Construction differs from manufacturing in that manufacturing typically involves mass production of similar items without a designated purchaser, while construction typically takes place on location for a known client, but may be done speculatively for sale on the real estate market.
Renting is an agreement where a payment is made for the temporary use of a good, service or property owned by another.
Things that can be rented or leased include land, buildings, vehicles, tools, equipment, furniture, etc.
Many phone companies provide pay-as-you-go services whereby the customer only pays for the number of minutes he actually uses.
In the shareware model, users are encouraged to make and share copies of a software product, which helps distribute it.
Payment may be left entirely up to the goodwill of the customer (donationware), or be optional with an occasional reminder (nagware), or the software may be designed to stop working after a trial period unless the user pays a license fee (trialware or demoware), or be crippled so that key features don't work.
Donationware is a licensing model that supplies fully operational unrestricted software to the user and requests an optional donation be paid to the programmer or a third-party beneficiary (usually a non-profit).
[7] The amount of the donation may also be stipulated by the author, or it may be left to the discretion of the user, based on individual perceptions of the software's value.
Nagware is a type of shareware that persistently reminds (nags) the user to register it by paying a fee.
In software, crippleware means that "vital features of the program such as printing or the ability to save files are disabled until the user purchases a registration key".
For example, a fully functional feature-limited ("lite") version may be given away for free, with advanced features disabled until a license fee is paid.
This model characterises wholesalers and retailers, who buy products from manufacturers, mark up their prices, and resell them to end customers.
Wholesaling, jobbing, or distributing is the sale of goods or merchandise to retailers; to industrial, commercial, institutional, or other professional business users; or to other wholesalers and related subordinated services.
Retail is the process of selling consumer goods or services to customers through multiple channels of distribution to earn a profit.
The buyer places an order for the desired products with the merchant through some remote method such as by telephone call or web site.
Some merchants also allow the goods to be shipped directly to a third party consumer, which is an effective way for someone to buy a gift for an out-of-town recipient.
In the 21st century, an increasing amount of retailing is e-tailing, done online using electronic payment and delivery via a courier or postal mail.
