Overview
Bolten CRM and Nutshell serve different market positions. Bolten targets Brazilian and LatAm sales teams through a white-label reseller model with per-Project billing, native WhatsApp integration, and AI-assisted autofill on inbound leads. Nutshell targets US and international SMBs with per-user pricing, unlimited contacts on all paid tiers, a documented REST API, and a built-in Import2 partnership for migrations from supported platforms. Moving from Bolten to Nutshell requires resolving three structural differences: Bolten's free-text Kanban stage names map to Nutshell's ordered stage picker, Bolten's per-Project pricing has no equivalent in Nutshell's per-user model, and Bolten's native WhatsApp conversation history (stored on Meta's infrastructure) cannot move into Nutshell. We export from Bolten using its available endpoints, clean and deduplicate the contact and deal records, build the Nutshell schema including custom fields and pipeline stages before import, and run reconciliation before cutover. We do not migrate WhatsApp message threads, AI suggestion history, Bolten Workflows, or Bolten Sequences as code.
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 Bolten 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.
Bolten CRM
Contact
Nutshell
Person (People)
1:1Bolten Contact records map to Nutshell People. The contact's name, primary email, phone numbers, address, and assigned tags transfer directly. Custom fields on the Contact object map to Nutshell custom fields on People; we pre-create Nutshell custom fields with matching types (text, number, date, dropdown, multi-select) before import so field mapping is type-compatible from the first load.
Bolten CRM
Lead
Nutshell
Lead
1:1Bolten Lead records (separate from Contacts in Bolten) map directly to Nutshell Leads with lifecycle status, source campaign attribution, and owner assignment preserved. Lead source and owner email resolve to the Nutshell user by email match during import. Leads and People are managed separately in both platforms, so no split logic is required.
Bolten CRM
Deal (Kanban Pipeline)
Nutshell
Opportunity
lossyBolten Kanban Deals map to Nutshell Opportunities. The most migration-critical step is stage ordering: Bolten uses free-text stage names with no enforced ordinal in the API, while Nutshell uses a configured stage picker with explicit ordering. We ask the customer to confirm the intended stage sequence during scoping, write the ordinal position explicitly into Nutshell during schema setup, and map Bolten stage names to Nutshell stage values by that confirmed order. Deal value, close date, and owner assignment transfer directly.
Bolten CRM
Deal Stage
Nutshell
Opportunity Stage
lossyEach Bolten Kanban pipeline becomes a Nutshell pipeline with ordered stage values. We configure Nutshell stages before migration with the customer's confirmed stage names and sequence. Stage probability percentages (if configured in Bolten) transfer to Nutshell's stage probability settings.
Bolten CRM
Task
Nutshell
Task
1:1Bolten Tasks migrate to Nutshell Tasks with assignee, due date, status, and linked contact or deal preserved. Recurring task rules in Bolten do not transfer; we flag them in the handoff document for the customer's admin to rebuild in Nutshell's task automation.
Bolten CRM
Activity Log
Nutshell
Activity
1:1Bolten activity audit logs (every record change, assignment, and stage move) transfer as Nutshell Activity records attached to the relevant People, Company, or Opportunity. Each activity carries the timestamp and operator from Bolten's audit trail so the full change history is preserved in the destination timeline.
Bolten CRM
Custom Field
Nutshell
Custom Field
lossyBolten custom fields per object (text, number, date, dropdown, multi-select) map to Nutshell custom fields on the equivalent object. We pre-create the destination custom fields before import, converting Bolten field types to Nutshell-supported types. Any Bolten custom field with no direct Nutshell equivalent is flagged during scoping with a recommended handling approach.
Bolten CRM
User / Assignee
Nutshell
User
1:1Bolten users are identified by email and name. We map Bolten user emails to Nutshell user emails during import. Suspended or inactive Bolten users are flagged for remapping to active Nutshell users so that no record is assigned to a deactivated destination user.
Bolten CRM
Tag
Nutshell
Tag
1:1Bolten flat-label tags applied to contacts and deals transfer as Nutshell tags with the tagging relationship per record preserved. Tags are string values in both platforms, so no type conversion is required.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Bolten CRM gotchas
Per-Project billing does not scale like per-seat models
WhatsApp message history lives on Meta's infrastructure
Kanban stage names are free-text, not schema-enumerated
AI autofill data may not reflect corrected final field values
Nutshell gotchas
Contact tier limits enforced on import
No bulk API endpoint requires paginated extraction
Email sequences not exportable via API
Foundation plan disables key sales features
Pair-specific challenges
Migration approach
Discovery and Bolten environment audit
We audit the source Bolten environment: active Projects, record counts per object (Contacts, Leads, Deals, Tasks, Activities), custom field configurations per object, Kanban pipeline and stage names, user and assignee list, and any tagged data. We also confirm which Bolten add-ons are active (AI Agent, Conversions, Social) so we can map the equivalent data types in Nutshell. This audit produces a written migration scope that the customer reviews and approves before we begin extraction.
Stage order confirmation and schema setup in Nutshell
We ask the customer to confirm the intended stage sequence for each Bolten Kanban pipeline before any data is extracted. With confirmed stage order in hand, we create the equivalent Nutshell pipelines with ordered stage values and stage probabilities. We also pre-create any custom fields required on People, Companies, Leads, and Opportunities so the destination schema is complete before the first import batch runs.
Data extraction and deduplication
We extract records from Bolten using available endpoints and load them into our staging environment. We run deduplication on contacts (by email address) and companies (by domain or name) to identify and resolve duplicates before import. Any Bolten record with a null primary identifier is flagged and resolved with the customer before it enters the import queue. AI autofill-suggested values that differ from the final user-confirmed value are resolved in favor of the final confirmed value.
User and assignee reconciliation
We extract every distinct Bolten user and assignee referenced on contacts, deals, tasks, and activities. We match each by email against the Nutshell destination's user list. Bolten users without a matching Nutshell user go to a reconciliation queue for the customer's admin to provision or map to an existing Nutshell user before record import proceeds. Owner assignments cannot resolve without an active Nutshell user.
Staging migration and reconciliation
We run a full migration into a Nutshell test environment using production-like record volume. The customer reconciles record counts across all objects, spot-checks 20-30 records against Bolten source data, and signs off the mapping and schema before production migration begins. Any field mapping corrections or stage sequence adjustments happen in this phase.
Production migration in dependency order
We run production migration in record-dependency order: Users (validated from reconciliation), Companies (if separate from People), People, Leads, Opportunities with stage assignments and owner lookups resolved, Tasks, and Activity history. Each phase emits a row-count reconciliation report before the next phase begins. We freeze Bolten write access during the final delta window to capture any records modified during migration.
