Overview
Alongside is an HRMS platform with a documented customer base of seven organizations in Canada, the UK, and the Netherlands. It has no publicly available API, data model, or pricing documentation in our research corpus. Bullhorn is a staffing-focused ATS and CRM serving over 4,400 organizations globally with a tiered object model (Candidate, ClientCorporation, ClientContact, JobOrder, Opportunity, Placement, Task, Event) accessible via REST and Bulk APIs. Migrating from Alongside to Bullhorn is a schema-first engagement: we cannot apply field-mapping automation without first inspecting the customer's Alongside data export to establish what objects and fields actually exist in their instance. We then map those to Bullhorn's standard entity types, flag any Alongside-specific fields that have no Bullhorn equivalent, and deliver a written inventory of workflows and automations requiring rebuild. Bullhorn's Custom Object tier limits (10 for Front Office Growth/Enterprise, 2 for Bullhorn ATS, none for ATS Growth) constrain how many Alongside custom entities can migrate natively.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Alongside 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.
Alongside
Candidate (Alongside)
Bullhorn ATS & CRM
Candidate
1:1Alongside candidate records map to Bullhorn Candidate. We inspect the customer's Alongside export to identify which fields correspond to Candidate.firstName, Candidate.lastName, Candidate.email, Candidate.phone, Candidate.address, Candidate.education, and Candidate.employmentHistory. Historical status values from Alongside (active, placed, archived) map to Bullhorn Candidate.status. Resume files migrate as CandidateResume attached via ContentDocumentLink. If Alongside stores candidate skills or certifications as custom fields with no standard Bullhorn equivalent, we flag them for Bullhorn Custom Object creation (subject to edition tier limits: 10 for Front Office Growth/Enterprise, 2 for Bullhorn ATS, none for ATS Growth).
Alongside
Company/Client (Alongside)
Bullhorn ATS & CRM
ClientCorporation
1:1Alongside client or company records map to Bullhorn ClientCorporation. We extract company name, address, industry, phone, website, and revenue tier from the Alongside export and map them to the corresponding Bullhorn ClientCorporation fields. ClientCorporation is created before any ClientContact or JobOrder import so that the lookup relationship is satisfied at insert time. Any Alongside-specific fields without a Bullhorn standard equivalent are flagged for custom field or Custom Object placement.
Alongside
Contact (Alongside)
Bullhorn ATS & CRM
ClientContact
1:1Alongside contact records attached to a client map to Bullhorn ClientContact, linked via ClientCorporationID. We extract name, email, phone, title, and department from the Alongside export and resolve the parent ClientCorporation by company name match. If Alongside does not enforce a strict client-contact hierarchy and contacts are flat, we create a default ClientCorporation record for orphaned ClientContacts or, if the customer prefers, map them directly to Candidate if they represent contractor contacts.
Alongside
Job/Position (Alongside)
Bullhorn ATS & CRM
JobOrder
1:1Alongside job or position records map to Bullhorn JobOrder. We extract title, description, requirements, location, employment type (full-time, contract, part-time), pay range, and status (open, filled, closed) from the Alongside export. JobOrder is inserted after ClientCorporation and before any CandidateJobApplication or Placement, satisfying the ClientCorporationID and OwnerID references. Status values from Alongside map to Bullhorn JobOrder.status.
Alongside
Application/Submission (Alongside)
Bullhorn ATS & CRM
JobSubmission
1:1Alongside application or submission records linking a Candidate to a Job map to Bullhorn JobSubmission. The mapping resolves CandidateID and JobOrderID by email match and job title match respectively. Submission date, status (applied, screening, interview, offer, hired, rejected), and source (referral, job board, direct) migrate from Alongside. If Alongside stores rejection reason or interview feedback as custom fields, these map to JobSubmission custom fields or notes attached to the submission.
Alongside
Placement (Alongside)
Bullhorn ATS & CRM
Placement
1:1Alongside placement records (a Candidate placed into a Job at a Client) map to Bullhorn Placement. The mapping resolves CandidateID, JobOrderID, and ClientCorporationID at migration time. Placement startDate, endDate, payRate, billRate, and status (active, completed, terminated) migrate directly. If Alongside stores onboarding documents or contract references as attachments, these migrate as ContentDocumentLink records attached to the Placement.
Alongside
Deal/Opportunity (Alongside)
Bullhorn ATS & CRM
Opportunity
1:1If Alongside stores deal or opportunity records tied to a ClientCorporation (e.g., a staffing firm's commercial pipeline separate from placed jobs), these map to Bullhorn Opportunity. The mapping resolves ClientCorporationID, OwnerID, and Opportunity amount. Stage values from Alongside map to Bullhorn Opportunity.stageName, with Salesforce Record Types and Sales Processes configured if the customer uses multiple deal pipelines. This object is optional depending on Alongside schema scope.
