Overview

What this migration involves

LogicMelon and Bullhorn take fundamentally different approaches to the candidate record. LogicMelon stores applications as separate entities under each job, meaning the same person applying to three jobs produces three distinct LogicMelon application records. Bullhorn maintains one unified Candidate record linked to multiple JobSubmission records. We resolve this structural difference during migration: we deduplicate by candidate email and phone, create a single Bullhorn Candidate, and generate a JobSubmission per original LogicMelon application tied to the correct JobOrder. The list of job boards targeted per LogicMelon job advert is preserved as Bullhorn tags so your team retains the original posting distribution without re-entering it manually. CV files migrate as binary attachments on the Candidate record. Bullhorn's 191 integrations (versus LogicMelon's 6) and native CRM functions are available from day one. We do not migrate LogicMelon job board posting configurations, multi-posting schedules, or distribution rules; these are documented for your team to rebuild directly in Bullhorn or re-enable the LogicMelon integration from Bullhorn's Marketplace.

Why teams make this switch

Two sides of the same decision

Leaving

LogicMelon

What's pushing teams away

  • Editing an existing live job post can take a long time to propagate changes, particularly when the advertisement needs reformatting after the initial posting went live.
  • Posting latency varies by job board — some boards update within minutes while others take significantly longer, creating inconsistent candidate response windows.
  • Users report that third-party job board search results can behave unexpectedly with new contracts, introducing friction when sourcing across newly activated boards.
  • The interface becomes laggy under heavy multi-board posting loads, particularly when managing large volumes of concurrent job adverts and candidate records.

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 LogicMelon objects map to Bullhorn ATS & CRM

Each row shows how a LogicMelon 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.

LogicMelon

Job

maps to

Bullhorn ATS & CRM

JobOrder

1:1
Fully supported

LogicMelon Jobs map directly to Bullhorn JobOrder records. The job advert content (title, description, requirements, salary) migrates to Bullhorn's title, description, and publicDescription fields. Bullhorn JobOrder does not replicate the multi-posting action; instead, we preserve the list of targeted job boards from LogicMelon's per-job board-association list as Bullhorn tags on the JobOrder record. The original job reference ID from LogicMelon is stored in a custom field lm_job_id__c for audit and reconciliation.

LogicMelon

Application

maps to

Bullhorn ATS & CRM

Candidate + JobSubmission (split required)

1:many
Fully supported

LogicMelon Application records are the structural pivot point in this migration. Each LogicMelon Application references one Candidate and one Job. Bullhorn maintains a single Candidate record linked to multiple JobSubmission records (one per job applied to). We deduplicate LogicMelon Applications by candidate email and phone during extraction, create one Bullhorn Candidate, and generate a JobSubmission for each original application tied to the corresponding JobOrder. The application status (Applied, Screened, Interviewed, Offered, Placed) migrates to JobSubmission status with a reference back to the original LogicMelon application date and status transition history.

LogicMelon

Candidate

maps to

Bullhorn ATS & CRM

Candidate

1:1
Fully supported

LogicMelon Candidate profiles (name, email, phone, skills, work history, location) map to Bullhorn Candidate. The Bullhorn Candidate is the canonical record created in the Application split step above. Structured profile fields migrate to typed Bullhorn Candidate fields; any fields that do not map directly become custom fields pre-created in Bullhorn before import. The original candidate reference lm_candidate_id__c is stored for reconciliation.

LogicMelon

CV / Resume

maps to

Bullhorn ATS & CRM

Candidate (file attachment)

1:1
Fully supported

LogicMelon stores CVs as binary file attachments (PDF, DOCX) linked to Application or Candidate records. We extract the raw file and attach it to the Bullhorn Candidate record using Bullhorn's file attachment API. The CV file name and upload date are preserved. Bullhorn's resume parsing runs on the file after attachment, populating Bullhorn's standard resume fields (education, employment history, skills). We do not parse or transform CV content during extraction; the file is the source-of-truth backup where structured fields are incomplete.

LogicMelon

Company / Client

maps to

Bullhorn ATS & CRM

ClientCorporation

1:1
Fully supported

LogicMelon organisation or client records map to Bullhorn ClientCorporation. If LogicMelon stores staffing-client details alongside candidate records, these migrate as ClientCorporation with billing contact, address, and industry. ClientCorporation is created before Candidate import so that the client reference on JobOrder is satisfied at insert time.

LogicMelon

Job Board (per-job association)

maps to

Bullhorn ATS & CRM

JobOrder tag

1:1
Fully supported

LogicMelon stores the list of targeted job boards as a per-job board-association object rather than a global posting template. Bullhorn has no native per-job board list object; we preserve this as Bullhorn tags on the JobOrder record (one tag per targeted board). Tags are created from the LogicMelon board list at migration time and appear on the JobOrder in Bullhorn. The multi-posting action itself is not replicated; tags serve as a record of original posting distribution for audit and reporting.

