Overview

What this migration involves

Migrating from Workable Zone - HRM to Bullhorn is a move from a combined ATS-and-HRMS platform to a staffing-specialized ATS-and-CRM. Workable candidates, jobs, pipeline stages, scorecards, and offers map 1:1 to Bullhorn's Candidate, JobOrder, Pipeline, Scorecard, and Opportunity records. The structural complication is Workable's HR module: Bullhorn has no native HRIS, so Employee records, Time-Off balances, and payroll data do not migrate into standard Bullhorn objects and are instead inventoried in a written deliverable for the customer to onboard into a separate HRMS. Resume binaries from Workable's bulk export attach to Bullhorn Candidates via the ContentDocument API, which requires a multi-step API call sequence distinct from the standard CSV field mapping. We do not migrate Workflows, Sequences, or Automations; we deliver a written map of every Workable automation for the customer's admin to rebuild in Bullhorn or via a Bullhorn-certified partner.

Why teams make this switch

Two sides of the same decision

Leaving

Workable Zone - HRM

What's pushing teams away

  • Workable removed its Starter plan, effectively doubling the entry-level price, making it harder to justify for small teams on tight budgets.
  • The per-job-posting pricing model creates unpredictable monthly bills as teams scale hiring, especially when comparing to per-employee HRMS alternatives.
  • Limited custom report builder and rigid permission-set structure frustrate power users and HR admins who need deeper configurability.
  • Recurring technical issues and usability friction cited by mid-market and enterprise reviewers on G2 signal reliability concerns at scale.
  • Lack of a native bulk import path means customers building from scratch must engineer their own CSV mapping, pushing some toward platforms with cleaner onboarding.

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 Workable Zone - HRM objects map to Bullhorn ATS & CRM

Each row shows how a Workable Zone - HRM 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.

Workable Zone - HRM

Candidate

maps to

Bullhorn ATS & CRM

Candidate

1:1
Fully supported

Workable Candidate records map to Bullhorn Candidate via the Candidate's email address as the dedupe key. Core fields (firstName, lastName, email, phone, address, LinkedIn URL, source, status) migrate directly. Workable's skills, certifications, and custom text fields map to Bullhorn Candidate standard fields or custom fields if the Bullhorn edition supports them. Resume binaries from Workable's bulk export attach to Bullhorn Candidate via the ContentDocument API: we create the Candidate record first, then issue a POST to /file/{entityType}/{entityId}/uploadDocument to attach the binary with the correct ContentDocumentLink.

Workable Zone - HRM

Employee

maps to

Bullhorn ATS & CRM

Worker (external HRMS required)

lossy
Fully supported

Workable Employee records (skills, payroll details, department, title, employment status) have no native Bullhorn HRIS equivalent. Bullhorn is an ATS-and-CRM for recruitment agencies and does not include an HR module. We exclude Employee records from standard Bullhorn migration scope and instead deliver a written inventory of all Employee fields, data types, and sample values in a CSV for the customer to onboard into a separate HRMS such as BambooHR, Rippling, or ADP. The customer should select and configure the destination HRMS before migration so that any future Employee-to-Candidate conversion can reference the same person record.

Workable Zone - HRM

Job (Job Posting)

maps to

Bullhorn ATS & CRM

JobOrder

1:1
Fully supported

Workable Job postings map to Bullhorn JobOrder. Workable's job status (open, paused, closed) maps to Bullhorn's JobOrder isOpen flag and status field. Workable's departments and offices map to Bullhorn JobOrder categories and businessSector. Workable's pay-rate and employment-type fields map to Bullhorn JobOrder custom fields or standard fields. Active jobs are imported first; archived jobs can be imported in a separate phase or excluded from the primary migration scope.

Workable Zone - HRM

Pipeline Stage

maps to

Bullhorn ATS & CRM

Pipeline (Bullhorn)

lossy
Fully supported

Workable pipeline stages map to Bullhorn Pipeline stages. Each Workable pipeline becomes a Bullhorn Pipeline with its own stage array. Stage names and order transfer directly; stage probabilities map to Bullhorn's probability percentages rounded to the nearest integer. Bullhorn's Pipeline builder is configured during schema setup before any JobOrder records are imported.

