Use this page when you need a clean invoice for work supplied in India, especially services, project work, consulting, development, agency retainers, or billable expenses. A GST invoice from a registered supplier needs more than a client name and total. It must carry the supplier's GSTIN, invoice number, issue date, recipient details, line-item codes, taxable value, tax amounts, and supply details where applicable.
The goal is a document that your client can read, approve, and process without asking for missing tax data. That means each line should connect the work performed to an HSN code for goods or accounting code for services, commonly called SAC. The invoice should also separate commercial terms from statutory tax fields so the buyer can verify the charge and account for GST correctly.
A GST tax invoice issued by a registered supplier must show the supplier's name, address, and Goods and Services Tax Identification Number. The serial number must be consecutive and unique for the financial year, and it can use letters, numbers, hyphen, dash, or slash within a limit of up to 16 characters. Service invoices are generally required within 30 days from the date of supply of service unless a special category applies.
Recipient details depend on the buyer. For a registered recipient, include the recipient's name, address, and GSTIN or UIN. For an unregistered recipient, include name, address, delivery address, state, and state code when the taxable supply value is at least Rs. 50,000. Line items should show description, HSN or SAC, quantity for goods, total value, taxable value, and any discount or abatement that changes the taxable amount.
India uses Goods and Services Tax on supplies of goods and services. CGST plus SGST or UTGST generally applies to intra-state supplies, while IGST applies to inter-state supplies. The invoice must show the GST rate and amount charged by tax type, including central tax, state tax, integrated tax, Union territory tax, or cess as applicable. It must also state reverse-charge status where relevant.
Inter-state supplies need extra location detail. The tax invoice must state the place of supply along with the name of the state, and it must state the delivery address when it differs from the place of supply. GST e-invoicing applies to notified B2B taxpayers with more than Rs. 5 crore aggregate turnover in any financial year from 2017-18 onward. Covered invoices are reported to the Invoice Registration Portal for an IRN and signed QR code.
A one-off invoice works for a simple job when you already know the buyer details, GST treatment, line items, and payment term. It is enough for a single project milestone, a consulting fee, or a short service engagement where you can confirm whether the invoice needs GST e-invoicing before sending it. For micro or small enterprise suppliers covered by the MSMED Act, the agreed payment date cannot exceed 45 days from acceptance or deemed acceptance.
A managed workflow becomes necessary when billable time, expenses, non-billable work, rates, and invoice status need to stay connected. Everhour Billing & Invoicing converts tracked billable time and expenses into invoices, calculates invoice amounts from rates while excluding non-billable tasks, and supports client settings such as contacts, taxes, discounts, and payment terms. It can also export invoices to QuickBooks Online, Xero, or FreshBooks with status sync back to Everhour.

India invoice software should capture supplier GSTIN, recipient GSTIN or UIN when registered, invoice number, issue date, HSN or SAC, description, taxable value, GST rate, GST amount by tax type, and reverse-charge status where relevant. For inter-state supplies, it should also capture place of supply with the state name.
The supply type decides the GST split. CGST plus SGST or UTGST generally applies to intra-state supplies, while IGST applies to inter-state supplies. The invoice should not merge these into one generic tax line because the buyer needs the tax type for GST accounting and reconciliation.
A GST invoice serial number must be consecutive and unique for the financial year. It may contain letters, numbers, hyphen, dash, or slash, and it must stay within a limit of up to 16 characters. A long internal project code can break the format if it exceeds that limit.
GST e-invoicing applies to notified B2B taxpayers whose aggregate turnover exceeded more than Rs. 5 crore in any financial year from 2017-18 onward. Covered invoices must be reported to the Invoice Registration Portal for an IRN and signed QR code before they are treated as valid e-invoices.
For a micro or small enterprise supplier covered by the MSMED Act, the agreed payment date cannot exceed 45 days from acceptance or deemed acceptance. A longer commercial payment term creates delayed-payment exposure, including interest consequences, even if the buyer's standard procurement cycle is longer.
