Most GST software is a filing tool bolted onto a separate accounting product. Aczen is one system — your books, GST, payments and banking live together, so reconciliation is real-time.
Recover every rupee of ITC
Aczen's GSTR-2B reconciliation flags missing supplier filings, value mismatches and GSTIN errors before the 20th. Most teams discover 2–5% additional ITC in the first month.
Never miss a deadline
GSTR-1, GSTR-3B, GSTR-9, TDS due dates, ROC filings — Aczen tracks every deadline for every GSTIN and sends escalating alerts so nothing slips.
Real-time e-invoicing
IRN, QR code and signed JSON are generated at the moment of invoice creation — not in a batch job at end-of-day. Cancel and amend within the GSTN-allowed windows.
Audit-ready always
Every change is logged with user, timestamp and field-level diff. Department audits and due-diligence requests take hours instead of weeks.
Frequently asked questions
Everything you wanted to know about Aczen GST compliance software.
What is GST compliance software?+
GST compliance software is a tool that helps Indian businesses generate GST-compliant invoices, file GST returns (GSTR-1, GSTR-3B, GSTR-9), reconcile input tax credit against GSTR-2B, and meet e-invoicing and e-way bill obligations. Aczen does all of this from a single dashboard.
Can Aczen file GST returns directly to the GSTN portal?+
Yes. Aczen is a GSP-integrated platform — once your return is prepared, you can file it to the GSTN portal with a single click using OTP or DSC. No JSON uploads or manual copy-paste.
Does Aczen support e-invoicing for businesses above the Rs. 5 crore turnover threshold?+
Yes. Aczen automatically generates IRN-validated e-invoices for every B2B sale, attaches the QR code, and submits to the IRP in real time. The threshold has been progressively reduced — Aczen handles the latest CBIC limits.
How does GSTR-2B reconciliation work in Aczen?+
Aczen pulls your GSTR-2B from the GSTN portal and automatically matches it against your purchase ledger. Mismatches are categorised — missing in 2B, missing in books, value mismatch, GSTIN mismatch — so your team can take targeted action and never lose ITC.
Is Aczen suitable for chartered accountants managing multiple clients?+
Yes. Aczen is widely used by CAs to manage 100+ client GSTINs from a single login. White-label invoicing, consolidated dashboards, bulk return filing and client-level audit trails are all built in.
What happens if I file a return late or with errors?+
Aczen flags errors before submission and shows you the exact field that's invalid. If a return has already been filed, you can amend it through the standard GST amendment workflows directly from the platform.
