The objective of this assignment is to develop a national online OSS to provide electronic investor services to domestic and foreign investors. These services shall entirely be automated, paperless, and cashless. Specifically, all services shall be requested and rendered electronically via an online platform; all required supporting documents shall be transmitted, stored, and processed in electronic format; all applications shall be signed electronically; and all required official payments shall be made electronically in real time. The OSS shall be owned, operated, and regulated by BIDA. Its implementation shall adopt a service-oriented architecture that allows it to interface with already existing independent electronic systems of other participating agencies. The OSS shall ultimately serve as a single window and the only point of contact between the Government of Bangladesh and investors.
