Overview

What this migration involves

Moving from Hireology to Bullhorn is a migration between platforms with fundamentally different core models. Hireology is built around multi-location operational hiring: Jobs live at a specific Location, Candidates apply through Applications, and interview scorecard rubrics vary by location or job type. Bullhorn is built around agency staffing workflows: JobOrders carry a client relationship, Candidates submit through JobSubmissions, and placements track a candidate-to-client engagement after placement. We resolve the schema gap by treating Hireology Jobs as Bullhorn JobOrders, Applications as JobSubmissions, and by surfacing the interview rubric variance that must be normalized before Bullhorn's uniform scorecard model can accept the data. Custom field discovery on the Hireology side requires targeted record sampling because there is no public custom field registry. Bullhorn custom objects must be configured by Bullhorn Support via a setup spreadsheet, with edition-specific limits (none on ATS Growth, two on Bullhorn ATS, ten on Enterprise). We do not migrate Workflow Templates, Job Board distribution history, or background check report documents. We deliver a written inventory of each for your admin to rebuild or re-initiate post-migration.

Why teams make this switch

Two sides of the same decision

Leaving

Hireology

What's pushing teams away

  • The offer letter tool is widely described as unintuitive and cumbersome to configure, forcing some teams to generate letters outside the platform and re-enter data
  • Some customers report missing integrations with payroll providers other than ADP Workforce Now, creating friction for businesses standardized on Netchex or similar platforms
  • Analytics and reporting capabilities are considered shallow by power users, particularly those who want to track pipeline velocity or source attribution across locations
  • The platform is designed around multi-location operational structures, so single-location businesses can find the interface overhead larger than their actual needs
  • Switching costs arise when a multi-location organization has deeply customized workflows tied to Hireology's specific stages and scorecard templates

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 Hireology objects map to Bullhorn ATS & CRM

Each row shows how a Hireology 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.

Hireology

Job

maps to

Bullhorn ATS & CRM

JobOrder

1:1
Fully supported

Hireology Jobs map to Bullhorn JobOrder. The Job's title, description, employmentType, and location address transfer directly. Hireology's Location association (which ties the job to a specific franchise or retail site) maps to JobOrder's address and a custom field jobLocation__c carrying the Hireology Location name. If the destination organization represents multiple former Hireology customers or franchises as separate ClientCorporations, we reassociate each JobOrder to the appropriate Bullhorn client account during import.

Hireology

Candidate

maps to

Bullhorn ATS & CRM

Candidate

1:1
Fully supported

Hireology Candidate records map to Bullhorn Candidate. Core profile fields (firstName, lastName, email, phone, address) migrate directly. We preserve the candidate's Hireology ID in a custom field hireology_candidate_id__c for audit and cross-reference. If a Candidate has applied to multiple Jobs in Hireology, all associated JobSubmissions are preserved against the same Bullhorn Candidate record.

Hireology

Application

maps to

Bullhorn ATS & CRM

JobSubmission

1:1
Fully supported

Hireology Applications map to Bullhorn JobSubmission. Each Application links one Candidate to one Job at one Location. We preserve the applicationDate, current status, and stage-change history where available via Hireology's API. The JobSubmission.dateAdded maps to the Hireology application date. Stage change history is preserved as a custom text area field migration_stage_history__c in JSON format for admin reference.

Hireology

Interview Score

maps to

Bullhorn ATS & CRM

Note or Custom Scorecard

lossy
Fully supported

Hireology interview scorecards are sub-objects on the Application with per-question ratings, rating scales, and free-text reviewer comments. Bullhorn does not have a native standardized interview scorecard object; scorecard data migrates as Note records linked to the JobSubmission, or as a Bullhorn custom object if the customer has commissioned one via Bullhorn Support. Before migration, we surface the rubric variance across locations and job types during the scoping call and ask the customer to confirm the target scorecard format. A uniform rubric is created in Bullhorn before scorecard import begins.

Hireology

Background Check

maps to

Bullhorn ATS & CRM

Candidate (structured fields)

1:1
Fully supported

Background check metadata (check type, result date, pass/fail status) migrates as fields on the Bullhorn Candidate record or in a Bullhorn custom object. The actual screening report documents are not downloadable via Hireology's API and do not transfer. Candidates who have completed background checks in Hireology require re-initiation in Bullhorn, which can delay onboarding for regulated roles. We flag each affected candidate record and provide a re-screening checklist as part of the cutover documentation.

Hireology

Location

maps to

Bullhorn ATS & CRM

ClientCorporation or Address + Custom Field

lossy
Fully supported

Hireology Locations represent individual franchise or retail sites, each with its own hiring manager and configuration. Bullhorn does not have a native multi-location model; franchise or site-level records map to Bullhorn ClientCorporation entities if the organization operates as a client relationship, or to a custom location__c field on JobOrder if the locations are operational divisions rather than clients. The customer's intended Bullhorn data model determines the mapping at scoping.

