Overview

What this migration involves

Field Nexus is a field-service management platform built around work orders, dispatch, and technician scheduling. Nutshell is an SMB-focused CRM built around People, Companies, Leads, and Deals with customizable pipeline stages. The two data models diverge significantly: Field Nexus stores operational records (jobs, invoices, time entries) that have no native Nutshell equivalent, while Nutshell's People and Deals model is optimized for sales pipeline tracking. FlitStack AI migrates Field Nexus customers to Nutshell People, companies to Nutshell Companies, and work orders to Nutshell Deals using custom fields for job-level details (service address, assigned technician, service type). Time entries related to work orders migrate as custom time-tracking fields on the deal record. Owner assignment resolves Field Nexus employee email addresses against Nutshell user accounts. We do not migrate routing rules, dispatch logic, or scheduling automations — those have no CRM equivalent and must be rebuilt manually. The migration reads Field Nexus via its REST API (JSON-RPC on the Infor Nexus platform) and writes to Nutshell via the Nutshell REST API.

Why teams make this switch

Two sides of the same decision

Leaving

What's pushing teams away

  • Limited review footprint — the G2 profile has been inactive for over a year with no reviews, and App Store ratings are too sparse to display, making vendor due diligence harder.
  • No published pricing forces every prospect through a sales conversation, slowing comparison with transparent FSM competitors like Jobber or Housecall Pro.
  • API documentation is referenced as available 'for custom integrations' but no developer portal, endpoint reference, or authentication scheme is publicly published.
  • Concentrated regional footprint — the product is positioned for US and Canada operations, limiting fit for international service businesses.
  • Limited public marketing momentum and small social/community presence relative to category leaders raise concerns about long-term product investment for prospects evaluating five-year stacks.

Nutshell

What's pulling them in

  • Lowest cost entry point among mid-market CRMs—Foundation plan starts at $13/user/month, making it accessible for teams validating CRM fit before committing.
  • Integrated sales automation and email sequencing on Pro plans without requiring a separate email marketing platform, per verified Capterra reviews.
  • Consistently praised for intuitive interface and fast onboarding, with case studies reporting 100% team adoption rates within initial deployment periods.
  • Strong customer support responsiveness cited across G2 reviews, with dedicated support tiers available on Enterprise plans.
  • Native integrations with WhatsApp, Facebook Messenger, Instagram, and Slack reduce reliance on third-party middleware for common communication channels.

Object mapping

How Field Nexus objects map to Nutshell

Each row shows how a Field Nexus object lands in Nutshell, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Field Nexus

Customer

maps to

Nutshell

Person

1:1
Fully supported

Field Nexus Customer maps directly to Nutshell Person. Name, email, phone, address, and company association all transfer as standard Nutshell Person fields. Field Nexus contacts without a company link land as standalone People. Additional contact details like job title or birthday are preserved where they map to Nutshell Person fields, and any secondary email addresses are stored in custom fields for reference.

Field Nexus

Customer.company

maps to

Nutshell

Company

1:1
Fully supported

When a Field Nexus Customer record has an associated company, that company name, address, and web domain migrate to a Nutshell Company record. One-to-one mapping; Nutshell Company supports custom fields for additional company-level data from Field Nexus. If a customer belongs to multiple companies in Field Nexus, the primary company link is used for mapping; secondary links are noted in a custom field on the Person record for manual reconciliation.

Field Nexus

WorkOrder

maps to

Nutshell

Deal

1:1
Fully supported

Field Nexus WorkOrder becomes a Nutshell Deal. The work order number becomes the Deal name. Status, description, service address, assigned technician, and service type migrate as custom fields on the Nutshell Deal since Nutshell has no native work order object. Original create and close timestamps are preserved.

Field Nexus

WorkOrder.status

maps to

Nutshell

Deal.Status (custom field)

1:1
Fully supported

Field Nexus work order status values (Scheduled, In Progress, Completed, Cancelled) are mapped to Nutshell Deal stage values via a value-mapping table. Each Field Nexus status value maps to the closest Nutshell pipeline stage, with unmapped values flagged for admin decision before migration.

