Overview

What this migration involves

Moving from Roubler to Bullhorn is a domain-shift migration. Roubler is a workforce management platform spanning recruiting, onboarding, rostering, time tracking, and payroll for internal teams. Bullhorn is an ATS and CRM built for staffing agencies managing external candidate pipelines and client relationships. The migration does not map directly because the object models serve different operational roles. We resolve this by treating Roubler Employees as Bullhorn Candidates (for placed or contingent workers), Roubler Positions as Bullhorn JobOrder definitions, Roubler Rosters as Placement assignment records, and Roubler Leave balances and Timesheets as custom fields on the Candidate record. Roubler's MYOB acquisition raises data residency and support continuity questions that we scope during discovery. Bullhorn's API does not include payroll or HRMS functionality, so payroll run summaries migrate as reporting records and any active payroll runs are flagged as write-locked before extraction. We do not migrate Roubler Workflows or integrations as code; Bullhorn's workflow model is fundamentally different and requires a separate rebuild by the customer's admin team.

Why teams make this switch

Two sides of the same decision

Leaving

Roubler logo

Roubler

What's pushing teams away

  • Customer support scores poorly (2.8/5) with users reporting slow response times and difficulty reaching knowledgeable staff for complex payroll or compliance queries.
  • Pricing is opaque and negotiated per contract with no public tier structure, making it hard for teams to budget or compare value before committing.
  • The API is still being expanded and does not yet cover all object types, limiting automation options and making migration engineering dependent on undocumented endpoints.
  • Australian-centric pre-configurations frustrate teams operating in the UK, South Africa, or other markets who must override defaults that do not match local employment law.
  • Teams outgrow the platform when they need granular custom objects or workflow automation beyond Roubler's templated approach to HR processes.

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 Roubler objects map to Bullhorn ATS & CRM

Each row shows how a Roubler 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.

Roubler

Employee

maps to

Bullhorn ATS & CRM

Candidate

1:1
Fully supported

Roubler Employee records map to Bullhorn Candidate. Core fields (firstName, lastName, email, phone, employmentType, startDate, position assignment) migrate directly. We flag any Employee without a valid email address because Bullhorn Candidate requires an email for the candidate record to be actionable. EmploymentType (full-time, part-time, casual) migrates to a custom Candidate field for segmentation. Employees who are internal admin staff rather than candidates to be placed are mapped to ClientContact instead; the customer specifies this split during scoping.

Roubler

Employee

maps to

Bullhorn ATS & CRM

ClientContact

1:1
Fully supported

Roubler Employees who are internal staffing agency staff (recruiters, account managers, back-office users) rather than candidates to be placed migrate to Bullhorn ClientContact. We extract these records by matching against the customer's specified user list or by identifying records with no position assignment in Roubler. ClientContact requires a firstName, lastName, email, and a linked ClientCorporation record, which we create as a placeholder corporation for the staffing agency's own organization.

Roubler

Position

maps to

Bullhorn ATS & CRM

JobOrder

1:1
Fully supported

Roubler Position records (role definitions with FTE value, task list, and employment model) map to Bullhorn JobOrder. The Position title becomes JobOrder title, FTE value maps to a custom field on JobOrder, and position tasks become JobOrder description bullets. Roubler's demand-based rostering data linked to POS integrations migrates as a custom field on JobOrder capturing the expected hours-per-week allocation.

Roubler

Roster / Shift

maps to

Bullhorn ATS & CRM

Placement

1:1
Fully supported

Roubler Roster and Shift records (time, location, assigned Employee) map to Bullhorn Placement when the assignment represents a placed candidate. The Shift start and end time becomes Placement startDate and endDate. Location migrates to Placement location field. Demand-based shift auto-generation data from POS integrations becomes a custom field on Placement. Open shifts and provisional assignments are flagged as draft Placement records for customer review before final import.

Roubler

Leave Balance

maps to

Bullhorn ATS & CRM

Candidate custom field

lossy
Fully supported

Roubler Leave entitlements, accrual history, and current balances map to custom fields on the Bullhorn Candidate record. Each leave type (annual, sick, long service) becomes a separate decimal field capturing the current balance. Accrual rates and effective dates migrate as metadata fields. Bullhorn does not have a native leave management object, so this data lives as flat custom fields on the Candidate. Leave rules tied to award interpretation cannot be preserved as active rules; we document the award name and entitlement structure in a separate compliance handoff sheet for the customer's HR admin.

