Use this page when you need to produce an invoice for work sold to a customer in India, especially services billed by project, task, milestone, or time period. The finished document should show who supplied the work, who received it, what was supplied, the taxable value, the GST treatment, the invoice date, and the payment terms.
For GST-registered suppliers, the invoice is also a tax record. India uses Goods and Services Tax, with CGST plus SGST or UTGST generally applying to intra-state supplies and IGST applying to inter-state supplies. That split matters because the wrong tax type can create correction work for both supplier and buyer.
A GST tax invoice issued by a registered supplier must show the supplier's name, address, and GSTIN. For a registered recipient, include the recipient's name, address, and GSTIN or UIN. For an unregistered recipient, name, address, delivery address, state, and state code are required when the taxable supply value is at least Rs. 50,000.
Each invoice line should identify the HSN code for goods or accounting code for services, describe the goods or services, and show quantity for goods, total value, taxable value, and any discount or abatement. The invoice must show the GST rate and amount by tax type, including central tax, state tax, integrated tax, Union territory tax, or cess where applicable.
The invoice serial number must be consecutive, unique for the financial year, and no longer than 16 characters. It may contain letters, numbers, a hyphen, a dash, or a slash. A GST tax invoice must also include its date of issue, and service invoices are generally required within 30 days from the date of supply of service unless a special category applies.
For inter-state supplies, the tax invoice must state the place of supply with the state name. It must also show the delivery address when it differs from the place of supply. GST e-invoicing applies to notified B2B taxpayers whose aggregate turnover exceeded Rs. 5 crore in any financial year from 2017-18 onward, with covered invoices reported to the Invoice Registration Portal for an IRN and signed QR code.
A one-off invoice is enough when you need a clean document for a single job, a simple service sale, or a client who already gave you the correct GSTIN and billing address. It also works when you can verify the GST breakup, place of supply, invoice number sequence, and payment term before sending.
A managed workflow becomes necessary when billable time, expenses, project rates, tax treatment, approvals, and client reporting all need to stay connected. Everhour Reporting provides customizable reports with 45+ columns, filters, grouping, exports, and scheduled email delivery, so teams can review billable work and invoice status before accounting handoff.

A GST tax invoice from a registered supplier must show the supplier's name, address, and GSTIN, plus the invoice number and date of issue. It also needs recipient details, supply description, HSN or SAC, taxable value, GST rate, and GST amount broken out by the applicable tax type.
Use CGST plus SGST or UTGST for intra-state supplies, and use IGST for inter-state supplies. The place of supply decides the tax treatment, so an inter-state invoice must state the place of supply with the state name. A wrong split creates GST reporting and reconciliation problems.
GST e-invoicing applies to notified B2B taxpayers whose aggregate turnover exceeded Rs. 5 crore in any financial year from 2017-18 onward. Covered invoices are reported to the Invoice Registration Portal, which returns an IRN and signed QR code. Smaller suppliers outside the notified scope still need valid GST invoice fields.
The serial number must be consecutive and unique for the financial year. It can contain letters, numbers, a hyphen, a dash, or a slash, but it must stay within 16 characters. Reusing a number or changing the sequence without a clear record creates avoidable audit and bookkeeping issues.
When the supplier is a micro or small enterprise covered by the MSMED Act, the agreed payment date cannot exceed 45 days from acceptance or deemed acceptance. Delayed payment has interest consequences, so the invoice due date should match the contract and stay inside that statutory outer limit.
Everhour Reporting lets teams build reports with 45+ columns, grouping, filters, date ranges, and exports in CSV, Excel/XLSX, or PDF. A billing lead can review billable time, invoice status, costs, revenue, and project data before preparing or reconciling client invoices.
