Overview

What this migration involves

Affinity Fieldreach models its CRM around Persons, Organizations, Opportunities, and a rich set of relationship-strength indicators designed for venture capital and private equity deal-sourcing workflows. Nutshell uses a simpler three-entity model: Contacts (People), Accounts (Companies), and Leads, with pipeline stages tracked as Milestones within a single pipeline view. The migration carries every standard Affinity Fieldreach object into its Nutshell equivalent — Persons map to Contacts, Organizations map to Accounts, Opportunities map to Leads — while Affinity's custom fields migrate as Nutshell custom fields on the corresponding entity. Affinity relationship-strength scores have no Nutshell equivalent and are preserved as a read-only custom field for reference. FlitStack sequences the migration using Affinity's REST API (v1 endpoint at api.affinity.co) and Nutshell's JSON-RPC API (app.nutshell.com/api/v1/json), respecting both platforms' rate limits during extraction and load. Workflows, automations, and webhooks in Affinity Fieldreach do not migrate — FlitStack exports those definitions as a structured JSON file so your Nutshell admin can rebuild them in Nutshell's automation tools. A delta-pickup window of 24–48 hours captures any Affinity records modified during the cutover window.

Why teams make this switch

Two sides of the same decision

Leaving

Affinity Fieldreach

What's pushing teams away

  • Per-user pricing becomes expensive to scale as the team grows, with many forced premium features that do not justify the cost increase at Advanced and Enterprise tiers.
  • Document management is poor and does not integrate well with external document storage systems, creating friction for deal teams that rely on data rooms.
  • The configurable UI can feel overwhelming for new users due to the number of variables and interaction points across the platform.
  • Limited third-party integrations compared to mainstream CRMs, causing data silos between Affinity and other tools in the investment workflow.

Choosing

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 Affinity Fieldreach objects map to Nutshell

Each row shows how a Affinity Fieldreach 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.

Affinity Fieldreach

Person

maps to

Nutshell

Contact (People)

1:1
Fully supported

Affinity Person maps 1:1 to Nutshell Contact (internally called 'People' in the UI, 'Contact' in the API). FlitStack preserves the Person's original create date as a custom datetime field since Nutshell's createdate is set at migration time. All standard Person fields (name, email, phone, title, address) map directly.

Affinity Fieldreach

Organization

maps to

Nutshell

Account (Company)

1:1
Fully supported

Affinity Organization maps 1:1 to Nutshell Account (called 'Company' in the Nutshell UI, 'Account' in the API). Organization name, domain/website, industry, and employee count fields map directly. Nutshell's Account API field name is 'name' for company name — FlitStack resolves this during the field mapping phase. Parent-child organization hierarchies in Affinity map to Nutshell's parent Account field if configured.

Affinity Fieldreach

Opportunity

maps to

Nutshell

Lead

1:1
Fully supported

Affinity Opportunity maps to Nutshell Lead, not to a deal or opportunity object — Nutshell does not have a separate Opportunity object at the CRM level. Deal amount, expected close date, and deal name migrate as Lead custom fields in Nutshell. Affinity's opportunity stage values are mapped to Nutshell's Milestone (stage) values; if multiple Affinity pipelines exist, FlitStack maps them to a single Nutshell pipeline with stage filtering handled via a Pipeline custom field on the Lead record.

Affinity Fieldreach

Custom Field (Person-level)

maps to

Nutshell

Custom Field (Contact)

1:1
Fully supported

Affinity global custom fields at the Person level migrate to Nutshell Contact custom fields. FlitStack creates the Nutshell custom field using the same field type (text, number, date, picklist) inferred from the Affinity field definition. Multi-select picklist fields in Affinity become Nutshell multi-value custom fields where supported, or comma-separated text as a fallback.

Affinity Fieldreach

Custom Field (Organization-level)

maps to

Nutshell

Custom Field (Account)

1:1
Fully supported

Affinity Organization custom fields map to Nutshell Account custom fields. The same type-inference logic applies: text to text, number to number, date to date, picklist to picklist. Nutshell's custom field creation API requires the field key name — FlitStack generates a URL-safe key from the Affinity field label (e.g., 'Customer Tier' becomes 'customer_tier').

