Frequently Asked Questions

Everything you need to know about BUSY Accounting Software and our support services.

Can BUSY file GST returns directly to the GST portal?
BUSY supports GST return preparation and workflows including GSTR-1/IFF upload, JSON-based return files, and return dashboards depending on the edition. It keeps books and GST data consistent so filing is faster and more accurate. Contact us to find the right edition for your business.
How does BUSY help with ITC reconciliation?
BUSY compares your purchase records with GSTR-2A and GSTR-2B data in relevant editions. It highlights mismatches — missing invoices, supplier filing delays, or value differences — so you can review and correct ITC before finalising returns.
What is the difference between GSTR-1 and GSTR-3B in BUSY?
GSTR-1 contains outward supply details (your sales invoices), while GSTR-3B is a monthly summary return for tax liability and input tax credit. BUSY prepares both using the same accounting data — eliminating duplicate entry and keeping books consistent with return data.
Does BUSY support e-invoicing and e-way bill?
Yes. BUSY supports e-invoicing workflows including IRN generation and QR code functionality in relevant editions. E-way bill generation and management is also supported. This removes the need to manage these processes separately from your accounting.
Is BUSY suitable for Chartered Accountants managing multiple clients?
Yes. BUSY supports multi-company and multi-GSTIN workflows, making it ideal for CAs and tax practitioners managing accounting and GST compliance for multiple clients from one single platform.
Which BUSY edition is right for my business?
BUSY offers Express Mazu, Blue, Saffron, and Emerald editions. From basic billing to advanced GST reconciliation, e-invoicing, multi-branch, and MIS reports — there is an edition for every business size. Call us at +91-82707 90690 and we will recommend the best fit.
How do I migrate from Tally to BUSY?
Kavin Marketing handles complete migration from Tally or Excel to BUSY — including ledgers, stock masters, opening balances, and historical voucher data. Our team ensures zero data loss and validates everything before handover.
What areas does Kavin Marketing serve?
Head office is in Vaniyambadi. We provide remote support PAN India and on-site support across Tamil Nadu. Call +91-82707 90690 or email kavinmarketing88@gmail.com.
