Overview
Moving from Savvy HRMS to Bullhorn is a domain shift from a general HRMS covering the full employee lifecycle to a recruitment-focused ATS and CRM built for staffing agencies. The migration centers on the recruitment module: Candidate profiles, application stage history, resume documents, and job order data map into Bullhorn Candidate, ClientContact, JobOrder, and Placement records. Savvy HRMS employee records that represent placed candidates or contract workers migrate to Bullhorn as Candidate records; pure employment records without recruitment context may not have a natural landing in Bullhorn and are flagged during scoping. We use the Bullhorn REST API for the migration, falling back to CSV exports from the Savvy HRMS admin dashboard when API access is unavailable or undocumented. Bullhorn Custom Objects are provisioned through Bullhorn Support before migration using the Custom Object Setup Spreadsheet. Workflows, leave accrual rules, payroll configurations, and compliance settings do not migrate; we deliver a written inventory for the customer's Bullhorn admin to rebuild post-migration.

Object mapping
Each row shows how a Savvy HRMS 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.
Savvy HRMS
Recruitment Candidates
Bullhorn ATS & CRM
Candidate
1:1Savvy HRMS candidate profiles, application stages, interview scores, and offer details map to Bullhorn Candidate. Stage history from the Savvy HRMS Recruitment module converts to Bullhorn Candidate status and to the corresponding JobOrder submission pipeline. We preserve the original application date, source channel, and any scoring values in Bullhorn custom fields. If the candidate has been placed through Savvy HRMS as a contract worker, the placement record maps to Bullhorn Placement with start date, end date, and pay rate preserved.
Savvy HRMS
Employee (recruitment context)
Bullhorn ATS & CRM
Candidate or ClientContact
lossySavvy HRMS employee records represent either current employees or contract workers. Employees with recruitment history in the Savvy HRMS Recruitment module map to Bullhorn Candidate. Pure administrative employees without recruitment context map to Bullhorn ClientContact if they represent an organization contact, or are flagged as out-of-scope if they represent an internal HR record with no Bullhorn equivalent. We confirm this boundary during scoping based on the customer's Bullhorn usage model.
Savvy HRMS
Job Histories
Bullhorn ATS & CRM
Candidate Employment History
1:manySavvy HRMS job history records attached to an employee or candidate split into multiple Bullhorn Candidate Employment records. Each history row maps to company name, job title, start date, end date, and description. We concatenate employment periods and map the most recent employer to the Candidate's primary employment record.
Savvy HRMS
Employee Profile
Bullhorn ATS & CRM
Candidate
1:1Core employee fields (name, email, phone, date of birth, address, emergency contact) map to Bullhorn Candidate standard fields. Employee ID from Savvy HRMS becomes a custom field on Candidate. Date of hire from Savvy HRMS maps to the Candidate's dateAdded or a custom hire_date__c field depending on Bullhorn edition configuration.
Savvy HRMS
Contract Labor Entries
Bullhorn ATS & CRM
Candidate (Contract) + Custom Object
lossySavvy HRMS contract worker records (contract dates, billing rates, assignment details) map to Bullhorn Candidate with a contract type designation, and to a Bullhorn Custom Object if the customer requires detailed contract terms tracking (start date, end date, hourly/daily rate, vendor name, assignment status). Bullhorn Support provisions the Custom Object before migration using the Custom Object Setup Spreadsheet.
Savvy HRMS
Documents and Attachments
Bullhorn ATS & CRM
Candidate Resume + ContentDocument
1:1Savvy HRMS employee documents including resumes, ID copies, offer letters, and contracts export as binary files and attach to the corresponding Bullhorn Candidate record. Resume content also feeds Bullhorn's resume parsing on insert so that candidate fields (skills, education, work history) are auto-populated from the parsed content. We preserve the original file name and mime type as ContentDocument metadata.
Savvy HRMS
Leave Policies and Balances
Bullhorn ATS & CRM
Custom Object or Note
1:1Savvy HRMS leave types, accrual rules, and employee balance amounts at the migration cut-off date do not have a native Bullhorn equivalent because Bullhorn is a recruiting ATS, not a leave management system. We map leave balances to a Bullhorn Custom Object provisioned per the customer's Bullhorn edition if the customer wants to maintain leave history in Bullhorn for compliance or auditing. Otherwise, we export leave data as a CSV handoff document with employee ID, leave type, balance, and accrual date.
Savvy HRMS
Payroll Runs and Payslips
Bullhorn ATS & CRM
Note or External Reference
1:1Savvy HRMS payroll records (earnings, deductions, net pay per pay period) have no direct Bullhorn equivalent. Bullhorn is not a payroll system. We export payslip summary data as a structured CSV with employee ID, pay period, earnings, deductions, and net pay, and attach it as a Note on the Candidate or store it as an external reference. Full payroll rebuild requires a separate payroll system implementation outside the Bullhorn migration scope.
