The real cost of a busy service

The till isn't the problem.
What it doesn't know is.

Most restaurants we know run on a hardware POS at one counter, KOTs on paper, stock in a notebook and a WhatsApp group for bookings. It works — until the one night it doesn't.

🧾

A hardware till lives at one counter

It is a capital purchase before you've served a plate, it needs an AMC, and it can't take an order at the table, in the kitchen or from the manager's phone at home.

🔥

Paper KOTs go missing between the pass and the table

A ticket that never reaches the kitchen is a table that waits forty minutes. A ticket that never reaches the bill is food you gave away.

🥘

You know today's sales, not today's food cost

Revenue is on the till. What the paneer, the oil and the packaging actually cost per dish is in nobody's head — so the menu is priced on a hunch.

You didn't open a restaurant to reconcile tickets.
Restaurant OS keeps the floor, the kitchen and the books on one screen.

A look inside

Floor, kitchen, bill and stock. One login.

These are the modules you'll work in every service. Every one of them is live on every device signed into your restaurant.

🪑

Table floor plan

Draw your areas and tables once. See at a glance which are open, seated, billed or reserved, open a table with a tap, and move or merge parties without losing the order.

📅

Reservations

Bookings with your own slot length and table-turn time, so the plan shows what's free at eight and what's still eating. A guest book remembers regulars.

🍳

Kitchen order tickets

Every order becomes a numbered KOT the kitchen sees the moment it fires. Ticket numbers are issued in the cloud, so two tills can never print the same one.

🧾

GST billing

Bills with a rate-wise CGST/SGST summary, voluntary service charge, packaging and delivery lines, per-line tax overrides for the bar, and an A4 tax invoice that carries your GSTIN and FSSAI number.

📦

Ingredient stock & recipes

Build each dish from ingredients. Stock comes off as tickets fire, every movement is written to a ledger, and the recipe shows exactly what the dish costs to make.

📊

Day-end reports

A Z report for the day — gross sales, tax collected, discounts given and voids, by payment mode — plus food cost, so you know the margin, not just the takings.

The bill engine

What the bill gets right,
every single time.

Indian restaurant billing has rules that a generic invoicing app doesn't know. Restaurant OS encodes them, and one engine computes every bill in one fixed order.

1Subtotal of every line
2Discount — spread across lines in proportion, so the rate-wise summary still reconciles
3Service charge, packaging and delivery
4Tax, rate by rate, CGST and SGST split exactly
5Round-off to the rupee
  • 5% GST by default, with a switch for the 18% rate that applies inside hotels charging above ₹7,500 a night.
  • Service charge is voluntary and taxable. The bill prints it as a voluntary line, as the 2022 CCPA guidelines require, and taxes it as part of the value of supply.
  • Liquor sits outside GST. A per-line tax override lets the bar carry state VAT while the food stays at 5%.
  • Halves always re-add. CGST is rounded to two decimals and SGST absorbs the remainder, so the two never drift from the total.
  • Order-time settings are frozen. Changing a tax rate or service charge in Settings never re-prices a table that is already eating.
  • Bill numbers are never reused. A deleted bill leaves a permanent gap, exactly as an auditor expects.
Sample bill
Table 6 · dine-in · figures are illustrative
Paneer tikka × 2₹560.00
Dal makhani₹320.00
Butter naan × 4₹240.00
Subtotal₹1,120.00
Service charge 5% (voluntary)₹56.00
CGST 2.5%₹29.40
SGST 2.5%₹29.40
Round-off+₹0.20
Total₹1,235.00

Verified by the product's own test suite: 3,000 randomised bills where every value is exact to two decimals, rate rows re-add to the total tax, and components rebuild the grand total; 200,001 CGST/SGST splits with zero drift.

One account, every device

Two tills, one kitchen, zero double bills.

Restaurant OS is cloud-first: the cloud is the only source of truth, and every phone or tablet signed into your restaurant sees the same floor, the same tickets and the same stock, live.

🔢

Bill numbers can't collide

Two tills closing bills in the same second get two different numbers. The counter is issued inside a transaction, never read off a copy.

📉

Stock deductions can't be lost

Each ingredient's quantity is moved with an atomic increment, so two kitchens firing the same dish at once both come off stock.

🔒

A settled bill stays settled

A device with a stale copy of a table can't overwrite a bill that was already paid or voided on another one. Manager PIN approval guards voids and discounts.

Who built this

Built by TAP° Media House.

TAP° Media House is a marketing and software company working with businesses of every size, restaurants very much included. Restaurant OS is the restaurant division of TAP Revenue OS, the business operating system we run our own company on — the same cloud, the same sign-in, built for the pace of a dinner service.

Questions

Frequently asked questions.

Do I need to buy a POS machine or any hardware?

No. TAP Restaurant OS runs in the browser on any phone, tablet or laptop you already own, and it can be added to the home screen like an app. Bills and A4 tax invoices print through your device's normal print dialog.

How is GST handled on the bill?

GST defaults to 5% and the bill shows a rate-wise summary with CGST and SGST split exactly. You can switch to 18% for hotel restaurants, add a voluntary service charge (taxed as part of the supply), and set a per-line override so liquor carries VAT while food stays at 5%. Filing returns remains your or your accountant's responsibility.

Can more than one device use it at the same time?

Yes. Every phone or tablet signed into your restaurant sees the same floor plan, tickets, bills and stock, live. Bill numbers are issued so two tills can never produce the same number, and stock deductions from two devices are both counted.

I already pay for TAP Revenue OS. Do I pay again?

No. Restaurant OS is the restaurant division of Revenue OS, so any active Revenue OS plan unlocks it. Sign in at the app with the same account and it is already yours.

Does stock really come off as I sell?

Yes, if you build dishes from ingredients. When a ticket fires, each ingredient's quantity is deducted and written to a stock ledger, and the recipe shows what the dish costs to make so you can see food cost per dish and for the day.

Where is my data stored, and is it safe?

In the cloud, on Google Firestore, the same infrastructure TAP Revenue OS uses. The cloud is the single source of truth, so a device going offline or being replaced never loses a bill. Data is encrypted in transit.

Can I cancel, and what is the refund policy?

You can let the subscription lapse at the end of the period you paid for at any time. Subscriptions are non-refundable once activated, in line with our Refund Policy; duplicate charges are refunded on verification.

What is the difference between Restaurant OS and Revenue OS?

Revenue OS is the general business operating system — clients, invoices, quotations, proposals, P&L. Restaurant OS is its restaurant division: a floor plan, KOTs, dine-in billing, ingredient stock and recipe costing, built for the pace of a service. A restaurant that only needs invoices can use Revenue OS; a restaurant that needs a till should start here.
