Overview
Cavu HCM and Bullhorn serve different primary functions: Cavu HCM is a payroll-first HRMS built for U.S. small and mid-sized businesses, while Bullhorn is a recruiting-focused ATS and CRM built for staffing and recruitment agencies. The migration is meaningful for staffing firms that used Cavu HCM for internal workforce management and need to consolidate candidate, client, job order, and placement data into Bullhorn, or for temp staffing agencies that need Cavu's payroll engine alongside Bullhorn's recruiting front office. Because Cavu HCM exposes no public API, we extract data through the Employer on Demand portal in sequential sessions, assemble each employee record from multiple portal exports (employer, employee, time supervisor, and HR self-service portals), and then map that assembled record to Bullhorn's Candidate, Client Corporation, Job Order, and Placement objects. Payroll earnings, deductions, and garnishment data do not have a native Bullhorn equivalent; we convert these into Bullhorn Placement pay rates and bill rates, and we deliver a separate payroll reconciliation file for the customer's finance team. Workflows, automations, and scheduled sequences do not migrate as code; we deliver a written inventory for the Bullhorn admin to rebuild in Bullhorn Workflow or Bullhorn Automation Engine.

Object mapping
Each row shows how a Cavu HCM 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.
Cavu HCM
Employee (active workforce)
Bullhorn ATS & CRM
Candidate
1:1Cavu HCM employee records map to Bullhorn Candidate. We extract name, address, contact details, department, job title, hire date, and compensation from the Employer on Demand portal export. For temp staffing firms, current employees who are placed with clients become active Candidate records; internal support staff become Candidates with a do-not-place flag or are excluded per the customer's scoping decision. The Cavu employee status (active, terminated, on leave) maps to a Bullhorn custom Candidate status field because Bullhorn's standard status is recruiting-stage-driven rather than employment-status-driven.
Cavu HCM
Employee (employment history)
Bullhorn ATS & CRM
Candidate Employment
1:1Cavu HCM stores current job assignment and prior employment within the employee record. We extract each distinct job title, employer name, start and end date, and description and load these as Bullhorn Candidate Employment history records. Bullhorn supports multiple employment entries per Candidate with job title, company name, dates, and description fields. We sequence entries chronologically with the most recent role first.
Cavu HCM
Applicant Profile
Bullhorn ATS & CRM
Candidate
1:1Cavu HCM's talent management module stores applicant data including application status, screening results, and onboarding task completion. We migrate the most recent application per candidate as a Bullhorn Candidate record, preserving the Cavu application pipeline stage in a custom Candidate field candidate_origin_pipeline__c for reconciliation. The candidate's resume document migrates as a Bullhorn CV/Resume attached to the Candidate record via ContentDocumentLink.
Cavu HCM
Company
Bullhorn ATS & CRM
Client Corporation
1:1Cavu HCM company records map to Bullhorn Client Corporation. The Cavu company name, address, and industry code map to the corresponding Bullhorn Client Corporation fields. Client Corporation is created before any Candidate import so that the client-facing relationship (Candidate submitted to a Client Corporation's Job Order) is established during migration. We use the Cavu company name as the dedupe key during Bullhorn import.
Cavu HCM
Job Requisition
Bullhorn ATS & CRM
Job Order
1:1If Cavu HCM stores internal job requisitions or published job openings, these map to Bullhorn Job Order. Each Job Order in Bullhorn links to a Client Corporation, a Contact at that client, and one or more Job Shifts (full-time, part-time, contract). The Cavu job title and description map to Job Order title and description; salary range maps to pay range. Open, filled, and closed status maps to the corresponding Bullhorn Job Order status values.
Cavu HCM
Scheduled Shift
Bullhorn ATS & CRM
Placement
1:manyCavu HCM scheduled shifts with employee assignment, start/end time, and client location map to Bullhorn Placement records for temp staffing firms. Each Cavu shift with a client assignment becomes a separate Placement with the Cavu employee as the Candidate, the Cavu company as the Client Corporation, and the shift start/end date as the Placement start/end date. Recurring schedule templates are extracted separately and reconstituted as recurring Placements or Shift Pattern records in Bullhorn.
Cavu HCM
Payroll: Earnings
Bullhorn ATS & CRM
Placement (pay rate and bill rate)
lossyCavu HCM payroll earnings records do not have a native Bullhorn equivalent because Bullhorn is not a payroll engine. We convert Cavu earnings into Bullhorn Placement pay rate and bill rate fields. For temp staffing placements, the Cavu employee's base hourly or salary rate becomes the Bullhorn Placement payRate; the Cavu client's billing rate becomes the Bullhorn Placement billRate; and the markup (billRate minus payRate) is preserved for margin reporting. We deliver a separate payroll reconciliation CSV of all extracted earnings, deductions, and taxes for the customer's finance team to import into their payroll system of record.
