A GST invoice template designed for IT companies, software developers, and tech service providers serving Indian clients.
The Indian IT services sector has unique invoicing requirements under GST that this template addresses comprehensively. IT services span a wide range of SAC codes: 998314 for IT consulting, 998315 for IT support and infrastructure, 998316 for hosting and infrastructure services, 998317 for IT design and development, and 998318 for software licensing. This template handles all these scenarios with appropriate code mappings. A critical feature for IT companies is the treatment of export of services, which is zero-rated under GST when provided to clients outside India. The template includes fields for LUT (Letter of Undertaking) reference number and export declaration, enabling IT companies to invoice foreign clients without charging IGST. For domestic billing, the template supports both time-and-material contracts (hourly/daily rates with timesheet reference) and fixed-price projects with milestone billing. It also handles the common SaaS billing model with recurring invoice generation fields. The template accounts for reverse charge mechanism when IT companies procure services from foreign vendors, showing the GST liability on the recipient.
This template is built for IT service companies, software development firms, web development agencies, app development studios, IT consulting practices, managed service providers (MSPs), SaaS companies billing Indian customers, cloud hosting providers, and any technology company registered under GST. It is especially valuable for companies that serve both domestic and international clients and need to handle different GST treatments.
Step 1: Enter your company details including GSTIN and company registration number. Step 2: Select the appropriate SAC code for your service. Step 3: For domestic clients, choose CGST+SGST (same state) or IGST (different state). Step 4: For international clients, enter your LUT reference number and mark as zero-rated export. Step 5: For time-and-material projects, enter hours/days worked, rate, and reference the timesheet/sprint number. Step 6: For fixed-price milestones, list each deliverable and its billing amount. Step 7: Add SaaS subscription details if applicable (billing period, plan name). Step 8: Include payment instructions.
IT services attract 18% GST under the relevant SAC codes (9983 series). Export of IT services is zero-rated under Section 16 of the IGST Act - either pay IGST and claim refund, or export under LUT/bond without IGST payment. For reverse charge on imported services (e.g., cloud services from AWS/Azure), the Indian company must self-assess and pay GST. E-invoicing mandatory for turnover above Rs 5 crore. Software supplied electronically is treated as service (not goods) under GST.
