11 Inventory Management Techniques For Tanzania Entrepreneurs

I used to dread the word “inventory.” As a part-time cashier in high school, the word meant only one thing: lots and lots of counting. It’s common for businesses to reconcile their inventory at the end of the year by counting all their physical stock and making sure it matches what’s on the books. For big companies like the one I used to work for, this requires everyone’s help.
These days, I understand just how important solid inventory management is. Inventory is a placeholder for money. You paid money for your inventory, and you’ll get that money back (and then some) when you sell it.
Holding inventory ties up a lot of cash. That’s why effective inventory management is crucial for growing a company. Just like cash flow, it can make or break your business.

What is inventory management?

Inventory management is the act of keeping track of your ecommerce company’s stocked goods and monitoring their weight, dimensions, amounts, and location. The goal of inventory management is to minimize the cost of holding inventory by helping business owners know when it’s time to replenish products or buy more materials to manufacture them.

What is inventory control?

Inventory control can be used interchangeably with inventory management. Essentially, it refers to when you have control over your stock, typically due to effective inventory management processes. It’s much easier to maintain control of your inventory with centralized inventory management.

Why inventory management is important

Effective inventory management is essential for ensuring a business has enough stock on hand to meet customer demand. If inventory management is not handled properly it can result in a business either losing money on potential sales that can’t be filled or wasting money by stocking too much inventory. Inventory management also helps your business in a number of other ways.

Inventory management saves you money

1. Avoid spoilage

If you’re selling a product that has an expiry date, like food or makeup, there’s a very real chance it will go bad if you don’t sell it in time. Managing inventory effectively helps you avoid unnecessary spoilage.

2. Avoid dead stock

Dead stock is stock that can no longer be sold but not necessarily because it expired—it could have gone out of season, out of style, or otherwise become irrelevant. By adopting a diligent strategy, you can address this costly inventory mistake.

3. Save on storage costs

Warehousing is often a variable cost, meaning it fluctuates based on how much product you’re storing. When you store too much product at once or end up with a product that’s difficult to sell, your storage costs will go up. Avoiding this will save you money.

2. First in, first out (FIFO)

First-in, first-out (FIFO) is an important principle of inventory management. It means your oldest stock (first in) gets sold first (first out), not your newest stock. This is especially important for perishable products so you don’t end up with unsellable spoilage.
It’s also a good idea to practice FIFO for non-perishable products. If the same boxes are always sitting at the back, they’re more likely to get worn out. Plus, packaging design and features often change over time. You don’t want to end up with something obsolete that you can’t sell.
In order to manage a FIFO system, you’ll need an organized warehouse. This typically means adding new products from the back or otherwise making sure old product stays at the front. If you’re working with a warehousing and fulfillment company, they probably do this already, but it’s a good idea to confirm.

3. Manage relationships

Part of successful inventory management is being able to adapt quickly. Whether you need to return a slow-selling item to make room for a new product, restock a fast seller very quickly, troubleshoot manufacturing issues, or temporarily expand your storage space, it’s important to have a strong relationship with your suppliers. That way they’ll be more willing to work with you to solve problems.
In particular, having a good relationship with your product suppliers goes a long way. Minimum order quantities are often negotiable. Don’t be afraid to ask for a lower minimum so you don’t have to carry as much inventory.
A good relationship isn’t just about being friendly. It’s about clear, proactive communication. Let your supplier know when you’re expecting an increase in sales or generating a lot of purchase orders so they can adjust production. Ask them to notify you when a product is running behind schedule so you can pause promotions or look for a temporary substitute.

4. Contingency planning

A lot of issues can pop up related to inventory management. These types of problems can cripple unprepared businesses. For example:

  • Your sales spike unexpectedly and you oversell your stock.
  • You run into a cash flow shortfall and can’t pay for product you desperately need.
  • Your warehouse doesn’t have enough room to accommodate your seasonal spike in sales.
  • A miscalculation in inventory means you have less product than you thought.
  • A slow-moving product takes up all your storage space.
  • Your manufacturer runs out of your product and you have orders to fill.
  • Your manufacturer discontinues your product without warning.

It’s not a matter of if problems arise, but when. Figure out where your risks are and prepare a contingency plan. How will you react? What steps will you take to solve the problem? How will this impact other parts of your business? Remember that solid relationships go a long way here.

5. Regular auditing

Regular reconciliation is vital. In most cases, you’ll be relying on software and reports from your warehouse to know how much product you have in stock. However, it’s important to make sure the facts match up. There are several methods for doing this.

