Overview
Moving from YetiForce CRM to Mailchimp is a scope reduction, not a lateral platform move. YetiForce is a full CRM-ERP hybrid with over 80 modules covering contacts, organizations, deals, projects, tickets, products, vendors, and services. Mailchimp is primarily an email marketing platform that added limited CRM features (Companies, Deals, Opportunities) under Intuit ownership. We migrate what aligns: Contacts to Audience members, Organizations to Companies, Leads to contacts with a Lead Source tag, and Potentials to Opportunities. We do not migrate Projects, Tickets, Products, Services, Vendors, or Users since Mailchimp has no equivalent data model. The Reports module was removed in YetiForce v4.4 and has no Mailchimp equivalent; we flag this gap during scoping. YetiForce's free Webservice Standard API lacks bulk endpoints, so we use CSV export for high-volume extraction supplemented by API-based validation passes. The GitHub repository was archived read-only in August 2025, raising long-term maintenance concerns we disclose during scoping.

Object mapping
Each row shows how a YetiForce CRM object lands in Mailchimp, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
YetiForce CRM
Contact
Mailchimp
Audience Member
1:1YetiForce Contacts map directly to Mailchimp Audience members. The primary key is email address, which serves as the unique identifier in Mailchimp. We extract contacts using YetiForce's CSV Export or API (with batch chunking due to the lack of bulk endpoints in Webservice Standard), deduplicate by email, and import via Mailchimp's Bulk API. Phone number, address, and custom field values migrate to Mailchimp contact fields or merge fields if the plan supports them. Contact status (active/inactive) maps to subscriber status in Mailchimp.
YetiForce CRM
Organization
Mailchimp
Company
1:1YetiForce Organization records map to Mailchimp Companies (available when Mailchimp CRM features are enabled on the account). Organization name maps to Company name, industry maps to Industry, website maps to Website, and address fields map to the Company address object. Organizations must be imported before Contacts if the customer wants contact-company associations, since the Company ID serves as the lookup key on the contact record. Mailchimp Companies are optional; if CRM features are not enabled, Organizations do not migrate.
YetiForce CRM
Lead
Mailchimp
Audience Member with Lead Source tag
1:1YetiForce Leads map to Mailchimp Audience members with a Lead_Source custom field or tag capturing the original lead source value. Lead status is preserved in a custom field or tag. Mailchimp does not have a separate Lead object equivalent to Salesforce's Lead-Contact split; all prospects live in the Audience. We tag Leads to distinguish them from Contacts during import, allowing segmentation in Mailchimp without requiring a separate CRM.
YetiForce CRM
Potential
Mailchimp
Opportunity
1:1YetiForce Potentials (deals) map to Mailchimp Opportunities when Mailchimp CRM features are enabled. Potential name maps to Opportunity title, amount maps to Opportunity value, close date maps to Expected Close Date, and sales stage maps to Pipeline stage. Potentials tied to an Organization require the Organization to be imported first so that the Company ID lookup is satisfied. Mailchimp Opportunities do not support custom fields in the same way as full CRMs; we map the most critical fields and store additional metadata in tags.
YetiForce CRM
User
Mailchimp
Mailchimp Team Member
1:1YetiForce Users cannot be migrated as user records since Mailchimp's team management model is entirely different. We resolve Users by email address against the destination Mailchimp account's team members list and flag any YetiForce Users without a corresponding Mailchimp account for the customer's admin to provision. Owner assignments on Contacts, Organizations, and Potentials map to Mailchimp Tags or custom fields if the destination Mailchimp account supports the CRM features.
YetiForce CRM
Custom Field (contact-level)
Mailchimp
Merge Field or Tag
lossyYetiForce contact-level custom fields map to Mailchimp merge fields (text, number, date, address, phone) for structured data, and to Tags for categorical data. Merge fields require configuration in Mailchimp before import; we create them via the Mailchimp API during the schema preparation phase. Fields with picklist values in YetiForce map to Mailchimp Tags or to a pre-configured custom interest group. Fields with no Mailchimp equivalent are flagged for the customer's admin to decide on disposition.
