Overview

What this migration involves

Moving from a standalone Payroll Automation platform to Bullhorn is a staffing back-office consolidation, not a simple record copy. Payroll Automation platforms store employee compensation, tax withholdings, benefit deductions, and garnishment orders with paycheck-level granularity. Bullhorn ATS stores candidate, contact, company, job, and placement records with an integrated back-office layer for time management and payroll export. We bridge the two by extracting at the paycheck line level from the source, mapping employees to Bullhorn candidate and contact records, preserving compensation history and garnishments in Bullhorn custom fields, and sequencing the migration so that existing placements in Bullhorn have time records and pay rates reconciled before the first payroll export. Bullhorn Automation workflows and the Herefish/Bullhorn Automation suite do not migrate; we deliver a written inventory of every active automation for the customers admin to rebuild post-migration.

Why teams make this switch

Two sides of the same decision

Leaving

Payroll Automation

What's pushing teams away

  • Per-employee pricing scales poorly as headcount grows, and many platforms charge additional fees for add-ons like HR support or workers comp.
  • Tax filing errors and missed deadlines have occurred when users fail to manually review auto-calculated amounts before submission.
  • Onboarding and setup complexity creates friction, with some providers charging one-time fees and requiring weeks of configuration.
  • Customer support responsiveness varies widely, with ADP and Paychex users reporting slow resolution times during critical periods.
  • Integration limitations force companies already using competing accounting platforms to maintain duplicate records or manual workarounds.

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 Payroll Automation objects map to Bullhorn ATS & CRM

Each row shows how a Payroll Automation 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.

Payroll Automation

Employee

maps to

Bullhorn ATS & CRM

Candidate + Contact (dual-record mapping)

1:many
Fully supported

Payroll Automation employee records map to Bullhorn Candidate (for recruiting pipeline and sourcing history) and Bullhorn Contact (for back-office and billing relationships). The mapping uses SSN or employee ID as the dedupe key. We preserve the full employee address, tax withholding status (W-4 equivalents), and emergency contact data in Bullhorn custom fields on both records. The customer's Bullhorn admin determines whether the employee also requires a separate Contact record for client-billing purposes or whether the Candidate record alone carries the payroll data.

Payroll Automation

Compensation History

maps to

Bullhorn ATS & CRM

Placement custom fields

1:1
Mapping required

Wage rates, salary changes, bonus schedules, and overtime rules from the Payroll Automation source migrate as custom fields on the Bullhorn Placement record. Bullhorn Placement stores payRate, billRate, and margin; compensation history beyond the current rate is stored in Bullhorn custom fields (customText or currency fields) since the standard Placement object does not natively track historical pay changes. We sequence compensation history import after the Placement record is created so the lookup is satisfied at insert time.

Payroll Automation

Payroll Run

maps to

Bullhorn ATS & CRM

Time & Labor + Payroll Export

lossy
Fully supported

Bullhorn does not run payroll internally; it exports time and labor data to a payroll provider via Bullhorn Time & Labor. We map Payroll Automation pay run headers to Bullhorn time period configurations and map individual pay run lines to Bullhorn time entries (RTE or Transaction Uploader format) so that historical payroll data feeds into the Bullhorn time record structure. The export format aligns with Bullhorns Payroll Export and Accounts Payable Export processes.

Payroll Automation

Tax Withholdings

maps to

Bullhorn ATS & CRM

Candidate/Contact tax configuration fields

1:1
Fully supported

Federal, state, and local tax withholding configurations from the Payroll Automation source migrate to Bullhorn custom fields on the Candidate or Contact record. Bullhorns standard ATS does not include a native tax withholding configuration object, so we use custom fields to store tax jurisdiction, filing status, and allowances. For customers using Bullhorn with Greenshades or another integrated payroll partner, we map these to the partners tax configuration schema instead.

Payroll Automation

Benefit Deductions

maps to

Bullhorn ATS & CRM

Placement custom fields + Bullhorn deduction codes

1:many
Mapping required

Health insurance contributions, 401(k) deferrals, HSA and FSA deductions, and voluntary benefit deductions from Payroll Automation map to Bullhorn Placement custom fields and custom deduction codes in Bullhorns back-office configuration. Each deduction type (medical, dental, vision, retirement, HSA, FSA) gets its own code to support W-2 generation and payroll export. Employer match logic is preserved as notes on the Placement record for the back-office team to configure in the payroll export layer.

Payroll Automation

Garnishments

maps to

Bullhorn ATS & CRM

Placement custom fields + compliance notes

1:1
Mapping required

Child support orders, tax levies, and wage garnishment orders carry effective dates, dollar limits, and statutory deduction percentages that cannot be approximated. We extract garnishment records from Payroll Automation with effective date, expiration date, maximum deduction per period, and court order reference, and map them to Bullhorn Placement custom fields with a garnishment compliance flag. Bullhorns back-office team uses these to configure garnishments in the payroll export layer. We do not file garnishment order notifications; that is a legal compliance step the customer handles directly.

