Excellon has been delivering robust GST return filing solutions since 2016. Today, we process e-Invoices and e-Way bills for major enterprises across India, guaranteeing 99.7% uptime and enterprise-grade security as a trusted GSP.

We provide highly secure, scalable RESTful APIs and web services for seamless e-Invoicing, e-Way Bill generation, and end-to-end GST compliance.

Our core offerings include EXACT PASS (Pass-through APIs, both with and without Excellon-handled encryption), EXACT EWB, EXACT e-Invoice, and the comprehensive EXACT Suite (our full ASP-GSP application).

No. While we are proudly SAP-certified, our RESTful APIs are completely platform-agnostic and can be seamlessly consumed by any front-end solution, including Oracle, Microsoft Dynamics, custom ERPs, and legacy systems.

Our APIs are fully deployed and running. Once your technical team develops the front-end consumption logic or utilizes our pre-built connectors, you can start generating e-Invoices almost immediately.

Absolutely. We provide comprehensive API documentation, JSON schemas, and dedicated technical guidance to your team to ensure a smooth and rapid integration process.

To ensure maximum security and proper configuration, all account creations, API user portal setups, and initial login credentials are handled directly by our dedicated onboarding team during your setup phase.

We operate on a transparent billing model. We charge based on the total number of invoices generated, not per individual API call.

No, we do not charge separately for standard government regulatory API updates, unless your business requests a highly specific custom development requirement.

We offer dedicated 24x7 Non-IVR support, ensuring you bypass automated menus and connect directly with an expert when you need critical assistance.

Typically, PDFs are not generated in the PASS (API) solution as we do not store your data. However, our EXACT Suite solution offers PDF and Excel exports. For PASS users, PDFs can be retrieved directly from the government E-invoice portal within 2 days of invoice creation.

Because Excellon EXACT operates as a highly secure pass-through solution, we do not store your invoice data. Any required deletions or cancellations must be managed directly through your ERP or the government E-Invoice portal within the permitted legal timeframe.

Yes. All data is encrypted end-to-end using bank-grade security protocols. Our pass-through architecture ensures your sensitive financial and compliance data is never stored on our servers.
