Overview

What this migration involves

Moving from PeppyBooks to Epicor ERP is a structural migration from a small-business bundled accounting and CRM platform into a purpose-built mid-market manufacturing and distribution ERP. PeppyBooks stores Clients and Vendors as separate entity types, financial transactions linked to a customizable Chart of Accounts, and inventory as Products and SKUs available at Premium tier and above. Epicor ERP uses Part master records, Site and Warehouse entities, BOM hierarchies, and production scheduling that have no equivalent in PeppyBooks. We sequence the migration by exporting the PeppyBooks CoA first to establish GL account mapping, then migrate Customer and Vendor master records before open POs and SOs, then surface Part and inventory data, and finally load historical transaction history. PeppyBooks has no publicly documented REST API so we work from CSV exports and direct database access where available. Workflows, automations, and PeppyBooks CRM pipeline configurations do not migrate; we deliver a written inventory for the customer admin to rebuild in Epicor Kinetic.

Why teams make this switch

Two sides of the same decision

Leaving

PeppyBooks logo

PeppyBooks

What's pushing teams away

  • Customers outgrow the platform when they need multi-entity consolidation, advanced job costing, or ERP features like fixed-asset depreciation that PeppyBooks does not offer at any tier.
  • Lack of transparent public API documentation makes integrations with custom tools, e-commerce platforms, or payment processors difficult to maintain without developer assistance.
  • Pricing increases and tier-gated features force customers to upgrade as their business grows, and some report that essential features remain locked behind higher tiers even for legitimate operational needs.
  • Users with non-US tax requirements — particularly businesses with complex VAT reverse-charge scenarios or multi-state sales tax nexus — find PeppyBooks' tax compliance tools insufficient compared to purpose-built tax automation platforms.

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 PeppyBooks objects map to Epicor Prophet 21

Each row shows how a PeppyBooks 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.

PeppyBooks

Chart of Accounts

maps to

Epicor Prophet 21

GL Account

lossy
Fully supported

PeppyBooks maintains a hierarchical CoA with account codes, types, and tax-mapping attributes. Epicor ERP uses a segmented GL Account structure with Company, Division, Department, and Account segments. We export the full PeppyBooks CoA as a structured list, then create a segment-mapping configuration in Epicor that resolves each PeppyBooks account code to the appropriate Epicor account segment combination. If Epicor has a default CoA, we either merge source accounts into existing Epicor accounts or create new ones, preserving the PeppyBooks account name as a description label for accountant reconciliation.

PeppyBooks

Clients

maps to

Epicor Prophet 21

Customer

1:1
Fully supported

PeppyBooks Client records include contact details, billing address, payment terms, and opening balance. We map them 1:1 to Epicor Customer records, preserving the opening balance as an AR aging entry. PeppyBooks multi-currency support (Growth tier) maps to Epicor's currency configuration with exchange rate context carried forward. Customer payment terms migrate as Epicor Payment Terms linked to the Customer record.

PeppyBooks

Vendors

maps to

Epicor Prophet 21

Vendor

1:1
Fully supported

PeppyBooks Vendor master data mirrors Client structure with address, payment terms, and opening balance. We migrate Vendors to Epicor Vendor records, carrying forward any outstanding AP balances as AP aging entries. 1099 vendor classification from PeppyBooks maps to Epicor Vendor's tax configuration. Multi-currency vendor amounts migrate with their original exchange-rate context.

PeppyBooks

Invoices

maps to

Epicor Prophet 21

AR Invoice / Invoice

1:1
Fully supported

PeppyBooks generates invoices linked to Clients, line items, tax codes, and CoA revenue accounts. We export all invoice fields including status (draft, sent, paid), due dates, and payment records, then create Epicor AR Invoice records. PeppyBooks tax codes map to Epicor Tax Business Unit configuration. Historical paid invoices migrate as posted records with full line-item detail; open invoices migrate as open AR items for follow-up.

