Overview

What this migration involves

LeadManaging organizes multifamily leasing data around a flat lead model: contacts, companies, and deals share a simpler schema than most CRMs. Nutshell structures its CRM around three distinct objects — People, Companies, and Leads — with custom fields for extensibility and separate pipeline configuration. The migration from LeadManaging to Nutshell carries your contact records, company records, deal/pipeline data, and activity history into Nutshell's object graph, while creating custom fields for LeadManaging-specific properties that have no native Nutshell equivalent. FlitStack AI sequences the migration to preserve foreign-key relationships: companies land first, then people with their primary company link, then leads and deals that reference those companies and people. Custom properties from LeadManaging migrate as Nutshell custom fields on the appropriate object — People, Company, or Lead — so your team retains visibility into property-level context without manual re-entry. Activity records (calls, emails, meetings, notes) transfer with original timestamps and owner attribution. The migration uses Nutshell's JSON-RPC API with scoped read access to the source system, keeping your LeadManaging account fully operational during cutover. A 24–48 hour delta pickup window captures in-flight changes made during the transition.

Why teams make this switch

Two sides of the same decision

Leaving

LeadManaging logo

LeadManaging

What's pushing teams away

  • Limited scalability for portfolios with hundreds of units or multiple properties: the platform was designed for individual leasing offices, not enterprise property management companies.
  • No public API means integrations with custom tools or in-house systems require workarounds or manual data entry.
  • Customer support responsiveness is inconsistent, with reviewers noting slow response times on technical issues.
  • Reporting depth is shallow compared to dedicated property management analytics tools, particularly for cohort analysis across multiple properties.
  • The platform has not released major feature updates visible in public changelogs, leaving teams uncertain about the product roadmap.

Choosing

Nutshell logo

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 LeadManaging objects map to Nutshell

Each row shows how a LeadManaging 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.

LeadManaging

Lead / Contact record

maps to

Nutshell

Person (People object)

1:1
Fully supported

LeadManaging's person data maps directly to Nutshell's Person object. Name, email, phone, job title, and address fields transfer as-is. The person's primary company association resolves to a Nutshell Company record that must be created first to satisfy the foreign-key relationship.

LeadManaging

Lead / Company name

maps to

Nutshell

Company (Account)

1:1
Fully supported

When LeadManaging stores an organization name on a lead, FlitStack extracts it as a standalone Company record in Nutshell. If the company name is blank or ambiguous, a placeholder company record is created and flagged for your team to verify and rename.

LeadManaging

Lead / Deal / Opportunity

maps to

Nutshell

Lead (Opportunity)

1:1
Fully supported

LeadManaging deals and opportunities map to Nutshell Leads. The deal name, amount, close date, and stage all transfer. Nutshell Lead Confidence (0–100 rating) can receive a mapped value if your source has a comparable score; otherwise it defaults to 50 and can be updated manually after migration.

LeadManaging

Lead / Pipeline name

maps to

Nutshell

Pipeline (Nutshell Pipeline)

1:1
Fully supported

LeadManaging pipeline names map to Nutshell Pipeline objects. Each pipeline in the source becomes its own Nutshell Pipeline with named stages. Stage order and labels are preserved; stage probability is not carried over unless your source stores explicit probability values, since Nutshell stages do not have native probability fields.

LeadManaging

Lead / Lead status

maps to

Nutshell

Lead status field

1:1
Fully supported

LeadManaging lead status values (New, Contacted, Qualified, Lost, Won) map to Nutshell's Lead Status pick-list. We apply a value-by-value mapping — statuses that have no exact Nutshell equivalent receive the closest available option and are flagged in the mapping plan for your review before the migration runs.

LeadManaging

Lead / Custom properties

maps to

Nutshell

Custom fields (Person / Company / Lead)

1:1
Fully supported

LeadManaging custom fields — such as lease_type, unit_number, move_in_date, or referral_source — do not have a native equivalent in Nutshell. FlitStack creates matching custom fields on the appropriate Nutshell object (Person, Company, or Lead) before the migration, preserving the original data type and any pick-list values the field uses.

