Overview

What this migration involves

Moving from ELMO Suite to Bullhorn is a category-shift migration, not a direct record copy. ELMO Suite is a cloud HRMS built around the employee as the central record, covering payroll, leave, performance, learning, and onboarding. Bullhorn is an ATS and CRM built around the candidate as the central record, with Jobs, Placements, and a back-office layer. These fundamentally different data models mean we must redesign the schema at migration time: employee-centric objects from ELMO map to candidate-centric objects in Bullhorn, payroll and compensation have no native Bullhorn equivalent and move into custom objects or are flagged for manual reconciliation, and custom performance review forms and engagement survey records require structured export as standalone data rather than native appraisal objects. Bullhorn's Custom Object limits vary by edition (none on ATS Starter, 2 on ATS Growth, 10 on Enterprise with 55 fields each), so we confirm the target edition before scoping any custom schema work. Workflows, automation rules, and learning paths do not migrate; we deliver a written inventory of these for the customer's Bullhorn admin to rebuild.

Why teams make this switch

Two sides of the same decision

Leaving

ELMO Suite logo

ELMO Suite

What's pushing teams away

  • Steep learning curve with clunky navigation frustrates users, particularly during the first weeks after go-live when workflows and module boundaries are unfamiliar.
  • Module synchronisation issues require manual updates in several functions — users report that data entered in one module does not propagate correctly to others.
  • Performance review framework is described as muddled with inconsistent review cycles and manual steps that defeat the purpose of an integrated system.
  • Integration limitations complicate connectivity to downstream finance systems, ERPs, and BI tools that organisations rely on for payroll-to-ledger or headcount reporting.

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 ELMO Suite objects map to Bullhorn ATS & CRM

Each row shows how a ELMO Suite 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.

ELMO Suite

Employee

maps to

Bullhorn ATS & CRM

Candidate

1:1
Fully supported

ELMO Employee records map to Bullhorn Candidate. Core fields (name, email, phone, address, employment type, start date) map directly to Candidate standard fields. The ELMO employment status (active, inactive, terminated) maps to Candidate status values. Any ELMO employee who is also a job applicant in the recruitment module migrates as a Candidate record with employment history carried as a Candidate custom object or note. The migration direction determines whether the Employee record is the primary artifact: if the destination is a staffing firm with Bullhorn as their ATS, Candidates are the primary record. We flag employees without recruitment context for manual Bullhorn User provisioning.

ELMO Suite

Employee

maps to

Bullhorn ATS & CRM

Corporate User

1:1
Fully supported

ELMO Employees who are internal recruiters, HR staff, or administrators map to Bullhorn Corporate Users. We resolve the mapping by email match. Any ELMO employee without a matching Bullhorn User goes to a reconciliation queue for the customer's Bullhorn admin to provision. OwnerId on Candidate and Job records must resolve to an active Bullhorn User, so User provisioning is a gate before record migration.

ELMO Suite

Recruitment / Applicant

maps to

Bullhorn ATS & CRM

Job Application

1:1
Fully supported

ELMO Recruitment module applicant records map to Bullhorn JobSubmission (also called Job Application in Bullhorn UI). Application status, source, submission date, and interview scores transfer to Bullhorn JobSubmission fields. Position title and department assignments reconcile during the field-mapping phase against the target Job record.

ELMO Suite

Job Order / Position

maps to

Bullhorn ATS & CRM

Job

1:1
Fully supported

ELMO recruitment job postings and position records map to Bullhorn Job. Job title, description, requirements, salary range, and status map directly to Bullhorn Job fields. The ELMO job type (permanent, contract, casual) maps to Bullhorn employmentType. We create Bullhorn Job records before JobSubmission records so that the JobOrder lookup is satisfied at insert time.

