Overview

What this migration involves

Migrating from BambooHR to Bullhorn is a platform-category transition from an HRIS to a staffing-focused ATS and CRM. The two systems share a Contact-like entity, but BambooHR organizes around Employees (current staff, employment history, compensation, PTO), while Bullhorn organizes around Candidates, ClientCorporations, JobOrders, and Placements. We migrate the overlapping record types — BambooHR Applicants to Bullhorn Candidates, BambooHR Employee contact fields to Bullhorn Contact records, and any applicant-stage candidates — and flag what cannot map because Bullhorn's data model is purpose-built for the staffing placement lifecycle, not HR record-keeping. Bullhorn's custom import tool limits to 1,000 records per batch for Candidates, Contacts, and Leads; larger migrations require our API pipeline with Bullhorn REST API batch handling and rate-limit backoff. Workflows, BambooHR onboarding checklists, and payroll data do not migrate; we deliver a written inventory for admin rebuild.

Why teams make this switch

Two sides of the same decision

Leaving

BambooHR

What's pushing teams away

  • Companies over 150–200 employees report hitting platform ceilings — limited customization, weaker advanced reporting, and fewer enterprise controls become blockers at scale.
  • Limited mobile functionality compared to the desktop version frustrates field or remote workers who need to request time off or update information on the go.
  • Customization gaps in managing PTO rules and user profiles create friction for HR admins with non-standard accrual policies or complex org structures.
  • Missing features for more sophisticated use cases — advanced performance workflows, deep configurability, and granular permissions are commonly cited as gaps.
  • Competitors like Rippling and Workday are perceived as offering broader platform capabilities, prompting migration searches when companies outgrow BambooHR's scope.

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 BambooHR objects map to Bullhorn ATS & CRM

Each row shows how a BambooHR 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.

BambooHR

Employee

maps to

Bullhorn ATS & CRM

Contact or Candidate (split required)

1:many
Fully supported

BambooHR Employee records split into two Bullhorn targets depending on employment lifecycle stage. Employees who are currently active candidates for new roles (internal mobility, secondments, or sourcing candidates) map to Bullhorn Candidate records. Employees being recorded as placed staff from a prior agency engagement map to Bullhorn Contact records attached to a ClientCorporation. The split rule is defined during scoping based on the customer's use case — internal mobility cases go to Candidate; agency placement records go to Contact. Basic name, email, phone, address, and emergency contact fields migrate directly; BambooHR employment status, termination date, and hire date are stored as custom fields on the Bullhorn record because Bullhorn's standard fields are recruitment-focused.

BambooHR

Applicant

maps to

Bullhorn ATS & CRM

Candidate

1:1
Fully supported

BambooHR ATS Applicant records map directly to Bullhorn Candidate. Pipeline stage names (Applied, Phone Screen, Interview, Offer, Hired, Rejected) from BambooHR map to Bullhorn Candidate status and leadStatus fields, with manual mapping per customer because BambooHR pipeline stages are customer-defined. Resume files attached to BambooHR applicants migrate as Bullhorn Candidate resumes (file upload via Bullhorn REST API or document management). Custom application fields from BambooHR (any field beyond name, email, phone, resume, and stage) migrate as Bullhorn custom fields on the Candidate entity, with field type validation against Bullhorn's supported types (text, number, date, dropdown, multi-select, checkbox).

BambooHR

Job Information

maps to

Bullhorn ATS & CRM

JobOrder

1:1
Fully supported

BambooHR job postings in the ATS layer map to Bullhorn JobOrder records. BambooHR job title, job description, employment type (full-time, part-time, contract), and location map to Bullhorn JobOrder title, description, employmentType, and addressCity/addressState fields. The BambooHR job status (Open, Filled, Closed) maps to Bullhorn JobOrder status (Open, Interviewing, Offer, Closed, Cancelled). Any BambooHR custom job fields migrate as custom fields on Bullhorn JobOrder.

BambooHR

Job Application

maps to

Bullhorn ATS & CRM

CandidateSubmission or Placement (conditional)

lossy
Fully supported

BambooHR applications (Applicant-to-Job associations with application date, source, and custom fields) map to Bullhorn CandidateSubmission when the candidate is submitted to a job but not yet placed, and to Bullhorn Placement when the candidate is hired into the role. The mapping type is conditional based on BambooHR application status. Placements carry startDate, endDate, payRate, billRate, and client assignment — these map from BambooHR offer details and employment terms fields.

