a fertilizer shop, of course, it must have the stock of goods that farmers want so
that there is a necessity for fertilizer shops to meet fertilizer needs. Due to
frequent loss sales due to insufficient stock of goods due to shop owners still using
conventional methods. Therefore, a calculation is made to increase sales with the
EOQ method so that the store can increase sales and reduce store inventory costs.