Savvy HRMS
Performance Appraisals
Bullhorn ATS & CRM
Custom Object
lossySavvy HRMS review cycles, ratings, and competency scores map to a Bullhorn Custom Object (appraisal_history__c) with fields for review date, rating, reviewer, and competency scores. Bullhorn Support provisions this custom object before migration. We preserve the review period and score values at the cut-off date; active review cycles in progress are documented separately for the customer's Bullhorn admin to recreate.
Savvy HRMS
Learning and Development Records
Bullhorn ATS & CRM
Custom Object
lossySavvy HRMS course enrollments, completion statuses, and quiz scores map to a Bullhorn Custom Object (training_history__c) with fields for course name, enrollment date, completion date, status, and score. Certification expiry dates are flagged as requiring re-triggering in Bullhorn or a learning management system. Bullhorn Support provisions this custom object before migration.
Savvy HRMS
Attendance Records
Bullhorn ATS & CRM
Note or External Reference
1:1Savvy HRMS attendance data (clock-in/clock-out timestamps, overtime, grace period adjustments) does not have a Bullhorn equivalent because Bullhorn is a recruiting and placement platform. We export attendance records as a CSV handoff grouped by employee ID and pay period. Customers needing attendance tracking in Bullhorn should consider Bullhorn Time & Expense or a third-party time-tracking integration.
Savvy HRMS
Custom Fields and Properties
Bullhorn ATS & CRM
Custom Fields on Candidate
lossySavvy HRMS organizations frequently add custom properties to standard objects. We enumerate all active custom fields during scoping, map each to a Bullhorn custom field on the Candidate entity, and confirm field types (text, drop-down, date, number) match Bullhorn's supported custom field types. Bullhorn custom fields use the field label as the display name and an auto-generated API name with __c suffix.

Migration approach
Discovery and export method confirmation
We audit the Savvy HRMS instance to confirm which modules are active (Recruitment, Performance, Learning, Contract Labor), estimate record counts for each object type, and identify the available export method. We submit an API discovery request to Savvy HRMS or, if no API is confirmed, plan for CSV exports from the admin dashboard. We simultaneously confirm the customer's Bullhorn edition (ATS Growth, ATS, Front Office Growth, or Enterprise) to determine the Custom Object cap. The discovery output is a written migration scope document listing confirmed export method, record counts, active modules, Bullhorn edition, and the Custom Object list.
Bullhorn Custom Object provisioning and schema setup
We work with the customer to complete the Bullhorn Custom Object Setup Spreadsheet for all required custom objects (leave balances, performance history, training records, contract labor details). The customer submits the spreadsheet to Bullhorn Support for provisioning. We configure Bullhorn Field Maps to rename any standard field labels to match the customer's naming conventions. All Bullhorn schema setup (custom fields, record types, dropdown values) is validated in a Bullhorn Sandbox before production migration begins.
Data extraction from Savvy HRMS
We extract all active records from Savvy HRMS using the confirmed export method. For CSV exports, we pull candidate profiles, employee records, job histories, document files (resumes, offer letters, ID copies), recruitment stage history, contract labor entries, and any custom field data. We agree on a migration cut-off date with the customer so that leave balances and attendance records are frozen at a consistent point in time. Any records created after the cut-off date remain in Savvy HRMS as the system of record until the Bullhorn go-live date.
Data transformation and mapping validation
We transform the extracted Savvy HRMS data against the migration mapping specification. Candidate records are built with employment history split, resume file attachment, and stage mapping applied. Contract labor entries are formatted for the Bullhorn Custom Object schema. Leave balance and attendance data are exported as CSV handoff documents. We run the transformation in a Bullhorn Sandbox environment and reconcile record counts, field population rates, and document attachment counts before any production data is loaded.
Production migration in dependency order
We run the production migration in dependency order: custom object schema validation first, then Candidate records (with resume attachments and employment history), then ClientContact records for organizational contacts, then JobOrder records for any open positions, then Custom Object records for leave balances and performance history, then Placement records for any placed contract workers. Bullhorn REST API handles inserts with batch chunking and exponential backoff on rate limit responses. Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, validation, and handoff documentation
We freeze writes to Savvy HRMS during cutover and run a final delta migration of any records modified during the migration window. We validate the Bullhorn instance against the mapping specification, spot-checking candidate records, resume attachments, and custom object fields. We deliver the leave balance, attendance, and payroll CSV handoff documents to the customer. We deliver the Bullhorn Workflow inventory and Bullhorn Automation rebuild recommendations as separate written documents. We support a one-week hypercare window for reconciliation issues and do not rebuild workflows, sequences, or payroll configurations inside the migration scope.
