Overview

What this migration involves

Moving from Bullhorn ATS & CRM to BambooHR is a category-crossing migration from a staffing-agency ATS+CRM to a people-centered HCM platform. Bullhorn's data model is built around Candidates, JobOrders, Clients, Opportunities, and Placements serving a recruitment-sales workflow. BambooHR's model centers on Employees, Applicants, Jobs (internal postings), Time Off, and Benefits. We extract the subset of Bullhorn records that map to BambooHR objects—primarily Candidate profiles that become Employees or Applicants, historical placement records that become employment history entries, and User records that become BambooHR system accounts—and flag every object that cannot migrate because it has no BambooHR equivalent (Client corporations, Opportunities, Placements for contract billing, JobOrders as external job postings). We deliver a written inventory of unmigratable Bullhorn records for the customer's records-retention policy. Bullhorn ATS Growth edition's lack of API access and the attachment-export limitation from CSV bulk exports are primary migration risk factors we identify during scoping.

Why teams make this switch

Two sides of the same decision

Leaving

Bullhorn ATS & CRM logo

Bullhorn ATS & CRM

What's pushing teams away

  • The interface is widely described as old, bloated, and unintuitive with a steep learning curve that frustrates new users and slows recruiter adoption during onboarding.
  • Slow performance and page load lag appear in over 200 G2 reviews, making the platform feel unresponsive during high-volume recruiting days.
  • Pricing is opaque and negotiated individually with significant implementation fees, making it difficult to budget and compare against alternatives with published pricing.
  • Limited customization relative to modern CRM platforms constrains agencies that want to tailor workflows to niche or non-standard recruiting processes.

Choosing

BambooHR logo

BambooHR

What's pulling them in

  • Lowest friction entry point for SMBs moving off spreadsheets — intuitive interface means most teams are functional within days, not weeks.
  • Consolidation value: BambooHR merges ATS, onboarding, HR records, time-off, and payroll into a single pane of glass that employees never need to leave.
  • Volume discounts applied automatically by headcount, so pricing scales predictably as the company grows without renewal negotiations.
  • BambooHR reports most customers go live in four to six weeks, making it a realistic commitment for under-resourced HR teams.
  • Award-winning Support Heroes cited frequently in reviews — responsive human support after implementation is a differentiator.

Object mapping

How Bullhorn ATS & CRM objects map to BambooHR

Each row shows how a Bullhorn ATS & CRM object lands in BambooHR, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Bullhorn ATS & CRM

Candidate

maps to

BambooHR

Employee or Applicant

1:many
Fully supported

Bullhorn Candidate records split into two BambooHR destinations. Candidates with a Placement record (hired through the staffing agency) become BambooHR Employees with start dates from the Placement record. Candidates without a Placement but with job submission history become BambooHR Applicants in the BambooHR ATS module. The candidate name, email, phone, address, resume file reference, parsed skills, work history (education, employment), and custom fields migrate to the corresponding BambooHR Employee or Applicant field. Historical salary information from Placement payRate fields maps to BambooHR custom pay-rate fields on Employee.

Bullhorn ATS & CRM

Candidate (work history)

maps to

BambooHR

Employee: Employment History

1:1
Fully supported

Bullhorn Candidate employment history (from resume parse) maps to BambooHR Employee employment history entries. Each Bullhorn employment record (company name, title, start date, end date, description) becomes a separate BambooHR Employment History item. Date precision from Bullhorn may exceed BambooHR's field granularity; we normalize to month-year format where BambooHR does not support exact dates.

Bullhorn ATS & CRM

Placement

maps to

BambooHR

Employee (custom fields)

lossy
Fully supported

Bullhorn Placement records carry the pay rate (candidate pay), charge rate (client bill rate), start date, end date, and overtime eligibility flag. These do not map to a native BambooHR object because BambooHR has no staffing-billing model. We map Placement fields to custom Employee-level fields: payRate__c, chargeRate__c, contractStartDate__c, contractEndDate__c, overtimeEligible__c. If the customer no longer manages contractors this way, we recommend archiving Placement records to a CSV inventory rather than populating custom fields.

Bullhorn ATS & CRM

User (Recruiter/Owner)

maps to

BambooHR

User

1:1
Fully supported

Bullhorn User records (recruiters, sales staff, administrators) map to BambooHR User accounts for the HR administrators who will manage the BambooHR system. We resolve by email match. Bullhorn Users who were external recruiters or contract staffing consultants have no equivalent in BambooHR and are excluded from the user migration scope. Active/inactive status migrates from Bullhorn isDeleted flag.

Bullhorn ATS & CRM

JobOrder

maps to

BambooHR

No equivalent

1:1
Fully supported

Bullhorn JobOrder records (external job postings for staffing assignments) have no direct BambooHR equivalent. BambooHR Jobs represent internal company positions open for hire, not external job postings for client-funded staffing assignments. We do not migrate JobOrders. We deliver a written inventory of all Bullhorn JobOrders with their status, requirements, and location as a CSV for the customer's records-retention file. If the customer is transitioning from external staffing to internal hiring, internal open positions should be created manually in BambooHR after migration.

