A guide to managing Contractor of Record (COR)

Multiplier’s Contractor of Record (COR) solution helps you engage, pay, and manage independent contractors compliantly across countries. As an admin, you can use the platform to onboard COR contractors, update their compensation and role, and offboard them when the engagement ends—all while staying aligned with local labor and tax regulations.

Use this guide as your central hub. For each scenario below, there is a brief overview of what you can do in Multiplier and a link to the step‑by‑step article.

Onboard a COR on the Multiplier platform

Use this flow when you’re bringing a new contractor into Multiplier as a COR. You can create a compliant contract, capture KYC details, and set up billing type, pay rate, and payment method in a single workflow. This ensures the contractor is activated on time and all future invoices and payouts flow through Multiplier correctly.

• For a full walkthrough—from adding contractor details to sending the contract and tracking their onboarding status— view Onboard a Contractor of Record on Multiplier.

If you are hiring a large group, you can upload their details in one go instead of creating each profile manually. Bulk onboarding reduces data-entry effort and keeps start dates aligned for the entire group.

Revise compensation and designation for a COR contractor

Over time, you may need to adjust a contractor’s compensation or role—for example, changing the billing rate, updating billing type (fixed vs pay‑as‑you‑go), or updating their title/description for contract accuracy. Multiplier lets you update these details and generate an addendum so changes are fully documented and reflected in future invoices and payouts.

Offboard a COR contractor

When a COR contractor resigns or their contract is terminated, you should use the offboarding flows so that work access, payments, and documentation are handled correctly. Offboarding through Multiplier helps you keep records clean, prevent further billing, and make sure final payouts are processed as per the agreement and local rules.

There are two main scenarios:

1. Resignation – Use this when the contractor has given notice, and you’re ending the engagement by mutual agreement. You’ll capture the last working day, any notice period, and final payments.

For detailed steps, view Offboard a COR contractor who resigned.

1. Termination – Use this when you are ending the engagement from the company side (for performance, project closure, or other reasons). The flow helps you confirm effective dates, applicable pay, and documents.

Manage COR Contractor invoices

Multiplier makes it simple to review and act on all COR contractor invoices in one place. From the Contractor invoices section, you can approve or reject individual invoices, upload multiple invoices in bulk, and download review reports to reconcile what’s been billed versus approved and paid. This helps you keep payouts accurate, on time, and fully auditable.

• To learn how to review, approve, or reject invoices raised by contractors, see Approve or reject contractor invoices.

• To add many invoices at once using a template instead of entering them one by one, see Upload contractor invoices in bulk on Multiplier.

• To verify bulk uploads, track review status, or share data with finance, see Download the contractor bulk invoice review report.

Manage COR Contractor timesheet

Multiplier lets you manage COR contractor timesheets from a single view, so you can ensure billed hours are accurate before they are converted into invoices. You can quickly approve timesheets that look correct, reject incorrect entries with comments, and use approved timesheets to drive invoice creation for COR Contractors.

• To review hours and approve COR contractor timesheets so they move forward for billing, see Approve COR contractor timesheet.

• To send a timesheet back when hours, dates, or details are incorrect—and share the reason with the contractor—see Reject COR contractor timesheet.

Timesheet-based invoicing

Using the Multiplier platform, you can also raise invoices when you approve timesheets.
