Overview
Migrating from Composity CRM to Nutshell is a platform simplification migration: Composity is a Bulgarian-origin all-in-one ERP/CRM combining CRM, inventory, accounting, and production modules, while Nutshell is a US-based CRM focused on SMB sales teams with unlimited contacts, built-in email sequences, and a documented JSON-RPC and REST API. Composity has no publicly documented API, so we extract via manual CSV exports or the platform's built-in export functionality, then ingest into Nutshell using its documented API endpoints with batch chunking and owner email resolution. Production, Projects, and Inventory modules from Composity have no native Nutshell equivalent; we deliver a written note flagging each as requiring manual recreation or a custom object strategy. Nutshell's per-user pricing ($19-$79 per month) versus Composity's per-tenant annual pricing removes the account-count ceiling that constrained growth on Composity Lite. We do not migrate Composity Workflows, Sequences, or automations; these require rebuild in Nutshell's Automation rules post-migration.

Object mapping
Each row shows how a Composity 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.
Composity CRM
Account
Nutshell
Company
1:1Composity Accounts map directly to Nutshell Companies. The Account name, address fields, industry, and status migrate as typed Company fields. Any custom properties defined in Composity's Custom Data module reverse-engineered during scoping map to Nutshell custom fields on Company. The Company record is created first so that Contact imports can resolve the Company lookup immediately.
Composity CRM
Contact
Nutshell
Person
1:1Composity Contacts map to Nutshell People. First name, last name, email, phone, title, and role migrate as typed Person fields. The Account-to-Contact relationship in Composity becomes the Person-to-Company relationship in Nutshell at migration time. Any custom contact fields from Composity's Custom Data module map to Nutshell custom fields on Person.
Composity CRM
Lead
Nutshell
Lead
1:1Composity Leads from the Campaign & Lead Management module map to Nutshell Leads with status, source, and qualification data preserved. Lead status values are mapped to Nutshell's Lead Status picklist. Composity's custom lead scoring fields map to a Nutshell custom numeric field for post-migration use.
Composity CRM
Opportunity / Deal
Nutshell
Deal
1:1Composity Opportunities and Deals from the Sales submodule map to Nutshell Deals. Deal name, value, stage, and expected close date migrate. Composity stage names are user-configurable per organization; we map each custom stage to a Nutshell Deal status value during scoping. Owner assignments on Deals migrate by resolving Composity owner email to Nutshell User.
Composity CRM
Pipeline Stages
Nutshell
Deal Status Values
lossyComposity's custom pipeline stages (defined in CRM settings) are exported as stage name and order pairs. We recreate them as Nutshell Deal status values during migration setup, preserving stage order and win/loss flags. Loss reason fields from Composity custom properties map to Nutshell Deal loss reason where supported.
Composity CRM
Product / SKU
Nutshell
Product
1:1Composity product catalog entries with name, SKU, price, and description map to Nutshell Products. Product-to-quote associations preserve through the Product reference on the imported Quote. Custom pricing rules or tiered pricing from Composity require manual configuration in Nutshell's Product pricing rules post-migration.
Composity CRM
Quote / Sales Order
Nutshell
Quote
1:1Composity Quotes and Sales Orders from the Sales module map to Nutshell Quotes. Line items, tax codes, and totals migrate. Partially settled invoices require balance carry-forward notation in a custom Quote field since Nutshell Quotes are linked to Deals rather than invoiced directly. Nutshell's built-in Quoting tool can regenerate finalized quotes from Deal data post-migration.
Composity CRM
Invoice
Nutshell
Custom Field + Note
1:1Composity Invoices (with line items, payment status, and totals) have no direct Nutshell object. We import invoice headers and totals as a Note attached to the related Deal, with payment status and outstanding balance preserved in custom Deal fields. Fully paid invoices migrate as closed Notes; partially paid invoices are flagged with a reconciliation note for the customer's accounting team.
Composity CRM
Activity (Call, Email, Meeting, Note)
Nutshell
Activity (Call, Email, Meeting, Note)
1:1Composity activities logged against Contacts and Accounts map to Nutshell Activities. Activity type, date, description, and linked record migrate. Call disposition and duration from Composity call logs map to Nutshell custom fields on the Activity record. Nutshell's timeline view consolidates calls, emails, meetings, and notes per Person and Company record. We preserve activity ordering by setting the Nutshell Activity date to the original Composity timestamp.
