Overview

What this migration involves

BigChange is a field-service and job-management platform built around Jobs, Schedules, Quotes, and a mobile workforce layer. It has a CRM component (Contacts, Companies) but its core value lies in operational dispatch, technician scheduling, and asset tracking — not in sales pipeline management. Zoho CRM is a sales-focused CRM with Leads, Contacts, Accounts, Deals, Tasks, Events, and a rich Blueprint automation layer. When teams migrate from BigChange to Zoho CRM, they are typically doing one of two things: consolidating a standalone CRM that sat alongside BigChange, or moving customer and sales data out of BigChange while rebuilding field-service operations in Zoho Creator or a dedicated FSM tool. FlitStack AI migrates every record BigChange exposes via its DaaS API — Contacts, Companies, Quotes, and custom fields — into the corresponding Zoho CRM modules. Original create dates, owner assignments, and attachment references are preserved. Workflows, scheduling rules, and job-dispatch logic do not migrate; they must be rebuilt in Zoho Blueprint or Deluge scripts. The migration runs through Zoho's API using OAuth tokens, respecting per-edition API credit limits (5000 credits/day on Standard, scaling to 5,000,000 credits/day on Ultimate). A 24–48 hour delta-pickup window captures in-flight changes during cutover.

Why teams make this switch

Two sides of the same decision

Leaving

BigChange logo

BigChange

What's pushing teams away

  • Unclear pricing changes and awkward cost increases frustrate users; feedback is dismissed with claims improvements would take too long.
  • The platform is described as quick to upsell additional services but difficult to work with when trying to reduce costs or remove services.
  • Requests to scale back usage are met with delays and resistance, with some reviewers citing deceptive billing practices.
  • High costs for setting up quoting documents and system reliability issues — CRM systems failing on JobWatch and map view crashes on mobile — drive dissatisfaction.
  • Performance slows noticeably during evening hours, grinding to a halt during peak usage windows.

Choosing

Zoho CRM logo

Zoho CRM

What's pulling them in

  • Free tier is genuinely usable for up to 3 users with leads, pipeline management, and email tracking — no credit card required, making it easy to evaluate before committing.
  • Pricing undercuts Salesforce by 80–90% at equivalent feature tiers, with Enterprise plans offering capabilities that cost 3–4× more on competing platforms.
  • Deep ecosystem of 45+ integrated apps (Books, Desk, Creator, Campaigns) means companies already in the Zoho suite get native integrations without third-party connectors.
  • Highly customizable: custom modules, custom fields, Canvas drag-and-drop layouts, and Blueprint workflow automation without requiring developer resources.
  • Small-business reviewers highlight real-time team visibility, daily time savings of 60–90 minutes, and the ability to mold the CRM to any industry vertical.

Object mapping

How BigChange objects map to Zoho CRM

Each row shows how a BigChange 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.

BigChange

Person (Contact)

maps to

Zoho CRM

Contact

1:1
Fully supported

BigChange Persons map directly to Zoho CRM Contacts. The primary company link (stored as a company lookup in BigChange) migrates as a lookup to the corresponding Zoho Account. Persons without a linked company land as Contacts with no AccountId and are flagged for manual assignment.

BigChange

Person (Contact)

maps to

Zoho CRM

Lead

1:many
Fully supported

If BigChange stores pre-sales or inquiry records that are not yet active customers, those Persons split to Zoho Leads. The split is based on a custom 'record_type' field in BigChange or the presence of an open Quote. Teams specify the split rule during the discovery phase before migration runs.

BigChange

Company

maps to

Zoho CRM

Account

1:1
Fully supported

BigChange Companies map to Zoho CRM Accounts. Company name maps to Account Name; website maps to Website; industry maps to Industry pick-list. Parent-child company hierarchies in BigChange map to the Account.ParentId lookup in Zoho, preserving the organizational structure. Billing addresses, if stored on the Company record, migrate to the Account's billing address fields. Phone and email contacts on the Company map to secondary contact points in Zoho.

