Sales tax and VAT software for BUSY
BUSY prepares GSTR-1 and GSTR-3B, generates IRNs against the IRP, and validates a GSTIN in one click. India is the only tax regime it covers. Sell to a customer in the United States or the EU and that obligation sits outside your books. Commenda registers you, tracks the thresholds, and files across all 50 states and 70+ countries.
Trusted by global businesses
Monitor your exposure outside India
BUSY reports against the GSTINs on your company. Commenda measures the same sales against economic and physical thresholds in all 50 US states and 70+ countries, and notifies you at 80% of a registration threshold.
Tax the export invoices BUSY zero-rates
A supply under LUT or bond, or to an SEZ unit, carries no Indian GST. The US state or EU country your buyer sits in can still want its own tax on that sale. Commenda calculates and collects it.
Register and file outside India
BUSY's return formats are GSTR-1, GSTR-3B, GSTR-4 and GSTR-9, all Indian. Commenda registers you and files across all 50 states, the EU with OSS and IOSS, and GST in APAC and Canada.
Coverage comparison
What BUSY covers, and where it stops at the border
BUSY does substantial India GST work, so the first row goes its way and the second is split. Its figures come from BUSY's own pages on GST accounting, e-invoicing, features, direct GST upload, and SEZ supplies, checked on July 30, 2026.

Calculate taxes globally on BUSY using Commenda
BUSY applies the CGST, SGST or IGST split from the place of supply, with HSN and SAC codes on the line. On an export it applies nothing, because the supply is zero-rated. Commenda calculates the destination tax on that same transaction: state, county, city and district for a US sale, and the right VAT rate for an EU one. Taxability is applied per jurisdiction, per product.

Track your global exposure from BUSY
BUSY keeps separate records per GST registration, which is the right shape for an Indian distributor with branches in several states. Foreign exposure works on a different axis. Commenda measures your transactions against thresholds in all 50 states, every EU member state, and 70+ countries. A short questionnaire covers physical presence, because a warehouse or a contractor never shows on a sales voucher.

Automatically remit transactions around the world
In BUSY the last step is always on the GST portal, whether you exported the JSON or used direct upload. Commenda builds the foreign return from your data and submits it, so nobody is logging into a government site at month end. Returns go out across all 50 states, EU VAT with OSS and IOSS, and GST in APAC and Canada, with amendments where a period needs correcting.

Manage your customers and exemptions in one place
BUSY offers one-click GSTIN and HSN validation against the portal, which settles your Indian customer master. An EU VAT number and a US resale certificate are different documents on a different register. Commenda validates the tax ID on the customer record, collects exemption certificates through a portal your customers upload to, and applies each one automatically where it is valid.

Consolidation
Why BUSY cannot see your foreign exposure
BUSY covers the Indian job well. The gap opens the moment a sale leaves the country, because an export drops out of your books as a zero-rated line and picks up an obligation no GSTR captures. Commenda covers that side.
BUSY moves the return, the portal files it
BUSY documents two routes. Download the GSTR JSON and upload it yourself, or use direct upload on the standard and enterprise models with API access enabled for 30 days on the portal. Both end with a submission on the GST portal. That is worth knowing before you compare it to anything else, because uploading data and filing a return are different amounts of work.
Zero-rated in India says nothing about the destination
A supply under LUT or bond, or to an SEZ unit, leaves India with no IGST. Correct in India, and silent about Texas or Germany. Once you pass a state's economic nexus threshold you owe tax there at a combined rate you can look up in our sales tax rate calculator, with no Indian return capturing it.
Your books sit on a Windows PC in the office
BUSY's system requirements are Windows 7 or later with .NET Framework 3.5 or above, and an internet connection for activation and for the e-way bill and e-invoice features. There is no cloud instance to point at. We plan the extract, the fields, and the cadence during setup, and it runs from your data with no engineering work on your side.
One ledger behind every branch and every channel
A distributor's sales rarely all originate in one place. A marketplace, a payment gateway, and a branch on its own GSTIN each produce revenue that counts toward a foreign threshold. Every source connects to one ledger, across 100+ supported integrations. Each transaction carries its origin, its product tax code, and any tax already collected, so you get one exposure figure per jurisdiction and one return per period.

