Overview
Vault-ERP organizes business data across loosely coupled modules for HR, sales, finance, and projects with custom property extensibility per entity. Acumatica uses a centralized relational schema with mandatory foreign keys, requiring a Project record before project tasks can attach. FlitStack AI sequences the migration so parent entities (GL accounts, customers, vendors, inventory items, projects) load first; dependent records (invoices, bills, project tasks, time entries) resolve their lookups afterward. We export Vault‑ERP data via its CSV export or direct DB read, normalize the flat property model into Acumatica DAC fields, and load through Acumatica's Import by Scenario framework. Custom properties are captured during assessment and added as custom fields in a dedicated Customization Project before data arrives. The migration pipeline runs in stages: GL accounts with Account Classes, then customers with a default CustomerClass (flagging those needing class review), then vendors with Payment Terms IDs, then inventory items with ItemType and warehouse assignments resolved against pre‑created Branch/Warehouse records. Projects are created using templates derived from Vault's project type, ensuring billing rules and cost tracking are set before tasks are added. Invoices, bills, and time entries are imported after parent validation, with Acumatica recalculating line totals via its tax engine. All foreign‑key references are checked in staging, and orphaned references are flagged for resolution. We deliver a process‑rebuild specification that maps Vault workflows, approval thresholds, and custom automations to Acumatica screen‑level configurations and automation steps, enabling your team to rebuild operational logic in the new system.

Object mapping
Each row shows how a Vault-ERP 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.
Vault-ERP
Customer
Acumatica
Customer
1:1Vault-ERP customers map directly to Acumatica Customers. In Acumatica every customer must belong to a CustomerClass that governs terms, credit limits, and financial settings. We assign a default CustomerClass to all migrated records and flag any customer that lacks a class assignment, requiring a review before the import finalizes to ensure downstream invoicing and credit checks operate correctly.
Vault-ERP
Vendor
Acumatica
Vendor
1:1Vault-ERP vendors map to Acumatica Vendors. Vendor payment terms such as Net‑30 or Net‑60 translate to Acumatica Payment Terms IDs, which control due date calculations and early‑payment discounts. If Vault stores multiple payment methods for a single vendor, we consolidate them into a primary vendor record and attach the dominant term, preserving the most relevant payment behavior.
Vault-ERP
InventoryItem
Acumatica
InventoryItem
1:1Vault-ERP inventory items, whether stock, non‑stock, or service, map to Acumatica Inventory Items. The ItemType field in Acumatica distinguishes these categories; we use a value‑mapping to align Vault’s type labels. Warehouse assignments in Vault must reference Branch/Warehouse records created in Acumatica beforehand, so we pre‑create those structures to ensure item location data is valid on import.
Vault-ERP
Chart of Accounts
Acumatica
GLAccount
1:1Vault-ERP GL accounts map to Acumatica GL Accounts. Account type (Asset, Liability, Equity, Revenue, Expense) translates to the Account Class field, which governs posting rules and financial statement grouping. The Active/Inactive status from Vault maps to the Active flag on the GL Account screen, preserving the current usage state of each account in the chart of accounts.
Vault-ERP
Project
Acumatica
Project (Contract)
1:1Vault-ERP projects become Acumatica Project/Contract records. Each Project in Acumatica is linked to a Project template that defines billing rules, revenue recognition method, cost tracking approach, and default GL accounts. We derive the appropriate template from Vault’s project type field, create the template entries before importing projects, and ensure each project’s settings are aligned with its operational characteristics.
Vault-ERP
Project Task
Acumatica
ProjectTask
1:1Vault-ERP project tasks map to Acumatica ProjectTask records. Each task must reference a ProjectID that originates from the migrated Vault project; we load projects first to guarantee the foreign key exists. Tasks are sequenced after their parent project to resolve the reference correctly during import, and any orphaned tasks are held for manual resolution.
Vault-ERP
Invoice (AR)
Acumatica
ARInvoice
1:1Vault-ERP invoices become Acumatica ARInvoice records. The customer reference on each invoice resolves to the migrated CustomerID, and line items use the migrated InventoryItemID where applicable. Acumatica recalculates line totals and tax amounts through its tax engine, so we preserve Vault’s original tax breakdown as a note on the invoice for audit purposes.
Vault-ERP
Bill (AP)
Acumatica
APBill
1:1Vault-ERP bills map to Acumatica APBill records. The vendor lookup on each bill resolves to the migrated VendorID, ensuring the payee is correctly linked. Acumatica computes taxes based on its tax zone configuration, so we store the original tax jurisdiction and rate as a note on the bill, allowing auditors to compare the migrated tax data with Vault’s original breakdown.
