Overview
Moving from Arcoro to BambooHR is a transition from a construction-specialist HRIS to a general-purpose HR platform built for small and mid-sized businesses. Arcoro organizes its data around employees, applicants, time entries tied to job cost codes, and OSHA compliance records within construction-specific modules. BambooHR uses a simpler employee-centric data model that lacks Arcoro's construction-ERP integration depth and its job cost structure. We extract Arcoro employee records with their custom fields, normalize non-standard employment-status values (prevailing wage, apprenticeship classifications) to BambooHR's standard picklist, and import payroll history as read-only compensation records. Applicant data from Arcoro's ATS maps into BambooHR's hiring module with resume files preserved. We do not migrate Arcoro workflows, onboarding workflow states, or construction-specific job cost code structures as functional equivalents in BambooHR. We deliver a written inventory of every active Arcoro workflow and onboarding workflow with a BambooHR rebuild guide for your HR team to recreate post-migration.

Object mapping
Each row shows how a Arcoro object lands in BambooHR, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Arcoro
Employee
BambooHR
Employee
1:1Arcoro employee records map directly to BambooHR's employee table with standard fields (name, contact info, employment dates, department, job title) mapping 1:1. Arcoro's CoreHR exports include custom fields that map to BambooHR custom fields; we discover field names and types via Arcoro's export configuration before migration. Construction-specific certifications from Arcoro map to BambooHR's credential tracking with expiration dates and alerts preserved. Employment status normalization is required because Arcoro uses construction-specific classifications (prevailing wage, apprenticeship program) that are not BambooHR standard values; we map each status to a BambooHR picklist value during scoping and flag any that require custom status creation.
Arcoro
Applicant
BambooHR
Applicant (BambooHR Hiring)
1:1Arcoro ATS applicant records map to BambooHR's applicant records in the hiring module. Arcoro stage names (Applied, Phone Screen, Interview, Offer, Hired, Rejected) map to BambooHR stage names where a direct equivalent exists. Scorecards, interview notes, and sourcing channel metadata migrate as informational fields. Resume file attachments migrate by uploading to BambooHR's onboarding packet for candidates who advance to hire. Arcoro's sourcing channel tracking has no direct BambooHR equivalent; we preserve the channel as a custom field for reporting and flag it as requiring manual entry for new applicants post-migration.
Arcoro
Onboarding Task
BambooHR
Onboarding Task
1:1Arcoro onboarding workflows are task-based with document checklists tied to construction onboarding requirements. We migrate completed onboarding tasks and checklist status as informational records in BambooHR. Arcoro's active workflow states (which tasks are pending, which are skipped) do not map to BambooHR's task model; we deliver a written handoff document describing each active Arcoro onboarding workflow with its trigger, assigned tasks, document checklist, and recommended BambooHR equivalent. The customer's HR team recreates workflow states and active task assignments in BambooHR post-migration.
Arcoro
Time Entry
BambooHR
Time Off and Historical Hours
1:1Arcoro time entries contain hours worked, date, and optionally job cost code and overtime calculations. We extract hours by employee and pay period as historical data loaded into BambooHR as informational records linked to the employee. Arcoro's GPS-enabled clock-in/out data has no BambooHR equivalent; we preserve the raw timestamps as a custom field note for the employee's record. Job cost codes from Arcoro cannot migrate as functional cost allocations in BambooHR since BambooHR has no job costing structure; we flatten them to an informational custom field. The Arcoro next-day sync delay means we schedule extraction for the calendar day following the end of the pay period.
Arcoro
Payroll Record
BambooHR
Employee Compensation History
1:1Arcoro payroll history includes earnings, deductions, and tax withholdings per pay period. We export historical payroll as read-only records and load them into BambooHR's employee compensation history, preserving pay period dates, gross pay, net pay, and major deduction categories. Arcoro pay frequencies (weekly, biweekly, semimonthly, monthly) map to BambooHR pay types. If Arcoro stores pay rates in a different currency from BambooHR's configured currency, we flag the discrepancy during scoping. Payroll data loads last in the migration sequence to preserve audit trails and avoid retroactive changes after cutover.
Arcoro
Benefit Enrollment
BambooHR
Benefit Election (informational)
1:1Arcoro benefit records contain active plans, coverage levels (employee, employee plus spouse, family), and election dates. We import benefit enrollments as informational records linked to the employee in BambooHR. Plan names and coverage tier labels migrate as text fields; we flag any Arcoro plans with no clear BambooHR benefit module equivalent so the HR team can create new benefit offerings post-migration. Active benefit elections are preserved with their effective dates for audit continuity, but BambooHR's benefit administration features are not automatically populated from Arcoro data.
