Overview
Rippling and Bullhorn serve different operational models, which makes this migration a domain pivot rather than a direct record copy. Rippling's unified worker graph treats an employed individual as a single record with linked employment, compensation, and PTO data. Bullhorn splits candidate data across Candidate, Contact, and Client Corporation objects with an explicit Placement record for every staffing assignment. We resolve that structural split at scoping: Rippling Workers who are staffing firm employees migrate to Bullhorn internal Users and Contacts; any Rippling Workers who represent the staffing firm's candidate pool migrate to Bullhorn Candidate records with a parallel to the Client Corporation record. Effective-dated employment history, compensation records, and PTO balances map into Bullhorn Custom Objects or Notes depending on the customer's Bullhorn edition tier, because Bullhorn does not natively store payroll, PTO accruals, or employment-history audit trails. Rippling Custom Objects are exported via the Rippling Custom Objects API, their schemas exported field-by-field, and the destination Bullhorn Custom Object definitions created before data migration begins. Bullhorn's Custom Object limits vary by tier — 10 with 55 fields on Enterprise, 2 on Bullhorn ATS, none on ATS Growth — which we surface during scoping so the customer can confirm their destination tier before mapping begins. Workflows, automations, device enrollment, and corporate card data do not migrate because Bullhorn is a recruiting and staffing CRM, not an HRMS with payroll or IT provisioning.

Object mapping
Each row shows how a Rippling 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.
Rippling
Worker
Bullhorn ATS & CRM
Candidate or User (split required)
1:manyRippling Workers represent employed individuals in the staffing firm's internal workforce and (if the firm is using Rippling ATS) their candidate pool. We split at scoping: internal employees of the staffing firm migrate to Bullhorn User (for system access) and Bullhorn Contact (for HR records); any Rippling Workers representing the firm's candidate pool migrate to Bullhorn Candidate records. The split is determined by the customer's business model and is documented before any data movement begins.
Rippling
Worker
Bullhorn ATS & CRM
Contact
1:1Rippling Workers who are internal employees of the staffing firm migrate to Bullhorn Contact records. Name, email, phone, work location, start date, and employment status transfer as Contact fields. The Worker's Rippling employee ID is preserved in a custom field for reconciliation.
Rippling
Job
Bullhorn ATS & CRM
Candidate (title field) or Job Order
lossyRippling Job records define titles, levels, and pay bands. For internal staffing firm employees, the Job title migrates as a Contact field or custom Contact field. For candidate-facing migration, Rippling Job titles map to Bullhorn Candidate preferred_title or to Bullhorn Job Order records depending on whether the customer is migrating historical job preferences or active job orders.
Rippling
Department
Bullhorn ATS & CRM
Client Corporation or Business Sector
1:1Rippling Departments map to Bullhorn Client Corporation records if the department represents a client organization of the staffing firm. Internal organizational departments (HR, Finance, Recruiting Operations) map to Bullhorn internal Corporate fields or are stored as Notes attached to the relevant Contact records. The mapping depends on whether the staffing firm uses Rippling to track their own org structure or their client roster.
Rippling
Work Location
Bullhorn ATS & CRM
Client Corporation (address) or Contact Address
1:1Rippling Work Locations carry legal entity and actual work-site addresses. We extract address fields (street, city, state, zip, country) and map them to Bullhorn Client Corporation address fields for client locations or Contact address fields for candidate work preferences. Jurisdiction flags are preserved in custom fields if regulatory reporting depends on them.
Rippling
Employment History
Bullhorn ATS & CRM
Candidate (custom fields) or Note
1:1Rippling tracks title changes, compensation changes, and transfers with effective dates as a chronological sequence. Bullhorn has no native employment history object. We sequence the changes by effective date and load them as Bullhorn Custom Object records (on Enterprise or Bullhorn ATS tier) or as Note records with a structured body (on ATS Growth tier). Each history entry carries the original effective date, change type, and prior and new values.
Rippling
Compensation Record
Bullhorn ATS & CRM
Candidate (custom fields) or Custom Object
1:1Rippling Compensation Records include pay rates, salary, bonuses, and equity information linked to Workers. Bullhorn stores placement pay rate and commission structure on Placement records but does not natively store internal employee compensation. We load compensation data as Bullhorn Custom Object records (Enterprise or Bullhorn ATS tier) or as structured Notes attached to the Contact, preserving pay type, amount, currency, and effective date.
Rippling
PTO Balance
Bullhorn ATS & CRM
Custom Object or Note
1:1PTO accruals and balances are time-sensitive. We snapshot balances at the migration cutover date, load them as Bullhorn Custom Object records with a balance date field, and flag whether the destination Bullhorn instance has a time-off tracking integration active. Bullhorn does not natively manage PTO accruals; if the customer needs this post-migration, a third-party integration or manual process is required. The snapshot date is recorded so auditors can verify the migration cutover point.
