Overview
Moving from Accelo to Nutshell is a structural narrowing from a full PSA suite to a focused CRM. Accelo bundles CRM, project delivery, time tracking, and billing under one roof; Nutshell is purpose-built for sales pipeline management with a clean interface and no seat minimums. We map Accelo's Companies to Nutshell Accounts, Contacts to People, Deals to Opportunities, and Jobs to Project note records (since Nutshell has no native project object). Accelo's Tickets migrate to Nutshell Cases, and time entries surface as Activity history. Custom fields on Accelo Companies and Contacts transfer to Nutshell custom fields; custom fields on Jobs, Tasks, and Tickets require CSV export or manual post-migration entry since Accelo's API does not expose those endpoints. Workflows, Retainers, and Invoices do not migrate; we deliver a written inventory of automations for the customer's admin to rebuild in Nutshell.
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 Accelo 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.
Accelo
Company
Nutshell
Account
1:1Accelo Companies map directly to Nutshell Accounts. The Accelo company name becomes the Account name, address fields map to Account billing address, and industry categories map to Account categories if configured. Custom fields on Accelo Companies transfer to Nutshell Account custom fields via the API. The company ID is preserved for audit purposes.
Accelo
Contact
Nutshell
People
1:1Accelo Contacts map to Nutshell People. The contact's first name, last name, email, phone, and title transfer directly. The contact-to-company affiliation (Affiliation in Accelo) becomes the People record's Account link. Custom fields on Accelo Contacts map to Nutshell People custom fields. Email serves as the dedupe key during import.
Accelo
Deal (Sales)
Nutshell
Opportunity
1:1Accelo Deals map to Nutshell Opportunities. The deal name becomes the Opportunity name, value maps to Amount, close date maps to Close Date, and stage names map to Nutshell pipeline stage values. Accelo deal owners resolve to Nutshell User records by email lookup. Custom fields on Deals transfer to Opportunity custom fields.
Accelo
Job (Project)
Nutshell
Project Note (linked to Account)
lossyAccelo Jobs have no direct Nutshell equivalent since Nutshell does not include a native project object. We create a structured text note attached to the associated Account that captures the Job title, description, status, phases, milestones, assignees, and dates. This preserves the Job as readable historical record without requiring a separate project management tool in Nutshell.
Accelo
Task
Nutshell
Activity (Task)
1:manyAccelo Tasks map to Nutshell Activity records. Tasks associated with a Job carry a reference to the Project note created from that Job. Task status (pending, in progress, completed), due date, and assignee transfer. Task checklists migrate as bulleted text within the Activity description. Tasks without a parent Job become standalone Activities linked to the associated Contact or Account.
Accelo
Ticket
Nutshell
Case
1:1Accelo Tickets map to Nutshell Cases. The ticket subject becomes the Case subject, description maps to the Case body, and status maps to Case status values. Priority and assignee transfer to Case priority and owner. Custom fields on Accelo Tickets that are accessible via CSV export transfer to Case custom fields; API-inaccessible custom fields are flagged for manual post-migration entry.
Accelo
Time Entry
Nutshell
Activity (Activity Log)
lossyAccelo Time Entries map to Nutshell Activity records as activity log entries. The entry description, duration, billable flag, and date transfer. Since Nutshell has no native time tracking object, these entries appear as logged Activities on the associated Contact or Account. Billable flag status is preserved in a custom field for reporting. Hourly rate metadata migrates to a custom field if the destination Nutshell plan supports custom fields.
Accelo
Staff
Nutshell
User
1:1Accelo Staff records map to Nutshell Users. Staff email addresses serve as the match key. Accelo Staff with no corresponding Nutshell User go to a reconciliation queue for the customer's admin to provision before record migration proceeds.
Accelo
Attachment
Nutshell
File
1:1Attachments on Accelo Jobs, Tasks, and Tickets download individually via the API and re-upload to the linked Nutshell record (Account, People, or Case). Filename and linked object association are preserved. Large file attachments may require chunked download and upload due to API rate limits.
Accelo
Lead
Nutshell
People (unqualified) or Opportunity contact
1:manyAccelo Leads with no associated Company map to Nutshell People records without an Account link. Leads with a Company association map to People linked to the corresponding Account. Lead source and status transfer to People custom fields or Activity records.

Migration approach
Discovery and data audit
We audit the source Accelo account across all modules in use: Companies, Contacts, Deals, Jobs, Tasks, Time Entries, Tickets, Staff, Attachments, and any custom fields configured per object. We identify which modules are actively used versus historical, flag any custom fields on Jobs, Tasks, and Tickets (which require CSV export), and assess total record counts per object. This output is a written migration scope with record counts, object list, and a decision on whether to migrate Time Entries as Activities and whether Jobs should become Project notes or be omitted.
Nutshell destination setup
We configure the Nutshell destination account before migration begins. This includes creating any required custom fields on People, Accounts, and Opportunities to receive Accelo custom field data, configuring pipeline stages to match Accelo deal stages, setting up Case statuses to match Accelo ticket statuses, and provisioning Nutshell User accounts for any Accelo Staff members who will be active in Nutshell. The Nutshell admin grants API access credentials that we store securely for the migration.
Accelo CSV export for non-API custom fields
For custom fields on Accelo Jobs, Tasks, and Tickets that are not accessible via API, we guide the customer through exporting XLS files from Accelo's UI for each object type. We parse the CSV exports, match records by ID to the API-extracted records, and merge custom field values into the migration dataset. This step runs in parallel with API extraction to avoid extending the critical path.
Record migration in dependency order
We run migration in the following order: Accounts (from Accelo Companies), People (from Accelo Contacts with Account link resolved), Opportunities (from Accelo Deals with Account link and User assignment resolved), Cases (from Accelo Tickets), Project notes (from Accelo Jobs attached to the correct Account), Activities (from Accelo Tasks and Time Entries), and Attachments (downloaded from Accelo and re-uploaded to the linked Nutshell record). Each phase emits a row-count reconciliation report before the next phase begins.
Reconciliation and validation
We run a reconciliation comparing record counts and field completeness between the Accelo source and the Nutshell destination. We spot-check 20-30 records per object type for field-level accuracy against the source. Any records with failed lookups (Contacts without resolved Account links, Cases without resolved User assignments) go to a resolution queue. The customer reviews and approves the reconciliation report before cutover.
Cutover, delta sync, and handoff
We freeze Accelo writes during the cutover window, run a final delta migration of any records created or modified during the migration window, then mark Nutshell as the system of record. We deliver a written inventory of Accelo Workflows, Retainers, and Invoices that do not migrate, along with the financial summary document for billing records. We provide a one-week hypercare window for reconciliation issues raised by the customer's team. We do not rebuild Accelo Workflows as Nutshell automation rules; that work is covered in the automation inventory handoff document.
