Overview

What this migration involves

Migrating from Talos ATS to Bullhorn is an outbound ATS migration with a non-negotiable constraint: Talos ATS does not publish a self-service REST API, so all data extraction requires Talos360 professional services. We coordinate the export package directly with Talos360, validate field completeness before mapping, and handle the resulting lead-time in the project schedule. On the Bullhorn side, the platform uses two distinct data models — ATS v1 (per-stage Custom Objects with a Job Reporting junction object) and ATS v2 (Application V2 with a Stage picklist and Application History) — and the choice between them affects how Talos pipeline stages map. We determine the appropriate model during scoping based on the customer's Bullhorn edition and existing configuration. Candidate records, job postings, applications, interview records, and free-text notes migrate as structured data. Workflow automations, the Tali AI agent tagging logic, and add-on module records (e-Sign contracts, DBS check results, SMS history) do not migrate; we deliver a written inventory for the customer's admin to rebuild in Bullhorn's workflow builder.

Why teams make this switch

Two sides of the same decision

Leaving

Talos ATS logo

Talos ATS

What's pushing teams away

  • The system was described as clunky at launch, with invoice management and initial setup requiring more effort than expected during the first months.
  • A verified reviewer noted the team were slow to enhance the product and reluctant to collaborate on customisations after contract signing.
  • As a UK-centric platform, international organisations report that localisation support outside Europe is less mature than competitors targeting a global market.

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 Talos ATS objects map to Bullhorn ATS & CRM

Each row shows how a Talos ATS 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.

Talos ATS

Candidate

maps to

Bullhorn ATS & CRM

Candidate

1:1
Fully supported

Talos Candidate records map directly to Bullhorn Candidate. The Talos candidate record holds contact details, CV (as document), application history, and stage progression. We map the Talos firstName and lastName to Bullhorn Candidate name fields, email to the Candidate email field, and phone to the phone field. The Talos CV document migrates as a ContentDocumentLink attached to the Candidate record. All candidate custom fields discovered in the audit phase map to Bullhorn custom fields on the Candidate entity, subject to the per-entity custom field limit (2 custom objects with 55 fields each on Bullhorn ATS tier; 10 with 55 fields each on Growth/Enterprise). Talos candidate status flags (active, dormant, blacklisted) map to Bullhorn Candidate isDeleted and status fields with a custom status_reason__c field for blacklist attribution.

Talos ATS

Job (Vacancy)

maps to

Bullhorn ATS & CRM

Job Order

1:1
Fully supported

Talos Job records map to Bullhorn Job Order (JobPosting). The Talos job title, description, location, department, and status migrate as Bullhorn JobOrder.title, description, address, category, and status. Talos postingUrl maps to Bullhorn externalReference. Active and closed jobs migrate; the Bullhorn job status field reflects the Talos status (Open, Placed, Closed). If Talos jobs use custom internal job IDs, these map to a custom field job_customid__c on the Bullhorn Job Order for cross-reference.

Talos ATS

Application

maps to

Bullhorn ATS & CRM

Submission (ATS v1) or Application V2 (ATS v2)

lossy
Fully supported

Talos Application records link a Candidate to a Job and track stage progression. The mapping depends on the destination Bullhorn data model chosen during scoping. Under ATS v1, each Talos application generates multiple per-stage Submission records (one per pipeline stage) plus Job Reporting junction records; we map the Talos stage name to the corresponding Bullhorn Submission stage. Under ATS v2, a single Application V2 record is created per Candidate-Job pair with stage controlled by a picklist, and stage transitions generate Application History records. We determine the appropriate model based on the customer's Bullhorn edition and existing configuration, and document the stage mapping matrix before migration begins. Stage rules and automation triggers tied to Talos stage transitions do not transfer.