Affinity Fieldreach

Custom Field (Opportunity-level)

maps to

Nutshell

Custom Field (Lead)

1:1
Fully supported

Affinity Opportunity custom fields map to Nutshell Lead custom fields. Because Nutshell Lead is the target for all opportunity data, opportunity-level custom fields are appended to the Lead record alongside the transformed deal amount and close date fields. FlitStack surfaces the full list of Affinity opportunity custom fields in the pre-migration mapping plan.

Affinity Fieldreach

Interaction

maps to

Nutshell

Activity

1:1
Fully supported

Affinity Interactions (calls, emails, meetings logged against a Person or Organization) map to Nutshell Activities. Each Interaction type (call, email, meeting) maps to the corresponding Nutshell Activity type. Original timestamps and owner assignment are preserved. Affinity Interaction notes content migrates as the Activity description field in Nutshell.

Affinity Fieldreach

Note

maps to

Nutshell

Note

1:1
Fully supported

Affinity Notes attached to Persons, Organizations, or Opportunities map to Nutshell Notes. The note body, create date, and owning user are preserved. Nutshell Notes are linked to a parent entity (Contact, Account, or Lead) via the standard Nutshell note association model.

Affinity Fieldreach

List

maps to

Nutshell

Tag

1:1
Fully supported

Affinity List entries (static lists of Persons or Organizations) map to Nutshell Tags. Each List name becomes a Tag name in Nutshell. If an Affinity List is dynamic (auto-populated by filter rules), FlitStack exports the list definition as a JSON specification so your Nutshell admin can recreate equivalent filtered views or static tag groups in Nutshell.

Affinity Fieldreach

Relationship Strength

maps to

Nutshell

Custom Field (Contact)

1:1
Fully supported

Affinity relationship_strength scores are unique to Affinity's deal-sourcing model and have no Nutshell equivalent. FlitStack migrates the relationship_strength numeric value as a read-only custom field (Relationship_Strength__c) on the Nutshell Contact record for historical reference. This field is not actively used in Nutshell workflows but preserves the data for audit purposes.

Affinity Fieldreach

Entity File

maps to

Nutshell

Attachment (Contact/Account)

1:1
Fully supported

Affinity Entity Files attached to Persons, Organizations, or Opportunities are re-uploaded to Nutshell as file attachments on the corresponding Contact, Account, or Lead record. Nutshell stores attachments inline with the record. File size limits in Nutshell apply — files exceeding 25MB are flagged in the migration report for manual handling.

Affinity Fieldreach

Webhook / Automation

maps to

Nutshell

Not Available

1:1
Fully supported

Affinity Fieldreach automations and webhooks do not have a direct Nutshell equivalent. FlitStack exports the automation definition as a structured JSON file including trigger conditions, action steps, and field references. Your Nutshell admin uses this export as a rebuild specification for Nutshell's built-in automation tools (sequences and workflow rules). The data migration does not include automation logic by design.

Pair-specific challenges

  • Affinity Opportunity objects have no direct Nutshell deal equivalent

    Nutshell uses Leads as its opportunity-tracking entity, but Lead records do not have native fields for deal amount, expected close date, or custom deal-stage probability. Affinity opportunities carry deal amounts, close dates, and pipeline-stage histories that Nutshell Lead records cannot store natively. FlitStack creates custom fields on the Nutshell Lead object (Deal_Amount__c, Expected_Close_Date__c, Pipeline_Name__c) to capture this data, and maps Affinity opportunity stages to Nutshell Milestone values. Teams that rely on Affinity's pipeline reporting by deal amount will need to rebuild those reports in Nutshell using the migrated custom fields as data sources.

  • Multi-pipeline Affinity setups must consolidate into Nutshell's single pipeline

    Affinity Fieldreach supports multiple independent deal pipelines, each with its own stage set. Nutshell uses a single pipeline per account with stage values managed as Milestones. Teams with two or more Affinity pipelines must decide how to consolidate: either map all stages into one Nutshell pipeline with stage names prefixed by the original pipeline name, or use a Nutshell custom field (Pipeline_Source__c) to tag which Affinity pipeline each Lead originated from. FlitStack surfaces this decision in the pre-migration planning step and applies whichever consolidation rule your team selects before the full migration runs.