PeppyBooks

Expenses

maps to

Epicor Prophet 21

AP Invoice / Expense Entry

1:1
Fully supported

PeppyBooks Expense records capture date, vendor, amount, CoA debit account, and tax treatment. We migrate expenses as Epicor AP Invoice or Expense Entry records, mapping PeppyBooks tax codes to Epicor's equivalent tax authority setup. PeppyBooks Malaysia SST postings tied to inventory movements receive dedicated tax-code mapping to ensure both financial records and stock valuation carry forward correctly.

PeppyBooks

Manual Journals

maps to

Epicor Prophet 21

GL Journal Entry

1:1
Mapping required

PeppyBooks journal entries support multi-line debits and credits with optional references to invoices or expenses. We export full journal entries including all line items and create Epicor GL Journal Entry records. PeppyBooks journal-entry naming conventions and reference fields map to Epicor Journal Entry description and explanation fields. Entry dates and posting periods migrate to ensure period assignment is preserved.

PeppyBooks

Products

maps to

Epicor Prophet 21

Part

1:1
Fully supported

PeppyBooks Product master records include name, SKU, unit price, cost, tax category, and stock-on-hand at Premium and above. We migrate products 1:1 to Epicor Part master records, treating stock levels as on-hand quantity in Epicor's primary Site. PeppyBooks product categories map to Epicor Product Group codes. Unit of measure from PeppyBooks maps to Epicor Part's UOM configuration.

PeppyBooks

SKUs

maps to

Epicor Prophet 21

Part Number / Part Xref

1:1
Fully supported

PeppyBooks SKU codes migrate to Epicor Part Number with alternate part number (Xref) records created where multiple SKU formats exist. Epicor's alternate part number cross-reference table handles scenarios where PeppyBooks customers used supplier-specific or customer-specific SKU formats. We preserve the original PeppyBooks SKU as an Xref to support incoming POs or SOs referencing the old code.

PeppyBooks

Multi-Store / Warehouses

maps to

Epicor Prophet 21

Site / Warehouse

1:1
Mapping required

PeppyBooks Warehouse assignments are only available on Premium and Ultimate tiers. Where a customer uses multiple stores, we map warehouse locations to Epicor Site and Warehouse entities. Epicor's multi-site architecture supports transfer orders and inter-site inventory visibility that PeppyBooks does not provide, so we configure Site relationships during migration to enable these workflows post-migration.

PeppyBooks

Purchase Orders

maps to

Epicor Prophet 21

PO Header + PO Release

1:1
Mapping required

PeppyBooks Purchase Orders are available at Premium tier and above. We export PO headers and line items, mapping PeppyBooks PO statuses to Epicor PO states (open, pending, closed). PeppyBooks PO approval workflows do not migrate; we document the approval chain as a configuration item for Epicor's PO workflow setup. Line items resolve Part and Vendor references at migration time.

PeppyBooks

Sales Orders

maps to

Epicor Prophet 21

Sales Order

1:1
Mapping required

PeppyBooks Sales Orders support conversion to invoices. We export order headers, line items, and fulfillment status, then create Epicor Sales Order records. Order-to-invoice conversion logic from PeppyBooks is noted and mapped to Epicor's order billing and fulfillment rules. Open orders migrate as active Epicor SOs; closed and fulfilled orders migrate as historical records.

PeppyBooks

Batches / Lot Numbers

maps to

Epicor Prophet 21

Lot / Serial Number

1:1
Fully supported

PeppyBooks batch tracking is available at Ultimate tier. Where a customer uses batch tracking, we migrate lot numbers to Epicor's Lot/Serial number tracking linked to Part records. Epicor's lot traceability supports full FIFO and FEFO costing methods; we flag any PeppyBooks lot expiration dates for Epicor's lot-specific cycle counting setup. If PeppyBooks batch data is absent, we initialize lot tracking as not lot-controlled for migrated stock.

