Overview
Fergus is a field-service management platform built for trade businesses — it tracks customers, sites, quotes, jobs, invoices, staff, and materials with its own workflow automation layer. Zoho CRM is a sales-and-service CRM with Leads, Contacts, Accounts, Deals, and Quotes modules plus Blueprint for process automation. The two platforms share almost no architectural DNA: Fergus organizes around jobs and phases, Zoho organizes around leads and deal stages. FlitStack AI migrates every migratable record — customers to Leads or Contacts, quotes to Zoho Quotes, jobs to Deals with phase data stored in custom fields — while honestly disclosing that Fergus automations (status-change triggers, job-phase notifications, approval routing) have no Zoho equivalent and must be rebuilt from scratch. We use the Fergus REST API (100 req/min rate limit, batched across windows) to extract data, normalize pick-list values, and load into Zoho via the Bulk API with per-module validation. Attachments re-upload to Zoho Files, original create dates preserve as custom datetime fields, and owner resolution happens by email match against Zoho users before any records land.
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 Fergus 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.
Fergus
Customer
Zoho CRM
Lead / Contact
1:manyFergus customers who are prospects or have not yet had a job booked become Zoho Leads. Active customers with a signed quote or completed job convert to Contacts linked to an Account. We use the existence of a Fergus Quote or Job record as the split criterion so no record lands in the wrong module.
Fergus
Customer (B2B)
Zoho CRM
Account + Contact
1:1Fergus customers with a company name stored become Zoho Accounts with the company name as Account Name, and the customer contact becomes a Contact linked to that Account via Account Name lookup. If Fergus stores multiple contacts per company, the primary contact links; additional contacts import as separate Contact records.
Fergus
Site
Zoho CRM
Custom Module: Job Sites
1:1Fergus Sites have no Zoho native equivalent — we create a custom 'Job Sites' module with fields for Site Name, Address, Site Contact Name, Site Contact Phone, and a lookup to the parent Account or Contact. Each Fergus Site ID is preserved as an external ID on the custom module record.
Fergus
Quote
Zoho CRM
Quote
1:1Fergus quotes map to Zoho Quotes with Quote Number, Subject, Account (via lookup), Contact, Valid Till date, and line items migrated as Quote Items sub-form rows. Fergus quote status (Draft, Sent, Approved, Declined) maps via value-mapping to Zoho Quote Status pick-list.
Fergus
Quote Item (materials/labour/markup)
Zoho CRM
Quote Item Sub-form
1:1Fergus quote line items (product/service name, quantity, unit price, cost, margin %) become Zoho Quote Item rows. Margin and cost are stored as custom number fields on the sub-form row since Zoho Quote Items do not natively track cost or margin. Markup percentage is recalculated from the migrated cost and unit price fields.
Fergus
Job
Zoho CRM
Deal
1:1Fergus Jobs map to Zoho Deals. Job Name becomes Deal Name, expected revenue or quote value becomes Deal Amount, and Fergus Job Status (Scheduled, In Progress, On Hold, Complete, Invoiced) maps via value_mapping to Zoho Deal Stage pick-list values. The original Fergus Job Number is preserved as Source_Job_Number__c on the Deal for reconciliation.
Fergus
Job Phase
Zoho CRM
Custom Pick-list: Job_Phase__c
1:1Fergus tracks job progress through phases (e.g., Scheduled, En Route, On Site, Parts Ordered, Complete). Zoho has no native phase concept on Deals, so we create a custom pick-list field Job_Phase__c and map each Fergus phase name to a matching pick-list value. Phase-entered timestamps are stored as custom datetime fields per phase.
Fergus
Job Assignment (Staff)
Zoho CRM
Custom Lookup: Assigned_Staff__c on Deal
1:1Fergus staff assigned to jobs have no direct Zoho equivalent since Zoho Users are CRM administrators and salespeople. We create a custom lookup field Assigned_Staff__c on the Deal that resolves by email match to existing Zoho Contacts representing staff members. Unresolved staff are flagged for manual assignment before go-live.
Fergus
Invoice
Zoho CRM
Not Migrated
1:1Fergus invoices do not migrate because Zoho CRM has no native invoicing module. Companies that need invoice history in Zoho should use Zoho Invoice as a separate application. We export Fergus invoice records (invoice number, date, amount, line items, payment status) as a CSV reference file that can be imported into Zoho Invoice manually or via a separate Zoho Invoice data migration. Invoice attachments re-upload as Zoho Files linked to the exported invoice reference.