  • Affinity API rate limits on find requests affect extraction speed

    Affinity's API (api.affinity.co) rate limits find queries, particularly non-stub responses on List and Person queries. For large Affinity databases (50,000+ records), the extraction phase may require request throttling and pagination handling that extends the data pull timeline. FlitStack monitors 429 Too Many Requests responses and implements exponential backoff automatically. The Nutshell API similarly rate-limits find requests with non-stub responses. FlitStack coordinates throttling across both APIs to maximize throughput while avoiding rate-limit errors.

  • Relationship strength scores have no operational role in Nutshell

    Affinity's relationship_strength field is calculated from Interaction frequency and organizational network data — it is a proprietary metric with no Nutshell equivalent. FlitStack migrates the numeric value as a read-only custom field on the Nutshell Contact record. However, this field has no meaning inside Nutshell's workflow or reporting engine. Teams that built Affinity automations or reports around relationship_strength will need to either define a new Nutshell-based scoring model or accept that this metric is preserved for historical reference only.

  • Dynamic Affinity Lists cannot be migrated as live filters

    Affinity List entries can be static (manually added) or dynamic (auto-populated by filter rules against Affinity's Person or Organization fields). Nutshell Tags are static assignments — there is no native dynamic-list equivalent in Nutshell at the CRM level. FlitStack migrates the snapshot membership of dynamic lists (the records that matched at the time of migration) as Nutshell Tags. The filter logic itself is exported as a JSON specification so your Nutshell admin can recreate equivalent filtered Contact or Account views manually. Dynamic list logic is not automatically transferable between platforms.

Migration approach

Six steps for a successful Affinity Fieldreach to Nutshell data migration

  1. Inventory Affinity entities and custom field definitions

    FlitStack connects to the Affinity API using credentials scoped to read access. We enumerate all Person, Organization, Opportunity, Interaction, Note, and List records, plus all global custom field definitions including field type, required flags, and pick-list values. This inventory produces a schema map that is the basis for the Nutshell custom field creation plan. We also identify any Affinity automations and webhooks so their definitions can be exported as a rebuild reference before data moves.

  2. Create Nutshell custom fields and prepare the schema

    Before data is loaded, FlitStack creates all required Nutshell custom fields on the Contact, Account, and Lead objects using the Nutshell API. This includes the deal amount field, expected close date field, pipeline source tag field, original create date fields, and any Affinity custom fields that lack direct Nutshell equivalents. If multiple Affinity pipelines exist, we coordinate with your team to confirm the consolidation strategy and apply the pipeline tagging rule before any Lead records are created.

  3. Run a sample migration with field-level diff

    A representative slice of records — typically 100–500 spanning Contacts, Accounts, Leads, and a sample of Activities — migrates first. FlitStack generates a field-level diff comparing source Affinity values against the migrated Nutshell records so your team can verify that Person name fields, Organization domain mappings, Opportunity stage-to-Milestone value mapping, and custom field translations all look correct before the full run commits. Owner resolution (email-to-Nutshell-user matching) is validated in this phase, and any unmatched owners are flagged for your team to resolve.

  4. Execute the full migration with owner resolution and relationship preservation

    The full data set migrates in dependency order: Accounts first (since Contacts link to them via account_id), then Contacts, then Leads, then Activities and Notes. Affinity Lists are translated to Nutshell Tags and applied to the corresponding Contact or Account records at this stage. Entity file attachments are re-uploaded to Nutshell as record attachments. Owner assignment resolves Affinity owner_id values to Nutshell user IDs by email match. Any records that fail validation (missing required fields, unresolved lookups) are collected in an exception report for your team to review before the delta phase begins.

  5. Delta-pickup window and final audit

    A 24–48 hour delta window captures any Affinity records created or modified during the cutover period. FlitStack re-runs the migration delta against Nutshell using source_system_id matching to avoid duplicates. After the delta phase closes, FlitStack generates a final audit log showing record counts by entity type, any records that could not be migrated, and the total delta volume absorbed. One-click rollback is available within 72 hours of go-live if reconciliation reveals unexpected gaps in the migrated data.
