You can use matrix subtraction to prepare the Order.  The matrix addition is used for updating stock with the supplies. Transpose is used for column and row matrices. You can use matrix multiplication to get total cost, total profit for one retail stores or all retail stores together.

Matrices provide efficient method because large number of products and large number of shops can be handled in a compact manner. Manual methods for individual products will be difficult and error prone. It is efficient because same operation is done for all elements in one row. Optimized methods and programs are available. It is easy to identify quantities according to row or column.

Let A be the matrix of current stock. This is maintained by
Let B be the matrix of supplies.

Products is a 1 x 1500 matrix.  Let Np = 1500

RetailStoresList is a 60 * 1 matrix. Let Ns = 60.

Stock is a 1 * Np matrix at one stores.

Stock at all Stores is a Ns * Np matrix: Each row represents stock at one RetailStores.

AllStoresStock =

As the products are sold at one stores, the OneStoreStock is updated. You can have a matrix with threshold values for each product. If quantity goes below this value, then that product is ordered from the head office. This matrix could be same for all retail stores.

ThresholdStock =

OrderStock is again of the same size.
OrderStock =

Now the head office combines all these orders and could prepare combined matrix. This is 60 * 1500 size.

TotalOrder=

If the prices of the products is maintained as Np * 1 = 1500 * 1 matrix then

Prices =

TotalCost = TotalOder x Prices
The TotalCost matrix is a Ns * 1 matrix with each entry for one stores at one locality.

When supplies arrive, the supply matrix could be

TotalSupply=

AllStoresStock = AlStoresStock + TotalSupply
