Overview
Moving from Talent Clue to Bullhorn is a platform upgrade from an SME-focused ATS to an enterprise recruitment CRM and ATS. Talent Clue structures recruitment around vacancies and candidates; Bullhorn adds ClientCorporation, ClientContact, Opportunity, and Placement as first-class entities in a full client-to-placement cycle. The critical technical constraint on the source side is that Talent Clue does not publish a public REST API, so all data extraction relies on dashboard CSV or Excel exports, which we chunk by job or date range and merge into complete datasets. We map Talent Clue's talent pool to Bullhorn Candidates with a custom pool flag, translate evaluation scorecards to Bullhorn custom fields or onboarding form responses, and handle Bullhorn's API rate limits with exponential backoff and batch chunking. Workflows, sequences, employer branding assets, and hiring analytics do not migrate; we deliver a written inventory for the customer's admin to rebuild post-migration.

Object mapping
Each row shows how a Talent Clue 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.
Talent Clue
Job
Bullhorn ATS & CRM
JobOrder
1:1Talent Clue Job postings map directly to Bullhorn JobOrder records. We extract title, description, department, location, employment type, and publishing status from the dashboard export. Bullhorn JobOrder supports additional fields (businessSector, salary, benefits, feeArrangement) that Talent Clue does not have; we leave those blank or flag them for manual completion. Active and archived vacancies migrate with their status preserved; draft vacancies migrate as Draft status in Bullhorn unless the customer requests otherwise.
Talent Clue
Candidate
Bullhorn ATS & CRM
Candidate
1:1Talent Clue Candidate records map to Bullhorn Candidate. Contact details, source channel, current stage, and scorecard data transfer directly. Custom candidate properties require field-level mapping; we request the full custom field list during discovery and either match to equivalent Bullhorn standard fields or create custom fields in the destination org. We use email address as the primary dedupe key for candidates appearing in multiple applications.
Talent Clue
Application
Bullhorn ATS & CRM
JobSubmission
1:1Talent Clue Applications (candidate-to-job associations with submission date and pipeline stage) map to Bullhorn JobSubmission. The association links the Candidate and JobOrder entities. Stage history from Talent Clue migrates as a log entry or custom field in Bullhorn because JobSubmission does not natively store a full stage-change audit log. We flag stage transition timestamps for the customer to review during validation.
Talent Clue
Talent Pool
Bullhorn ATS & CRM
Candidate (flagged)
1:1Talent Clue's persistent talent pool is a candidate database independent of vacancies. We export all pool records and create Bullhorn Candidate entries with a custom boolean field pool_candidate__c set to true. The customer can then use Bullhorn's list and search functionality to replicate pool-based outreach. If the destination Bullhorn org has Talent Platform, we may map pool records to a Talent Platform candidate community or list depending on the customer's licensing tier.
Talent Clue
User (Recruiter)
Bullhorn ATS & CRM
User
1:1Talent Clue recruiter accounts own vacancies and candidates. We map Talent Clue users to Bullhorn Users by email address. Bullhorn role and permission structures (Front Office, Back Office, Standard) do not have direct Talent Clue equivalents, so we set the Bullhorn role to Standard by default and flag for the customer's Bullhorn admin to configure permissions post-migration. Inactive Talent Clue users map to inactive Bullhorn users unless explicitly requested.
Talent Clue
Pipeline Stage
Bullhorn ATS & CRM
Opportunity Stage or Placement Status
lossyTalent Clue defines configurable pipeline stages per job or globally. We extract the full stage label and sequence list during discovery and translate them to Bullhorn Opportunity stages (for recruitment pipeline tracking) or Placement statuses (for placed candidate tracking). Bullhorn supports custom stage values per Sales Process or Record Type. We note that custom stage names with industry jargon may not map cleanly and require a label-mapping table agreed upon during scoping.
Talent Clue
Evaluation / Scorecard
Bullhorn ATS & CRM
Custom Fields or Onboarding Forms
lossyTalent Clue evaluation forms capture interviewer ratings and free-text feedback against candidates. Structured scorecard fields map to Bullhorn custom fields on the Candidate entity (up to 55 fields per custom object depending on Bullhorn edition). Free-text feedback migrates as Note records linked to the Candidate. If the destination Bullhorn org includes Talent Platform, evaluation responses may map to onboarding form fields for newly placed candidates.
Talent Clue
Interview
Bullhorn ATS & CRM
Event or Task
1:1Talent Clue interview records include scheduled time, interviewer, duration, and outcome. We export scheduling data and outcome flags. Bullhorn Event records store start time, end time, location, and attendees; outcome flags map to custom fields on Event. If the destination tracks interviews as Tasks rather than Events, we use Task with TaskSubtype = Meeting. Interview records without an outcome map as scheduled Events awaiting completion update.
Talent Clue
Note
Bullhorn ATS & CRM
Note
1:1Talent Clue candidate-level notes migrate as Bullhorn Note records linked via ContentDocumentLink to the parent Candidate. Note body transfers as plain text or rich text depending on the export format. We preserve the original creation date and author where available in the export. Bullhorn Note has a 131,072 character body limit; notes exceeding this truncate with a flag in the validation report.
Talent Clue
Attachment
Bullhorn ATS & CRM
ContentDocument
1:1Talent Clue file attachments on candidates and applications download as files and re-upload to Bullhorn as ContentDocument records with ContentDocumentLink to the parent Candidate or JobSubmission. Large attachment volumes (over 1,000 files) require chunked download and upload batches with checksum validation to ensure completeness. The customer's Bullhorn storage allocation should be reviewed before migration begins.
