What is the difference between a purchase order and an invoice?

A purchase order (PO) is issued by the buyer before the purchase — it is a commitment to buy specific goods at an agreed price. An invoice is issued by the vendor after delivery — it is a request for payment. In a well-controlled procurement process, every vendor invoice should reference a matching PO number. The PO number on both documents enables 3-way matching: PO → Goods Receipt Note (GRN) → Invoice, which prevents unauthorised purchases, overpayments, and fraud.

Is a purchase order legally binding in India?

Yes. Under the Indian Contract Act, 1872, a purchase order becomes a legally binding contract once the vendor accepts it — either explicitly (by signing/acknowledging) or implicitly (by fulfilling the order). Both parties then have enforceable obligations: the vendor must deliver as specified, and the buyer must pay as agreed. This is why accurate PO terms are critical: they define the legal commitments of both parties.

Is GST applicable on purchase orders in India?

A purchase order itself does not trigger GST — GST is levied when the vendor raises a tax invoice against the PO. However, a GST-compliant PO format should include: buyer and vendor GSTINs, HSN/SAC codes for each item, applicable tax rates (CGST + SGST for intra-state, IGST for inter-state), and taxable values. Including GST estimates in the PO helps both parties budget accurately and ensures the final invoice matches the agreed terms.

What should a purchase order include?

A complete purchase order should include: unique PO number, issue date and expected delivery date, buyer's name, address, and GSTIN, vendor's name, address, and GSTIN, ship-to address (if different), itemised list of goods/services with HSN/SAC codes, quantities, units, and unit prices, applicable taxes (CGST/SGST/IGST/VAT), discount if any, total order value in the correct currency, payment terms, and any special terms and conditions.

What are the 4 types of purchase orders?

The four main types of purchase orders are: (1) Standard PO — a one-time order for specific items at a defined price and delivery date; (2) Blanket PO — a long-term agreement with a vendor for repeated purchases over a period (typically 12 months) without fixed delivery dates; (3) Contract PO — establishes agreed terms without specifying quantities, which are confirmed in separate release orders; (4) Planned PO — created in advance for future purchases based on procurement planning, with tentative delivery schedules.

What currencies does the PO generator support?

The ThinkForU PO Generator supports 13 currencies: INR (Indian Rupee), USD (US Dollar), EUR (Euro), GBP (British Pound), AED (UAE Dirham), SAR (Saudi Riyal), SGD (Singapore Dollar), AUD (Australian Dollar), CAD (Canadian Dollar), JPY (Japanese Yen), CNY (Chinese Yuan), MYR (Malaysian Ringgit), and any custom currency with your own symbol and code.

What is the difference between a purchase order and a quotation?

A quotation is sent by the vendor to the buyer — it is the vendor's offer of price for specified goods/services. A purchase order is sent by the buyer to the vendor — it is the buyer's formal acceptance of (usually) the quoted terms. The typical procurement flow is: Buyer issues RFQ (Request for Quotation) → Vendor sends Quotation → Buyer sends Purchase Order → Vendor delivers goods → Vendor sends Invoice → Buyer pays.

Does the purchase order generator work on mobile?

Yes. The ThinkForU Purchase Order Generator is fully responsive and works on all devices including Android smartphones, iPhones, tablets, and desktop computers.

What is a Purchase Order (PO)?

● Definition

A purchase order (PO) is a legally binding commercial document issued by a buyer to a vendor that formally authorises a purchase transaction. It specifies the goods or services to be purchased, quantities, agreed unit prices, delivery date, payment terms, and shipping details. Once the vendor accepts the PO — explicitly or by fulfilling it — it becomes an enforceable contract under the Indian Contract Act, 1872. In accounts payable, POs are the foundation of 3-way matching: PO → Goods Receipt Note (GRN) → Vendor Invoice, which prevents unauthorised purchases, overpayments, and fraud.

4 Types of Purchase Orders You Should Know

Standard PO — The most common type. A one-time order for specific items at a fixed price and delivery date. Used when you know exactly what you need.
Blanket PO — A long-term agreement with a vendor for repeated purchases over a period (typically 12 months) without fixed delivery dates or quantities upfront. Good for regular suppliers.
Contract PO — Establishes agreed pricing, terms, and conditions without specifying quantities. Specific quantities are confirmed through separate release orders against the contract.
Planned PO — Created in advance based on procurement planning with tentative delivery schedules. Quantities and dates are confirmed as the need arises.

GST Compliance in Purchase Orders

While a purchase order itself does not trigger GST (GST is levied when the vendor issues a tax invoice), a GST-compliant PO format should always include both buyer and vendor GSTINs, HSN/SAC codes for each line item, applicable tax rates (CGST + SGST for intra-state, IGST for inter-state), and the estimated taxable values. This ensures the final invoice from the vendor matches the PO exactly and supports seamless ITC (Input Tax Credit) claims.

Under the Indian Contract Act, 1872, once a vendor accepts a PO, both parties are legally bound. The vendor must deliver as specified and the buyer must pay as agreed. Any deviation — change in quantity, price, or delivery date — should be issued as a PO amendment, not a verbal agreement.

Frequently Asked Questions About Purchase Orders

A purchase order is a legally binding commercial document issued by a buyer to a vendor, formally authorising the purchase of specific goods or services at agreed prices. It specifies items, quantities, unit prices, delivery date, payment terms, and shipping details. Once the vendor accepts the PO, it becomes an enforceable contract under the Indian Contract Act, 1872.

A purchase order is issued by the buyer before the purchase — it's a commitment to buy. An invoice is issued by the vendor after delivery — it's a request for payment. Every vendor invoice should reference the original PO number. In a controlled procurement process, invoices are matched against the PO and Goods Receipt Note (GRN) in a 3-way match before payment is approved.

Yes. Under the Indian Contract Act, 1872, a purchase order becomes legally binding once the vendor accepts it — either explicitly (by acknowledging in writing) or implicitly (by beginning to fulfil the order). Both parties then have enforceable obligations: the vendor to deliver as specified, and the buyer to pay as agreed. This is why PO terms must be precise and accurate.

A PO itself doesn't trigger GST — GST is levied when the vendor raises a tax invoice. However, a GST-compliant PO should include both GSTINs, HSN/SAC codes, tax rates (CGST+SGST for intra-state, IGST for inter-state), and estimated tax values. This ensures the vendor's final invoice matches the PO and allows seamless Input Tax Credit (ITC) claims.

The four types are: (1) Standard PO — a one-time order for specific items at fixed prices; (2) Blanket PO — a long-term vendor agreement for recurring purchases without fixed quantities; (3) Contract PO — sets terms and pricing without specific quantities, which are released separately; (4) Planned PO — created in advance based on procurement forecasts with tentative dates confirmed later.

A complete PO should include: unique PO number, date, expected delivery date, buyer's name/address/GSTIN, vendor's name/address/GSTIN, ship-to address (if different), itemised list with descriptions/HSN codes/quantities/units/prices, applicable taxes (CGST/SGST/IGST/VAT), discount if any, total order value, payment terms, shipping mode, and any special instructions or terms.

3-way matching is a standard accounts payable control that verifies three documents before approving vendor payment: (1) the Purchase Order, (2) the Goods Receipt Note (GRN) confirming delivery, and (3) the vendor's Invoice. All three must match in item, quantity, and price. This prevents unauthorised purchases, duplicate payments, and procurement fraud. The PO number on all three documents enables this match.
