WatCoreLite Guide

Short, focused guides — from installing WatCoreLite to running invoicing and payments day to day.

Getting Started

Install WatCoreLite and get your business set up.

Invoicing & Payments

Create, finalize, and get paid on invoices — plus quotations that convert straight into them.

How to create an invoice

Step-by-step: build a draft, add line items and tax, and finalize it into a real, numbered invoice.

Invoice status explained: Draft, Pending, Paid, Void

What each invoice status means, when it changes, and what you can and can't edit at each stage.

How to convert a quotation into an invoice

Turn an accepted quote into a draft invoice with frozen totals — no re-typing line items.

Recording and tracking invoice payments

Log payments by method, handle partial and overpayments, and see the balance update automatically.

Returning items on a sold invoice

Refund just the items a customer brought back, without voiding the whole invoice.

How to share an invoice via WhatsApp, email, PDF, or print

One-click WhatsApp and email sharing, a downloadable PDF, or print straight to A4 or a receipt printer — no re-exporting required.

Printing invoices: A4 pages and 58mm/80mm receipt printers

See exactly what will print before it does, choose a full A4 page or a small counter slip, and print with one keystroke when you're in a rush.

Keyboard shortcuts and rapid billing

Start an invoice, scan product codes line after line, and print — without ever reaching for the mouse. Built for a busy retail or restaurant counter.

AI Fill: turn an order or bill into line items automatically

Paste a customer's order or a supplier's bill into the AI you already use, and get back ready-to-review line items — matched against your real catalog, never guessed at.

Setting up direct WhatsApp sending

Send invoices and quotations straight to a customer's WhatsApp with one click, using your own Meta WhatsApp Business API account.

Setting up direct email sending

Send invoices and quotations straight to a customer's inbox with one click, using your own email account — Gmail, Outlook, Yahoo, Zoho, or a custom domain.

Enquiries

Track every lead from first contact to a quote or invoice — so a follow-up never quietly falls through the cracks.

Quotations

Send estimates, track acceptance, and turn a yes into an invoice.

Recurring Billing

For gym memberships, tuition, mess, or any customer billed on a repeating cycle — see who's due at a glance.

Customers

Your contact list, with full invoice and payment history attached.

Products, Services & Stock

A shared catalog for everything you sell, with optional stock tracking.

Staff & Salary Slips

Track what you pay each staff member and turn it into a professional salary slip.

Cash Register & Expenses

Daily cash-drawer reconciliation and tracking money going out of the business.

Reports

Sales, stock, cash, and more — each exportable to Excel or PDF.

GST & Compliance

For Indian GST-registered businesses — a GSTR-1-ready export, done correctly, with no separate filing software required.

Billing & Licensing

Pricing, the free trial, and activating a license key.

Backup & Data

Your data lives on your machine — back it up, restore it, or move it.