Talent Clue
Custom Field
Bullhorn ATS & CRM
Custom Field or Custom Object
lossyTalent Clue custom fields on Candidate and Application objects require a field-by-field mapping exercise during discovery. We request a complete list of active custom fields, their data types, and picklist values from the customer. Bullhorn standard fields cover most common cases (text, number, date, picklist, checkbox). For complex custom fields beyond standard type coverage, we create Bullhorn custom fields (field limit varies by edition: ATS Growth none, ATS 2, Front Office Growth/Enterprise 10 custom objects with 55 fields each). We use Bullhorn's REST API /meta endpoint to discover existing custom object schemas before creating new ones.
Talent Clue
Employer Branding Asset
Bullhorn ATS & CRM
File Export
lossyTalent Clue career page branding assets and job ad templates export as downloadable files. Bullhorn does not have a native employer branding asset library comparable to Talent Clue's career site builder. We deliver the assets as a structured file export (logos, banner images, template documents) with a filename convention that identifies their original use. The customer's Bullhorn admin uses these files to rebuild career site branding or uploads them to a connected CMS.
Talent Clue
Hiring Analytics / Reports
Bullhorn ATS & CRM
Not migrated
lossyTalent Clue recruitment reports and funnel analytics are computed within the platform and are not independently exportable as structured data. We flag this limitation upfront and recommend that the customer exports any required reports as static screenshots or PDFs before migration begins. Bullhorn Analytics provides a rebuilt reporting environment post-migration; we do not replicate Talent Clue's specific report definitions.

Migration approach
Discovery and export method confirmation
We audit the source Talent Clue instance for record volumes (candidates, applications, jobs, pool records, evaluations), active custom fields, pipeline stage definitions, user count, and any active Factorial integration. We confirm whether the customer has database-level access to Talent Clue or will rely on dashboard CSV/Excel exports. We review the Bullhorn destination org for existing data, custom objects, user provisioning, and Bullhorn edition (ATS Growth, ATS, Front Office Growth, Enterprise) to confirm custom object limits. The discovery output is a written migration scope document including record counts, export method, custom field mapping table, and stage label translation table.
GDPR audit and deletion pause
We run a candidate completeness audit against the Talent Clue database. Any candidate records that have been deleted via GDPR erasure are flagged as excluded from the migration scope and documented in the final migration report. We request that the customer pauses any automated GDPR deletion workflows or scheduled purges before we begin extraction. If the customer is also using Factorial HR, we cross-reference the Talent Clue hired candidate list against any pre-existing Factorial employee records to identify overlaps. The customer reviews and signs off the exclusion list before extraction begins.
Dashboard export sequencing and data merge
Because Talent Clue has no public API, we coordinate the manual export process. We sequence exports in dependency order: Jobs first (to establish the vacancy list), then Candidates (with pool membership flag), then Applications (with candidate-to-job links), then Evaluations and Interview records, then Notes and Attachments. Large datasets are chunked by date range or job cluster and merged in a staging environment with deduplication by email address. We validate row counts at each export step against the discovery audit figures and flag discrepancies before proceeding to the Bullhorn import phase.
Bullhorn schema preparation and custom object request
We review the Bullhorn destination org's existing schema including standard fields on JobOrder, Candidate, JobSubmission, Opportunity, and Placement. If the migration scope requires custom fields beyond Bullhorn's standard coverage, we submit a Bullhorn Support ticket to create the required custom objects using the Custom Object Setup Spreadsheet. We configure custom fields on Candidate, JobOrder, and JobSubmission to match the Talent Clue custom field definitions agreed during discovery. We configure Opportunity record types and stage values to map from the Talent Clue pipeline stages.
Sandbox migration and reconciliation
We run a full migration into the Bullhorn Sandbox (Partial Copy or Full Copy depending on data volume) using the merged export dataset. The customer's Bullhorn admin reviews record counts, spot-checks 25-50 randomly sampled records against the Talent Clue source, and validates that custom field values, stage labels, and application associations are correct. We correct any mapping errors in the staging environment based on feedback and repeat the sandbox migration until reconciliation passes. Sign-off from the customer's admin on the sandbox migration is required before production migration begins.
Production migration in dependency order and cutover
We run the production migration in record-dependency order: JobOrders (establishing vacancy structure), Candidates (with pool flag), JobSubmissions (with candidate-to-job and stage links), Evaluations and Interview records (via Bulk API), Notes (via ContentDocument), and Attachments (chunked upload with checksum validation). Bullhorn's REST API rate limits are handled with exponential backoff and batch chunking. We freeze Talent Clue writes during the cutover window, run a final delta migration of any records modified during migration, then enable Bullhorn as the system of record. We deliver the custom field mapping summary, stage translation table, employer branding file package, and GDPR exclusion log to the customer's Bullhorn admin.
Post-migration validation and workflow rebuild handoff
We support a one-week hypercare window after cutover where we resolve any record-reconciliation issues identified by the recruiting team. We do not migrate Talent Clue Workflows, Sequences, employer branding site configurations, or hiring analytics reports as code. We deliver a written inventory of active Talent Clue automations, pipeline configurations, and report definitions with Bullhorn equivalents recommended for the customer's admin or a Bullhorn-certified partner to rebuild. Bullhorn Talent Platform onboarding forms require separate configuration beyond migration scope if the customer intends to use them for evaluation or pre-boarding.
