VendorFileWatch: The night watch for vendor file deliveries

Monitor scheduled files from vendors and partners, alert on late, missing, or malformed deliveries

Problem

Teams relying on daily CSV, XML, or Excel files from vendors often face late arrivals, no-shows, or files that arrive with wrong fields and formats. They resort to manual morning checks.

Solution

A lightweight file monitoring service. Register expected file sources and format rules, and it automatically checks if files arrive on time and match the expected schema. Alerts via email, Slack, or webhook, plus a daily arrival rate dashboard.

Users

Finance, operations, and data engineering roles that depend on external file exchanges

MVP

Monitor file arrivals from S3, SFTP, email attachments, and HTTP endpoints; configure arrival time and frequency rules; basic CSV/JSON schema validation; email and Slack alerts; simple arrival history dashboard.

Revenue

Monthly subscription with tiered pricing by number of monitored file sources; free tier limited to 2 sources.

Why now

File-based exchanges between businesses remain widespread, yet monitoring tools target APIs, not files. Indie developers can win with no-code setup.