Frequently asked questions
It gets the data there and the portal completes the filing. BUSY documents two routes. You can export the JSON from the GSTR-1 or GSTR-3B screen and upload it on the GST portal yourself. Or you can use direct upload, which BUSY limits to the standard and enterprise models and which needs your GST portal username configured under Administration plus Manage API access enabled for 30 days on the portal, confirmed by OTP. Either way BUSY's own step list ends with uploading to the portal and submitting the return there, and it documents no DSC or EVC inside the software.
Smart or above. BUSY's Start plan at ₹5,000 per 360 days covers billing, inventory, and the financial statements, with no e-invoice or e-way bill. Smart at ₹8,000 per 360 days is where the GSTR-1 and IFF dashboard, GST reconciliation, and an allowance of up to 10,000 e-way bills and e-invoices begin. Power at ₹12,000 raises that to 20,000 and lets you manage multiple GSTINs in one company. Power+ at ₹50,000 covers ten users, 150 companies, and up to 50,000. Worth checking against your invoice volume before you renew.
No. BUSY's tax engine is Indian GST, so a sale to a foreign customer is recorded as a zero-rated export and no destination tax is calculated. Its return formats are GSTR-1, GSTR-3B, GSTR-4 and GSTR-9. Commenda calculates the US or EU tax on the same transaction, registers you where you have crossed a threshold, and files across all 50 states, the EU with OSS and IOSS, and GST in APAC and Canada.
For the Indian side, yes. BUSY handles SEZ entries, keeps a record of your LUTs and bonds, and reports the supply as zero-rated in your GST returns. That covers your Indian filing position and your refund claim on accumulated input tax credit. It does not touch the buyer's country. If the same goods or services go to a customer in the United States or the EU rather than an SEZ, the destination may want its own tax on the sale, and Commenda is what handles that side.
Yes. Commenda registers you for GST in India and files GSTR-1 and GSTR-3B on your return frequency, built from the same sales data BUSY already holds. Your entity records sit alongside it: GSTIN, PAN and TAN are kept updated by our team, with your registrations and licences by jurisdiction, and we incorporate in India. The same connection covers the tax you owe outside India, so one platform handles both sides.
We plan for that rather than around it. BUSY lists Windows 7 or later, an Intel Core i3 or equivalent, 4 GB of RAM, and .NET Framework 3.5 or above, so the data sits on your own hardware and there is no cloud instance to connect to. In practice the handoff is the one Indian finance teams already run for their auditors: agreed exports of transactions and trial balances on an agreed cadence. Raw software exports are fine rather than formatted statements. No engineering work on your side.
Yes, on both sides. BUSY manages multiple GSTINs in one company from the Power plan up, and keeps separate records per registration. Commenda reads all of them and keeps the exposure separate where it needs to be separate. Foreign registrations work the same way: each has its own thresholds, its own return, and its own filing frequency, and you switch between entities on one dashboard rather than running a tool per country.
No, because its reports are organised around the GSTINs on your company. Its GSTR-2A and GSTR-2B reconciliation matches your purchase records against what your suppliers filed, which is a check on registrations you already hold. A state or country you have sold into for two years without registering produces no row anywhere in BUSY. Commenda measures the transactions instead, against economic and physical thresholds in all 50 states and 70+ countries, and notifies you at 80% of a registration threshold.
Custom integration support for your business
Every BUSY setup is configured differently, and it sits on your own hardware rather than in the cloud. We map how yours works, including your branches and their GSTINs, agree the export and the cadence, and build the integration to match.
Indirect Tax
Monitor nexus exposure, register, file, and remit sales tax and VAT in one platform. Commenda keeps you compliant across 100+ jurisdictions.