Hireology

User / Hiring Manager

maps to

Bullhorn ATS & CRM

User

1:1
Fully supported

Hireology users (admins, hiring managers, recruiters) map to Bullhorn Users. We match by email address. Role and permission assignments are documented from Hireology and mapped to Bullhorn Role and Permission Set assignments during the Bullhorn configuration phase. Multi-location role hierarchies in Hireology may require a simplified permission model in Bullhorn if the Bullhorn edition limits role complexity.

Hireology

Custom Field (Job)

maps to

Bullhorn ATS & CRM

JobOrder Custom Field

1:1
Fully supported

Hireology custom fields on Jobs have no public registry. We discover them by sampling a representative set of Job records during the discovery phase, comparing the payload against the standard Hireology Job schema, and building a delta list of non-standard fields. Each discovered custom field maps to a Bullhorn JobOrder custom field, which must be pre-created via Bullhorn Support if the customer is on Bullhorn ATS (two limit) or Bullhorn ATS Growth (none). Enterprise customers with ten available custom object slots have more flexibility.

Hireology

Custom Field (Candidate)

maps to

Bullhorn ATS & CRM

Candidate Custom Field

1:1
Fully supported

Same discovery approach as Job custom fields: we sample Candidate records, identify non-standard fields, and map them to Bullhorn Candidate custom fields. Bullhorn's custom fields per entity are limited by edition, so we prioritize the most operationally critical custom fields and document any that exceed the edition limit for customer review.

Hireology

Custom Field (Application)

maps to

Bullhorn ATS & CRM

JobSubmission Custom Field

1:1
Fully supported

Hireology custom fields on Applications follow the same discovery-and-mapping process. These map to Bullhorn JobSubmission custom fields or a Bullhorn custom object attached to JobSubmission. The edition-specific limit applies across all entity types, so we coordinate custom field allocation across JobOrder, Candidate, and JobSubmission during schema design.

Hireology

SkillSurvey Reference Check

maps to

Bullhorn ATS & CRM

Note or Custom Object on Candidate

1:1
Fully supported

SkillSurvey reference check results embedded in the Hireology Candidate record migrate as structured fields (check date, status, reference type, overall rating) on the Bullhorn Candidate or in a Bullhorn custom object. SkillSurvey does not transfer as an active integration; the reference check history is preserved as data, and future reference checks must be initiated through Bullhorn's integration with a reference check provider or manually.

Hireology

Job Board Distribution

maps to

Bullhorn ATS & CRM

Not migrated

1:1
Fully supported

Job board distribution records (which boards received a posting, when it was distributed, performance metrics) are not exportable via Hireology's public API. We migrate the job content itself. The job posting distribution history must be reconstructed in Bullhorn's job board distribution module post-migration. We provide a list of all historical job posting targets and dates from Hireology's internal records if available, for the customer's admin to re-enter.

Hireology

Workflow Template

maps to

Bullhorn ATS & CRM

Not migrated

1:1
Fully supported

Hireology workflow templates defining stage sequences, automated actions, and approval gates are stored in Hireology's configuration layer and are not accessible via the public API. We deliver a written inventory of every workflow template inferred from the customer's stage configurations, job configurations, and any documented process guides. The customer's Bullhorn admin or implementation partner rebuilds the workflow as Bullhorn placement workflow, Opportunity sales process, or Bullhorn Automation Engine configuration post-migration.

Hireology

ADP Workforce Now Payroll Integration Data

maps to

Bullhorn ATS & CRM

Payroll Provider Setup

1:1
Fully supported

Hireology's ADP Workforce Now integration passes new hire data from the offer stage into payroll. This integration is a connection configuration, not a data record. We document the ADP integration settings and new hire field mapping from Hireology so that the customer's Bullhorn admin can establish a comparable integration with ADP or a different payroll provider in Bullhorn. Active payroll integration data (benefits, deductions, tax withholding) lives in ADP, not in Hireology, and does not require migration from Hireology's ATS layer.

Pair-specific challenges

  • Hireology custom field schema requires active discovery

    Hireology's public API does not expose a custom field registry enumerating all custom fields and their object associations. We must discover the full custom field landscape by sampling records during the discovery phase. If a customer has added custom fields without documenting them, those fields may not appear in our initial mapping and could be silently dropped during migration. We mitigate this by running a targeted record scan across Jobs, Candidates, and Applications and comparing the payload against the standard schema before any data is moved. We also ask the customer directly about any custom fields they know exist.

  • Bullhorn custom objects require Support-ticket provisioning

    Bullhorn custom objects cannot be created via the REST API alone; they must be requested through Bullhorn Support using a setup spreadsheet. Bullhorn edition limits apply: Bullhorn ATS Growth has zero custom object slots, Bullhorn ATS has two, and Bullhorn CRM and Enterprise have up to ten. If Hireology has more than the edition-allowed number of custom fields or custom field groups, we must prioritize the most operationally critical ones and document the remainder for post-migration configuration. Enterprise customers should commission all required custom objects before migration begins to avoid blocking the data import.

