Why teams connect Nutshell and Smartrecruiters

Keep the people who own accounts in Nutshell in step with the workforce records in Smartrecruiters, so ownership, roles, and org structure stay current in both systems, in real time and in both directions.

Nutshell runs on people as much as on accounts: every contact, deal, and account has an owner, and those owners are employees whose roles, teams, and status are held in Smartrecruiters. Smartrecruiters is the system of record for the workforce, from new hires to promotions to departures, and often for the candidates the business is still deciding on. When the two systems are connected only by re-keying or an overnight export, they drift apart, and the CRM ends up assigning accounts to people who have left, holding territories that no longer match the org chart, and waiting days to give a new rep access.

Stacksync syncs Activities, Tasks, Notes, Products in Nutshell with Jobs, Job Postings, Interviews, Offers in Smartrecruiters field by field, in real time, and in both directions. You decide which system owns which fields, so Smartrecruiters stays authoritative on roles and org structure while Nutshell keeps ownership and territory current, and Stacksync resolves conflicts by the rules you set.

Common use cases

  • 01 Sync Nutshell leads into a warehouse or Postgres so small B2B teams can report on pipeline without exports.
  • 02 Push closed-won leads to accounting software to trigger invoicing automatically.
  • 03 Two-way sync Candidates and Applications with Postgres so recruiting-ops apps read and update hiring status, tags, and custom fields in SQL while recruiters keep working in SmartRecruiters.
  • 04 Write enriched or sourced Candidates from external sourcing tools into SmartRecruiters and keep contact fields refreshed as data changes.

Common sync patterns

One directory of people

A person's name, title, email, phone, or manager corrected in either system updates the other, so both stop maintaining separate copies of the same individual.

Where Smartrecruiters tracks people the business also engages: contacts stay in sync

A person recorded in Smartrecruiters, such as a candidate or applicant, can create or update the matching contact in Nutshell, so relationship history and outreach are not rebuilt from scratch when the same individual appears in both.

New team members provisioned when they are hired

When Smartrecruiters records a new hire, a matching user or owner is created in Nutshell, so a new rep can start working accounts without waiting on a manual setup ticket.