Payroll Automation

PTO Balances

maps to

Bullhorn ATS & CRM

Bullhorn custom fields or third-party PTO module

1:1
Mapping required

Accrued PTO, sick leave, and other leave balances from Payroll Automation migrate to Bullhorn custom fields on the Candidate or Contact record. Bullhorn ATS does not include a native PTO accrual engine; we store current balance and accrual rate for reference. If the customer uses Bullhorn with a third-party PTO management integration, we map the balance data to the integration's required fields. For staffing firms where PTO is managed by the worksite employer rather than the staffing agency, we scope this object based on the customer's operational model.

Payroll Automation

Org Structure

maps to

Bullhorn ATS & CRM

Department + Bullhorn user teams

1:1
Fully supported

Departments, cost centers, job titles, and reporting hierarchies from Payroll Automation map to Bullhorn Department and to Bullhorn team-based user permissions. Bullhorn does not have a native org chart object, but Department is used for branch-level time approval routing, billing segmentation, and user visibility controls. We map cost centers to Bullhorn custom fields on Placement for back-office billing reports.

Payroll Automation

Direct Deposit / Banking Information

maps to

Bullhorn ATS & CRM

Bullhorn back-office payroll export

lossy
Fully supported

Employee banking information for direct deposit from Payroll Automation is extracted and mapped for import into the customer's payroll provider (Greenshades, ADP, or another). Bullhorn does not store banking details internally; it passes payroll data to the export layer. We extract the bank name, routing number, account number, and deposit allocation (percentage or flat amount) and deliver it as a structured CSV for the payroll provider onboarding team. We do not store banking data in Bullhorn.

Payroll Automation

Worker Classification

maps to

Bullhorn ATS & CRM

Placement recordType

lossy
Fully supported

W-2 employee versus 1099 contractor classification from Payroll Automation maps to Bullhorn Placement recordType. Staffing firms distinguish between regular W-2 placements (paid through payroll export) and 1099 contractor assignments (paid through accounts payable export). We map the source classification to Bullhorn Placement recordType so that the back-office payroll versus AP routing is set correctly at migration time.

Payroll Automation

Job Order / Position

maps to

Bullhorn ATS & CRM

JobOrder

1:1
Fully supported

Active job orders or position records from the Payroll Automation source that represent open headcount migrate to Bullhorn JobOrder. JobOrder captures job title, requirements, department, and status. For staffing firms, JobOrder is the recruiting-side record paired with Placement (the filled, billable assignment). We map open positions to Bullhorn JobOrder with status set appropriately based on whether the position is still recruiting or has been filled and transitioned to a Placement.

Payroll Automation

Time Entry Records

maps to

Bullhorn ATS & CRM

Bullhorn Time & Labor entries

1:1
Fully supported

Historical time entries from Payroll Automation migrate to Bullhorn Time & Labor format (BTE). Bullhorn supports VTC, Web Time Entry, Rapid Time Entry, and Transaction Uploader formats. We map source time entries to RTE or Transaction Uploader format depending on whether the source data includes individual punch records or summary hours. Each time entry links to the corresponding Bullhorn Placement record via the assignment ID. Overtime hours, holiday rates, and double-time flags map to Bullhorn earn codes for correct payroll export.

Pair-specific challenges

  • Bullhorn does not run payroll internally

    Bullhorn is an ATS and CRM with an integrated time and labor export layer, not a payroll processor. The payroll run itself happens in Greenshades, ADP, UKG, or another payroll provider connected to Bullhorn via export. When migrating from a Payroll Automation platform that runs payroll end-to-end, the migration extracts all employee and payroll data and divides it between Bullhorn (for candidate, placement, and time data) and the target payroll provider (for tax withholding, benefit deduction, and garnishment execution). We coordinate with both platforms during migration to ensure the split is clean and no employee record is orphaned between the two systems.

  • Paycheck line-item detail requires API extraction not CSV export

    Payroll Automation platforms flatten paycheck detail into summary checks or journal entries in their built-in CSV exports, stripping tax withholding lines, benefit deduction lines, and garnishment lines. Migrating only the net paycheck amount destroys the W-2 accuracy and IRS audit trail. We extract at the paycheck line level via the source platform API where available, preserving every tax, deduction, and garnishment entry. If the source platform does not expose line-item data via API, we document the gap and recommend the customer request a full payroll register export directly from the provider before migration begins.

  • Bullhorn custom objects require Bullhorn Support ticket to create

    Bullhorn does not allow end users to create custom objects through the admin UI; a Bullhorn Support ticket must be submitted with a completed Custom Object Setup Spreadsheet. Custom objects are available on Candidate, Contact, Company, Opportunity, Job, and Placement with field limits that vary by edition (Front Office Growth/Enterprise supports 10 custom objects with 55 fields each; Bullhorn ATS supports 2; ATS Growth supports none). We factor Bullhorn Support ticket submission into the migration timeline and account for the edition-specific ceiling when scoping the number of custom objects needed to store compensation history, garnishments, and benefit deductions.

