Overview
Follow Up Boss and Nutshell take fundamentally different approaches to lead and contact data. Follow Up Boss stores every person in a single unified People object, using stages (New, Active, Client) and Smart Lists to segment contacts. Nutshell splits people into two objects: Leads (unqualified prospects with a Status field) and Contacts (qualified people linked to an Account). FlitStack AI maps each Follow Up Boss Person to a Nutshell Lead or Contact based on the person's current stage — Active and Client stage people land as Nutshell Contacts; New and unsorted people land as Leads. Stage history is preserved in a custom Stage_History__c text field, since Nutshell does not track stage-transition timestamps. Action Plans — Follow Up Boss's automated drip sequences, follow-up triggers, and task-creation rules — have no equivalent construct in Nutshell's workflow engine. We export your Action Plan definitions as a rebuild reference document. Smart List filter logic migrates as saved Nutshell filters, but dynamic segment membership is not preserved. Custom fields (text, date, number, dropdown) map directly to Nutshell custom fields on the appropriate object. Owner resolution happens by email match to Nutshell users before records commit. The migration uses Follow Up Boss's CSV export and JSON-RPC API, constrained by Follow Up Boss's 200-request-per-10-second rate limit, which adds a throttling step to large database exports.

Object mapping
Each row shows how a Follow Up Boss 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.
Follow Up Boss
Person
Nutshell
Lead / Contact
1:manyFollow Up Boss Person maps to Nutshell Lead if the person has no associated Deal or is in the 'New' stage. People in Active or Client stage, or those with a Deal attached, land as Nutshell Contact. The split rule is configurable — teams can specify that all People migrate as Leads and sort in Nutshell afterward.
Follow Up Boss
Company
Nutshell
Account
1:1Follow Up Boss Company maps 1:1 to Nutshell Account. Follow Up Boss stores one primary company per Person; Nutshell Contacts link to one primary Account. If a Follow Up Boss Person has no company, we attach to a placeholder 'No Company' Account or leave the Account field blank, per your configuration preference.
Follow Up Boss
Deal
Nutshell
Deal
1:1Follow Up Boss Deal maps to Nutshell Deal. Nutshell Deals attach to an Account; Follow Up Boss Deals attach to a Person. We resolve the Deal-to-Account link by finding the Person's primary Company (now Account) and linking the Deal to that Account. Deal amount, name, stage, and close date transfer directly.
Follow Up Boss
Stage (Person stage)
Nutshell
Status (Lead) / Stage (Contact)
1:1Follow Up Boss person stage values (New, Active, Client) map to Nutshell's Status field on Lead using a value-by-value lookup table. Client-stage people landing as Contacts use a custom Stage__c field, since Nutshell Contacts do not have a native stage property. Stage-enter timestamps are preserved in a custom field.
Follow Up Boss
Deal Pipeline
Nutshell
Pipeline
1:1Follow Up Boss Deal Pipeline maps to a Nutshell Pipeline. Each Follow Up Boss pipeline becomes one Nutshell pipeline with its own stage set. Stage names map value-by-value. Nutshell supports multiple pipelines with different stage configurations — we create each one during schema setup and map stages per pipeline.
Follow Up Boss
Action Plan
Nutshell
No equivalent
1:1Follow Up Boss Action Plans — automated drip email sequences, SMS auto-replies, task-creation triggers, and lead-routing rules — have no direct equivalent in Nutshell. Nutshell's workflow rules are individual triggers (e.g., 'when lead enters stage, create task') but lack the multi-step sequence builder. We export Action Plan definitions as a structured reference document for your Nutshell admin to rebuild.
Follow Up Boss
Smart List
Nutshell
Saved Filter
1:1Follow Up Boss Smart Lists are dynamic segment definitions based on filter rules (stage, source, custom field conditions). These rules do not auto-migrate. We export Smart List definitions as a filter-reference sheet. Nutshell saved filters replicate the display logic, but dynamic re-evaluation of membership based on real-time changes requires manual filter setup.
Follow Up Boss
Activity (Email, Call, Meeting, Note)
Nutshell
Activity / Note
1:1Follow Up Boss email, call, and meeting activities map to Nutshell Activities. Notes map to Nutshell Notes. Original timestamps, owners, and linked Person/Deal associations are preserved. Nutshell Activities display in the timeline view of the linked Contact or Lead record.
