Overview

What this migration involves

Moving from Teamtailor to Bullhorn is a migration from an employer-brand-first ATS to a staffing-agency ATS with embedded CRM. Teamtailor organizes data around Candidates, Jobs, and Applications with department and location taxonomies; Bullhorn organizes around Candidates, Jobs, Clients (Companies), Placements, and Opportunities with a CRM-native data model. The structural difference matters most for companies using Teamtailor's multi-brand feature or storing client records alongside candidate records — Bullhorn separates these into distinct entities that must be reconciled during scoping. We extract Candidates and Applications with full custom field coverage, map Teamtailor departments and locations to Bullhorn's equivalent taxonomies, and preserve interview kit names as Bullhorn notes for your admin to rebuild structured interview guides. Teamtailor automations and trigger rules are not exposed via the public API and do not migrate; we document every active automation visible in the UI for your team to rebuild in Bullhorn's workflow builder.

Why teams make this switch

Two sides of the same decision

Leaving

Teamtailor logo

Teamtailor

What's pushing teams away

  • Custom field and workflow customization becomes restrictive as hiring volume grows, with reviews noting rigid templates that cannot be bent to team-specific processes.
  • Basic analytics and reporting lack depth — users report that meaningful recruitment reporting requires exporting data to external BI tools.
  • Glitches and login issues surface intermittently, with users citing platform stability problems affecting day-to-day usability.
  • Automation for candidate entry is limited, forcing recruiters to perform manual data entry for incoming applications that should be auto-populated.

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 Teamtailor objects map to Bullhorn ATS & CRM

Each row shows how a Teamtailor 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.

Teamtailor

Candidate

maps to

Bullhorn ATS & CRM

Candidate

1:1
Fully supported

Teamtailor Candidates map directly to Bullhorn Candidate records. The HubSpot-equivalent model in Bullhorn, Candidate stores name, email, phone, address, employment history, and education. Teamtailor custom fields on candidates migrate to Bullhorn custom fields on the Candidate entity, which we pre-create during schema design. We resolve the Teamtailor user (recruiter owner) by email match against Bullhorn User and assign OwnerId on insert.

Teamtailor

Job

maps to

Bullhorn ATS & CRM

Job

1:1
Fully supported

Teamtailor Jobs map to Bullhorn Jobs. The job title, status (active/paused/closed), department, location, and body content transfer directly. Bullhorn Job status values map from Teamtailor's published, paused, and archived statuses. Job custom fields migrate to Bullhorn Job custom fields. We preserve the public job URL from Teamtailor as a reference field for back-links to the original posting.

Teamtailor

Job Application

maps to

Bullhorn ATS & CRM

Candidate Job Submission

1:1
Fully supported

Teamtailor Job Applications link a Candidate to a Job with a status, source, and timestamps. These map to Bullhorn Candidate Job Submissions, which are the primary join records between Candidate and Job in Bullhorn's ATS model. Application status, rejection reasons, and submission date transfer. We write Applications after both the Candidate and Job exist in Bullhorn to satisfy foreign key constraints.

Teamtailor

Department

maps to

Bullhorn ATS & CRM

Department

1:1
Fully supported

Teamtailor Departments export as a flat list from the /v1/departments endpoint and map to Bullhorn Department records. Bullhorn uses Department as an organizational taxonomy on Job records. We import departments before Jobs so that the DepartmentId lookup is satisfied at Job insert time.

Teamtailor

Location

maps to

Bullhorn ATS & CRM

Office

1:1
Fully supported

Teamtailor Locations map to Bullhorn Office records. Bullhorn Office stores geographic data (city, state/region, country) and can be linked to Job and Candidate records. We import Offices before Jobs to satisfy location lookups. If Teamtailor locations contain complex address components, we parse them into Bullhorn's address subfields during the transform step.

Teamtailor

Custom Field (Candidate)

maps to

Bullhorn ATS & CRM

Custom Field (Candidate)

1:1
Fully supported

Teamtailor candidate custom fields are discovered by sampling candidate records during a discovery pass since Teamtailor does not expose a metadata endpoint. We inspect returned attributes across 25-50 sample records to build the full field list with types inferred from values. Each discovered field is pre-created in Bullhorn with a matching type (text, number, date, picklist) before the Candidate migration phase begins. Fields that exceed Bullhorn's per-entity custom field limit are flagged for Custom Object conversion.

Teamtailor

Custom Field (Job)

maps to

Bullhorn ATS & CRM

Custom Field (Job)

1:1
Fully supported

Teamtailor job custom fields are scoped to the Job object and discovered alongside candidate custom fields during the same discovery pass. These map to Bullhorn custom fields on the Job entity. Job custom fields are typically fewer than candidate custom fields because Teamtailor's job templates have a more constrained schema. We create Bullhorn fields during schema design before the Job import phase.