Arcoro
Certification
BambooHR
Employee Certification
1:1Arcoro certifications include issue dates, expiration dates, and renewal alert settings for OSHA cards, trade licenses, and apprenticeship completions. We extract the full certification history and map it to BambooHR's employee certification tracking with expiration dates preserved. Arcoro's construction-specific certification types (OSHA 10-hour, OSHA 30-hour, trade-specific credentials) may require type classification during scoping; we create a crosswalk mapping each Arcoro type to a BambooHR credential type and flag any that cannot be cleanly categorized for manual review.
Arcoro
Custom Field (CoreHR)
BambooHR
Custom Field
lossyArcoro CoreHR supports custom fields on employee records. We discover custom field names and types via Arcoro's CoreHR export configuration interface before migration. Custom fields map to BambooHR custom fields of the equivalent type (text, number, date, dropdown) with any Arcoro validation rules applied as value transformations in our migration layer. Arcoro CoreHR custom exports must be pre-configured before they can be automated; we include a pre-flight check in the migration plan at least one week before the extraction window to confirm export configurations are in place.
Arcoro
Document and Attachment
BambooHR
Employee File
1:1Arcoro stores documents per employee including onboarding paperwork, signed agreements, performance reviews, and OSHA forms. We export available attachments and map them to BambooHR's employee file management, linking each document to the corresponding employee record. Arcoro document metadata (document type, upload date, uploaded by) migrates as file notes. BambooHR's file upload API accepts documents under 10 MB per file; we chunk larger files and flag any that exceed this limit for manual upload post-migration.
Arcoro
Job Cost Code
BambooHR
Custom Field (informational only)
lossyArcoro job cost codes reference the construction ERP and encode job, phase, cost code, and cost class dimensions simultaneously. BambooHR has no job costing structure; we extract job cost codes from Arcoro time entries and flatten them into an informational custom field on the employee record. The crosswalk table built during field mapping captures each Arcoro job cost code and its meaning so the HR team and accounting department have a reference for post-migration reconciliation. Any job cost codes without a clear mapping go to a flag list for the customer's finance team to resolve.

Pair-specific challenges
Migration approach
Discovery and Arcoro API credential request
We request Arcoro BDAPI credentials on the customer's behalf and audit the licensed Arcoro modules by reviewing contract documentation (required because Arcoro does not publish pricing or tier feature matrices). We inventory all employee records, applicant data, time entries, payroll history, benefit enrollments, certifications, and custom fields. We identify every non-standard employment status value in Arcoro and map it to a BambooHR picklist value during this phase. We also schedule the extraction window in coordination with the customer's payroll cycle, accounting for Arcoro's next-day time entry sync delay.
BambooHR configuration and field mapping design
We configure the BambooHR API connection in the customer's test environment and review the destination field schema. We design the custom field structure in BambooHR for Arcoro fields with no direct equivalent (custom employment statuses, certifications, job cost codes). We build the employment status crosswalk and the job cost code flattening rule. We confirm that Arcoro CoreHR custom exports are configured at least one week before the extraction window. The output of this phase is a signed mapping document that the customer reviews before any data moves.
Sandbox migration and reconciliation
We run a full migration into a BambooHR test environment using production-like data volume. We reconcile record counts for employees, applicants, time entries, payroll periods, certifications, and documents against the Arcoro source. We spot-check 25-50 records for field-level accuracy and confirm that employment status values, compensation amounts, and certification expiration dates are correctly mapped. The customer signs off on the sandbox migration before we schedule the production migration date.
Production migration in dependency order
We migrate data in dependency order: employees with normalized employment status and certifications (first), applicants with resume files linked to onboarding packets (second), time entries and payroll history as read-only informational records (third), and benefit enrollments (fourth). Custom fields and job cost codes load alongside the employee record. Each phase emits a reconciliation row-count report before the next phase begins. We handle the Arcoro next-day sync delay by scheduling extraction after the nightly sync completes and coordinating with the customer's payroll cycle.
Cutover, validation, and workflow handoff
We freeze writes in Arcoro at cutover and run a final delta migration for any records modified during the migration window. We validate record counts in BambooHR match the final Arcoro export and confirm that employment status values, payroll amounts, and certification expiration dates are accurate. We deliver the Arcoro workflow and onboarding workflow inventory with a BambooHR rebuild guide to the customer's HR team. We support a five-business-day hypercare window for reconciliation issues. We do not rebuild Arcoro workflows in BambooHR; that work is handled by the customer's HR team using the delivered guide.
