Overview
Estimate Rocket is a field-service estimating and project-management tool built for contractors — its data model centers on Projects containing Clients, Estimates, Work Orders, Line Items, Employees, and a Schedule. Nutshell CRM models sales around People (contacts), Companies, Leads, Deals (opportunities), and Activities. The migration maps Estimate Rocket's combined client-contact records into Nutshell's separate People and Companies objects, routes Estimates and Work Orders to Nutshell Deals with custom fields storing line-item summaries, and converts Employee assignments into Deal owner and Activity owner resolution by email match. Nutshell has no native estimating, work-order, or field-user management — those Estimate Rocket constructs become custom fields or are surfaced as manual-rebuild references. FlitStack AI reads Estimate Rocket data via the Zapier-connected API and loads Nutshell via its JSON-RPC API, sequencing foreign-key resolution (Companies → People → Deals) correctly before committing the full run. A delta-pickup window captures any records modified during cutover. The process also logs each transformation for auditability.
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 Estimate Rocket 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.
Estimate Rocket
Client (Contact)
Nutshell
Person
1:1Estimate Rocket client records (name, email, phone, address) map directly to Nutshell Person records. The client record also carries the company name which FlitStack extracts to create a linked Nutshell Company record first, then links the Person to it via the account lookup.
Estimate Rocket
Client (Company Name)
Nutshell
Company
1:1Estimate Rocket does not have a separate Company object — company information lives inside the Client record as a text name field. FlitStack extracts the company name, deduplicates across all client records sharing the same name, and creates a single Nutshell Company per unique name, then links all associated Person records to it.
Estimate Rocket
Project
Nutshell
Deal
1:1Each Estimate Rocket Project becomes a Nutshell Deal. The Project name maps to Deal name; Project status (Active, Won, Lost, Archived) maps to Nutshell's Deal status. Original project create date is preserved as a custom field since Nutshell Deals track created date differently.
Estimate Rocket
Estimate
Nutshell
Deal (linked)
many:1Estimate Rocket Estimates are child records of Projects. FlitStack merges the Estimate total amount into the parent Project's Nutshell Deal Amount field. If a Project has multiple Estimates (initial, revision), the most recent approved estimate amount is used as the primary Deal amount, and earlier estimate totals are preserved as custom fields.
Estimate Rocket
Line Item
Nutshell
Custom fields on Deal
1:1Estimate Rocket line items (name, quantity, unit price, unit cost, section, type) have no direct Nutshell equivalent. FlitStack creates custom fields on the Nutshell Deal — Line_Item_Summary__c stores a text summary of the top line items; individual material and labor totals go into Material_Total__c and Labor_Total__c custom number fields.
Estimate Rocket
Work Order
Nutshell
Deal (stage / Activity)
1:1Work Orders in Estimate Rocket represent scheduled execution of an approved estimate. FlitStack maps the Work Order status to a Nutshell Deal stage change (e.g., 'Work Ordered' → Nutshell stage 'Negotiation') and creates a linked Activity note capturing the Work Order description and assigned technician.
Estimate Rocket
Employee
Nutshell
Person (internal user) / Activity owner
1:1Estimate Rocket Employees with estimator or admin roles map to Nutshell internal users by email match. FlitStack resolves each Estimate Rocket owner_id to the corresponding Nutshell user. Field users (clock-only access) have no Nutshell equivalent — their names are preserved in activity logs but they do not become Nutshell users.
Estimate Rocket
Schedule / Appointment
Nutshell
Activity
1:1Estimate Rocket Schedule entries (appointment time, assigned employee, related project) map to Nutshell Activities. FlitStack preserves the original start/end datetime and links each Activity to the parent Project's Nutshell Deal. All-day events and task-type schedule entries map to Nutshell Tasks with the All-Day flag set.
Estimate Rocket
Follow-Up Campaign
Nutshell
Nutshell Sequences
1:1Estimate Rocket Follow-Up Campaigns are email automation series triggered on project lifecycle events. Nutshell Sequences provide equivalent automation on Deal stage and lead status changes but are rebuilt manually. FlitStack exports the campaign definition (trigger event, step sequence, delay days, email body) as a JSON reference document for Nutshell admin to rebuild.