Teamtailor

User (Hiring Team)

maps to

Bullhorn ATS & CRM

User

1:1
Fully supported

Teamtailor Users (recruiters and hiring managers) map to Bullhorn User records by email match. We export the full user list from /v1/users and reconcile against Bullhorn's User table. Any Teamtailor user without a matching Bullhorn User goes to a reconciliation queue for the customer's Bullhorn admin to provision before the Candidate migration phase runs.

Teamtailor

Interview Kit and Question

maps to

Bullhorn ATS & CRM

Custom Object or Note

1:1
Fully supported

Teamtailor Interview Kits group structured questions tied to jobs. Bullhorn does not have a native Interview Kit equivalent. We export kit names, question text, and question type from Teamtailor's API and write them as Bullhorn Note records linked to the corresponding Job, with the kit name in the Note title for discoverability. The customer's Bullhorn admin uses these as source material to rebuild structured interview guides in Bullhorn.

Teamtailor

Upload and Attachment (Resume, Cover Letter)

maps to

Bullhorn ATS & CRM

Candidate Attachment

1:1
Fully supported

Teamtailor stores resumes, cover letters, and other files as upload objects with API URLs. We fetch each file from the provided URL and upload it as a Candidate Attachment in Bullhorn using the Bullhorn REST API's attachment endpoints. File type, filename, and upload date are preserved. Attachments are written after the parent Candidate record exists to satisfy the foreign key.

Teamtailor

Candidate Answer (Application)

maps to

Bullhorn ATS & CRM

Candidate Custom Field Value

1:1
Fully supported

Teamtailor stores candidate answers to job application questions as separate answer objects linked to the application. We extract answers per application by querying /v1/answers with date-bounded pagination to avoid HTTP 500 errors on large datasets. Answers map to Bullhorn custom field values on the Candidate Job Submission record, using the question text as the field label.

Teamtailor

Action and Activity Log

maps to

Bullhorn ATS & CRM

Task

1:1
Fully supported

Teamtailor Actions (stage changes, status updates, notes logged by recruiters) are exported from /v1/actions with date-bounded pagination. Bullhorn does not have a direct activity log equivalent, so we write Action records as Bullhorn Task entries with a custom field action_type__c carrying the original action type, preserving timestamps for audit. This is not a 1:1 migration of the activity timeline but a structured record of significant candidate interactions.

Teamtailor

Multi-Brand Configuration

maps to

Bullhorn ATS & CRM

Scoped Entity Export

lossy
Fully supported

Teamtailor's Multi-Brand feature allows separate employer brands with separate career sites and candidate pools under one account. Bullhorn does not have a native multi-brand equivalent; brands are typically modeled as separate Bullhorn accounts or as a Job Classification taxonomy within a single account. We scope the export to a single Teamtailor entity during migration and document the multi-brand structure for the customer to decide whether to run separate Bullhorn accounts per brand or consolidate under one org.

Teamtailor

Candidate Stage (Application Status)

maps to

Bullhorn ATS & CRM

Candidate Job Submission Status

lossy
Fully supported

Teamtailor application statuses (applied, screening, interview, offer, rejected, hired) map to Bullhorn Candidate Job Submission status values. We create a Bullhorn Status Category or use the existing status workflow to match Teamtailor's pipeline stages. Closed statuses (rejected, hired) map to Bullhorn's isClosed flag.

Pair-specific challenges

  • Teamtailor answers and actions endpoints require date-bounded pagination

    Teamtailor's /v1/answers and /v1/actions endpoints return HTTP 500 when requested without filters on accounts with large application histories. Teamtailor's own API guidance instructs clients to use date-bounded queries to avoid this. We split these endpoints into month-bounded slices during export, iterating by application date range to keep payload sizes manageable. Migrations that ignore this return empty result sets or 500 errors, silently dropping candidate answer data and activity history.

  • Teamtailor API rate limit of 50 requests per 10 seconds requires request pacing

    Teamtailor's API enforces a rolling bucket of 50 requests every 10 seconds. For customers with thousands of candidates, jobs, and applications, naive bulk extraction triggers HTTP 429 responses and stalls the migration. We pace our extraction workers to stay within the 50-request window, queue retries with exponential backoff on throttled responses, and use cursor-based pagination to minimize request count per object type.

  • Custom fields have no unified schema endpoint in Teamtailor

    Teamtailor does not expose a metadata API enumerating all active custom fields for an account. Field names and types must be discovered by querying actual records and inspecting returned attributes. We run a discovery pass on 25-50 sample records per entity before running the full export, building the field map incrementally. Custom fields not discovered during scoping are silently dropped on a naive export, which is a data integrity risk for customers with extensive custom schemas.