Vault-ERP
Employee
Acumatica
Employee / User
1:manyVault-ERP employee records split into two Acumatica entities: attributes such as name, department, and hire date become Employee records, while login credentials and role assignments become Acumatica User accounts resolved by matching email addresses. Employees lacking an email address are flagged for manual User account creation to ensure every owner reference in projects, invoices, or approvals can be resolved.
Vault-ERP
TimeEntry
Acumatica
TimeEntry
1:1Vault-ERP time entries map to Acumatica TimeEntry records linked by EmployeeID and ProjectID. The billable flag translates to the IsBillable field, controlling whether the entry is eligible for billing. If Vault tracks time by individual task, we link the entry to the corresponding migrated ProjectTaskID, ensuring accurate project cost aggregation and invoicing.
Vault-ERP
Custom Property (per entity)
Acumatica
Custom Field (DAC extension)
1:1Vault-ERP custom properties attached to any entity are catalogued during assessment. Each custom property becomes a custom field on the corresponding Acumatica DAC, added via a Customization Project before the import runs. Custom fields are type-aware: text, number, date, and pick-list types map to their Acumatica equivalents.
Vault-ERP
Attachment / File
Acumatica
Note / Attachment
1:1Vault-ERP file attachments associated with any entity are migrated as Acumatica Notes or Files linked to the corresponding record. We download each file from Vault, store it in Acumatica’s file repository, and attach it using the NoteID reference on the parent entity. The original file name, MIME type, and creation date are preserved as metadata on the Note record to maintain audit trails.
Vault-ERP
SalesOrder
Acumatica
SalesOrder
1:1Vault-ERP sales orders map to Acumatica SalesOrder records. The order status (open, completed, cancelled) translates to the corresponding Acumatica status field, preserving the current lifecycle state. If Vault records multi‑step fulfillment stages, we capture those as a fulfillment workflow note that can be referenced when configuring Acumatica’s warehouse management, ensuring that shipping and inventory allocation logic aligns with the original process.

Pair-specific challenges
Migration approach
Assess Vault-ERP export surface and Acumatica target schema
We inventory Vault-ERP entities in use — customers, vendors, inventory items, GL accounts, projects, invoices, bills, time entries, employees, and any custom properties. For each entity we confirm the export method: built-in report CSV, direct DB read, or manual extraction. We simultaneously map the Acumatica tenant schema — branches, organizations, numbering sequences, tax zones, and payment terms — so the target environment is ready before data lands. This step produces a migration plan document with entity counts, foreign key dependencies, and a sequenced import order.
Create Acumatica branches, warehouses, and numbering sequences
Acumatica requires its organizational structure in place before records import. We create Branch records matching Vault-ERP's company or department entities, set up Warehouse records for inventory, configure GL Account Classes and the chart of accounts, and define Numbering Sequences for each document type. Payment terms, customer classes, and vendor classes are configured at this stage. We also create the Customization Project and add any custom fields mapped from Vault-ERP custom properties so they exist in the schema before the first import record arrives.
Migrate parent entities first (customers, vendors, inventory, GL accounts, projects)
We sequence the migration to resolve foreign keys in dependency order: GL accounts, then customers and vendors, then inventory items, then projects. Each entity's migration runs with a field-level diff — we compare source values against the imported Acumatica values and surface discrepancies before committing. Employee records migrate next with email-to-user resolution so Acumatica User accounts exist for any owner or project manager references in later entities. Unresolved foreign keys (e.g., an invoice referencing a deleted Vault customer) are flagged and held in a staging table for your team to resolve.
Migrate transactional entities with delta-pickup window
With parent entities in place, we migrate invoices, bills, project tasks, and time entries. Transactions carry original document dates, amounts, and tax totals. We run a sample migration of 200–500 records spanning each entity type first, generating a field-level diff against Acumatica for your review. After sample approval, the full migration runs. A delta-pickup window opens simultaneously — any Vault-ERP records created or modified during the migration window are captured and appended to the Acumatica load before final reconciliation.
Reconcile, validate totals, and deliver rollback package
We compare Vault-ERP record counts and financial totals (accounts receivable, accounts payable, inventory on-hand, project budget totals) against Acumatica's summary reports. Discrepancies are traced to the source record and corrected in the import. All migration operations are logged to an audit file. If reconciliation fails, a one-click rollback reverts Acumatica to its pre-migration state. We deliver a process-rebuild specification document mapping Vault-ERP workflows, approval rules, and automations to their Acumatica equivalents (screen-level configuration, screen-level approvals, or automation steps using Acumatica's automation engine) so your team can reconstruct operational logic post-migration.
