Overview
Migrating from Fortifi to Nutshell is a CRM-first transition away from an all-in-one platform that bundles billing, marketing, and customer support. Fortifi lacks a publicly documented API, which is the primary constraint shaping the migration approach: export paths must be assessed per customer and may rely on manual UI exports or database-level access rather than programmatic extraction. We map Fortifi Customers to Nutshell People and Companies, Actions to Activities, and Conversations to Deals with pipeline stages configured in Nutshell. Invoice and Subscription records migrate as structured data but require post-migration manual verification since Nutshell has no native billing engine. Automation workflows, dunning sequences, and renewal triggers are configuration-level settings that do not export; we document them for your admin to rebuild in Nutshell or a dedicated billing tool post-migration.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Fortifi 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.
Fortifi
Customer
Nutshell
Person and Company
1:manyFortifi Customers map to Nutshell People with email, phone, and address fields preserved. When a Fortifi Customer has an associated company name, we also create a Nutshell Company record and link it via the Person-Company relationship. We use the company name field from Fortifi as the dedupe key during Company creation and preserve the original Fortifi Customer ID in a custom field for audit traceability.
Fortifi
Action
Nutshell
Activity
1:1Fortifi Actions are behavioral event logs against customers (page views, form submissions, feature usage). We map action type classifications and timestamps to Nutshell Activities with the action type stored as activity details and the original timestamp preserved. If the customer uses Fortifi's action log for sales engagement history, these migrate as Activity records on the linked Person.
Fortifi
Conversion
Nutshell
Deal
1:1Fortifi Conversions represent goal completions tied to marketing or sales workflows. We map conversion records with their attribution data to Nutshell Deals, creating pipeline stages in Nutshell that correspond to the customer's Fortifi conversion funnel stages. Conversion value migrates to Deal value and attribution source data becomes a custom field on the Deal.
Fortifi
Nutshell
Activity (Email type)
1:1Fortifi email records (sent, delivered, opened, bounced states with template associations) migrate as Nutshell Activities linked to the Person record. We preserve email status flags in activity details and migrate campaign attribution data as custom fields on the Activity record. If the customer uses Nutshell's Engagement suite post-migration, these activities inform campaign segmentation.
Fortifi
Interaction
Nutshell
Activity
1:1Fortifi Interactions track customer touchpoints across support and engagement channels. We preserve the interaction log, channel type, and timestamp as Nutshell Activity records. Channel type (email, phone, chat, in-person) migrates as activity details. If Fortifi Interactions reference a specific support or service context, we flag those for the customer to review in Nutshell's task management context.
Fortifi
Invoice
Nutshell
Custom Field Data on Person/Company
lossyFortifi Invoice records carry full financial data including line items, payment status, due dates, and tax codes. Nutshell has no native billing engine, so we migrate Invoice data as structured custom field data attached to the Person or Company record. Payment history and outstanding balances become custom fields. Customers who rely on invoice data for reporting should consider integrating Nutshell with a dedicated billing tool (Stripe, Quadient, or similar) post-migration.
Fortifi
Subscription
Nutshell
Custom Field Data on Person/Company
lossyFortifi Subscription records define recurring billing models, cycles, and plan assignments linked to customers and invoices. We migrate subscription definitions and linked invoice data as custom field data on the Person or Company in Nutshell. Active or cancelled status, billing cycle, and plan name become custom fields. Advanced billing rules (proration, trial periods, usage-based billing) require manual review and cannot be automatically represented in Nutshell's CRM data model.
Fortifi
Custom Properties
Nutshell
Custom Fields
lossyFortifi supports custom fields on Customers and potentially other objects. We discover the custom property schema during scoping and map each to a Nutshell custom field of the closest equivalent type. Multi-value properties map to Nutshell custom fields where supported. Any custom properties without a clear Nutshell equivalent are flagged as custom field data that requires manual categorization post-migration.
Fortifi
User
Nutshell
User
1:1Fortifi User records with role and permission assignments map to Nutshell Users. We resolve by email match and preserve role names as a reference. Active users migrate as active Nutshell Users. If the customer uses Nutshell's free onboarding support, the admin assigns Nutshell permission levels post-migration based on the Fortifi role documentation we provide.

Migration approach
Export path assessment and discovery
We audit the customer's Fortifi account to determine available export options given the lack of documented API. This includes reviewing the admin interface for bulk export functionality, assessing whether database-level access is available, and enumerating all record types and volumes (Customers, Actions, Conversions, Emails, Interactions, Invoices, Subscriptions) plus custom property schemas. We also review active automation configurations, dunning sequences, and renewal rules to document for rebuild. The discovery output is a written export strategy and migration scope document.
Nutshell account provisioning and custom field creation
We provision the Nutshell account at the appropriate tier based on team size and feature needs. We create all required custom fields on People, Companies, and Deals to match the Fortifi custom property schema discovered in step one. We configure pipeline stages in Nutshell that correspond to the customer's Fortifi conversion funnel. If the customer uses Nutshell's Marketing or Engagement suites, we configure those integrations during this phase. The admin receives access to validate the custom field setup before migration data is imported.
Test migration and reconciliation
We run a test migration using the determined export path (API-based, CSV, or hybrid) into the customer's Nutshell account with representative data volumes. The customer's admin reviews the imported records, validates field mapping accuracy on a spot-check sample of 25-50 records, and confirms that custom field data, Person-Company linkages, and Activity history are represented correctly. Any mapping corrections are documented and applied to the production migration plan.
Owner and user mapping
We extract every distinct Fortifi user referenced on customer records, actions, and engagements and match them by email against Nutshell User accounts. Users without matching Nutshell accounts go to a reconciliation queue for the admin to provision. Owner assignments on migrated records (People, Companies, Deals) are resolved at this stage using the validated user mapping.
Production migration in dependency order
We run production migration in record-dependency order: Users (validated), Companies (created first for linkage), People (with Company links resolved), Deals (with pipeline stage and owner resolved), Activity history (Actions, Interactions, Emails via the available export method), Invoice and Subscription data (as custom field attachments), and custom property data. Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, final validation, and automation documentation delivery
We freeze Fortifi write access during cutover, run a final delta migration of any records modified during the migration window, then enable Nutshell as the system of record. We deliver the automation and workflow configuration inventory to the customer's admin for rebuild in Nutshell or a third-party tool. We support a one-week hypercare window to resolve any record reconciliation issues reported by the sales team.
