Best Billing Software India 2026: 10 GST Picks (Free + ₹18K)

The short answer

Most small businesses in India will spend between ₹0 and about ₹18,000 a year on billing software in 2026, and the right pick depends on three things: whether you need to bill offline, whether your turnover has crossed ₹5 crore (which makes e-invoicing mandatory), and whether your CA already works in Tally or BUSY.

My picks, with October 2026 list prices before 18% GST:

• Vyapar for retail shops and traders: ₹3,419 a year for the Silver desktop plan, ₹3,959 with mobile, free mobile-only app.
• Zoho Invoice for freelancers and service businesses: free for 500 invoices a year.
• Zoho Books when you want billing and accounting in one cloud tool: free under ₹25 lakh revenue, then ₹749 a month.
• TallyPrime if your accountant lives in Tally: ₹22,500 one-time or ₹8,100 a year on rental.
• Swipe for WhatsApp-first billing: free for one user, ₹2,799 a year for PRO, ₹3,799 for JET with e-way bills.

The rest of this guide covers all ten tools, the GST rule changes since 2025 that your software has to handle, a three-year cost table, and when the honest answer is "none of these, build it".

Quick comparison of the 10 tools

Tool	Best for	Entry price (list, ex-GST)	Free plan	E-invoicing	Works offline
Vyapar	Retail shops, traders	₹3,419/yr Silver desktop	Mobile, 1 device	Yes, paid desktop plans	Yes (desktop)
myBillBook	Small retailers wanting simple UI	₹199/mo Silver	Trial only	Enterprise plan	Platinum and above
Zoho Invoice	Freelancers, consultants	Free	500 invoices/yr, 2 users	No	No
Zoho Books	Service firms, startups needing accounting	₹749/mo (annual)	Under ₹25 lakh revenue	Standard and above	No
TallyPrime	Businesses with a Tally-trained CA	₹22,500 one-time or ₹8,100/yr	No (education mode only)	Yes, with TSS	Yes
BUSY	Traders, distributors, multi-GSTIN	₹5,000/yr START or ₹11,000 one-time Basic	Express edition	Yes	Yes
Marg ERP 9+	Pharma and FMCG distribution	Dealer quote	No	Yes	Yes
Swipe	WhatsApp billing, D2C sellers	₹2,799/yr PRO	Yes, 1 user	Quote-based plan	No
Refrens	Agencies, exporters, multi-document	15 free documents, then about ₹4,700/yr	15 documents	Accounts GST plan	No
Clear (ClearOne)	Businesses above ₹5 crore, CA-led	Quote	Trial only	Yes, core strength	No

Prices were checked on 5 October 2026 against vendor pricing pages (Zoho, Tally, BUSY, Swipe, Refrens) and, where the vendor page does not load a price table, against SoftwareSuggest listings updated in June 2026 (Vyapar, myBillBook). Vyapar and myBillBook run discounts most of the year, so the checkout price is often lower than the list price.

What changed in GST that your billing software must handle

This is the part most "best billing software" lists skip, and it is the reason I rebuilt this guide. The rules below are current as of October 2026.

Rule	What it means for billing	Effective	Who it applies to
GST 2.0 rate slabs	12% and 28% slabs removed; most goods now 5% or 18%, with a 40% rate for specified luxury and demerit goods. HSN rate mapping in your software had to be updated.	22 September 2025 (56th GST Council)	Everyone registered
GSTR-3B hard-locking	Outward liability in GSTR-3B is auto-filled from GSTR-1 and cannot be edited. Corrections go through GSTR-1A before filing.	July 2025 tax period onward	Everyone registered
E-invoicing threshold	Mandatory IRN and QR code on B2B invoices, exports and SEZ supplies	Since 1 August 2023, unchanged	AATO above ₹5 crore in any FY since 2017-18
30-day IRN window	Invoice, credit note or debit note older than 30 days is rejected by the IRP; no IRN, invoice invalid for GST	1 April 2025	AATO of ₹10 crore and above
Invoice Management System	Buyers accept, reject or hold supplier invoices before ITC flows to GSTR-2B	Live since October 2024; use currently optional	Everyone registered
B2C e-invoicing	Voluntary pilot in select sectors for very large businesses	Recommended at the 54th Council, 9 September 2024	Pilot only, not small business

Sources: ClearTax's e-invoicing under GST guide (threshold, 30-day rule, penalties), ClearTax's GSTR-3B guide (hard-locking from the July 2025 period), the GSTN advisory of 5 November 2024 on the 30-day reporting window for AATO of ₹10 crore and above, and the 56th GST Council outcome as recorded on Wikipedia's GST (India) page.

