A purchase order is a commercial source document that is issued by a business’ purchasing department when placing an order with its vendors or suppliers. The document indicates the items to be purchased, such as the types of goods, quantity, and price. In simple terms, it is the contract drafted by the buyer when purchasing goods from the seller. Tax-complaint purchase orders ensure a smooth flow of input tax and its credit that becomes a boon for the purchaser or buyer.

Maintaining Indian GST compliance PO involves considering purchase orders as a crucial component. Although they might appear as additional paperwork in accounting, understanding their timing and purpose extends significant business advantages.

Whether overseeing a small enterprise or managing procurement for a giant corporation, implementing an effective purchase order system can notably enhance the efficiency of your company’s purchasing procedures.

Importance of Properly Formatted GST Purchase Orders

  • Optimise Time Management

Investing a few additional minutes in creating purchase orders (POs) results in substantial time savings in the long term. Initially, an established PO system simplifies the ordering process through features like punch-out catalogues and item catalogues.

Once the system is in place, accessing approved products and placing orders becomes easy. Routine purchases trigger automatic PO generation, while for new orders, extensive automation streamlines both PO creation and order placement. Time is further saved upon order receipt as verification merely involves comparing the invoice against the purchase order to ensure accuracy. The system conveniently stores all necessary purchasing records, providing easy access.

  • Aid in Budget Management

In planning a sizable project, utilising purchase orders aids in budget management. To generate precise POs, calculating order quantities before project commencement offers a clearer understanding of the required budget allocation.

However, the utility of purchase orders extends beyond large projects. Even in managing day-to-day business purchases, the price and quantity details on POs offer insights into the company’s profitability by indicating sales requirements. Accessing past purchase records also supports effective budgeting by leveraging historical spending data to plan future budgets better.

  • Facilitate Strategic Planning

Meticulous purchasing records serve as a tool for future anticipation and planning. These records offer valuable insights into company performance, enabling analysis of product trends, market cycles, and expenditure patterns.

While most purchase order systems automatically generate this information, not all are proficient at providing easily accessible data. An adequate system should adeptly manage digital documents alongside generating comprehensive reporting for detailed data insights.

  • Manage Unexpected Expenditures

Employing purchase orders is an early alert system for unforeseen expenses. As most purchases require a submitted PO, any expense needs are documented as soon as they arise. A scenario where a department faces an unplanned expense illustrates this benefit. Upon placing the order, the accounts payable department becomes aware of it immediately rather than discovering it upon invoice receipt. This early awareness aids in smoother budgeting, planning, and inter-departmental communication.

  • Prevent Errors

Purchase orders are comprehensive documentation detailing ordered items and prices, effectively communicating purchase specifics. This documentation safeguards against errors during ordering, preventing misunderstandings that might occur during phone-based orders.

Referencing POs becomes crucial in disputes regarding ordered items, offering a tool to rectify internal mistakes or resolve issues between the organisation and its suppliers.

Components of a GST Purchase Order

GST PO format must encompass comprehensive details concerning the company making the purchase and the vendor. Specific fields, including quantity, price, description, taxes, and payment terms, must be accurately filled out to ensure mutual agreement between both parties. If any inconsistencies arise, referencing the purchase order can serve as a validation.

  • Contact Information

Complete contact details, such as both companies’ names, addresses, email addresses, and phone numbers, are essential. Given that the ordering business and the vendor will utilise the purchase order, comprehensive contact information is imperative for future correspondence and interactions.

  • PO Number

Assigning a distinct and clear purchase order number is vital for efficient tracking by the purchasing company and the external vendor, often within a centralised computer system. This facilitates quick and easy access to pertinent information for both parties.

  • PO Number – A unique number is used to track the order.
  • PO Date – The day the purchase order is issued
  • Customer Details include the buyer’s company name, registered address, and GST information.
  • Supplier ID – The buyer assigns a Unique Vendor ID to a specific vendor.
  • Item SKU

For orders involving raw materials or distinct items, individual SKU (Stock Keeping Unit) numbers should be included in the purchase order. This inclusion ensures accuracy in item selection, packaging, and invoicing while also serving as a cross-reference for received items.

  • Item Description

In the GST purchase order, it is imperative to offer a detailed description of items, including their names and identifying characteristics such as size, colour, or model number. This level of detail aids in easier identification than relying solely on alphanumeric numbers or barcodes.

  • Quantity

Precisely listing the number of each ordered item is crucial. Clear correspondence between quantities, item numbers, and descriptions is essential in cases where specific quantities are back-ordered or unavailable.

  • Price

Listing prices for each item alongside their respective quantities ensures transparency for both parties regarding the original charges. Any discounts or sale prices are typically itemised separately on the purchase order.

  • Subtotals, Taxes, and Totals

These figures, usually located at the bottom right of the purchase order, provide a comprehensive overview of the order. They detail taxes being charged and present the total, allowing both parties to understand the financial aspects of the transaction. Any applied discounts can also be factored into this section.

  • Payment Due Date

Including the agreed-upon payment terms and due date on the purchase order aligns the purchasing company and the vendor. It establishes clarity regarding billing and payment schedules, ensuring mutual understanding of when invoices are due for payment.