Talos ATS

Pipeline Stage

maps to

Bullhorn ATS & CRM

Submission Stage (ATS v1) or Stage Picklist (ATS v2)

lossy
Fully supported

Talos allows fully custom stage names and arbitrary stage counts per job or pipeline. Bullhorn ATS v1 represents each stage as a separate Custom Object, while ATS v2 uses a Stage picklist on the Application V2 record. We extract the customer's Talos stage labels and consolidate or remap them based on the Bullhorn edition: Bullhorn ATS (2 custom objects) may require stage count reduction; Bullhorn Growth/Enterprise (10 custom objects) provides more flexibility. Bullhorn's standard stages (Application, Submittal, Interview, Offer, Placement) are used as the default label set, with Talos custom labels mapped as aliases. Stage probability percentages are set on Bullhorn Stage records during configuration.

Talos ATS

Interview

maps to

Bullhorn ATS & CRM

SendOut + Event

1:1
Fully supported

Talos Interview records (date, interviewer, type, outcome notes) map to Bullhorn SendOut records for the submission-to-interview transition and to Event records for calendar and attendee tracking. The Talos interview type maps to Bullhorn SendOut type (Phone Screen, Video Interview, On-site, Technical). Interview outcome notes migrate as free-text on the SendOut record or as a Note attached to the Candidate. Talos video interview transcription content does not carry to Bullhorn as a native field; we flag this for the customer's admin to assess whether the transcription content should be stored as a Note or discarded.

Talos ATS

Note

maps to

Bullhorn ATS & CRM

Note

1:1
Fully supported

Free-text notes attached to Talos Candidates and Applications migrate as Bullhorn Note records linked via ContentDocumentLink to the parent record (Candidate, Job Order, or Submission). Note timestamps and owner attribution migrate. Notes created by the Tali AI agent that contain auto-generated tagging or commentary are included as-is without transformation; we flag these during the audit phase so the customer is aware that AI-generated notes may not reflect the same context in Bullhorn.

Talos ATS

Assessment

maps to

Bullhorn ATS & CRM

Custom Object (ATS Growth/Enterprise) or Custom Fields (ATS)

lossy
Fully supported

Structured scoring rubrics and Assessment data from Talos require field-level mapping to Bullhorn. On Bullhorn ATS (2 custom objects), Assessment records may require consolidation into a single Custom Object with a section-header layout; on Bullhorn Growth/Enterprise (10 custom objects), each Assessment type can map to its own Custom Object. We discover Assessment field types during the data audit and create the corresponding Bullhorn Custom Object schema before migration. Assessment scores that use a Talos-specific rubric scale are preserved as numeric or text fields with a custom field rubric_scale__c documenting the original scale.

Talos ATS

User (Recruiter / Hiring Manager)

maps to

Bullhorn ATS & CRM

Bullhorn User

1:1
Fully supported

Talos Users assigned as owners on Candidate, Job, and Application records map to Bullhorn User records by email match. We extract all distinct Talos user references during the audit and validate against the Bullhorn destination User table before migration. Inactive or departed Talos users are flagged for reassignment; the customer's Bullhorn admin provisions any missing Users. OwnerId references on Bullhorn records (Candidate, Job Order, Submission) require a resolved User before insert.

Talos ATS

Client Contact (Talos multi-brand)

maps to

Bullhorn ATS & CRM

Client Corporation + Contact

1:many
Fully supported

Talos ATS stores client contacts within its multi-brand pipeline structure. When migrating to Bullhorn, these split into two records: Client Corporation (the employing organisation) and Contact (the individual within that organisation). We extract Talos client name and address data, create Bullhorn ClientCorporation records, then create Bullhorn Contact records linked via the clientCorporationId lookup. Multi-brand Talos deployments may have client records per franchise; we aggregate these into a single Client Corporation hierarchy in Bullhorn if the customer's Bullhorn configuration supports it.

Talos ATS

Offer

maps to

Bullhorn ATS & CRM

Placement

1:1
Fully supported

Talos Offer records (compensation, start date, status) map to Bullhorn Placement. The Talos offer status (pending, accepted, declined, withdrawn) maps to Bullhorn Placement status values. Compensation details migrate to Placement payRate, billRate, and overtimeRate fields. Offer acceptance workflow state from Talos (including any e-Sign Docusign status) is flagged as a separate data pull since e-Sign records are stored in the Docusign integration, not in Talos core. We recommend a separate Docusign export and re-link signed offer documents to Bullhorn Placement records post-migration.