Composity CRM
User / Owner
Nutshell
User
1:1Composity Users with login credentials, roles, and permissions are matched to Nutshell Users by email address. Owner assignments on Contacts, Accounts, and Deals migrate by resolving the Composity owner reference to the Nutshell User ID. Any Composity Owner without a matching Nutshell User goes to a reconciliation queue for the customer's admin to provision the account before record import resumes.
Composity CRM
Custom Data Fields
Nutshell
Custom Fields
lossyComposity custom fields defined in the Custom Data module and applied to any object are reverse-engineered during scoping. We create equivalent Nutshell custom fields on the corresponding object (Company, Person, Deal, Lead, Activity) before migration begins. Field type mapping is validated: text to text, number to number, date to date, picklist to picklist. Multi-select picklists in Composity map to Nutshell multi-select custom fields.
Composity CRM
Document (File Attachment)
Nutshell
File Attachment
1:1Composity Document Storage exports files individually (no bulk download). We build a file inventory during discovery, download each file in parallel where possible, and reattach to the correct Nutshell record using filename or metadata matching. File upload dates and uploader metadata migrate as Note content. This is a manual-heavy step; large document inventories (hundreds of files) extend the migration timeline and are flagged during scoping.

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.
Composity CRM gotchas
Account count tier limits constrain migration scope
No publicly documented API for automated extraction
Production module has no CRM equivalent at most destinations
Module activation state affects what data exists
Documents exported as individual files with no bulk download
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 module audit
We audit the Composity tenant for active modules (CRM, Production, Projects, Inventory, Accounting), record counts per object, custom field definitions in the Custom Data module, document inventory in Document Storage, and current Composity plan tier. We also identify any Composity Owner records that must map to Nutshell Users. The discovery output is a written scope document listing every object that will migrate, every object that requires a custom object strategy, and the Composity export checklist that the customer completes to deliver source data.
Custom field schema recreation in Nutshell
Before any data moves, we create all Nutshell custom fields that correspond to Composity custom fields. We reverse-engineer the Composity field schema from the export, map each field to a Nutshell field type (text, number, date, picklist, multi-select), and create the fields on the correct Nutshell object (Company, Person, Deal, Lead, Activity). If Composity's Production or Projects modules are active and the customer wants to preserve that data, we design a custom object schema in Nutshell to hold it.
Composity data extraction and validation
The customer follows the Composity export checklist, downloading CSV exports for each active module (Accounts, Contacts, Leads, Deals, Products, Invoices, Activities). We validate each export for completeness (record count, required fields populated, no truncation) before building the ingest. If any export is incomplete or returns fewer records than expected, we request a re-export from Composity before proceeding. This step is the longest in the project because Composity has no API and exports must be run manually in the platform UI.
Owner and user reconciliation
We extract every distinct Composity Owner referenced on Accounts, Contacts, Deals, and Activities and match by email against the Nutshell destination's User table. Any Composity Owner without a matching Nutshell User goes to a reconciliation queue. The customer's admin provisions missing Nutshell User accounts before record import resumes. Owner resolution must be complete before Accounts, Contacts, and Deals can be imported because OwnerId is a required reference on those objects in Nutshell.
Production migration in dependency order
We run the Nutshell migration in record-dependency order: Companies (from Composity Accounts), People (from Composity Contacts with CompanyId resolved), Leads, Deals (with OwnerId and linked Company resolved), Products, Quotes, then Activities (calls, emails, meetings, notes via Nutshell API). Document files are attached after the parent record exists in Nutshell using filename or metadata matching. Each phase emits a row-count reconciliation report. Composity invoices are imported as Notes attached to Deals with payment status in custom fields; Production and Project records are delivered as a CSV with a mapping guide for the customer's custom object setup.
Cutover, validation, and automation rebuild handoff
We freeze Composity writes during cutover and run a final delta migration of any records modified during the migration window. We validate record counts, spot-check 20-30 records against Composity source data, and confirm that Activities are attached to the correct Person and Company. We deliver the automation and workflow inventory document (Composity has no native workflow engine, but any manual process notes or rule definitions from the Custom Data module are documented) to the customer's admin for rebuild in Nutshell's Automation rules. We support a 72-hour post-cutover window for reconciliation issues.
