Abought ledgeris a system inaccountingby which a business records and monitors itscreditors. The purchase ledger contains the individual accounts of suppliers from whom the business has made purchases oncredit. Information oninvoicesandcredit notesreceived, and payments made, are recorded in the supplier's account using thedebits and creditssystem, with thebalanceof each account at a given moment representing the amount currently owed to that supplier.
Historically, the purchase ledger was maintained in book form, hence the termledger, but in modern practice it is much more likely to be held on computer usingaccountancy softwareor aspreadsheet. The concept of Double-entry Bookkeeping is that debits balance the credits at all times. For convenience the main Trial Balance lists some accounts containing many entries as simply a single control figure. There is then a separate physical Ledger for the summarised area, which could conveniently be managed on its own, often at physically separate locations from the main ledger book. The Purchase Ledger is a common example of this.
The purchase ledger will ordinarily be an overall credit (liability) balance, unless credit notes or over-payments exceed the credit balance. However within itself, it is usual to show all invoices as positive figures, and payments as negative entries, as this minimises the number of negative entries to make/read.
Newmarket is a market town in the English county of Suffolk, approximately 65 miles (105 kilometres) north of London. It is generally considered the birthplace and global centre of thoroughbred horse racing and a potential World Heritage Site. It is a major local business cluster, with annual investment rivalling that of the Cambridge Science Park, the other major cluster in the region. It is the largest racehorse training centre in Britain, the largest racehorse breeding centre in the country, home to most major British horseracing institutions, and a key global centre for horse health. Two Classic races, and an additional three British Champions Series races are held at Newmarket every year. The town has had close royal connections since the time of James I, who built a palace there, and was also a base for Charles I, Charles II, and most monarchs since. The current monarch, Queen Elizabeth II, visits the town often to see her horses in training.
Newmarket has over fifty horse training stables, two large racetracks, the Rowley Mile and the July Course, and one of the most extensive and prestigious horse training grounds in the world. The town is home to over 3,500 racehorses, and it is estimated that one in every three local jobs is related to horse racing. Palace House, the National Heritage Centre for Horseracing and Sporting Art, the National Horseracing Museum, Tattersalls racehorse auctioneers, and two of the world's foremost equine hospitals for horse health, are in the town, which is surrounded by over sixty horse breeding studs. On account of its leading position in the multibillion-pound horse racing and breeding industry, it is also a major export centre.