BigChange

Quote

maps to

Zoho CRM

Quotes (module)

1:1
Fully supported

BigChange Quotes with line items migrate to Zoho CRM Quotes. Each quote line item maps to a Zoho Quote Line Item tied to the Quote record. Quote status (Draft, Sent, Accepted, Rejected) maps to Zoho's Quote Status pick-list value-by-value. Custom pricing rules from BigChange rate cards require a separate rebuild plan using Zoho CRM Price Books.

BigChange

Job

maps to

Zoho CRM

Deal

1:1
Fully supported

BigChange Jobs are the central work-order entity — they carry status, priority, description, site address, assigned technician, and schedule. Jobs migrate to Zoho CRM Deals with the Job name as Deal Name, Job status mapped to Zoho Deal Stage values, and the site address stored as a custom field or in the Deal's description. Job priority maps to a custom Priority pick-list field on the Deal.

BigChange

Job Status

maps to

Zoho CRM

Deal Stage

1:1
Fully supported

BigChange job statuses (Scheduled, In Progress, On Hold, Completed, Cancelled) must be mapped value-by-value to Zoho CRM Deal stages. Teams choose which Zoho stage pick-list values correspond to each BigChange status. Completed jobs map to Closed Won; Cancelled maps to Closed Lost; in-flight statuses distribute across Open, Needs Analysis, and Proposal Sent.

BigChange

Job Site / Address

maps to

Zoho CRM

Account Address Fields

1:1
Fully supported

BigChange stores site addresses on Jobs, not on Accounts. The site address migrates as a custom multi-line text field on the related Zoho Account or Deal, or as a separate Address record in Zoho CRM's address model. Teams running jobs at multiple sites per customer should review whether to store the address on the Account or the Deal.

BigChange

Attachment / File

maps to

Zoho CRM

Attachments (module)

1:1
Fully supported

BigChange file attachments on Jobs, Quotes, and Contacts re-upload to Zoho CRM Attachments linked to the corresponding record. File size limits apply — Zoho CRM limits individual file uploads to 25 MB per attachment. Inline images in notes are downloaded and re-hosted in Zoho's file storage.

BigChange

Task / Activity (call, email, meeting)

maps to

Zoho CRM

Tasks / Events / Calls

1:1
Fully supported

BigChange activity logs (calls logged by technicians, customer emails, meeting notes) map to Zoho CRM Tasks, Events, and Calls. Original timestamps, owners, and parent-record links are preserved. Each activity type maps to the corresponding Zoho module: phone call logs to Calls, site visits to Events, administrative tasks to Tasks.

BigChange

Custom Field (Contact)

maps to

Zoho CRM

Custom Field on Contact

1:1
Fully supported

BigChange custom fields on Persons that have no direct Zoho CRM equivalent (e.g., trade licence numbers, insurance policy references, site-specific flags) are created as custom fields on the Zoho Contact module. Field type is preserved — text stays text, number stays number, pick-list stays pick-list. Teams must confirm layout assignments in Zoho after migration.

BigChange

Rate Card / Schedule of Rates

maps to

Zoho CRM

Price Books

1:1
Fully supported

BigChange Schedule of Rates and custom price lists have no native Zoho CRM equivalent. These do not migrate as data records. FlitStack delivers a Price Book setup plan: rate-card line items are exported as a CSV that Zoho admins import into Zoho CRM Price Books. Ongoing rate-card updates require a manual process in Zoho or a Deluge script.

BigChange

Scheduling / Technician Assignment

maps to

Zoho CRM

Custom Field / User Lookup

1:1
Fully supported

BigChange technician assignment and scheduling data cannot map to Zoho CRM's task model — Zoho has no native dispatch board or route-optimization capability. Technician assignments migrate as a User lookup field on the Deal (or as a custom pick-list linking to Zoho Users). Full scheduling rebuild requires Zoho Creator or a dedicated FSM tool post-migration.

Pair-specific challenges

  • BigChange data retention window limits historical export

    BigChange DaaS operates on a rolling 3-year data window — starting June 1, 2026, live data covers January 1, 2023 to present, with an annual rollover each January. Any records created before January 1, 2023 are not accessible via the DaaS API and will not appear in the migration export. Teams with multi-year job history must export those records from BigChange's reporting module before the migration window begins. Records that rotate out of the DaaS window cannot be recovered through the API and must be sourced from BigChange reports manually.

