Overview

What this migration involves

Dayforce and Bullhorn serve different stages of the employment lifecycle. Dayforce is a full-stack HCM platform managing payroll, benefits, time off, and workforce scheduling across the entire employment relationship. Bullhorn is an ATS and recruitment CRM built to track candidates, job orders, and placements from first submission through hire. These platforms share a workforce data vocabulary but diverge sharply on scope: Dayforce holds the employment record; Bullhorn holds the recruiting pipeline. We bridge that gap by mapping Dayforce Workers to Bullhorn Candidates, Job Assignments to Job Orders, and building custom objects in Bullhorn for historical pay rates, earning groupings, and benefits enrollments that have no native Bullhorn equivalent. We do not migrate payroll, benefits carrier feeds, time and attendance data, or Dayforce Position Management hierarchies as these require specialized payroll and HRIS infrastructure that Bullhorn does not provide. Workflows, automations, and Dayforce-specific compliance configurations do not migrate; we deliver a written inventory of these for the customer's Bullhorn admin to rebuild in Bullhorn Automation.

Why teams make this switch

Two sides of the same decision

Leaving

Dayforce logo

Dayforce

What's pushing teams away

  • Customer support is cited as frustrating and unhelpful in nearly 60 G2 reviews — escalation paths are unclear and resolution times disappoint enterprise buyers.
  • Reporting tools are limited and help articles are described as outdated, making it difficult for HR teams to build custom reports without vendor assistance.
  • Large organizations find the sheer breadth of features overwhelming — too many modules, too many reports, and a steep learning curve for administrators.
  • Clock-in and clock-out functionality occasionally fails due to location or GPS errors, creating time and attendance discrepancies that fall on HR to manually correct.
  • Schedule entry is week-by-week only — managers cannot build an entire employee's monthly schedule at once, creating repetitive administrative work.

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 Dayforce objects map to Bullhorn ATS & CRM

Each row shows how a Dayforce 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.

Dayforce

Worker

maps to

Bullhorn ATS & CRM

Candidate

1:1
Fully supported

Dayforce Worker records map to Bullhorn Candidate. We extract biographical data (legal name, date of birth, address, contact information), employment status, and the Dayforce worker number as the Bullhorn Candidate externalID for dedupe. Dayforce Quick Entry data attached to a Worker migrates as a Candidate note with a timestamp reference. Workers who have been placed or are actively assigned in Dayforce carry an active assignment flag we use to populate the Candidate status and last-placement date in Bullhorn.

Dayforce

Job Assignment

maps to

Bullhorn ATS & CRM

Job Order

1:1
Fully supported

Dayforce Job Assignments associate a Worker to a Job with effective dates, classification codes, and assignment status. We map Job Assignment status (Active, Terminated, On Leave) to Bullhorn Candidate employment status on the Person record. Department, employment type, and work location from Job Assignment transfer to custom fields or the Job Order's corporate information section. Terminated assignments generate a placement history record in Bullhorn with the end date and termination reason preserved.

Dayforce

Job

maps to

Bullhorn ATS & CRM

Job Order

lossy
Fully supported

Dayforce Job records define role-level attributes including job title, FLSA classification, and Workers Comp codes. We create Bullhorn Job Orders as the role-level record, populating title, required skills (from Dayforce job qualifications), and job description. Multiple active Job Assignments under a single Dayforce Job produce multiple Bullhorn Candidate records with the same Job Order reference, representing individual placements under a shared role.

Dayforce

Position Term

maps to

Bullhorn ATS & CRM

Candidate (employment segment)

1:1
Fully supported

Dayforce Position Terms define the duration and status of a position (ongoing, fixed-term, seasonal). We map Position Term status and duration to Bullhorn Candidate custom fields tracking employment type (full-time, part-time, contract) and assignment end date. The ShortName sort key from Dayforce's PositionTerm export becomes a Bullhorn reference number for cross-system audits.

Dayforce

Legal Entity

maps to

Bullhorn ATS & CRM

Corporation (Bullhorn)

1:1
Fully supported

Dayforce Legal Entities define the employing corporate entity per jurisdiction. We map each Dayforce Legal Entity to a Bullhorn Corporation record used as the employer of record for staffing and placement purposes. Corporate address, tax ID, and jurisdiction flags transfer to the Bullhorn Corporation. This mapping is required before any Candidate or Job Order migration because Bullhorn ties employment and placement records to a Corporation.

Dayforce

Pay Rate

maps to

Bullhorn ATS & CRM

Custom Object: Employment Compensation History

lossy
Fully supported

Dayforce Pay Rates are effective-dated on Workers with rate type, amount, and currency. Bullhorn has no native equivalent. We create a custom object Employment_Compensation_History__c on the Candidate record with fields for effective_date, rate_type, hourly_or_salary, amount, currency, and end_date. Effective-dated rates with overlapping start dates are normalized chronologically before import: Dayforce auto end-dates a prior rate when a new one overlaps, and we replicate that logic to preserve a clean rate sequence. We flag any gaps in the rate history that indicate a pay discontinuity.

