Overview
Moving from Grow CRM to Nutshell is a migration from a self-hosted, all-in-one CRM with integrated project management and invoicing to a SaaS-first sales CRM with unlimited contacts and storage. Grow CRM lacks a public REST API, so all data extraction relies on its built-in CSV export function or direct database queries for self-hosted instances. We handle both extraction paths, normalize the flat CSV structure into parent-child relationships (Contacts to Companies, Deals to Contacts), and pre-create matching custom fields in Nutshell before the import runs. Grow CRM's invoicing, payment, help desk, and project management data do not have native Nutshell equivalents; we convert these to Notes records or document them as excluded scope during scoping. Client portal access credentials are not exportable and must be re-provisioned post-migration. Workflows and automations are documented for manual rebuild and are not migrated as code.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Grow CRM 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.
Grow CRM
Contact
Nutshell
Person
1:1Grow CRM Contact records map directly to Nutshell Person records. Standard fields (name, email, phone, address, tags) migrate via CSV export. Email addresses serve as the dedupe key during Nutshell import. Any custom fields on Contacts in Grow CRM require pre-creation in Nutshell's custom fields section before import; we extract the field definitions from Grow CRM during scoping and document them as a schema specification for the customer to provision before the migration load runs.
Grow CRM
Company
Nutshell
Company
1:1Grow CRM Company records map to Nutshell Company records with a direct field-to-field translation. The Company-to-Person relationship is preserved by resolving the Grow CRM contact-to-company foreign key at import time, linking each Nutshell Person to its parent Company via the Account (Company) lookup. Nutshell does not enforce a strict Account-Contact hierarchy but supports the relationship for reporting.
Grow CRM
Lead
Nutshell
Lead
1:1Grow CRM Lead records migrate to Nutshell Lead records with status, source, and owner assignment preserved. Grow CRM's lead status values map to Nutshell's Lead Status picklist. Owner resolution happens by email match against Nutshell Users; any Grow CRM Owner without a matching Nutshell User enters a reconciliation queue for the customer admin to provision.
Grow CRM
Opportunity
Nutshell
Deal
1:1Grow CRM Opportunities map to Nutshell Deals. Deal value, stage, expected close date, and owner assignment transfer directly. Pipeline stage names from Grow CRM map to Nutshell's pipeline stages, which we configure in Nutshell before the migration import. Grow CRM's deal-to-contact relationship is preserved as the Deal's linked Person in Nutshell.
Grow CRM
Task
Nutshell
Task
1:1Grow CRM Tasks migrate to Nutshell Tasks with status, priority, due date, and assignment preserved. Grow CRM Tasks support custom fields, which are not included in the standard CSV export; we extract custom field definitions from the Grow CRM UI or database during scoping, document them as a schema specification, and require the customer to pre-create matching custom fields in Nutshell before the migration load. Task assignment resolves by email match against Nutshell Users.
Grow CRM
Invoice
Nutshell
Note
lossyNutshell does not have a native invoice object. Grow CRM Invoices (including line items, totals, tax, and payment status) are converted to Nutshell Note records attached to the corresponding Person or Company. The Note body contains a structured summary of the invoice data. Historical paid invoices migrate as closed records; open invoices are flagged for the customer's admin to recreate in a dedicated billing tool post-migration.
Grow CRM
Payment
Nutshell
Note
lossyGrow CRM Payments (amounts, payment gateway, date, linked invoice) do not have a native Nutshell equivalent and are converted to Note records attached to the Person or Company. The Note captures payment date, amount, and gateway (Stripe or PayPal). Full payment reconciliation requires a dedicated accounting or invoicing tool; Nutshell is not designed to replace Grow CRM's financial records.
Grow CRM
Help Desk Ticket
Nutshell
Note
lossyNutshell does not include a native help desk or case management object at the tiers most small teams use. Grow CRM Help Desk Tickets (with status, priority, assignee, and conversation history) are converted to Note records attached to the Person or Company. Conversation threads are preserved as plain text in the Note body. Customers planning to use Nutshell's Enterprise tier with Service Cloud or a separate help desk tool should treat this as a migration of historical context rather than live ticket data.
