Overview

What this migration involves

Moving from ZingHR to Bullhorn is a cross-domain migration: ZingHR is a Hire-to-ReHire HCM platform covering onboarding, payroll, attendance, leave, and performance, while Bullhorn is a staffing-focused ATS and CRM built for candidate sourcing, job management, and placement tracking. The structural difference is significant — ZingHR tracks the employee lifecycle; Bullhorn tracks the recruitment cycle. We resolve this by mapping ZingHR employee records to Bullhorn Candidates, ZingHR departments to Bullhorn Corporate structure, leave balances and payroll history to Bullhorn custom objects (where your edition permits), and attendance summaries to Candidate notes or custom fields. ZingHR's Maker-Checker approval workflows, performance review goals, and custom attributes from the Attribute Master API all require explicit mapping or rebuild planning. Bullhorn workflows, automations, and Bullhorn Automation (formerly Herefish) sequences do not migrate; we deliver a written inventory for your admin to rebuild post-cutover.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Why teams make this switch

Two sides of the same decision

Leaving

ZingHR logo

ZingHR

What's pushing teams away

  • Frequent performance issues including slow page loads, login timeouts, and sluggish navigation frustrate daily users and reduce productivity across HR and employee self-service.
  • Integration challenges with third-party tools create data silos, particularly when ZingHR must sync with existing ERP or finance systems that enterprises already rely on.
  • Customer support response times are reported as slow, with users noting difficulty getting timely assistance when configuration issues arise.
  • Setup complexity requires significant configuration effort to align the platform with company-specific structures, policies, and approval hierarchies.

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 ZingHR objects map to Bullhorn ATS & CRM

Each row shows how a ZingHR 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.

ZingHR

Employee

maps to

Bullhorn ATS & CRM

Candidate

1:1
Fully supported

ZingHR employee records map to Bullhorn Candidate as the primary person record. We extract personal details (name, DOB, address, contact), employment details (department, designation, date of joining, employment type), and employment history. The Bullhorn Candidate record serves as the parent for placement, attendance notes, and payroll custom fields. We map ZingHR employee status (active, on leave, separated) to Bullhorn Candidate status, and flag any ZingHR e-Separation records as inactive Candidate records with separation date preserved.

ZingHR

Department

maps to

Bullhorn ATS & CRM

Corporate (Departments)

1:1
Fully supported

ZingHR department hierarchies map to Bullhorn Corporate records representing the customer's own organizational structure. We extract cost-center assignments and org chart reporting lines from ZingHR's organization report. Bullhorn Corporate records hold company-level details; individual department-level granularity beyond the top-level company name requires a custom field or a custom object (e.g., Internal_Department__c) if Bullhorn's standard Corporate fields are insufficient.

ZingHR

Location

maps to

Bullhorn ATS & CRM

Corporate Address or JobOrder Location

1:1
Fully supported

ZingHR location records include geo-coordinates, address details, and location-specific configurations. We extract location names and structured address data from ZingHR's reports. Bullhorn stores addresses on Corporate records and on JobOrder records. For multi-location ZingHR customers, we map each ZingHR location to a Bullhorn Corporate address entry. Geo-coordinates are stored as custom fields on the Corporate record if Bullhorn's standard address block does not capture them.

ZingHR

Attendance Records

maps to

Bullhorn ATS & CRM

Note (on Candidate)

1:1
Mapping required

ZingHR attendance punch-in and punch-out data in raw timestamp format is aggregated into daily attendance summaries to avoid inflating Bullhorn record counts. Aggregated summaries are stored as Note records linked to the Candidate, with the note body containing attendance statistics (days present, days absent, late arrivals, overtime hours) and the note date set to the period end date. Raw timestamp records are not individually migrated to Bullhorn because Bullhorn does not have a native attendance or time-tracking object.

ZingHR

Leave Balances

maps to

Bullhorn ATS & CRM

Custom Object (Leave_Balance__c)

1:1
Fully supported

ZingHR leave types (earned leave, sick leave, casual leave, compensatory off) and their entitlement, accrual, used, and balance values map to a Bullhorn Custom Object (Leave_Balance__c) linked to the Candidate. Bullhorn Support must create this custom object because it is not self-service. The number of leave types drives the number of custom object instances per employee. We verify compensatory off balances in ZingHR before cut-off since some users report these do not auto-refresh correctly.

ZingHR

Payroll History

maps to

Bullhorn ATS & CRM

Custom Object (Payroll_History__c)

1:1
Mapping required

ZingHR payslip data including earnings, deductions, and net pay per pay period maps to a Bullhorn Custom Object (Payroll_History__c) linked to the Candidate or Placement. We sequence records by pay date and handle month-end cutoffs carefully. Bullhorn does not have a native payroll object; pay rate and bill rate are stored as fields on the Placement record, but full payroll history requires the custom object. Custom Object availability is limited by Bullhorn edition: Front Office Growth/Enterprise allows 10, ATS allows 2, and ATS Growth allows 0, which constrains how many payroll periods or additional HR data types can be stored.

