Overview

What this migration involves

Migrating from Talent Pool Builder to Bullhorn is a manual-coordination-first project because Talent Pool Builder does not publish a public bulk export API. We begin every engagement by working with the customer's Talent Pool Builder account team to request a full data export, which typically takes three to five business days to produce. Once we receive the export, we validate record counts and completeness before beginning field-level mapping. Talent Pool Builder organizes hiring around Jobs, Candidates, Requisitions, and Talent Pools; Bullhorn uses Job Order, Candidate, Client Corporation, and Opportunity. We map the core object model directly, but custom fields, communication history, and platform-specific compliance flags require configuration-level mapping in Bullhorn. We do not migrate workflows, automations, or job board integrations as code; we deliver a written inventory of these for the customer's admin team to rebuild in Bullhorn's automation framework post-migration.

Why teams make this switch

Two sides of the same decision

Leaving

Talent Pool Builder logo

Talent Pool Builder

What's pushing teams away

  • The user interface feels crowded and clumsy — reviewers note it requires frequent page refreshes and notifications are not always delivered to the right team member.
  • Limited notification routing means recruiters do not always receive alerts when candidates move through stages or when requisitions are created.
  • Account size caps on integrations or exports force growing organizations to migrate to platforms with larger data tolerances.
  • Lack of a publicly documented bulk export API makes data portability difficult without vendor coordination or manual exports.
  • Feature pace creates friction — users report constantly needing to adapt to new changes, which some teams find disruptive to established workflows.

Choosing

Bullhorn ATS & CRM logo

Bullhorn ATS & CRM

What's pulling them in

  • Agencies choose Bullhorn because it combines ATS and CRM in one platform, eliminating the need to switch between separate tools for candidate management and client relationship tracking.
  • The resume parser extracts contact details, work history, and skills into structured, searchable candidate profiles automatically without manual data entry, reportedly driving 24% more placements per recruiter.
  • Bullhorn's placement and split-billing model natively supports contract staffing workflows, handling start/end dates, overtime rules, and multi-party pay/charge rates in a single record.
  • The platform offers extensive third-party integrations through its Recruitment Cloud Marketplace, connecting with back-office, onboarding, and payroll systems used by staffing agencies.
  • 72% of Bullhorn customers are teams with fewer than 10 users, and Bullhorn's implementation team handles setup and data migration for small agencies going live within weeks.

Object mapping

How Talent Pool Builder objects map to Bullhorn ATS & CRM

Each row shows how a Talent Pool Builder 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 Pool Builder

Candidate

maps to

Bullhorn ATS & CRM

Candidate

1:1
Fully supported

Talent Pool Builder candidate records map directly to Bullhorn Candidate entities via the Candidate REST endpoint. We map firstName, lastName, email, phone, and address fields to Bullhorn's Candidate.name, Candidate.email, Candidate.phone, and Candidate.address fields. Application status, source attribution, and stage history map to Bullhorn custom fields or candidate properties. Resume files migrate as Bullhorn CandidateAttachments or ContentDocument records attached to the Candidate. Any Talent Pool Builder custom screening fields map to Bullhorn custom fields (created via Bullhorn's Admin Field Mappings interface before migration). We validate email uniqueness as the dedupe key during insert.

Talent Pool Builder

Job

maps to

Bullhorn ATS & CRM

Job Order

1:1
Fully supported

Talent Pool Builder job postings map to Bullhorn Job Order. The job title, department, location, and posting date migrate to JobOrder.title, JobOrder.department, JobOrder.address, and JobOrder.dateCreated. Talent Pool Builder pipeline stage configuration maps to Bullhorn's JobOrder.status (Available, Pending, Closed) and a Bullhorn custom field pipeline_stage__c preserving the original stage name. Bullhorn's Job Order is the parent entity for submissions and placements, so it must be inserted before any Application or Opportunity records.