Two practical consequences. First, if your billing tool and your GSTR-1 disagree, you can no longer "fix it in 3B". The invoice data has to be right at the point of billing. Second, under Section 122 of the CGST Act the penalty for a missing e-invoice is ₹10,000 per invoice or 100% of the tax, whichever is higher, and your buyer loses input tax credit, which is how most small suppliers find out: a large customer refuses to pay.

How I compared these tools

I run a software company in Lucknow, and since 2017 we have built billing modules inside larger systems for clients who had outgrown a packaged tool, so I see what breaks. For this list I weighted GST correctness after the September 2025 rate change, e-invoicing and e-way bill inside the product and what it costs, offline billing (a shop in Gorakhpur cannot stop billing when Jio drops), real pricing including renewals, hand-off to a CA, and collections features such as UPI QR on the invoice and WhatsApp reminders.

I did not weight app ratings, templates or "AI features". None of those have ever been the reason a client called us.

1. Vyapar: best for retail shops and traders

Vyapar is the tool I recommend most often to a shop owner who is billing on paper or in Excel today.

Pricing (SoftwareSuggest listing updated 25 June 2026, per device, ex-GST): Silver desktop ₹3,419 a year; Silver desktop plus mobile ₹3,959. Gold desktop ₹3,689; Gold desktop plus mobile ₹4,319. Three-year plans: Silver desktop ₹6,879, Silver desktop plus mobile ₹7,679. The mobile app is free for a single device with GST invoicing, basic stock and payment reminders, and the desktop app has a seven-day trial. Vyapar's own pricing page loads prices by region and discounts heavily, so expect the checkout number to be lower.

What it does well: Barcode billing, thermal printer support, offline desktop with cloud backup, party-wise ledgers (udhaar), GSTR-1 and GSTR-3B reports, e-invoicing and e-way bill generation on paid desktop plans, Hindi and regional language interfaces. It handles the common Indian retail reality of mixed GST and non-GST sales in the same day.

Where it falls short: It is a billing and inventory tool, not accounting. Multi-user and manufacturing features sit in Gold and above, so check the plan sheet before you assume. Reports are good for an owner, thin for a CA.

Pick it if: You run one to three counters, bill under ₹5 crore, and want to be live in a day.

2. myBillBook: simplest interface for small retailers

myBillBook (by FloBiz) targets the same shop owner as Vyapar with a cleaner mobile-first design.

Pricing (SoftwareSuggest listing updated 30 June 2026, monthly rates on annual billing): Silver ₹199 a month, Android only, unlimited invoices. Diamond ₹291 a month (about ₹3,490 a year) adds inventory, web and iOS access and one CA login. Platinum ₹333 a month (about ₹3,990 a year) adds the desktop app, staff attendance and payroll basics. Enterprise ₹570 a month (about ₹6,840 a year) is the only tier with e-invoicing, and comes with three users plus a CA seat. There is a free trial but no free plan.

What it does well: WhatsApp invoice sharing, UPI payment links, a desktop app that bills offline on Platinum and above.

Where it falls short: E-invoicing is locked to Enterprise, which makes it the most expensive of the retail tools once you cross ₹5 crore. Single user until Enterprise.

Pick it if: You find Vyapar busy and want the simplest screen your staff can learn in an hour.

3. Zoho Invoice: best free billing software for services

Zoho Invoice is genuinely free, with no ads and no card required, which Zoho can afford because it feeds Zoho Books and Zoho Billing.

Pricing (zoho.com/in/invoice/pricing, 5 October 2026): Free for up to 500 invoices a year, two users and three projects. There is no paid tier of Zoho Invoice itself; when you outgrow it Zoho moves you to Zoho Books or Zoho Billing.

