Open Up Office | Virtual Office, Serviced Offices and Secretariat Services

Operating in Istanbul’s business district of Kadıköy Kozyatağı since 2011, Open Up Office (legally incorporated as Yeke Ses ve Organizasyon Hizmetleri Tic. Ltd. Şti.) provides flexible workspace solutions, registered legal address options, and professional business support services. Positioned on the Anatolian side of Istanbul, the organization caters to a dynamic community ranging from early-stage entrepreneurs and independent practitioners to established corporate companies and multinational enterprises.

Over more than a decade of operation, Open Up Office has delivered corporate address and office solutions to more than 2,000 entities. The community includes software and technology enterprises, legal practitioners, medical professionals, chartered certified accountants, charitable foundations, business management advisors, and fast-growing startups. Situated within the Hamdiye Yazgan Business Center, the facility offers immediate access to the E-5 highway and metro transit lines.

Virtual Office and Legal Address Solutions

For businesses registering a new legal entity or relocating an existing operation, Open Up Office provides formal commercial addresses compatible with the Trade Registry and local tax office requirements. The virtual office model significantly reduces overhead costs associated with conventional commercial leasing—such as real estate agent commissions, heavy deposits, fixture expenses, and building dues. Invoices are issued with VAT rather than withholding tax (stopaj), delivering direct accounting benefits. Virtual address activation is completed within 24 to 48 hours of documentation submission.

Virtual office plans are categorized into tiered service levels:

• Standard Plan: Supplies the registered company address, mail and package handling, and official administrative notice processing.
• Plus Plan: Encompasses all Standard services alongside customized corporate phone answering, dedicated secretarial assistance, and 2 hours of monthly meeting room access.
• Premium Plan: Extends Plus coverage by including 4 hours of monthly meeting room access as well as 8 hours of coworking space utilization each month.

Secretarial Support, Call Handling, and Call Center Solutions

Open Up Office provides dedicated phone lines answered in each client’s registered commercial name. Dedicated personnel follow defined instructions to either seamlessly patch incoming callers through to designated mobile lines or summarize inquiries via instant email notifications. Voice recording capabilities and swift communication channels ensure zero missed inquiries. Additionally, comprehensive inbound and outbound call center services are integrated into client CRM systems to enhance customer outreach and daily management efficiency.

Furnished Serviced Offices and Coworking

For teams needing fully equipped physical space, Open Up Office provides ready-to-use private offices alongside adaptable coworking desks. These spaces feature modern office furniture, high-speed networking infrastructure, and shared lounge amenities. Fully configured meeting rooms are available for client consultations, team sessions, and stakeholder meetings, offering a professional business setting on an on-demand basis.

Digital Member Portal and Administrative Compliance

A proprietary online client portal allows members to monitor received mail, review correspondence logs, check incoming package notices, and manage invoices securely in one place. During statutory tax office field inspections (yoklama), on-site team members represent the location, ensuring smooth completion of official verification procedures. All data management, administrative support, and call operations strictly align with data protection and privacy standards under KVKK.