Alongside
Engagement: Call (Alongside)
Bullhorn ATS & CRM
Task (TaskSubtype = Call)
1:1Alongside call records map to Bullhorn Task with TaskSubtype=Call. We extract call date, duration, disposition (if stored), and outcome from the Alongside export and set Task.ActivityDate, Task.CallDurationInSeconds, and Task.Description. The Task WhoId points to the resolved Candidate or ClientContact. Call recording URLs migrate to custom Task fields. Activity ordering is preserved by setting ActivityDate to the original Alongside timestamp.
Alongside
Engagement: Email (Alongside)
Bullhorn ATS & CRM
EmailMessage + Task
1:1Alongside email engagement records map to Bullhorn EmailMessage (the content) linked to an Activity Task record (the timeline entry). The email body, subject, from, to, and cc fields migrate to EmailMessage. The Task WhoId links to the Candidate or ClientContact; the WhatId links to the related JobOrder, Placement, or ClientCorporation. If Alongside stores email threads as flat records without thread IDs, we preserve the conversation context by ordering EmailMessages by timestamp.
Alongside
Engagement: Meeting (Alongside)
Bullhorn ATS & CRM
Event
1:1Alongside meeting records map to Bullhorn Event. We extract startDateTime, endDateTime, location, title, and description from the Alongside export. Attendee resolution links to EventRelation records pointing at the migrated Candidates, ClientContacts, and Users. Recurring meeting series from Alongside are flagged as a known limitation: we can migrate individual Event instances but series recurrence rules require Bullhorn calendar rebuild post-migration.
Alongside
Engagement: Note (Alongside)
Bullhorn ATS & CRM
Note
1:1Alongside notes attached to Candidates, Jobs, or Companies map to Bullhorn Note records linked via ContentDocumentLink to the parent record. Note body migrates as plain text or rich text depending on formatting detected in the Alongside export. If Alongside stores notes with author and timestamp metadata, these map to Note.Title and Note.Body. File attachments embedded in notes migrate as separate ContentDocument records attached to the Note.
Alongside
Engagement: Task (Alongside)
Bullhorn ATS & CRM
Task
1:1Alongside task records map to Bullhorn Task with Status, Priority, Subject, and ActivityDate preserved. Task assignment resolves the Alongside assigned user to a Bullhorn User by email match. Recurring tasks from Alongside are flagged as a Bullhorn limitation: Bullhorn does not natively support recurring task series, so recurring Alongside tasks are migrated as individual Task records with a custom field indicating the original recurrence pattern for manual rebuild in Bullhorn.
Alongside
Custom Object (Alongside)
Bullhorn ATS & CRM
Custom Object (Bullhorn)
1:1Alongside custom entities or fields without standard object equivalents migrate to Bullhorn Custom Objects. We first establish which Alongside fields are custom versus standard by inspecting the export. Bullhorn requires a Support ticket with a completed Custom Object Setup Spreadsheet to provision each Custom Object before REST API access. Each Bullhorn Custom Object supports 55 fields across a limited set of edit types (text, dropdown, checkbox, picker). We coordinate this provisioning step with Bullhorn Support as part of discovery and map each Alongside custom entity to its corresponding Bullhorn Custom Object API name.
Alongside
Document/Attachment (Alongside)
Bullhorn ATS & CRM
ContentDocument + ContentVersion
1:1Alongside uploaded documents (resumes, contracts, onboarding forms, job descriptions) migrate as Bullhorn ContentVersion records linked via ContentDocumentLink to the parent entity (Candidate, JobOrder, Placement, ClientCorporation). We extract file name, MIME type, size, and content blob from the Alongside export. ContentVersion.Title maps to the original file name. We do not migrate document version history beyond the current version in a single migration run.
Alongside
Tag/Label (Alongside)
Bullhorn ATS & CRM
Multi-Select Picklist
lossyAlongside tags or labels stored as multi-value fields migrate to Bullhorn multi-select picklist fields on the relevant entity. If Alongside uses tags for content classification (e.g., skill tags on Candidate), we create a custom Candidate skill_tag__c multi-select field with the Alongside tag values as picklist options. The customer chooses whether to normalize tag values (deduplicate similar tags) or preserve them verbatim during scoping.
Alongside
User/Employee (Alongside)
Bullhorn ATS & CRM
User
1:1Alongside user or employee records that represent recruiter accounts map to Bullhorn User. We resolve each Alongside user by email match against the Bullhorn destination User table. Owners referenced on Candidate, JobOrder, Placement, and Opportunity records use this User resolution. Users without a matching Bullhorn account go to a reconciliation queue for the customer's Bullhorn admin to provision before record import resumes.
