For any business involved in selling products, whether as a retailer, wholesaler, or manufacturer, the costs associated with "buying inventory" are a significant component of operations. For accountants and Small to Medium-sized Business (SMB) owners, understanding how to account for these costs properly is fundamental. Unlike typical operating expenses like rent or utilities, the cost of buying inventory isn't immediately deducted in full. Instead, it's generally recovered through the "Cost of Goods Sold" (COGS) when the inventory is actually sold.

This guide will explain how inventory purchases are categorized, the crucial considerations in accounting for them, examples of costs involved, the tax implications surrounding COGS, and how Fyle can help track and manage these essential purchase transactions.

Buying Inventory Expenses Category: Understanding Cost of Goods Sold

When a business buys inventory, be it finished goods for resale or raw materials for manufacturing, these costs are not immediately treated as an expense on the income statement. Instead, they are recorded as an asset called "Inventory" on the balance sheet. The expense recognition occurs when the inventory is sold. At that point, the cost of the sold inventory is transferred from the Inventory asset account to an expense account called Cost of Goods Sold (COGS).

COGS is a direct cost associated with the revenue generated from selling products. It's a critical calculation for determining a business's gross profit.

Some Important Considerations When Accounting for Inventory Purchases

What to Include in the Cost of Inventory

The cost of purchased inventory includes the invoice price less any trade discounts. Additionally, other costs necessary to acquire the inventory should be included, such as:

  • Freight-in: Transportation charges to get the inventory to your business location are part of the inventory cost.
  • Cash discounts taken on purchases can either be credited to a separate discount income account or deducted from the total purchases for the year; consistency in method is key.

Uniform Capitalization Rules (UCR / Section 263A)

For some businesses, particularly manufacturers and larger resellers, the UCR requires capitalizing additional direct and indirect costs into the inventory value. These can include costs related to purchasing, storage, handling, and some administrative overhead.

Small Business Taxpayer Exception: Importantly, small business taxpayers (generally those with average annual gross receipts of $30 million or less for the 3 prior tax years, for 2024) who acquire property for resale are generally exempt from applying UCR to that resale inventory.

Inventory Valuation Methods 

Businesses must use a consistent method to value their inventory, such as:

  • First-In, First-Out (FIFO)
  • Last-In, First-Out (LIFO) – subject to specific IRS rules and requires use in financial statements.
  • Specific Identification The chosen method affects the calculation of COGS and ending inventory value.

Recordkeeping for Purchases

The IRS requires detailed records for all inventory purchases. Supporting documents include:

  • Canceled checks or other proof of payment/electronic funds transferred.
  • Cash register tape receipts.
  • Credit card receipts and statements.
  • Supplier invoices (detailing items, quantities, and prices).

Exception for Small Business Taxpayers Regarding Inventory Tracking

Qualifying small businesses (as defined above) may choose not to keep an inventory in the traditional sense for tax purposes. They can opt for a method that treats inventory as non-incidental materials and supplies, deducting the cost of these items in the year they are first used or consumed (i.e., sold). Alternatively, they can use a method that conforms to their financial accounting treatment of inventories. This can significantly simplify bookkeeping.

Examples of Costs Included in Buying Inventory

The costs capitalized into inventory generally include:

  • The invoice price of merchandise bought for resale (less trade discounts).
  • The cost of raw materials and parts purchased for manufacturing into finished products.
  • Freight-in or transportation costs to bring the inventory to your business.
  • Import duties, if applicable.
  • For manufacturers (or resellers subject to UCR), applicable direct labor and allocable indirect costs such as purchasing-related costs, off-site storage, and handling.

Tax Implications of Buying Inventory Expenses

The primary way the cost of buying inventory impacts your taxes is through the Cost of Goods Sold (COGS) calculation:

Cost of Goods Sold (COGS)

This is the most significant tax implication. COGS is deducted from your gross receipts to determine your gross profit. 

The basic formula is: 

COGS = Beginning Inventory + Net Purchases (and other capitalized costs) - Ending Inventory

(Net Purchases include costs like freight-in and are reduced by items withdrawn for personal use)

Timing of Deduction

Inventory costs are effectively deducted in the tax year the inventory is sold, not when purchased (unless using the specific small business taxpayer methods described earlier).

Accounting Method for Purchases and Sales

If inventory is an income-producing factor, you must generally use an accrual method of accounting for purchases and sales, unless you qualify for the small business taxpayer exception.

Uniform Capitalization Rules (UCR)

If your business is subject to UCR (e.g., you are a manufacturer or a reseller not meeting the small business exception), you must include certain direct and indirect costs in your inventory value. This can delay the deduction of these costs until the inventory is sold.

Items Withdrawn for Personal Use

If you withdraw merchandise for personal or family use, its cost must be excluded from COGS (usually by reducing purchases).

Donated Inventory

Special rules apply if you donate inventory. Generally, the cost of the donated inventory must be removed from your opening inventory or purchases and is not part of COGS. The amount of the charitable contribution deduction may also be limited.

How Fyle Can Automate Expense Tracking for Inventory Purchases

While Fyle isn't an inventory management system itself, it plays a vital role in capturing and organizing the initial purchase transactions and related documentation, which are crucial for accurate inventory accounting and COGS calculation:

Capturing Purchase Invoices and Receipts

  • Email Forwarding & OCR: Supplier invoices for inventory received via email (e.g., from Gmail or Outlook) can be forwarded directly to Fyle. Fyle's OCR technology can extract key data, minimizing manual entry.
  • Mobile App: Receipts for smaller inventory purchases or related costs (like freight paid on delivery) can be snapped and uploaded via the Fyle mobile app.

Real-Time Credit Card Transaction Feeds 

If inventory purchases are made using a corporate credit card, Fyle captures these transactions in real-time, providing immediate visibility into these outflows.

Matching and Reconciliation

Fyle can automatically match uploaded invoices or receipts with the corresponding credit card transactions, streamlining the reconciliation process for inventory purchases.

Categorization for Accounting Handoff

Payments for inventory can be categorized within Fyle (e.g., "Inventory Purchases," or by supplier name). This organized data, along with attached documentation, can then be easily exported to your main accounting system.

Approval Workflows for Purchase

If inventory purchases require internal approval before payment, Fyle’s customizable approval workflows can manage this process efficiently.

Integration with Accounting System

Fyle seamlessly integrates with accounting software like QuickBooks (Online & Desktop), Xero, NetSuite, and Sage Intacct. This ensures that data on inventory purchase transactions is accurately transferred, allowing accountants to update the inventory asset account and subsequently calculate COGS correctly within the accounting system.

Spend Visibility

Fyle provides dashboards and reports that can help businesses track spending on inventory purchases by supplier or over time, aiding in cash flow management and identifying purchasing trends.

By using Fyle to meticulously capture and document all transactions related to buying inventory, businesses provide their accountants with the accurate source data needed for proper inventory valuation, COGS calculation, and tax reporting.
