What the purchase department does
The cycle starts with a purchase requisition from a user department or from the material plan. The buyer checks specifications, invites quotations from approved vendors, prepares a comparative statement, negotiates and raises the purchase order once it is approved. After that the buyer follows up delivery, resolves quality rejections with the vendor, and makes sure the bill matches the PO and goods receipt so finance can pay. Strategic sourcing looks further ahead: rate contracts for the year, alternate vendors for critical items, import sourcing and cost reduction. Vendor development teams visit and audit new suppliers before they are approved.
- Direct procurement: raw material, packing material and components for production
- Indirect procurement: services, capital equipment, IT, stationery and facilities
- Vendor development: supplier search, audits, approval and rating
- Contracts: annual rate contracts, service agreements and price revisions
Purchase team size at 50, 500 and 5,000 employees
In a company of 50, buying is usually done by the owner or by a purchase executive who also keeps the stores register, and large orders need the owner's signature. At about 500 employees, a purchase manager leads buyers split by category, such as steel and castings, packing material, electricals and general items, along with a purchase assistant for PO entry and follow-up. Capital purchases like machines still go to a director.
In a company of 5,000, a chief procurement officer or head of procurement runs category managers for major spend areas, a strategic sourcing team, a vendor development and supplier quality team, an import and customs cell, and plant purchase teams that buy locally within limits. A procurement excellence team tracks savings, PO cycle time and vendor performance, and indirect spend may be handled from one central office in a city like Pune or Chennai.
How purchase works with stores, quality and finance
User departments raise requisitions and approve the technical specification; purchase owns the commercial side. Stores receives material and records the goods receipt note, and quality inspects it before acceptance, so a rejected lot comes back to purchase for replacement or a debit note. Finance pays vendors against the three-way match of PO, goods receipt and invoice, and questions any bill without a PO. Planning or supply chain tells purchase what to buy and when. Legal reviews long-term contracts, and internal audit samples purchase files to check that quotations were taken and approvals followed.
Purchase order approval limits and reporting lines
Approval limits are written into a delegation of authority. An illustrative matrix: the purchase manager approves POs up to ₹2 lakh, the head of procurement up to ₹25 lakh, the CFO up to ₹1 crore, and the managing director above that, while single-vendor or emergency purchases need one level higher. Buyers report to category managers, who report to the head of procurement, who reports to the COO, CFO or supply chain head. Plant purchase officers usually take daily needs from the plant head and follow central procurement on rates, vendors and policy. Buyers should never approve their own vendor additions, which keeps the vendor master clean.

What is the difference between procurement and purchasing?
Purchasing is the transactional part: raising purchase orders, following up delivery and matching bills. Procurement is wider and includes deciding what to buy, finding and approving vendors, negotiating rate contracts, managing supplier risk and reducing total cost. Small companies use the words interchangeably, while large companies have procurement heads who own strategy and buyers who execute.
What is the hierarchy in a purchase department?
Purchase departments usually have five or six steps: purchase assistant, purchase executive or buyer, senior buyer, purchase or category manager, head of procurement and, in large companies, a chief procurement officer. Specialist roles such as vendor development engineer, import executive and sourcing analyst sit alongside the buying line and report to their own managers.
Who approves purchase orders in a company?
Purchase orders are approved according to a delegation of authority that sets rupee limits by level. For example, a purchase manager may approve small orders, the head of procurement medium ones, and the CFO or managing director large or capital orders. Emergency and single-vendor purchases usually need one level higher than normal.
Who does a purchase manager report to?
A purchase manager usually reports to the head of procurement or supply chain. In smaller companies the line goes to the plant head, the CFO or directly to the managing director. In multi-plant companies, plant purchase managers often work to the plant head for daily requirements and to central procurement for vendors and rates.
