Overview

What this migration involves

Moving from Asure to Bullhorn is a category shift from HCM to recruiting ATS, not a platform upgrade. Asure organizes data around employment relationships: employees, payroll registers, PTO accrual ledgers, benefits enrollments, and tax configurations. Bullhorn organizes data around candidate pipelines and placements. We migrate what translates directly (Employees to Workers, Companies to ClientCorporations) and we flag what does not (payroll history, tax jurisdiction codes, accrual methods). We use Bullhorn's REST API with batch chunking and rate-limit handling for the Worker entity, and we map accrual balances to Bullhorn custom objects because Bullhorn ATS does not include a native accrual ledger. Workflows, payroll tax configurations, and benefit plan administration do not migrate; we deliver a written scope for your Bullhorn admin to configure these in the destination.

Leaving

Asure

What's pushing teams away

  • Customer support quality is the single most common complaint — slow response times, frequent staff turnover at Asure, and an inability to reach a knowledgeable human are cited across G2, Capterra, and Software Advice reviews.
  • Interface complexity — reviewers describe the UI as not user-friendly and harder to navigate than newer SMB payroll tools like Gusto or Rippling.
  • HR services are limited — Software Advice reviewers note Asure does not provide a dedicated HR person and communication is mainly via email, falling short for SMBs that expected outsourced HR advisory.
  • Bugs and ongoing issues lead to slow resolutions and recurring communication frustration during payroll cycles where speed matters most.
  • Pricing is opaque — no tier pricing is published, forcing every prospect through a custom quote process that complicates side-by-side evaluation.

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 Asure objects map to Bullhorn ATS & CRM

Each row shows how a Asure 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.

Asure

Employee

maps to

Bullhorn ATS & CRM

Worker

1:1
Fully supported

Asure Employee records map to Bullhorn Worker. Core fields (firstName, lastName, email, hireDate, terminationDate, department, jobTitle, employmentStatus) migrate directly. Compensation rate from Asure maps to Bullhorn custom fields on Worker because Bullhorn's standard pay structure is placement-centric (Bill Rate, Pay Rate on Placement) rather than employee-centric. We preserve the Asure employment type (full-time, part-time, contractor) as a custom field on Worker.

Asure

Company

maps to

Bullhorn ATS & CRM

ClientCorporation

1:1
Fully supported

Asure Company records map to Bullhorn ClientCorporation. The companyName becomes name, address fields map to the standard Bullhorn address block, and phone/website migrate as-is. ClientCorporation is created before Worker import so the ClientCorporationId lookup is satisfied at the moment of Worker insert. If the customer's Asure tenant is their own organization (internal HR use), we treat it as a special 'Internal' ClientCorporation in Bullhorn for reporting purposes.

Asure

Department

maps to

Bullhorn ATS & CRM

Department (lookup)

1:1
Fully supported

Asure departments migrate as Bullhorn Department records and are linked to Worker via the workersDepartmentId lookup. Department is populated before Worker import to avoid orphaned references. If Bullhorn's department structure is not yet configured, we create the department records during the schema phase.

Asure

Supervisor hierarchy

maps to

Bullhorn ATS & CRM

Supervisor lookup on Worker

lossy
Fully supported

Asure's reporting structure (manager-employee relationships) maps to Bullhorn's supervisorWorkerId lookup on the Worker entity. We resolve the supervisor reference by matching manager Employee IDs to Bullhorn Worker IDs after the Worker batch is loaded. Circular references and managers not yet in the system go to a reconciliation queue for the customer to resolve before finalization.

Asure

PTO Accrual Balances

maps to

Bullhorn ATS & CRM

Custom Object: PTO_Balance__c

1:1
Fully supported

Asure PTO and leave balances are stored as accrual ledgers per employee. Bullhorn ATS has no native accrual ledger; we create a PTO_Balance__c custom object (up to 10 on Front Office Growth/Enterprise, 2 on Bullhorn ATS) attached to the Worker record. Each accrual type (vacation, sick, personal) becomes a separate custom object instance. The accrual method (front-loaded, per-hours-worked, anniversary-based) is preserved in a custom field accrualMethod__c so the customer's Bullhorn admin can configure the correct accrual rules post-migration.

Asure

Benefits Enrollments

maps to

Bullhorn ATS & CRM

Custom Object: Benefits_Enrollment__c

1:1
Mapping required

Asure health, dental, vision, and voluntary benefit elections map to Bullhorn Benefits_Enrollment__c custom objects attached to Worker. Plan names, carriers, coverage tiers (employee, employee+spouse, family), and effective/termination dates migrate as fields. Bullhorn has no native benefits administration; these records serve as a reference archive for the customer's HR admin. Mid-year enrollments are flagged with a closed plan year marker to prevent recalculation triggers.