Roubler

Timesheet

maps to

Bullhorn ATS & CRM

Placement custom field or Candidate custom field

lossy
Fully supported

Roubler Timesheet records link to rostered shifts and include clock-in/out events and hours worked. We aggregate timesheet data by pay period and migrate the totals as custom fields on the related Placement record (for placed workers) or as a historical timesheet summary attached to the Candidate record. Bullhorn Middle Office handles time capture for staffing firms post-migration; we document the migration of historical timesheet totals so the back-office team can reconcile against any payroll runs that continue in a separate payroll system.

Roubler

Payroll Run

maps to

Bullhorn ATS & CRM

Report record (non-standard)

lossy
Fully supported

Roubler Payroll Run summaries (gross/net amounts, pay period, run date) are exportable but have no Bullhorn equivalent because Bullhorn is an ATS/CRM and does not include payroll processing. We extract payroll run summaries as a structured CSV report and deliver it alongside the migration, flagging any runs that are still open or locked in Roubler at the time of extraction. If the customer uses Bullhorn Middle Office, we document the payroll run data mapping for integration into the back-office payroll module post-migration.

Roubler

Onboarding Record

maps to

Bullhorn ATS & CRM

Candidate custom field or Task

lossy
Fully supported

Roubler Onboarding records include tasks, document collection status, and employee setup steps. We migrate the current state of each onboarding workflow as custom fields on the Bullhorn Candidate (document collection status flags) and as Bullhorn Task records for pending onboarding steps that need completion post-migration. In-progress onboarding tasks do not transfer meaningfully as active workflows; we deliver a written onboarding task checklist for the customer's admin to complete in Bullhorn.

Roubler

Custom Field (Employee or Position)

maps to

Bullhorn ATS & CRM

Candidate custom field or JobOrder custom field

lossy
Fully supported

Roubler custom fields on Employee and Position objects migrate as custom fields on the corresponding Bullhorn object (Candidate or JobOrder). We export custom field names and values as flat key-value pairs and create matching custom fields in Bullhorn during the pre-migration schema setup phase. Field type mapping requires manual alignment: Roubler text fields map to Bullhorn text fields, date fields to date fields, picklist fields to picklist fields with the same option values.

Roubler

Integration configuration

maps to

Bullhorn ATS & CRM

No migration (rebuild required)

lossy
Fully supported

Roubler integrations with Xero, MYOB, QuickBooks Online, Workable, and POS systems store webhook URLs, credentials, and mapping rules that are not exportable via the API. Integration configuration must be rebuilt in Bullhorn or in a third-party integration layer post-migration. We deliver a written inventory of each active Roubler integration with its endpoint URLs, data flow direction, and object mapping so the customer's admin can reconfigure in Bullhorn or through Bullhorn's App marketplace.

Roubler

Document attachment

maps to

Bullhorn ATS & CRM

No migration (manual export required)

1:1
Fully supported

Employee documents (contracts, certifications, IDs) uploaded to Roubler are not retrievable through the public API. We cannot migrate binary file assets automatically. We alert the customer during discovery so they can export documents manually via Roubler's UI or through a screen-capture process before the migration window closes. We provide a document naming convention that maps each file to the corresponding Candidate record in Bullhorn for manual re-upload post-migration.

Roubler

Owner (Employee with system access)

maps to

Bullhorn ATS & CRM

User

1:1
Fully supported

Roubler Employees who have system access map to Bullhorn User records by email match. Any Roubler Employee without a matching Bullhorn User goes to a reconciliation queue for the customer's Bullhorn admin to provision before record import resumes. Bullhorn ATS Growth edition does not include API access; we confirm the destination Bullhorn edition during scoping and flag if API-disabled tiers are in use.

Pair-specific challenges

  • Bullhorn ATS Growth has no API access

    Bullhorn's ATS Growth edition (formerly Team Edition) explicitly excludes API access. If the customer's destination Bullhorn instance is on the Growth tier, we cannot use the Bullhorn REST API for data import. We confirm the Bullhorn edition during scoping and either recommend upgrading to a tier with API access (Starter and above) or fall back to Bullhorn's manual CSV import with field mapping through the Bullhorn Exchange custom mapping tool. Bullhorn's own documentation confirms API subscriptions and total API calls per month are gated features.

  • Document attachments are not accessible via Roubler's public API

    Employee documents (contracts, IDs, certifications) uploaded to Roubler are stored as attachments with no download endpoint in the documented API. We cannot migrate binary file assets automatically. We alert the customer during discovery so they can export documents manually before the migration window. We provide a file naming convention that maps each document to the corresponding Bullhorn Candidate record for manual re-upload. This is a manual step that must complete before cutover.