Talent Pool Builder

Requisition

maps to

Bullhorn ATS & CRM

Job Order + Custom Object

lossy
Fully supported

Talent Pool Builder requisitions track hiring manager requests and approval workflows before a job is opened. Bullhorn does not have a native requisition object in all editions; we map requisitions to Bullhorn Job Order records with a custom field requisition_status__c set to Pending while the approval workflow is active. If the customer uses Bullhorn's approval workflow features, we configure the requisition as a pre-opening Job Order linked to the hiring manager via a Bullhorn custom lookup field. Requisition approval routing does not migrate as automation; we document the existing routing logic for the customer's Bullhorn admin to configure post-migration.

Talent Pool Builder

Talent Pool

maps to

Bullhorn ATS & CRM

Candidate List + Tags

lossy
Fully supported

Talent Pool Builder talent pools are segmented candidate lists for long-term engagement. Bullhorn does not have a native talent pool object but supports equivalent segmentation through Candidate Tags and Candidate Lists (Bullhorn List entity). We export pool membership and pool-specific tags, then create Bullhorn Tags (applied to Candidate records) and Bullhorn Candidate Lists for pools that require bulk outreach capability. Pool-specific custom fields migrate to Bullhorn custom fields on the Candidate record.

Talent Pool Builder

Application

maps to

Bullhorn ATS & CRM

Candidate + Job Order (submission)

1:many
Fully supported

Talent Pool Builder application records link a Candidate to a Job with a timestamp and stage. Bullhorn models this relationship through a Candidate record linked to a Job Order via the CandidateSubmission (or Submission) entity in Bullhorn ATS/Staffing. We map the application timeline, including stage transitions and recruiter notes, to the Candidate record's custom history fields and to notes attached to the submission. The application timestamp becomes the CandidateSubmission.dateSubmitted.

Talent Pool Builder

Interview Record

maps to

Bullhorn ATS & CRM

Candidate + Note

1:1
Fully supported

Interview scheduling data and scores from Talent Pool Builder map to Bullhorn Candidate records with a Bullhorn custom field interview_score__c and interview_date__c. Free-text interview notes migrate as Bullhorn Note records attached to the Candidate entity via ContentDocumentLink. Bullhorn Interview Scheduling and Bullhorn's built-in interview scorecards can be configured post-migration using the interview data we preserve as a reference. We note any source field that exceeds Bullhorn's 32,768-character Note body limit for manual splitting.

Talent Pool Builder

Offer

maps to

Bullhorn ATS & CRM

Opportunity

1:1
Fully supported

Talent Pool Builder offer records include template placeholders, offer status, and digital signature state. Bullhorn does not have a native offer object but models the offer-to-placement stage through Opportunity with custom fields offer_status__c, offer_amount__c, and offer_template__c. We export the offer data and flag the digital signature status as a Bullhorn custom field signature_status__c for post-migration follow-up. Actual placement records in Bullhorn are modeled as Placement (a staffing-specific entity) that links the Candidate, Job Order, and Client Corporation; we preserve the offer-to-acceptance flow as a state transition documented in the Opportunity custom fields.

Talent Pool Builder

Custom Candidate Properties

maps to

Bullhorn ATS & CRM

Custom Fields + Custom Objects

lossy
Mapping required

Talent Pool Builder accounts frequently create custom fields for screening answers, rating scores, source tracking, and compliance data. These fields vary significantly by account. We request a full Talent Pool Builder field inventory during scoping, then create equivalent Bullhorn custom fields via the Admin Field Mappings interface (Admin > Field Mappings in Bullhorn) or Bullhorn Custom Objects for complex multi-field structures. Bullhorn's Custom Object architecture allows up to 10 searchable custom objects with 55 fields each on Growth/Enterprise tiers, or 2 custom objects on Bullhorn ATS. We configure the schema before migration and map data type mismatches (e.g., Talent Pool Builder free-text to Bullhorn drop-down) to the closest Bullhorn field type, flagging any data that does not fit for manual remediation.

Talent Pool Builder

Communication History

maps to

Bullhorn ATS & CRM

Note

1:1
Mapping required

Talent Pool Builder email, SMS, and call logs attached to candidate records migrate to Bullhorn Note records linked to the Candidate entity. Bullhorn supports Note with a body (up to 32,768 characters) for communication content. Bullhorn's communication tracking features (email sync, SMS integration) can be activated post-migration to capture new communications going forward. We flag communication thread continuity gaps in the scoping report because the chronological thread context may not be preserved in a flat-note export from Talent Pool Builder. Any thread gaps are documented for the customer's hiring managers who rely on conversation history.