LogicMelon

Screening Notes

maps to

Bullhorn ATS & CRM

Note / Comment

1:1
Mapping required

Recruiter screening notes, scoring, and evaluation comments attached to LogicMelon Applications migrate to Bullhorn Note records linked to the corresponding JobSubmission or Candidate. Bullhorn Note supports text content with timestamps and owner attribution. The original note type (screening score, shortlist reason, client feedback) is preserved in the note body or in a custom field lm_note_type__c if a structured type field exists in LogicMelon.

LogicMelon

Pipeline Stage

maps to

Bullhorn ATS & CRM

Opportunity workflow or JobSubmission status (configuration)

lossy
Fully supported

LogicMelon's configurable pipeline stages (Applied, Screened, Interviewed, Offered, Placed) map to Bullhorn JobSubmission status values. We extract the customer's specific stage name configuration during discovery, map each stage to the nearest Bullhorn status, and configure Bullhorn's JobSubmission status picklist accordingly. Any custom stage names that have no Bullhorn equivalent are added as custom status values or preserved in lm_stage_name__c on the JobSubmission.

LogicMelon

User / Recruiter

maps to

Bullhorn ATS & CRM

User

1:1
Fully supported

LogicMelon Users are tied to the organisation hierarchy via API credentials (EMEA or US instance, scoped to sub-unit). We extract every User referenced on Jobs, Applications, and Notes, and match by email against Bullhorn's User table in the destination org. Users without a Bullhorn match enter a reconciliation queue for your admin to provision before record import resumes. Inactive LogicMelon users are mapped to inactive Bullhorn users to preserve historical assignment.

LogicMelon

Organisation / Sub-unit

maps to

Bullhorn ATS & CRM

Corporate User or Division

1:1
Fully supported

LogicMelon's multi-tenant hierarchy (agency-level versus client-level sub-units) maps to Bullhorn's Corporate User structure. If Bullhorn Enterprise or higher is in use, we map LogicMelon sub-units to Bullhorn Divisions. If Professional is the destination tier, we document the hierarchy for your admin to configure post-migration in Bullhorn's Settings > Corporate Structure.

LogicMelon

Talent Pool

maps to

Bullhorn ATS & CRM

Candidate List or PlacementSpecialty

1:1
Fully supported

LogicMelon talent pools (grouped candidate collections for active or passive sourcing) map to Bullhorn Candidate Lists. We extract the talent pool name, membership, and any pool-level notes, and create Bullhorn Candidate List records with the original members linked. Talent pool category or tag assignments migrate as Bullhorn Candidate tags for ongoing segmentation.

LogicMelon

Custom Field (Job / Application)

maps to

Bullhorn ATS & CRM

Custom Field

lossy
Fully supported

LogicMelon allows custom fields on Jobs and Applications. We identify all active custom fields during discovery, map them to Bullhorn custom fields on the corresponding entity (JobOrder, JobSubmission, or Candidate), and pre-create the Bullhorn schema (including field type, picklist values, and visibility settings) before migration begins. Any custom fields that exceed Bullhorn's field count limits per entity are flagged in the discovery report for your admin to resolve.

Pair-specific challenges

  • Application deduplication is required before Bullhorn import

    LogicMelon's job-centric model creates one Application record per candidate per job. If the same candidate applied to four different jobs, LogicMelon holds four Application records. Bullhorn expects one Candidate record with four JobSubmission entries. We deduplicate by matching candidate email (and phone as secondary key) before creating Bullhorn records. The original application date and status from each LogicMelon Application are preserved in the corresponding JobSubmission. Skipping deduplication produces duplicate Candidate records in Bullhorn that will fragment recruiter workflows and corrupt placement reporting.

  • EMEA and US API instances require correct routing before extraction

    LogicMelon operates two distinct API instances: api.logicmelon.co.uk for EMEA and APAC customers and api.usa.logicmelon.com for US customers. The documentation, endpoint structures, and authentication flows differ between instances. We determine the correct instance during scoping by checking the customer's account region and configure our connector to the matching base URL. If the wrong instance is targeted, authentication succeeds but all object queries return empty results and the migration stalls silently. This gotcha is specific to LogicMelon as a source and does not apply when migrating away from other ATS platforms.

  • Job board targeting lists do not migrate as live posting configurations

    LogicMelon stores the list of targeted job boards per job advert as a board-association object. Bullhorn does not have a native per-job board distribution list; it relies on Bullhorn Marketplace integrations (Broadbean, LogicMelon itself, or other distributors) for job board posting. We preserve the board list as Bullhorn tags on the JobOrder so your team retains a record of where each position was originally posted. However, the multi-posting action does not replay in Bullhorn automatically. Your team must either reconfigure posting directly in Bullhorn or re-enable the LogicMelon-Bullhorn integration from Bullhorn's Marketplace.

