Overview
Moving from Shark Byte CRM to Nutshell is a migration from a vertical-specific estimating platform into a general-purpose mid-market CRM. Shark Byte's core objects (Estimates, Proposals, Service Agreements) do not have direct Nutshell equivalents, so we map them to a combination of Opportunities, custom fields, and pipeline configuration. The primary migration risk is Shark Byte's lack of a documented public API, which means we coordinate with their team for CSV exports and file downloads, extending the discovery phase. We preserve contract-term pricing logic from Shark Byte's estimating templates as custom fields on the migrated Opportunity records, and we extract mobile survey attachments (photos, site condition data) separately as file imports into Nutshell's document management layer. Workflows, sequences, and automations do not migrate; we deliver a written inventory for the customer's admin to rebuild in Nutshell. Nutshell's Import2 tool and free migration support are available during the transition, and we run the field-alignment preview in a trial sandbox before any production data moves.

Object mapping
Each row shows how a Shark Byte CRM 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.
Shark Byte CRM
Customer
Nutshell
Company + Person
1:manyShark Byte Customer records represent the end-client organization or homeowner and contain both company-level fields (name, address, service history) and individual contact details (name, phone, email, role). We split these into Nutshell Company records (for organizational-level customers) and Person records (for individual contacts at each customer site). The primary Customer identifier and service history attach to the Company as custom fields. Role information from the source becomes a custom Person field in Nutshell.
Shark Byte CRM
Contact
Nutshell
Person
1:1Shark Byte Contact records map directly to Nutshell Person records. Name, phone, email, and role fields migrate 1:1. Any custom fields on the Contact record migrate to Nutshell custom Person fields. The Person record is linked to the parent Company record via Nutshell's company-person relationship at migration time using a dedupe key of email address.
Shark Byte CRM
Estimate
Nutshell
Opportunity + Custom Fields
1:manyShark Byte Estimates are the core product object and include line items, labor rates, material costs, and the contract-term classification (1-3 year, 3-5 year, 10+ year). We map Estimates to Nutshell Opportunities with the total estimated value as the Opportunity amount. Contract-term classification migrates as a custom picklist field on the Opportunity. Individual line items are stored as a JSON blob in a custom text area field for reference, since Nutshell's native Opportunity does not include a line-item sub-object. If Nutshell Quotes is active on the destination account, we can map Estimate line items to Quote Line Items instead.
Shark Byte CRM
Proposal
Nutshell
Opportunity (with document attachment)
1:1Shark Byte Proposals are generated from Estimates and include pricing, scope, and terms. We map Proposal records to the related Nutshell Opportunity and preserve the proposal document as a file attachment on the Opportunity record. The proposal status (draft, sent, accepted, rejected) migrates as a custom Opportunity field. If the original Proposal PDF is available from Shark Byte exports, we import it as a Nutshell attachment on the linked Opportunity.
Shark Byte CRM
Service Agreement
Nutshell
Opportunity (recurring type) + Custom Fields
1:1Shark Byte Service Agreements are recurring maintenance contracts tied to specific contract-term buckets (1-3, 3-5, 10+ years). We map these to Nutshell Opportunities with a custom Service Agreement flag set to true, contract start and end dates as custom date fields, and term length as a custom picklist field matching the source classification. Annual or recurring value migrates to the Opportunity amount field with a custom recurring flag indicating the payment model.
Shark Byte CRM
Work Order
Nutshell
Task + Custom Fields
1:1Shark Byte Work Orders track individual jobs dispatched to technicians with status, assigned technician, and line items. We map Work Orders to Nutshell Task records with status mapped to Nutshell's Task status values. The assigned technician resolves to the Nutshell User record by email match. Work Order line items and equipment specifications migrate as custom Task fields. Any linked photos from mobile surveys migrate as file attachments on the Task.
