code: it is a normal codebase you or any developer can host anywhere. Below are prompts a freelancer could type as-is.

"Build a quotation app where I add line items with rate and GST, generate a quote PDF with my logo, and send a link the client can approve on their phone. Show me all pending and accepted quotes on a dashboard."

"When a client accepts a quote, let me convert it to an invoice in one click with a Razorpay payment link, and split GST into CGST and SGST for clients in my own state."

"Add a service catalogue with my standard packages and prices so I can build a new estimate by picking items instead of typing them, and let me set an advance percentage the client pays first."

"Make an Android and iOS version so I can send a quote from my phone right after a client call, and text me when a quote is accepted."

Fair billing and code you own

Pricing is in INR and Razorpay/UPI is first-class, so paying for the tool — and getting paid through the tool — both work the way an Indian freelancer expects. Because you download the source, there is no monthly hostage fee to keep your own quotes: if you outgrow Kashvi or want a developer to extend it, the app is yours. Transparent, credit-based billing means you see what each build costs, and failed AI generations are refunded rather than silently charged.

Questions

Frequently asked

Can the app handle GST correctly for different clients?
Yes. You can ask Kashvi to add per-line GST and to split it into CGST and SGST for clients in your own state or apply IGST for out-of-state clients, and to show your GSTIN on the quote and invoice.
Does an accepted quote really become an invoice without re-typing?
That is the core flow. You describe it in your prompt and Kashvi builds a convert action that carries every line item, tax and discount from the accepted quote into a new invoice, then attaches a Razorpay payment link.
Can my clients approve a quote from their phone?
Yes. The app can generate a shareable link you send over WhatsApp, and the client opens it to Accept or Request Changes. You get a status trail showing what has been seen and approved.
Do I get an Android and iOS app or only a website?
Both. Kashvi builds real React Native apps for Android and iOS alongside the web version from the same prompt, so you can send a quote from your phone right after a client call.
Do I own the code, or am I locked into Kashvi?
You own it. You download the full source — a real database, login and UI — and can host or extend it anywhere. There is no proprietary runtime holding your quotes.
What happens if an AI generation fails?
You are not charged for broken builds. Kashvi uses transparent credit-based billing and refunds credits when a generation fails, so you only pay for work that actually lands.
