A large pack always looks cheaper at a wholesaler. But the real cost comes from what gets used rather than from the price per kilogram.
What is the advantage of a bulk pack?
The difference in unit cost is real and measurable.
A 3.5-kilogram pack generally costs 8 to 15 percent less than two 1.75-kilogram packs of the same product.
That difference comes from packaging material and filling labour.
The proportion of packaging material falls in a large pack.
Transport is more efficient too; more product travels in the same volume.
The labour of ordering falls as well; fewer lines and fewer goods-in checks.
Shelf arrangement in the store simplifies too.
Those advantages are genuine; but all of them depend on the whole pack being used.
What happens to shelf life after opening?
That is the other half of the decision.
While the pack stays sealed the product's protection system works: vacuum, modified atmosphere or sterilisation.
That protection ends the moment the pack opens.
The product then behaves like any other food.
Sliced deli products keep five to seven days after opening.
Cheese keeps seven to fifteen.
The window is more flexible with frozen product, but ice crystals and freezer burn begin in a pack opened repeatedly.
| Product | Unopened | After opening | At 250 g a day |
|---|---|---|---|
| 1.75 kg deli | The date on the pack | 5-7 days | Empties in 7 days — suitable |
| 3.5 kg deli | The date on the pack | 5-7 days | Empties in 14 days — risky |
| 1.75 kg cheese | The date on the pack | 10-15 days | Empties in 7 days — suitable |
| 3.5 kg cheese | The date on the pack | 10-15 days | Empties in 14 days — marginal |
| 3.5 kg frozen | 12-18 months | 3 months if resealed | Flexible |
How is daily use calculated?
That calculation settles the whole decision.
Daily use gets recorded across a week.
How much of the product goes into every item on the menu gets written down.
Dividing the week's total by seven produces the figure for a single day.
Then a simple division: pack weight divided by daily use.
The result gives the number of days the pack takes to empty.
Where that period is shorter than the product's shelf life after opening, the size is right.
Where it is longer, a smaller pack is needed.
In a business using 250 grams of deli products a day, a 1.75-kilogram pack empties in seven days; a 3.5-kilogram pack lasts fourteen and its second half becomes risky.
How does storage space affect it?
A bulk pack takes less shelf space.
But the situation changes once it opens.
An opened bulk pack has to be transferred to another container.
That requires an extra container and extra shelf space.
Refrigerated space is limited too; fridge capacity is the tightest resource in a small business.
An opened 3.5-kilogram product occupies more cold space than two sealed 1.75-kilogram packs.
Freezer space decides it with frozen product.
Once a large pack opens, all of it stays in the freezer occupying space; smaller packs allow a more flexible arrangement.
What does cash flow change?
That is the factor most overlooked in small businesses.
Bulk buying requires a larger payment up front.
Product sitting in stock means capital tied up.
Cash flow is tight in a small business; every amount tied up postpones another need.
Frequent, small orders carry a higher unit cost but ease cash flow.
That is a measurable balance; where the unit cost difference is 10 percent and stock turnover doubles, the small pack makes more sense in most cases.
Payment terms belong in the calculation too; a bulk purchase on thirty-day terms can beat a small purchase paid immediately.
How is the cost of waste calculated?
That calculation clarifies the decision.
Take an example: a 3.5-kilogram pack at 400 lira per kilogram comes to 1400 lira.
A 1.75-kilogram pack at 440 lira per kilogram comes to 1540 lira for two.
The difference is 140 lira and the large pack looks advantageous.
But where the last 500 grams of the large pack cannot be used, the real cost is 1400 lira divided by 3 kilograms.
That is 467 lira per kilogram, more than the small pack.
The critical point is this: once waste exceeds 10 percent the advantage of a bulk pack disappears entirely.
Waste should therefore be measured; product thrown away over a month gets weighed and recorded, and the decision follows from that data.
How is a mixed strategy built?
That is the most efficient approach for most businesses.
Bulk packs for best sellers.
Those products empty quickly and the risk of waste is low.
Small packs for slow sellers.
Those empty slowly and a large pack creates waste.
The decision gets made product by product against frequency of use on the menu.
Seasonality belongs in the calculation too; where a product empties fast in summer and slows in winter, the pack size can change with the season.
That flexibility is worth discussing with the supplier; most offer the same product in two sizes and changing the size on an order form costs nothing.
How is it discussed with the supplier?
Pack size is a line that can be changed on an order form.
But most businesses choose it once and forget it.
Three subjects belong in a conversation with the supplier.
The first is which sizes the same product comes in; most producers offer two or three.
The second is the price difference between sizes; that gap is sometimes smaller than assumed.
The third is whether mixed orders are possible; some suppliers can send two sizes of the same product together.
That flexibility accommodates seasonal changes in demand.
Delivery frequency belongs in the conversation too; two deliveries a week rather than one makes smaller packs viable and markedly reduces waste.
Those three questions take a single phone call and rarely get asked, which is why pack sizes tend to stay wrong for years.
