Buying in bulk: How to optimize procurement at scale

In procurement, efficiency and cost control are everything. Buying in bulk is one strategy that delivers both. Bulk buying is the practice of purchasing large quantities of goods or services to reduce price per unit, streamline operations, and secure supply chain consistency.

Buying in bulk can help businesses of all sizes—from startups to enterprise-level operations—enhance inventory control, reduce lead times, and ultimately improve their bottom line. When implemented thoughtfully, it creates a competitive advantage in pricing, forecasting, and customer service.

Whether you’re looking to optimize cleaning supply orders for your office or cut costs on raw materials in manufacturing, it’s important to understand the benefits of bulk shopping, how to save money buying in bulk, and whether bulk purchasing makes sense for your organization.

What is bulk purchasing?

Bulk purchasing is the process of acquiring large quantities of goods or services in a single order, often to secure discounts and minimize reorder frequency. It can also help organizations reduce procurement cycles and meet long-term operational needs.

Unlike consumer bulk buying (e.g., at club stores), business bulk buying often involves larger quantities, specialized invoicing, and logistical considerations like pallet delivery or distributed shipments.

Common examples include:

• Products: Purchasing 1,000 printer cartridges for a corporate office network
• Services: Buying 12 months of janitorial service for multiple warehouse facilities
• Supplies: Ordering for multiple office locations by buying 300 rolls of toilet paper and paper towels, or buying in bulk for events, including 500 name badges or 100 branded bags

While buying in bulk offers many advantages, it also requires consideration of its constraints. For example, to make the strategy work, your organization needs:

• A flexible budget
• A supplier with a sufficient delivery capacity
• The ability to meet minimum procurement volumes, if applicable

Buying in bulk vs. wholesale

The terms “bulk buying” and “wholesale” are sometimes used interchangeably, but they serve different purposes and buyer types in the business world. 

Bulk buying refers to purchasing bulk products at a lower price per unit for the purpose of stocking up, while buying wholesale involves purchasing goods directly from manufacturers or distributors, typically at lower prices, with the intent to resell them. 

While both consist of buying in large quantities, wholesale is geared toward retailers and resellers, while bulk buying is ideal for organizations looking to save money on regular-use items.

For example:

• With bulk buying, a construction firm can buy a large quantity of safety helmets to equip job sites across multiple states.
• With wholesale purchasing, a hardware store can purchase helmets from a manufacturer at wholesale prices to sell to customers, such as a construction firm.
   

Knowing how bulk buying differs from wholesale can help you select the right suppliers and pricing models based on your business objectives.

Benefits of buying in bulk for businesses

When implemented strategically, bulk buying can drive measurable value across your procurement process. While the most obvious advantage is saving money, the benefits go far beyond cost.

Streamlined ordering and automated reordering

Placing fewer, larger orders through bulk buying reduces time spent on procurement tasks. Smart buying solutions like Amazon Business offer automated reordering tools that help you consistently replenish bulk supplies without manual effort.

You can also earn extra savings by setting up recurring deliveries with Subscribe & Save for frequently purchased products, which lets you save up to 15% per order.

Example: A school district can automate quarterly bulk orders of classroom supplies across multiple campuses using recurring orders.

Efficient inventory management

Buying in bulk enables proactive inventory control and minimizes stockouts. When combined with demand forecasting, businesses can optimize storage and reduce reactive purchasing. This works best with non-perishable goods.

Example: A tax preparation company can bulk buy printer ink and use data to distribute stock across locations based on seasonal demand.

Reduced procurement cycles

Frequent small purchases may seem manageable, but over time, they create a heavy burden for procurement teams. Rather than issuing purchase orders every couple of weeks, bulk buying lets you consolidate procurement into fewer cycles. This reduces administrative costs, supplier back-and-forth, and shipping fees.

Example: Instead of buying conditioner, body wash, and toothbrushes weekly from a grocery store, a small hotel can shift to quarterly bulk orders through an e-commerce platform. 

