What is Duplicate Submission?

Last updated 2026-10-22

Short answer

A duplicate submission happens when the same candidate is submitted to the same requirement more than once, often through different vendors.

Duplicate Submission is a term you will meet constantly in IT staffing. This page explains what it means, how it appears in postings and emails, how a staffing team uses it and the mistakes to avoid.

In practice

Clients and managed service providers often reject a candidate submitted by more than one vendor, and may refuse to consider them for that role.

Duplicates usually come from poor visibility into who has already submitted and from long vendor chains.

How it shows up

Two vendors both send the same Java developer to the same client portal for the same requirement, and the portal flags both.

How a staffing team uses it

Check your submission record before submitting, confirm the end client, and use a right to represent so there is a record of who is authorized.

Common mistakes

  • Not checking before submitting.
  • Marketing the same consultant broadly with no record.
  • Assuming vendors will sort it out.