BambooHR

Employee

maps to

Bullhorn ATS & CRM

User (owner resolution)

1:1
Fully supported

BambooHR Employee records that have an email address matching an existing Bullhorn User account resolve to that User record for OwnerId assignment on Candidate, JobOrder, and Placement records. BambooHR employees without a Bullhorn User account go into a reconciliation queue; the customer's Bullhorn admin provisions User accounts for those employees before record import resumes. This is a prerequisite step before Candidate import can proceed because Bullhorn requires a non-null OwnerId on record creation.

BambooHR

Time-Off

maps to

Bullhorn ATS & CRM

Custom Field or Task

1:1
Fully supported

BambooHR time-off balances (accrued PTO, sick leave, personal days) and request history have no native Bullhorn equivalent because Bullhorn is an ATS, not an HRIS. We map time-off balances as Bullhorn custom fields on the Candidate or Contact record (if the customer uses Bullhorn for internal staffing and wants to track candidate availability). Time-off request history migrates as Task records with a custom type field for audit purposes, but Bullhorn does not enforce or process these as active policies.

BambooHR

Benefits Administration

maps to

Bullhorn ATS & CRM

Custom Field

1:1
Mapping required

BambooHR benefits enrollment data (health plan, dental, vision, 401k, HSA, FSA) is stored per Employee with customer-specific schema variation. We map benefits data as Bullhorn custom fields on the Candidate or Contact record if the customer wants to carry benefit election history. Benefits carrier names, plan tiers, and coverage effective dates migrate as text and date fields. This is flag scope — many BambooHR benefit exports contain carrier-specific plan codes that do not map to Bullhorn standard fields and require a manual review step during scoping.

BambooHR

Compensation

maps to

Bullhorn ATS & CRM

Custom Field

1:1
Fully supported

BambooHR pay rate, pay type (salary, hourly, exempt), pay frequency, and currency map to Bullhorn custom fields on the Candidate record (for current/past pay) and Placement record (for bill rate and pay rate on placed candidates). BambooHR compensation grades and bands are customer-specific data that we map to Bullhorn custom fields or custom objects as appropriate. Bullhorn's standard compensation fields are placement-focused (billRate, payRate) rather than employment-focused, so we use Bullhorn's custom field infrastructure for pay history.

BambooHR

Custom Employee Fields

maps to

Bullhorn ATS & CRM

Custom Fields

lossy
Mapping required

BambooHR's per-account custom fields (any field not in the standard employee schema) require a Bullhorn custom field to be created before migration data can land. Bullhorn requires a Support ticket to create a new custom object, but custom fields on existing entities (Candidate, JobOrder, ClientCorporation, Placement) can be created by Bullhorn admins via Admin > Field Mappings. We create the Bullhorn custom field definitions during the pre-migration schema phase, validate field types against Bullhorn's supported types (text, number, date, dropdown, multi-select, checkbox, currency), and then map BambooHR values during data transform. Bullhorn has a per-entity limit on custom field count that we verify during scoping.

BambooHR

Performance Management

maps to

Bullhorn ATS & CRM

Custom Field or Note

1:1
Mapping required

BambooHR performance review cycles, review scores, and goals are not fully exposed in the standard employee export. We map review completion status and overall scores as Bullhorn custom fields on the Candidate or Contact record. Review text, feedback comments, and manager notes migrate as Bullhorn Note records linked to the Contact record. Detailed performance workflow history (multi-round review cycles, 360 feedback, goal trees) does not map to any Bullhorn standard object and is flagged as scope requiring admin rebuild or a third-party performance management integration.

BambooHR

Onboarding

maps to

Bullhorn ATS & CRM

Bullhorn Onboarding (Able)

1:1
Mapping required

BambooHR onboarding tasks, checklists, and document requests tied to new hires have no equivalent in Bullhorn ATS. Bullhorn Onboarding (the Able product, formerly a separate acquisition) handles candidate-facing onboarding after placement, not HR onboarding. We inventory BambooHR onboarding task names, checklist states, and document requests during scoping and deliver a written handoff document listing each task and its recommended Bullhorn Onboarding equivalent. The customer's Bullhorn admin or implementation partner rebuilds the onboarding workflow configuration post-migration.