LeadManaging

Lead / Tags

maps to

Nutshell

Custom field (text or picklist)

1:1
Fully supported

LeadManaging's tag model has no direct Nutshell equivalent. Tags migrate as a text custom field storing comma-separated values, or as a multi-select pick-list if the total tag set is small and well-defined. Teams that rely heavily on tagging for segmentation should review the resulting field in Nutshell and consider using Nutshell's built-in filters instead.

LeadManaging

Call / Email / Meeting / Note

maps to

Nutshell

Activity (calls, emails, meetings, notes)

1:1
Fully supported

Activity records from LeadManaging map to Nutshell Activities. Calls become call activities, emails become email activities, meetings become meeting activities, and notes become note records — all linked to the correct Person, Company, or Lead. Original timestamps and owner attribution are preserved on each record.

LeadManaging

Attachment / File

maps to

Nutshell

File (Nutshell Files)

1:1
Fully supported

File attachments stored against lead records in LeadManaging are downloaded and re-uploaded to Nutshell's file storage. Nutshell's file size limits apply; files exceeding the limit are flagged for manual re-upload by your team. Inline images in notes are extracted, re-hosted, and the note body is updated with the new image URLs.

LeadManaging

Owner / Assigned user

maps to

Nutshell

Owner (Nutshell user)

1:1
Fully supported

LeadManaging owner assignments resolve by matching the owner's email address to a Nutshell user. If no matching Nutshell user exists, the record is assigned to a designated fallback owner and flagged in the migration report. You should ensure all active LeadManaging users have been invited to Nutshell before the migration date.

LeadManaging

Lead / Lead Confidence

maps to

Nutshell

Lead Confidence (custom numeric field)

1:1
Fully supported

If LeadManaging stores a numeric confidence or priority score on leads that has no direct equivalent in Nutshell, we migrate it as a custom numeric field on the Lead object. Nutshell's native Lead Confidence (0–100 rating) coexists with this field; your team can choose which to use for pipeline sorting.

LeadManaging

Lead / Address fields

maps to

Nutshell

Address field (on Person or Company)

many:1
Fully supported

LeadManaging stores address components separately (street, city, state, zip, country). These merge into Nutshell's single-line address field. When multiple address records exist for one person, FlitStack selects the most recently modified address by default and surfaces any alternates as a note on the Person record.

Pair-specific challenges

  • LeadManaging's flat lead record requires disambiguation in Nutshell's three-object model

    LeadManaging often stores person details and property details in a single lead record — the person's name, the leasing property, the unit, and the deal terms all live together. Nutshell separates these into a Person record linked to a Company record linked to a Lead record. FlitStack disambiguates this by first creating Company records from organization names found in lead data, then linking the person data to those companies, then attaching the deal and property-level fields to the resulting Lead record. Any lead records that lack an organization name produce a placeholder Company that your team should rename after migration to maintain clean Nutshell company records.

  • Custom properties need Nutshell custom fields created before data lands

    LeadManaging's custom fields — such as lease_type, unit_number, referral_source, or move_in_date — have no native Nutshell equivalent and must be created as custom fields on the appropriate Nutshell object (Person, Company, or Lead) before the migration loads any data. FlitStack delivers a custom-field creation plan listing every LeadManaging property, its data type, and the recommended Nutshell object for hosting it. If your LeadManaging setup has more than 20 custom fields, the schema setup phase extends the timeline because Nutshell's custom-field UI requires each field to be created individually and the mapping validated against each one.

  • Nutshell's JSON-RPC API uses basic-auth credentials and has different pagination behavior than REST

    Nutshell's API is a JSON-RPC endpoint at app.nutshell.com/api/v1/json using HTTP Basic Authentication with an API key and either a domain/username or impersonation email. This differs from the REST API patterns common in other CRMs. FlitStack's integration layer handles JSON-RPC request formatting and authentication, but teams should ensure they generate an API key in Nutshell with the appropriate impersonation permissions enabled if user attribution on migrated activities matters — without impersonation enabled, all API-created activities appear under the API key name rather than the original activity owner.