ZingHR

Performance Reviews

maps to

Bullhorn ATS & CRM

Custom Object (Performance_Review__c)

1:1
Mapping required

ZingHR PMS module goal progress, ratings, and reviewer comments map to a Bullhorn Custom Object (Performance_Review__c) linked to the Candidate. We extract goal titles, alignment to business outcomes, rating values, and reviewer metadata. Bullhorn has no native performance management module; performance history is not surfaced in standard Bullhorn reporting, so the custom object provides a historical record accessible via Bullhorn search and list views. The customer's Bullhorn edition limits how many additional custom objects can be created alongside leave balance and payroll history.

ZingHR

Documents

maps to

Bullhorn ATS & CRM

ContentDocument (via Note or Attachment)

1:1
Mapping required

ZingHR employee documents (offer letters, ID proofs, experience letters) are downloaded individually from the ESS portal and mapped to Bullhorn ContentDocument records attached via ContentDocumentLink to the Candidate. We map ZingHR document categories to Bullhorn document type values and flag any documents that exceed Bullhorn's supported attachment size limits. Documents are imported after the Candidate record is created to satisfy the parent-lookup requirement.

ZingHR

Manager Hierarchy

maps to

Bullhorn ATS & CRM

Candidate (recruiter, supervisor fields)

1:1
Fully supported

ZingHR manager-employee associations are extracted as reporting lines and replicated in Bullhorn by populating the recruiter and supervisor fields on the Candidate record. For Bullhorn's staffing context, the manager relationship maps to the assigned recruiter on a candidate's record and the hiring manager field on related job orders. Bulk manager-change records in ZingHR that are in a pending Maker-Checker approval state are flagged during scoping and excluded from migration until the approval is completed or the admin resolves them in ZingHR before cut-over.

ZingHR

Recruitment Data (Job Postings)

maps to

Bullhorn ATS & CRM

JobOrder

1:1
Fully supported

ZingHR Talent Acquisition job postings and active candidate pipelines map to Bullhorn JobOrder records. Each ZingHR job requisition becomes a JobOrder with status, title, description, and requirements fields populated. ZingHR candidate profiles in the recruitment pipeline map to Bullhorn JobApplication records linked to the JobOrder and Candidate. Onboarding checklists from ZingHR do not migrate as workflow items; they are documented in the handoff inventory for the customer's Bullhorn admin to recreate using Bullhorn Automation or Bullhorn Onboarding.

ZingHR

Custom Fields (Attribute Master API)

maps to

Bullhorn ATS & CRM

Custom Fields or Custom Object fields

lossy
Fully supported

ZingHR Attribute Master API exposes company-specific custom fields and units that may not map to any standard Bullhorn field. We enumerate all ZingHR custom attributes during scoping, classify them as either inline custom fields on the Candidate (if Bullhorn's available custom field slots are sufficient) or as fields within a custom object, and coordinate with Bullhorn Support for custom object setup. Picklist and formula-type custom fields in ZingHR require explicit mapping to Bullhorn picklist values or formula fields respectively.

ZingHR

ZingHR User / Owner

maps to

Bullhorn ATS & CRM

Bullhorn User

1:1
Fully supported

ZingHR users who are active in the system map to Bullhorn User records. We extract users by email match to the Bullhorn destination environment. Any ZingHR user without a matching Bullhorn User goes to a reconciliation queue for the customer's Bullhorn admin to provision before record import resumes, because OwnerId references on Bullhorn records are required and cannot be null for most standard objects.

Pair-specific challenges

  • ZingHR Maker-Checker bulk records block migration

    ZingHR uses a Maker-Checker (dual-approval) workflow for bulk operations including manager changes. Records in a pending-approval state in ZingHR do not auto-commit to Bullhorn. We identify all pending Maker-Checker records during scoping and flag them so they can be completed in ZingHR before migration or recreated as Bullhorn tasks for the admin post-migration. Any manager hierarchy change that is pending approval at cut-over will not reflect the new manager in Bullhorn unless the approval is resolved in ZingHR first.

  • Bullhorn custom object tier limits constrain HCM data storage

    Bullhorn's custom object allocation is edition-gated: Front Office Growth and Enterprise allow up to 10 custom objects with 55 fields each, Bullhorn ATS allows 2, and ATS Growth allows 0. A full ZingHR HCM migration requiring leave balances, payroll history, performance reviews, and custom attributes may exceed 2 custom objects. We scope the custom object requirement during discovery, recommend the appropriate Bullhorn edition upgrade if needed, and coordinate with Bullhorn Support to pre-create custom objects before migration data flows in. Custom objects created as part of marketplace integrations or compliance functionality do not count toward the limit.

