Freelancers and independent consultants don't carry inventory, but they still need to quote work, invoice clients, and chase payments that come in late. LKG for Billing covers that whole cycle without the overhead built for product-based businesses.

Send an estimate before you send an invoice​

When you're pitching a project or scoping work for a new client, you usually need to quote a price before any money changes hands. The Estimates screen lets you create a formal quote — line items, pricing, terms — that you can send to a client for approval before committing to the invoice.

Estimates overview screen

This matters for service work in particular: scope and pricing often need a round of back-and-forth before a client signs off, and having a proper estimate document (rather than an email quote) keeps that conversation professional and on record.

Convert the estimate into an invoice once approved​

Once a client agrees to your estimate, you don't need to re-enter everything from scratch. LKG for Billing lets you convert an approved estimate directly into a GST-compliant invoice, carrying over the line items and pricing you already quoted. That saves you the duplicate data entry and keeps your invoice consistent with what the client actually agreed to.

Track receivables when clients pay late​

Late payment is one of the most common frustrations for freelancers and consultants — work is delivered, an invoice is sent, and the payment doesn't show up on time. The Receivables screen gives you a clear view of what's outstanding: which invoices are unpaid, how much is owed, and how overdue they are.

Receivables tracking screen

Instead of manually tracking which clients still owe you money in a spreadsheet, receivables gives you a single place to check before you follow up on a payment — useful when you're juggling several clients at once and can't afford to lose track of who's paid and who hasn't.

Built for low-volume, service-only billing​

Freelancers and small service businesses don't need product catalogs or inventory tracking — LKG for Billing works just as well without them. You can invoice purely for services (consulting hours, project fees, retainers) without ever touching the product side of the system, keeping your workflow focused on estimates, invoices, and receivables.

Reports that keep you on top of cash flow​

Freelance income tends to be uneven — a busy month followed by a quiet one — which makes it easy to lose track of where you actually stand. The invoice report and payment report give you a running view of what's been billed and what's been collected, while a simple cash flow report helps you see whether your income is keeping pace with your own business expenses, like software subscriptions or travel costs tied to client work. Having this in one place means you're not reconstructing your financial picture from bank statements and email threads at tax time.

The free plan fits a freelance workload well​

If you're billing a handful of clients a month, the offline app's Free plan is a genuinely good fit — ₹0, forever, no credit card required, no expiry. It includes 10 invoices/month, 10 customers, 20 products, and unlimited users on the same LAN network, along with complete offline functionality so you're not dependent on an internet connection to bill a client. For most solo freelancers and consultants, 10 invoices a month covers the workload without needing to upgrade. If you'd rather work from the cloud, there's also a free 30-day cloud trial with the same limits, no card required. Compare the full range of plans on the pricing page or head to download to get started.