PeppyBooks

Leads

maps to

Epicor Prophet 21

Lead / Prospect

1:1
Mapping required

PeppyBooks CRM holds Leads with source, status, owner, and custom fields. Epicor ERP's CRM module uses a different lifecycle model. We map PeppyBooks Leads to Epicor Lead or Prospect records, preserving source attribution and lead scoring values. PeppyBooks pipeline stage names export and are mapped to Epicor's lead status configuration during CRM module setup.

PeppyBooks

Deals / Pipeline Stages

maps to

Epicor Prophet 21

Quote / Opportunity

1:1
Mapping required

PeppyBooks Deals carry value, stage, expected close date, and associated contact or company. Epicor's manufacturing-oriented CRM model uses Quotes and Orders as the primary sales document rather than Deals. We map PippyBooks Deal values to Epicor Quote records with the expected revenue amount and close date. Pipeline stage names are fully customizable in PeppyBooks; we export the active stage map and apply a naming convention to Epicor's Quote or Lead status values.

PeppyBooks

Activities

maps to

Epicor Prophet 21

Activities / Notes

1:1
Mapping required

PeppyBooks Activity records capture calls, emails, notes, and tasks linked to contacts or deals. We export activities and create Epicor Activity records linked to the corresponding Customer, Vendor, Part, or Order. PeppyBooks activity-type taxonomies differ from Epicor's; we map call records to Epicor Activity with activity type Phone Call, emails to Email, and notes to Note. Historical activity timestamps and owner assignments migrate to preserve the audit trail.

Pair-specific challenges

  • PeppyBooks has no published public API for programmatic export

    PeppyBooks does not publish a public API reference with authentication method, endpoint list, or rate-limit specs. The marketing materials mention APIs and webhooks for the Customer Online Order Portal, but no standalone API documentation is publicly available. This means we cannot authenticate programmatically to pull data during migration scoping. We handle this by requesting CSV exports and direct database access where possible, or by using the portal sync as a channel for customer-data records if the customer has that module active. We recommend requesting a full data export from PeppyBooks support before migration scoping begins.

  • BOM hierarchy mapping requires parent-child resolution

    PeppyBooks has no native BOM management, so customers who have been tracking bills of materials in spreadsheets or outside the system must document them before migration. Epicor ERP uses multi-level BOM structures with revision control, phantom assemblies, and substitute parts. We import BOM data into Epicor Part Bill of Materials records with parent-part and material-part resolution. If PeppyBooks data does not include a structured BOM format, we work from customer-provided spreadsheets and convert them to Epicor multi-level BOM entries during migration.

  • Epicor financial data conversion requires GL segment alignment

    Epicor ERP uses a segmented GL Account structure (Company, Division, Department, Account) rather than flat account codes. PeppyBooks CoA export may use a flat numbering scheme that does not align with Epicor's segment hierarchy. We create a segment-mapping configuration before GL data migration, map each PeppyBooks account to the appropriate Epicor account segment combination, and validate that the resulting Epicor trial balance matches the PeppyBooks trial balance. ERP conversion forums note that financial data integrity failures are among the most common migration issues when GL alignment is not verified before transaction migration.

  • Tier-gated features create schema gaps in migrated data

    Inventory tracking (Products, SKUs, Warehouses) is only available on PeppyBooks Premium and above. Projects and time tracking are a separate Professional plan add-on. Multi-branch accounting and manufacturing are Ultimate only. When migrating from PeppyBooks, records tied to locked features on the customer's current tier cannot be present in the export. We surface any tier-related schema gaps at scoping and flag them as configuration items for Epicor's corresponding module setup. PeppyBooks customers should confirm their active tier before scoping begins.

