Fivetran is ELT: its SFTP connector pulls files from a source on a schedule and loads them into the destination warehouse. The connector is only as good as the source behind it — and partner files rarely arrive clean. Different senders, different formats, different schedules, no audit trail, and nobody owning the part where the file lands before Fivetran ever reads it.
Files.com is that source. Partners and upstream systems send to your Files.com site over SFTP, FTPS, or HTTPS; an Automation validates each file, normalizes the format Fivetran expects, and stages it where the connector reads. The Fivetran SFTP connector then pulls the clean data and syncs it into your warehouse. Where Fivetran prefers an S3 source, Files.com exposes an S3-compatible API to point at instead — and every file the connector touched is logged.
