Overview
PeppyBooks and Acumatica are architecturally different ERPs. PeppyBooks targets US small businesses with integrated CRM and basic inventory in a single-entity, per-user model. Acumatica targets mid-market manufacturers, distributors, and professional services firms with unlimited-user licensing, multi-entity support, branch-and-subaccount GL, configurable tax zones, and project billing. That structural gap is where most migration effort concentrates. FlitStack AI migrates all PeppyBooks master data and open transactions: customers, vendors, products (as stock or non-stock items), open AR/AP invoices, and contacts. We map the PeppyBooks chart of accounts to Acumatica's branch-and-subaccount hierarchy, which requires a design step we deliver before any data loads. We also configure Acumatica's base setup — customer classes, vendor classes, tax zones and agencies, payment terms, and warehouse locations — from your PeppyBooks configuration data. What PeppyBooks stores outside standard objects (workflow rules, approval chains, email templates) does not migrate. We export those definitions as reference documents for your Acumatica admin to rebuild in Acumatica's automation tools. The migration runs via PeppyBooks API and CSV export, transforms to Acumatica import format (CSV or REST), and loads through Acumatica's import tools. A sample migration with field-level diff validates every mapping before the full run commits.

Object mapping
Each row shows how a PeppyBooks object lands in Acumatica, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
PeppyBooks
Client
Acumatica
Customer
1:1PeppyBooks clients migrate as Acumatica Customers. PeppyBooks does not store Customer Class, so we assign a default class during migration and surface it in the migration plan for your admin to refine per customer group before the full run. Where PeppyBooks stores customer type or industry codes, we use those to inform class assignments. All default class assignments are flagged in the migration plan and can be adjusted before the full migration runs, particularly for customers with distinct payment terms or credit limits.
PeppyBooks
Vendor
Acumatica
Vendor
1:1PeppyBooks vendors migrate as Acumatica Vendors. Payment terms and Tax ID (if populated in PeppyBooks) map to the corresponding Acumatica Vendor fields; if PeppyBooks stores tax IDs in a custom field, we surface the mapping in the plan. We also preserve vendor classification data, including any vendor categories or type codes from PeppyBooks, to inform vendor class assignments in Acumatica for downstream purchasing workflows.
PeppyBooks
Chart of Accounts (Accounts List)
Acumatica
GL Account + Branch
1:1The PeppyBooks chart of accounts is the migration's largest structural challenge. PeppyBooks stores account names as a flat list; Acumatica requires a Branch + Subaccount structure. We analyze all PeppyBooks accounts by type (Asset, Liability, Equity, Revenue, Expense) and propose a branch-and-subaccount hierarchy during the discovery step before any data loads. The proposed hierarchy preserves account balances in the correct segments and is reviewed with your Acumatica admin before any GL data is loaded.
PeppyBooks
Sales Invoice
Acumatica
AR Invoice
1:1Open PeppyBooks sales invoices migrate as Acumatica AR Invoices with Customer, Invoice Nbr., Invoice Date, Due Date, and Payment Terms preserved. Line items map to Invoice Details with Inventory ID, Description, Qty., and Unit Price. We also map PeppyBooks tax codes to Acumatica Tax Categories and apply the appropriate Tax Zone from the tax configuration plan. All migrated invoices retain their original PeppyBooks IDs in a custom field for traceability.
PeppyBooks
Purchase Invoice
Acumatica
AP Invoice
1:1Open PeppyBooks purchase invoices migrate as Acumatica AP Invoices. Vendor, Invoice Nbr., Invoice Date, and Due Date carry over; line items map with Inventory ID or Expense Account, Description, Qty., and Unit Cost. PeppyBooks tax codes map to Acumatica Tax Categories, and the vendor's assigned Tax Zone applies the correct tax jurisdiction. Reference numbers and internal notes from PeppyBooks are preserved in Acumatica's invoice record.
PeppyBooks
Product (Inventory-tracked)
Acumatica
Stock Item
1:1PeppyBooks products flagged as inventory items become Acumatica Stock Items. If PeppyBooks does not store a valuation method, we default to Average cost and flag each item for your admin to set the correct Method (Standard, Average, FIFO, Lot-Specific) before the migration finalizes. We also map PeppyBooks item types, lot numbers, and reorder points to the corresponding Acumatica Stock Item fields including ValMethod, LotSerClass, and ReorderPoint.
PeppyBooks
Product (Non-inventory)
Acumatica
Non-Stock Item
1:1PeppyBooks products not tracked in inventory become Acumatica Non-Stock Items — used on quotes, sales orders, and purchase orders without stock implications. Non-Stock Items carry over the product description, default unit of measure, and any standard pricing from PeppyBooks. They are created with Item Type = Non-Stock Item and can be flagged as expense or service items depending on their usage in PeppyBooks.