Asure

Payroll Register

maps to

Bullhorn ATS & CRM

Custom Object: Payroll_Register__c

1:1
Fully supported

Asure historical payroll register files (earnings, deductions, taxes, net pay per pay period) migrate to Bullhorn Payroll_Register__c custom objects. Bullhorn BackOffice (a separate module for staffing firm payroll) handles live payroll processing; the register history from Asure serves as an audit archive. We batch by pay period, map earnings codes to a custom Earnings_Type__c field, and attach each register record to the Worker. The customer's Bullhorn BackOffice admin uses this as reference when setting up pay rules.

Asure

Tax Configurations

maps to

Bullhorn ATS & CRM

Custom Object: Tax_Profile__c

1:1
Mapping required

Asure federal, state, and local tax withholding profiles per employee migrate to Bullhorn Tax_Profile__c custom objects attached to Worker. The jurisdiction codes, filing status, and allowances migrate as fields. Bullhorn does not process payroll tax calculations natively; these records are a migration artifact that the Bullhorn BackOffice admin or the customer's external payroll system uses to configure withholding in the destination. We audit the Asure export schema for truncated tax codes and request a manual jurisdiction list if the export appears incomplete.

Asure

HR Documents (W-4, I-9, offer letters)

maps to

Bullhorn ATS & CRM

ContentDocument / Note

1:1
Fully supported

Asure document repository files (W-4, I-9, offer letters, performance records) migrate as Bullhorn ContentDocument records linked via ContentDocumentLink to the Worker record. We extract attached files from Asure, match them to the corresponding Worker by employee ID or email, and attach them to the Bullhorn Worker. Note records with document summaries are created as supplementary references where file extraction is not feasible.

Asure

Time & Attendance Entries

maps to

Bullhorn ATS & CRM

Custom Object: Time_Entry__c

1:1
Mapping required

Asure clock-in/clock-out logs, shift codes, overtime rules, and time-off request statuses normalize to Bullhorn Time_Entry__c custom objects attached to Worker. Because Bullhorn ATS does not include a native time and attendance module, these migrate as historical reference records. Shift codes map to a custom shiftCode__c field, overtime flags to overtimeEligible__c, and time-off request status to a custom status__c picklist.

Asure

Employee Self-Service Portal Changes

maps to

Bullhorn ATS & CRM

Worker field update notes

lossy
Fully supported

Pending or recent self-service changes (address updates, direct deposit preferences, emergency contacts) from Asure's employee portal are flushed to a staging queue before migration. We apply these as direct field updates on the corresponding Worker record during import rather than importing them as separate notes. Any unresolved pending changes are reported in the reconciliation output for the customer to address manually.

Asure

Custom Fields (Asure)

maps to

Bullhorn ATS & CRM

Custom Fields (Bullhorn)

lossy
Fully supported

Asure custom fields on Employee, Company, and Benefits migrate to Bullhorn custom fields of matching type (text, number, date, picklist, checkbox) on the equivalent Bullhorn entity. Bullhorn supports custom fields via the Admin Field Mappings interface; we pre-create the field definitions during the schema phase using Bullhorn's metadata API. Picklist values migrate as-is; any Asure picklist values not in Bullhorn's allowed set are flagged for the customer's admin to validate.

Asure

Background Screening (MyHRScreens)

maps to

Bullhorn ATS & CRM

Note on Worker

1:1
Fully supported

Asure's background screening partnership with MyHRScreens does not expose records via standard export APIs. We flag this as a manual retrieval step: customers must request their screening history directly from MyHRScreens and upload the reports to Bullhorn as Notes or ContentDocument attachments on the corresponding Worker record. We include a data retrieval checklist in the migration handoff document.

Pair-specific challenges

  • Bullhorn ATS has no native HCM or payroll module

    Bullhorn is an ATS and recruiting CRM, not an HCM platform. Asure's payroll registers, tax withholding configurations, benefits enrollments, and accrual ledgers do not have native Bullhorn equivalents. We migrate these as reference data in Bullhorn custom objects, but Bullhorn does not process payroll, calculate accruals, or administer benefit plans without the Bullhorn BackOffice module (a separate billing product for staffing firms). We flag each HCM object during scoping so the customer knows what requires post-migration configuration in Bullhorn BackOffice or an external HR system.

  • PTO accrual method translation requires manual Bullhorn configuration

    Asure stores PTO balances as running accrual ledgers updated continuously, with methods that vary by plan: front-loaded annual grants, accrual-per-hours-worked, or anniversary-date-based accrual. Bullhorn has no accrual calculation engine. We freeze the balance snapshot at a defined pay-period cutover boundary, migrate it as a static balance to a Bullhorn custom object, and flag the accrual method in a custom field for the customer's Bullhorn admin to configure in their chosen accrual tool. If accrual resets fire during migration due to an open accrual period, the destination may overwrite the carryover.

  • State-specific tax configurations vary by Asure plan tier

    Asure's payroll tax handling is tiered: higher tiers expose more state and local tax jurisdictions in the export. Mid-market Asure plans may return fewer tax jurisdiction codes than the customer is actively using. We audit the customer's active tax jurisdictions before export, request a manual state list if the export schema appears truncated, and migrate the tax profile as a custom object in Bullhorn for the BackOffice admin to configure. Bullhorn BackOffice requires tax codes to be entered manually for each state the firm operates in.

