No bad vendor file reaches your systems. Ever.
VendorGate validates every external data feed, CSV, Excel, API, or database, against a contract before it reaches your ERP, warehouse, marketplace, or BI tool. Catch format changes, missing rows, and corrupt data before they become production incidents.
Free access during beta. No credit card required.

What is vendor file validation?
Vendor file validation is the practice of checking every file, feed, or extract that arrives from an outside supplier or partner before it is loaded into your internal systems. It ensures that headers, columns, data types, value ranges, and row counts match what your downstream systems expect, so bad data never reaches production.
VendorGate automates this process with contracts. Instead of writing custom scripts for every feed, you define the rules once and the platform enforces them on every run.

The problem
Vendor files fail silently. Your systems pay the price.
External data feeds change without warning. A vendor drops a column. A delimiter changes. A file arrives half empty. By the time your downstream system throws an error, the damage is already done. Stockouts, incorrect pricing, failed marketplace listings, or hours of engineering cleanup.
Format changes
Headers, delimiters, and encodings change without notice, breaking your parsers.
Missing or corrupt rows
Partial uploads, duplicate files, and truncated rows pollute your production data.
Late detection
Issues are discovered after downstream systems have already processed the bad data.

The solution
A contract-driven gate between your vendors and your systems
Validate
Define schemas, rules, statistics, and anomaly thresholds in a contract. Every record is checked before it moves forward.
Decide
Every run gets a clear PASS, REVIEW, or FAIL decision based on findings, severity, and your configured policies.
Route
Valid files are delivered to production. Bad files are quarantined. Edge cases wait for human approval.
How it works
Set up your first gate in minutes
Connect the source
SFTP, FTP, S3, API, or database. Point VendorGate at where the vendor file lives.
Define the contract
Set schema, rules, statistics, and anomaly thresholds that define valid data.
Run validation
The streaming engine checks every record without loading the full file into memory.
Get a decision
Each run produces a PASS, REVIEW, or FAIL based on your configured policies.
Deliver or quarantine
Valid files move to their destination. Bad files are stopped and alerted on.
Features
Everything you need to trust your incoming data
Contract builder
No-code rules for structure, types, values, uniqueness, and cross-field checks.
Streaming validation engine
Go-powered, constant memory usage, no file size limits.
Anomaly detection
Baseline your data and flag volume drops, spikes, and distribution shifts.
Delivery routing
Send valid files forward, quarantine bad ones, hold edge cases for review.
API health monitor
Know when a vendor endpoint goes down before your pipeline does.
File standardizer
Map, join, and normalize files from multiple vendors into one output.
Audit trail
Every run, finding, and decision is recorded and searchable.
Smart alerts
Email and webhook notifications on pass, review, fail, or source unavailability.
Encrypted credentials
AES-256-GCM encryption for all connection credentials, never exposed after creation.
Use cases
Built for any team that receives business-critical data
Distribution and wholesale
Validate daily inventory and pricing feeds from suppliers before they hit your ERP. Catch missing SKUs, price outliers, and duplicate rows before they reach your buyers.
E-commerce and marketplaces
Stop broken product catalog uploads from corrupting your storefront. Ensure every listing has the required images, descriptions, and pricing before going live.
Manufacturing
Ensure supplier component data meets your specs before it enters production systems. Catch unit mismatches, missing part numbers, and invalid certifications.
Logistics and 3PL
Catch incomplete shipment manifests and ASN files before they reach your WMS. Validate weights, dimensions, and tracking numbers at the gate.

FAQ
Frequently asked questions
- What is vendor file validation?
- Vendor file validation is the practice of checking incoming files from suppliers, partners, or marketplaces against a published contract before the data reaches your systems. It ensures the structure, content, and quality of the file are acceptable.
- What file formats does VendorGate support?
- VendorGate supports CSV, Excel, JSON, XML, fixed-width files, REST API payloads, and database query results. All formats are normalized before the same contract rules are applied.
- Can I start using VendorGate for free?
- Yes. The free tier includes one active pipeline, one active contract, one active standardizer, and one API monitor. It is designed for a single proof-of-concept or a small integration.
- How does VendorGate compare to custom Python scripts?
- VendorGate replaces brittle scripts with reusable, no-code contracts. Your team gets an audit trail, anomaly detection, and delivery routing without maintaining code.
- Is VendorGate suitable for enterprise use?
- Yes. The Enterprise plan is designed for organizations with custom source, validation and delivery needs. It includes custom source and delivery connectors, custom contract rules and validations, an optional dedicated instance with custom domain, white-labeling, priority support and onboarding, and annual billing with volume pricing.