  • Tag-based segmentation has no native Nutshell equivalent and requires a custom field strategy

    LeadManaging commonly uses tags to categorize leads by source campaign, leasing property, or agent assignment. Nutshell does not have a native tagging system — tags must be represented as either a text custom field storing comma-separated values or as individual pick-list entries if the tag set is small and static. FlitStack recommends the pick-list approach for tag sets under 30 distinct values, as it enables Nutshell's built-in filtering. For larger or frequently-changing tag sets, the text-field approach preserves all tag data but requires manual grouping in Nutshell after migration.

  • File attachments may require manual re-upload if they exceed Nutshell's file size limits

    LeadManaging stores file attachments against lead records — lease documents, application PDFs, correspondence attachments. Nutshell's file storage has size limits per attachment. FlitStack downloads all attachments from LeadManaging during the migration, checks each file against Nutshell's current size constraints, and re-uploads files that fit. Files that exceed the limit are flagged in the migration report with their original names and sizes, and your team receives step-by-step instructions for re-uploading them manually to the correct Nutshell record after go-live.

Migration approach

Six steps for a successful LeadManaging to Nutshell data migration

  1. Audit LeadManaging data and build the mapping specification

    FlitStack connects to your LeadManaging instance using scoped API credentials and exports all active records — people, companies, leads, deals, and activities. We cross-reference every field against Nutshell's schema to identify direct matches, custom field requirements, and any pick-list value mappings. The result is a field-level mapping specification delivered for your review before any data moves. This step also identifies orphaned records (people without companies, leads without owners) so your team can resolve them before migration day.

  2. Create Nutshell custom fields and configure pipelines

    Before data lands, FlitStack delivers a custom-field creation plan listing every LeadManaging property that requires a new Nutshell field — the field name, data type, and object to attach it to. Your Nutshell admin creates these fields (or FlitStack creates them via the API where permitted). We also provide pipeline configuration notes so your team can set up Nutshell Pipelines with stage names matching your current LeadManaging deal stages. This step runs in parallel with your data-cleanup review.

  3. Migrate companies and people first, then leads and deals

    Nutshell's foreign-key model requires Companies to exist before People can reference them, and People to exist before Leads can be associated with them. FlitStack sequences the migration in dependency order: Companies land first, then People with their primary company link resolved, then Leads and deals that reference those companies and people. Activity records (calls, emails, meetings, notes) are loaded after their parent records exist so the relationship links are valid. Each batch runs with a validation pass that checks record counts and field-level integrity before the next batch starts.

  4. Run a sample migration and generate a field-level diff

    A representative slice — typically 100–300 records spanning people, companies, leads, and activities — migrates first and lands in Nutshell for your team to verify. FlitStack generates a field-level diff comparing source values against destination values for every mapped field. You can confirm that custom property values appear correctly, that owner attribution maps to the right Nutshell users, and that pipeline names are preserved. This step surfaces any mapping corrections before the full migration commits.

  5. Execute full migration with delta pickup and rollback window

    The full dataset migrates against Nutshell using the validated mapping. A 24–48 hour delta pickup window runs simultaneously, capturing any LeadManaging records modified or created during the migration window. All operations are logged to an audit trail. If reconciliation detects missing records or data integrity issues, FlitStack can execute a one-click rollback that removes migrated records from Nutshell without affecting your LeadManaging source. You switch your team to Nutshell at the agreed go-live time.

Most LeadManaging to Nutshell migrations complete within 48–72 hours for under 25,000 total records. Migrations with 25,000–100,000 records, multiple custom fields, or complex deal-to-person associations extend to 5–8 days. The longest planning step is usually creating Nutshell custom fields and configuring pipelines before data starts moving — that work runs in parallel with your team's data cleanup review and does not add to the migration clock.