Talos ATS

Custom Field (Job / Candidate)

maps to

Bullhorn ATS & CRM

Custom Field or Custom Object

lossy
Fully supported

Talos custom fields on Jobs and Candidates are discovered during the data audit phase. Bullhorn custom fields on Candidate, JobOrder, and Submission entities are available up to the per-entity limit. If Talos custom fields exceed the Bullhorn field limit, we recommend creating a Custom Object with a lookup to the parent record. Multi-select and checkbox Talos field types map to Bullhorn Multi-Select Picklist and Checkbox field types respectively. Date fields, numeric fields, and free-text fields map directly with type preservation.

Talos ATS

Reports and Dashboards

maps to

Bullhorn ATS & CRM

Reports (rebuild required)

1:1
Not supported

Talos multi-brand franchise reporting dashboards and saved report configurations are platform-specific and do not export cleanly. We do not migrate reporting configurations. We deliver a written inventory of every Talos report and dashboard with its filters, metrics, and visualisation type, plus the raw migrated data in a format compatible with Bullhorn Report Builder. The customer's Bullhorn admin or a reporting consultant rebuilds the reports post-migration using the migrated data.

Pair-specific challenges

  • Talos has no public API — Talos360 export coordination adds lead time

    Talos ATS does not publish a self-service REST API. All data extraction for migration must go through Talos360's professional services team or a facilitated export, which adds a coordination step not present in most ATS migrations. We request the export package from Talos360 at project kickoff and validate field completeness (record counts, custom field presence, document attachments, stage history) before beginning the mapping phase. Any gaps in the Talos360 export appear as missing data in Bullhorn if not flagged and addressed upfront. Talos360's export timeline is quoted separately and typically runs two to four weeks for a full data dump, extending the overall project schedule.

  • Bullhorn ATS v1 and v2 data models produce different stage histories

    Bullhorn runs two distinct ATS data models that affect how stage history is stored. ATS v1 (the legacy model) creates a separate Custom Object record for each pipeline stage a candidate passes through, plus a Job Reporting junction object that tracks stage status (Current, Accepted, Rejected). ATS v2 creates one Application V2 record per Candidate-Job pair with a Stage picklist and Application History records for each transition. Talos stage history may be stored as a linear progression, but the Bullhorn representation differs structurally between v1 and v2. We determine which model applies during scoping based on the customer's Bullhorn edition and existing configuration, and document the mapping accordingly. Switching data models mid-migration is not supported and must be resolved before any data loads.

  • Talos e-Sign, DBS, and SMS add-on records require separate data pulls

    Talos ATS add-on modules — e-Sign (Docusign), DBS Checks (Credence), Reference Checking, and SMS via Twilio — store their records in the respective integrated service rather than in Talos core. The core Talos export does not include these records. We scope add-on usage during the audit phase and flag which records require a separate export from the integrated service. DBS check results contain sensitive personal data that must be handled under GDPR during transit and import into Bullhorn; we coordinate a secure transfer method and confirm Bullhorn's data storage compliance before loading. Docusign-signed offer documents require re-attachment to Bullhorn Placement records post-migration.

  • Talos custom pipeline stages may exceed Bullhorn ATS tier limits

    Talos allows an arbitrary number of custom pipeline stages per job or pipeline, with no documented maximum. Bullhorn ATS tier limits the number of searchable Custom Objects to 2 (Bullhorn ATS), with 55 fields each. Bullhorn Growth/Enterprise raises this to 10 Custom Objects. Talos customers with more than two distinct stage groups (for example, separate stages for permanent, contract, and executive search pipelines) will need to consolidate or map multiple Talos pipelines to fewer Bullhorn Custom Objects. We identify the consolidation requirement during the audit phase and present the customer with stage reduction options before migration mapping begins.