Shark Byte CRM
Attachment
Nutshell
File (Company, Person, or Task)
1:1Shark Byte CRM attachments (scope documents, mobile survey photos, signed agreements) on Customer, Estimate, Proposal, and Work Order records migrate to Nutshell file attachments on the corresponding destination record. We extract all available attachments at original resolution where possible. Some images from older mobile surveys may be compressed in the source; we note any resolution gaps during extraction. The parent record type is preserved during migration so attachments land on the correct Nutshell entity (Company, Person, or Task).
Shark Byte CRM
Custom Properties (Estimates)
Nutshell
Custom Opportunity Fields
lossyShark Byte custom fields on Estimates (equipment specifications, contract classification codes, regional pricing modifiers) require pre-creation in Nutshell before migration. We define the custom Opportunity fields with matching types during the schema design phase, including picklists, date fields, and text fields. The custom field names in Nutshell mirror the Shark Byte field labels for admin recognition after cutover.
Shark Byte CRM
Custom Properties (Service Agreements)
Nutshell
Custom Opportunity Fields
lossyShark Byte custom fields on Service Agreements (coverage tier, auto-renewal flags, escalation clauses) migrate to Nutshell custom Opportunity fields. We create these as a separate field group during schema design so they are visually grouped on the Opportunity layout alongside the standard contract-term fields.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Shark Byte CRM gotchas
No publicly documented API for programmatic data export
Estimating templates and contract-term mappings are custom to the account
Mobile survey attachments may have inconsistent file formats
Small vendor footprint complicates support coordination during cutover
Nutshell gotchas
Contact tier limits enforced on import
No bulk API endpoint requires paginated extraction
Email sequences not exportable via API
Foundation plan disables key sales features
Pair-specific challenges
Migration approach
Discovery and export coordination
We audit the source Shark Byte account for record counts across all objects (Customers, Estimates, Proposals, Service Agreements, Work Orders, Contacts, Attachments), custom field definitions, active contract-term bucket configurations, and any custom estimating templates. Because Shark Byte has no public API, we simultaneously coordinate with their team to confirm what export formats are available (CSV, file downloads) and whether any bulk extract tooling exists. This phase typically runs two to three weeks due to vendor coordination timelines.
Schema design and custom field creation in Nutshell trial
We design the destination schema in a Nutshell trial or sandbox environment. This includes creating all custom fields required for Shark Byte's estimating data (contract-term picklists, line-item reference fields, equipment specification fields), Service Agreement custom fields, and Work Order fields mapped to Task. We configure pipeline stages in Nutshell to reflect any Shark Byte pipeline conventions the customer uses. The trial sandbox serves as the validation environment before production migration begins.
Field mapping and Import2 preview
We use Nutshell's Import2 integration to preview field mappings between the exported Shark Byte CSV data and Nutshell's destination fields. Import2's automatic field mapping is reviewed and adjusted for every custom field, and we validate that contract-term classifications, status values, and date formats translate correctly. This step runs in the Nutshell trial sandbox and produces a mapping validation report before any production data moves.
Record migration in dependency order
We run production migration in record-dependency order: Companies (from Shark Byte Customers), Persons (from Shark Byte Contacts with Company linkage), Opportunities (from Estimates and Proposals), Service Agreement Opportunities (with contract-term custom fields), Tasks (from Work Orders), and file attachments last. Owner resolution uses email matching against the Nutshell User table. Each phase emits a row-count reconciliation report before the next phase begins.
Attachment extraction and import
After core records are migrated, we extract all file attachments from Shark Byte (photos from mobile surveys, scope documents, signed proposals) as a separate migration phase. Attachments are organized by parent record type and imported to the corresponding Nutshell entity (Company, Person, or Task) using Nutshell's file import capability. We note any format inconsistencies or resolution gaps from the source extraction and flag them in the delivery report.
Cutover, validation, and automation inventory handoff
We freeze Shark Byte writes during cutover, run a final delta migration of any records modified during the migration window, then enable Nutshell as the system of record. We deliver the automation inventory document listing every active Shark Byte workflow and recommended Nutshell workflow equivalent to the customer's admin team. We support a one-week hypercare window for reconciliation issues raised during the first days of Nutshell usage. We do not rebuild Shark Byte workflows as Nutshell workflows inside the migration scope.