Bullhorn ATS & CRM

Client (ClientCorporation)

maps to

BambooHR

No equivalent

1:1
Fully supported

Bullhorn Client records represent the staffing agency's customer companies—business entities with primary contacts, industry classification, and address. BambooHR has no Client or company-account concept; it manages people (employees), not business relationships. Client records cannot migrate. We deliver a written inventory of all Bullhorn Clients with contact name, company, email, and phone as a CSV for the customer's CRM migration if they adopt a separate CRM post-Bullhorn.

Bullhorn ATS & CRM

Contact

maps to

BambooHR

Employee or Emergency Contact

1:many
Fully supported

Bullhorn Contact records serve two roles: client-side business contacts (associated with Client records) and candidate references. Business contacts do not map to BambooHR. Candidate reference contacts (professional references listed on a Candidate profile) map to the corresponding BambooHR Employee as Emergency Contact or Reference records with name, relationship, phone, and email.

Bullhorn ATS & CRM

Opportunity

maps to

BambooHR

No equivalent

1:1
Fully supported

Bullhorn Opportunities represent recruiting pipeline deals tied to Clients—sales CRM stages like Qualified, Interview, Offer, Placed. BambooHR has no pipeline, deal, or sales-stage concept. Opportunity records cannot migrate. We deliver a written inventory of all Bullhorn Opportunities with their status, stage, value, and associated Client as a CSV. If the customer maintains a separate CRM post-Bullhorn, this CSV serves as the seed data for re-entering pipeline history.

Bullhorn ATS & CRM

Task

maps to

BambooHR

Note (Employee)

1:1
Fully supported

Bullhorn Tasks (to-dos with type, due date, status, and owner assignment) map to BambooHR Note records attached to the corresponding Employee. Task type maps to a Note category field; due date and status become note body content. Open tasks (Status = Open) migrate as active notes for the employee's BambooHR record; completed tasks migrate as historical notes. Bullhorn task ownership resolves via the User-to-Employee mapping before note creation.

Bullhorn ATS & CRM

CandidateList (Job Submission)

maps to

BambooHR

Applicant: Application History

1:1
Fully supported

Bullhorn CandidateList records represent a Candidate's submission to a specific JobOrder with a status in the recruitment pipeline (Submitted, Interview, Offer, etc.). When the candidate maps to a BambooHR Applicant, the CandidateList submission history migrates as Application History notes on the Applicant record, preserving the original submission date, job title, and stage status.

Bullhorn ATS & CRM

Custom Object

maps to

BambooHR

Custom Field

lossy
Fully supported

Bullhorn custom objects (up to 2 on ATS editions, 10 on Front Office) extend core entities with up to 55 fields each. BambooHR supports custom fields on Employee and Applicant records but does not support standalone custom objects. We audit every Bullhorn custom object used on Candidate records during scoping. Fields that map to existing BambooHR Employee fields are redirected; overflow fields are mapped to BambooHR custom fields. If the count of custom fields per entity exceeds BambooHR's practical limit (roughly 20 custom fields per object), we recommend rationalizing or archiving the overflow before migration.

Pair-specific challenges

  • Bullhorn ATS Growth edition has no API access

    Bullhorn's ATS Growth edition (formerly Team Edition) explicitly excludes API access. Any migration scoped against a Growth-tier Bullhorn instance cannot use the REST API for data export. We must rely on CSV bulk exports or a manual export workflow. Bullhorn's standard CSV export does not include file attachments, custom object data, or engagement history in a single file—it requires multiple list-view exports that must be joined by record ID. We identify the customer's Bullhorn edition during scoping and adjust the migration approach accordingly. If API access is unavailable, we budget additional time for manual export assembly and flag that attachment migration becomes batch-download via the Bullhorn UI rather than API retrieval.

  • Staffing-specific objects have no BambooHR equivalent

    Bullhorn Client corporations, Opportunities, JobOrders, and Placements represent the core of a staffing agency's data model. BambooHR has no CRM module, no pipeline or deal-tracking, no external job-posting concept, and no staffing-billing model. These records cannot migrate and will be excluded from the BambooHR import. We deliver a written inventory of every unmigratable record as a structured CSV for the customer's records-retention file, including the record type, key fields, and any dependent relationships that the customer may need to reference later. If the customer requires CRM functionality post-Bullhorn, we recommend a separate CRM migration scope.

  • Resume attachments excluded from CSV bulk exports

    Bullhorn's standard list-view CSV export does not include file attachments. Resume files, parsed documents, and uploaded communications exist as separate file-reference objects accessible only via the REST API. If the migration uses CSV-only exports (due to Growth edition lacking API access), every resume and attachment will be silently omitted from the BambooHR import. We always include explicit attachment-migration steps in Bullhorn migration scopes and use Bullhorn's file reference API endpoints to retrieve originals when API access is available. When only CSV export is possible, we budget manual attachment download via the Bullhorn UI and flag the additional labor cost.

