Overview

What this migration involves

Migrating from EBMS to Epicor ERP is a structured extraction-and-load project shaped by EBMS having no documented public REST API. All source data must be extracted through the built-in report writer, extended to include any custom fields before extraction, and delivered as structured CSV or Excel for Epicor DMT ingestion. Epicor ERP organizes manufacturing data around Part, Supplier, Customer, OrderHed, and POHeader records with separate PartPlant and OrderDtl detail records. We map EBMS Customers to Epicor Customer, EBMS Inventory Items to Part and PartPlant, EBMS Sales Orders to OrderHed and OrderDtl, EBMS Purchase Orders to POHeader and PODetail, and EBMS Vendors to Supplier. Custom fields built in EBMS Customization Designer require database-level enumeration before we can map them. We do not migrate EBMS Reports, automation configurations, or eCommerce website configurations; these are documented in an inventory the customer's admin uses to rebuild in Epicor.

Why teams make this switch

Two sides of the same decision

Leaving

EBMS logo

EBMS

What's pushing teams away

  • EBMS is a Windows desktop application requiring on-premise or terminal server infrastructure, which conflicts with cloud-first IT strategies.
  • Limited public API and integration capabilities make real-time sync with modern SaaS tools difficult to maintain.
  • The user interface and workflow design reflect older ERP paradigms, creating friction for teams accustomed to modern UX conventions.
  • Support subscription costs add ongoing expense, and discontinuing it cuts access to tax table updates and software patches — a hard cliff for compliance-dependent businesses.
  • eCommerce tiers cap annual online sales volumes, forcing upgrades as the business grows rather than scaling smoothly.

Choosing

Epicor Prophet 21 logo

Epicor Prophet 21

What's pulling them in

  • Industry-specific design for wholesale distributors, not a general-purpose ERP repurposed for distribution — distributors choose P21 because it matches their replenishment, kitting, and counter-sale workflows out of the box.
  • Strong inventory control with automated replenishment, lot and serial tracking, and multi-warehouse management appeals to distributors with complex stock requirements and tight margin pressure.
  • Responsive customer support cited across G2 and Gartner reviews, with Epicor's 90% retention rate reflecting long-term customer satisfaction in a market where switching costs are high.
  • Cloud deployment on Microsoft Azure provides the flexibility to scale user counts and warehouse locations without on-premise infrastructure investment.
  • The Software Development Kit lets distributors personalize P21 to their specific business processes without modifying the application source code, preserving upgrade paths.

Object mapping

How EBMS objects map to Epicor Prophet 21

Each row shows how a EBMS object lands in Epicor Prophet 21, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

EBMS

Customer

maps to

Epicor Prophet 21

Customer

1:1
Fully supported

EBMS Customer records map to Epicor Customer with the CustomerID as the dedupe key. Standard EBMS fields (name, address, terms, ship-to locations) map to Epicor Customer base fields. EBMS customer price levels map to Epicor Customer Price Group assignments on the Customer record or to individual CustomerPart Xref records if the customer has negotiated per-part pricing. We resolve the CustomerID from EBMS using the customer code field and validate uniqueness before insert. EBMS Customer Portal accounts map to Epicor Customer with the portal price level stored in a custom field or as a Customer Price Group assignment.

EBMS

Inventory Item / Product

maps to

Epicor Prophet 21

Part + PartPlant

1:1
Fully supported

EBMS inventory items map to Epicor Part records. EBMS product fields (description, unit of measure, standard cost, stocking quantity) map to Epicor Part (PartNum, PartDescription,IUM) and PartPlant (OnHandQty, LeadTime, ABCCode). Serial number tracking in EBMS maps to Part.SalesUM and PartStock.SerialNumber if the Epicor environment is configured for serial tracking. EBMS product pricing tiers (price levels 1-99) map to Epicor PriceLbr records or to Part.SalesUM pricing if simplified. EBMS product categories map to Epicor Product Group codes. We request PartPlant configuration (site-specific stocking and planning data) to be exported separately from the base Part master.

EBMS

Sales Order

maps to

Epicor Prophet 21

OrderHed + OrderDtl

1:1
Fully supported

EBMS Sales Order headers map to Epicor OrderHed with OrderNum as the parent key. EBMS order line items map to OrderDtl with Line, PartNum, OrderQty, UnitPrice, and Discount fields preserved. EBMS payment terms on the order header map to OrderHed.TermsCode. EBMS order status (open, shipped, invoiced, closed) maps to Epicor OrderHed.OpenLine and OrderHed shipped/released flags. We extract OrderHed and OrderDtl via separate EBMS reports and merge them during transform so that the parent-child relationship is resolved at import time. Historical closed orders require careful date-range scoping; we confirm whether the customer wants full history or only open and recent orders.

