Continuous supply of services — such as annual maintenance contracts, software subscriptions, and long-term consultancy agreements — has special invoicing requirements under GST. This article provides a comprehensive guide.
What Is Continuous Supply of Services?
Continuous supply of services means a supply of services where:
- The supply is provided continuously or on a recurring basis
- The contract provides for periodic payments
- The supply is covered by a contract
Examples:
- Annual maintenance contracts (AMC)
- Software subscriptions (SaaS)
- Consultancy retainers
- Insurance services
- Telecom services
- Banking services
Legal Framework
Time of Supply for Continuous Services
The time of supply for continuous supply of services is:
- The date of payment (if payment is made before invoice)
- The date of invoice (if invoice is issued before payment)
- The date of completion of the service (if neither payment nor invoice)
Invoicing for Continuous Services
For continuous supply of services, the supplier must issue an invoice:
- Before or at the time of payment (if payment is due)
- Within 30 days of the completion of the service (if no payment is made)
Invoicing Requirements
When to Issue Invoice
Scenario 1: Payment Due If payment is due on a specific date, the invoice must be issued before or at the time of payment.
Scenario 2: No Payment Due If no payment is due, the invoice must be issued within 30 days of the completion of the service.
Contents of Invoice
The invoice must contain all mandatory particulars, including:
- Description of the continuous service
- Period of service
- Payment schedule (if applicable)
Special Considerations
Annual Maintenance Contracts (AMC)

- Or at each payment milestone
- GST is payable on each invoice
Software Subscriptions (SaaS)
- Invoice is typically issued monthly or annually
- GST is payable on each invoice
- The place of supply rules apply
Consultancy Retainers
- Invoice is typically issued monthly
- GST is payable on each invoice
Telecom and Banking Services
- Special rules apply for telecom and banking services
- Invoice may be issued within 45 days for banking/insurance/NBFC
Practical Examples
Example 1: Annual Maintenance Contract
Facts: A company enters into an AMC for ₹1,20,000 per year. Payment is due annually in advance.
Action: Invoice issued at the start of the year for ₹1,20,000 + GST. GST paid on the full amount.
Example 2: Monthly SaaS Subscription
Facts: A company subscribes to a SaaS service at ₹10,000 per month.
Action: Invoice issued monthly for ₹10,000 + GST. GST paid monthly.
Example 3: Consultancy Retainer
Facts: A consultant provides services on a retainer basis at ₹50,000 per month.
Action: Invoice issued monthly for ₹50,000 + GST. GST paid monthly.
Common Errors
Error 1: Delayed Invoicing For continuous services, invoices must be issued on time.
Error 2: Incorrect Period Mention The invoice should mention the period of service.
Error 3: Wrong Time of Supply The time of supply determines the tax rate and due date.
Error 4: Not Following Payment Schedule Invoice issuance should align with the payment schedule.
