Free plan to start

Bill up to 25 customers on the free plan — enough for most freelancers to get started with zero upfront cost

GST-ready by default

Every invoice is generated with the correct tax treatment and HSN/SAC code, ready if a client asks for GST-compliant billing

See exactly where every rupee comes from

One screen shows every client, every invoice, and every payment, updated in real time — no need to open a bank app to know what you actually earned

Know which clients are ghosting you

See every client’s real status — paid, overdue, or gone quiet — and send the reminder yourself before an invoice is quietly forgotten

Run your whole practice from one login

Every client, invoice, and reminder lives in the same place on your phone, so nothing depends on a notebook or a scattered set of chats

How billing runs here

Get Paid Without Sending a Single Follow-Up Message Yourself

Let the reminders do the uncomfortable part of freelancing.

  1. Automatic Due Date Reminders

    Automatic reminders go out before and after the due date, so you never have to ask twice.

  2. WhatsApp Invoice & Payment Link

    Send the invoice and a payment link in the same WhatsApp chat you already message the client on.

  3. GST-Correct Invoices by Default

    Every invoice generates GST-correct by default, whether you remember to think about it or not.

  4. One-Screen Earnings Dashboard

    One dashboard shows total earnings, pending payments, and every client’s history in one screen.

  5. Invoice With Payment Trail

    Every job gets a proper invoice with a payment trail, so a payment dispute is settled by pulling it up.

From the first invoice to the last renewal, it runs on one shared record built for how your business bills.

I am a one-person graphic design studio. I used to make invoices in Canva and then message clients separately asking for payment. It felt awkward every time. Now the invoice and the payment link go out together on WhatsApp, and reminders happen without me having to type anything. It genuinely changed how comfortable I feel asking to be paid.

I write long-form content for about 15 clients on and off, mostly one project at a time, no retainers. Chasing a 8,000 rupee payment felt embarrassing enough that I would sometimes just let it go unpaid. I have stopped writing off small invoices since the reminders started going out for me instead of me having to ask twice.

As a freelance developer I bill in USD sometimes and INR other times, and GST compliance always felt like something I would figure out "eventually." Never did, until a client actually asked for a proper GST invoice and I had nothing ready. Now every invoice is GST-correct by default whether I remember to think about it or not.

I do voiceover and audio editing work and used to just quote a flat number over WhatsApp with no real paper trail, which was fine until a client claimed they'd already paid a project I could not prove they hadn't. Now every job has a proper invoice with a record behind it, and that particular argument cannot happen again.
