Who It's For

For businesses where billing is a daily headache

Freelancers and consultants

If you're sending 10+ invoices a month across multiple clients and chasing payments manually, a billing system gives you back hours every week — and follows up so you don't have to.

Small businesses with overdue payment problems

Knowing who owes you what — and sending automatic reminders — recovers money that would otherwise sit in unanswered WhatsApp threads indefinitely.

Service businesses with recurring billing

Monthly retainers, milestone payments, subscription services — a system that generates and sends invoices automatically without you doing it manually each time.

Manufacturers and traders

High volume, multiple clients, different GST structures — a custom system handles the complexity so your accounts team isn't drowning in manual work.

How It Works

From your current chaos to a system that collects for you

01

Understand Your Billing Workflow

We document your invoicing process — what you sell, how you charge, your GST structure, payment terms, and exactly what's causing delays or missed payments today.

02

Build Your System

Invoices, quotations, payment tracking, automatic reminders, and reports — all built and tested with your real client and product data before we go live.

03

Launch and Collect

Your team creates and sends invoices from day one. Automatic reminders run in the background. You see everything — paid, pending, overdue — in one dashboard.

FAQ

Common questions about custom billing systems

Will my invoices be GST-compliant?

Yes. Invoices include CGST, SGST, and IGST fields with your GSTIN, HSN/SAC codes, and all mandatory fields required for GST filing. You can share them directly with your CA without any reformatting.

Can clients pay directly from the invoice?

Yes. Every invoice includes a Razorpay payment link — clients can pay by UPI, credit/debit card, or net banking in one click. Payment status updates automatically in your dashboard the moment it's received.

What happens when a payment is overdue?

Automatic reminders go out at intervals you set — typically 3 days before due, on the due date, and 7 days after. Sent by WhatsApp or email, in your business name. You can adjust the cadence and the message.

Can I create quotations or proforma invoices too?

Yes. You generate a quotation, send it to the client, and convert it to a tax invoice when approved — without re-entering anything. The whole flow is tracked in one place.

Will I be able to see who hasn't paid?

The dashboard shows all outstanding invoices by client, amount, and how many days overdue — at a glance. No more manually cross-checking bank statements against a spreadsheet.

Can I export invoices to PDF?

Yes. Every invoice can be downloaded as a branded PDF — with your logo, business name, address, and brand colours — for your records, your CA, or emailing directly to clients.

Does it connect to my bank account?

It doesn't connect to your bank directly, but Razorpay payments are confirmed automatically the moment they're received. Offline payments — cash, NEFT, cheque — are marked manually by your team.

Can I customise the invoice with my logo and brand colours?

Yes. Your logo, business name, address, and brand colours are applied to every invoice and PDF. It looks like your business sent it — not a generic billing tool with someone else's watermark.