Fergus
Activity (calls, emails, notes)
Zoho CRM
Task / Note
1:1Fergus activity log entries (call summaries, email bodies, internal notes attached to jobs) migrate as Zoho Tasks with Subject, Description, Related To (linked to the corresponding Deal), Owner (resolved by email), and original timestamps. Fergus note attachments re-upload to Zoho Files.
Fergus
Attachment / File
Zoho CRM
File
1:1Fergus file attachments on quotes and jobs re-upload to Zoho Files, linked to the corresponding Quote or Deal record. Files are downloaded from Fergus, uploaded to Zoho Files with the original filename and a reference to the source Fergus record ID preserved in a custom field.
Fergus
Pricing Tier
Zoho CRM
Custom Pick-list: Customer_Pricing_Tier__c
1:1Fergus pricing tiers (assigned per customer for material pricing) have no Zoho equivalent. We create a custom pick-list field on the Account or Contact record and map each Fergus pricing tier name to a pick-list value. The tier determines material pricing in Zoho via lookup formulas or manual reference.
Fergus
Staff / Employee
Zoho CRM
Contact (with Role designation) / Inactive User
1:1Fergus staff who are also CRM users import as inactive Zoho Users with their email and name, linked to Contact records for field assignment purposes. Non-CRM staff are imported as Contacts with a Staff_Role__c custom pick-list field. This ensures job assignments can still reference staff without consuming Zoho user licenses.
Fergus
Custom Field (Fergus-specific)
Zoho CRM
Custom Field on respective module
1:1Fergus custom fields on any module (e.g., custom properties on Jobs for trade-specific data) migrate to Zoho custom fields on the corresponding module. The Fergus field data type is matched to the nearest Zoho field type — multi-select pick-lists, checkboxes, and numeric fields all map with type-aware conversion.

Zoho CRM gotchas
API access requires Professional tier or above
Subform fields do not export cleanly via CSV
API credit consumption is non-linear
Export download links expire in 7 days
Owner (User) assignments require pre-mapped user IDs
Pair-specific challenges
Migration approach
Extract Fergus data model via REST API with rate-limit-aware batching
FlitStack AI connects to the Fergus REST API using your API key, discovers the full object and field schema, and extracts all migratable records (customers, accounts, sites, quotes, jobs, staff, activities) in rate-limit-compliant batches. The 100 req/min limit is respected via timed windowing across all endpoints. We pull field metadata first to identify custom fields, then extract records in dependency order (parent objects before child objects). The extracted data is staged in a FlitStack-managed environment for transformation and validation before any Zoho load begins.
Build Zoho custom modules, fields, and pick-list values
Before any records load, FlitStack AI creates the Zoho custom modules (Job Sites) and custom fields (Job_Phase__c, Material_Cost__c, Labour_Cost__c, Staff_Role__c, Source_Fergus_ID__c, Original_Create_Date__c, Customer_Pricing_Tier__c, Assigned_Staff__c) on the appropriate modules. Fergus pick-list values (job phases, quote statuses, customer statuses, staff roles) are pre-loaded into Zoho field configurations so incoming records will not be rejected on import. The custom Sales Process aligned to Fergus pipelines is also configured at this stage.
Resolve owner and staff mappings by email match
Fergus staff and customer owners are matched to Zoho users by email address. Matched staff are assigned as Deal owners or populate the Assigned_Staff__c lookup. Staff without Zoho user accounts are imported as Contacts with Staff_Role__c designated. Unmatched owners are flagged in the mapping document with a fallback assignment to the Zoho admin user — your team reviews and redistributes before the full migration runs.
Run sample migration with field-level validation
A representative sample of 50–200 records (covering a mix of customers, quotes, jobs, and activities) migrates to Zoho in a test environment. FlitStack AI generates a field-level diff report comparing source values against destination field values for every mapped field. You verify pick-list value mapping accuracy, custom field population, Deal stage assignment, and owner resolution. Any mapping errors are corrected in the transformation logic and the sample re-runs until the diff is clean before the full migration proceeds.
Execute full migration with delta-pickup and rollback plan
The full dataset loads into Zoho via the Zoho Bulk API in dependency order: Accounts first, then Contacts, Job Sites, Quotes with line items, Deals with custom fields, and finally Tasks linked to Deals. A 48-hour delta-pickup window runs concurrently — any Fergus records created or modified during the migration window are captured in a second pass and merged into Zoho before go-live. An audit log records every record created, updated, or skipped. If reconciliation reveals discrepancies, one-click rollback reverts the Zoho environment to its pre-migration state.