Cost savings

The most talked-about advantage of bulk buying is saving money, but this benefit comes with a few caveats. Bulk purchases typically offer a lower price per unit, especially when compared to purchases at large retailers like Costco or Walmart. 

Amazon Business offers several ways to maximize cost savings when buying in bulk:

• Quantity discounts may start from as few as two units.
• High-volume orders (e.g., 999+ units or $10,000+) can unlock custom pricing via the Request for Quote tool.
• You don’t need a Business Prime subscription to access these discounts, but Business Prime can help visualize your bulk spend and uncover more savings through advanced analytics.

Buying in bulk also lessens shipping, packaging, and handling costs, especially when using features like consolidated shipping or reduced packaging options.

However, the actual buying in bulk pros and cons you’ll experience depend on your situation. To truly save money, you need to have adequate storage space, understand product shelf life, and forecast your needs accurately. Overstocking can lead to waste, while underestimating can mean missed savings opportunities.

It's still a good practice to look for coupons, promotions, and wholesale prices when making large purchases.

How to evaluate if bulk buying makes sense for your organization

Before adopting a bulk buying strategy, assess whether it aligns with your operational and financial realities. It may be a good fit if your organization:

• Has predictable demand for products or services
• Has sufficient storage or distributed delivery capabilities
• Wants to optimize costs over time rather than just per transaction
• Can track and forecast usage effectively

Buying in bulk may not be ideal if:

• Your inventory has a short shelf life
• You face tight cash flow or limited credit
• You lack adequate storage or distribution infrastructure
• Your usage varies widely by season or customer demand

Amazon Business makes this evaluation easier with tools like Spend Visibility dashboards (a Business Prime feature), product analytics reports, and palletized delivery and shipment to multiple business locations.

Storage and space requirements for buying in bulk

Before placing a bulk order, calculate your total volume needs based on product size and quantity using the following steps:

1. Measure product dimensions and multiply by quantity.
2. Convert to cubic feet or meters.
3. Assess available storage in your facilities (shelves, racks, pallets).
4. Account for climate control needs if applicable.
5. Review product shelf life and rotation rates to avoid waste.

These steps help ensure you have sufficient space for bulk inventory, including any products that require climate control. 

Cash flow and payment terms

Bulk purchases often require significant upfront capital. Ensure your cash flow can support these investments without disrupting operations by considering:

• Working capital availability
• Supplier payment terms
• Eligibility for net terms through Pay by Invoice (subject to approval)
• Impact on liquidity and credit lines

You can also evaluate ROI using a formula like the following:

Bulk Buying ROI = (Savings per Unit × Quantity Purchased) – (Holding Cost + Storage Cost + Capital Cost)

If the result is positive and recurring, bulk buying may make financial sense.

Sustainability and environmental impacts

Buying in bulk can have an environmental impact by reducing packaging waste, emissions from multiple deliveries, and supplier redundancies. But it only benefits the environment if products are used efficiently and stored properly.

Our smart buying solution supports responsible purchasing with:

• Sustainability filters (e.g., ENERGY STAR®, FSC Certified)
• Tools to track spend on certified sustainable products
• Sustainable purchasing reports for eligible accounts

Note: While these features aid in goal setting, using Amazon Business does not guarantee your business will meet sustainability, environmental, or social standards.

How can I place a bulk order on Amazon Business?

Whether you're stocking up on office furniture, PPE, or tech accessories, Amazon Business offers two flexible methods for placing bulk orders.

1. Bulk ordering from your account menu

This ordering method is ideal for recurring or pre-identified products.

2. Navigate to “Buy in Bulk” from the account menu.
3. Use search filters to find bulk-eligible products.
4. Adjust quantity and view quantity discounts.
5. Add to cart and proceed with standard checkout.
6. Choose delivery preferences (e.g., pallet, consolidated delivery).

2. Using the Request for Quote (RFQ) tool

This method is best for large or one-time high-volume purchases.

Steps:

1. Go to your Amazon Business dashboard.
2. Select “Request for Quote.”
3. Enter the product name, quantity, and optional delivery instructions.