Cavu HCM
Payroll: Tax Withholding
Bullhorn ATS & CRM
Payroll Reconciliation File (no Bullhorn object)
lossyCavu HCM federal, state, and local tax withholding setups, including multi-state LDG jurisdiction assignments, are extracted as a separate tax configuration export. These do not load into Bullhorn because Bullhorn does not store tax withholding configurations. We deliver the tax configuration as a structured CSV with jurisdiction codes, withholding rates, and effective dates for the customer's payroll administrator to configure in their new payroll system (whether that is a Bullhorn-integrated payroll partner or a standalone payroll platform).
Cavu HCM
Payroll: Garnishments and Deductions
Bullhorn ATS & CRM
Placement Custom Fields or Payroll Reconciliation File
lossyCavu HCM garnishment orders, voluntary deductions, and benefit withholdings attach to the employee record. We extract these as structured data and load them into Bullhorn Placement custom fields (if the customer licenses Bullhorn Front Office or Growth and requests garnishment tracking on Placement) or deliver them as a structured CSV alongside the payroll reconciliation file. Bullhorn does not natively process payroll deductions; these are handled by the customer's payroll system.
Cavu HCM
Benefits Enrollments
Bullhorn ATS & CRM
Candidate Custom Fields or Candidate Note
lossyCavu HCM benefit elections (health, dental, vision, 401k) with effective dates are extracted per employee. Bullhorn does not have a native benefits enrollment object because it is a recruiting ATS, not an HRMS. We load active benefit enrollment status as Bullhorn Candidate custom fields (e.g., benefits_enrolled__c, benefits_plan_tier__c) or as a Candidate Note for administrative reference. We sequence enrollments chronologically and flag any mid-year enrollment changes as separate Candidate Note entries with effective dates.
Cavu HCM
PTO Balances
Bullhorn ATS & CRM
Candidate Custom Fields or Payroll Reconciliation File
lossyCavu HCM PTO accrual balances and usage history per employee are extracted as structured data. Bullhorn does not have a PTO accrual object. We convert current PTO balance, accrual rate, and usage history into Candidate custom fields (pto_balance_hours__c, pto_accrual_rate__c) or deliver them in the payroll reconciliation file for the customer's new payroll system to consume. Leave type distinctions (vacation, sick, personal) map to separate custom fields per leave type.
Cavu HCM
Documents
Bullhorn ATS & CRM
ContentDocument (attached to Candidate or Client Corporation)
1:1Cavu HCM employee documents (new hire forms, tax withholdings, I-9s, performance reviews) export from the Document Storage module as individual files with folder metadata. We load each document as a Bullhorn ContentDocument record and attach it via ContentDocumentLink to the corresponding Candidate or Client Corporation record. We preserve the original Cavu folder structure as Bullhorn ContentWorkspace records (libraries) so that I-9s, tax forms, and performance reviews remain organized. File content migrates as-is; we do not convert file formats.
Cavu HCM
Time Entries
Bullhorn ATS & CRM
Placement Timecards or Candidate Custom Fields
lossyCavu HCM time and attendance records (clock-in/clock-out events) export per employee. For temp staffing placements, we convert Cavu time entries into Bullhorn Placement Timecard entries (start time, end time, break, total hours) linked to the corresponding Placement record. Entries that were edited or approved post-submission are flagged with a custom field timecard_edited__c for the customer's timekeeping administrator to review. For non-placement employees, time entries are delivered as a structured CSV for payroll reconciliation.
Cavu HCM
Custom Objects (Cavu)
Bullhorn ATS & CRM
Bullhorn Custom Object
1:1If Cavu HCM contains custom employee data structures (compliance tracking, certification management, certification expiration schedules), these map to Bullhorn Custom Objects. Bullhorn's API supports custom objects with up to 55 fields per object depending on tier: Front Office Growth and Enterprise allow 10 custom objects; Bullhorn ATS allows 2; ATS Growth allows none. We pre-create the destination Bullhorn custom object schema during the sandbox phase, including all custom fields, picklist values, and lookup relationships, before any data import. Custom object naming follows Bullhorn's __c API name convention.
