Overview
Moving from Team Engine to Bullhorn is a platform switch from a hiring-and-communication-first tool built for blue-collar workforces to a full ATS and CRM built for staffing agencies. Team Engine organizes applicants, employees, and message threads around communication workflows; Bullhorn uses a structured entity model with Candidate, ClientContact, JobOrder, and Opportunity objects that requires each Team Engine record to be mapped individually before import. We extract Team Engine's Jobs and Applicants via CSV export, resolve message threads against the corresponding employee record, and handle Employee Groups as Bullhorn tags. Survey responses and referral history move to Bullhorn custom objects. Workflow triggers and automated message rules are configuration, not data, and cannot migrate; we deliver a written audit of every active trigger for the customer's Bullhorn admin to rebuild manually.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Team Engine object lands in Bullhorn ATS & CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Team Engine
Jobs
Bullhorn ATS & CRM
JobOrder
1:1Team Engine Job records (title, description, location, requirements, posting status, post-date, closing date) map directly to Bullhorn JobOrder. The JobOrder status field maps from Team Engine's posting status. We preserve post-date and closing date as standard date fields on the Bullhorn JobOrder. JobOrder addresses and location data migrate to the JobOrder address fields or to a custom address field depending on the Team Engine export format.
Team Engine
Applicants
Bullhorn ATS & CRM
Candidate
1:1Team Engine Applicant records (name, contact info, application date, status: applied/screening/hired/rejected, source, rejection reason) map directly to Bullhorn Candidate. The application status maps to the corresponding Bullhorn Candidate status or a custom status field. Application date migrates as dateApplied. Source attribution maps to Candidate source field. We flag records with a rejected status so that the customer can decide whether to import rejected candidates as inactive Bullhorn Candidates or exclude them from the initial migration.
Team Engine
Employees
Bullhorn ATS & CRM
Candidate (primary) or ClientContact (for client-facing staff)
1:1Team Engine Employee records (name, contact details, hire date, group membership) map to Bullhorn Candidate by default. For firms where some employees are also client contacts, we map those to ClientContact with a dual-link. Hire date migrates as dateAdded or to a custom hire date field. Group membership maps to Bullhorn tags (see Employee Groups). We validate that each employee record has a unique email or phone before import to avoid Bullhorn duplicate violations.
Team Engine
Employee Groups
Bullhorn ATS & CRM
Tags
lossyTeam Engine Employee Groups (customizable groups by role, shift, location, or trade) map to Bullhorn Tags as string values on the corresponding Candidate or Contact record. Group names are preserved as-is. We flag any group name collisions with existing Bullhorn tags during scoping. If the customer requires group-based filtering in Bullhorn reports, we recommend a custom Candidate field rather than relying solely on tags for organizational hierarchy.
Team Engine
Messages (SMS/WhatsApp)
Bullhorn ATS & CRM
Task or Note
1:1Team Engine message threads are organized by contact phone number, not by employee record. We resolve each thread to the corresponding Bullhorn Candidate or ClientContact by matching the phone number. Thread content migrates as Bullhorn Task records with a custom body field or as Note records linked via ContentDocumentLink to the parent entity. The migration notes the original Team Engine thread start date and participant phone number for reconciliation. Unlinked contacts (applicants not hired with no Bullhorn Candidate record) are held in a reconciliation queue for the customer to decide whether to create stub Candidate records or exclude message history.
Team Engine
Referrals
Bullhorn ATS & CRM
Custom Object (customObject1)
1:1Team Engine Referral records (referring employee, referred applicant, referral status) require a Bullhorn custom object because Bullhorn does not have a native referral object. We open a Bullhorn Support ticket during migration planning to provision the custom object with fields for referral_source (lookup to Candidate), referring_employee (lookup to Candidate/User), and status. The custom object must be configured by Bullhorn Support before any referral data can be imported via the REST API.
Team Engine
Surveys (Onboarding/Exit)
Bullhorn ATS & CRM
Custom Object (customObject2)
1:1Team Engine automated onboarding and exit survey responses map to a Bullhorn custom object linked to the corresponding Candidate. Survey question text is not migratable as Team Engine stores responses without the full question schema in the data export; we document the survey structure separately so the customer's Bullhorn admin can configure the equivalent fields in the custom object. A Bullhorn Support ticket is required to provision this custom object as well.
Team Engine
Workflow Triggers
Bullhorn ATS & CRM
Not migratable
lossyTeam Engine automated triggered messages (new hire alerts, milestone reminders, survey triggers) are platform configuration, not data records. There is no documented export for automation rules. We cannot migrate workflow logic to Bullhorn. We perform a configuration audit of all active Team Engine triggers and deliver a written inventory listing each trigger's name, condition, action, and a recommended Bullhorn Automation equivalent for the customer's admin to rebuild manually in Bullhorn.
