Overview

What this migration involves

Moving from EPAY HCM to BambooHR is a simplification migration: EPAY bundles recruiting, onboarding, HR, benefits, payroll, tax filing, and labor allocation under a single fixed per-employee contract, while BambooHR focuses on core HRIS (employee records, onboarding, benefits, payroll at some tiers, and performance reviews) with an open REST API. EPAY has no public API, so all data extraction requires vendor-assisted export coordination; we request exports early in scoping and validate record counts before beginning transformation. We preserve the complete compensation timeline (pay rates, bonuses, effective-dated changes) in BambooHR's payRate and payType fields, and we flag that garnishment orders, tax filing history, job costing assignments, and ACA compliance data have no native BambooHR equivalent and must be retained in EPAY or documented for manual re-entry. Workflows, automation rules, and time-tracking schedules do not migrate; we deliver a written inventory of these for the customer's admin to rebuild in BambooHR or a separate scheduling tool.

Why teams make this switch

Two sides of the same decision

Leaving

EPAY HCM logo

EPAY HCM

What's pushing teams away

  • Pricing is opaque — there is no public pricing page and prospects must request a quote, which causes delays and uncertainty during vendor evaluation and migration planning.
  • No documented public API means integrations with downstream accounting, ERP, or business intelligence tools require manual data handling or custom development, creating dependency on EPAY's own export tools.
  • Customers report frustration with reporting and analytics limitations — the built-in dashboards are considered functional but not sufficient for deep workforce insight needs without supplementary tools.
  • Switching away from EPAY is complicated because the platform bundles recruiting, onboarding, HR, benefits, payroll, and tax filing — leaving requires a coordinated multi-system migration rather than a simple data export.
  • Customer reviews note a steep learning curve for administrators configuring complex pay rules, union agreements, and multi-state tax setups, which can extend implementation timelines significantly.

Choosing

BambooHR logo

BambooHR

What's pulling them in

  • Lowest friction entry point for SMBs moving off spreadsheets — intuitive interface means most teams are functional within days, not weeks.
  • Consolidation value: BambooHR merges ATS, onboarding, HR records, time-off, and payroll into a single pane of glass that employees never need to leave.
  • Volume discounts applied automatically by headcount, so pricing scales predictably as the company grows without renewal negotiations.
  • BambooHR reports most customers go live in four to six weeks, making it a realistic commitment for under-resourced HR teams.
  • Award-winning Support Heroes cited frequently in reviews — responsive human support after implementation is a differentiator.

Object mapping

How EPAY HCM objects map to BambooHR

Each row shows how a EPAY HCM 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.

EPAY HCM

Employee

maps to

BambooHR

Employee

1:1
Fully supported

EPAY Employee records (personal info, employment history, job titles, departments, locations, hire dates, termination dates) map directly to BambooHR Employee. We use BambooHR's GET /v1/employees/directory endpoint for the initial export and resolve custom fields via GET /v1/meta/fields per the BambooHR field-request model. BambooHR does not paginate the employee list — all employees return in a single response, so large workforces require chunked processing in the transformation layer. Employment status (active, inactive, terminated) maps from EPAY's employmentHistoryStatus to BambooHR's status field.

EPAY HCM

Compensation Records

maps to

BambooHR

Pay Rate fields

1:1
Fully supported

EPAY's pay rate, salary history, pay frequency, bonus payments, and effective-dated compensation changes map to BambooHR's payRate, payType, payPeriod, and effectiveDate fields. BambooHR supports one active compensation record at a time per employee; we handle EPAY's historical compensation timeline by creating a sequence of compensation records with effectiveDate stamps during the migration. Bonuses and one-time payments migrate as separate entries in BambooHR's payRate where the payType indicates bonus or supplemental pay. Note that BambooHR does not support complex multi-component compensation structures (such as market-indexed pay or graduated commission tiers) in native fields.

EPAY HCM

Benefits Enrollments

maps to

BambooHR

Benefits

1:1
Mapping required

EPAY benefit plan assignments, coverage tiers, enrollment dates, and dependent information map to BambooHR's Benefits module. Plan names, carrier information, and coverage level (employee, employee-plus-spouse, family) migrate as structured benefit records. However, many insurance carriers require employees to re-enroll directly through the carrier portal or BambooHR's carrier integration after migration. We export the full enrollment dataset as supporting documentation and map it to BambooHR's benefits module, but advise budgeting for a two-to-four week parallel re-enrollment window with each benefits vendor before the first BambooHR payroll run.