Cavu HCM
Pay Schedules
Bullhorn ATS & CRM
Payroll Reconciliation Configuration
lossyCavu HCM pay schedule configuration (weekly, bi-weekly, semi-monthly, monthly) and associated GL mapping export cleanly. Bullhorn does not have a pay schedule configuration object. We deliver pay schedule configuration as a structured reference file with frequency, GL account mappings, and effective dates for the customer's payroll administrator to configure in their new payroll system. Pay schedule frequency also informs the payroll reconciliation CSV column structure.
Cavu HCM
Owner (Cavu payroll guide or HR admin)
Bullhorn ATS & CRM
Bullhorn User
1:1Cavu HCM's dedicated payroll guide model assigns a named payroll contact per client. We extract all Cavu owner and administrator records and match them by email against Bullhorn User accounts. Any Cavu owner without a matching Bullhorn User is held in a reconciliation queue for the customer's Bullhorn admin to provision before record import resumes. Active/inactive status maps to the Bullhorn User isActive flag.

Migration approach
Discovery and portal access verification
We audit the Cavu HCM portal across all four login URLs (employer, employee, time supervisor, HR self-service) to identify which data modules are in active use. We extract a full employee census including name, address, department, job title, hire date, and compensation. We verify that the customer has active portal credentials and that the IRIS Global rebrand has not invalidated their access. We also confirm the Bullhorn edition the customer has licensed (Bullhorn ATS, ATS Growth, Front Office Growth, or Enterprise) so that custom object limits are known before schema design begins. The discovery output is a written migration scope, portal access confirmation, and Bullhorn edition note.
Sequential portal export and cross-portal reconciliation
Because Cavu HCM has no API, we perform sequential exports from each portal in separate authenticated sessions. We chunk the export into batches to avoid session timeouts, stitch the batches, and then cross-reconcile across portals to produce a complete employee record. Any records that appear only in one portal (for example, a time entry in the supervisor portal with no corresponding employee record in the HR portal) are flagged and escalated to the customer's HR administrator for resolution before data transformation begins. The reconciliation output is a clean, de-duplicated employee dataset with all associated payroll, benefit, PTO, time entry, and document records linked.
Schema design and payroll-to-placement conversion logic
We design the Bullhorn destination schema based on the reconciled Cavu export. For temp staffing firms, we design the Candidate-to-Placement pipeline: Cavu employees become Bullhorn Candidates; Cavu scheduled shifts with client assignments become Bullhorn Placements with pay rate (Cavu employee earnings) and bill rate (Cavu client billing rate). For direct-hire staffing firms, Cavu employees become Bullhorn Candidates without Placement records, and the Cavu job requisition becomes a Bullhorn Job Order. We pre-create Bullhorn custom objects (within the licensed tier's limit), custom fields, and any required picklists before migration. Schema is validated in a Bullhorn Sandbox before production migration begins.
Bullhorn Sandbox migration and reconciliation
We run a full migration into a Bullhorn Sandbox using the production-equivalent record volume. The customer's Bullhorn administrator and HR lead reconcile record counts (Candidates in, Client Corporations in, Job Orders in, Placements in), spot-check 25-50 records against the Cavu source data, and validate that pay rates, bill rates, and employment history are correctly mapped. Any schema corrections, field mapping errors, or missing custom object provisioning are resolved in the Sandbox before production migration begins. Bullhorn's import tools accept CSV and API-based formats; we confirm the preferred format with the customer's Bullhorn admin during this phase.
Production migration in record dependency order
We run production migration in record dependency order: Bullhorn Users (validated against the Cavu owner/reconciled list), Client Corporations (from Cavu company records), Candidates (with employment history and document attachments), Job Orders (linked to Client Corporations), Placements (with pay rate, bill rate, and linked Candidate and Client Corporation), and payroll reconciliation CSV (delivered separately for the finance team). Each phase emits a row-count reconciliation report before the next phase begins. Bullhorn Bulk API handles high-volume Candidate and Placement imports with batch chunking and retry logic on rate limit responses.
Cutover, validation, and automation rebuild handoff
We freeze Cavu HCM writes during cutover, run a final delta migration of any records modified during the migration window, then enable Bullhorn as the system of record for recruiting operations. We deliver the Automation and Workflow Inventory document to the customer's Bullhorn admin covering any Cavu workflow equivalents that need rebuilding in Bullhorn Workflow or Bullhorn Automation Engine. We support a one-week hypercare window where we resolve any reconciliation issues. We do not rebuild Cavu HR workflows as Bullhorn automations inside the migration scope; that is a separate engagement or an internal admin task.