Dayforce

Earning Grouping

maps to

Bullhorn ATS & CRM

Custom Object: Earning Component Record

lossy
Fully supported

Dayforce Earning Groupings categorize pay components (hours-based, flat, bonus, commission) with MTD/QTD/YTD accumulations. Bullhorn's placement and billing records track commission and contractor pay rates but not HR earning accumulations. We create a custom object Earning_Component__c linked to Candidate, with fields for component_type, hours_or_flat, current_accumulation, and pay_frequency. Accumulation totals migrate as snapshot values at the time of cutover.

Dayforce

Time Off Balance

maps to

Bullhorn ATS & CRM

Custom Object: Time Off Snapshot

lossy
Fully supported

Dayforce Time Off Balances track accrual balances, carryover, and usage per Worker. Bullhorn does not natively manage accrual tracking. We create a custom object Time_Off_Snapshot__c on the Candidate record capturing the accrual type, current balance, accrual rate, carryover amount, and expiration date at migration time. We note that ongoing accrual calculations do not continue post-migration; the customer must configure accrual logic in Bullhorn's custom object or a connected time-tracking tool if ongoing accrual tracking is required.

Dayforce

Benefits Enrollment and Tier

maps to

Bullhorn ATS & CRM

Custom Object: Benefits Enrollment Record

lossy
Fully supported

Dayforce maps benefit plan options to Tiers based on dependent coverage levels with carrier-compatible 063/064 record export. Bullhorn has no native benefits enrollment or administration object. We create a custom object Benefits_Enrollment__c linked to Candidate capturing plan_name, coverage_tier (Employee, Employee+Spouse, Employee+Children, Family), election_status, monthly_premium, and carrier_name. Carrier feed files (063/064 records) do not migrate to Bullhorn and must be reconfigured with the new benefits administrator or carrier directly.

Dayforce

Workers Comp Code

maps to

Bullhorn ATS & CRM

Custom Object: Workers Comp Classification

1:1
Fully supported

Dayforce Workers Comp codes are assigned to Jobs in Org Setup with classification rates and multi-select job-to-code mappings. Bullhorn Job Orders support custom fields for compliance classification. We extract the Workers Comp code-to-job mapping from the Job Assignment export and create a custom object Workers_Comp_Classification__c linked to the Job Order, populating code, classification_description, and rate per code.

Dayforce

Document (Worker-attached)

maps to

Bullhorn ATS & CRM

Document (Candidate-attached)

1:1
Fully supported

Dayforce manages documents attached to Workers (offer letters, contracts, certifications, I-9s). Bullhorn's Document entity attaches files to Candidate records. We extract document metadata (document type, upload date, file name) and binary blobs where accessible via the Dayforce API, and load them as Bullhorn Candidate documents. Document type taxonomy differs between systems: we map Dayforce document types to the closest Bullhorn document category during import. I-9 and tax withholding forms may require re-execution under the new employer and are flagged for the customer's HR admin.

Dayforce

Custom Fields (Worker-level)

maps to

Bullhorn ATS & CRM

Custom Fields (Candidate-level)

lossy
Fully supported

Dayforce supports custom fields at the Worker level with computed-value functions. We extract all custom field values and create matching custom fields on the Bullhorn Candidate object with equivalent data types (text, number, date, picklist). Custom field functions (computed values) do not replicate in Bullhorn; we preserve the last computed value as a static field and document the original function logic for the customer's Bullhorn admin to rebuild as a formula field if supported on the custom field type.

Dayforce

Owner (Worker owner)

maps to

Bullhorn ATS & CRM

User (Bullhorn user)

1:1
Fully supported

Dayforce Workers can have an assigned HR owner or manager. We resolve Dayforce worker owners by email match against Bullhorn User records. Any Dayforce owner without a matching Bullhorn User is held in a reconciliation queue for the customer's Bullhorn admin to provision before record migration resumes. Bullhorn's user-based ownership model differs from Dayforce's HR role assignment, so manager relationships may require a custom field on the Candidate record rather than a native ownership link.

Pair-specific challenges

  • Bullhorn has no native payroll, benefits, or time off tracking

    Bullhorn is an ATS and recruitment CRM. It does not process payroll, manage benefits enrollments, calculate accruals, or interface with insurance carriers. Any Dayforce payroll history, benefits enrollment records, time off accruals, or carrier feeds cannot be migrated as working data in Bullhorn. We create custom objects for compensation history, earning groupings, time off snapshots, and benefits enrollment records to preserve the data as read-only reference history. Active payroll processing, benefits administration, and time and attendance must continue in a dedicated HR or payroll system or be migrated to Bullhorn's separate HR Cloud product. Customers must plan for this gap before migration kickoff.

  • Dayforce undocumented API rate limiter requires conservative throttling

    Dayforce applies rate limiting at the client level on its RESTful API but does not publish specific request thresholds. During bulk migration of large workforces, we may receive 429 responses with no documented retry-after guidance. We implement exponential backoff and conservative request throttling as a precaution. We pre-scope migration batches to estimated safe limits and request the customer's specific rate limit quota from Dayforce support before migration kickoff. Bullhorn's API has a documented limit of 1,000 calls per minute which we also respect during candidate and job order loading.

