GST-Ready Hotel Billing Software for Indian Hotels

Running billing for a hotel in India is nothing like billing for a shop. A single guest stay can include the room charge, restaurant bills, room service, laundry, a spa visit, an advance paid months ago, a discount at checkout, and a company that pays for only part of it. Every line of that bill has to carry the right GST rate, the right SAC code, and a proper tax invoice that the guest's company can actually claim credit on. Get any of it wrong and the front desk spends checkout arguing with guests while the accountant spends month-end fixing folios by hand.

GST-ready hotel billing software is software built around this reality: it connects reservations, guest folios, room and restaurant charges, payments, and tax invoices in one system, so the bill that comes out at checkout is correct the first time. This guide explains the GST rules your billing has to follow — the room tariff slabs, SAC codes, restaurant rules, and reports — and what to look for in billing software for Indian hotels.

Quick answer: What is GST-ready hotel billing software? GST-ready hotel billing software is billing software designed for hotels that applies India's hotel GST slabs to room charges (no GST below ₹1,000, 5% up to ₹7,500, 18% above it), prints tax invoices with GSTIN and SAC codes, handles room and restaurant charges on one guest folio, and produces the billing reports a hotel needs for GST returns.

Tax rules change. The rates below reflect GST notifications in force as of October 2026 — confirm your hotel's exact setup with your chartered accountant.

What are the current GST slab rates for hotel rooms in India?

Direct answer: hotel GST is charged on the declared room tariff per night, in three slabs.

Room tariff per night	GST rate	Input tax credit (ITC)
Below ₹1,000	Nil (exempt)	Not applicable
₹1,001 – ₹7,500	5%	Not available
Above ₹7,500	18%	Available

Three details here catch hotels out:

The middle slab changed recently. From 22 September 2025, the 56th GST Council cut the rate on rooms up to ₹7,500 from 12% to 5%. Many billing guides and old software defaults still show 12% — if your software hasn't been updated, you are overcharging guests.
The slab is decided by the declared tariff, not the price the guest actually paid. If a ₹8,000 room is sold at a ₹6,500 promotional rate, the bill still falls in the 18% slab because the declared tariff is ₹8,000.
ITC follows the slab, not the hotel. A mid-range hotel charging 5% cannot claim input tax credit on its purchases. A luxury hotel charging 18% can. This is why the slab has to be right on every folio — it decides both the guest's bill and the hotel's own tax position.

What SAC codes and HSN details must appear on a hotel invoice?

Direct answer: hotel invoices should show the correct Service Accounting Code (SAC) for each line, and HSN/SAC digit reporting follows your turnover.

Service	SAC code
Hotel accommodation (rooms)	996311
Restaurant, cafe, room service, takeaway (non-specified premises)	996331
Food services supplied by hotels, inns, guest houses	996332
Hostel / paying-guest accommodation	996321 / 996322
Camp site services	996312

On reporting: hotels with aggregate turnover up to ₹5 crore report HSN/SAC at the 4-digit level in Table 12 of GSTR-1 (mandatory on B2B invoices); hotels above ₹5 crore must use 6-digit codes on all invoices. Wrong classification can lead to demands for differential tax with interest, so billing software that pre-fills the right SAC per charge type saves real trouble.

A proper GST tax invoice for a hotel should show: hotel name, address and GSTIN; invoice number and date; guest or company name (and company GSTIN for B2B stays); check-in and check-out dates; description of each service with its SAC; taxable value; CGST + SGST breakup (intra-state) or IGST (inter-state); and the total.

How does GST apply to restaurant and food bills inside a hotel?

Direct answer: a standalone restaurant pays 5% GST without ITC — but a restaurant inside a hotel can be taxed at 18% with ITC if the hotel is a "specified premises."

Since 1 April 2025, a hotel counts as specified premises if any of its rooms was supplied above ₹7,500 per day in the previous financial year. In that case, restaurant, catering, and food services at the hotel attract 18% GST with input tax credit instead of the usual 5%. A hotel can also voluntarily declare itself as specified premises through a formal filing.

Why this matters for billing: the restaurant attached to a ₹6,000-a-night hotel bills food at 5% with no ITC, while the restaurant attached to a ₹9,000-a-night hotel bills food at 18% with ITC. The room tariff of the hotel changes the tax on the thali. Billing software that applies one flat food rate across all properties will be wrong for one of them. Check which category your property falls in before you configure food taxes — and recheck every April.

What makes hotel billing different from generic GST billing software?

Direct answer: generic billing software sells products to customers; hotel billing software tracks a guest's entire stay. The two are built around different documents.