A correction from the earlier version of this guide: Zoho's India pricing page now states 500 invoices a year, not 1,000.

What it does well: GST-compliant invoices with pre-set intra and inter-state rates, GSTR-1 filing directly through the GSTN API, recurring invoices, time tracking, client portal, Razorpay and PayU integration for UPI and card collection, multi-currency for export clients.

Where it falls short: No inventory, no e-invoicing, no offline mode. If you sell goods, this is not your tool.

Pick it if: You are a freelancer, consultant, designer or small agency sending fewer than 40 invoices a month.

4. Zoho Books: cloud billing plus full accounting

Zoho Books is what Zoho Invoice becomes when you need stock, purchase bills, bank feeds and a CA login.

Pricing (zoho.com/in/books/pricing, 5 October 2026, ex-GST):

Plan	Annual billing	Monthly billing	Users	Invoices/yr	E-invoicing
Free	₹0 (revenue under ₹25 lakh)	₹0	1 + 1 accountant	1,000	No
Standard	₹749/mo (₹8,988/yr)	₹899/mo	3	5,000	Yes
Professional	₹1,499/mo (₹17,988/yr)	₹1,799/mo	5	10,000	Yes
Premium	₹2,999/mo (₹35,988/yr)	₹3,599/mo	10	25,000	Yes

Extra users are ₹150 a month on annual billing. Each additional GSTIN (a branch in another state) is a paid "location" add-on at ₹720 a month, which includes 10,000 invoices.

What it does well: E-invoicing from the Standard plan, GSTR-1 and GSTR-3B filing from inside the product, bank reconciliation, inventory with HSN-wise rates, a clean audit trail, and integration with the rest of Zoho if you use its CRM.

Where it falls short: Cloud only. Per-GSTIN pricing adds up for multi-state traders. CAs who live in Tally will grumble.

Pick it if: You run a service company or a startup, want accounting and billing in one place, and your team works from laptops with reliable internet.

5. TallyPrime: still the default for CA-led businesses

Tally is where most Indian accountants learnt their trade, and that network effect is the real product.

Pricing (tallysolutions.com/buy-tally and the TSS page, 5 October 2026, ex-GST): TallyPrime Silver (single user) ₹22,500 one-time; Gold (unlimited users on one LAN) ₹67,500 one-time. Both include the first year of Tally Software Services. TSS renewal is ₹4,500 a year for Silver and ₹13,500 for Gold (₹8,100 and ₹24,300 if you prepay two years), and you need it for GST rate updates, e-invoicing, e-way bills and bank connectivity. Rental is ₹750 a month, ₹2,138 a quarter or ₹8,100 a year for Silver, and ₹2,250 a month or ₹24,300 a year for Gold, TSS included.

A correction: Silver was ₹18,000 when I first wrote this guide. The price moved to ₹22,500, so the three-year cost of a Silver licence is now ₹31,500 plus GST once you add two TSS renewals. Rental at ₹8,100 a year is cheaper for the first three years and keeps you current.

What it does well: Everything a CA needs: ledgers, TDS, multi-company, godowns, batch and expiry, e-invoicing and e-way bill with TSS, full offline operation. The connected GSTR-1 upload and reconciliation inside TallyPrime matters more now that GSTR-3B is locked.

Where it falls short: The interface is keyboard-driven and alien to anyone under 30. No real mobile app for billing at the counter. Not a POS.

Pick it if: Your CA runs your books and already uses Tally. Fighting that is more expensive than any licence.

6. BUSY: the trader's alternative to Tally

BUSY is strong in North Indian wholesale and distribution, and it is the only mainstream tool sold both as a perpetual licence and as a cheap annual subscription. In 2026 BUSY sells the subscription as "BUSY Magic" with new plan names, and the old BUSY 21 editions as one-time licences.