EBMS

Sales Order Pipeline / Stage

maps to

Epicor Prophet 21

OrderHed.Status + OrderHed.TermsCode

lossy
Fully supported

EBMS does not have an explicit pipeline or deal-stage model; orders progress through document statuses (Quote, Order, Shipped, Invoiced, Closed). Epicor OrderHed has a Status field that maps to these document states. We configure Epicor OrderHed.Status values to match the EBMS order lifecycle during migration. EBMS quote extensions (quotes not yet converted to orders) map to Epicor QuoteHed if the customer uses Epicor CPQ, or to OrderHed with a Quote-held status if CPQ is not licensed.

EBMS

Purchase Order

maps to

Epicor Prophet 21

POHeader + PODetail

1:1
Fully supported

EBMS Purchase Order headers map to Epicor POHeader with PONum as the parent key. EBMS PO line items map to PODetail with POLine, PartNum, POLine.UnitCost, OrderQty, and DueDate preserved. EBMS vendor references on PO map to POHeader.SupplierID via the Vendor mapping. EBMS PO approval status maps to POHeader.Status. We extract POHeader and PODetail via separate EBMS reports and merge them before Epicor DMT import. EBMS custom fields on PO headers or lines require explicit mapping to Epicor UD fields on POHeader or PODetail.

EBMS

Invoice / Accounts Receivable

maps to

Epicor Prophet 21

InvoiceHed + InvoiceDtl

1:1
Fully supported

EBMS invoices map to Epicor InvoiceHed and InvoiceDtl. EBMS invoice header fields (invoice number, date, customer, terms, total) map to Epicor InvoiceHed fields. EBMS invoice line items map to InvoiceDtl with PartNum, InvoiceQty, UnitPrice, and ExtendedPrice. EBMS open AR aging data maps to Epicor CashReceipt if partial payments have been recorded. Historical invoice PDFs are exported as files and attached to Epicor InvoiceHed via DocumentRev records. We scope historical invoices by date range to avoid mid-period splits and confirm with the customer whether the new Epicor environment will carry the full AR history or only open items.

EBMS

Vendor

maps to

Epicor Prophet 21

Supplier

1:1
Fully supported

EBMS Vendor records map to Epicor Supplier with SupplierID as the dedupe key. EBMS vendor fields (name, address, payment terms, contacts) map to Epicor Supplier base fields. EBMS vendor part numbers for purchased items map to Epicor SupplierPart Xref records for cross-referencing. EBMS vendor-specific pricing tiers map to Epicor SupplierPrice effective-date records. We extract vendors via EBMS vendor reports and map them to Supplier before PO import to satisfy the SupplierID lookup on POHeader.

EBMS

Custom Fields (Customization Designer)

maps to

Epicor Prophet 21

UD Fields (PartUims, VendorUims, etc.)

1:many
Fully supported

EBMS custom fields created in the Customization Designer may exist on any entity (Customer, Product, Order, PO, Vendor). These are not always visible in standard EBMS reports without first adding them to the report layout. We request read-only SQL access during data profiling to enumerate all custom field columns in the EBMS database, then work with the customer to confirm which custom fields require migration. Each EBMS custom field maps to a corresponding Epicor UD field (e.g., PartUOM.Character01 for string UD fields, Customer.UDFld1 for customer custom fields). We pre-create Epicor UD fields in the destination environment before data import begins. Fields without an Epicor destination are flagged in the mapping document for the admin to resolve.

EBMS

eCommerce Product Catalog

maps to

Epicor Prophet 21

Part + PartWebConf

1:1
Fully supported

EBMS eCommerce product data (product name, description, images, availability, pricing, categories) maps to Epicor Part and PartWebConf (web configuration) records if the customer licenses Epicor Commerce or integrates with a third-party commerce platform. EBMS product catalog exports via inventory reports include web-specific fields (web description, image URLs, category assignments) that map to PartWebConf and CategoryPart records in Epicor. EBMS eCommerce tier caps do not affect the migration scope directly, but we confirm whether the customer has been capping or manually handling orders at the tier boundary, which could result in incomplete order history.

EBMS

Customer Portal Accounts

maps to

Epicor Prophet 21

Customer + CustomerPriceLbr

1:1
Mapping required

EBMS Customer Portal accounts store B2B customer login credentials, price levels, and payment terms. These map to Epicor Customer records with the portal price level stored in CustomerPriceLbr or a custom field on Customer. EBMS portal-specific fields (price level visibility, credit limit override) map to Epicor CustomerCreditLimit and Customer.PriceCode. We extract portal accounts from EBMS customer reports and map them as a supplement to the standard Customer migration, with the portal-specific fields stored in designated Epicor custom fields.