  • Tax-code mapping for Malaysia SST requires explicit reconciliation

    PeppyBooks has dedicated SST reporting tools and MySST export for Malaysian businesses, but US and Malaysian tax regimes differ fundamentally. Epicor ERP uses Tax Business Unit configuration with tax codes tied to GL accounts and inventory valuation. When migrating transactions that carry PeppyBooks tax codes, we map each code to an Epicor Tax Code with the corresponding authority, rate, and GL account assignment. SST postings tied to inventory movements require Epicor's tax-and-inventory reconciliation report post-import to catch mismatches that could affect stock valuation.

Migration approach

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

  1. Discovery and export acquisition

    We audit the PeppyBooks account across tier (Growth/Premium/Ultimate/Professional), active modules, export availability, and data volume. Because PeppyBooks has no public API, we request CSV exports directly from the customer or via PeppyBooks support. We also request the Chart of Accounts export first, as it drives the GL segment mapping configuration in Epicor. The discovery output is a written migration scope, GL segment mapping plan, and a data delivery checklist for the customer.

  2. GL account design and segment mapping

    We design the Epicor GL Account structure based on the customer's organizational hierarchy. Epicor's segmented account model supports Company, Division, Department, and Account dimensions. We map each PeppyBooks CoA entry to the appropriate Epicor segment combination, create any new Epicor GL accounts, and configure the fiscal year and period setup in Epicor to match PeppyBooks. GL segment mapping must be validated before any transaction data migrates because all financial records reference GL accounts.

  3. Master data migration and reconciliation

    We migrate PeppyBooks Customer and Vendor master records first, establishing the party records in Epicor. Opening balances for AR and AP carry forward as aging entries. Products and Parts migrate next with SKU cross-references created for alternate part numbers. Warehouse locations from PeppyBooks map to Epicor Site and Warehouse entities. Each master data phase emits a row-count reconciliation report before the next phase begins.

  4. Purchase and Sales Order migration

    Open Purchase Orders and Sales Orders migrate with line-item detail, Part references resolved to Epicor Part numbers, and Vendor or Customer references resolved to Epicor party records. PeppyBooks PO and SO approval workflows do not migrate; we document the approval chain as a configuration note for Epicor's workflow setup. Closed and historical orders migrate as posted records with status preserved.

  5. Transaction history and BOM import

    Historical invoices, expenses, and journal entries migrate to Epicor GL with GL account references resolved from the segment mapping. If the customer has documented BOM structures from PeppyBooks Ultimate tier, we import them as Epicor Part Bill of Materials with multi-level revision control. Lot and serial number data migrates where it exists. Epicor's GL validation report confirms that debits equal credits after transaction migration.

  6. Cutover, validation, and CRM handoff

    We freeze PeppyBooks 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 CRM pipeline and automation inventory document for the customer's admin team to configure in Epicor's CRM module or pass to an Epicor implementation partner. We support a one-week hypercare window where we resolve reconciliation issues raised by the customer's team. We do not rebuild PeppyBooks automations, workflows, or pipeline configurations inside the migration scope.

Platform deep dives

Context on both ends of the pair

Source

Strengths

  • US-aligned Chart of Accounts pre-built for IRS and sales-tax reporting requirements.
  • Bundled CRM and accounting eliminates separate system purchases and data re-entry for small businesses.
  • Tiered inventory management scales from simple product tracking to multi-warehouse SKU and batch management.
  • Multi-currency handling with configurable exchange rate management across transactions.
  • Cloud-based access with user-role permissions and read-only accountant sharing built in.

Weaknesses

  • No publicly documented public API with published authentication, rate limits, or endpoint schema, limiting programmatic integrations and migration tooling.
  • Manufacturing, lot tracking, and multi-branch accounting are locked behind the highest Ultimate tier, pricing out smaller businesses with those needs.
  • Project management features are a separate Professional tier add-on not included in the core accounting or CRM plans.
  • Tax compliance tools are US and Malaysia SST/GST focused; multi-state US sales tax automation and EU VAT are not documented as built-in features.
  • No published data export or backup mechanism in the marketing materials, which raises data-portability concerns for customers considering migration.

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.
