Regular Audits and Cycle Counting: Keeping Stock Levels in Check

The Crucial Role of Inventory Audits and Cycle Counting

Step into the critical practice of maintaining optimal warehouse stock levels, where regular inventory audits and cycle counting become indispensable tools. In the intricate dance of warehouse management, these practices are not just routine checks but strategic exercises that ensure the accuracy of your stock levels.


Implementing Systematic Cycle Counts

Embrace the continuous vigilance of cycle counting, which varies from daily to monthly routines based on your warehouse’s unique needs. By employing the ABC analysis method, you focus on counting fast-moving and high-value items more frequently, ensuring a tight grip on your most critical stock. Remember, cycle counts are designed to maintain ongoing accuracy, allowing you to catch and rectify discrepancies promptly rather than waiting for an annual stocktake.


Minimising Disruptions with Targeted Counts

Opt for cycle counts to minimise operational disruptions. Unlike traditional physical inventory counts that often require halting manufacturing and shipping, cycle counts offer a less intrusive yet equally effective alternative. Focus on specific areas or bins regularly, spreading the task across your team. This approach maintains daily operations and ensures a comprehensive count of all items by year’s end.


Setting up a Systematic Approach for Cycle Counts

Systematize your cycle counting process. Allocate specific bins or areas to be counted daily, weekly, or monthly, depending on their importance and turnover rate. Utilise warehouse management software or custom reports to streamline this process. For example, you can create a report in your management system that prompts for specific bins, allowing the counter to focus only on selected areas each day. This targeted approach ensures that errors are identified and addressed swiftly, maintaining a consistently accurate stock level.


Cycle Counting as a Collaborative Effort

Involve your entire team in the cycle counting process. Distribute responsibility among different team members, making it a collaborative effort. Provide clear guidelines and training on how to conduct counts accurately and efficiently. Regular participation from various team members keeps everyone informed about inventory status and fosters a sense of collective responsibility for stock accuracy.


Regular Reviews for Continuous Improvement

Lastly, conduct regular reviews of your audit and cycle counting processes. Analyse their effectiveness, identify recurring issues, and adjust your strategy accordingly. This continuous improvement approach ensures that your methods remain relevant, efficient, and effective in maintaining optimal stock levels in your warehouse.

Effective Supplier Management: Streamlining Restocking

Robust relationships with suppliers aren’t just beneficial but essential for a seamless restocking process. Think of your suppliers not just as vendors but as vital partners in your business’s success.


Beyond Cost: Choosing Suppliers Wisely

When selecting suppliers, look beyond the price tag. Consider factors like service quality, responsiveness, and support capabilities. An ideal supplier is more than just a source of goods; they are collaborators who can offer integration assistance and responsive support.


Establishing Long-Term Agreements

Forge a mostly permanent relationship with your suppliers through Master Services Agreements (MSAs). In these agreements, clarify pricing terms and conditions explicitly. For instance, set specific mark-ups for different categories of products, such as laptops at cost plus 3% or accessories at cost plus 2%. Nail down logistics details like shipping responsibilities and return policies, ensuring no surprises down the line.


Prioritising Service and Support Over Price

Choose suppliers who offer comprehensive services and products, which can lead to better pricing and simplified vendor management. But remember, the lowest price isn’t always the best choice. Evaluate support contracts, Service Level Agreements (SLAs), and the supplier’s ability to scale with your company’s growth. Assess the value of resources and support they provide against the cost.


Making Strategic Decisions in Supplier Selection

Consider the overall value a supplier brings. For instance, if two vendors offer similar products but one has better stock availability or a superior support contract, they may be the better choice despite a higher price. Downtime due to backorders or delayed support can be far more costly than a slightly higher upfront cost.


Leveraging Supplier Relationships for Optimal Pricing

While the best pricing is often reserved for larger customers and bulk orders, don’t hesitate to negotiate with your suppliers. Sometimes, you can piggyback on larger orders to secure better pricing. The key is maintaining open communication and mutual understanding with your suppliers, ensuring that both parties benefit from the partnership.


Consolidating Suppliers for Efficiency

Aim to consolidate your vendors and suppliers where possible. This simplifies your supply chain and billing and strengthens your negotiating position. A supplier that provides multiple services or products under one umbrella can offer enhanced efficiency and potentially better terms due to the larger volume of business.