Physical inventory

A physical inventory, or stock take, is the practice of counting all your inventory at once. Many businesses do this at their year end because it ties in with accounting and filing income tax. Although physical inventories are typically only done once a year, it can be incredibly disruptive to the business, and believe me, it’s tedious. If you do find a discrepancy, it can be difficult to pinpoint the issue when you’re looking back at an entire year.

Spot checking

If you do a full physical inventory at the end of the year and you often run into problems, or you have a lot of products, you may want to start spot checking throughout the year. This simply means choosing a product, counting it, and comparing the number to what it’s supposed to be. This isn’t done on a schedule and is supplemental to physical inventory. In particular, you may want to spot check problematic or fast-moving products.

Cycle counting

Instead of doing a full physical inventory, some businesses use cycle counting to audit their inventory. Rather than a full count at year end, cycle counting spreads reconciliation throughout the year. Each day, week, or month a different product is checked on a rotating schedule. There are different methods of determining which items to count when but, generally speaking, higher-value items will be counted more frequently.

6. Prioritize with ABC

Some products drive more revenue than others. You can use an ABC analysis report to grade the value of your stock based on a percentage of your revenue:

  • A = % of stock that represents 80% of your revenue
  • B = % of stock that represents 15% of your revenue
  • C = % of stock that represents 5% of your revenue

Therefore, your A stock represents your most profitable and valuable products. You’ll want to make sure you always have these products on hand so you don’t miss out on future sales. Your C stock is your slow-moving or dead stock. This is stock you might want to sell at a discount, so you can get it off your shelves and free up cash from your inventory.

7. Accurate forecasting

A huge part of good inventory management comes down to accurately predicting demand. Make no mistake, this is incredibly hard to do. There are countless variables involved and you’ll never know for sure exactly what’s coming—but you can try to get close. Here are a few things to look at when projecting your future sales:

  • Trends in the market
  • Last year’s sales during the same week
  • This year’s growth rate
  • Guaranteed sales from contracts and subscriptions
  • Seasonality and the overall economy
  • Upcoming promotions
  • Planned ad spend

If there’s something else that will help you create a more accurate forecast, be sure to include it.

8. Last in, first out (LIFO)

The last in, first out, or LIFO, inventory management method assumes that the merchandise you acquired most recently was also sold first. The last to be bought is assumed to be the first to be sold. It’s essentially the opposite of FIFO.
This works under the assumption that prices are steadily rising, so the most recently purchased inventory will also be the highest cost. That means that higher costs will yield lower profits, and, therefore, lower taxable income—this is pretty much the only reason it makes sense to use LIFO.
In general, LIFO is a really difficult method to actually use to manage inventory. If you keep your oldest merchandise on the back of the shelf, it’s more likely to become obsolete and unsellable at a certain point. This rings true for both perishables and non-perishables. Items can get damaged, worn, and outdated.

9. Just-in-time (JIT)

Just-in-time, or JIT, inventory management is for the risk takers out there, though effective inventory management mitigates a lot of that risk. With JIT, you keep the lowest inventory levels possible to still meet demand and replenish before a product goes out of stock.
This requires careful and accurate planning and forecasting, but works well for rapidly growing brands with calculated launches and product line extensions.

10. Safety stock

Safety stock is like an emergency fund—it’s basically inventory you “set aside” for use in case of emergency. It acts as more of a threshold for when you need to reorder merchandise before dipping into your emergency stock allocation.
Safety stock has a formula:

Safety Stock = (Maximum Daily Usage x Maximum Lead Time) – (Average Daily Usage x Average Lead Time)

It’s a good idea to work safety stock into your inventory management strategy in case your supply chain is disrupted, your merchandise is damaged, or some other unforeseen circumstance prevents your ability to receive or manage merchandise.

11. Reorder point

The reorder point tells you the level at which it’s time to replenish your stock. Once you know your safety stock level, you can consider lead time with your supply chain to determine the ideal point at which it’s time to place your order.
You can use the following formula to calculate the reorder point in your business:

Reorder Point = Lead Time Demand + Safety Stock

Calculating reorder points is vital for effective stock management, but it can be incredibly time consuming when dealing with a large number of products. A powerful inventory management system makes it a lot easier.

An inventory management system can work for a small business

While many small businesses start out with the old-school pen-and-paper method, this gets unwieldy quick—especially if you have growth goals. Not to mention it makes you more vulnerable to human error, which can lead to costly business mistakes.
When you use a powerful inventory software to help you track stock, you get access to benefits like stock alerts, automated purchase orders, year-end inventory reporting, and user permissions and accounts. Combined, inventory tracking software features give you complete control and insight into your business and how inventory moves from suppliers to customers and everywhere in between.