  • Bullhorn custom field slots are limited per entity and Custom Component Fields are restricted

    Bullhorn's Knowledge Base explicitly states that Custom Component Fields are reserved for integrations and are not supported for general client configuration. Standard custom fields on Bullhorn entities (Candidate, Job, Company) have a finite per-entity limit. If Teamtailor's custom field schema exceeds Bullhorn's per-entity allocation, we convert overflow fields to Bullhorn Custom Objects with lookup relationships to the parent record. This requires schema pre-creation during the design phase, not during migration.

  • Teamtailor automations do not migrate and are not exposed via API

    Automation workflows and trigger rules configured in Teamtailor (e.g., send email when candidate moves to a specific stage) exist only in the UI and are not exposed via the public API in a structured way. We do not migrate them. During scoping we document every active automation visible in the Teamtailor UI as a checklist, with the trigger, conditions, and actions described in plain language. The customer's Bullhorn admin rebuilds these in Bullhorn's workflow builder post-migration. This is a manual rebuild effort that is excluded from standard migration scope.

Migration approach

Six steps for a successful Teamtailor to Bullhorn ATS & CRM data migration

  1. Discovery and API scoping

    We authenticate against Teamtailor's JSON API with the required X-Api-Version header and run discovery across all entity types: Candidates, Jobs, Job Applications, Departments, Locations, Users, and custom field schemas. We sample 25-50 records per entity to discover all active custom field names and types since Teamtailor has no metadata endpoint. We count total records per entity, estimate API extraction time given the 50 req/10s rate limit, and identify any multi-brand sub-entities requiring separate scoping. The output is a written migration scope document with record counts, custom field inventory, and a Teamtailor-side data health assessment.

  2. Destination schema design in Bullhorn

    We design the Bullhorn destination schema based on the Teamtailor discovery output. This includes pre-creating Bullhorn custom fields on Candidate, Job, and Candidate Job Submission entities to match the discovered Teamtailor custom field inventory. If the Teamtailor schema exceeds Bullhorn's per-entity custom field limit, we convert overflow fields to Bullhorn Custom Objects. We configure department and office taxonomies, map Teamtailor application statuses to Bullhorn Candidate Job Submission statuses, and set up the interview kit documentation structure (Bullhorn Notes). Bullhorn schema changes deploy into the customer's Sandbox or staging org first for validation.

  3. Sandbox migration and reconciliation

    We run a full extraction and load into a Bullhorn Sandbox using production-like data volumes. The customer's recruiting operations lead reviews record counts in Bullhorn (Candidates in, Jobs in, Applications in), spot-checks 25-50 randomly selected candidate records against Teamtailor source data, and validates custom field values. Any mapping corrections, missing fields, or data quality issues are resolved in the sandbox phase. This step prevents discovery of data issues after production cutover.

  4. File attachment extraction

    We extract candidate resume and cover letter files from Teamtailor's upload URLs. Each file is fetched with the Teamtailor API token and uploaded to Bullhorn as a Candidate Attachment via Bullhorn's attachment REST endpoints. File types, filenames, and dates are preserved. Attachments are written after the parent Candidate record exists to satisfy foreign key constraints.

  5. Production migration in dependency order

    We run the production migration in record-dependency order: Departments and Offices (taxonomies first), then Users (owner reconciliation validated), then Jobs (with DepartmentId and LocationId resolved), then Candidates (with OwnerId resolved and custom fields populated), then Candidate Job Submissions (with CandidateId and JobOrderId resolved and application status mapped), then candidate answers (linked to submission via question text mapping), then interview kit documentation (Bullhorn Notes linked to Job), then actions (Bullhorn Tasks with action_type__c custom field). Each phase emits a row-count reconciliation report before the next phase begins.

  6. Cutover, validation, and automation rebuild handoff

    We freeze writes in Teamtailor 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 inventory document listing every Teamtailor automation with trigger, conditions, and actions for the customer's Bullhorn admin to rebuild. We support a one-week hypercare window for reconciliation issues. Post-migration admin support, Bullhorn workflow rebuilding, and training are outside standard migration scope and are separate engagements.

Most migrations land between three and five weeks for accounts with fewer than 15,000 candidates, 500 jobs, and no multi-brand configuration. Multi-brand setups, large application histories (over 100,000 application records), or extensive custom field schemas (over 50 fields) extend the timeline to seven to twelve weeks because of per-entity scope analysis, file attachment extraction, and custom object conversion work. Bullhorn's own guidance for staffing agencies cites two weeks for small agencies and two to six weeks for mid-size agencies; our migrations typically run in parallel with Bullhorn's onboarding process.