EPAY HCM

Time and Attendance Logs

maps to

BambooHR

Time Off policies and requests

lossy
Mapping required

EPAY's clock-in/clock-out data, overtime records, accrual balances, and scheduling rules represent a data volume that BambooHR does not natively store or display. We map active accrual balances (PTO, sick leave, holiday hours) to BambooHR Time Off policies as opening balances, enabling employees to continue using accrued time after cutover. Historical punch-level data (clock events, break times, overtime hours) does not have a destination equivalent in BambooHR and is exported as a CSV archive for the customer's records. Scheduling rules and shift configurations do not migrate; we document the active schedule structures for the customer's admin to reconfigure in BambooHR's scheduling module or a dedicated scheduling tool.

EPAY HCM

Job Costing and Labor Allocation

maps to

BambooHR

Not supported

1:1
Mapping required

EPAY job costing features (cost center assignments, project code allocations, department-level labor budgeting) have no native equivalent in BambooHR's object model. We export the active cost center and project code assignments per employee as a reference CSV, map them to a custom multi-select picklist field in BambooHR (configured during migration), and flag that BambooHR does not support labor allocation reporting or job costing rollups. Customers relying on EPAY's job costing for billing, project tracking, or cost accounting must retain access to EPAY's reporting for these functions or implement a third-party labor allocation tool post-migration.

EPAY HCM

Payroll Processing History

maps to

BambooHR

Not supported as historical record

lossy
Mapping required

EPAY payroll run records (earnings, deductions, taxes, net pay by pay period) do not migrate into BambooHR as historical payroll records because BambooHR stores payroll data differently depending on the tier and does not maintain a full payroll run history accessible as an importable object. We export the most recent twelve months of payroll summaries per employee as a structured CSV archive and map year-to-date earnings and tax withholding totals to BambooHR's payRate and custom year-to-date fields for payroll processing continuity. Tax filing history and historical W-2 data remain in EPAY for lookback purposes.

EPAY HCM

Garnishments and Deductions

maps to

BambooHR

Not supported

lossy
Mapping required

EPAY court-ordered garnishments, wage deductions, and voluntary deduction codes with current balances have no BambooHR equivalent object. Active garnishment orders require manual re-entry in BambooHR's payroll module (if payroll is subscribed) or in the customer's payroll provider's system before the first post-migration payroll run. We export the current deduction codes, deduction types, percentage or fixed amounts, and remaining balances as a structured handoff document. This is one of the highest-risk migration items: missed or incorrectly entered garnishments can result in legal liability for the employer.

EPAY HCM

Performance Review Records

maps to

BambooHR

Performance Reviews

1:1
Mapping required

EPAY performance review cycles, 360-degree feedback, journaling entries, and review status tracking map to BambooHR's Performance Reviews module. Review dates, overall scores, status (draft, submitted, approved), and reviewer names migrate directly. Written feedback content migrates as text fields attached to the review record. Note that BambooHR's review cycle structure (annual, semi-annual, custom) may differ from EPAY's; we map the source review frequency to the closest BambooHR equivalent and flag any review templates requiring manual reconstruction.

EPAY HCM

Learning and Training Records

maps to

BambooHR

Limited support

1:1
Mapping required

EPAY course completion records, custom certificates, and training status map to BambooHR where the training module is available on the subscribed tier. Completion dates, course names, and certificate metadata migrate as training entries. BambooHR's training module supports course tracking and completion records but does not replicate complex custom course structures or curriculum sequences from EPAY. We export the full training history as a CSV archive and map what the BambooHR training module can consume; the customer's HR admin rebuilds curriculum structures in BambooHR if needed.

EPAY HCM

ACA Compliance Data

maps to

BambooHR

Not supported

lossy
Mapping required

EPAY ACA measurement data, coverage offer records, and enrollment status for Affordable Care Act compliance have no native equivalent in BambooHR. We export the current ACA measurement period data, eligibility status, and coverage offer history as a compliance archive. The customer's HR team or legal counsel must determine how to maintain ACA compliance documentation post-migration, which may involve a separate ACA tracking tool or retaining EPAY access for compliance lookback during the measurement period.