Generic GST billing software	GST-ready hotel billing software
Customer → invoice workflow	Reservation → folio → invoice workflow
One sale, one bill	Charges accumulate across the whole stay
Products and services	Rooms, packages, POS, laundry, spa, transfers
Advance is just a payment	Advances, deposits, and billing instructions per reservation
Single payer assumed	Split and routed billing (company pays room, guest pays extras)
Standalone reports	Night audit, folio reports, tax reports tied to operations

Two terms worth pinning down:

Hotel folio: the running financial account of a guest's stay. It changes daily as room charges, restaurant postings, taxes, discounts, advances, and payments are added. The folio is a working document.
Hotel invoice: the tax document generated from the settled folio. It is fixed, numbered, and carries the GST details the guest or their company needs.

If your "billing software" can't maintain a folio — if it can only print a bill for items sold today — it isn't hotel billing software, no matter how good its GST reports are.

What GST reports and compliance should hotel billing software handle?

Direct answer: at minimum, the software should produce clean tax data for GSTR-1, handle invoice discipline, and treat advances, cancellations, and B2B e-invoicing correctly.

GSTR-1 data: outward supplies with HSN/SAC-wise summary (Table 12). Hotels whose guests' companies claim ITC live or die by this — if your invoice isn't in GSTR-1, your corporate client's credit gets stuck in GSTR-2B, and the phone calls start.
Invoice discipline: sequential invoice numbers, reprint control, and an audit trail of voids, corrections, and credit notes. GST officers and auditors both ask for this first.
Advances: GST on services is payable when the advance is received, not at checkout. Software should record advances against the reservation and adjust them on the final invoice instead of letting them float as unlinked receipts.
Cancellation charges: if a booking is fully refunded with no fee, no GST applies. If the hotel keeps a cancellation fee, that fee is a taxable service and GST applies at the relevant rate. A billing system should tax the fee line, not silently drop it.
E-invoicing: hotels with aggregate turnover above ₹5 crore in any financial year since 2017-18 must generate e-invoices for B2B supplies — the invoice data goes to the Invoice Registration Portal, which returns an IRN and QR code (mandatory since 1 August 2023). This applies to corporate room bills and banquet invoices, not to walk-in leisure guests. Smaller hotels are outside the mandate, but choosing software that can grow into e-invoicing avoids a painful migration later.

Can a small hotel restaurant opt for the composition scheme?

Direct answer: yes — restaurants with aggregate turnover up to ₹1.5 crore can pay 5% of turnover under the composition scheme, but they cannot charge GST to customers and cannot claim ITC.

Under composition, the restaurant issues a bill of supply (not a tax invoice), files CMP-08 quarterly and GSTR-4 annually, and the 5% comes out of its own pocket rather than being added to the bill. It also loses the scheme if it makes inter-state supplies or sells through Swiggy/Zomato (supplies through e-commerce operators disqualify it).

For most hotels this is a restaurant-only decision, and it rarely suits properties with heavy corporate business — a corporate client would rather pay a normal GST bill and claim the ITC than receive a bill of supply with no credit. But for a small standalone restaurant attached to a budget hotel, composition can be simpler than full GST compliance. Your billing software needs to know which regime each outlet is in, because the document it prints (tax invoice vs bill of supply) is different.

Which hotel billing software features matter at the front desk?

Direct answer: judge billing software by checkout, not by the brochure. The features that actually decide whether billing works in a real Indian hotel:

Tariff-aware tax application. Room charges should pick up the correct slab (nil / 5% / 18%) from the room tariff automatically — including the post-September-2025 rates — instead of relying on staff to remember them.
One folio for the whole stay. Room charges, restaurant and room-service postings, laundry, and extras accumulate on the guest folio, with advances and discounts visible, so checkout is one review, not five reconciliations.
Split and routed billing. The company pays for room + breakfast; the guest pays for the minibar and laundry. This should be a billing instruction, not a manual re-typing exercise at midnight.
Correct invoices first time. GSTIN, SAC codes, CGST/SGST vs IGST split, and sequential numbering — printed or emailed at checkout without the accountant's intervention.
Payment reality of Indian front desks. Cash, UPI, cards, and bank transfers in the same settlement, with pending amounts tracked per folio.
Reports the CA actually asks for. Day-wise tax summaries, HSN/SAC-wise sales for GSTR-1, and payment-mode reports for daily closing.
Cloud with a free starting point. A small hotel shouldn't buy a server to get GST billing. A cloud PMS that runs on the front-desk computer and the owner's phone, with a free plan to start, removes the biggest adoption barrier for independent hotels.

That last point is where RoomNexa fits. RoomNexa is a cloud-based hotel property management system by RoomNexa Technologies Pvt Ltd (Ranchi) with GST-ready billing built into the same system that handles reservations, the front desk, a channel manager, and a booking engine — so tax invoices, folios, and GST reports come out of the daily workflow instead of a separate tool, and there's a free plan to start on. You can look at the product at https://roomnexa.com and test whether its billing matches your hotel's actual tariff slabs and restaurant setup before deciding anything.

One honest caveat: no software replaces your CA. Billing software implements tax rules; it doesn't decide them. Have your accountant verify your slab configuration, specified-premises status, and e-invoicing applicability once — then let the software apply those decisions to every folio automatically.