YetiForce CRM
Attachment
Mailchimp
Not migrated
lossyYetiForce file attachments stored in the file system do not migrate to Mailchimp because Mailchimp does not have a file attachment model on contact records. We extract attachment metadata (file name, linked record ID, upload date) and write it to a CSV inventory delivered alongside the migration. The customer's admin can re-attach relevant files manually post-migration if needed. PDF documents linked to Potentials or Organizations are included in the same inventory.
YetiForce CRM
Ticket
Mailchimp
Not migrated
lossyYetiForce Tickets have no Mailchimp equivalent. Mailchimp is an email marketing platform and does not include helpdesk functionality. Ticket data (title, status, priority, category, related contact and organization references) is extracted to a CSV inventory with a count of records and a field-by-field column listing. The customer's admin receives this inventory as a reference for rebuilding ticket context in a dedicated helpdesk platform if needed. We do not migrate ticket conversations as they require a ticketing system context.

Migration approach
Discovery and object audit
We audit the source YetiForce installation across all active modules (Contacts, Organizations, Leads, Potentials, Tickets, Projects, Products, Services, Vendors, Attachments) and produce a data inventory with record counts per module. We identify whether Webservice Standard or Webservice Premium is active (affecting API vs CSV extraction), confirm the YetiForce version, and note the Reports module status. We pair this with a Mailchimp account review: plan tier, whether CRM features (Companies, Opportunities) are enabled, existing merge fields, and audience structure. The discovery output is a written scope document listing migratable objects, non-migratable objects with CSV inventory commitment, and the extraction method (CSV export vs API) per module.
Schema preparation in Mailchimp
We configure the destination Mailchimp account before any data import. This includes creating the Audience (or selecting the existing audience to receive migrated contacts), defining merge fields that map to YetiForce custom fields, setting up tags for Lead Source segmentation and custom field categorical values, enabling Companies and Opportunities in Mailchimp CRM if the plan supports it, and creating pipeline stages in Mailchimp that map to YetiForce Potential stages. Tags and groups replace many custom fields that have no structured field equivalent in Mailchimp.
Data extraction and deduplication
We extract data from YetiForce using CSV Export per module (Contacts, Organizations, Leads, Potentials) due to the lack of bulk API endpoints in Webservice Standard. For each module, we run a deduplication pass on email address (the primary key for Mailchimp contacts), identifying records with duplicate emails where the most complete or most recently updated record wins. We flag records with missing email addresses in a separate reconciliation queue; these contacts require email address recovery or manual entry before import can proceed. Attachments, Tickets, Projects, Products, Services, and Vendors are extracted to CSV inventories without import into Mailchimp.
Sandbox migration and tag mapping validation
We run a test import into a Mailchimp test audience using a subset of records (typically 500-1,000 contacts) to validate tag mapping, merge field population, and deduplication behavior. The customer's marketing lead spot-checks 25-50 contacts against the YetiForce source to confirm accuracy. Tag names derived from YetiForce picklist values are reviewed for readability and segmentation utility in Mailchimp. Any merge field type corrections (text vs number vs date) and tag naming adjustments happen here before the full production migration begins.
Production migration in dependency order
We run the production migration in record-dependency order: Organizations (to Companies first if CRM features are enabled), then Contacts (to Audience members with Company association resolved), then Leads (tagged as prospects), then Potentials (to Opportunities with Organization/Company lookup resolved). Each phase emits a row-count reconciliation report. After each phase, we run a Mailchimp API validation pass to confirm the record landed with the correct field values. Deduplication is enforced at the Contact and Lead import phases using email as the unique key.
Cutover, validation, and non-migratable data handoff
We freeze YetiForce writes during the cutover window and run a final delta pass for any records modified during migration. We deliver the CSV inventories for non-migratable objects (Tickets, Projects, Products, Services, Vendors, Attachments) with record counts and field-level listings. We validate the final Mailchimp audience record count against the extracted Contact count and resolve any discrepancies. We do not migrate YetiForce Workflows or automations to Mailchimp Customer Journeys as they are structurally different; we deliver a written list of active YetiForce automations for the customer's admin to evaluate for rebuilding in Mailchimp.
