Maintain account access, user permissions, integrations and documentation across the business toolset.

As tools accumulate, so do orphaned accounts, excessive permissions and undocumented integrations. We inventory the stack, assign business ownership, apply role-based access, document integration dependencies and establish an offboarding routine. Credentials remain under the owner's control; administrative work is performed with least privilege.
The problem it addresses
Nobody can list every tool the business pays for or who can access customer data.
Who it is for
Businesses with many subscriptions, former team members still holding access, or integrations nobody can explain.
What the engagement produces
- A system, account and owner inventory
- A role and permission matrix
- An onboarding and offboarding access checklist
How the work runs
- 01
Scope
Confirm the situation, the decision to be made, responsibilities, fees and what is explicitly out of scope. Third-party costs are identified before work begins.
- 02
Work
Interview the people closest to the work, review the records that exist, build the change and test it against real exceptions rather than a demo.
- 03
Handoff
Document what was built, train the owner, record open items and define whether ongoing support is needed. The business should not depend on Nexus to operate the result.
What it does not do
Stated before the engagement so the scope is honest. Additional requirements are scoped and confirmed in writing.
- Nexus does not retain owner credentials or guarantee the security of third-party platforms.
- Security incidents require the provider's process and, where appropriate, specialist response.
- Software licences, telephony charges and messaging fees are billed by their providers and are separate from Nexus fees.
- Ongoing support is provided under a defined scope and response window, not unlimited availability.