  • CV files must be extracted and re-attached; Bullhorn resume parsing runs post-import

    LogicMelon stores CVs as binary file attachments without a structured schema or extracted text field. We extract the raw file (PDF, DOCX) and attach it to the Bullhorn Candidate record. Bullhorn's built-in resume parser (Affinda or Textkernel integration) runs after attachment to populate structured Candidate fields. If LogicMelon's structured profile fields are incomplete or missing, the CV file is the primary source of candidate information. We do not guarantee full text extraction from CVs during migration; the file is migrated as-is and parsing is a post-import step. Any CVs stored in non-standard formats or password-protected are flagged and delivered as-is with a note in the migration report.

  • LogicMelon has no automation layer; Bullhorn Automation requires manual rebuild

    LogicMelon does not offer workflow automation, sequence tools, or engagement cadence features comparable to Bullhorn Automation. Because there is no automation layer to migrate, this is not a data-loss risk. However, if your team has configured any LogicMelon-specific posting rules, candidate ranking algorithms, or auto-response triggers, these do not exist as transferable code. We document any identified LogicMelon-specific configuration in the migration scope document for your team to rebuild in Bullhorn or through a Bullhorn Automation implementation partner.

Migration approach

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

  1. Discovery and instance routing

    We audit the LogicMelon instance type (EMEA vs US API base URL), the organisation hierarchy, and the data volume across Jobs, Applications, Candidates, CV files, talent pools, and custom fields. We identify the correct API endpoint and credentials scope required for the migration extraction. We also confirm the Bullhorn edition and API access credentials, validate the REST API endpoint, and check the Bullhorn entity limits and custom field allocation for the destination org. The discovery output is a written scope document with record counts, a preliminary object mapping, and a Bullhorn custom field creation checklist.

  2. Schema pre-creation in Bullhorn

    We create all required Bullhorn custom fields (lm_job_id__c, lm_candidate_id__c, lm_application_date__c, lm_stage_name__c, and any custom fields identified from LogicMelon's active configuration) before any data import begins. Bullhorn custom fields are created via the Bullhorn REST API or through the Admin > Field Mappings interface. If the destination org has already used all available custom field slots on any entity, we flag the constraint during discovery and the customer resolves it before migration proceeds. Candidate Lists for talent pool migration are also created during this phase.

  3. CV file extraction and deduplication pass

    We extract all CV binary files from LogicMelon and assign each to the corresponding candidate record. Simultaneously, we run the deduplication pass: Applications sharing the same candidate email and phone are grouped, one Bullhorn Candidate is created per group, and the original application date and status are recorded per JobSubmission. The deduplication output is a reconciliation report showing how many LogicMelon Application records collapse into each Bullhorn Candidate. Your team reviews and approves the deduplication logic before production migration begins.

  4. Sandbox migration and mapping validation

    We run a full migration into the Bullhorn Sandbox (Full Copy or Partial Copy) using the customer's actual data. The customer reconciles record counts against LogicMelon reports: Jobs in equals JobOrders in, Applications in equals JobSubmissions in, Candidate records reflect deduplication output, CV file count matches Candidate count, and job board tag count matches JobOrder count. Any field mapping corrections, custom field additions, or deduplication logic adjustments happen in the sandbox before production migration begins.

  5. Production migration in dependency order

    We run the production migration in this order: ClientCorporation records (from LogicMelon company/client data), JobOrder records (with job board tags applied), Candidates (with CV attachments), JobSubmissions (linked to Candidates and JobOrders), Notes (screening notes and comments on JobSubmissions), Candidate Lists (talent pools with member assignments), and Pipeline stage configuration. Owner resolution by email matches LogicMelon Users to Bullhorn Users; any unmatched owners are held in a reconciliation queue. Each phase emits a row-count reconciliation report before the next phase begins.

  6. Cutover, validation, and job board handoff

    We freeze writes to LogicMelon during cutover, run a final delta migration for any records modified during the migration window, then confirm Bullhorn as the system of record. We deliver the migration reconciliation report, the post-migration custom field inventory, and the job board targeting metadata document listing every original posting board per JobOrder. We do not reconfigure Bullhorn job board integrations or republish jobs to job boards; that work is handled by your team using Bullhorn's native posting tools or by re-enabling the LogicMelon-Bullhorn Marketplace integration. We support a one-week hypercare window for reconciliation issues.

Most LogicMelon to Bullhorn migrations land between three and five weeks for agencies with up to 5,000 jobs, 50,000 applications, and clean deduplication profiles. Migrations exceeding 15,000 jobs or 200,000 applications, or involving multiple LogicMelon sub-organisations, extend to six to twelve weeks because of CV extraction time, multi-pass deduplication, and EMEA or US API instance handling. Bullhorn's own onboarding (Bullhorn Launch and OnRamp) runs in parallel and typically completes within two weeks, meaning the data migration and Bullhorn platform onboarding can proceed concurrently rather than sequentially.