BambooHR

Documents

maps to

Bullhorn ATS & CRM

ContentDocument

1:1
Mapping required

Documents attached to BambooHR employee records (offer letters, signed contracts, certifications, tax forms) migrate as Bullhorn ContentDocument records linked via ContentDocumentLink to the corresponding Candidate or Contact record. BambooHR document binary storage is accessed via the BambooHR API file endpoint; we retrieve each document by employee ID and upload to Bullhorn using the Bullhorn REST API. Document type classification (offer letter, contract, certification) maps to a custom ContentDocument Description field. Bullhorn's Custom Import tool does not handle documents — this is an API-level migration step.

Pair-specific challenges

  • BambooHR ATS and Bullhorn ATS serve different purposes, not a direct upgrade

    BambooHR's ATS module handles job postings and basic applicant tracking for companies hiring employees. Bullhorn is purpose-built for staffing agencies managing clients, job orders from clients, and high-volume candidate pipelines with placement billing. The data models diverge significantly: BambooHR tracks Employees, Employment History, Compensation, and PTO; Bullhorn tracks Candidates, ClientCorporations, JobOrders, Placements, and Invoices. We clearly scope which BambooHR records are candidate-like (Applicants, job-stage employees) versus employee-only (HR records, payroll, PTO), and we do not attempt to force HR data into Bullhorn's placement-focused schema.

  • Bullhorn's Custom Import caps at 1,000 records per batch for three entity types only

    Bullhorn's admin-level Custom Import tool imports up to 1,000 records per batch and supports only Candidate, Contact, and Lead entities. Companies, JobOrders, and Placements must be created separately (Company via API, JobOrder via API or manual, Placement via API). Migrations exceeding 1,000 records per entity require our Bullhorn REST API pipeline with batch chunking, rate-limit handling (50 requests per second burst, 500 per minute sustained), and retry logic. BambooHR's per-employee report exports have no batch constraints, so we handle the output side segmentation during data transform.

  • Bullhorn custom objects require a Bullhorn Support ticket, not admin self-service

    Unlike Bullhorn custom fields on standard entities (Candidate, JobOrder, ClientCorporation), which Bullhorn admins can create via Admin > Field Mappings, Bullhorn custom objects (customObject1s through customObject10s) require opening a Support ticket with Bullhorn to provision. This adds a pre-migration step that is outside our API pipeline. We include custom object provisioning in the scoping timeline and recommend the customer open the Support ticket as soon as the migration scope is signed, since Bullhorn's support SLA on custom object requests varies.

  • BambooHR API rate limits are undocumented, Bullhorn's are documented

    BambooHR's API documentation explicitly states that rate limits are not published and implementations should always be ready for 503 responses, with no stated per-minute or per-day ceiling. We monitor for 503 responses during export, implement exponential backoff with jitter, and proactively throttle our request pipeline if throttling patterns emerge. Bullhorn's API documents a 50 req/s burst and 500 req/min sustained limit with 429 responses and a Retry-After header. We use Bullhorn's documented limits for the import pipeline and BambooHR's adaptive approach (backoff on 503) for the export pipeline.

  • BambooHR onboarding and payroll data have no Bullhorn equivalent in standard scope

    BambooHR onboarding task lists, checklist states, and document request workflows do not migrate to Bullhorn Onboarding (Able) because Able handles candidate-facing onboarding post-placement, not HR onboarding. We inventory the BambooHR onboarding state per new hire and deliver a written handoff with task names, current states, and recommended Bullhorn Onboarding equivalents. Bullhorn Onboarding is a separate product activation and configuration not included in standard ATS scope. Similarly, BambooHR payroll data (pay stubs, tax withholding, direct deposit info, journal entries) has no Bullhorn equivalent; we flag payroll data as a manual reconciliation step with the customer's HR and finance teams.

Migration approach

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

  1. Scoping and platform classification

    We audit the BambooHR account across installed modules (HRIS, ATS, Payroll, Performance), record counts per object type (Employees, Applicants, Job Postings, Custom Fields, Benefits enrollments, PTO balances), and active onboarding workflows. We identify which records are candidate-like (Applicants in the BambooHR ATS layer, job-stage employees for internal mobility) versus HR-only (payroll, PTO, benefits, performance reviews). We pair this with a Bullhorn edition review (Starter at $99/user for 1-2 users, Core at $165/user for small growing teams, Pro tier-based for AI and automation features) to determine which Bullhorn features are available for the target schema. The scoping output is a written migration object inventory and Bullhorn edition recommendation.