  • BigChange scheduling and dispatch logic has no Zoho CRM equivalent

    BigChange's core value proposition is its field-dispatch engine — technician assignment, scheduling, GPS tracking, mobile job cards, and real-time status updates. Zoho CRM has no native dispatch board, route optimization, or mobile job-card app. When jobs are migrated as Deals, the technician assignment maps to a static User lookup or custom pick-list field — it does not drive any scheduling or mobile workflow. Teams that rely on BigChange's scheduling layer must rebuild that capability in Zoho Creator, a dedicated FSM tool, or accept that job dispatch will be managed outside Zoho CRM after migration. This is a fundamental architectural gap, not a field-mapping problem.

  • Rate-card and Schedule-of-Rates data cannot be imported as CRM records

    BigChange stores rate cards and Schedules of Rates — per-trade, per-hour, or per-job-type pricing rules — as configuration data. Zoho CRM does not have a native rate-card or schedule-of-rates module. The rate-card line items can be exported from BigChange as CSV and imported into Zoho CRM Price Books, but the rules governing when each rate applies (trade type, customer-specific overrides, volume discounts) require a Deluge script or manual rebuild in Zoho CRM. FlitStack delivers the rate-card data as a structured CSV with a Price Book import plan, but the pricing logic rebuild is out of scope for the data migration.

  • Zoho CRM API credit throttling affects migration throughput on lower tiers

    Zoho CRM API uses a credit-based throttling model that varies sharply by edition. Standard edition allows 50,000 base credits plus 250 per user per day, with a ceiling of 100,000 credits per 24-hour window. Enterprise editions allow up to 50,000 base plus 1,000 per user per day, capped at 5,000,000 credits per 24-hour window. FlitStack's migration engine paces API calls within these limits and retries on 429 responses using exponential backoff, but large migrations on Standard-tier Zoho accounts may require multiple batch windows to complete. API credit consumption is monitored throughout the migration; clients receive a credit-usage report at completion.

  • BigChange custom fields exceeding Zoho's per-module limits must be pre-audited

    Zoho CRM enforces a maximum of 300 fields per module on Professional and above — but only 5 of those can be Lookup fields. Standard edition does not support Lookup or Formula field types at all. BigChange setups with more than 300 custom fields across its Contact and Job objects, or with deeply nested custom-object relationships, require a pre-migration audit to determine which fields map to Zoho standard fields, which require custom fields, and which should be dropped or merged. FlitStack includes a pre-migration schema audit that outputs a field-reduction plan before data movement begins.

Migration approach

Six steps for a successful BigChange to Zoho CRM data migration

  1. Pre-migration audit and BigChange data assessment

    FlitStack connects to your BigChange DaaS environment via read-only API access and audits the full data inventory: record counts per object (Person, Company, Quote, Job), custom field definitions, attachment volume, and activity history. We also check the BigChange DaaS data retention window to identify any records that have already rotated out of the live API. The output is a Migration Scope Document listing every object, field, and volume figure that will move, plus a list of any records that are outside BigChange's retention window and must be sourced from BigChange reports separately.

  2. Zoho CRM schema setup and custom field creation

    Before data moves into Zoho CRM, your admin (or FlitStack) creates the custom fields, layouts, and pick-list values needed for the migration. We deliver a Zoho schema setup plan based on the audit: custom fields on Contacts and Deals (e.g., Source_System_ID__c, Original_Create_Date__c, Job_Priority__c, Site_Address__c), pick-list value mappings for industry and job status, and any custom modules needed for BigChange custom objects. On Standard-tier Zoho accounts, Lookup and Formula field limitations are noted and addressed with text or multi-select alternatives.

  3. Owner and user resolution by email

    BigChange users and owners are matched to Zoho CRM users by email address. FlitStack generates a User Resolution Report listing every BigChange user, their email, and whether a matching Zoho user exists. Unmatched owners are flagged — your team either invites them to Zoho CRM first or assigns their records to a designated fallback Zoho user. No record lands in Zoho without a resolved owner.