Workable Zone - HRM

Scorecard (Evaluation)

maps to

Bullhorn ATS & CRM

Scorecard (Bullhorn)

1:1
Fully supported

Workable interview scorecards and evaluator feedback migrate to Bullhorn Scorecard records linked to the Candidate and JobOrder. Evaluation ratings and free-text reviewer comments transfer as structured fields on the Scorecard. Bullhorn's Scorecard object is entity-specific and attaches to a Candidate submission for a given JobOrder; we ensure the Scorecard is created after both the Candidate and JobOrder exist in Bullhorn by resolving both IDs before inserting.

Workable Zone - HRM

Offer

maps to

Bullhorn ATS & CRM

Opportunity

1:1
Fully supported

Workable Offer records (compensation, start date, offer status, offer letter document) map to Bullhorn Opportunity. The Workable JobOrder ID becomes the parent WhatId on the Opportunity. Compensation fields (salary, bonus, equity) migrate to Bullhorn Opportunity custom fields. The offer letter document migrates as a ContentDocument attached to the Opportunity via ContentDocumentLink. Bullhorn Opportunity stages are configured to reflect the Workable offer lifecycle (offer extended, accepted, declined, rescinded).

Workable Zone - HRM

Time-Off Balance

maps to

Bullhorn ATS & CRM

Custom Object or exclusion (no HRIS)

lossy
Fully supported

Workable Time-Off balances (leave type, balance, accrual rate, used days) have no standard Bullhorn equivalent. Bullhorn does not include a native HRIS or time-tracking module. We exclude Time-Off records from the standard Bullhorn migration scope and deliver them as a structured CSV inventory (employee identifier, leave type, balance, accrual date) with a recommendation to onboard the data into a separate HRMS post-migration. This is a key scoping decision made at the discovery call.

Workable Zone - HRM

Custom Field (Candidate, Employee, Job)

maps to

Bullhorn ATS & CRM

Custom Field or Custom Object (Bullhorn)

1:1
Fully supported

Workable custom properties (text, number, date, dropdown, boolean, multi-select) on Candidates, Employees, and Jobs map to Bullhorn Candidate, JobOrder, or Worker custom fields. Bullhorn Enterprise and Front Office Growth support up to 10 custom objects with 55 fields each; Bullhorn ATS Growth supports 2 custom objects; Bullhorn ATS does not support custom objects. We pre-create the destination custom fields via Bullhorn metadata API before import. Workable custom fields that exceed Bullhorn's field count limits per entity are flagged in scoping and mapped to a custom object or excluded with a written explanation in the migration inventory.

Workable Zone - HRM

Company (Workable HR module)

maps to

Bullhorn ATS & CRM

ClientCorporation

1:1
Fully supported

Workable Companies stored in the HR module (the employer side of the organization) map to Bullhorn ClientCorporation if the migration scope includes company records. Workable's company name, website, industry, and address map to Bullhorn ClientCorporation standard fields. For staffing firms, Workable's client companies map to ClientCorporation; for in-house recruiting teams moving to Bullhorn, the Workable HR module company record may represent the employer organization itself and is treated as a ClientCorporation in Bullhorn for consistency.

Workable Zone - HRM

Note (Candidate, Employee, Job)

maps to

Bullhorn ATS & CRM

Note

1:1
Fully supported

Workable notes attached to Candidates, Employees, or Jobs migrate to Bullhorn Note records linked via ContentDocumentLink to the parent record. Rich-text notes transfer as Note Body; the original author and timestamp are preserved. Bullhorn Note is subject to the 55-field limit on the parent entity but Note itself is a standard object and does not consume custom object allocation.

Workable Zone - HRM

Attachment (Resume, Offer Letter, Employee Document)

maps to

Bullhorn ATS & CRM

ContentDocument

1:1
Fully supported

Binary attachments from Workable's bulk export (resumes in PDF/DOCX, offer letters, employee documents) migrate as Bullhorn ContentDocument records attached to the parent Candidate, Opportunity (for offers), or Worker record via ContentDocumentLink. Resume files for Candidates use the dedicated /file/{entityType}/{entityId}/uploadDocument endpoint after Candidate creation. We verify each ContentDocument is linked before proceeding to the next batch. Files exceeding Bullhorn's size limits (typically 25 MB per file) are flagged and optionally split or excluded.

