A B2B file transfer is when businesses exchange files between each other, most commonly through a secure version of a file transfer protocol (FTP) server. This method can be used to move structured data such as invoices, shipping notices or inventory reports in a secure and efficient manner. FTP servers support various secure protocols like FTPS and SFTP, which add layers of encryption and authentication to protect sensitive information during transmission.
These systems function as dedicated endpoints that allow businesses to upload, store and retrieve files. These files are then sent from an internal network to the FTP server, then through an external network, before reaching the final destination of the trading partner’s internal network. Common B2B file transfer use cases include exchanging data with suppliers, customers and third-party partners, which can be called trading partners under an electronic data interchange (EDI) model.
Different industries will have different requirements for the security level and format of B2B data transfers, which may include protocols like OFTP, AS2, HTTPS, SFTP and more. Security mandates may include FIPS 140-2 compliance, PGP or other encryption requirements.

Key aspects of B2B file transfers
B2B file transfers empower businesses to safely share data with other organizations. These transfers often support high data volumes, specific structured data formats and the requirement that they align with regulatory standards and internal policies.
Other key aspects of B2B file transfers include:
- Ability to accept and confirm receipt of structured data in various formats
- Audit and logging trails for tracking file activity
- Integration with internal systems for automation
- Role-based access and authentication controls
- Support for large and recurring file transfers
- Use of secure protocols like SFTP or FTPS
Benefits of using MFT for B2B file transfers
Managed file transfer (MFT) tools are designed to handle repetitive transfers, protect sensitive files and support integration with internal tools and workflows. Transferring data using an MFT solution can provide your organization structured, secure and automated methods for moving data between its systems.
Other benefits of using MFT for B2B file transfers are:
- Automated workflows for consistent operations
- Centralized control over file activity and access, such as the enforcement of file retention policies
- Detailed logging for audits and compliance
- Encrypted transfers to reduce exposure risk and demonstrate compliance
- Protocol support for interoperability across systems
How B2B file transfers work
B2B file transfers follow a structured process that allows your organization to exchange files through secure and automated protocols. These transfers often rely on scheduled workflows, authentication policies and encrypted channels to ensure data is transferred to the correct destination without manual intervention.
The B2B file transfer process involves:
- Creating a trading partner or user within your file transfer server
- Authenticating those users or systems with credentials or keys
- Establishing a connection using SFTP, FTPS or another supported protocol
- Uploading or downloading files through a secure session
- Logging file activity for auditing or troubleshooting
- Triggering post-transfer actions, such as processing or archiving
- Generating a receipt acknowledgement to the sending server
Common B2B file transfer protocols
B2B file transfers depend on secure and standardized protocols to move data internally and externally between organizations. Each protocol offers different features related to security, compatibility and control. Selection depends on business requirements, compliance needs and system capabilities.
Some B2B file transfer protocols are:
- AS2: Sends EDI data securely over HTTP with digital signatures
- FTPS: Adds TLS encryption to traditional FTP and is mostly commonly used for legacy systems
- HTTPS: Transfers files over the web with SSL/TLS security
- SFTP: Uses secure shell (SSH) for encrypted file transfer and authentication
- OFTP2: Uses EDI for transmission, especially in the automotive and manufacturing industries
MFT in B2B operations
MFT plays a key role in B2B operations by providing a secure automated framework for exchanging files across systems and organizations. MFT platforms are built to handle large-scale, recurring transfers with the precision and auditability required for business compliance.
Ways to use MFT in daily B2B operations include:
- Automating financial data transfers to external partners
- Distributing product or pricing files to retailers
- Exchanging EDI documents with suppliers or customers
- Moving compliance-related reports to auditors or regulators
- Sharing operational data with logistics or manufacturing systems
Enterprise file transfer vs. enterprise file sharing
Enterprise file transfer and enterprise file sharing serve different purposes within an organization. File transfer is typically used for automated, system-to-system data movement, while file sharing focuses on user-driven collaboration. Both play roles in business workflows but have distinct technical and security requirements.
There are key differences between enterprise file transfer and file sharing.
File transfer:
- Integrates with internal systems for scheduled jobs
- Prioritizes compliance, encryption and audit trails
- Uses protocols like SFTP or AS2 for automation
File sharing:
- Relies on web interfaces or synced folders
- Supports version control and user permissions
- Uses various methods like cloud services and network drives

File transfer FAQs
There are three main types of file transfer: FTP, SFTP and FTPS. FTP is the oldest method. It sends files in plain text and does not use encryption. SFTP runs over SSH and encrypts both commands and data. FTPS uses SSL or TLS to encrypt the FTP session.
SFTP and FTPS are common when security or compliance matters. FTP is still used in internal systems without strict encryption needs. All three support large files, automation and scheduled workflows. Their encryption types and port settings are different. The best choice depends on your company’s needs and IT setup.
SFTP and HTTPS are both widely used for transferring files over the internet. HTTPS and API-based transfers are most common. These are often used in cloud settings and for connecting to web services. HTTPS is popular for B2B transfers. It supports modern login methods. It works well with firewalls, and it is often used in automated systems or application workflows.
SFTP runs over SSH. It encrypts data during transfer. It allows other login options beyond usernames and passwords. It is often chosen for B2B data sharing. It offers strong security, and it works across many systems. SFTP is simple to set up.