  4. Sample migration with field-level diff

    A representative slice of records migrates first — typically 100–500 records spanning Contacts, Accounts, Quotes, Jobs, and a sample of activities. FlitStack generates a field-level diff between BigChange source values and Zoho CRM destination values for every mapped field. You verify that job status to Deal Stage mapping is correct, that custom fields populated as expected, that account lookups resolved, and that owner assignments are accurate. No full run commits until you sign off on the sample diff.

  5. Full migration with delta-pickup and audit log

    The full migration runs in sequenced order: Accounts first (parent objects before child lookups), then Contacts, then Quotes, then Jobs as Deals. Tasks, Events, and Calls migrate after their parent records. A delta-pickup window of 24–48 hours captures any records modified in BigChange during the cutover period. FlitStack generates an Audit Log covering every record created, updated, or skipped, with reasons for any skipped records. One-click rollback is available if reconciliation identifies unexpected discrepancies.

  6. Post-migration deliverables and workflow rebuild reference

    After migration, FlitStack delivers: a Data Migration Report with record counts and error summaries; a field-mapping spreadsheet documenting every translation; a BigChange Workflow Export PDF covering workflow definitions for your Zoho admin to reference during Blueprint rebuild; and a Rate Card CSV with a Price Book import guide. Zoho CRM automations (Blueprints, assignment rules, email alerts) must be rebuilt in Zoho — FlitStack provides the reference documentation to make that rebuild as guided as possible, but the automation rebuild itself is out of migration scope.

Platform deep dives

Context on both ends of the pair

Source

Strengths

  • Scheduling and mobile workforce management that demonstrably increases engineer job throughput from 1-2 to 6+ per day.
  • All-in-one platform combining job management, quoting, invoicing, vehicle tracking, and customer portals without tool sprawl.
  • Permanent access to BigChange University training across Core, Advanced, and Expert levels at no extra cost.
  • Customer-facing booking portal and business performance dashboards included on all tiers.
  • Hardware bundle with rugged tablet, vehicle tracking hardware, data SIM, and 2-year warranty reduces upfront deployment cost.

Weaknesses

  • Pricing opacity and perceived billing inflexibility — customers report difficulty reducing services or understanding cost increases.
  • System performance degrades noticeably in evenings, with some users reporting slowdowns and crashes on mobile map views.
  • High per-license cost (£99.95/month) makes the platform more suited to larger field service teams than small operators.
  • Feature richness and heavy customisation options create a steeper learning curve for smaller teams.
  • No publicly documented bulk API — DaaS is read-only and used for analytics, not direct data export for migration purposes.

Destination

Strengths

  • Generous free tier (3 users) with real CRM functionality — no artificial feature restrictions that prevent valid use cases.
  • Per-seat pricing is transparent and predictable; no contact-based billing surprises that inflate monthly invoices.
  • Blueprint visual workflow builder lets sales ops teams automate stage progressions without developer involvement.
  • Canvas drag-and-drop layout editor lets non-technical users customize module views and forms per role.
  • Active development cadence: API v8 is well-documented, supports bulk endpoints, and COQL queries handle complex filtering.

Weaknesses

  • Poor support quality and inconsistent SLA — Enterprise tier requires 50+ user minimum for Priority Phone support.
  • Daily export limits in the UI vary by plan tier, making large dataset extraction slow and planning-dependent.
  • Zia AI features are gated behind $40+/user Enterprise tier, not available to most SMB customers who chose Zoho for cost savings.
  • User-reported occasional UI inconsistencies and performance slowdowns on large datasets with many custom fields.
  • No EU-hosted option limits appeal for GDPR-sensitive companies; some competitors offer data residency guarantees Zoho does not.

Most BigChange-to-Zoho CRM migrations complete in 48–72 hours of clock time for under 50,000 total records. Larger setups with 500,000+ records, complex job histories, or more than 50 custom fields extend to 5–10 days. The longest single step is typically the Zoho schema setup phase — creating custom fields, pick-list values, and layouts — which runs in parallel with migration planning and does not add to the critical path if started early. BigChange DaaS API pagination and Zoho CRM API credit throttling are the primary throughput constraints on very large datasets.
