Meet Maya — a bakery owner who was drowning in spreadsheet chaos until she discovered one-click invoice generation
Every single morning, Maya loses 2 hours to:
"30 minutes to create ONE invoice. Got the total wrong. Sent Mr. Sharma someone else's invoice by mistake. He called confused — I wanted to cry."
— Maya, after another exhausting day
Today, Maya creates perfect invoices in ONE CLICK:
What Maya Got Back Today:
"I click one button. A perfect invoice appears. I got my evenings back."
You're not buying a "CRM." You're buying back 2 hours daily, eliminating calculation mistakes, and getting one-click invoices instead of 30-minute manual work.
No download. No migration. Just open Google Sheets and click.
Follow the setup, marker, and automation walkthrough to build your first invoice flow.
Open Sheets, select customer from dropdown (or add new one in 10 seconds). Their address, email, and GSTIN auto-fill.
Select products, enter quantities. Price, tax, and subtotal appear instantly. Check stock before confirming.
Add 10% discount. Grand total recalculates automatically. No manual math, no mistakes.
One click. Professional invoice created in Google Docs with your branding. Send to customer. Mark paid when done.
DocMaster runs entirely inside YOUR Google workspace. We never see, store, or touch your invoices, customers, or orders.
Codeinate.com never stores your invoices, customer names, or order data. Everything stays in your Google Sheets and Docs.
DocMaster runs as a Google Sheets add-on using Google Apps Script. All processing happens inside Google's infrastructure under YOUR account.
Your Sheets, your Docs, your Drive folder. You can export, backup, or delete everything anytime. DocMaster just automates the clicks.
