Overview

What this migration involves

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.

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

Acumatica logo

Acumatica

What's pulling them in

  • Unlimited user licensing lets companies add staff without per-seat billing shocks, making Acumatica cost-predictable at scale.
  • Flexibility and scalability earn consistent praise — users value a platform that adapts to vertical workflows without forcing a redesign.
  • Real-time visibility across financials, inventory, and projects gives mid-market businesses a consolidated operational view previously available only in enterprise-tier ERPs.
  • Cloud-native architecture with automatic updates removes infrastructure management burden from in-house IT teams.
  • Modular licensing lets companies start with one or two suites (Financials, Distribution) and expand into Manufacturing or CRM incrementally.

Object mapping

How PeppyBooks objects map to Acumatica

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

maps to

Acumatica

Customer

1:1
Fully supported

PeppyBooks 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

maps to

Acumatica

Vendor

1:1
Fully supported

PeppyBooks 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)

maps to

Acumatica

GL Account + Branch

1:1
Fully supported

The 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

maps to

Acumatica

AR Invoice

1:1
Fully supported

Open 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

maps to

Acumatica

AP Invoice

1:1
Fully supported

Open 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)

maps to

Acumatica

Stock Item

1:1
Fully supported

PeppyBooks 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)

maps to

Acumatica

Non-Stock Item

1:1
Fully supported

PeppyBooks 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

maps to

Acumatica

Sales Order

1:1
Fully supported

Open 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

maps to

Acumatica

Purchase Order

1:1
Fully supported

Open 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

maps to

Acumatica

Project (if licensed) / Custom Field

1:1
Fully supported

PeppyBooks 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)

maps to

Acumatica

Contact

1:1
Fully supported

PeppyBooks 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

maps to

Acumatica

Tax Zone + Tax Category + Tax Agency

1:1
Fully supported

PeppyBooks 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

  • Chart of accounts restructuring is the biggest migration effort

    PeppyBooks stores accounts as a flat list of account names with no branches or subsegments. Acumatica requires a Branch + Subaccount hierarchy — for example, PeppyBooks account 'Office Supplies' becomes '0100-6200' (Branch 0100, Subaccount 6200 for Office Expenses) in Acumatica. During migration, we analyze every PeppyBooks account and propose a branch-and-subaccount hierarchy that preserves account balances in the correct segments. This design step must complete before any GL data loads, and the resulting account mapping table becomes part of the migration plan.

  • Tax configuration requires a separate setup phase before invoice migration

    PeppyBooks applies a single tax code per invoice or per line. Acumatica uses a layered tax model: Tax Zones define where tax applies, Tax Agencies define who gets paid, and Tax Categories are assigned per invoice line. A PeppyBooks tax code named 'CA-Sales-Tax' does not automatically become an Acumatica tax zone — it requires a setup plan that names the zone, links the agency, and assigns the category. We deliver that plan before the migration runs, but the actual Tax Zone and Tax Agency records must exist in Acumatica before invoice data can be validated.

  • Inventory valuation method may be absent from PeppyBooks source data

    PeppyBooks does not store a valuation method (Standard, Average, FIFO, Lot-Specific) per product. Acumatica requires this field on every Stock Item — without it, items cannot be correctly posted to inventory subaccounts. We default unvalued items to Average cost and flag each one in the migration plan. If PeppyBooks tracks lot numbers, we map those to Acumatica Lot/Serial classes; if it does not, lot tracking is not created and inventory cost rolls at the item level only.

  • Multi-currency exchange rates must be pre-loaded before transaction migration

    Both PeppyBooks and Acumatica support multi-currency, but they store exchange rates differently. PeppyBooks stores rates in client properties; Acumatica maintains a dedicated Exchange Rates screen with effective dates and inverse-rate relationships. Any PeppyBooks invoice or vendor record in a non-USD currency requires a matching Acumatica exchange rate to be loaded first. We extract PeppyBooks rates during discovery and generate the Acumatica exchange rate import file; if PeppyBooks has no stored rate for a currency pair, we flag it for your admin to provide the historical rate before the migration runs.

  • PeppyBooks project milestones have no Acumatica equivalent without the Projects module

    PeppyBooks ships with a Projects module that tracks milestones and deliverables tied to invoices. Acumatica's equivalent is the Projects module, which requires a separate license on top of Financials. If your Acumatica license does not include Projects, PeppyBooks project data must be stored differently — as custom fields on the related invoices, as tags, or as a reference document. We export the full PeppyBooks project structure (project name, milestone names, dates, and amounts) during migration and surface it in the plan so your admin can decide how to reconstruct the project hierarchy in Acumatica.

Migration approach

Six steps for a successful PeppyBooks to Acumatica data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

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.

Most PeppyBooks to Acumatica migrations complete in 2–4 weeks of clock time for small-to-mid datasets (under 10,000 records). The longest planning step is designing the branch-and-subaccount hierarchy for the chart of accounts, which requires one to two review cycles with your Acumatica admin. Complex migrations involving multi-entity restructuring, multiple inventory warehouses, or extensive multi-currency setup extend to 5–8 weeks. We sequence the work so PeppyBooks users can keep working until the final cutover week.
