Overview
Summit Service Systems organizes around field-service operations: service requests, dispatch, assets, and technician schedules. Nutshell is a sales CRM that tracks People, Companies, Leads, Deals, and Activities. The migration maps your service-account records to Nutshell Companies and People, work-order and service-history data to Activities and Deals, and custom fields to Nutshell's extensible custom field model. Summit's asset-management and dispatch-scheduling constructs have no direct CRM equivalent — we surface these as custom fields and notes for reference rebuild in Nutshell's workflow tools. FlitStack uses Summit's API export endpoints to pull full record sets, sequences the load into Nutshell so foreign-key relationships resolve correctly, and runs a delta-pickup window (24-48 hours) to capture any records modified during cutover. Sample migration with field-level diff confirms mapping accuracy before the full run commits. The migration also handles technician and user resolution by matching email addresses between systems, and preserves original create dates as custom fields since Nutshell's native timestamps reflect migration time rather than source-system creation dates.
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 Summit Service Systems 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.
Summit Service Systems
Customer / Account
Nutshell
Company
1:1Summit customer records (business name, billing address, contact details) map directly to Nutshell Companies. Primary contact within the customer record maps to a linked Person. Multi-location customers in Summit with separate site records create separate Company entries linked via Nutshell's parent-company field.
Summit Service Systems
Contact / Service Contact
Nutshell
Person
1:1Individual contact records in Summit (name, email, phone, role) migrate to Nutshell People. Primary contact flag in Summit maps to Nutshell's primary-contact designation. Service contacts who are also sales leads create both a Person and a Lead record in Nutshell based on the contact's status in Summit.
Summit Service Systems
Service Request / Work Order
Nutshell
Activity + Deal
1:1Open and recent closed work orders migrate as Nutshell Activities (Tasks) with the work-order number, description, and status preserved in custom fields. High-value or recurring service contracts map to Nutshell Deals so the revenue history is visible in the pipeline. Completed one-off service calls migrate as historical Tasks.
Summit Service Systems
Lead / Prospect
Nutshell
Lead
1:1Prospective customers in Summit's pipeline map 1:1 to Nutshell Leads. Lead status in Summit (New, Contacted, Qualified) maps to Nutshell's Lead Status pick-list via value mapping. Unqualified leads with no contact history become Nutshell Leads; those with prior service interactions also create linked Person records.
Summit Service Systems
Asset / Equipment Record
Nutshell
Company (custom field) + Note
1:1Summit asset records have no direct Nutshell equivalent. Asset ID, equipment type, serial number, and service contract status migrate to custom fields on the linked Company record. Detailed asset specifications migrate as Nutshell Notes attached to the Company, providing reference context without requiring a separate object.
Summit Service Systems
Location / Site
Nutshell
Company (additional record)
1:manySummit locations and sites attached to a customer split into separate Nutshell Company records when they represent distinct service addresses. Each location-Company links back to the parent customer via the parent-company field. Single-site customers produce one Company; multi-site customers produce a parent Company with child Company records per location.
Summit Service Systems
Technician / Field Worker
Nutshell
User
1:1Summit technician and field-worker records resolve to Nutshell Users by email match. Technicians without Nutshell login credentials become inactive users or are reassigned to the owner of their service accounts. Dispatch assignment history migrates as Activities on the related service records.
Summit Service Systems
Invoice / Billing Record
Nutshell
Deal + Activity
1:1Summit invoices map to Nutshell Deals with the invoice amount as the Deal value and invoice status mapped to a custom Deal-status field. Line-item detail migrates as Activities attached to the Deal for audit continuity. Recurring service contracts create linked Deals with custom fields for contract terms and renewal dates.
Summit Service Systems
Custom Object (Service Contract)
Nutshell
Deal + Custom Fields
1:1Service contracts in Summit (SLA tier, coverage period, response-time commitment) migrate as Nutshell custom fields on the linked Deal or Company. SLA tier maps to a custom pick-list; coverage dates map to custom date fields. Nutshell has no native contract object, so the contract relationship is preserved through custom fields and linked records.
Summit Service Systems
Custom Field (any entity)
Nutshell
Custom Field (same entity)
1:1Any Summit custom fields on Customer, Contact, Service Request, Asset, or Location migrate as Nutshell custom fields on the corresponding entity. Field type mapping applies: Summit text fields to Nutshell text fields, pick-lists to Nutshell choice fields, date fields to Nutshell date fields. Multi-select pick-lists in Summit require custom field configuration in Nutshell to accept multiple values.

Migration approach
Export Summit data via scoped API access
FlitStack connects to Summit Service Systems using scoped API credentials with read-only access to your customer, contact, service-request, asset, location, and custom-object records. We pull the full dataset in a structured export, preserving all custom fields, timestamps, and owner assignments. Owner resolution begins here — technician and user emails are matched against the email list we will use for Nutshell user assignment.
Audit data quality and define exclusion criteria
Before mapping, we profile the Summit export for duplicates, stale records (closed accounts with no activity in 18+ months), and incomplete records missing required fields for Nutshell validation. We work with your team to define exclusion criteria so only active, valuable records enter Nutshell. This reduces record count, lowers migration cost, and keeps your Nutshell CRM clean from day one. The audit also identifies records with special handling requirements such as multi-site customers, records with missing email addresses, or accounts with extensive custom field populations.
Sequence and load into Nutshell with foreign-key resolution
Migration runs in dependency order: Companies first (since People link to them), then People and Leads, then Deals and Activities, then custom fields. This sequence ensures Nutshell's foreign-key relationships resolve correctly. Asset and location records map to Company custom fields or split into child Companies as pre-agreed. Each batch is validated against Nutshell's field requirements before the next batch begins.
Run sample migration with field-level diff
A representative sample (typically 100-500 records spanning each entity type) migrates first. We generate a field-level diff comparing source values against destination values so you can verify that pick-list mappings, custom field assignments, date formats, and owner resolution are all correct. You approve the sample before the full run commits. Any mapping adjustments are documented and applied before the bulk load begins. This step catches value-mapping gaps early and prevents them from propagating through the full dataset.
Cut over with delta-pickup and rollback capability
The full migration runs against your live Nutshell instance. A delta-pickup window (24-48 hours after the main load) captures any records created or modified in Summit during the cutover period. Your team continues working in Summit during this window — FlitStack uses scoped read access only, so there is no operational disruption. An audit log tracks every migrated record, and one-click rollback is available if reconciliation identifies unexpected gaps.