EBMS

GL Accounts

maps to

Epicor Prophet 21

GLAccount

1:1
Fully supported

EBMS general ledger account codes and descriptions map to Epicor GLAccount with AccountDesc preserved. EBMS account segments (if using segmented chart of accounts) map to Epicor GLAccount with COACode and segments parsed from the EBMS account code. We extract GL accounts via EBMS financial reports and map them before invoice and PO import so that distribution accounts are resolved at load time. Cross-reference mapping from EBMS account codes to Epicor GLAccount numbers is delivered as a written mapping table for the customer's GL team to validate.

EBMS

Salespersons / Sales Representatives

maps to

Epicor Prophet 21

SalesRep

1:1
Fully supported

EBMS salesperson records map to Epicor SalesRep with SalesRepCode as the dedupe key. EBMS salesperson names, commission rates, and territories map to Epicor SalesRep fields. Salesperson assignments on EBMS orders map to OrderHed.SalesRepCode via the SalesRep mapping during order import. We extract salespersons via EBMS user and sales reports and validate against Epicor SalesRep records before importing orders.

Pair-specific challenges

  • EBMS has no REST API — all extraction via report writer

    EBMS provides no documented public REST or bulk API. All data extraction proceeds through the built-in report writer and CSV or Excel export. This means we cannot initiate API calls to pull records in bulk, delta-sync changes, or query custom fields directly. We must scope all exports upfront via the report writer, and any custom fields not yet added to a report must be added before extraction begins. We coordinate with the customer to identify all relevant EBMS reports, extend them with missing custom fields, and confirm the export schedule before the migration window opens.

  • Custom fields require database access to enumerate fully

    The EBMS Customization Designer allows business users to add custom fields to any document, but these fields are not always visible in the standard report writer without first adding them to the report layout. Developer-created custom fields whose definitions cannot be edited in the UI require exclusive read-only SQL database access to discover. We request read-only SQL access during data profiling to enumerate all custom field columns before building the export maps. Without this step, custom fields are discovered only when records with non-standard columns appear in the report export, causing mapping rework mid-project.

  • Epicor DMT does not support all EBMS entity structures natively

    Epicor DMT ships with over 60 pre-built import templates for common Epicor entities, but EBMS document structures (particularly custom fields, multi-segment PO line structures, and eCommerce-specific fields) do not always align with a DMT template. We build custom CSV transforms that map EBMS export columns to Epicor DMT template columns, with custom field mappings handled as UD field imports that run after the base entity templates. We validate the transform logic in Epicor Sandbox before running in production.

  • Epicor Prophet 21 and Kinetic are different products with different schemas

    EBMS and Epicor Prophet 21 share some functional overlap as SMB-focused ERPs from the ECi portfolio, but Epicor Kinetic (the cloud ERP platform) is a separate product line with a distinct data model. If the customer is migrating from EBMS and considering Prophet 21 or Kinetic as the destination, we clarify the schema differences during discovery. For Kinetic specifically, Part, Customer, and Order structures use the Kinetic data model (e.g., PartNum replaces PartID, OrderHed replaces SOHeader). We do not assume schema parity with ECi products and build the mapping from EBMS to the specific Epicor destination.

  • Historical invoice and AR data may require closing balance scoping

    EBMS tracks open and historical invoices with full payment history. Migrating the complete AR aging and payment history into Epicor InvoiceHed and CashReceipt requires careful date-range scoping to avoid mid-period data splits. We recommend migrating only open invoices and a configurable lookback period (typically 12-24 months) for historical invoices, with the pre-migration AR closing balance recorded as an Epicor beginning balance entry rather than individual historical invoice records. This approach avoids data volume inflation in Epicor and reduces DMT import time.

Migration approach

Six steps for a successful EBMS to Epicor Prophet 21 data migration

  1. Discovery and EBMS report audit

    We conduct a discovery phase that includes auditing every EBMS report used for data extraction, identifying all standard and custom fields used on Customers, Products, Sales Orders, Purchase Orders, Vendors, and Invoices, and requesting read-only SQL access to enumerate custom fields not visible in the report writer. We deliver a written extraction plan that lists each EBMS report to be run, the fields to be added to each report before export, and the file format (CSV or Excel) for each entity. We also confirm the customer's Epicor edition (Kinetic SaaS or on-premise), licensed modules, and any existing Epicor configuration (COA structure, site assignments, currency settings) that affects the destination schema design.

  2. Epicor DMT template configuration and UD field pre-creation

    We configure Epicor DMT templates for each entity type in scope (Customer, Part, PartPlant, POHeader, PODetail, OrderHed, OrderDtl, Supplier, InvoiceHed, InvoiceDtl, GLAccount, SalesRep). For each DMT template, we map the EBMS export columns to the corresponding Epicor DMT column names. Custom EBMS fields map to Epicor UD fields (PartUOM, VendorUOM, CustomerUDF fields, etc.) which we pre-create in the destination Epicor environment via Epicor Ice.Library.UpdateUDColumn or a BAQ-generated UD field definition. UD field creation is validated in Epicor Sandbox before production deployment.

