Overview
Moving from Pro-Sales CRM to Nutshell is a consolidation migration for small sales teams that have outgrown Pro-Sales CRM's feature surface. Both platforms use a Company-Contact-Deal model with activity logging, but Pro-Sales CRM stores call dispositions and owner assignments as first-class fields, while Nutshell uses an Organization-Person-Deal structure with a built-in Scheduler, quoting tool, and AI chatbot in every paid plan. We resolve the owner-to-User mapping during scoping, migrate custom fields into Nutshell's custom field slots (subject to plan limits), and flag that file attachments do not migrate from Pro-Sales CRM because the source API does not expose a confirmed export path. Nutshell's free onboarding and 14-day trial do not include migration services, so teams rely on FlitStack AI to execute the data move while Nutshell's support team handles platform setup and configuration. Workflows, call routing rules, and dispositioning configurations in Pro-Sales CRM do not have direct Nutshell equivalents and are not migrated; we deliver a written inventory of these for the customer's admin to configure post-cutover.
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 Pro-Sales 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.
Pro-Sales CRM
Contact
Nutshell
Person
1:1Pro-Sales CRM Contact records map to Nutshell People. The Contact's name, email, phone, and company association migrate directly. The lifecycle stage property from Pro-Sales CRM maps to a custom field lifecycle_stage__c on the Nutshell Person record because Nutshell uses a lead status workflow rather than a lifecycle stage property. We preserve the original stage string for reporting continuity. Owner assignment from Pro-Sales CRM maps to the Nutshell Person owner via email lookup against Nutshell Users.
Pro-Sales CRM
Company
Nutshell
Organization
1:1Pro-Sales CRM Company records map to Nutshell Organizations. Address fields, industry, and company size migrate as typed Organization fields. The Organization record is created before any related Person records to satisfy Nutshell's organization-person lookup. Company records serve as the parent of migrated People records via the organization_id reference.
Pro-Sales CRM
Owner
Nutshell
User
1:1Pro-Sales CRM owner assignments on Contact, Company, and Deal records map to Nutshell Users by email match. Any Pro-Sales CRM owner without a matching Nutshell User is held in a reconciliation queue for the customer's admin to provision before record import begins. Owner is required on Person and Deal imports in Nutshell, so this step gates the production migration.
Pro-Sales CRM
Deal
Nutshell
Deal
1:1Pro-Sales CRM Deal records map to Nutshell Deals. The deal name, value (amount), close date, and stage name migrate directly. Pro-Sales CRM's custom stage names are mapped to Nutshell pipeline stages via a customer-defined mapping table built during discovery. The Pro-Sales CRM owner field maps to the Nutshell Deal owner via the User mapping above.
Pro-Sales CRM
Pipeline Stages
Nutshell
Pipeline Stages
lossyPro-Sales CRM allows custom stage names with per-stage probability weights. We extract the active stage configuration from the source account and create equivalent Nutshell pipeline stages before any Deal import. Stage probability percentages are mapped to Nutshell's stage probability field with rounding to Nutshell's supported granularity.
Pro-Sales CRM
Activities (calls, notes, tasks)
Nutshell
Activities
1:1Pro-Sales CRM activity records (call logs, notes, task completions) migrate to Nutshell Activities. We preserve the original timestamp to maintain the activity timeline ordering. Call disposition values from Pro-Sales CRM migrate as custom Activity fields in Nutshell. Date and timezone normalization is applied during staging because Pro-Sales CRM timestamps may use a different offset from the customer's Nutshell account timezone.
Pro-Sales CRM
Tags/Labels
Nutshell
Tags
1:1Tag assignments on Pro-Sales CRM records (Contacts, Companies, Deals) are extracted as string values and applied to the corresponding migrated Nutshell records (Person, Organization, Deal) after the base record import completes. We preserve tag strings exactly and do not normalize or deduplicate them; the customer decides whether to clean duplicate tags post-migration.
Pro-Sales CRM
Custom Properties
Nutshell
Custom Fields
lossyPro-Sales CRM custom fields on Contacts and Deals are recreated as Nutshell custom fields before migration. Nutshell's custom field limits vary by plan: Foundation allows 10, Pro allows 20, Power AI allows 30, and Enterprise allows more. During discovery we inventory all Pro-Sales CRM custom fields and map them to Nutshell equivalents within the target plan's limit. Fields exceeding the plan cap are flagged and the customer either upgrades the Nutshell plan or accepts that those fields will not migrate.

Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Pro-Sales CRM gotchas
Catalog name 'Pro-Sales CRM' is non-standard — vendor brands as SalesPro CRM
Add-on data migration and training fees add to year-one TCO
No documented public API
Per-user pricing scales linearly without enterprise discount tier publicly listed
Nutshell gotchas
Contact tier limits enforced on import

Foundation plan disables key sales features
Pair-specific challenges
Migration approach
Discovery and export feasibility check
We audit the source Pro-Sales CRM account: record counts for Contacts, Companies, Deals, Activities, and Tags; inventory of custom fields per object; pipeline and stage configuration; owner list; and any known attachment storage. We also attempt a test export via Pro-Sales CRM's available export mechanism (API or CSV) to confirm data completeness before scoping. We flag the thin API documentation for Pro-Sales CRM upfront so the customer understands any data completeness risks before we proceed.
Schema design and Nutshell plan validation
We design the destination schema in Nutshell: Organizations, People, Deals, custom fields, pipelines, and stage names. We validate that the target Nutshell plan's custom field limit accommodates the source custom field inventory. If the plan cap is insufficient, we present an upgrade option or an exclusion list. We also map the Pro-Sales CRM owner list against the Nutshell User list, identify any unmatched owners, and generate a provisioning request for the customer's admin.
Staging migration and reconciliation
We run a full migration into the customer's live Nutshell account using a staged subset of records. The customer's sales lead or admin spot-checks 20-30 random records (mix of Person, Organization, and Deal) against the source Pro-Sales CRM data, validates that stage names and owner assignments are correct, and signs off the mapping before production migration. Any field mapping corrections are applied here.
Owner reconciliation and User provisioning
We confirm that every Pro-Sales CRM owner has a matching Nutshell User. Owners without a match are listed with their Pro-Sales CRM email and record count. The customer's Nutshell admin provisions missing Users (or deactivates the Pro-Sales CRM owner in the source if the person has left). This step gates the production migration because Nutshell requires an owner on Person and Deal imports.
Production migration in dependency order
We run production migration in record-dependency order: Organizations (from Companies) first, then People (with organization_id resolved from the Organization import), Deals (with owner_id resolved from the User mapping and stage names mapped via the stage table), Activities (with timestamps normalized and linked to the correct Person, Organization, or Deal), and Tags (applied after base records are in place). Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, delta migration, and automation inventory handoff
We freeze Pro-Sales CRM writes during the cutover window, run a final delta migration for any records modified in the previous 24-48 hours, then mark Nutshell as the system of record. We deliver a written inventory of call routing rules, dispositioning configurations, and any Pro-Sales CRM automations that require rebuild in Nutshell's workflow engine or via a third-party integration. We support a five-day hypercare window for reconciliation issues. Post-migration admin rebuilds of workflows and call routing are outside standard scope and are handled separately.