ELMO Suite

Onboarding Checklist

maps to

Bullhorn ATS & CRM

Bullhorn Onboarding (Able) or Custom Object

lossy
Fully supported

ELMO onboarding task lists and document checklists map to Bullhorn Onboarding (formerly Able) if the customer has the Bullhorn Onboarding add-on active. Task names, assignees, due dates, and completion status migrate as Onboarding task records. If Bullhorn Onboarding is not licensed, we create a custom object with task fields and flag the missing module for the customer's admin to activate or rebuild in Bullhorn.

ELMO Suite

Payroll / Compensation

maps to

Bullhorn ATS & CRM

Custom Object on Candidate or Placement

1:many
Fully supported

ELMO payroll records (pay groups, pay rates, salary history, superannuation) have no native Bullhorn equivalent. Bullhorn is not a payroll engine; it handles contractor invoicing via the Back Office add-on but not payroll processing. We create Bullhorn custom objects (up to 2 on ATS Growth, 10 on Enterprise) to hold compensation and superannuation records linked to Candidate or Placement. TFN declarations and Super Fund details export as structured data. ANZ-specific fields are preserved with field labels intact for compliance audit.

ELMO Suite

Leave Balances

maps to

Bullhorn ATS & CRM

Custom Object on Candidate

1:1
Mapping required

ELMO leave entitlements, accrual rules, and balance snapshots are source-system values that must be reconciled against the destination's accrual engine. Bullhorn has no native leave management. We export the leave balance as of the migration date and create a Bullhorn custom object linked to Candidate to store entitlement types (annual, sick, long service), accrual rates, and current balances. Leave approval workflows are not migrated; they require a separate HRMS or leave management tool post-migration.

ELMO Suite

Performance Review

maps to

Bullhorn ATS & CRM

Custom Object on Candidate

lossy
Fully supported

ELMO performance review cycles, objectives, goals, and appraisal ratings require a Bullhorn custom object because Bullhorn has no native performance management module. Rating scales, competency frameworks, and custom review forms vary significantly between ELMO organisations. We export review responses as structured records in a custom object and flag custom forms for post-migration manual reconciliation. If the customer uses fewer than 2 custom objects on ATS Growth or 10 on Enterprise, we scope which review data is highest priority for migration.

ELMO Suite

Learning Record

maps to

Bullhorn ATS & CRM

Custom Object on Candidate

1:1
Fully supported

ELMO course completions, certifications, and skill profiles migrate to a Bullhorn custom object on Candidate. Custom learning paths and due dates require field-level mapping. Completion status and expiry dates are preserved. Bullhorn has no native LMS; the custom object approach preserves the learning record as a candidate skill and certification reference without requiring an external LMS integration.

ELMO Suite

Organisational Structure

maps to

Bullhorn ATS & CRM

Corporate User field or Department custom field

lossy
Fully supported

ELMO departments, cost centres, and business units map to Bullhorn Corporate User department and division fields, or to a custom field on User if the Bullhorn edition supports it. Reporting lines and manager assignments preserve as manager links on User records. The Bullhorn org chart does not replicate ELMO's full hierarchical structure; we map the business unit layer that is relevant for ATS workflow routing.

ELMO Suite

Engagement (activities, notes, interactions)

maps to

Bullhorn ATS & CRM

Note, Task, or Appointment on Candidate

1:1
Fully supported

ELMO engagement records (candidate interactions, interview notes, communications) map to Bullhorn Note, Task, or Appointment records linked to the Candidate. Activity timestamps and engagement types preserve. Bullhorn's API supports all standard engagement entities; we use batch processing with rate-limit handling to move large engagement volumes. Note rich text and attachment links migrate as ContentDocument with ContentDocumentLink to the Candidate.

ELMO Suite

Expense Record

maps to

Bullhorn ATS & CRM

Bullhorn Back Office expense module or Custom Object

1:1
Fully supported

ELMO expense claims, receipts, approval workflows, and reimbursement status migrate as expense records if the customer has Bullhorn Back Office active. Category codes and approval routing re-map to Bullhorn expense categories. If Back Office is not licensed, we create a custom object for expense records and flag the module gap.