  • Bullhorn has no native payroll or leave management

    Bullhorn is an ATS and CRM purpose-built for staffing agencies. It has no native payroll processing, leave entitlement calculation, or award interpretation engine. Roubler leave balances and payroll run summaries do not have direct Bullhorn equivalents. We migrate leave balances as custom fields on Candidate and payroll run summaries as a structured data export, but Bullhorn Middle Office (a separate product tier) handles time capture and invoicing for staffing payroll, not the ATS core. The customer must plan a separate payroll solution or Bullhorn Middle Office integration if ongoing payroll processing is required.

  • Roubler's API is incomplete and expanding

    The Roubler API documentation states coverage will gradually be expanded to cover more types and fields as they stabilise. This means some objects may have undocumented endpoint behavior or unstable field names at migration time. We run a pre-migration API probe against every required object and fall back to CSV export or structured screen scrape for any gaps. We test endpoint reachability and response schema stability before committing to the extraction approach.

  • Roubler MYOB acquisition raises data residency questions

    Roubler was acquired by MYOB and operates as a subsidiary. MYOB's support infrastructure and data hosting locations (Sydney, Singapore, Dublin) may not fully align with the customer's current Roubler deployment. We scope the acquisition date, current hosting region, and MYOB support contact path during discovery. If the customer requires a specific data residency for the Bullhorn destination, we flag any data that should be extracted before contract renegotiations with MYOB/Roubler lock access or change data handling terms.

Migration approach

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

  1. Discovery and Bullhorn edition confirmation

    We audit the source Roubler instance for record counts (Employees, Positions, Rosters, Leave Balances, Timesheets, Payroll Runs), custom field definitions, active integrations (Xero, MYOB, POS systems), document attachment volume, and API endpoint reachability for each object type. We confirm the destination Bullhorn edition (ATS Growth, Starter, Core, Pro, or Enterprise) because ATS Growth excludes API access and requires a CSV-based import strategy. The discovery output is a written migration scope with object counts, an API probe report, and a Bullhorn edition recommendation.

  2. Schema design and custom field provisioning

    We design the Bullhorn destination schema. This includes creating custom fields on Candidate (leave balance fields, employment type, original Roubler employee ID) and on JobOrder (FTE value, position tasks, demand-based allocation fields). We create a placeholder ClientCorporation record for internal staffing agency staff that map to ClientContact. Bullhorn's custom field API names follow a naming convention; we match Roubler custom field names to Bullhorn custom field labels and let Bullhorn generate the API names. Schema is deployed into a Bullhorn Sandbox org first for validation before production migration.

  3. Sandbox migration and reconciliation

    We run a full migration into a Bullhorn Sandbox using a representative data sample (at minimum 100 records per object type). The customer's Bullhorn admin reconciles record counts, spot-checks field values against the Roubler source, and validates that Candidate records are correctly linked to JobOrders and Placements. Custom field mapping and data type alignment are corrected in this phase. The customer signs off the sandbox mapping before production migration begins.

  4. Document export and integration inventory

    We deliver a document export checklist to the customer for all employee documents (contracts, IDs, certifications) that cannot be retrieved via Roubler's API. The customer exports these manually from Roubler's UI and organizes them by employee name. We provide a file naming convention mapping each document to the corresponding Bullhorn Candidate record. We also deliver an integration inventory document listing each active Roubler integration with its endpoint configuration for rebuilding in Bullhorn or through a Bullhorn App marketplace alternative.

  5. Production migration in dependency order

    We run production migration in record-dependency order. ClientCorporation (placeholder) is created first. Candidates are imported with a mapping to ClientCorporation where applicable. JobOrders are created from Roubler Position definitions. Placements are created linking Candidates to JobOrders with Roster data (dates, location) mapped. Custom fields for leave balances, timesheet totals, and employment type are populated per Candidate. Timesheet aggregates and payroll run summaries are delivered as structured data exports alongside the migration. Each phase emits a row-count reconciliation report before the next phase begins.

  6. Cutover, validation, and handoff

    We freeze Roubler writes during cutover, run a final delta migration of any records modified during the migration window, and hand off Bullhorn as the system of record. We deliver the integration rebuild inventory and the document re-upload checklist to the customer's admin team. We support a one-week hypercare window for reconciliation issues. We do not rebuild Roubler integrations or onboarding workflows in Bullhorn inside the migration scope; those are separate configuration tasks for the customer's Bullhorn admin or a Bullhorn implementation partner.

Most migrations land between three and five weeks for accounts under 2,000 employees with straightforward roster and leave data and no multi-year history to extract. Migrations with multi-year roster history, active payroll runs, large leave balance records, or Bullhorn Enterprise as the destination move to eight to fourteen weeks because of custom field schema design, parent-record lookup resolution for Placements, and the document export coordination required before cutover.