Talent Pool Builder

Attachments

maps to

Bullhorn ATS & CRM

ContentDocument + CandidateAttachment

1:1
Mapping required

Resume files and uploaded documents from Talent Pool Builder migrate as Bullhorn CandidateAttachment records (the Bullhorn-native resume attachment) or ContentDocument records via Bullhorn's Salesforce-backed document management. File naming conventions vary by Talent Pool Builder account and are preserved as-is. We document the original file name and upload date on a Bullhorn custom field for reference. Bullhorn's resume parsing activates on import if the Bullhorn Resume Parsing integration is enabled on the destination account.

Talent Pool Builder

Union / Seniority Flags

maps to

Bullhorn ATS & CRM

Custom Fields (post-migration activation)

lossy
Fully supported

Talent Pool Builder's union compliance flags and seniority-based ranking features are platform-specific and do not map to standard Bullhorn objects. We export the raw seniority_date and union_membership fields as Bullhorn custom date and checkbox fields on the Candidate record. Bullhorn does not activate union compliance or seniority ranking logic natively; the customer's IT or legal team configures any required compliance automation in Bullhorn as a post-migration step. We document the original Talent Pool Builder flag values and their meanings to support the compliance configuration.

Talent Pool Builder

Owner

maps to

Bullhorn ATS & CRM

User

1:1
Fully supported

Talent Pool Builder recruiter owners attached to candidate, job, and application records map to Bullhorn User entities. We resolve owners by email match against the Bullhorn destination User table. Any Talent Pool Builder owner without a matching Bullhorn User goes to a reconciliation queue for the customer's Bullhorn admin to provision before record import resumes. Migration cannot proceed past this step because Bullhorn User references are required on Job Order and Candidate records.

Pair-specific challenges

  • Talent Pool Builder has no public bulk export API

    Talent Pool Builder does not publish a public bulk export API in its developer documentation. All migration scoping relies on manual CSV exports generated from within the platform or vendor-assisted data dumps. We coordinate with the customer's Talent Pool Builder account team early in the engagement to request a full data export, which can take three to five business days to produce. We validate export completeness (record counts by object, file size, field headers) before beginning field mapping and flag any objects that appear truncated or that require a second export request. This coordination step adds a minimum of one week to the project timeline before any data work begins and is the primary schedule risk for this migration pair.

  • Per-account custom field proliferation complicates mapping

    Talent Pool Builder accounts frequently create custom fields for screening answers, rating scores, source attribution, and compliance data. These fields are not consistently named or typed across accounts. Bullhorn's custom field architecture requires explicit field creation (via Admin > Field Mappings) before data can be written to custom properties. During migration scoping we request a full Talent Pool Builder field inventory, map each to an equivalent Bullhorn custom field (or Custom Object on Growth/Enterprise tiers), and flag any with data type mismatches. Accounts with more than 55 custom fields on a single entity may require a Custom Object restructure rather than custom field mapping alone.

  • Bullhorn's custom field limits constrain complex source schemas

    Bullhorn editions impose different limits on custom objects and fields. Front Office Growth and Enterprise support up to 10 searchable Custom Objects with 55 fields each. Bullhorn ATS supports 2 Custom Objects. ATS Growth does not support Custom Objects. If the Talent Pool Builder source account has complex custom schemas exceeding these limits, we work with the customer to prioritize field migration (required fields, high-data-volume fields) and defer low-priority custom fields to post-migration manual entry. The Bullhorn Custom Object Setup Sheet (submitted via Bullhorn Support) is required for each new Custom Object and must be completed before migration data preparation begins.

  • Communication thread continuity is not preserved in flat export

    Email, SMS, and call history attached to candidate records in Talent Pool Builder may not export as threaded conversations. Individual communication events export as discrete records, but chronological thread context and in-reply-to relationships are not always present in the export. We export what is available as Bullhorn Note records, flag thread gaps in the data validation report, and recommend that the customer communicate the limitation to hiring managers who rely on inbox history for interview context. New communications captured in Bullhorn after migration will build thread history from the cutover date forward.