  2. Schema provisioning and field mapping design

    We design the Bullhorn destination schema during this step. This includes creating Bullhorn custom fields on Candidate, JobOrder, ClientCorporation, and Placement entities via Admin > Field Mappings (for custom fields) and via Bullhorn Support ticket (for custom objects). We map BambooHR pipeline stage names to Bullhorn Candidate status values per customer configuration. We define the Employee-to-Candidate or Employee-to-Contact split rule based on the customer's use case. Bullhorn admin credentials and Field Mappings write access are required before this step proceeds.

  3. Sandbox migration and reconciliation

    We run a full migration into a Bullhorn sandbox environment (or a named subset of the production database if no sandbox is available) using representative data volume. The customer's Bullhorn admin reconciles record counts (Candidates in, Contacts in, JobOrders in, Placements in), spot-checks 25-50 random records against the BambooHR source for field accuracy, and validates custom field data. Any mapping corrections — wrong field types, missed custom fields, stage name mismatches — happen here before production migration begins. This step also validates that Bullhorn's field-level security and validation rules do not block the import batch.

  4. Owner and User reconciliation

    We extract every distinct BambooHR employee with an email address who is referenced as an owner or hiring manager on a BambooHR Applicant, Job Posting, or Employee record. We match these by email against Bullhorn's User table in the destination org. BambooHR employees without a matching Bullhorn User go to a reconciliation queue. The customer's Bullhorn admin provisions any missing User accounts before production migration proceeds. Bullhorn requires a non-null OwnerId on Candidate, JobOrder, and Placement records — migration cannot proceed past this step without owner resolution.

  5. Production migration in dependency order

    We run production migration in record-dependency order: Bullhorn Users (manual, validated in step 4), ClientCorporations (from any employer/agency client data in BambooHR), JobOrders (from BambooHR job postings), Candidates (from BambooHR Applicants and split Employee records), Placements (for hired applicants with employment terms), then custom fields and documents. Bullhorn's Custom Import tool (up to 1,000 records per batch for Candidates, Contacts, Leads) handles records within the limit; records exceeding the batch cap migrate via Bullhorn REST API with rate-limit handling. Each phase emits a row-count reconciliation report before the next phase begins.

  6. Cutover, validation, and onboarding rebuild handoff

    We freeze BambooHR write access during the cutover window, run a final delta migration for any records modified during the migration window, then enable Bullhorn as the system of record for recruiting operations. We deliver the onboarding task inventory document to the customer's Bullhorn admin. We support a one-week hypercare window where we resolve any reconciliation issues raised by the recruiting team. We do not configure Bullhorn Onboarding (Able) workflows, Bullhorn Automation (Herefish) sequences, or Bullhorn payroll integrations inside the migration scope; those are separate product activations or implementation engagements.

Platform deep dives

Context on both ends of the pair

BambooHR logo

BambooHR

Source

Strengths

  • Single platform consolidating ATS, onboarding, HR records, payroll, and time-off reduces system sprawl for SMBs.
  • Fast implementation — BambooHR reports four to six weeks from kickoff to go-live for most customers.
  • Per-employee pricing with automatic volume discounts makes cost predictable as headcount grows.
  • Strong customer support reputation (Support Heroes) cited consistently across G2, Capterra, and direct testimonials.
  • Well-documented API with UTF-8 encoding, clear field types, and HTTPS-only access.

Weaknesses

  • Mobile application is significantly limited compared to the desktop experience, frustrating remote and field workers.
  • Companies above 150–200 employees frequently outgrow the platform's feature depth and customization surface.
  • Limited advanced reporting and analytics compared to enterprise HR platforms — custom report building is the ceiling.
  • PTO and profile customization are pain points — non-standard accrual policies and complex org structures require workarounds.
  • Document management and attachment handling lack the granularity of dedicated document-centric HR systems.

Most migrations land between four and eight weeks for accounts with fewer than 5,000 candidate and contact records and no complex ATS pipeline history. Migrations that include full BambooHR ATS pipeline data (hundreds of application records with stage history, multiple job postings, and extensive custom fields on Candidates) move to ten to fourteen weeks because Bullhorn's batch import cap of 1,000 records per run requires API-level chunking and the Employee-to-Candidate or Employee-to-Contact split adds reconciliation work. Bullhorn's own onboarding documentation cites two to six weeks for standard agency implementations; our migration timeline is additive to that baseline for data that does not fit Bullhorn's standard import paths.
