Overview
Moving from Selly ERP to Epicor ERP is a structural migration from a small-business CRM-plus-light-ERP platform to a purpose-built manufacturing and distribution ERP for companies with 50-2,500 employees. Selly ERP has no publicly documented API, which means every export begins with a manual in-app data dump per module; we design the export schedule with the customer during discovery and validate each CSV before ingestion. Epicor Kinetic uses a REST API for data ingestion with BAQ-based reporting and BPM-based customisation, which is fundamentally different from Selly's configuration model. We map Selly's Customers to Epicor Customer records, Deals to Sales Orders and Quotes, Pipeline Stages to Order and Quote stages, Parts to Epicor Part records with UOM and BOM data, and Activities to Document records. Workflow automations, invoice PDFs, and custom configuration do not migrate; we deliver a written inventory of active Selly automations and an Epicor BPM rebuild guide for the customer's admin team.

Object mapping
Each row shows how a Selly Erp 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.
Selly Erp
Lead
Epicor Prophet 21
Prospect
1:1Selly ERP Leads map to Epicor Kinetic Prospect records. The Prospect table (UD08) stores pre-customer prospects with fields for company name, contact name, email, phone, and source. We carry over lead source and any custom fields as UD columns on Prospect. The Epicor Kinetic REST API endpoint /api/v1/Prospect handles ingest. Prospects without a company association store contact details in the ShipTo address fields.
Selly Erp
Customer
Epicor Prophet 21
Customer
1:1Selly ERP Customer records map directly to Epicor Kinetic Customer records in the Customer table (Customer table, not a CRM contact object). Fields mapped include Company, CustID, Name, Address, City, State, Country, PostalCode, PhoneNum, EmailAddress, and TerritoryID. We preserve the Selly billing address as the primary Customer address and any shipping addresses as ShipTo records linked by CustNum. Epicor Kinetic supports multiple ShipTo records per Customer, which covers customers with multiple delivery locations.
Selly Erp
Opportunity
Epicor Prophet 21
Quote
1:1Selly ERP Opportunities with an estimated value and close date map to Epicor Kinetic Quote records. The Quote header stores the customer reference, order total, and stage. Epicor Kinetic uses QuoteNum as the primary key and stores line items (PartNum, SellingQuantity, UnitPrice, DiscountPercent) in QuoteDtl. We map the Selly pipeline stage name to the Epicor Quote.QuoteStatus field and carry over the estimated value as the Quote.DocTotal field. Open quotes migrate as active Epicor quotes; closed-won quotes migrate as historical records or convert to Sales Orders if the customer chooses.
Selly Erp
Deal
Epicor Prophet 21
Sales Order
1:1Selly ERP Deals that have reached a closed-won state map to Epicor Kinetic Sales Orders. We create OrderHed records with CustomerNum, OrderNum, PONumber, and OrderDate, then create OrderDtl line items from the deal line items with PartNum, Quantity, UnitPrice, and Discount. The Selly deal owner becomes the Epicor BuyerID on the OrderHed. OrderRel (fulfilment release) records are created for each line item based on the requested delivery date.
Selly Erp
Pipeline Stage
Epicor Prophet 21
Quote Stage or Order Type
lossySelly ERP pipeline stage names (Prospecting, Qualification, Proposal, Negotiation, Closed Won, Closed Lost) map to Epicor Kinetic Quote.QuoteStatus values or a custom Quote Stage UD column if the customer uses Epicor's stage tracking. We extract the full Selly pipeline stage list during scoping, confirm the mapping with the customer, and configure the matching Quote status values in Epicor before migration begins. Stage probability percentages are stored as UD fields on the Quote.
Selly Erp
Product
Epicor Prophet 21
Part
1:1Selly ERP Products map to Epicor Kinetic Part records. The Part table stores PartNum, PartDescription, UnitOfMeasure, TypeCode (stocked, make-to-order, phantom), and CostData. The Selly SKU maps to Part.PartNum, and any Selly product categories map to Part.ClassID or a UD field. Standard cost from Selly migrates as Part.StandardCost. We create PartPlant records for each Epicor site where the part is stocked.
Selly Erp
Quote Line Item
Epicor Prophet 21
QuoteDtl
1:1Selly ERP Quote line items map to Epicor Kinetic QuoteDtl records. Each line carries the PartNum (or a description-only line), SellingQuantity, UnitPrice, DiscountPercent, and a reference to the parent QuoteNum. QuoteDtl.DocUnitPrice preserves the original quoted price. If Selly stores pricing by volume break, we create multiple QuoteDtl lines or use Epicor's Quantity Price Break functionality.
Selly Erp
Invoice
Epicor Prophet 21
AR Invoice (historical)
1:1Selly ERP Invoices cannot be migrated as structured Epicor ERP transactional records because Selly does not export invoice PDFs as structured data reliably. We archive the invoice PDF files separately and link them to the corresponding Epicor Customer record as a document attachment. The invoice line items (PartNum, Quantity, UnitPrice) are re-imported as structured records manually or via a separate line-item import batch. Customers requiring full invoice history in Epicor should plan for a separate AR import using Epicor's AR Invoice entry or a bulk import tool.