Workable Zone - HRM

Owner (Workable user)

maps to

Bullhorn ATS & CRM

User (Bullhorn)

1:1
Fully supported

Workable Owners referenced on Candidate, Job, and Offer records are resolved to Bullhorn User records by email match. Bullhorn requires every record to have a valid OwnerId at insert time. Any Workable Owner whose email does not exist in the Bullhorn destination org is held in a reconciliation queue; the customer's Bullhorn admin provisions the missing User before we resume migration. We do not create Bullhorn Users on behalf of the customer.

Workable Zone - HRM

Candidate Source

maps to

Bullhorn ATS & CRM

Candidate Source

1:1
Fully supported

Workable's candidate source field (job board, referral, LinkedIn, direct application) maps directly to Bullhorn Candidate.source. Source values are preserved as-is; if the customer wants to normalize source values post-migration, we flag this as a post-migration admin task in the handoff document.

Workable Zone - HRM

Interview Schedule

maps to

Bullhorn ATS & CRM

Event (Calendar Entry)

1:1
Fully supported

Workable self-scheduled interview bookings (candidate name, interview type, scheduled time, interviewer, meeting link) map to Bullhorn Event records linked to the Candidate and JobOrder. StartDateTime, EndDateTime, and Location transfer directly. Bullhorn EventRel records are created for each interviewer listed in the Workable interview schedule to preserve the attendee list.

Pair-specific challenges

  • Bullhorn has no native HRIS module

    Workable Zone - HRM includes employee records, Time-Off balances, payroll data, and performance information in its HR module. Bullhorn is an ATS-and-CRM built for staffing agencies and does not include a native HRMS. Employee records, Time-Off data, and HR documents cannot migrate into standard Bullhorn objects. We exclude this data from the Bullhorn migration scope and deliver it as a structured CSV inventory for the customer to onboard into a separate HRMS (BambooHR, Rippling, ADP, or similar) post-migration. This is a fundamental architectural gap, not a field-mapping issue, and must be addressed before or during migration scoping.

  • Resume binaries require a separate API call sequence

    Workable's bulk API export delivers candidate field data and resume binaries as separate payloads. Bullhorn requires resume files to be attached after the Candidate record is created, using the /file/Candidate/{candidateId}/uploadDocument REST endpoint. This is a two-step process: create the Candidate first, then attach the ContentDocument with the correct ContentDocumentLink. Bullhorn's CSV import path does not handle binary attachments. Teams that rely on the UI-based CSV export (which excludes resumes) will see an empty document column in their export and must use the bulk API. We handle this API sequence explicitly in the migration pipeline.

  • Bullhorn field and custom object limits vary by edition

    Bullhorn ATS Growth is limited to 2 custom objects; Bullhorn ATS has no custom objects; Enterprise and Front Office Growth support up to 10 custom objects with 55 fields each. Workable custom fields on Candidates, Employees, and Jobs that exceed Bullhorn's per-entity field limit must be redistributed to a custom object or excluded. We audit custom field count and type during scoping. If the customer is on Bullhorn ATS Growth and has more than 2 custom objects worth of Workable fields, we recommend upgrading to Enterprise or mapping the highest-priority fields only, with the rest inventoried as excluded.

  • Bullhorn requires an owner on every record

    Bullhorn enforces a required OwnerId on all standard entities at insert time. Workable owners (recruiters, hiring managers) referenced in the source data must resolve to a Bullhorn User by email match before record import. If a Workable Owner has no corresponding Bullhorn User account, their records are held in a reconciliation queue. Bullhorn does not allow bulk import of records without a valid owner; proceeding without resolving this first produces orphaned records and import failures. We surface the reconciliation queue after the owner scan and do not begin record import until the queue is resolved.

  • Custom Component Fields are not supported for data migration

    Bullhorn's Custom Component Fields are reserved for integrations and automations and are not intended for general data migration use. Bullhorn's own knowledge base explicitly warns against using Custom Component Fields for general record data, as they can cause reporting issues and compatibility problems with future Bullhorn updates. Workable custom fields that are technically compatible with Custom Component Fields are instead mapped to Bullhorn Custom Objects or standard fields by FlitStack AI. This avoids a migration path that would create long-term maintenance problems in Bullhorn.