  • Interview scorecard rubrics vary by location and job type

    Hireology allows each location or each job type to use a different interview scorecard template with a different number of questions, rating scales, and reviewer assignments. Bullhorn's scorecard model is more uniform. When migrating interview scores to Bullhorn, we must normalize to a common rubric, which may lose the nuance of the original location-specific ratings or questions that do not map to the target Bullhorn scorecard. We surface this variance during the scoping call, ask the customer to confirm the target rubric, and preserve the original per-reviewer ratings in a custom note or field for reference.

  • Background check documents cannot be transferred

    Background check results in Hireology are stored as references or embedded data linked to the screening provider, not as downloadable documents via the Hireology API. We migrate the structured result metadata (check type, date, pass/fail, reference ratings from SkillSurvey) but not the actual report documents. Candidates who have completed background checks may need to re-initiate screening in Bullhorn, which can delay onboarding for roles requiring verified credentials. We flag each affected candidate and provide a re-screening checklist as part of cutover documentation.

  • Workflow templates are not accessible for migration

    Hireology workflow templates defining stage sequences, automated actions, and approval gates are stored in the configuration layer and are not accessible via the public API. We cannot migrate them programmatically. We deliver a written inventory of every Hireology stage, configured action, and automation inferred from the customer's data and configuration, with a recommended Bullhorn equivalent. The customer's Bullhorn admin or implementation partner rebuilds these as Bullhorn Opportunity workflows or Bullhorn Automation Engine configurations post-migration. This is a significant admin investment that should be scoped before migration begins.

Migration approach

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

  1. Discovery and Hireology record sampling

    We audit the source Hireology account across all accessible objects: Jobs, Candidates, Applications, Locations, Users, and any custom fields discovered via record sampling. We sample at minimum 50 Job records, 50 Candidate records, and 50 Application records, comparing each against the standard Hireology schema to build the custom field delta list. We document the interview scorecard rubric variants in use, the location count, and any background check or SkillSurvey data attached to Candidate records. The discovery output is a written migration scope with object-level mapping, custom field inventory, and a Bullhorn edition recommendation based on the required custom object count.

  2. Bullhorn custom object provisioning coordination

    If the migration requires Bullhorn custom objects beyond what the destination edition supports, we coordinate with the customer to submit Bullhorn Support tickets for custom object creation before migration begins. Bullhorn requires a setup spreadsheet per custom object. We assist the customer in completing the spreadsheet with the field name, type, required/optional, and display configuration for each field. Bullhorn Support lead time for custom object provisioning varies; we begin this step in parallel with schema design to avoid blocking the migration timeline.

  3. Schema design and scorecard rubric normalization

    We design the Bullhorn destination schema: JobOrder fields, Candidate fields, JobSubmission fields, and any custom objects commissioned from Bullhorn Support. We map Hireology Locations to ClientCorporation or location custom fields based on the customer's Bullhorn use case. We normalize interview scorecard rubrics to a single target format agreed upon during scoping. We create the uniform scorecard template in Bullhorn and document which Hireology rubrics map to which target fields. Schema is validated in a Bullhorn Sandbox if available before production migration begins.

  4. Sandbox migration and reconciliation

    We run a full migration into a Bullhorn Sandbox using production-like data volume. The customer's team reconciles record counts (Jobs in, Candidates in, Applications in, Locations in), spot-checks 25-50 random records against the Hireology source, and reviews the interview scorecard normalization output. Any mapping corrections or scorecard field adjustments happen in the Sandbox before production migration begins. Background check metadata and custom field mappings are verified during this phase.

  5. User provisioning and Owner reconciliation

    We extract every distinct Hireology user (hiring managers, recruiters, admins) and match them by email against the Bullhorn destination org's User table. Any Hireology user without a matching Bullhorn User goes to a reconciliation queue. The customer's Bullhorn admin provisions missing users and assigns roles and Permission Sets before record migration resumes. OwnerId references on JobOrder, Candidate, and JobSubmission require resolved User records before import can proceed.

  6. Production migration in dependency order

    We run production migration in record-dependency order: Users (validated), ClientCorporations (from Hireology Locations if applicable), JobOrders (from Hireology Jobs with location association), Candidates, JobSubmissions (from Hireology Applications with parent JobOrder and Candidate resolved), interview scorecards (to Notes or custom scorecard object), background check metadata (to Candidate fields or custom object), and custom fields (last, after Bullhorn custom object schema is confirmed). Each phase emits a row-count reconciliation report before the next phase begins.

  7. Cutover, validation, and workflow rebuild handoff

    We freeze Hireology 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 Workflow Template inventory document to the customer's admin team with recommended Bullhorn equivalents. We flag background check re-initiation requirements per candidate. We support a one-week hypercare window where we resolve any reconciliation issues. We do not rebuild Hireology workflows as Bullhorn Automation Engine configurations inside the migration scope; that is a separate engagement.