Alongside
Candidate Status/Pipeline (Alongside)
Bullhorn ATS & CRM
Candidate status or custom workflow stage
lossyAlongside's candidate pipeline stages (if structured as a workflow rather than a flat status field) map to Bullhorn's Candidate status values or to a Bullhorn custom pipeline workflow. Bullhorn's standard Candidate object uses a status field with values like 'New Lead', 'Contacted', 'Interview', 'Offer Extended', 'Hired', 'Not Qualified'. We compare Alongside's stage names against Bullhorn's standard values and recommend a status mapping, flagging any Alongside stages that require custom field or Custom Object representation.
Alongside
Billing/Invoice Record (Alongside)
Bullhorn ATS & CRM
Placement (billing fields) or Invoice (custom)
lossyIf Alongside stores billing or invoice records tied to Placements (e.g., timesheet summaries, commission calculations, invoiced amounts), we map these to Bullhorn Placement billing fields (Placement.payRate, Placement.billRate, Placement.durationWeeks) where available. Additional billing records without a Bullhorn standard field map to a Bullhorn Custom Object for invoicing, or are exported as a CSV inventory for the customer's finance team to reconcile post-migration. This decision is made during scoping based on Alongside's actual billing schema.

Migration approach
Data export request and schema discovery
We request a full data export from Alongside on behalf of the customer. Export formats may include CSV, JSON, or a direct database dump depending on what Alongside's admin interface or API can produce. We inspect the export to identify all object types, field names, data types, record counts, relationships, and any Alongside-specific custom fields. We produce a written Alongside schema document and a gap analysis identifying which objects have Bullhorn standard equivalents, which require Custom Object creation, and which require manual reconciliation post-migration. This phase typically takes one to two weeks depending on Alongside's export responsiveness.
Bullhorn edition assessment and Custom Object provisioning
We assess the customer's target Bullhorn edition (Starter, Core, Pro, or Front Office Growth/Enterprise) against the Alongside schema complexity. If Alongside exports contain custom entities exceeding Bullhorn ATS tier limits (2 Custom Objects), we recommend the customer upgrade to Front Office Growth or Enterprise before migration. We open a Bullhorn Support ticket with the completed Custom Object Setup Spreadsheet to provision the required Custom Objects and obtain REST API credentials (API username, password, and OAuth2 tokens) for the migration user account.
Field mapping design and sandbox validation
We design the field-level mapping from each Alongside object to its Bullhorn equivalent. We map standard Bullhorn fields directly and flag Alongside-specific fields requiring Custom Object placement or custom fields. We map Alongside engagement records (calls, emails, meetings, notes, tasks) to Bullhorn Task, Event, EmailMessage, and Note objects with parent-record resolution (WhoId, WhatId, ClientCorporationID). We run a validation migration into the customer's Bullhorn Sandbox using production-like data volume. The customer's Bullhorn admin spot-checks 25-50 random records against the Alongside source and signs off the mapping before production migration begins.
Owner and user reconciliation
We extract every distinct Alongside user or owner referenced on Candidate, Job, Placement, and Opportunity records and match by email against the Bullhorn destination User table. Alongside users without a matching Bullhorn User go to a reconciliation queue. The customer's Bullhorn admin provisions missing Users (active or inactive depending on whether the Alongside user is still active). Bullhorn requires a valid OwnerId on most standard objects before record insert; migration cannot proceed past this step until all OwnerId references are resolved.
Production migration in dependency order
We run production migration in record-dependency order: Custom Objects (first if required for lookup resolution), ClientCorporation, ClientContact, Candidate, JobOrder, Opportunity (if present), Placement, JobSubmission, then Engagement history (Tasks, Events, EmailMessages, Notes). Documents and attachments migrate as ContentVersion records with ContentDocumentLink to the parent entity. Each phase emits a row-count reconciliation report before the next phase begins. We use Bullhorn's REST API for standard inserts and Bulk API 2.0 for large engagement histories, with batch chunking, exponential backoff on rate limit responses, and parent-record lookup resolution.
Cutover, delta sync, and automation handoff
We freeze Alongside writes during cutover. We run a final delta migration of any records modified during the migration window. We validate record counts across all object types against the Alongside source. We deliver the Alongside automation inventory document to the customer's Bullhorn admin team with Bullhorn Workflow, Bullhorn Automation, and Bullhorn Process Builder recommendations for each discovered Alongside rule. We support a one-week hypercare window for reconciliation issues. We do not rebuild Alongside automations as Bullhorn Workflows inside the migration scope; that is a separate engagement or internal admin task.
