Overview
Moving from Sunbase Data to Zoho CRM is a structural migration constrained by Sunbase's lack of a documented REST API. Sunbase organizes data across separate modules (CRM, Projects, HR, Invoicing) with no unified export endpoint, so we coordinate with Sunbase's technical team to establish extraction via direct database access or module-level CSV exports. We preserve relationships between Deals and Projects, Work Orders and Employees, and Invoices and Clients by building a cross-module ID map during discovery. Zoho CRM's native Data Migration Wizard accepts CSV imports for its standard modules (Leads, Contacts, Accounts, Deals, Activities) and creates custom modules automatically for Sunbase objects without direct equivalents. Automation workflows, pipeline configurations, and custom object schema definitions do not migrate; we deliver a written inventory of Sunbase automation logic for the customer's admin to rebuild in Zoho Blueprint and workflow rules. Timeline runs six to twelve weeks depending on data volume and extraction method agreed during discovery.

Object mapping
Each row shows how a Sunbase Data object lands in Zoho CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Sunbase Data
Lead
Zoho CRM
Lead
1:1Sunbase Leads (captured via door-to-door forms, web capture, or manual entry) map directly to Zoho CRM Lead records. Lead source, status, and assignment data migrate as data fields. Some Sunbase lead fields are tied to automation workflows that cannot migrate; we document these as part of the automation inventory deliverable. The Zoho Data Migration Wizard auto-maps standard lead fields and prompts for custom field creation when it encounters unmapped columns.
Sunbase Data
Contact
Zoho CRM
Contact
1:1Sunbase Contact records (name, email, phone, address, and industry-specific fields depending on CRM module configuration) map to Zoho CRM Contact. We preserve all standard fields and map custom contact fields to Zoho custom fields created during the migration wizard phase. The customer provides a custom field manifest during scoping so field types match correctly.
Sunbase Data
Client
Zoho CRM
Account
1:1Sunbase Client records represent business entities (companies) that Sunbase distinguishes from individual Contacts. We map Client to Zoho CRM Account, preserving business name, address, and any client-level custom fields. Account becomes the parent of the related Contact records, establishing the Account-Contact hierarchy that Zoho CRM uses for organizational modeling.
Sunbase Data
Deal
Zoho CRM
Deal
1:1Sunbase Deals track the full sales cycle including proposals, quotes, and pipeline stages. We map Deal to Zoho CRM Deal, preserving deal values, stage history, and associated contacts. Pipeline stage names and deal statuses migrate as data values. Custom deal fields require explicit mapping against Zoho custom fields, and the customer provides the custom field manifest during scoping.
Sunbase Data
Project
Zoho CRM
Custom Module (Project)
1:1Sunbase Projects represent installation or job-site operations with no direct standard equivalent in Zoho CRM. We create a Zoho custom module named Projects (auto-detected from Projects_C.csv naming or manually mapped during wizard configuration) and migrate project metadata, status, budget tracking, and linked Work Orders as a unified record. Projects with multiple associated Work Order records are linked via Zoho lookup fields after both modules are created.
Sunbase Data
Work Order
Zoho CRM
Custom Module (Work Order)
1:1Sunbase Work Orders include permit info, task details, attachments, and system specifications. We create a Zoho custom module Work Orders linked to the Projects custom module via a lookup field. Employee assignments and scheduling data migrate as related records or custom fields. Attachments migrate as Zoho CRM file attachments linked to the Work Order record. Zoho's attachment limit and file size constraints apply per the target edition.
Sunbase Data
Invoice
Zoho CRM
Invoice
1:1Sunbase generated invoices including repeat invoices and financing-related billing map to Zoho CRM Invoice. We extract invoice line items, payment status, and linkage to the originating project or client. Historical paid invoices migrate with their status preserved. Zoho Invoice module supports custom fields so industry-specific billing data maps without truncation.
Sunbase Data
Employee
Zoho CRM
User or Custom Module (Employee)
1:1Sunbase Employee records include HR data, crew assignments, and role information. Zoho CRM Users represent licensed platform users; non-licensed employees who do not log into Zoho migrate to a custom Employee module with their HR data stored as fields. GPS location history is bulk-exported where available and mapped to a Zoho custom field or related record. The customer decides during scoping whether to provision employees as Zoho Users (if they need CRM access) or a custom HR module.
Sunbase Data
Appointment
Zoho CRM
Activity (Task / Event)
1:1Sunbase Appointments sync with Google Calendar and include customer-linked scheduling. We preserve appointment dates, times, assigned contacts, and status as Zoho CRM Event records for calendar-linked appointments or Task records for to-do style appointments. Calendar linkage itself is not transferable; appointments land in Zoho's activity timeline linked to the parent Contact or Account record. Recurring appointment patterns do not migrate as recurring definitions; they are resolved into individual Event records.