  3. EBMS data extraction with custom field inclusion

    We guide the customer's EBMS administrator through running each scoped report, verifying that all custom fields are included in the report layout before export. Custom fields not yet in any report are added to the relevant report via the Customization Designer before extraction. We receive the exported CSV or Excel files and perform a data profiling pass that checks record counts, identifies missing required fields for Epicor DMT (e.g., CustomerID, SupplierID, PartNum), flags duplicate records, and validates date ranges for historical scoping. We report any data quality issues back to the customer for remediation before transformation begins.

  4. Data transformation and Sandbox migration

    We transform EBMS export files into Epicor DMT-ready CSV format, applying the column mapping, custom field translation, and deduplication logic designed in step two. We run the DMT import into a full-copy or partial-copy Epicor Sandbox using production-like data volume. The customer's Epicor administrator reconciles record counts (Customers in, Parts in, Orders in, POs in, Invoices in), spot-checks 25-50 records against the EBMS source for field-level accuracy, and validates that custom fields populated correctly on the UD field records. Any mapping corrections are made to the transform logic and the Sandbox migration is re-run before production migration begins.

  5. Owner and cross-reference reconciliation

    Epicor requires valid references for SupplierID on POHeader, CustomerID on OrderHed, PartNum on OrderDtl, and SalesRepCode on OrderHed. We build a cross-reference table that maps EBMS vendor codes to Epicor SupplierID, EBMS customer codes to Epicor CustomerID, EBMS product codes to Epicor PartNum, and EBMS salesperson codes to Epicor SalesRepCode. Any EBMS records with unmapped references go to a reconciliation queue for the customer to resolve before the production migration phase. We cannot insert an OrderHed without a valid CustomerID; resolution is required before insert.

  6. Production migration in dependency order and cutover

    We run production migration in Epicor in dependency order: GLAccount and SalesRep (reference data, no dependencies), Supplier (required for POHeader), Customer (required for OrderHed and InvoiceHed), Part and PartPlant (required for OrderDtl and PODetail), POHeader and PODetail, OrderHed and OrderDtl, InvoiceHed and InvoiceDtl, and finally custom field UD imports. Each phase emits a row-count reconciliation report before the next phase begins. We freeze EBMS writes during the cutover window, run a final delta migration of any records modified during the migration window, then enable Epicor as the system of record. We deliver a written inventory of EBMS Reports, eCommerce configurations, and automation settings that do not migrate and must be rebuilt in Epicor by the customer's admin team or implementation partner.

Platform deep dives

Context on both ends of the pair

EBMS logo

EBMS

Source

Strengths

  • Unified data model across sales, inventory, accounting, and eCommerce eliminates reconciliation between systems.
  • Customization Designer gives business users control over field extensions without developer intervention.
  • Report-based export framework produces structured output for most core entities.
  • Integrated B2B customer portal with price-level visibility and payment-term enforcement.
  • Healthcare and pharmacy-specific modules available for benefit management and prescription solutions.

Weaknesses

  • No documented public REST API — all integration and migration relies on report exports and CSV files.
  • Windows desktop architecture limits deployment flexibility and remote access compared to cloud-native ERPs.
  • eCommerce module tiers impose annual sales volume caps that trigger forced upgrades.
  • Custom fields created in the database require exclusive access to enumerate fully, complicating data profiling.
  • Support discontinuation within six months resets onboarding to new-client terms at current SaaS rates.

Destination

Strengths

  • Purpose-built for wholesale distribution with industry-specific replenishment, kitting, and counter-sale workflows out of the box.
  • Multi-warehouse management with bin locations, cross-docking, and real-time inventory visibility across all warehouse locations.
  • Automated replenishment engine with demand-based and min-max planning reduces stockouts and overstock carrying costs.
  • AI-infused reporting via Epicor Prism provides Gen AI-driven insights into ERP data without requiring a BI team.
  • Strong customer retention at 90% and a 50-year track record in the distribution vertical provides long-term vendor stability.

Weaknesses

  • High total cost of ownership — per-user pricing of $150-200/month plus $10K-$500K implementation creates significant budget commitment for small and mid-market distributors.
  • Customization via SDK requires technical expertise and introduces upgrade risk when custom code conflicts with new P21 releases.
  • Report generation performance is a known pain point — multiple users report system freezes during large or complex report exports.
  • Third-party bolt-on reliance for functionality that competitors include natively increases integration complexity and total solution cost.
  • Limited public API documentation — developers building custom integrations report difficulty finding P21 API authentication methods and endpoint specifications.