Field Nexus

WorkOrder.assigned_technician

maps to

Nutshell

Deal.Owner (User lookup)

1:1
Fully supported

The Field Nexus technician assigned to a work order is resolved by email match against Nutshell user accounts. Unmatched technicians are flagged for admin review — they can be invited to Nutshell or assigned to a fallback owner before migration commits.

Field Nexus

TimeEntry

maps to

Nutshell

Deal (custom time tracking fields)

many:1
Fully supported

Field Nexus TimeEntry records associated with a work order are merged into custom time-tracking fields on the Nutshell Deal representing that work order. Total hours, billable hours, and date range are aggregated per deal so the Deal record carries a summary of the labor invested.

Field Nexus

Invoice

maps to

Nutshell

Deal (custom invoice fields) + Attachment

many:1
Fully supported

Field Nexus Invoice records are not native Nutshell objects. Invoice number, amount, status, and date migrate as custom fields on the associated Nutshell Deal. A PDF or CSV export of the invoice is attached to the Deal record for reference.

Field Nexus

Field Nexus Custom Object

maps to

Nutshell

Nutshell Custom Fields (on Person, Company, or Lead)

1:1
Fully supported

Field Nexus custom objects (configured on the Infor Nexus platform with primary, embedded, or configuration designs) do not have a 1:1 Nutshell equivalent. We create custom fields on the appropriate Nutshell object (Person, Company, or Lead) and map custom object field values directly into those custom fields.

Field Nexus

Field Nexus Employee

maps to

Nutshell

Nutshell User

1:1
Fully supported

Field Nexus employee records (technicians, dispatchers, admin staff) resolve by email to Nutshell user accounts. Active Field Nexus employees with Nutshell accounts become Nutshell owners on migrated Deals. Staff without Nutshell accounts are flagged for admin provisioning before migration. If a Field Nexus employee has multiple emails, the primary email is used; mismatches trigger a review flag with the option to assign a fallback owner.

Field Nexus

WorkOrder.service_address

maps to

Nutshell

Deal.custom_address (custom field)

1:1
Fully supported

Field Nexus work order service address (street, city, state, zip, country) migrates as a custom address block on the Nutshell Deal. This preserves the job location separate from the customer contact address, which is especially important for multi-site service organizations.

Field Nexus

Field Nexus Attachment / File

maps to

Nutshell

Nutshell Attachment

1:1
Fully supported

Field Nexus file attachments on work orders (photos, signed forms, service reports) are downloaded and re-uploaded as attachments on the corresponding Nutshell Deal record. File size limits from the Nutshell API apply; files over the limit are split or linked via URL.

Field Nexus

Field Nexus Activity (notes, calls, messages)

maps to

Nutshell

Nutshell Activity / Note

1:1
Fully supported

Field Nexus notes, logged calls, and customer messages associated with a work order or customer record migrate as Nutshell Activity records or Notes on the corresponding Person or Deal. Original timestamps and author attribution are preserved. If a note contains attachments, those files are downloaded and attached to the corresponding Nutshell record, respecting Nutshell's file size limits by splitting large files or linking via URL.

Pair-specific challenges

  • Nutshell has no native work order object — job details require custom fields on Deals

    Field Nexus work orders carry rich job data: service address, assigned technician, service type, start/end times, line items, and signature capture. Nutshell has no native WorkOrder or Job object — it uses People, Companies, Leads, and Deals. We map Field Nexus work orders to Nutshell Deals and use custom fields to preserve service address, assigned technician, service type, and scheduled times. Nutshell custom fields on Deals require the custom field extension pattern, and only the People, Company, and Lead objects support native custom fields — this means deal-level job data lives in a slightly non-standard structure that your admin should be aware of before the migration runs.