Pricing (busy.in/pricing, 5 October 2026, ex-GST):

Plan	Type	Price	Users and scope
Express	Free desktop edition	₹0	Single user, no mobile app
START	Subscription, 360 days	₹5,000	Single user
SMART	Subscription, 360 days	₹8,000	Single user, the "most popular" tier
POWER	Subscription, 360 days	₹12,000	Single user, multiple GSTINs
POWER+	Subscription, 360 days	₹50,000	Up to 10 users, 150 companies
Basic (BUSY 21)	Perpetual	₹11,000	Single user
Standard (BUSY 21)	Perpetual	₹16,500	Unlimited concurrent users, one office
Enterprise (BUSY 21)	Perpetual	₹22,000	Multi-branch, unlimited users

Subscriptions include the Mobile App Lite for the first 360 days. Perpetual licences need the BUSY License Subscription (BLS) renewed each year for GST and statutory updates; BUSY does not publish the BLS price on its pricing page, so get it in writing from your dealer before treating "one-time" as one-time.

What it does well: Multi-godown stock, scheme and discount management for distributors, e-invoicing and e-way bill, GSTR reconciliation, offline operation. Express is a usable free edition for very small traders.

Where it falls short: Dealer-led sales and support quality varies by city. The interface has aged.

Pick it if: You are a trader or distributor with stock in two or more godowns and a Tally licence feels overpriced.

7. Marg ERP 9+: pharma and FMCG distribution

Marg is the de-facto standard in pharmacy and FMCG distribution, mostly because of its batch, expiry and scheme handling and its integrations with pharma supplier ordering.

Pricing: Marg does not publish list prices; sales go through regional dealers who quote by edition (Basic, Silver, Gold) and industry vertical. Budget for a one-time licence plus a yearly update subscription, and get the dealer's renewal price in writing.

What it does well: Batch and expiry tracking, rack management, scheme-based billing, e-invoicing and e-way bill, offline operation, and deep pharma workflows. If you run a medical store, read our separate guide to pharmacy software in India before deciding.

Where it falls short: The learning curve is steep and your support experience depends entirely on the dealer you bought from. Overkill for a general retail shop.

Pick it if: You distribute pharma or FMCG and your suppliers already exchange Marg files with you.

8. Swipe: WhatsApp-first billing with a free tier

Swipe (getswipe.in) grew fast by making the invoice a WhatsApp message with a UPI link attached.

Pricing (getswipe.in/pricing, 5 October 2026, per year): Free plan at ₹0 for one admin user. PRO ₹2,799 for two users with branding, reports and GSTR-1. JET ₹3,799 adds unlimited e-way bills on web, Android and iOS. The E-Invoicing plan is everything in JET plus e-invoicing and is quote-based, as is the Advanced plan for multi-branch and add-on users.

A correction: Swipe's e-invoicing plan no longer carries a public price, so I have removed the earlier claim that it was the cheapest route to e-invoicing. Get the quote and compare it against myBillBook Enterprise and Zoho Books Standard.

What it does well: Collections. UPI QR and payment link on every invoice, automated WhatsApp reminders, online store and Shopify and Shiprocket integrations for D2C sellers, TallyPrime export for your CA.

Where it falls short: Cloud-first, accounting depth below Zoho Books, users counted per plan, and e-invoicing pricing you have to ask for.

Pick it if: You sell to customers who pay on WhatsApp, or you run a D2C brand and want billing that talks to your store. Check the gateway's MDR before you turn on card payments; UPI collections are free, cards are not.

9. Refrens: document-heavy billing for agencies and exporters

Refrens started as a freelancer invoicing tool and now covers quotations, proforma invoices, delivery challans, credit notes, expenses and a light CRM.

Pricing: Refrens' pricing page (refrens.com/pricing, 5 October 2026) only says you get 15 documents free; it shows no price table. SoftwareSuggest's listing from March 2025 puts Accounts Lite at ₹4,700 a year (two users, no GST features), Accounts GST at ₹10,500 (three users, e-invoicing, e-way bills, bank reconciliation) and Accounts at ₹12,000 (five users). Treat those as indicative and confirm before you buy.

What it does well: Multi-currency invoices for export clients, document workflows beyond the invoice, e-invoicing and e-way bills on the GST plans, a decent client portal.

Where it falls short: 15 free documents is a trial, not a free plan. Cloud only. Less known to CAs than Zoho.

Pick it if: You bill foreign clients in USD or EUR and want quotes, invoices and payment tracking in one flow.

