Hire a senior accountant when a working process needs stronger execution. Hire a controller when the process needs an accountable owner. Start with the work left on your desk after the last close, then choose the title.
What is actually missing?
The schedules are late
Reconciliations, accruals or intercompany schedules have clear instructions and a reviewer, but the team cannot finish them reliably. A senior accountant is a sensible starting point.
The close has no owner
Files arrive, but you still set priorities, resolve dependencies and decide whether the reporting pack is ready. Explore controller ownership, with authority that matches the responsibility.
The inputs are missing
Neither hire can reconcile a bank account without the statement or close revenue without reliable source data. Fix access, input deadlines and business ownership alongside the staffing decision.
Senior accountant: dependable accounting work
Give this person a defined set of accounts, entities or reporting responsibilities. The work may include complex reconciliations, accruals, draft financial statements and review of colleagues' schedules.
A useful deliverable: a reconciled balance sheet with supporting evidence, explained differences and open issues ready for the designated reviewer.
Agree before hiring: who sets priorities, resolves policy questions and approves the final output. Substantial accounting responsibility does not automatically include authority over the whole finance function.
Controller: dependable accounting operations
Give this person responsibility for how the work comes together: the close calendar, review standards, dependencies, reporting readiness and escalation. A controller may also prepare schedules and resolve accounting issues directly.
A useful deliverable: a reporting pack supported by reviewed schedules, with clear status for unresolved matters and decisions requiring approval.
Agree before hiring: which decisions the controller can make, how they obtain information from the business and what remains with the CFO or directors.
Titles vary. A small-company role may combine both briefs; a senior accountant in a larger group may have deeper expertise in a particular technical area. Assess the assignment and the candidate's experience.
Three situations, three different briefs
Illustrative situations, not Nexteam client case studies.
1. A functioning process, an unfinished backlog
The controller has a timetable and review process, but two entities' reconciliations keep arriving late because the preparer lacks capacity.
Start with a senior accountant. Assign the entities, systems and deadlines, and confirm that the controller can review the additional output. A temporary backlog may justify temporary support.
2. Ready files, an overloaded CFO
Accountants submit schedules using different definitions of “done.” Nobody coordinates dependencies or brings unresolved issues together, so the CFO rebuilds the reporting pack every month.
Start with controller ownership. Name the person who will coordinate the close and set the review standard before adding more preparation capacity.
3. One unfamiliar transaction
The team usually closes reliably, but a new transaction raises an accounting question outside its experience.
Start with relevant specialist support. Define the question, evidence and qualified reviewer. Neither job title guarantees the technical expertise required.
Test the responsibility you will delegate
For a senior accountant: provide a fictional reconciliation with an unexplained balance and incomplete support. Ask for investigation steps, evidence needed and a short escalation note. Look for traceable reasoning rather than a forced answer.
For a controller: provide a fictional close calendar with missing inputs and conflicting deadlines. Ask for priorities, owners, review checkpoints and decisions to escalate. Look for a workable process and clear authority boundaries.
For either role, ask what the candidate personally owned in a previous assignment, who reviewed it and how they handled an error. Verify the relevant accounting framework, systems and business complexity.

Choose capacity separately from seniority
A small team may need controller judgment on a recurring part-time schedule. A busy team may need a full-time senior accountant under its existing controller. Map both the hours and the days when review or decisions are needed.
Compare the complete arrangement: professional charges, internal review time, transition work and any specialist support. The broad ranges in the finance talent cost guide are planning context, not a quote for either role.
If you already use a delivery center, the hybrid finance team guide explains how senior review can complement an established preparation team. For part-time oversight versus temporary role coverage, read fractional vs interim controller.