Team Engine
Custom Fields
Bullhorn ATS & CRM
Custom Fields or Custom Objects
lossyTeam Engine custom fields are not well-documented in public API references and require manual discovery during scoping. We extract the full Team Engine field inventory from the CSV export, identify which are standard versus custom, and map custom fields to either Bullhorn custom fields (on standard entities) or Bullhorn custom objects (for structured data). Bullhorn custom fields on standard entities (Candidate, JobOrder, ClientContact) are available from any edition and are configured via Admin > Field Mappings. Bullhorn custom objects require a Bullhorn Support ticket.
Team Engine
Owner
Bullhorn ATS & CRM
User
1:1Team Engine owner assignments (on Jobs, Applicants, Employees) map to Bullhorn User by email match. We resolve each Team Engine owner to a Bullhorn User record during migration. Owners without a matching Bullhorn User are held in a reconciliation queue for the customer's Bullhorn admin to provision before record import resumes.
Team Engine
Company (if applicable)
Bullhorn ATS & CRM
ClientCorporation
1:1If Team Engine has any client or company records beyond the employee context, they map to Bullhorn ClientCorporation. Team Engine's primary use is workforce management rather than client relationship management, so this mapping applies only if the Team Engine instance contains client records. We confirm the existence and volume of company records during scoping.
Team Engine
Placement
Bullhorn ATS & CRM
Placement
1:1If Team Engine tracks placement or hire outcomes (which may exist as an extension of the Applicant record for companies using Team Engine for temp staffing), these map to Bullhorn Placement. The mapping includes the Candidate reference, JobOrder reference, start date, and status. Bullhorn Placement is the canonical record for staffing agency billing and payroll workflows.

Migration approach
Discovery and scoping
We audit the Team Engine instance to extract the full record inventory: Jobs, Applicants, Employees, Employee Groups, message thread count, Referral records, Survey responses, and custom field inventory. We also confirm the Team Engine pricing tier to validate headcount against the Essential 50-employee cap. We open a Bullhorn Support ticket at this stage to request custom object provisioning for Referral and Survey data. The discovery output is a written scope document with record counts per object, a preliminary object mapping, and a decision log for the unlinked contact threads.
Contact reconciliation and unlinked thread decisions
We run the Team Engine contact-phone-to-employee cross-reference to identify all message threads where the Team Engine contact has no corresponding employee record. We deliver this list to the customer and ask for a decision on each batch: create an inactive Bullhorn Candidate stub, exclude the message history, or map to a generic client contact. This decision gates the message migration phase. We do not proceed to message import until the customer signs off on the reconciliation decisions.
Bullhorn custom object setup and schema validation
We coordinate with Bullhorn Support to validate that the custom objects for Referral and Survey data are provisioned with the correct field types and permissions. We also validate the Bullhorn custom field setup on standard entities (Candidate, JobOrder, ClientContact) for any Team Engine custom fields that map to Bullhorn custom fields. Bullhorn schema validation runs in a Sandbox or staging environment before production configuration begins.
Sandbox migration and reconciliation
We run a full migration into a Bullhorn sandbox environment using the customer's production-equivalent data volume. The customer reconciles record counts, spot-checks 25-50 records against the Team Engine source, and validates that tags, custom fields, and date fields transferred correctly. The customer signs off on the sandbox results before production migration begins. Any mapping corrections happen at this stage.
Production migration in dependency order
We run production migration in record-dependency order: JobOrder records first (independent of other entities), then Candidates (with OwnerId resolved from the User mapping), then ClientContacts if applicable, then Tags applied to the migrated entities, then message history (Tasks or Notes via Bullhorn REST API with rate-limit handling), then custom object records (Referrals and Survey responses via REST API after Bullhorn Support confirms custom object setup). Each phase emits a row-count reconciliation report. We disable Bullhorn Automation rules during the migration window to prevent cascading workflow triggers.
Cutover, delta migration, and workflow audit handoff
We freeze Team Engine writes during cutover, run a final delta migration of any records modified during the migration window, then designate Bullhorn as the system of record. We deliver the Team Engine workflow trigger audit document to the customer's Bullhorn admin, with each trigger mapped to a recommended Bullhorn Automation equivalent. We support a one-week hypercare window for reconciliation issues. Workflow rebuild, Bullhorn Automation configuration, and any additional training are outside standard migration scope and can be scoped as a separate engagement.