Selly Erp
Activity
Epicor Prophet 21
Document and Notes
1:1Selly ERP Activities (calls, emails, meetings, tasks, notes) attached to Contacts, Companies, or Deals map to Epicor Kinetic Document records linked via the DocType and Key fields. Activity timestamps migrate as the Document.CreateDate and Document.CreateTime. Email body content stores as Document[1] character data. Meeting location and duration store as UD fields. We normalise timestamps to UTC before Epicor ingest. The activity owner maps to an Epicor User ID for assignment tracking.
Selly Erp
Custom Field
Epicor Prophet 21
UD Column (UD01-UD30)
lossySelly ERP custom fields on any object migrate to Epicor Kinetic User-Defined (UD) columns. Each Selly custom field is assessed for data type (string, number, date, boolean, picklist) and mapped to the corresponding Epicor UD data type (string, int, date, boolean, character). We pre-create UD columns in Epicor during the schema phase before any data import. Epicor Kinetic UD columns are created in the Ice.BO.UserFile tables (UD01, UD02, etc.) and linked to the base table via Key1, Key2, Key3 values. Epicor community posts confirm that UD column mapping requires BPM logic for calculated or conditional values.
Selly Erp
Owner/User
Epicor Prophet 21
User
1:1Selly ERP user accounts map to Epicor Kinetic User records. We resolve owners by email match against the Epicor Kinetic User table. Any Selly Owner without a matching Epicor User goes to a reconciliation queue for the customer's admin to provision before record import resumes. Inactive or archived Selly users are migrated as inactive Epicor User records for audit completeness.
Selly Erp
Attachment
Epicor Prophet 21
Document Management
1:1File attachments linked to Selly ERP records are extracted from the export and uploaded to Epicor Kinetic's Document Management system. We link documents to the parent record (Customer, Quote, Order, Part) using the DocumentKey fields. Document Type (PDF, image, spreadsheet) is preserved. Attachments that do not survive the bulk export cleanly are stored in a managed file share and linked manually post-migration.

Pair-specific challenges
Migration approach
Discovery and manual export scheduling
We audit the source Selly ERP account across all modules: Leads, Customers, Opportunities, Deals, Products, Quotes, Invoices, Activities, and any custom fields. Since Selly ERP has no public API, we work with the customer to schedule the manual in-app export for each module, provide export templates specifying the exact fields and format required, and set expectations for data validation before ingestion begins. We also identify BOM and routing data held outside the standard Selly schema and plan the reconstruction phase accordingly. The discovery output is a written migration scope, an export checklist, and a BOM reconstruction plan if applicable.
Epicor Kinetic schema design and UD column provisioning
We design the destination schema in Epicor Kinetic. This includes creating Part records with the correct TypeCode (stocked, make-to-order, phantom), PartPlant records per site, BOM structures for parts with multiple levels, Quote and Order record types, and UD columns for any Selly custom fields. We deploy schema changes into a Epicor Kinetic sandbox first for validation. UD columns are created in the appropriate UserFile tables with correct data types and linked to base tables via Key fields. Any UD columns requiring calculated values are flagged with BPM logic requirements for the customer's Epicor partner to implement.
Sandbox migration and reconciliation
We run a full migration into the Epicor Kinetic sandbox using production-like data volume. The customer's operations and finance leads reconcile record counts (Customers in, Quotes in, Orders in, Parts in, Activities in), spot-check 25-50 random records against the Selly source export, and sign off the schema and mapping before production migration begins. Any mapping corrections, missing UD columns, or BOM reconstruction issues surface here. Epicor Kinetic REST API rate limits and BAQ query performance are tested against the sandbox to calibrate batch sizes for production ingest.
Owner reconciliation and Epicor Kinetic User provisioning
We extract every distinct Selly ERP Owner referenced on any record and match by email against the Epicor Kinetic User table. Owners without a matching Epicor User go to a reconciliation queue. The customer's Epicor admin provisions any missing users (active or inactive depending on whether the original Selly user is still active). We also identify any Selly users who are assigned as record owners but do not have a corresponding Epicor login, as OwnerId references are required on most Epicor transactional records. Epicor Kinetic supports role-based access control, which we map from Selly's user tier structure.
Production migration in dependency order
We run production migration into Epicor Kinetic in record-dependency order using the REST API: Part records (base for all manufacturing and sales data), Customer records (base for quotes and orders), Prospect records, Quotes, Sales Orders, Activities, then UD column values. BOM structures are ingested after Parts are validated. We use Epicor Kinetic REST API batch endpoints with rate-limit handling and exponential backoff. Each phase emits a row-count reconciliation report before the next phase begins. Invoice PDFs are archived as document attachments and linked to the corresponding Customer records.
Cutover, validation, and automation rebuild handoff
We freeze Selly ERP writes during cutover, run a final delta migration of any records modified during the migration window, then enable Epicor ERP as the system of record. We deliver the Workflow and Automation inventory document with recommended Epicor BPM equivalents to the customer's Epicor implementation partner. We support a one-week hypercare window where we resolve any reconciliation issues raised by the customer's team. We do not rebuild Selly workflow automations as Epicor BPM inside the migration scope; that work is handled by the customer's Epicor partner as a separate engagement.
