Supplier invoices are documents from suppliers to their buyers that contain requests for payments for the supplies made. The document contains information regarding the supplies, the quantity or scope of supplies, taxes, amounts payable, and payment terms.
For businesses, invoices are more than just requests for payment. Invoices can be used for bookkeeping purposes and, when required, GST documentation purposes, recording expenses, reconciliation, and input tax credits.
What Is a Supplier Invoice?
Supplier invoices are documents sent by a supplier to a business following the supply of goods or services. Supplier invoices inform the business of the amount to pay and supply information.
A standard invoice includes the following details:
- Supplier
- Buyer
- Supplied products/services
- Quantity
- Rate
- Value that is taxable
- The tax levied on it
- The total amount
- Terms of payment
- The due date of the payment
- Invoice number
- The date of invoice
In case the manufacture provides the raw material worth ₹2 lakh to the company, the manufacture will make an invoice reflecting the products supplied along with GST and the invoice amount.
Importance of Supplier Invoice:
The invoice of suppliers is the document that makes the formal entry of the purchases made by the business.
Some of the uses of the supplier invoice are:
- Recoding the expenses of the business
- Keeping track of the accounts payable
- Confirming the purchases made
- The calculation of GST liability
- Eligibility of the input tax credit
- Supplier reconciliations
The proper maintenance of the invoice also makes it easy to detect the outstanding invoices and resolve disputes related to quantity, rate, or taxation.
What Information Does a Supplier Invoice Contain?
The exact format can vary, but a business invoice generally contains important transaction and tax information.
These facts must be confirmed before a company processes the invoice for payment.
Supplier Invoice versus Purchase Invoice
The phrases supplier invoice and purchase invoice are sometimes interchangeably used to refer to the same process viewed from two different angles.
A supplier raises an invoice against a buyer, who views the invoice as a purchase invoice. But from the supplier’s point of view, it is a sales invoice.
Thus, a single document can serve both as a supplier invoice and purchase invoice, depending on who issues it.
Types of invoices businesses need to know
Depending on the type of business transaction, there will be different types of invoices.
Tax Invoice
This is the type of invoice that applies to all taxable transactions requiring GST invoices.
It usually includes pertinent tax information such as GSTIN, taxable value, GST rate, and tax components.
Commercial Invoice
A commercial invoice is normally used in international business transactions in order to detail the sale of goods and necessary information for both customs and commercial purposes.
The following information can be included:
- Exporter
- Importer
- Product description
- Quantity
- Unit price
- Total value
- Currency
- Country of Origin
- Shipping information
However, a commercial invoice is not necessarily a GST tax invoice.
Proforma Invoice
Proforma invoice is generally a pre-sale document that details an anticipated transaction.
It can be used to outline the following:
- Expected price
- Product details
- Quantity
- Payment terms
- Estimated transaction value
It should not be confused with tax invoices.
GST Invoice Requirements in India
In case a business is registered under GST, then the invoices must conform to the GST invoice rules.
There could be some of the following items included in a GST invoice:
- Name of the supplier
- Address
- GSTIN
- Invoice number
- Date
- Buyer’s details
- Buyer GSTIN
- HSN/SAC
- Description
- Quantity
- Value
- Taxable value
- GST rate
- CGST
- SGST/UTGST
- IGST
- Total value of the invoice
The taxes applicable would depend on the type and location of supply.
The businesses should make sure that their invoicing system conforms to the applicable GST rules.
GSTIN and GST Registration
A business registered under GST gets a GSTIN (Goods and Services Tax Identification Number).
The GSTIN helps identify the business under GST regulations.
Prior to the recording of an invoice, the buyer needs to verify certain details about the supplier, especially if he is eligible for input tax credit.
General:
- CGST stands for Central Goods and Services Tax.
- SGST stands for State Goods and Services Tax.
- IGST stands for Integrated Goods and Services Tax.
For a relevant intra-state supply, CGST along with SGST/UTGST may apply.
For a relevant inter-state supply, IGST may apply.
It should be noted that enterprises need to consider applicable GST regulations, not just the form of invoices provided by the supplier.
HSN and SAC Codes in Invoices
The HSN code is used to classify goods, whereas the SAC code is used to classify services.
These codes make it possible to understand what kind of supply we are dealing with.
For instance:
- Goods → HSN
- Services → SAC
The relevant requirements regarding HSN/SAC coding may vary depending on the taxpayer and the relevant transaction.
Wrong classification may lead to numerous issues connected to proper tax reporting, invoice filling and reconciliation.
Differences Between Taxable Value and Invoice Total
The taxable value is the value on which GST is calculated in accordance with the relevant requirements.
The invoice total is the total value payable after applying relevant taxes.
For example:
Organizations need to be clear about the distinction between taxable amount and final invoice value.
Payment Terms and Payment Due Date
Payment terms indicate how and when payment is expected from the buyer.
Some examples include:
- Payment on delivery
- Advance payment
- Net 15 days
- Net 30 days
- Net 60 days
- Partial payment
- Milestone payment
The payment due date indicates when the payment is expected according to the payment terms set.
Organizations need to record due dates appropriately as late supplier invoices have an impact on business relationship, cash flow and credit arrangement.

Input Tax Credit and Supplier Invoices

It needs to comply with the relevant statutory conditions and documentation requirements.
Organizations should check the following information:
- Supplier Name
- GSTIN
- Invoice Number
- Invoice Date
- Tax Amount

- Receipt of Goods or Services

What Is an E-Invoice?
An e-invoice is an electronically authorized GST invoice issued using the prescribed e-invoicing system for those taxpayers and transactions that are eligible according to the relevant rules.
In the context of India’s GST regime, the applicability of e-invoices depends on criteria notified, such as turnover and type of transaction.
Where the applicability of e-invoicing exists, it becomes necessary to adhere to the prescribed process and not consider a generic PDF invoice sufficient.
It is advised to review the relevant threshold and rules, as the GST requirements change from time to time.
E-Invoice vs Supplier Invoice
The e-invoice is not a totally separate commercial transaction. It is a prescribed system of electronic invoicing.
Organizations that fall under e-invoicing must ensure that their invoice generation system is correctly set up.
Supplier Invoice and E-Way Bill
The e-way bill refers to the movement of goods, and is different from the actual invoice.
As applicable, organizations may require:
- Invoice
- E-way bill
While the invoice determines the information regarding the supply and taxation process, the e-way bill enables compliance regarding the movement of goods according to GST laws.

-
Incorrect GSTIN
An incorrect GSTIN may cause reconciliation and input tax credit issues for the buyer.