EPAY HCM

Employee Files and Documents

maps to

BambooHR

Employee Files

1:1
Fully supported

EPAY stored employee documents (offer letters, contracts, signed agreements, identification copies) migrate as BambooHR Employee Files attached to the corresponding employee record via the BambooHR Files API. We resolve file attachments by employee ID match and map the document type (I-9, W-4, offer letter, etc.) to the BambooHR file category. BambooHR's file storage limits apply per the subscribed plan; we verify storage availability before importing large document volumes.

Pair-specific challenges

  • EPAY has no public API — extraction is vendor-assisted

    EPAY HCM does not publish a REST or bulk API for customer data extraction. All migration exports require coordination with EPAY's internal export tooling and are gated on their availability. This adds timeline risk because the export format, record count, and delivery timing depend on EPAY's team rather than our automation. We request exports early in the scoping phase and validate record counts before beginning transformation work. Customers should expect the export coordination window to add one to two weeks to the project schedule compared to migrations from platforms with open APIs.

  • Active garnishment and deduction orders require manual re-entry

    EPAY garnishment orders (child support, tax levies, student loan garnishments, creditor wage garnishment) and active voluntary deduction codes have no equivalent in BambooHR's data model. We export the current deduction configuration as a structured handoff document, but BambooHR does not have a garnishments or deductions object to receive this data programmatically. The customer's payroll team must manually re-enter every active garnishment order in BambooHR before processing the first payroll run. Failure to re-enter garnishments correctly creates legal exposure for the employer.

  • Benefits carrier re-enrollment is required after migration

    Although we export EPAY benefit enrollment records with plan names, carriers, coverage tiers, and enrollment dates, many insurance carriers require employees to re-enroll directly through the carrier portal or BambooHR's benefits carrier integration. We map the enrollment data to BambooHR as supporting documentation, but the employee-facing re-enrollment step must happen within a two-to-four-week window coordinated with each benefits vendor. Employers should plan this window before their first BambooHR payroll run to avoid coverage gaps.

  • Job costing and labor allocation have no BambooHR equivalent

    EPAY customers using job costing and labor allocation features (cost centers, project codes, department budgets) will not find a native equivalent in BambooHR. We export active cost center and project assignments as a custom field in BambooHR, but BambooHR does not roll up labor costs by project or track labor allocation against budgets. Customers relying on EPAY's job costing for billing or project accounting must retain EPAY reporting access for these functions or implement a separate labor tracking tool.

  • BambooHR rate limits require chunked import processing

    BambooHR enforces approximately 100 requests per minute per API key with no published rate-limit headers. Exceeding the limit returns a 503 Service Unavailable response (not the standard 429 status). We implement exponential backoff on 503 responses and chunk all employee imports into batches sized to stay within the effective limit. For migrations exceeding 500 employees, the import phase may require additional days due to rate-limit accommodation.

Migration approach

Six steps for a successful EPAY HCM to BambooHR data migration

  1. Scoping and EPAY export coordination

    We audit the EPAY source environment: employee headcount (active, inactive, terminated), compensation history periods, active benefits enrollments, active garnishment orders, time-off accrual balances, and any custom fields or objects in use. Because EPAY has no public API, we submit a formal export request to EPAY's customer success team and agree on a delivery timeline. We validate the export record counts against our scoping estimates before accepting the export file. If the export is delayed, the project timeline extends accordingly.

  2. BambooHR destination setup and schema preparation

    We configure the BambooHR destination: create custom fields for EPAY custom properties (cost center assignments, year-to-date payroll totals, original hire source), set up Time Off policies with opening balances migrated from EPAY accrual records, configure the Benefits module with the customer's carrier integrations, and enable the Performance Reviews module if the customer subscribes to that tier. We use the BambooHR API (GET /v1/meta/fields) to enumerate all available and custom fields before mapping.

  3. Transformation and compensation timeline construction

    We transform EPAY exports into BambooHR-compatible format. The highest-complexity transform is the compensation timeline: EPAY stores multiple effective-dated compensation changes per employee; BambooHR supports one active compensation record at a time. We create a sequenced compensation history with effectiveDate stamps and separate bonus/payType entries. We split employee records into active and inactive, apply the status mapping (terminated employees with terminationDate become inactive in BambooHR), and resolve any duplicate email addresses that would cause import conflicts.