Sunbase Data
Document
Zoho CRM
Attachment (related to parent record)
1:1Documents include contracts, financing applications, and permits stored within Sunbase. We extract binary files and preserve file names, upload dates, and associations to the parent record (Contact, Deal, Project, Work Order). Each file is attached to its Zoho CRM record via the Attachments module. The Attachments folder must be zipped alongside CSV data files per Zoho's migration wizard structure, and individual file size limits apply per the target Zoho CRM edition.
Sunbase Data
Asset and Inventory
Zoho CRM
Custom Module (Asset/Inventory) or Product
1:manySunbase Asset and Inventory records track materials, equipment, and supplies across projects. Equipment and inventory items with SKU and pricing data map to Zoho CRM Product records if they appear in the sales quoting context. Standalone asset tracking records (without pricing context) map to a custom Asset module created during migration. Quantities, linked projects, and supplier information migrate as custom fields. Inventory levels at the time of migration are preserved as snapshot values rather than live inventory sync.
Sunbase Data
Custom Object
Zoho CRM
Custom Module
lossySunbase supports custom objects within its module system but provides no documented export schema for custom object definitions. We cannot guarantee complete migration of custom object definitions without a customer-provided manifest. We create Zoho custom modules for identified custom objects (using _C.csv naming if available) and migrate data values. The customer provides the custom object field manifest during scoping, including field names, types, and any picklist values, so Zoho custom fields are created with correct types before data import begins.

Migration approach
Discovery and extraction method confirmation
We audit the Sunbase Data account across all active modules (CRM, Projects, HR, Invoicing), identifying all record types, custom fields, automation rules, and pipeline configurations in use. We coordinate with Sunbase's technical team to confirm the available extraction method: direct database access or manual module-level CSV exports. We document the cross-module relationship map (Contact-to-Deal, Project-to-Work Order, Invoice-to-Client) that will guide relationship resolution at migration time. The discovery output is a written migration scope and extraction method confirmation. If direct database access is unavailable, we plan for manual export sequencing with a structured export template to maximize relationship data capture.
Custom field manifest and Zoho edition confirmation
The customer provides a custom field manifest for Sunbase objects, including field names, data types, and picklist values. We use this manifest to design the Zoho CRM target schema: custom fields in Zoho CRM for each Sunbase custom field, custom modules for Sunbase objects without standard Zoho equivalents (Projects, Work Orders, Assets), and lookup relationships between modules. We confirm the target Zoho edition (Professional minimum for custom fields, Enterprise if lookup relationships between custom modules are required) and create the Zoho schema in a Sandbox environment for validation before production migration.
Sandbox migration and schema validation
We run a full migration into a Zoho CRM Sandbox using a representative data sample. The customer reconciles record counts (Leads in, Contacts in, Accounts in, Deals in, Project records in, Work Order records in, Invoice records in), spot-checks 25-50 random records against the Sunbase source, and validates that custom fields landed in correctly-typed Zoho fields. The Zoho Data Migration Wizard's auto-mapping is reviewed for accuracy and any corrections to field mapping are applied before production migration. Schema corrections happen in Sandbox, not in production.
Data extraction and transformation
We execute the extraction method confirmed during discovery. If using direct database access, we extract each module's records and cross-module relationship IDs in parallel. If using manual CSV exports, we provide the customer with a structured export template per module that includes ID fields and relationship columns needed for relationship resolution. We transform all records into Zoho-compatible CSV format, applying the field mapping defined in scoping, resolving cross-module lookups using the relationship map built in discovery, and applying Zoho field type validation (date formats, picklist values, required fields).
Production migration in dependency order
We run production migration in record-dependency order. Accounts (from Sunbase Clients) are migrated first, followed by Contacts (with AccountId resolved), Leads, Deals (with AccountId and ContactId resolved), custom module records (Projects, Work Orders, Assets, Employees), and finally Invoices with project and client linkages. Documents migrate as Zoho attachments linked to their parent records. Each phase emits a row-count reconciliation report before the next phase begins. Zoho Data Migration Wizard auto-creates any custom modules not already provisioned, using _C.csv naming convention or manual module mapping.
Cutover, validation, and automation rebuild handoff
We freeze Sunbase writes during cutover and run a final delta migration of any records modified during the migration window. We deliver the automation inventory document listing every active Sunbase workflow and pipeline configuration with its trigger, conditions, actions, and a recommended Zoho Blueprint or workflow rule equivalent. We do not rebuild Sunbase workflows as Zoho workflows inside the migration scope. We support a one-week hypercare window where we resolve reconciliation issues raised by the customer's team. Post-migration admin configuration, training, and workflow rebuild are outside standard scope and available as separate engagements.