  • Bullhorn custom object fields may exceed BambooHR's practical limit

    Bullhorn allows up to 55 fields per custom object, and organizations on Front Office editions can have 10 searchable custom objects per entity. BambooHR supports custom fields on Employee and Applicant records but has a practical soft ceiling of approximately 20 custom fields per object before the Employee setup interface becomes unwieldy. When Bullhorn Candidate records use multiple custom objects with a high field count, we audit all custom object usage during scoping, identify fields that map to standard BambooHR fields, and recommend archiving or consolidating overflow fields before migration. This rationalization step adds scope and timeline if custom object usage is heavy.

  • Opportunity stage history cannot be preserved in BambooHR

    Bullhorn Opportunities carry a recruitment-specific stage history—Pipeline, Qualified, Interview, Offer, Extended, Placed—that represents the sales pipeline for staffing assignments. BambooHR has no pipeline or opportunity-tracking model. Even if we could import opportunity stage data, there is nowhere to display it within BambooHR's standard employee and applicant records. We do not attempt to force opportunity history into BambooHR as a workaround (e.g., as notes or custom fields) because it creates misleading context for HR administrators who expect BambooHR to manage people, not recruiting pipelines. We document opportunity stage history in the written inventory CSV and recommend a separate CRM migration scope if the customer needs to preserve it.

Migration approach

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

  1. Discovery and edition identification

    We audit the source Bullhorn instance across edition tier (Growth/ATS/Corporate/Front Office), API availability, record counts by object (Candidates, Placements, Users, Contacts, JobOrders, Opportunities, Custom Objects), custom object field inventory, and engagement volume. We identify whether the Bullhorn REST API is accessible and whether any third-party integrations (Bullhorn Back Office, Bullhorn Onboarding) are active and must be decommissioned before migration. The discovery output is a written migration scope that explicitly lists migratable objects, unmigratable objects, and the inventory plan for each category.

  2. Schema mapping and custom field design

    We design the destination BambooHR schema. This includes mapping Bullhorn Candidate fields to BambooHR Employee and Applicant fields, designing the BambooHR custom fields to receive Placement billing data (payRate__c, chargeRate__c, contractStartDate__c, contractEndDate__c) and any Bullhorn custom object fields that cannot map to standard BambooHR fields, and identifying which Bullhorn custom object fields have direct BambooHR equivalents to avoid unnecessary custom field proliferation. We coordinate with the customer's BambooHR admin to confirm custom field creation permissions and naming conventions before deployment.

  3. Bullhorn data export

    We export Bullhorn data in dependency order: Users first (to resolve the user-to-employee mapping), then Candidates with their associated CandidateLists, then Placements with their linked pay/charge rates, then Tasks and Attachments. On ATS Growth editions where API access is unavailable, we assemble CSV exports by object and manually join them by record ID. We retrieve file attachments via Bullhorn's file reference API endpoints or via batch UI download. We flag any records where Bullhorn's parsed resume data is incomplete (due to non-standard resume formatting or missing parse fields) and restore from the original file reference where parse data is missing.

  4. Employee and Applicant import

    We import into BambooHR in record-dependency order: Employees first (from Bullhorn Candidates with Placement records, using the Placement start date and custom billing fields), then Applicants (from Bullhorn Candidates without Placement records or with CandidateList submission history). Bullhorn User records map to BambooHR User accounts for the HR system administrators. Each phase emits a row-count reconciliation report. We validate that the BambooHR Employee ID generated for each migrated record is captured for use in any downstream note and attachment linking.

  5. Attachment migration and note linking

    We migrate Bullhorn resume attachments and parsed documents as BambooHR Employee or Applicant documents. We resolve the target BambooHR record by matching the Bullhorn Candidate email to the newly created Employee or Applicant. Resume files are uploaded as BambooHR document attachments with the document type set to Resume. Any Bullhorn Task records are imported as BambooHR Note records linked to the corresponding Employee. We validate that every document attachment has a matching BambooHR record before marking the phase complete.

  6. Cutover, validation, and unmigratable inventory delivery

    We freeze Bullhorn write access during cutover, run a final delta migration of any records modified during the migration window, then enable BambooHR as the system of record. We validate record counts, spot-check 20-30 random employee records against the Bullhorn source data, and confirm attachment coverage. We deliver the written inventory of unmigratable Bullhorn records (JobOrders, Clients, Opportunities, Placements without billing context) as structured CSVs with field-level documentation for the customer's records-retention policy. We support a one-week hypercare window for reconciliation issues. We do not rebuild Bullhorn workflows or automations in BambooHR; those are documented separately as a BambooHR automation rebuild plan for the customer's admin.

Most migrations land between two and four weeks for organizations with fewer than 5,000 Candidate records and API-accessible Bullhorn editions. Migrations requiring CSV-only export due to Bullhorn Growth edition lacking API access, or involving heavy custom object usage that requires field rationalization, extend to five to nine weeks. The primary time drivers are manual export assembly on Growth editions, attachment batch retrieval, custom field design and testing, and the rationalization step if Bullhorn custom objects exceed BambooHR's practical custom field limit.