  • Bullhorn Automation workflows do not migrate

    Bullhorn Automation (formerly Herefish) automations built around placement-based triggers, billing validation, and payroll error detection do not migrate as code. Automations are tied to Bullhorn list criteria, field values, and notification routing that are not portable. We deliver a written inventory of every active Bullhorn Automation with its trigger conditions, action steps, and notification routing for the customers Bullhorn admin to rebuild post-migration. This includes any automations configured to catch missing pay rates, end dates in the past, or margin thresholds before timesheet export.

  • Garnishment orders carry legal enforceability dates that cannot be approximated

    Wage garnishment orders from Payroll Automation have effective dates, court order numbers, maximum deduction percentages, and expiration dates that are legally binding. Approximating or omitting these values exposes the employer to legal liability. We extract garnishment records in full from the source platform, map them to Bullhorn Placement custom fields with a compliance flag, and deliver a separate garnishment inventory document to the customers back-office team for re-entry into the payroll export layer. We do not file garnishment order updates with courts or agencies; that is a legal compliance step the customer handles.

Migration approach

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

  1. Discovery and payroll split decision

    We audit the Payroll Automation source across employee record volume, paycheck history depth (number of pay periods), active deduction codes, active garnishment orders, PTO balance inventory, and tax jurisdiction count. We pair this with a Bullhorn edition review (Front Office Growth/Enterprise vs Bullhorn ATS vs ATS Growth) to confirm the custom object ceiling matches the migration scope. We also identify the target payroll provider for the back-office split (Greenshades, ADP, UKG, Paylocity, or another) and confirm the export format requirements. The discovery output is a written migration scope that defines what moves to Bullhorn, what moves to the payroll provider, and what requires manual re-entry.

  2. Schema design and custom object provisioning

    We design the Bullhorn destination schema including custom fields on Candidate, Contact, and Placement for compensation history, tax withholding, benefit deductions, garnishment orders, PTO balances, and cost center data. If the migration requires more custom objects than the Bullhorn edition supports, we identify which data lives in custom fields versus custom objects and document the trade-off. We submit the Custom Object Setup Spreadsheet to Bullhorn Support and coordinate provisioning before data migration begins. Schema design also includes mapping Bullhorn Placement recordTypes for W-2 versus 1099 classification and configuring earn codes for overtime, holiday, and double-time rates.

  3. Sandbox migration and reconciliation

    We run a full migration into a Bullhorn Sandbox using production-like employee and payroll run data volume. The customers Bullhorn admin reconciles record counts (Candidates in, Contacts in, Placements in, time entries in), spot-checks 25-50 random employee records against the Payroll Automation source, and validates that pay rates, tax withholdings, and garnishment amounts are accurate in the Bullhorn custom fields. Any mapping corrections happen in sandbox before production migration begins.

  4. Payroll provider coordination and export preparation

    We extract employee banking information, tax withholding configurations, and garnishment order details from the Payroll Automation source and format them for import into the target payroll provider. This step runs in parallel with the Bullhorn migration and requires the customers payroll provider account to be active and configured for onboarding. We deliver a structured CSV of direct deposit allocations, tax jurisdiction data, and garnishment records to the payroll provider onboarding team. Bullhorn does not store banking data; it passes through to the payroll export layer.

  5. Production migration in dependency order

    We run production migration in record-dependency order: Placement records first (with recordType, payRate, and billRate), then Candidate and Contact records (with compensation history and tax configuration), then time entries linked to Placements via assignment ID, then garnishment records and PTO balances as Placement custom fields. Direct deposit and banking data are delivered separately to the payroll provider and are not stored in Bullhorn. Each phase emits a row-count reconciliation report before the next phase begins.

  6. Cutover, validation, and automation rebuild handoff

    We freeze Payroll Automation writes during cutover, run a final delta migration of any employee or time records modified during the migration window, then enable Bullhorn as the recruiting and placement system of record with time data flowing to the payroll provider. We deliver the Bullhorn Automation inventory document to the customers admin team. We support a one-week hypercare window where we resolve any reconciliation issues. We do not rebuild Bullhorn Automation workflows, time approval routing rules, or payroll export configurations inside the migration scope; those are separate configuration or implementation engagements.

Most migrations land between three and five weeks for staffing firms under 500 employees with clean deduction codes, no garnishment orders, and a defined payroll provider already configured. Migrations with active garnishment orders, multi-state tax withholding across more than five jurisdictions, large payroll run histories (over 50,000 paycheck line items), and Bullhorn Time & Labor setup move to eight to fourteen weeks because of line-item extraction time, garnishment validation, and the custom object provisioning wait time from Bullhorn Support.
