Overview

What this migration involves

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.

Why teams make this switch

Two sides of the same decision

Leaving

Vault-ERP logo

Vault-ERP

What's pushing teams away

  • Lack of transparent public pricing makes it difficult for prospective customers to budget; many leave before committing when they cannot get clear per-seat or per-module costs upfront.
  • The small team size and limited public documentation create uncertainty about long-term product support and roadmap stability, causing risk-averse buyers to choose more established ERPs.
  • Businesses with highly specialized industry workflows find the customization options insufficient once they scale beyond standard ERP patterns, leading them to platforms with deeper vertical features.

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 Vault-ERP objects map to Acumatica

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

maps to

Acumatica

Customer

1:1
Fully supported

Vault-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

maps to

Acumatica

Vendor

1:1
Fully supported

Vault-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

maps to

Acumatica

InventoryItem

1:1
Fully supported

Vault-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

maps to

Acumatica

GLAccount

1:1
Mapping required

Vault-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

maps to

Acumatica

Project (Contract)

1:1
Fully supported

Vault-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

maps to

Acumatica

ProjectTask

1:1
Fully supported

Vault-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)

maps to

Acumatica

ARInvoice

1:1
Fully supported

Vault-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)

maps to

Acumatica

APBill

1:1
Fully supported

Vault-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

maps to

Acumatica

Employee / User

1:many
Fully supported

Vault-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

maps to

Acumatica

TimeEntry

1:1
Fully supported

Vault-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)

maps to

Acumatica

Custom Field (DAC extension)

1:1
Fully supported

Vault-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

maps to

Acumatica

Note / Attachment

1:1
Fully supported

Vault-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

maps to

Acumatica

SalesOrder

1:1
Fully supported

Vault-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

  • Vault-ERP has no documented REST API — export relies on CSV reports or direct DB access

    Unlike Acumatica which exposes a full REST API and Import by Scenario framework, Vault-ERP has no published API endpoint for programmatic data retrieval. We extract Vault-ERP data through its built-in report export (CSV/Excel) or direct read-only database access if available. This means the extraction layer must be built per customer environment and validated against Vault's current schema before migration runs. Any custom fields or non-standard tables require manual schema discovery, which adds assessment time and cost to the project.

  • Acumatica requires a valid CustomerID before AR invoices can be saved — foreign key sequencing is mandatory

    Acumatica enforces referential integrity at the database level: ARInvoice records must reference a valid CustomerID from the Customer table, and APBill records must reference a valid VendorID. If Vault-ERP invoices reference customers or vendors that were archived or soft-deleted in Vault, those invoices will fail Acumatica validation. We audit all invoice customer references before the migration, create placeholder Customer or Vendor records for orphaned invoice references, and flag any record with a missing parent entity for your team to resolve before the import commits.

  • Acumatica Project/Contract templates define billing rules — Vault project type does not auto-map

    Vault-ERP stores a project type field (e.g., Fixed Price, Time and Materials, Retainer) as free text or a pick-list. Acumatica Project templates (Contract templates) control how revenue is recognized, whether billing is based on trackable costs or fixed schedules, and which GL accounts receive recognized revenue. We cannot infer the correct Acumatica template from Vault's project type without a mapping review. Your team selects the appropriate template per project type, and we create a template-mapping table before the migration runs so every Vault project lands with the correct template ID.

  • Acumatica number sequences are scoped by Branch and DocumentType — Vault's global numbering won't survive the import

    Vault-ERP uses a global sequential number for invoices and bills per module. Acumatica assigns document numbers through Numbering Sequences that are scoped to a Branch and a specific DocumentType (e.g., AR Invoice, AP Bill, Sales Order). If Vault uses sequential invoice numbers like INV-0001, Acumatica will either reject the number format or assign its own sequence number. We preserve Vault's original document numbers as a custom field (OriginalDocNbr__c) on the Acumatica record and configure a separate import-mode numbering sequence that accepts Vault's format without disrupting your production numbering sequence.

  • Vault-ERP custom properties become custom DAC fields — unpublishing a Customization Project can delete them

    Acumatica stores custom fields within a Customization Project. If a project is unpublished or deleted, the custom field is removed from the DAC schema and data stored in those fields becomes inaccessible — not deleted from the database, but invisible to the UI and excluded from standard reports. Vault-ERP custom properties are typically exported as name-value pairs or additional columns. We add these as formal custom fields in a named, stable Customization Project and document the project ID so it is never unpublished post-migration. All custom field data is preserved in Acumatica's database alongside standard fields.

Migration approach

Six steps for a successful Vault-ERP to Acumatica data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.