Estimate Rocket
Invoice
Nutshell
Activity note / Custom field on Deal
1:1Estimate Rocket Invoices carry a status (Sent, Paid, Overdue, Void) and payment info. FlitStack maps invoice status to a custom field Invoice_Status__c on the Nutshell Deal and appends a deal Activity note with the invoice total, date, and payment terms. Nutshell does not have a native invoicing object.
Estimate Rocket
Time Entry
Nutshell
Activity
1:1Estimate Rocket time entries (employee, project, hours, work type) become Nutshell Activity records with a custom Work_Hours__c number field and a Work_Type__c pick-list field. Original timestamps and associated project are linked. Nutshell's time tracking is not native — these custom fields enable manual time reporting.
Estimate Rocket
Map View / Address
Nutshell
Company address / Person address
1:1Estimate Rocket project addresses map to the address fields on the linked Nutshell Company or Person record. Nutshell has no Map View — FlitStack preserves the full address so it can be displayed in external map tools post-migration. Projects with unresolvable addresses are flagged for manual review.

Migration approach
Audit Estimate Rocket data via Zapier-connected API before migration
FlitStack connects to your Estimate Rocket account through the Zapier integration at estimaterocketapi.com. We validate API scope permissions (:read/:write), re-authenticate if needed per the June 2024 scope change, and run a pre-migration data audit that counts Projects, Clients, Estimates, Work Orders, Line Items, Employees, and Schedule entries. The audit output identifies duplicate company names across client records, projects with no client link, and any custom Estimate Rocket fields not in the standard schema — all of which feed the mapping plan.
Build Nutshell-side schema: custom fields, stage mapping, and user resolution
Before data lands, FlitStack delivers a Nutshell-side setup plan: the custom fields required on Deal (Line_Item_Summary__c, Material_Total__c, Labor_Total__c, Invoice_Status__c, Invoice_Total__c, Original_Create_Date__c, Source_System_ID__c), the mapping of Estimate Rocket project status values to Nutshell Deal stage IDs, and the Deal pipeline configuration. Your Nutshell admin creates these fields and stages. Simultaneously, we match Estimate Rocket employee emails to existing Nutshell users — unmatched employees are flagged so your team can invite them or assign their records to a fallback owner.
Sequence migration: Companies → People → Deals → Activities
Nutshell requires Companies before People (via account link) and People before Deals (for contact associations). FlitStack sequences the migration in dependency order: first, all unique company names extracted from Estimate Rocket clients are inserted as Nutshell Companies; second, each Estimate Rocket Client record is inserted as a Person linked to the corresponding Company; third, Estimate Rocket Projects become Nutshell Deals with Estimate totals and line-item summaries in custom fields; fourth, Work Orders, Schedule entries, and Time Entries are inserted as Nutshell Activities linked to their parent Deals. Each step validates foreign-key integrity before proceeding to the next.
Run sample migration with field-level diff before full commit
FlitStack migrates a representative slice — typically 50–100 records spanning a mix of clients, projects, estimates, work orders, and schedule entries — and generates a field-level diff report. The report shows each mapped field's source value, destination value, and transformation applied. You verify that Estimate totals landed in the correct Deal amount field, that line-item summaries are readable, that Schedule entries link to the right Deal, and that owner resolution by email produced the expected Nutshell user assignments. Approval of the sample diff triggers the full migration.
Full migration with delta-pickup window and audit log
The full migration runs against your Nutshell account using Nutshell's JSON-RPC API. A delta-pickup window — typically 24–48 hours — captures any Estimate Rocket records created or modified during the migration run (new client entries, updated project statuses, newly scheduled appointments). FlitStack maintains a complete audit log of every record inserted, updated, or skipped. If reconciliation identifies mismatches, one-click rollback reverts the Nutshell environment to its pre-migration state so your team can correct the mapping and re-run without data loss.