Rippling
Benefits Enrollment
Bullhorn ATS & CRM
Note or Custom Object
1:1Benefit plan assignments and carrier details are migratable from Rippling as of the cutover date. Active claim histories and FSA/HSA balances are flagged as out of scope because they are financial records requiring carrier portability documentation rather than HR record data. We migrate enrollment records as Bullhorn Notes with a structured template or as Custom Object records depending on the destination Bullhorn edition.
Rippling
Custom Object
Bullhorn ATS & CRM
Custom Object
1:1Rippling Custom Objects store structured data built on top of the standard worker graph. We export Custom Object records and field definitions via the Rippling Custom Objects API, pre-create the equivalent Bullhorn Custom Object schema (with field types mapped: text to text, date to date, number to number, picklist to picklist), and load records after schema validation. Bullhorn's Custom Object limits by tier are confirmed during scoping: Enterprise allows 10 Custom Objects with 55 fields each; Bullhorn ATS allows 2; ATS Growth allows none. If the customer's Rippling Custom Objects exceed the destination tier's limits, we recommend a tier upgrade or a Notes-based alternative during scoping.
Rippling
Document (Employee File)
Bullhorn ATS & CRM
Candidate Attachment or Note
1:1Employee documents — offer letters, contracts, tax forms — are exported from Rippling as file metadata and links. Actual file content depends on whether Rippling's file storage is accessible via API. We migrate document metadata as Bullhorn Notes with a URL reference to the original file, or as file attachments on the relevant Candidate or Contact record if the Bullhorn instance has document storage enabled.
Rippling
Owner
Bullhorn ATS & CRM
User
1:1Rippling Owners (HR admins, team managers) map to Bullhorn User records. We resolve owners by email match. Any Rippling Owner without a matching Bullhorn User is held in a reconciliation queue for the customer's Bullhorn admin to provision before record import resumes.

Migration approach
Discovery and business model clarification
We audit the source Rippling portal across active modules (Unity Platform tier, HCM, Payroll, IT, Spend), worker record count, Custom Object count and schemas, and any ATS integration data. The critical scoping question for Rippling to Bullhorn is whether the Rippling instance tracks the staffing firm's internal employees, their candidate pool, or both. We confirm the split rule (Worker to internal Contact vs Worker to Bullhorn Candidate) with the customer's primary contact before any data movement begins. We also confirm the customer's Bullhorn edition tier to validate Custom Object capacity against the Rippling Custom Object count.
Schema export and destination provisioning
We export Rippling Custom Object field definitions via the Custom Objects API, confirm field types and required flags, and provision the equivalent Bullhorn Custom Objects (or Notes fallback) based on the destination Bullhorn edition. If the Rippling Custom Object count exceeds Bullhorn's tier limit, we escalate to the customer for tier upgrade or schema consolidation before proceeding. We also create any required Bullhorn custom Contact or Candidate fields for compensation, PTO, and employment history before record migration begins.
Sandbox migration and reconciliation
We run a full migration into a Bullhorn Sandbox (or staging environment) using production-like data volume. The customer's Bullhorn admin reconciles record counts (Workers in, Candidates and Contacts in), spot-checks 25-50 random records against the Rippling source, and confirms the Worker-to-Candidate versus Worker-to-Contact split is working as designed. Any field mapping corrections, Custom Object schema mismatches, or tier-limit issues surface here before production migration begins.
Owner and user reconciliation
We extract every distinct Rippling Owner referenced on Worker, Job, Department, and Compensation records and match by email against the Bullhorn destination's User table. Any Rippling Owner without a matching Bullhorn User goes to a reconciliation queue. The customer's Bullhorn admin provisions missing Users (active or inactive depending on whether the original Rippling user is still active). Migration cannot proceed past this step because Bullhorn's record model requires a valid Owner reference on most standard objects.
Production migration in dependency order
We run production migration in record-dependency order: Bullhorn Users (validated), Client Corporations (from Rippling Departments that represent client relationships), Contacts (internal staffing firm employees from Rippling Workers), Candidates (candidate pool from Rippling Workers where applicable), Job Orders (if migrating active job data), Custom Objects (after standard object records are loaded, because they may have lookup dependencies), Compensation and PTO snapshots (as Bullhorn Custom Objects or Notes), and Document metadata (as Notes or file attachments). Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, validation, and workflow handoff
We freeze Rippling writes 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 Workflow and Automation inventory document to the customer's admin team, flagging that Rippling workflows require Bullhorn Automation configuration or manual rebuild as a separate engagement. We support a one-week hypercare window where we resolve any reconciliation issues raised by the customer's team. We do not configure Bullhorn Automation, rebuild Rippling workflows in Bullhorn, or set up Bullhorn integrations with job boards or background check providers as part of the standard migration scope.