  • Information Regarding Delivery

A purchase order form should encompass particulars concerning order completion and delivery procedures. Essential details to incorporate are as follows:

  • The recipient’s address for delivery
  • The designated recipient’s name
  • The business conducting the transaction (which might differ from the delivery destination)
  • Charges associated with shipping and the chosen shipping approach
  • Additionally, billing particulars might be incorporated, encompassing the billing address (which could potentially differ from the shipping address) and the name of the entity responsible for payment.


Common Mistakes in GST Purchase Orders

GST is considered the most complex yet highly smooth functioning taxation system any nation has ever introduced. In its infant stages, there was lots of confusion amongst all the taxpayers, which gave rise to mistakes while formulating the PO or filling of GST. Given below are a few such mistakes commonly made by taxpayers and authorities, which should be read thoroughly:

  • Failure to Remit GST Under the Reverse Charge Mechanism (RCM)

The Reverse Charge Mechanism (RCM) alters the tax liability from the seller to the buyer, making the buyer responsible for paying taxes on goods and services purchased. Certain businesses fall under RCM for specific supplies according to GST regulations. Notably, providing services by goods transport agencies is a typical instance where the buyer assumes payment responsibility. Furthermore, the supplier is exempt from GST payment on such supplies to prevent dual taxation.

  • Omission of Exempted Turnover in GST Filings

Zero-rated supplies do not impact a taxpayer’s GST liability but should still be disclosed during GST return filing. All GST-registered businesses must report exempted or Nil-rated sales in GSTR 3B and GSTR 1. Under the Indian GST compliance, if a business fails to do so, it may be considered concealment of facts and could result in penalties.

  • Unauthorised Use of Composition Scheme Benefits

The Composition Scheme in GST aims to ease the tax compliance burden for small-scale taxpayers with turnovers below Rs. 1.5 Cr. Utilising these benefits without meeting the eligibility criteria might lead to unforeseen GST liabilities. Indian GST invoice requirements are very straightforward, if you are eligible, enjoy tax credits and rebates, and if not, then misleading might lead to serious consequences.

  • Misreporting Tax Under Incorrect GST Classification

The GST framework comprises various tax heads under which filings must be accurately reported. However, taxpayers often make errors by declaring GST liabilities or Input Tax Credits (ITC) under incorrect GST categories. Additionally, erroneous GST payments and interest filings under inappropriate heads can lead to cash flow issues and calculation discrepancies.

  • Failure to Reconcile GSTR-3B and GSTR-1

Regular monthly reconciliation between GSTR-3B and GSTR-1 ensures filing accuracy and avoids discrepancies. Discrepancies in these filings can result in revenue losses and may prompt inquiries or notices from tax authorities, demanding careful attention and assessment by taxpayers.

1. What is the definition of a purchase order?

A purchase order, often called a PO, is an official document a customer sends to a vendor to authorise a transaction. It contains vital purchase-related specifics such as the order date, total amount, pricing, payment terms, and delivery date.

2. How many categories of purchase orders exist?

There are five categories of purchase orders:

  • Standard Purchase Orders
  • Planned Purchase Orders 
  • Blanket Purchase Orders 
  • Contract Purchase Orders 
  • Digital Purchase Orders

3. What is the significance of a PO number?

A PO number is a unique identifier that tracks an order throughout its process.

4. Can an individual who has chosen the composition scheme for tax payment claim an Input Tax Credit on their inbound supplies?

No, it is not possible. A taxable individual who opts for tax payment under the composition scheme is excluded from the credit chain. They are unable to claim credit for their input supplies.

5. What distinguishes a purchase order from an invoice?

The primary distinction between a purchase order and an invoice lies in their purposes: a purchase order serves as a request for goods or services, while an invoice serves as a request for payment. Typically, the buyer issues a purchase order, whereas the seller issues an invoice.

6. How do purchase orders and invoices impact accounts payable?

A purchase order initiates the accounts payable procedure, while the invoice is the formal solicitation for payment, which the accounts payable department handles.

7. What is a digital form of purchase order?

Digital forms are a relatively new development. Businesses can use digital tools and document processing programs to make PO production and processing consistent across all their orders.

8. After receiving the PO, what does the seller do?

Buyers create purchase orders, while sellers draft invoices. When particular payment terms like “net 30,” “net 60,” or “FOB” are established, sellers issue an invoice to request payment. They might also send an invoice with a zero balance to confirm the receipt of payment for the order.

9. Mention one significant difference between purchase order and invoice.

Upon receiving the PO format, the seller assesses its details to ascertain if they can meet the requirements. A binding contract is formed once the seller approves the PO, rendering it enforceable. The seller must send the buyer back an authorised copy of the PO as part of this procedure.

10. What happens if a taxpayer forgets to mention GSTIN?

A GST tax invoice without GSTIN details is considered invalid. GST-registered businesses that issue a wrong invoice must face penalties and non-compliance charges. An automated billing solution like CaptainBiz will auto-populate the GST details so you will never miss including the mandatory information.