Pair-specific challenges

  • Category shift from HRMS to ATS changes the migration data model

    ELMO Suite is an HRMS with the employee as the central record. Bullhorn is an ATS and CRM with the candidate as the central record. Payroll, leave entitlements, and compensation have no native Bullhorn equivalent and must move into custom objects (up to 2 on ATS Growth, 10 on Enterprise) or be flagged for manual reconciliation in a separate HRMS. We redesign the schema at scoping time to decide which ELMO modules migrate to Bullhorn and which require an alternative destination. Migrations that skip this schema redesign step arrive in Bullhorn with orphaned records and missing lookup relationships.

  • Bullhorn edition limits on Custom Objects constrain schema scope

    Bullhorn ATS Starter has no Custom Objects. ATS Growth has 2 Custom Objects with 55 fields each. Enterprise has 10 Custom Objects with 55 fields each. ELMO organisations frequently use 4 or more distinct HRMS modules (payroll, leave, performance, learning, onboarding, expenses). We confirm the target Bullhorn edition before scoping custom object creation. If the edition does not support the required custom object count, we prioritise the highest-value migration objects (compensation, leave, onboarding) and flag the remainder for a Bullhorn upgrade or a parallel HRMS tool.

  • ELMO module-to-module data lag corrupts migration snapshots

    G2 reviewers consistently report that data entered in one ELMO module may not propagate immediately to others — for example, a new employee's start date entered in recruitment may not appear in payroll for hours or days. We snapshot all ELMO modules independently rather than relying on a single cross-module export, and we timestamp every snapshot to identify records that changed between module exports. This prevents stale cross-references from being carried into Bullhorn as active data.

  • Custom performance review forms and engagement surveys resist direct mapping

    ELMO organisations frequently build custom review templates with non-standard rating scales, competency questions, and survey frameworks that have no Bullhorn equivalent. Bullhorn has no native performance management or survey object. We export review responses and survey data as structured records in a Bullhorn custom object and flag custom forms for post-migration reconciliation. The customer receives a structured data file of all review responses and survey records for manual re-entry or a third-party performance management integration.

  • Bullhorn API rate limits require chunking and backoff for large candidate imports

    Bullhorn's REST API enforces per-entity rate limits. Large candidate imports (over 10,000 records) require batch chunking, exponential backoff on 429 responses, and careful ordering to satisfy Bullhorn's entity dependency requirements (Users before Candidates, Jobs before JobSubmissions, Candidates before Placements). We implement retry logic and chunk sizing tuned to Bullhorn's documented limits. Without this handling, large imports either time out or produce partial datasets.

Migration approach

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

  1. Discovery and Bullhorn edition confirmation

    We audit the source ELMO environment across all active modules (payroll, time, performance, learning, onboarding, recruitment, expenses, engagement surveys) and count records by type. We pair this with a Bullhorn edition assessment: ATS Starter ($99/user/mo, no custom objects) covers straightforward candidate and job migrations; ATS Growth ($182/user/mo, 2 custom objects) covers most single-module migrations with compensation or leave as a custom object; Enterprise ($315/user/mo, 10 custom objects) is required if multiple HRMS modules need custom objects or the engagement volume exceeds 200,000 records. The discovery output is a written migration scope with a Bullhorn edition recommendation and a gap analysis of ELMO modules against Bullhorn object equivalents.

  2. Schema design and custom object scope

    We design the destination Bullhorn schema based on the edition-confirmed custom object budget. Compensation, leave, performance, and learning migrate as custom objects on Candidate. Onboarding migrates to Bullhorn Onboarding (Able) if licensed, or to a custom object if not. We create all custom object schemas (field names, types, picklist values, required constraints) in a Bullhorn Sandbox first. Bullhorn's Custom Object Setup Sheet template (available in Bullhorn Hub) defines the field limits per custom object (55 fields total, up to 20 of which can be pickers, dropdowns, or mini-pickers). We validate the schema against the ELMO data inventory before production migration begins.