  • Bullhorn workflows and Bullhorn Automation do not migrate

    Bullhorn does not import ZingHR workflow configurations, approval chains, or Bullhorn Automation (formerly Herefish) sequences as portable artefacts. We do not migrate them as code. We deliver a written inventory of every active ZingHR workflow and approval hierarchy with its trigger, conditions, actions, and a recommended Bullhorn equivalent, and the customer's Bullhorn admin or a Bullhorn partner rebuilds them. Bullhorn Automation requires a separate license and configuration; it is not included in standard Bullhorn ATS tiers.

  • ZingHR API token rotation can interrupt extraction mid-migration

    ZingHR's Attribute Master API uses token plus SubscriptionName for authentication, where tokens are account-scoped and may expire or rotate. We request fresh API credentials during migration kickoff and implement token-refresh handling in our extraction pipeline. If a token rotates during a large migration run, we detect the auth failure, request a fresh token, and resume from the last confirmed checkpoint rather than re-exporting the entire dataset.

  • ZingHR historic data export capped at 60 months

    ZingHR's Reports module separates current data (last 3 months) from historic data (up to 5 years). The 60-month cap means attendance, leave, and payroll records older than five years are not available for export. We always use the Historic data export for full-scope migrations to avoid silently truncating records at the quarter boundary. Customers with compliance requirements for records beyond 60 months must retain those records in ZingHR or export them manually before the migration cut-over date.

Migration approach

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

  1. Discovery and scope definition

    We audit the source ZingHR instance across modules in scope (HCM, payroll, attendance, leave, performance, recruitment), employee population, custom fields exposed via the Attribute Master API, active Maker-Checker workflows, and the number of leave types and payroll periods to migrate. We pair this with a Bullhorn edition assessment to determine whether Front Office Growth or Enterprise is needed to accommodate the required custom objects (leave balances, payroll history, performance reviews). The discovery output is a written migration scope document covering record counts, object-to-object mapping, and the Bullhorn edition recommendation.

  2. Schema design and custom object coordination

    We design the Bullhorn destination schema including custom fields on Candidate and JobOrder for manager relationships and location data, custom objects (Leave_Balance__c, Payroll_History__c, Performance_Review__c) with all required fields and field types, Bullhorn Field Mappings configuration for dropdown values and edit types, and Bullhorn Support coordination to pre-create custom objects before any data import. We resolve the manager hierarchy mapping by identifying which Bullhorn User each ZingHR manager maps to by email.

  3. Sandbox migration and reconciliation

    We run a full migration into a Bullhorn Sandbox environment using a representative data volume sample. The customer's staffing operations lead reconciles record counts (Candidates in, Leads in, JobOrders in, Placements in, custom object instances in), spot-checks 25-50 records against ZingHR source data, and validates that leave balances and payroll history are correctly sequenced by period. Any mapping corrections and field type adjustments happen in the Sandbox before production migration begins.

  4. User provisioning and owner reconciliation

    We extract every distinct ZingHR user referenced on employee records, manager assignments, and recruitment data and match by email against the Bullhorn destination's User table. Users without a matching Bullhorn User go to a reconciliation queue. The customer's Bullhorn admin provisions any missing Users before record import resumes, because Bullhorn OwnerId references on Candidate, JobOrder, and Placement records are required and cannot be null during data load.

  5. Production migration in dependency order

    We run production migration in dependency order: Bullhorn Users validated, then Candidate records (from ZingHR Employees), Corporate records (from ZingHR Departments), JobOrder records (from ZingHR job postings), Leave_Balance__c custom object instances (per Candidate per leave type), Payroll_History__c custom object instances (per Candidate per pay period), Performance_Review__c custom object instances (per Candidate per review cycle), documents (as ContentDocument records linked to Candidate), attendance summary notes (linked to Candidate), and manager hierarchy resolved via recruiter and supervisor fields. Each phase emits a row-count reconciliation report before the next phase begins.

  6. Cutover, validation, and workflow handoff

    We freeze writes in ZingHR 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 ZingHR workflow and automation inventory document to the customer's Bullhorn admin team with recommended Bullhorn Automation equivalents. We support a one-week hypercare window where we resolve any reconciliation issues. We do not rebuild ZingHR workflows as Bullhorn Automation inside the migration scope; that is a separate engagement or an internal admin task.

Most migrations land between four and six weeks for organizations under 500 employees with attendance, leave, and basic employee data in scope and no more than two custom objects required in Bullhorn. Migrations with full payroll history spanning multiple years, performance review goals, populations over 2,000 employees, or organizations needing Bullhorn edition upgrades to accommodate the required custom objects move to ten to fourteen weeks because of custom object setup coordination with Bullhorn Support, payroll period sequencing, and extended validation cycles.
