An economy is competitiveness is driven by many factors, including how quickly reliably and cost-effectively the private sector can trade good. Today is manufacturers and agricultural producer operate in a global supply chain. Thus an efficient international trad system can increase economic opportunities and improve livelihoods-especially in poor economies with small domestic markets But in many part of the world, international traders must spend a lot of time preparing and submitting information to government offices ranging from customs to port authorities, each with its own rules and form requirement. These reporting requirements are often confusing, overlapping and onerous. In madagascar the government offices involved in trade span 350 kilometers, and hard copies of form had to be submitted to each untill and electronic platform introduced in 2011 transformed the document submission process and reduced delays ( see the chapter on trading across borders). A single window system can improve information flows by sharing needed information with all parties involved in trade, including private participants such as banks and insurance companies and public agencies such as immigration and vehicle registration authorities. The key concept for an effective system is to enable traders to submit standardized information and documents through a single geatway, eliminate redundant processes by traders and government agencies and improve coordination and cooperation between authorities. Reducing multiple data submissions to different agencies helps minimize errors during data entry too.Single window systems have other benefits. One that collects data systematically enables consignments to be categorized more easily based on the associated risk by allowing creation of trader profiles limiting physical inspections to risky cargo and potentially making trade procedures more secure and efficient. By combining a portal where up-to-data information on tariffs and other legal and procedural requirements are available and by integrating a payment system,duties and other charges can be paid more quickly and accurately, raising government revenues.