  • Field Nexus work order status values require a value-mapping table to Nutshell pipeline stages

    Field Nexus work order statuses (Scheduled, In Progress, On Hold, Completed, Cancelled) do not map 1:1 to Nutshell's default pipeline stages (New, Qualified, Presentation, Proposal, Negotiation, Closed Won, Closed Lost). We build a value-mapping table for each distinct status value in your Field Nexus instance before migration. If your Field Nexus setup uses custom status names not in the mapping table, those records are flagged for admin review before the full run. Mismapped statuses can cause all your migrated deals to land in a single stage, breaking pipeline reporting in Nutshell.

  • Nutshell's per-user pricing model scales linearly — planning headcount matters

    Nutshell charges per user per month, with plans from $13/user/month (Foundation) to $79/user/month (Enterprise). Nutshell's pricing page shows contact-based tiers (up to 100, 500, 1,000 contacts) as add-on bundles, but the core user-seat cost is per-seat. Field Nexus is often priced at a flat org-wide or technician-seat rate. Before migration, project how many Nutshell seats the team actually needs — adding users post-migration triggers billing changes, and Nutshell's support for Enterprise starts at $79/user/month paid annually. We flag the seat count during scoping so your budget reflects the actual Nutshell cost.

  • Time entries and invoice records must be manually reviewed before migration

    Field Nexus time entries and invoices are operational records with no direct Nutshell equivalent. We handle this by aggregating time entry hours into custom fields on the related Nutshell Deal and storing invoice metadata as custom fields, with a PDF/CSV attachment for the full invoice record. However, this means your Nutshell admin should review which time entry fields are most important to preserve before migration. If detailed line-item billing data is needed in Nutshell for reporting, it may require a custom integration or a post-migration data cleanup step to reconcile Nutshell Deals with the original invoice PDFs.

  • Nutshell's API uses Basic Auth with domain/username and API token — impersonation settings affect audit logs

    The Nutshell API authenticates using Basic Auth with a username (domain or email) and an API token. API keys can be configured with impersonation enabled — when impersonation is on, any API action logs as the impersonated user rather than the API key itself. FlitStack uses a dedicated migration API key with impersonation disabled during migration so all records are logged consistently. Your Nutshell admin should verify the migration key has read/write access to People, Companies, Leads, and Deals before migration begins, and should disable impersonation on the migration key for accurate audit trail attribution.

Migration approach

Six steps for a successful Field Nexus to Nutshell data migration

  1. Audit Field Nexus data model and build the value-mapping table

    We connect to your Field Nexus instance via its API to extract all object schemas — standard objects (Customer, WorkOrder, TimeEntry, Invoice, Employee) plus any custom objects defined on the Infor Nexus platform. We then build a value-mapping table for work order statuses to Nutshell pipeline stages, flag any custom object relationships (one-to-one, one-to-many, N:N) that need junction field handling in Nutshell, and surface Field Nexus employee email addresses for owner resolution against Nutshell users. This audit output becomes the migration plan that your admin reviews before we run any data.

  2. Create Nutshell custom fields and provision user accounts

    Before data moves, we create the custom fields on Nutshell Deals needed to hold work order details: service address block, assigned technician reference, service type pick-list, scheduled start and end datetime fields, total hours and billable hours fields, and invoice metadata fields. We also verify that every Field Nexus employee with an active work order has a corresponding Nutshell user account — unmatched employees are flagged so your admin can either invite them to Nutshell or assign a fallback owner before migration.

  3. Resolve owners and run sample migration with field-level diff

    We match every Field Nexus assigned_technician field to a Nutshell user by email. Unmatched records are logged with the technician name and email for admin resolution. We then run a representative sample migration — typically 100–500 records spanning customers, companies, work orders, time entries, and activities — and generate a field-level diff showing every source field, its mapped Nutshell value, and any transformation applied. You verify the sample in Nutshell before the full run commits.

  4. Execute full migration with delta-pickup window

    The full migration runs in dependency order: Field Nexus customers and companies first (to resolve foreign keys), then work orders mapped to Nutshell Deals with all custom fields, then time entries aggregated into deal custom fields, then invoice metadata and attachments. A delta-pickup window of 24–48 hours after the full run captures any new work orders or customer updates created in Field Nexus during cutover. Audit logs record every operation, and one-click rollback is available if reconciliation identifies a mapping error.