Follow Up Boss
Custom Field (text, date, number, dropdown)
Nutshell
Custom Field
1:1Follow Up Boss custom fields (text, date, number, dropdown types) map to Nutshell custom fields on the corresponding object (Person fields migrate to Lead/Contact custom fields; Company fields to Account custom fields; Deal fields to Deal custom fields). Dropdown fields map value-by-value. Nutshell custom field names follow its labeling conventions — we translate the API name to a readable label during creation.
Follow Up Boss
Owner
Nutshell
User
1:1Follow Up Boss owner ID resolves to a Nutshell User by email address. Unmatched owners are flagged before migration — your team either creates the Nutshell user first or assigns records to a fallback user. Follow Up Boss does not store passwords or permissions, so user access configuration is destination-side work.
Follow Up Boss
Lead Source
Nutshell
Custom field (Lead Source)
1:1Follow Up Boss tracks lead source (referral, portal, website) natively. Nutshell has no standard Lead Source field — we create a Lead_Source__c custom pick-list on the Lead object and populate it with Follow Up Boss source values. Real estate portal sources (Zillow, Realtor.com) migrate as-is; teams rebuilding integrations in Nutshell map those to new source values.
Follow Up Boss
Attachment / File
Nutshell
Attachment
1:1Follow Up Boss file attachments associated with People or Deals migrate as Nutshell Attachments linked to the corresponding Contact or Deal record. Files are downloaded from Follow Up Boss and re-uploaded to Nutshell. File size limits are enforced by Nutshell's storage tier — we flag any file exceeding the destination limit before the full migration runs.

Migration approach
Audit Follow Up Boss data inventory and schema
FlitStack AI connects to Follow Up Boss via your API key and inventories all People, Companies, Deals, Custom Fields, and Action Plans. We document every stage value, pipeline configuration, and Smart List definition. This audit produces the migration scope document: record counts per object, custom field types and choice lists, and an Action Plan inventory that your team reviews before we proceed. No data moves until you sign off on the scope.
Configure Nutshell target schema
We create the custom fields, pipelines, and stage configurations in your Nutshell instance based on the Follow Up Boss inventory. This includes the Lead_Source__c pick-list, Stage__c and Stage_History__c fields, Tags__c, and any deal-level custom fields. If your Nutshell plan supports multiple pipelines, we pre-build the pipeline structure so stage mapping resolves correctly during the data load. Your Nutshell admin grants FlitStack API access before this step.
Export from Follow Up Boss and resolve owners
We export People, Companies, Deals, and Activities from Follow Up Boss using a combination of CSV bulk export and API polling. Follow Up Boss's 200-request-per-10-second rate limit governs the extraction pace. Owner IDs are resolved against Nutshell user email addresses — unmatched owners are flagged in a pre-flight report with your team to decide on fallback assignments before any records commit. Custom field choice values are extracted for dropdown mapping.
Run sample migration with field-level diff
A representative slice of 100–500 records (spanning contacts, leads, accounts, deals, and a few activities) migrates first. We generate a field-level diff between the Follow Up Boss source values and the Nutshell destination values so you can verify stage mapping, owner resolution, and custom field population before the full run. Any mapping corrections happen at this stage — the sample is a dry run, not a commit.
Execute full migration with delta-pickup at cutover
The full dataset loads into Nutshell. A 48-hour delta-pickup window opens at cutover to capture any records created or modified in Follow Up Boss during the migration run. Your team continues working in Follow Up Boss throughout the window — FlitStack uses read-only access. Once the delta window closes, we run a reconciliation report comparing Nutshell record counts and field totals against Follow Up Boss source totals and surface any discrepancies for your review.
Deliver Action Plan export and go-live support
FlitStack AI delivers the structured Action Plan rebuild reference document listing every active plan, its trigger conditions, step sequence, and estimated Nutshell workflow-rule equivalents. Your Nutshell admin uses this as a rebuild checklist. We remain available for 10 business days post-migration to answer mapping questions, correct any field-level discrepancies, and support re-runs if reconciliation reveals gaps. Additionally, we provide a summary of which Action Plan elements have direct Nutshell equivalents versus those requiring alternative workflow configurations.