  3. Sandbox migration and reconciliation

    We run a full migration into a Bullhorn Sandbox using production-like data volume. The customer's Bullhorn admin reconciles record counts (Candidates in, Contacts in, Jobs in, JobSubmissions in, Placements in, engagement records in), spot-checks 25-50 random records against the ELMO source, and validates custom object field values. Any mapping corrections happen in the Sandbox phase. Bullhorn Sandbox migrations can take from several minutes for a few thousand rows to 16 hours for millions of rows, per Bullhorn Plugin migration documentation.

  4. Owner reconciliation and User provisioning

    We extract every distinct ELMO employee referenced as a recruiter, hiring manager, or HR admin on candidate, job, and placement records and match by email against the Bullhorn destination org's User table. Owners without a matching Bullhorn User go to a reconciliation queue. The customer's Bullhorn admin provisions any missing Corporate Users (active or inactive depending on whether the original ELMO employee is still active). Migration cannot proceed past record import because OwnerId on Candidate, Job, and Placement requires a valid Bullhorn User reference.

  5. Production migration in dependency order

    We run production migration in Bullhorn's entity dependency order: Corporate Users (manual provisioning validated), Corporations (from ELMO company records), Contacts (client records), Candidates (from ELMO Employee and Applicant records), Jobs (from ELMO job postings), JobSubmissions (from ELMO applications), Placements (from ELMO placement or offer records), Onboarding tasks (to Bullhorn Onboarding or custom object), Activity history (Notes, Tasks, Appointments via Bullhorn REST API with chunking and rate-limit handling), Custom Objects for payroll, leave, performance, and learning (last because they have lookups to Candidates and Users). Each phase emits a row-count reconciliation report before the next phase begins.

  6. Cutover, validation, and rebuild handoff

    We freeze ELMO 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 recruitment. We deliver the Workflow, automation, and custom performance form inventory document to the customer's Bullhorn admin team with rebuild recommendations per object. We support a one-week hypercare window where we resolve any reconciliation issues raised by the customer's team. Bullhorn Workflows (Bullhorn Automation, formerly Herefish) and ELMO learning paths do not migrate as code; these are documented separately for the customer's admin to rebuild.

Context on both ends of the pair

ELMO Suite logo

ELMO Suite

Source

Strengths

  • Modular product suite lets organisations migrate incrementally — payroll first, then performance, then learning — without a single big-bang cutover.
  • All-in-one data model consolidates employee records, payroll, time, and engagement into a single vendor ecosystem, reducing reconciliation overhead.
  • Employee self-service reduces HR team administrative load for routine leave requests, payslip access, and profile updates.
  • Multi-country payroll capabilities support ANZ businesses with employees across states and territories, handling award and legislative variations.
  • Consolidated reporting across modules gives HR leaders a single view of headcount, time, and performance without pulling exports from separate systems.

Weaknesses

  • Steep learning curve and clunky navigation documented across G2 reviews, meaning time-to-value after migration is slower than competitors.
  • Module synchronisation issues mean data entered in one module may not propagate correctly to others, creating reconciliation work for HR teams.
  • Performance management module is widely described as inconsistent, with manual steps that erode the value of integrated reviews.
  • Integration limitations complicate connectivity to downstream finance systems and BI tools, which can block payroll-to-ledger automation after migration.
  • No published public pricing creates uncertainty for organisations evaluating ELMO against competitors with transparent per-user rates.

Most migrations land between three and five weeks for accounts under 5,000 candidate records with no custom objects and a clean module inventory. Migrations with custom objects (payroll, leave, performance, learning as Bullhorn custom objects), large engagement histories (over 200,000 activity records), or Bullhorn Onboarding integration move to eight to fourteen weeks because of custom object schema design, Sandbox validation cycles, and Bullhorn API rate-limit handling. Bullhorn's own documentation states small staffing firms go live in two weeks and larger agencies in two to six weeks for standard ATS setup; the ELMO migration adds scoping, schema design, and data reconciliation time on top.
