Effective Material Control: Objectives and Advantages

Walk into any manufacturing unit and you will notice something simple but expensive going wrong all the time: godowns stuffed with raw material that no one is using, or production lines standing idle because a single component ran out. Both situations drain money. Material control is the cost accounting function that exists to prevent exactly this – regulating how materials are bought, stored, and used so that production never stalls and capital never sits idle in a warehouse.

What is material control? 🔗

Material control refers to the systematic regulation of procurement, storage, and issue of materials so that production flows smoothly without tying up excessive capital in stock. It covers everything from raising a purchase requisition to issuing materials to the shop floor, and it touches purchasing, receiving, inspection, storage, and record-keeping along the way, as outlined in the ICAI’s study material on material cost.

It is worth separating this from “materials management,” which is the broader function of planning and coordinating material flow across a business. Material control is narrower – it is specifically about keeping quantity, quality, and cost of materials within planned limits at every stage.

Why material control matters in cost accounting 🔗

Materials are usually the single largest element of cost in a manufacturing business, often accounting for more than half of the total cost of production, according to Accounting Notes’ analysis of manufacturing cost structures. When one input dominates the cost sheet this heavily, even small inefficiencies in how it is bought or stored translate into a large hit on profitability. This is why cost accountants treat material control as a core control point, not an operational afterthought.

Objectives of material control 🔗

A material control system is built around a handful of clear goals. Every technique used later – stock levels, EOQ, ABC analysis – exists to serve one of these objectives.

Ensuring an uninterrupted supply 🔗

The first job of material control is to make sure production never stops for want of materials. A single missing component can halt an entire assembly line, and the cost of idle labour and machinery during a stoppage is often far higher than the cost of the material itself. Material control systems build in buffer stock and reorder triggers precisely to avoid this, as noted in Management Note’s overview of material control objectives.

Avoiding overstocking and understocking 🔗

Overstocking locks up working capital that could otherwise fund operations or expansion, and it raises storage, insurance, and obsolescence costs. Understocking, on the other hand, risks production stoppages. Material control aims to strike a balance – enough stock to keep operations running, but not so much that capital is idle.

Purchasing on favourable terms 🔗

Material control also involves buying the right quality at the right price. This means negotiating bulk discounts, favourable credit terms, and reliable delivery schedules with suppliers, while still meeting the quality standards fixed for the finished product. Purchasing decisions here directly affect the cost sheet, so they fall squarely within the scope of cost accounting.

Proper storage and handling 🔗

Materials sitting in a store are vulnerable to theft, spoilage, obsolescence, and simple mishandling. A good storage system – proper bins, climate control where needed, and restricted access – protects the value of the stock between the time it is purchased and the time it is issued to production.

Minimising wastage and maintaining accurate records 🔗

Finally, material control aims to reduce wastage during handling and consumption, and to maintain accurate, up-to-date records of what has been received, issued, and remains in stock. This record accuracy feeds directly into costing and financial reporting.

Advantages of an effective material control system 🔗

When these objectives are met consistently, the benefits show up across the business – not just in the stores department but in the final cost sheet and the balance sheet.

An efficient material control system also strengthens internal control more broadly – it fixes responsibility on the staff handling materials at each stage and makes it easier to prepare periodic financial statements, since stock figures are always current rather than reconstructed at year-end, a point highlighted by Taxmann’s explainer on material control systems for CA students.

Techniques used to achieve material control 🔗

Objectives and advantages are the “why” of material control. The “how” comes down to a set of established techniques that cost accountants use to keep stock at the right level.

Setting stock levels 🔗

Businesses typically fix a minimum level, maximum level, reorder level, and danger level for each material. These act as trigger points – for instance, stock touching the reorder level automatically signals that a fresh purchase order should be placed, well before the material actually runs out.

Economic order quantity (EOQ) 🔗

Every purchase involves two competing costs: the cost of placing an order and the cost of carrying (storing) the stock once it arrives. Order too often and ordering costs pile up; order too much at once and carrying costs pile up instead. Economic order quantity is the order size that minimises the combined total of these two costs, as explained by the Corporate Finance Institute’s guide to EOQ. It is one of the most widely used tools in a material control system precisely because it turns a judgement call into a calculable number.

ABC analysis 🔗

Not every item in a store deserves the same level of attention. ABC analysis – sometimes read as “Always Better Control” – groups materials into three categories based on their value and consumption: a small number of high-value “A” items that need close monitoring, a moderate “B” category, and a large number of low-value “C” items that can be controlled with simpler, less time-consuming procedures. This selective approach concentrates management effort where it matters most.

Perpetual inventory system 🔗

Rather than waiting for periodic physical stock-taking, a perpetual inventory system updates stock records – through bin cards and stores ledgers – after every single receipt and issue transaction. This gives an accurate, real-time picture of stock at any point, supports faster preparation of interim accounts, and reduces the disruption that comes from shutting down operations for a full physical count.

Bringing it together 🔗

Material control is not a single technique but a coordinated system spanning purchase, storage, and issue. Its objectives – continuous supply, balanced stock levels, favourable purchasing, safe storage, and minimal wastage – feed directly into its advantages: lower capital tied up, reduced costs, accurate valuation, and uninterrupted production. For anyone studying cost accounting, this topic is a good reminder that cost control rarely comes from cutting corners; it comes from disciplined, well-recorded processes applied consistently.

What do you think? If a business held zero safety stock to minimise carrying costs, what risks would it be taking on in exchange? And between EOQ and ABC analysis, which technique do you think would matter more for a business where a handful of raw materials make up most of the purchase value?