  4. Garnishment and deduction handoff preparation

    We compile every active garnishment order and voluntary deduction code into a structured handoff document with employee name, deduction type, amount or percentage, start date, and current balance. This document is reviewed by the customer's payroll team before cutover. We do not import garnishments into BambooHR because no import path exists; the document serves as the payroll team's manual re-entry checklist. We flag the cutover date by which all garnishments must be re-entered to avoid a missed payroll.

  5. Staged import and validation

    We run a staged import into the customer's BambooHR environment in dependency order: Employees first (with status and custom fields), then Compensation (with effectiveDate sequenced), then Benefits (as enrollment records), then Time Off policies (with accrual opening balances), then Performance Reviews, then Employee Files. Each phase emits a row-count reconciliation report. We validate 25 to 50 spot-check records against the EPAY source for field-level accuracy. Any mapping corrections are applied before the next phase begins.

  6. Cutover, delta sync, and manual handoff

    We freeze EPAY writes during cutover, run a final delta migration of any records modified during the migration window (new hires, compensation changes, terminations), then declare BambooHR the system of record. We deliver the garnishment handoff document, the job costing reference CSV, the ACA compliance archive, and the training history export to the customer's HR and payroll teams. We do not rebuild EPAY workflows, scheduling rules, or time-tracking configurations in BambooHR; these are documented separately for the customer's admin to reconstruct or to evaluate as separate implementation projects.

Source

Strengths

  • All-in-one bundling of recruiting, onboarding, HR, benefits, time tracking, and payroll under a single vendor relationship reduces multi-vendor coordination overhead.
  • Fixed per-employee pricing model provides predictable monthly costs with no surprise transaction fees, unlimited admin seats, and included tax filing across all jurisdictions.
  • FedRAMP Ready certification for time and labor management meets federal cloud security standards required by government contractors and public-sector employers.
  • Complex workforce handling for multi-state, multi-union, and split-shift environments is a documented differentiator, with customers in construction, staffing, and manufacturing specifically citing flexibility.
  • 24/7 customer support included at no extra charge with a dedicated Client Relationship Manager assigned at onboarding.

Weaknesses

  • No public pricing page or tier documentation — prospects must request a quote, making budget planning and vendor comparison difficult before committing.
  • No documented public API for programmatic data export — integrations and migrations rely on vendor-assisted exports or manual data extraction, limiting automation options.
  • Reporting and analytics capabilities are described as functional but not deep, with customers noting they supplement EPAY analytics with external BI tools for workforce insights.
  • Switching away requires coordinating a full-suite migration since the platform bundles multiple HCM functions — there is no modular exit path for individual modules.
  • Steep administrative configuration curve for complex pay rules, union agreements, and multi-state tax setups extends implementation timelines beyond initial estimates.

BambooHR

Destination

Strengths

  • Single platform consolidating ATS, onboarding, HR records, payroll, and time-off reduces system sprawl for SMBs.
  • Fast implementation — BambooHR reports four to six weeks from kickoff to go-live for most customers.
  • Per-employee pricing with automatic volume discounts makes cost predictable as headcount grows.
  • Strong customer support reputation (Support Heroes) cited consistently across G2, Capterra, and direct testimonials.
  • Well-documented API with UTF-8 encoding, clear field types, and HTTPS-only access.

Weaknesses

  • Mobile application is significantly limited compared to the desktop experience, frustrating remote and field workers.
  • Companies above 150–200 employees frequently outgrow the platform's feature depth and customization surface.
  • Limited advanced reporting and analytics compared to enterprise HR platforms — custom report building is the ceiling.
  • PTO and profile customization are pain points — non-standard accrual policies and complex org structures require workarounds.
  • Document management and attachment handling lack the granularity of dedicated document-centric HR systems.

Straightforward migrations under 200 employees with current employment data and basic benefits enrollments complete in three to five weeks. Migrations with large historical compensation timelines (more than 24 months of rate-change records), active garnishment orders, or multiple benefits carriers requiring re-enrollment extend to seven to eleven weeks. The primary timeline variable is the vendor-assisted export coordination with EPAY, which can add one to two weeks to scoping if EPAY's export team has scheduling delays.
