The goal of inventory management is to keep up with demand, and this means that you will need enough inventory to meet whatever your projected sales are. If you have been in business for a period of time, you can use historical sales to predict approximately what your future sales will be. If you are new, you will want to base your sales forecast on the type of business you are, your location, other similarly sized businesses in your region/industry, and on any contracts or customers you have already secured. You will want to look at how much each type of product sells on a monthly basis, and ensure you order enough inventory to cover this amount plus some extra inventory in case there is more demand than expected. How much extra you order depends on the nature of your business. Is your business prone to rapid increases and decreases in demand? If so, you may want to keep extra inventory to be cautious. How much stock you keep and how much you order depends on your level of sales, the type of stock, and how much space you have available. If your inventory consists of perishable items or if you have low levels of space, you will want to look at your previous sales data and ensure you have slightly more than that to meet projected demand plus any potential growth. Inventory management is very important if you have little space or perishable items, and you want to closely monitor levels to be sure you do not run out. You always want to choose reliable suppliers who can get you your inventory quickly and on-time. If you have a trustworthy delivery company for your stock and they are able to deliver frequently, you can reduce your back stock. If your items are not perishable and if you have the space, you can consider taking advantage of bulk discounts by purchasing more inventory. This is a useful approach if your sales are hard to predict, if they fluctuate heavily, and if your products are not in a market where preferences change rapidly. Another factor to keep in mind is how quickly your items can be delivered to you after you order them. For instance, if it takes a week for your order of a certain item to be delivered, then you will likely want to order larger quantities of the item to have on-hand so you don't run out while you wait for the next delivery. If, however, items can be delivered the next day, then you know you can quickly replenish dwindling inventory and don't need to keep as much backstock. Your goal is to always have enough inventory to meet customer demand, while not carrying too much inventory, as this ties up your capital unnecessarily. To make sure you have the right level of stock at all times, you need to know when to re-order. One approach is to specify a minimum level of stock, at which point you always re order. For example, you would never let your supply of shirts fall below 100. As soon as it does, a re-order occurs. This ensures you never run out. For products that move quickly, or have the potential to move quickly set a higher minimum level. If you are a seasonal business, you may want to increase this minimum level for a few months around the time of year that you see a seasonal boost. For instance, if you carry items that are primarily cold weather items, carry more of specific items needed in case of big winter weather events. This safety (or buffer) stock will prevent shortages that could occur between when you place an order and when you receive it. The amount of safety stock you have should depend on how prone your business is to rapid changes in demand, as well as the time of year if you are a seasonal business. This is especially helpful if you are a large retailer or need a good inventory count for year-end or for the end of a big sale season. The agency will count your full stock, write the reorder and even removed unwanted merchandise to send back to the manufacturer per a predetermined arrangement with your company.

A school pencil will give you a good medium shade line and a medium width of the line. If you want a darker pencil use a B pencil. Most craft and art stores sell drawing pencils. The best drawings use a variety of pencil shades. The higher the number, the darker you can go. For example, 6B is much darker than 2B. If you want a really light line use an H pencil. The higher the number the lighter the line. For example, 6H is much lighter than 2H. The sharper the point, the better you can draw. Sharpen it often as you draw. The "tooth" of a paper is how rough and textured the surface is. Paper that is rougher, with a higher tooth, will collect more graphite for deeper shading, but the texture will show through and it may be difficult to add details and polish to your art. Paper that is very smooth, like Bristol board, will make for a cleaner looking finished product and an easier time adding small detail. However, it may make it impossible to get darker shades without "burnishing" the graphite. Burnishing comes from smoothing the surface of the paper with the pressure of the pencil until it becomes reflective and appears light rather than very dark. If this is a problem for you, choose softer pencils and don't press down as hard. This prevents smudges and stains. If you get up to grab a snack, wash your hands again before getting back to your drawing. Never rest any part of your hand on any part of your paper that has pencil on it. In other words never rest your hand on your actual drawing. Try to keep your hand on the blank parts of the paper. This prevents blurring your lines. Lay a piece of scrap paper between your hand and the art if you need to work on an area that isn't near any blank space. Wear gloves. This way, you don't have to worry as much about washing your hands. You can use gloves that only cover half of your hand and are designed for drawing.

Geckos should be supplied with a dish of water that they can drink. Make sure that the water is replaced and the dish cleaned on a regular basis, ideally every day. Provide tap water treated with Reptisafe, tap water left out for 24 hours, or spring water. Never distilled as this lacks minerals. If your tap water doesn't contain chlorine (which is the case in countries such as the United Kingdom and Germany)it can be given to your gecko as it is. This water should not be very deep, so that there is little chance of the gecko drowning in it.
