Overview
Moving from FowCRM to Nutshell is a platform consolidation that resolves FowCRM's opaque pricing and user-minimum gating. FowCRM structures its CRM around Accounts, Contacts, Deals, and Pipelines, with tier-gated Cases and Surveys available only on Professional and Enterprise plans. Nutshell uses Companies, People, Deals, and Pipelines as its primary objects, with a combined People record that holds both contacts and leads under a single model distinguished by a status field. We run FowCRM's two-step Custom Field discovery process (Model enumeration followed by Field fetch) to build a complete field index before any export begins. We migrate standard Accounts, Contacts, Deals, and Activities in dependency order, and conditionally migrate Cases and Surveys only when the customer's FowCRM plan exposes those modules via API. We do not migrate automations, integrations, or webhook subscriptions as these are not accessible via the FowCRM public API. We deliver a written inventory of any active automation for the customer's admin to rebuild in Nutshell post-migration.

Object mapping
Each row shows how a FowCRM 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.
FowCRM
Account
Nutshell
Company
1:1FowCRM Account records map directly to Nutshell Company records. The account name, industry, website, address fields, and any custom properties attached to the Account model migrate as-is. We create Companies first in the migration sequence because every Contact record references an account_id that must resolve at insert time. Account is the migration anchor; no other object can be imported until all Accounts are present in Nutshell.
FowCRM
Contact
Nutshell
People
1:1FowCRM Contact records map to Nutshell People records. We preserve the link to the parent Company by resolving the FowCRM account_id against the Company records inserted earlier, writing the Nutshell Company ID into the People.Company field. FowCRM lifecycle stage and contact status fields migrate as custom fields on People since Nutshell uses a single People object rather than separate Contact and Lead objects. Any FowCRM Contact without an account_id is flagged for the customer to assign a Company manually before migration or to set as a lead in Nutshell.
FowCRM
Deal
Nutshell
Deal
1:1FowCRM Deal records map to Nutshell Deal records. The deal name, amount, expected close date, stage, and pipeline assignment migrate directly. We map FowCRM deal stage values to Nutshell stage values during the scoping phase, flagging any closed-won or closed-lost deals that may carry historical revenue recognition data. Owner assignment migrates by email match against the User mapping. Deals without a resolved Company or People reference are held in a reconciliation queue.
FowCRM
Pipeline
Nutshell
Pipeline
lossyFowCRM Pipelines with configurable stages and probability percentages map to Nutshell Pipeline records. We export each Pipeline's stage definitions, stage order, and probability values and create matching Pipelines in Nutshell before Deal import begins. Stage names that differ between FowCRM and Nutshell are resolved via a mapping table created during scoping. Probability percentages migrate as integer values on the Nutshell stage definition.
FowCRM
Case
Nutshell
People (custom fields)
1:1FowCRM Cases (requests and complaints) are tier-gated on Professional and Enterprise plans only. If the customer's FowCRM plan exposes the Cases module via API, we migrate Case records as custom fields on the related Nutshell People record, with Case status mapped to a custom picklist field and priority mapped to a custom priority field. If the customer's plan is Standard, the Cases endpoint returns 403 and we skip the export gracefully. We check plan tier during discovery and include Case migration only when the API confirms the module is active.
FowCRM
Survey
Nutshell
Custom fields on People/Company
1:1FowCRM Survey definitions and response data are tier-gated on Professional and Enterprise plans. Survey questions and answers are exported as structured JSON and mapped to Nutshell custom fields on the relevant People or Company record. Survey response dates migrate as custom date fields. We treat Survey data as a mapping exercise because Nutshell has no native survey object; the customer reviews the resulting field structure in Nutshell post-migration.
FowCRM
Activity
Nutshell
Activity (calls, emails, meetings, tasks)
1:1FowCRM Activity records (calls, emails, meetings, and tasks) linked to Contacts or Accounts migrate to Nutshell Activity records linked to the corresponding People or Company. We categorize activities by type during the FowCRM export and create matching Nutshell activity records, preserving the activity timestamp, subject, description, and owner assignment. Activities without a resolvable parent People or Company reference are flagged for manual assignment in Nutshell post-migration.
FowCRM
Custom Field
Nutshell
Custom Field
lossyFowCRM Custom Fields are defined per Model and require a two-step discovery process: enumerate all Models first, then fetch Field definitions for each Model. We run the Model enumeration step before any field data export, building a complete model-to-field index that prevents the empty-result issue that occurs when querying Fields directly. Each discovered custom field is typed (picklist, text, date, number) and matched to the equivalent Nutshell custom field type on People, Company, or Deal. We pre-create Nutshell custom fields via the API before data import begins.

Migration approach
Discovery and plan-tier verification
We audit the FowCRM instance by querying its API for active modules, custom field models, and user count. We verify the plan tier by checking which endpoints return data vs 403, particularly the Cases and Surveys modules. We extract the FowCRM contract or invoice to establish user count and active modules for scope confirmation. We document the FowCRM API base URL, authentication method, and any rate-limit headers encountered during discovery.
Custom Field index construction
We run FowCRM's two-step custom field discovery: first enumerate all Models via the /Models endpoint, then fetch Field definitions for each Model via /Models/{id}/Fields. This builds a complete model-to-field index that we cross-reference against Nutshell's custom field API for People, Companies, and Deals. We produce a field-type mapping table (picklist to picklist, text to text, date to date, number to number) and pre-create any missing Nutshell custom fields via the API before data export begins.
Dependency-ordered data export
We export FowCRM data in strict dependency order: Accounts first, then Contacts with account_id references resolved, then Deals with account_id and contact_id resolved, then Cases and Surveys only when the plan tier confirms the modules are accessible. Activities are exported last with their parent record references resolved. Each export phase emits a record-count report that we compare against the Nutshell import counts during validation.
Nutshell import with parent-record resolution
We import Accounts into Nutshell as Companies, then Contacts as People with the Nutshell Company ID resolved from the FowCRM account_id mapping. Deals are imported with the People and Company references resolved, pipeline and stage assignments mapped to the Nutshell pipeline configuration created during setup. Owner assignment resolves by email match against Nutshell Users. Activities import with their People and Company references resolved. Cases and Surveys import conditionally as custom fields on the appropriate People or Company record.
Reconciliation and spot-check validation
We compare FowCRM export record counts against Nutshell import record counts for each object. We spot-check 25-50 records across Accounts, Contacts, Deals, and Activities to verify field-level accuracy and relationship integrity. Any records without resolved parent references are flagged in a reconciliation report for the customer's admin to address in Nutshell before go-live.
Automation inventory delivery and cutover
We deliver a written inventory of any FowCRM workflows, automations, and integrations that require manual rebuild in Nutshell. We do not migrate automations as code. We freeze FowCRM writes during cutover, run a final delta migration for records modified during the migration window, then hand off Nutshell credentials and the migration summary. We support a post-migration reconciliation window for one week. Integration and webhook reconfiguration remains the customer's admin responsibility.