  • Benefits plan-year dates can conflict with mid-year migration

    Asure benefits enrollments are tied to plan years with effective and termination dates. Migrating mid-year creates two overlapping enrollment periods across Asure and Bullhorn if both systems run in parallel. We isolate enrollment data to a closed plan year in the migration snapshot, flag mid-year qualifying event adjustments as exceptions, and do not import enrollments with open effective dates into Bullhorn's custom objects until the plan year resolves or the customer confirms the enrollment window has closed.

  • Custom Component Fields in Bullhorn are not for general use

    Bullhorn's Custom Component Fields are reserved for integrations and automations, not general data storage. The supported path for additional data is Bullhorn Custom Objects, which have field limits of 55 per object with up to 10 objects on Front Office Growth/Enterprise and 2 on Bullhorn ATS. We scope custom object requirements against the customer's Bullhorn edition tier during discovery and request Bullhorn Support to create each custom object via the official Custom Object Setup Spreadsheet before any data imports begin.

Migration approach

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

  1. Discovery and edition selection

    We audit the Asure tenant across modules in use (payroll, time and attendance, benefits, HR documents), custom fields, active accrual methods, plan-year enrollment data, and tax jurisdiction count. We pair this with a Bullhorn edition assessment: Bullhorn Team ($99/user) covers candidate and contact management for small agencies; Bullhorn Corporate adds API access and custom fields; Bullhorn BackOffice is required if the customer wants to run contractor payroll inside Bullhorn. The discovery output is a written migration scope with object inventory, a Bullhorn edition recommendation, and the list of HCM objects that have no Bullhorn native home (flagged for post-migration rebuild).

  2. Schema design in Bullhorn

    We design the Bullhorn destination schema using Bullhorn's REST metadata API. This includes provisioning Custom Objects (PTO_Balance__c, Benefits_Enrollment__c, Payroll_Register__c, Tax_Profile__c, Time_Entry__c) via the Custom Object Setup Spreadsheet submitted to Bullhorn Support, creating custom fields on the Worker entity for pay structure, accrual method, and employee type, and configuring the ClientCorporation and Department lookups before any data is loaded. Bullhorn BackOffice setup (if licensed) runs in parallel through Bullhorn's implementation team and is not part of the migration scope.

  3. Data extraction and staging from Asure

    We extract data from Asure in dependency order: Company records first, then Employee records with all standard and custom fields, then accrual balance snapshots at the defined cutover pay period, benefits enrollment records, payroll register history, time and attendance logs, and HR document files. We freeze active accrual updates at the cutover boundary, flush pending self-service portal changes before extraction, and audit tax jurisdiction completeness against the manual state list the customer provides. Extracted data is staged in a structured format for transformation.

  4. Transformation, deduplication, and validation

    We transform Asure records to Bullhorn entity schemas: Employee to Worker, Company to ClientCorporation, accrual ledgers to PTO_Balance__c instances per accrual type, benefits enrollments to Benefits_Enrollment__c, payroll registers to Payroll_Register__c, tax profiles to Tax_Profile__c, and time entries to Time_Entry__c. We deduplicate by email and employee ID, resolve supervisor lookups by matching to previously loaded Workers, and validate field type compatibility (dates, picklists, required fields) against Bullhorn's schema. Any unmapped Asure custom fields are reported for the customer to confirm before insertion.

  5. Migration in dependency order via Bullhorn REST API

    We load data into Bullhorn via the REST API in strict dependency order: ClientCorporation (first, as the Worker parent), Department, then Workers with Employee custom fields and supervisor lookups resolved, then Custom Objects (PTO_Balance__c, Benefits_Enrollment__c, Tax_Profile__c, Payroll_Register__c, Time_Entry__c) linked to Workers, then ContentDocument files for HR documents via Bullhorn's document upload API. Each phase emits a row-count reconciliation report showing records inserted, updated, skipped, and errored before the next phase begins. Bullhorn API rate limits are handled with exponential backoff and batch chunking.

  6. Cutover, validation, and handoff

    We freeze Asure writes during the cutover window, run a final delta migration of any records modified during migration, and disable the Asure integration as the system of record once Bullhorn is confirmed as active. We deliver a migration report with record counts per entity, a list of unmigrated records with reason codes, and the Benefits Plan-Year Conflict and Accrual Method Configuration checklists for the Bullhorn admin. Bullhorn BackOffice setup, accrual rule configuration, and benefits plan administration are separate workstreams outside this migration scope; we provide written guidance for each.

Most migrations land between two and four weeks for organizations under 500 employees with core employee and accrual data. Migrations with full benefits enrollments, payroll register history, time and attendance logs, and multiple Asure custom fields move to five to nine weeks because of custom object schema design in Bullhorn, accrual method translation, and multi-phase validation. Bullhorn's own onboarding team runs in parallel for platform setup, which does not count against the migration timeline.
