“Bhaiya, paneer khatam ho gaya. 120 guests are still in the queue.”
Running out mid-event
Quantities sized on gut feel. Too little and the reputation goes. Too much and the margin goes.
For catering & tent house businesses in India
Know exactly how much to cook, who owes what, and who's allowed to see it.
UtsavOS runs every booking from first enquiry to the final rupee. A confirmed guest list becomes an exact shopping list, and a quotation becomes a WhatsApp message.

The problem
How much to cook for 500 plates?
Experience, paper arithmetic, and a prayer.
Every caterer and tent house in India knows these three moments. UtsavOS is built so they stop happening.
“The 300 chairs went to the other wedding. Didn't anyone check?”
Two events, one stock of chairs
Rental stock promised twice because the booking diary and the godown never spoke to each other.
“Did the Mehta family pay the second instalment or not?”
Money that lives in someone's head
Advances, dues and vendor bills spread across notebooks, UPI screenshots and one person's memory.
See it think
Guests in. Shopping list out.
Move the guest count and pick the menu. UtsavOS scales every recipe, nets it against what's already in your store, and sorts the shortfall by vendor. All of it happens before anyone picks up a phone.

Menu
Portions learn from your own events. Every logged event sharpens them, so you're not stuck with someone else's thumb rule.
Raw material, netted against stock
Purchase orders, drafted by vendor
Illustrative numbers from a demo kitchen. Your recipes, stock and vendors drive the real thing.
One connected system
From the first phone call to the last returned chair.
Every module reads and writes the same live data. When a booking is confirmed, the kitchen, the godown and the books all know about it straight away.
Rental calendar
Double-booking, structurally impossible.
Tents, tables, crockery and chairs are reserved against what you actually own. A clash is caught before you confirm the booking, not on the morning of the event.
Quotations
A quote is now a WhatsApp message.
Branded, GST-ready and auto-numbered. One tap sends it to the client's phone.
Payments
Dues collect themselves.
Each balance due becomes a Razorpay link sent on WhatsApp. When it's paid, it reconciles into the books on its own.
Order changes
A second pair of eyes on the same day.
When the guest count changes on the event day, someone other than the person who proposed it has to sign off.
Event P&L
Profit, per booking.
See revenue against food, labour, sub-rentals and transport on the day an event closes, not at season-end.
Stock & vendors
The oldest batch goes out first. Nobody has to remember to pick it.
FEFO (first-expiry, first-out) drawdown, a preferred vendor for every material, and purchase orders that arrive already sorted by who supplies what.
One app, five roles
Your chef sees quantities. Your accountant sees money. Nobody sees what isn't theirs.

Works where your team works
On the accountant's laptop and the field crew's phone, even with no signal.
Your desk and your crew work on the same data. A dispatch logged in a basement banquet hall syncs the moment a bar of network comes back.
- Installable on any phone. Add it to the home screen with one tap. There's no app-store update to wait for.
- Offline-first. Checklists logged with no signal sync automatically, and nothing gets lost.
- Your data, walled off. Each business is isolated at the database level, not just behind a login screen.

Made for India
Built for how an Indian business actually bills, collects and files.
Thousands and lakhs, CGST and SGST, UPI and cheques, a CA who wants it in Tally. UtsavOS treats all of it as normal, so there's nothing to work around.
GST invoice
CGST + SGST, or IGST. Worked out, not typed.
Mark a quote as interstate and the tax moves to IGST on its own. Totals round off to the rupee, and every invoice is numbered automatically.

Thousands and lakhs, everywhere
₹85,000 for a mehendi, ₹4,86,200 for a wedding, never ₹486,200. Every quote, invoice, report and WhatsApp message groups money the way your clients read it.
Paid the way India pays
Record UPI, cash, cheque, bank transfer or card. Or send a Razorpay link on WhatsApp, and it reconciles itself once paid.
A clean handover to your CA
Sales and receipt vouchers export as a CSV that imports into Tally. The GSTR-1 summary splits B2B from B2C by GSTIN, in PDF or Excel.
Built with the DPDP Act in mind
Client consent is recorded, a client's data can be exported in one piece, and deletion requests are logged, as the DPDP Act 2023 expects.

Behind the mark
A tent peak, because every utsav starts with one.
Before the first guest arrives, the shamiana goes up. It covers the kitchen, the stage and the crowd, and keeps the whole celebration under one roof. That's the job UtsavOS does for your business.
See it on your own bookings
Bring one real booking. We'll show you the whole system running on it.
No sample data and no slides. We use your own guest list, your vendors and your numbers. If it doesn't save your team real time on a real booking, it isn't worth your time.
- No more midnight calls about missing paneer.
- No more guessing who's already paid.
- No more one person carrying the whole booking in their head.