  • National ID migration supports only TIN and SIN

    Dayforce's Employee National ID migration interface supports only two ID types: Tax Identification Number and Social Insurance Number. Any employee records using other national ID formats such as passport numbers, national registry IDs, work visa numbers, or provincial health card numbers cannot be migrated through the standard Dayforce interface and must be re-entered manually in Bullhorn or handled through an alternative verification workflow. We flag all non-TIN/SIN IDs during pre-migration discovery and deliver a separate spreadsheet of these records for the customer's HR admin to process manually.

  • Bullhorn CSV import requires strict column and ID formatting

    Bullhorn's CSV import for Candidate records enforces specific formatting: required fields vary by import type, field types must match (date formats, numeric precision), and certain fields must be explicitly formatted. An incorrectly formatted file will fail silently or produce mismatched records. We validate all import files against Bullhorn's current import specification before loading and replicate this validation in our extraction pipeline. We also validate Candidate IDs against Bullhorn's deduplication rules before insertion to avoid duplicate record creation.

  • Position Management hierarchy does not map to Bullhorn's flat candidate model

    Dayforce organizes workforces through Position Management hierarchies: Legal Entity > Position > Position Term > Worker. Bullhorn uses a flat candidate model where employment history is a series of records attached to a Candidate rather than a hierarchical chain of employment relationships. We decompose the Position Management hierarchy into discrete records (Corporation, Job Order, Candidate with employment type and status flags) but the structural hierarchy is not preserved in Bullhorn. If the customer requires org chart or position-based headcount reporting, Bullhorn Analytics or a connected BI tool is needed rather than native hierarchy support.

Migration approach

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

  1. Discovery and scope definition

    We audit the Dayforce instance for Worker count, Job Assignment count, Legal Entity count, active pay rate records, earning grouping records, and any custom fields at the Worker level. We map each Dayforce object against Bullhorn's native object model to identify gaps (payroll, benefits, time off accruals, Position Management hierarchy) requiring custom object creation. We review the Bullhorn edition and confirm custom object availability. The discovery output is a written migration scope specifying which objects migrate, which migrate to custom objects, and which are flagged as manual-reentry or excluded. We identify all non-TIN/SIN national IDs and flag them for manual processing.

  2. Schema design and custom object creation

    We design the Bullhorn destination schema before any data extraction begins. This includes creating custom objects (Employment_Compensation_History__c, Earning_Component__c, Time_Off_Snapshot__c, Benefits_Enrollment__c, Workers_Comp_Classification__c) with all required fields, field types, and lookup relationships to the Candidate object. We configure Corporation records for each Dayforce Legal Entity. We design the Bullhorn user mapping: Dayforce worker owners resolved by email match to Bullhorn Users, with missing users placed in a reconciliation queue for the customer's Bullhorn admin to provision.

  3. Sandbox migration and reconciliation

    We run a full migration into a Bullhorn Sandbox using production-equivalent data volume. The customer's Bullhorn admin and HR lead reconcile record counts (Candidates in, Job Orders in, compensation history in, documents in), spot-check 30-50 random records against the Dayforce source, and validate that custom object data is correctly linked to the parent Candidate. Any mapping corrections, field type mismatches, or dedupe key conflicts are resolved in the Sandbox before production migration begins.

  4. Dayforce data extraction with rate-limit handling

    We extract Worker records, Job Assignments, Job records, Position Terms, Legal Entities, Pay Rate history, Earning Grouping records, Time Off balance snapshots, Benefits enrollment records, Workers Comp code mappings, Document metadata and binary blobs, and custom field values from Dayforce via its RESTful API. We apply conservative throttling and exponential backoff throughout to mitigate Dayforce's undocumented rate limiter. CSV-based exports (Job Assignment, Job, PositionTerm) are validated against Dayforce's import formatting requirements before processing. National ID extraction flags any IDs that are not TIN or SIN for the manual-reentry workflow.

  5. Production migration in dependency order

    We run production migration in this order: Bullhorn Users (validated against Dayforce owner emails), Corporations (from Dayforce Legal Entities), custom object schema deployment, Candidate records (with dedupe by externalID), Job Orders (with Corporation lookup resolved), Employment Compensation History (linked to Candidate), Earning Components, Benefits Enrollments, Workers Comp Classifications, Time Off Snapshots, and Documents (binary blobs last due to size). Each phase emits a row-count reconciliation report before the next phase begins. We use Bullhorn's REST API for individual record operations and bulk CSV for high-volume Candidate loads with validation.

  6. Cutover, delta sync, and handoff documentation

    We freeze Dayforce writes during cutover, run a final delta migration of any records modified during the migration window, then enable Bullhorn as the recruiting system of record. We deliver a written inventory of Dayforce workflows, automations, and approval chains that do not migrate to Bullhorn Automation, along with recommended rebuild steps for each. We do not rebuild Dayforce workflows as Bullhorn Automation inside the migration scope. We support a one-week hypercare window where we resolve reconciliation issues raised by the customer's recruiting and HR teams. Benefits carrier feed reconfiguration, payroll system cutover, and I-9 re-execution are the customer's HR team's responsibility post-migration.
