For small businesses, monthly services are a great way to keep
costs low. They can be add-ons to an existing business model or a primary means of sales. For many, the Web has erased the trouble of owning and operating a brick-and-mortar store.
Monthly subscriptions are a more efficient way of selling goods. Merchants can count on a certain amount of revenue each month, but they also have better control over inventory. They know ahead of time how much material to purchase each month. Club-of-the-month models also let merchants zero-in on certain types of goods to sell rather than offering a wide array of different items. In most cases, the seller picks the item to send to the client.