  • Tali AI agent tagging logic does not migrate to Bullhorn AI

    Talos ATS includes the Tali AI hiring agent that applies tagging logic to candidates and job postings — auto-generated scorecard content, candidate ranking tags, and screening commentary. Bullhorn AI & Automation uses a different AI model (Digital Workers for sourcing, screening, and submission) with no direct import of Talos AI-generated data. Tali-generated tags that exist as structured data on Talos Candidate records migrate as custom fields with their original values, but the AI logic that created them is not portable. We flag every Tali AI-generated field during the audit so the customer understands what AI context is lost at cutover.

Migration approach

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

  1. Talos360 export coordination

    We contact Talos360 professional services at project kickoff to initiate the data export. We provide Talos360 with a structured data request covering Candidates, Jobs, Applications, pipeline Stages, Interview records, Notes, custom field definitions, and user directory. We validate the export package on receipt — checking record counts against Talos system reports, confirming custom field presence, verifying document attachment inclusion, and spot-checking stage history completeness. Any gaps are escalated to Talos360 before mapping begins. This step typically runs two to four weeks and is the critical path for the overall project schedule.

  2. Bullhorn edition assessment and data model selection

    We assess the customer's target Bullhorn edition (Starter at $99/user, Core at $165/user, or Pro with AI and automation) based on the Talos data scope and the customer's feature requirements. The ATS v1 versus ATS v2 decision is made here: Bullhorn ATS tier defaults to ATS v1 unless a specific request is made to Bullhorn Support to enable ATS v2. We configure the Bullhorn sandbox with the chosen data model, create the required Custom Objects and custom fields based on the Talos audit, and map the pipeline stage configuration. Bullhorn edition and data model choices are locked before migration mapping begins.

  3. Stage mapping and custom object schema build

    We extract the full Talos pipeline stage label set and map each to a Bullhorn stage. Under ATS v1, we create the required Custom Objects for each stage group (Application, Submittal, Interview, Offer, Placement as defaults with Talos custom labels as aliases). Under ATS v2, we configure the Stage picklist values to match Talos labels. We apply stage probability percentages to match Talos where available, and consolidate or flag any Talos stages that exceed the Bullhorn custom object or picklist limit. The schema is deployed to the Bullhorn sandbox for validation before production migration.

  4. Owner reconciliation and user provisioning

    We extract every distinct Talos user referenced on Candidate, Job, Application, Interview, Note, and Offer records. We match by email against the Bullhorn destination User table. Talos users without a matching Bullhorn User are added to a reconciliation queue with the Talos role and last active date, so the customer's Bullhorn admin can provision the correct Bullhorn User (active for current recruiters, inactive for departed staff) before migration inserts records. OwnerId references on Bullhorn records must be resolved before record insert; this step gates the production migration.

  5. Production migration in dependency order

    We run production migration in record-dependency order: Client Corporations and Contacts first (from Talos client data), then Job Orders, then Candidates, then Applications (as ATS v1 Submissions or ATS v2 Application V2 records), then Interviews as SendOuts and Events, then Notes as ContentDocumentLinks, then Offers as Placements, then custom field data into Custom Objects. Talos360 is notified of the cutover window so no new records are created during migration. We run a delta pass after the initial load to capture any records modified during the migration window.

  6. Cutover and workflow rebuild handoff

    We freeze writes in Talos ATS during cutover, run the final delta migration, then confirm Bullhorn as the system of record. We deliver the workflow inventory document listing every Talos automation trigger, condition, and action for the customer's Bullhorn admin to rebuild in Bullhorn's workflow builder (Bullhorn Automation or Bullhorn Pro workflow configuration). We deliver the report and dashboard inventory for rebuild in Bullhorn Report Builder. We provide a one-week hypercare window for reconciliation issues. We do not rebuild Talos Workflows or Tali AI automations as Bullhorn automations inside the migration scope; that is a separate engagement.

Most migrations land between five and seven weeks for accounts under 10,000 candidate records, 500 jobs, and no multi-brand Talos configuration. The Talos360 export coordination step adds two to four weeks to the front of the project that overlaps with scoping and schema design. Larger migrations with multi-brand pipeline configurations, over 500,000 application-stage history records, or custom objects requiring Bullhorn Custom Object setup (especially on Bullhorn ATS tier with its two-object limit) move to ten to fourteen weeks.