PeppyBooks
Sales Order
Acumatica
Sales Order
1:1Open PeppyBooks sales orders migrate as Acumatica Sales Orders with Customer, Order Nbr., Date, and Payment Terms. Line items carry over with Product, Description, Qty., Unit Price, and Tax Group mapped. The customer's assigned Tax Zone applies to each order, and any PeppyBooks shipping or fulfillment notes are preserved in Acumatica's order record for warehouse processing.
PeppyBooks
Purchase Order
Acumatica
Purchase Order
1:1Open PeppyBooks purchase orders migrate as Acumatica Purchase Orders with Vendor, PO Nbr., Date, Delivery Date, and Status. Line items map with Product, Description, Qty., Unit Cost, and Tax Group. PeppyBooks vendor confirmations and internal notes are preserved, and the vendor's Tax Zone and payment terms apply to the Acumatica PO for consistent accounts payable processing.
PeppyBooks
Projects / Milestones
Acumatica
Project (if licensed) / Custom Field
1:1PeppyBooks Projects and Milestones have no direct Acumatica equivalent. We export the project structure as a reference document. If your Acumatica license includes the Projects module, we map to Project tasks and billing rules; otherwise, project data migrates as custom fields or tags on related invoices. The exported reference includes project name, milestone names, milestone dates, milestone amounts, and links to associated invoices and purchase orders.
PeppyBooks
Contact (Client)
Acumatica
Contact
1:1PeppyBooks client contact names and emails migrate as Acumatica Contacts linked to the corresponding Customer record. Primary phone, mobile phone, and job title carry over if populated in PeppyBooks. We preserve the contact's relationship to the PeppyBooks client via the linked Customer record and retain any secondary email addresses stored in PeppyBooks contact records.
PeppyBooks
Tax Code
Acumatica
Tax Zone + Tax Category + Tax Agency
1:1PeppyBooks tax codes become Acumatica Tax Zones scoped to the relevant jurisdiction. Each tax code maps to a Tax Zone with one or more Tax Agencies and a Tax Category for each invoice line. We deliver the tax zone and agency configuration plan before the migration runs. The plan includes the PeppyBooks tax code name, the proposed Acumatica Tax Zone name, linked Tax Agency, and default Tax Category for each line type.

Pair-specific challenges
Migration approach
Extract and analyze PeppyBooks data
We extract all master data from PeppyBooks — chart of accounts, clients, vendors, products, open invoices, and contacts — via API and CSV export. We inventory the full account list, document tax codes, and assess which PeppyBooks products are inventory-tracked versus non-inventory. We also count open invoices and current A/R and A/P balances to size the migration scope. This step produces a data inventory document that drives the Acumatica configuration plan.
Design the Acumatica branch-and-subaccount hierarchy
The PeppyBooks chart of accounts is the migration's most complex structural decision. We analyze every account by type (Asset, Liability, Equity, Revenue, Expense) and propose a branch-and-subaccount hierarchy for Acumatica — typically one branch per legal entity or division, with subaccounts mapping directly to each PeppyBooks account. The resulting account mapping table maps each PeppyBooks account name to its Acumatica Branch and Subaccount IDs and is reviewed with your Acumatica admin before any GL data is loaded.
Configure Acumatica base setup
Before any data loads, we configure Acumatica's foundational records: customer classes and vendor classes (derived from PeppyBooks client types and vendor categories), tax zones and tax agencies (mapped from PeppyBooks tax codes), payment terms, and warehouse or location codes if PeppyBooks uses multiple stores. We deliver this as a configuration checklist that your Acumatica admin can implement, or that we implement directly if given admin access. The configuration must be complete before step 4 begins.
Migrate GL, master data, and open transactions
With accounts and base setup in place, we load data in dependency order: GL accounts and branches first, then customers and vendors with their contact records, then inventory items as Stock Items or Non-Stock Items based on PeppyBooks item type, then open AR and AP invoices, and finally open sales and purchase orders. We also load current A/R and A/P balances as opening balances so Acumatica's trial balance is correct at go-live. Every record is linked to its PeppyBooks source ID via a custom field for traceability.
Run sample migration with field-level diff
A representative slice of data — typically 50–200 records spanning customers, vendors, inventory items, invoices, and orders — migrates first. We generate a field-level diff report comparing every PeppyBooks source field against the corresponding Acumatica destination field so you can verify account mapping (branch-and-subaccount), customer class assignments, tax zone matching, inventory valuation method defaults, and payment term translation before the full run commits.
Full migration and delta pickup
The full dataset loads into Acumatica. A delta-pickup window (typically 24–48 hours after the main load) captures any records created or modified in PeppyBooks during the cutover period. We run a post-migration reconciliation checklist: record counts by object, A/R and A/P balance verification against PeppyBooks reports, and a spot-check of inventory quantities against PeppyBooks stock reports. FlitStack AI's audit log captures every import operation, and one-click rollback is available if reconciliation fails. Once validated, your team goes live in Acumatica and PeppyBooks access is restricted to read-only.