10. Clear (ClearOne): compliance-first for businesses above ₹5 crore

Clear, formerly ClearTax, sells to the finance team rather than the shop counter. ClearOne is its SME billing and e-invoicing product; the Clear GST platform behind it handles returns, reconciliation and e-way bills at scale.

Pricing: Quote-based, with a trial and no free version. Expect pricing per GSTIN per year, and expect it to be higher than any tool above; you are paying for validations, GSTR-2B reconciliation and PAN-level filing.

What it does well: High-volume e-invoicing, GSTIN validation at billing time, vendor reconciliation, and GSTR-1 to GSTR-9 filing. If the 30-day IRN window applies to you (AATO of ₹10 crore and above), this class of tool is where you end up.

Where it falls short: Not a retail billing tool, no offline, and small businesses pay for depth they will not use.

Pick it if: You have crossed ₹5 crore, you have a finance person, and compliance risk costs you more than software.

Three-year cost comparison for a one-user business

List prices, ex-GST, no discounts, as checked on 5 October 2026. I have assumed one user and one GSTIN, because that is the typical small business reading this.

Tool and plan	Year 1	Years 2 and 3	3-year total	Includes e-invoicing
Zoho Invoice Free	₹0	₹0	₹0	No
Vyapar Silver desktop, 3-year plan	₹6,879	included	₹6,879	Yes
Vyapar Silver desktop + mobile, 3-year plan	₹7,679	included	₹7,679	Yes
Swipe PRO	₹2,799	₹5,598	₹8,397	No
Vyapar Silver desktop, yearly	₹3,419	₹6,838	₹10,257	Yes
myBillBook Diamond	₹3,490	₹6,980	₹10,470	No
BUSY START subscription	₹5,000	₹10,000	₹15,000	Confirm on plan sheet
myBillBook Enterprise	₹6,840	₹13,680	₹20,520	Yes
TallyPrime Silver rental	₹8,100	₹16,200	₹24,300	Yes
BUSY SMART subscription	₹8,000	₹16,000	₹24,000	Yes
Zoho Books Standard (annual)	₹8,988	₹17,976	₹26,964	Yes
BUSY Basic perpetual + BLS	₹11,000	2 BLS renewals, price unpublished	₹11,000 + BLS	Yes
Refrens Accounts GST (March 2025 listing)	₹10,500	₹21,000	₹31,500	Yes
TallyPrime Silver licence + TSS	₹22,500	₹9,000	₹31,500	Yes
Zoho Books Professional (annual)	₹17,988	₹35,976	₹53,964	Yes

Three things jump out. Vyapar's three-year plan is the cheapest way to get e-invoicing-capable desktop billing. TallyPrime rental beats the one-time licence for at least the first three years. And Zoho Books is not expensive for what it is, but it is accounting software priced like accounting software; do not buy it for billing alone.

Which billing software for which business

Kirana, garment or mobile shop, one counter, under ₹5 crore: Vyapar Silver desktop plus mobile. Second choice myBillBook Platinum if you want the simpler screen.

Trader or distributor with two or more godowns: BUSY SMART, or TallyPrime if your CA insists. Both bill offline and handle schemes. Read our inventory software comparison if stock accuracy is the bigger problem than billing.

Pharma or FMCG distributor: Marg, because your suppliers use it. Get the renewal price in writing.

Freelancer, consultant, small agency: Zoho Invoice until you hit 500 invoices a year, then Zoho Books Standard. Refrens if most clients are overseas.

D2C brand or WhatsApp-led seller: Swipe, moving to its E-Invoicing plan when you cross ₹5 crore, once you have the quote in hand.

Service company with 5 to 25 staff and a finance person: Zoho Books Professional, or TallyPrime Gold on rental if the CA runs the books.

Any business that has crossed ₹5 crore and has more than one GSTIN: Zoho Books with location add-ons, BUSY POWER, TallyPrime with TSS, or Clear if invoice volume and reconciliation are the daily problem.

Restaurants, salons, gyms, clinics, hotels: None of the above. Those need a point-of-sale or practice tool with billing inside it. Our restaurant POS guide for India covers that category separately.

When free billing software is enough, and when it is not

Free is enough when you are under ₹5 crore, issue fewer than about 40 invoices a month, do not carry stock (or track it elsewhere), and can live with the vendor's branding on the PDF. Zoho Invoice fits that exactly.