Migration approach

Six steps for a successful Workable Zone - HRM to Bullhorn ATS & CRM data migration

  1. Discovery and scoping call

    We audit the Workable Zone - HRM account across active job count, total candidate records, employee record count, custom field inventory, attachment volume (resumes, offer letters, employee documents), pipeline stage count, and active workflows or automations. We pair this with a Bullhorn edition assessment to determine whether the customer's target Bullhorn tier supports the required custom object count. We explicitly flag the HRIS gap during this call: Employee records, Time-Off balances, and HR documents do not migrate into Bullhorn and require a separate HRMS onboarding plan. The discovery output is a written migration scope with record counts, HR data disposition, and Bullhorn edition recommendation.

  2. Schema setup in Bullhorn

    We configure Bullhorn before any data moves. This includes creating Bullhorn Pipeline records that mirror Workable's pipeline stage names and probabilities, configuring JobOrder status field values (open, paused, closed) to match Workable's job lifecycle, provisioning custom fields via Bullhorn metadata API to match Workable's custom property types, and requesting Bullhorn Support to create any required custom objects (up to 10 on Enterprise). Bullhorn field mapping enforces a 55-field limit per entity; custom fields exceeding this threshold are redistributed to custom objects or flagged as excluded. Bullhorn edition limits are checked against the Workable custom field inventory before schema creation begins.

  3. Workable bulk export and data extraction

    We extract data from Workable using the bulk API export endpoint for Candidates, including resume binaries as separate file payloads. We pull Jobs, Pipeline stages, Scorecards, Offers, Notes, and custom field values in parallel. For the HR module, we extract Employee records and Time-Off balances separately for the HR data inventory deliverable. We validate record counts against the Workable UI and flag any discrepancy before transformation begins. Owner email addresses are extracted from all entities for the Bullhorn User reconciliation step.

  4. Sandbox migration and reconciliation

    We run a full migration into the customer's Bullhorn Sandbox (Partial Copy or Full Copy depending on data volume) before touching production. The customer's Bullhorn admin reviews record counts (Candidates in, JobOrders in, Pipeline stages configured, Scorecards attached, Opportunities created), spot-checks 25-50 candidate records for field accuracy, verifies resume attachment presence, and reviews the Owner reconciliation queue. Any mapping corrections, custom field additions, or Bullhorn User provisioning requirements surface here and are resolved before production migration begins.

  5. Owner reconciliation and User provisioning

    We extract every distinct Workable Owner referenced across all migrating entities and match by email against the Bullhorn destination org's User table. Workable Owners with no matching Bullhorn User go to a written reconciliation queue. The customer's Bullhorn admin provisions any missing Users (active or inactive depending on whether the original Workable user is still with the firm). Migration cannot proceed past the User validation gate because Bullhorn rejects any record insert without a valid OwnerId. We resume migration only after the reconciliation queue is confirmed empty.

  6. Production migration in dependency order

    We run production migration in record-dependency order: Users (validated from step 5), ClientCorporations (for staffing firms with client records), Candidates with resume binaries (Candidate created first via REST, then ContentDocument attached via /file/Candidate/{id}/uploadDocument, then ContentDocumentLink created), JobOrders (with status flags from Workable job status), Pipelines (stage values matched to Bullhorn Pipeline), Scorecards (linked to Candidate and JobOrder by resolved IDs), Opportunities (for offers, with JobOrder as WhatId), Notes (via ContentDocumentLink), and HR data inventory (Employee CSV, Time-Off CSV delivered separately for the customer's HRMS onboarding). Each phase emits a row-count reconciliation report before the next phase begins.

  7. Cutover, validation, and handoff

    We freeze writes on Workable during the cutover window, run a final delta migration of any records modified during the migration window, then deliver the production reconciliation report. We validate record counts, spot-check resume attachments, verify Opportunity records against Workable Offer data, and confirm Notes are linked to the correct parent records. We deliver the written Workflow and Automation inventory (all Workable automations documented with trigger, conditions, and actions for Bullhorn rebuild) and the HR data inventory CSV. We support a one-week hypercare window for reconciliation issues raised by the recruiting team. Workflow rebuild in Bullhorn is a separate engagement handled by the customer's admin or a Bullhorn-certified implementation partner.