Migration approach

Six steps for a successful Talent Pool Builder to Bullhorn ATS & CRM data migration

  1. Export coordination and scoping

    We open a coordination request with the customer's Talent Pool Builder account team requesting a full data export across all objects (Candidates, Jobs, Requisitions, Talent Pools, Applications, Interview Records, Offers, Attachments, and Communication History). While awaiting the export (three to five business days), we request a full Talent Pool Builder field inventory, custom field list, and account configuration document. We pair this with a Bullhorn edition review to confirm the custom object and field limits applicable to the destination account. The scoping output is a written migration scope document listing all objects, record counts, custom field mappings, and any objects that exceed Bullhorn's field limits.

  2. Destination schema setup in Bullhorn

    Before any data migration begins, we set up the Bullhorn destination schema in a staging environment or Sandbox. This includes creating Bullhorn custom fields (via Admin > Field Mappings) for Talent Pool Builder custom properties that map to standard Bullhorn entities, creating Bullhorn Custom Objects (using the Bullhorn Custom Object Setup Sheet submitted to Bullhorn Support) for complex multi-field structures, configuring Bullhorn Tags and Candidate Lists for Talent Pool Builder talent pools, and setting up Job Order record types and status values that map to the source pipeline configuration. Bullhorn schema must be validated before production migration because custom fields cannot be deleted after data is written to them.

  3. Data validation and reconciliation

    We receive the Talent Pool Builder export, validate record counts against the scoping estimates, and check for completeness across all object types. We flag truncated exports, missing fields, and any objects that did not appear in the export. We run a data quality pass: deduplicating candidate records by email, validating date formats, and flagging records with missing required fields (name, email) that require remediation before migration. We produce a data validation report and share it with the customer's project lead before proceeding to transform.

  4. Transform and object mapping

    We apply the object mapping rules: Candidates to Bullhorn Candidate, Jobs to Bullhorn Job Order, Applications to Candidate plus CandidateSubmission, Talent Pools to Tags and Candidate Lists, Offers to Opportunity with custom fields, Communication History to Note, and Attachments to CandidateAttachment or ContentDocument. We transform custom field values to match Bullhorn field types, apply the union/seniority flag mapping to custom date and checkbox fields, and resolve Talent Pool Builder owner references against the Bullhorn User table. Any owner without a Bullhorn User match enters the reconciliation queue for the customer's admin to provision.

  5. Production migration in dependency order

    We run production migration into Bullhorn in record-dependency order: Users (manual provisioning validated), Job Orders (no parent dependencies), Client Corporations (if applicable), Candidates (with email dedupe key), Custom Objects (after parent Candidates exist), Candidate Submissions linking Candidates to Job Orders, Notes for Communication History, Attachments for resumes and documents, and Opportunities for Offer records with custom fields. Each phase emits a row-count reconciliation report before the next phase begins. We use Bullhorn's REST API with exponential backoff on rate-limit responses (standard rate is 10 requests per second for most tiers) and batch inserts for large record sets.

  6. Cutover, validation, and automation handoff

    We freeze Talent Pool Builder writes during cutover, run a final delta migration of any records modified during the migration window, then enable Bullhorn as the system of record. We deliver the automation and workflow inventory document to the customer's Bullhorn admin team, listing any Talent Pool Builder automations, approval workflows, and integration connections that require rebuild in Bullhorn. We do not rebuild Talent Pool Builder automations as Bullhorn workflows inside the migration scope; that is a separate engagement or an internal admin task. We support a one-week post-cutover window for reconciliation issues raised by the customer's recruiting team.

Most migrations land between five and eight weeks for accounts under 5,000 candidates and 500 jobs with no complex custom object schemas. The primary schedule driver is the Talent Pool Builder export coordination, which adds a minimum of one week before any data work begins. Migrations with large talent pool archives (over 10,000 segmented candidate records), significant custom field inventories, or communication histories exceeding 100,000 records move to ten to fourteen weeks because of export validation, Bullhorn Custom Object schema setup through Bullhorn Support, and Bulk API chunking for large record sets.