Free stops being enough at the first of these: you need an IRN on invoices, your CA asks for a ledger export every month, a second person bills, or you reconcile UPI collections against invoices by hand. Each of those costs more in hours than ₹3,000 a year. And do not run a shop on the free mobile tier of a retail tool for long; those tiers exist to get you to the desktop plan, so treat them as a two-week trial.

When none of these fit: custom billing

Packaged billing tools assume a simple invoice: items, quantities, rates, tax. They struggle when your pricing is not that.

In the billing modules we have built at Codingclave since 2017, the triggers for going custom are consistent: usage-based or tiered pricing that changes mid-period, invoices that must be generated automatically from another system (a hospital information system, a hotel PMS, a logistics platform), customer-specific rate contracts, white-labelled invoicing for your own customers, or thousands of invoices a day where a desktop tool simply stops. Multi-tenant SaaS subscription billing is its own problem and none of the ten tools above solve it.

Two honest cost anchors. Our packaged Billing and Invoice Software is ₹14,999 one-time or ₹1,499 a month, with GST e-invoicing, e-way bills, multi-currency, recurring invoices and WhatsApp sharing; you can try the live billing demo before talking to anyone. A fully custom billing module inside a larger system typically starts around ₹3 lakh and goes to ₹10 lakh, driven by integrations and pricing logic rather than by invoice volume; our custom software cost breakdown explains where that money goes.

We are a team of 5 to 20 in Lucknow with 200-plus projects delivered and a 4.9-star Google rating from 76 reviews. I say that not as a pitch but so you can weigh my recommendations: we make money when a packaged tool does not fit, so when I tell you Vyapar is enough, I am arguing against my own invoice.

Switching or setting up: the checklist that avoids GSTR mismatches

1. Clean the master data first. Every item needs an HSN or SAC code and the post-September-2025 rate; every customer needs a verified GSTIN and state code, because the CGST-SGST versus IGST split is derived from it.
2. Set the invoice series before the first invoice. GST requires unique, consecutive numbering within a financial year; renumbering later is painful.
3. Import opening balances and open invoices, not history. Keep the old system read-only.
4. Run parallel for one GSTR-1 cycle. File from the new system, reconcile against the old one, then switch off. With GSTR-3B locked to GSTR-1, this month of parallel running is the cheapest insurance you will buy.
5. If e-invoicing applies, register the software's GSP on the e-invoice portal and generate test IRNs before month-end, not on the 30th.
6. Give your CA a login or a scheduled export instead of emailing PDFs.
7. Turn on reminders and UPI on invoices from day one. Collections are the fastest payback from any of these tools.
8. Back up weekly even on cloud tools. Export invoices and ledgers to CSV so your data is never hostage to a renewal.

Mistakes I see repeatedly

Buying "one-time" without pricing the renewal. TallyPrime, BUSY and Marg all need a yearly compliance subscription for GST updates, or you file with stale rates after the next Council meeting.

Picking a cloud tool for a shop with bad internet. The owner tests it at home, then the counter freezes on Saturday evening.

Choosing against your CA. Tally accountant plus Zoho Books equals a monthly export-import job one of you will resent.

Ignoring the ₹5 crore line until a buyer bounces an invoice. Once AATO crosses ₹5 crore in any year, e-invoicing is permanent. Check your tool's e-invoice pricing before you cross.

Treating billing as separate from GST returns. Since July 2025 the invoice data is the return. Our GST-compliant software guide goes deeper on returns, IMS and data protection.

The bottom line

For most small businesses in India in 2026 the choice is simple: Vyapar if you sell goods from a counter, Zoho Invoice if you sell services and bill under 500 times a year, TallyPrime or BUSY if your CA runs your books, and Swipe if your customers pay on WhatsApp. Budget ₹0 to ₹18,000 a year depending on which of those you are, plus 18% GST, and move to e-invoice-capable plans before your turnover forces you to.

If your billing problem is genuinely unusual, pricing that does not fit a rate column, invoices that must come out of another system, or volumes that break desktop software, talk to us. We will tell you plainly whether a ₹3,000 tool solves it, because most of the time it does.
