Does it handle GST correctly for Indian clients?

Yes. Your generated app captures each client's GSTIN and state, records HSN or SAC codes on line items, and splits tax into CGST/SGST for same-state clients or IGST for inter-state ones. You can ask for tweaks in plain English if your practice needs specific handling, and export invoices as PDFs for your CA.

How do clients actually pay me?

Kashvi can put a Razorpay or UPI payment link on every invoice, so a client taps the link and pays instead of you sharing account numbers. The invoice status updates to paid, so you always know what's still outstanding without a separate spreadsheet.

Can I invoice clients outside India?

Yes. You can invoice in USD, EUR, or other currencies for overseas clients while the app keeps a rupee total so your books and GST records stay consistent. Ask for whichever currencies you bill in and Kashvi wires them into the app.

Do I really get the code, or is it locked to Kashvi?

You get the full source — the front end, the database schema, the authentication, and the logic. You can download it and host it yourself. There's no proprietary runtime you're forced to stay on, so you never pay rent on your own invoicing tool.

Is there a mobile app or just web?

Both. Kashvi builds a web app and real native Android and iOS apps through React Native from the same prompt, so you can raise invoices on your laptop and check who has paid from your phone.

What happens if a generation fails?

Credits are refunded when an AI generation fails. Billing is meant to be fair — you're not charged for output you didn't get, and you can see exactly what each build costs before you run it.

Use case

Build your own invoicing and billing app for freelance work

You send an invoice, then chase it. For weeks. The client says they'll pay after the next milestone, the WhatsApp reminders pile up, and your GST number is sitting in a Google Doc you copy-paste every time. Kashvi lets you describe the invoicing app you actually want in plain English and builds it for real: a proper database of clients and invoices, your own login, a live preview you can click through, and downloadable code you keep. No spreadsheet gymnastics, no per-invoice SaaS tax on money you haven't even collected yet.

Generic invoicing tools are built for accountants running fifty companies. A solo designer, developer, writer, or consultant needs something narrower and sharper: fast invoices that look professional, GST that's correct without a chartered accountant, and a payment link that turns 'I'll pay soon' into money in your account today. Kashvi generates that specific app from your prompt, wires up a Postgres database and sign-up/login automatically, and hands you the full source so you can host it yourself and never pay rent on your own billing.

What a freelancer's invoicing app actually needs

The features matter more than the buzzwords. When Kashvi builds your billing app, you get the pieces that map to how independent work really runs — quoting a scope, tracking what's billed versus paid, and getting settled without hardware or a merchant onboarding marathon:

GST-compliant invoices with your GSTIN, HSN/SAC codes, and CGST/SGST or IGST split calculated automatically based on the client's state.
A Razorpay or UPI payment link on every invoice, so clients settle by tapping a link instead of you sharing bank details and reconciling by hand.
INR as the default plus multi-currency for overseas clients — invoice a US or EU client in USD/EUR, still keep your books in rupees.
A client directory that remembers billing address, GSTIN, and default rate, so a repeat invoice is two taps, not a re-type.
Status tracking (draft, sent, viewed, paid, overdue) and automatic overdue reminders you can nudge over WhatsApp or email.
Recurring invoices for retainer clients, PDF export for your CA, and a simple dashboard of what's outstanding this month.

From a sentence to a working app

You don't configure anything. You write what you want and Kashvi produces a real application — front end, database schema, authentication, and business logic — that you preview live and refine by asking for changes. Because it ships web plus native Android and iOS through React Native, you can raise an invoice from your laptop after a call and check whether a client paid from your phone on the train. Try prompts like these:

"Build an invoicing app for a freelance designer. Clients with GSTIN and address, invoices with line items and HSN codes, automatic CGST/SGST or IGST split, a Razorpay payment link on each invoice, and a dashboard showing total outstanding."

"Add recurring monthly retainer invoices that auto-generate on the 1st, mark them overdue after 15 days, and let me send a WhatsApp reminder with the payment link."

"Let me invoice international clients in USD and EUR while keeping a rupee total for GST, and export any invoice as a branded PDF."

"Add a client portal login where each client sees only their own invoices and can pay the unpaid ones by UPI."

You own it, and it's fair

Most billing SaaS charges you monthly or skims a cut for the privilege of holding your invoice data. Kashvi gives you the code — the database, the auth, the whole app — so you can deploy it on your own hosting and stop paying forever. Billing here is transparent: you spend credits to generate, and if an AI generation fails, the credits are refunded rather than quietly burned. Your clients, rates, and payment history live in a database you control, which matters when it's your income and your GST filing on the line.