Grow CRM
Custom Field (Clients, Tasks)
Nutshell
Custom Field
lossyGrow CRM custom fields on Clients (Contacts) and Tasks require manual schema extraction and pre-creation in Nutshell. We document each custom field definition (name, type, picklist options if applicable) from the Grow CRM UI or database during scoping. Nutshell's custom field creation UI is straightforward but must be provisioned before the data import runs; failing to pre-create fields results in import failures for records that reference them. This step is a prerequisite in our migration checklist.
Grow CRM
Tag
Nutshell
Tag
1:1Grow CRM tags on Contacts, Companies, and Opportunities are stored as comma-separated values in the CSV export. We normalize tag values during the transform phase and recreate them as Nutshell Tags, which can be applied to People, Companies, Leads, and Deals. Tag taxonomy is preserved in full.
Grow CRM
Client Portal Access
Nutshell
Not Migratable
lossyGrow CRM client portal access records and login credentials are not included in any export path. Clients who had portal logins must be re-invited in the new system. We flag all Contacts that had portal access in the scoping report so the customer can run a bulk re-invite post-migration. This is a Grow CRM data model constraint and cannot be worked around without Grow CRM database-level access, which is not available for SaaS-hosted Grow CRM instances.

Migration approach
Discovery and extraction path determination
We audit the source Grow CRM instance to determine whether it is self-hosted or SaaS-hosted. For SaaS-hosted instances, we use the built-in CSV export function across all supported object types (Contacts, Companies, Leads, Opportunities, Tasks, Invoices, Payments, Help Desk Tickets). For self-hosted instances, we request direct database read access and extract using structured queries. We document the Grow CRM version, custom field definitions, tag taxonomy, and owner list. We also identify any Contacts with portal access that will require re-invite post-migration. The discovery output is a written extraction plan and a schema specification for any custom fields that need pre-creation in Nutshell.
Custom field pre-creation in Nutshell
We extract all custom field definitions from Grow CRM (name, type, picklist values) and produce a schema specification document. The customer provisions these custom fields in Nutshell before the migration import runs. We provide step-by-step instructions for creating each field type in Nutshell's settings UI. Custom fields that are not pre-created will result in import failures or silent drops for records that carry custom field values. This step is a hard prerequisite; we do not proceed to import without written confirmation that custom fields are configured in the destination.
Transform and relationship reconstruction
Grow CRM's CSV export flattens parent-child relationships. We transform the flat CSV rows by reconstructing the Contact-to-Company relationship using the foreign key stored in the Grow CRM database or exported CSV. We split Opportunities by Contact, resolve Owner email addresses for User matching in Nutshell, normalize tag values, and format invoice and payment data into structured Note bodies. Any Grow CRM Leads are prepared for Nutshell Lead import with status mapping applied. The transform output is a set of staged CSV files organized by object type and load order.
Owner and user reconciliation
We extract every distinct Grow CRM Owner (by email) referenced on Contacts, Companies, Opportunities, and Tasks. We match these by email against the Nutshell destination Users. Any Grow CRM Owner without a matching Nutshell User is placed in a reconciliation queue. The customer provisions missing Users (active or inactive depending on whether the Grow CRM user is still active) before record import begins. OwnerId references are required on standard object imports, so this step gates the import sequence.
Staged import into Nutshell
We run the import in dependency order: Companies first (to establish the Account context), then Persons (with Account lookup resolved), then Leads, then Deals, then Tasks, then Notes (converted from Invoices, Payments, and Help Desk Tickets), and finally Tags. Nutshell's Import2 tool handles standard field mapping for the supported objects. For self-hosted Grow CRM instances with complex custom field structures, we use direct API import with field-level validation. Each phase emits a row-count reconciliation report; the customer spot-checks a sample of records against the source before the next phase begins.
Cutover, validation, and post-migration handoff
We freeze Grow CRM writes during cutover and run a final delta migration of any records modified during the migration window. We validate record counts, spot-check field mappings, and confirm that the Contact-to-Company relationship is intact in Nutshell. We deliver the excluded-scope document (portal re-invite list, workflow inventory, and invoice rebuild checklist) to the customer. We do not rebuild Grow CRM workflows or automations as Nutshell workflows; those are documented for the customer's admin to configure manually. We support a brief hypercare window for reconciliation issues raised within the first week after cutover.
