Outsourced Controller Services: What’s Included, How Often, and What You Receive
Outsourced controller services cover the monthly close, the adjusting journal entries, balance sheet reconciliations, a monthly reporting package, cash flow forecasting and the internal controls around them, delivered by a firm rather than an employee. The table below shows what is done, how often, and what you receive.
The label varies between providers. Some use “controller” for bookkeeping, others for a part-time CFO. The useful way to buy this service is to compare scope line by line: who does the work, on what cadence, and what lands in your inbox at month end. If you are still deciding whether to outsource at all, start with outsourced vs in-house controller, which covers the hire-or-outsource decision.
What is included in outsourced controller services?
The table is a scope checklist, not a promise that every engagement includes every line. Agree the recurring close and reporting work separately from optional reporting, cleanup and systems projects; confirm the cadence in the proposal.
| Work | Cadence | What you receive |
|---|---|---|
| Month-end close to a set date | Monthly | Closed books for the month, with a fixed close calendar |
| Adjusting journal entries (accruals, prepaids, deferred revenue, amortization) | Monthly | Entries made in your system, not left for year end |
| Bank, card and balance sheet reconciliations | Monthly | Reconciled balances with support for each account |
| Monthly reporting package | Monthly | Cash flow, balance sheet and profit and loss, with commentary on what moved |
| Variance analysis and budget-to-actuals | Monthly or quarterly | Explanations of variances and where costs can be reduced |
| Cash flow forecast | Monthly, or weekly when cash is tight | A rolling forecast with burn and runway where relevant |
| Budgeting and forecasting | Quarterly and annually | An operating budget built with management’s assumptions |
| Lender covenant reporting | On the lender’s schedule | Covenant calculations and the reporting package the lender asks for |
| Internal controls design and documentation | At setup, then reviewed | Approval workflows, segregation of duties and written procedures |
| AP and AR process and automation | At setup, then ongoing | Payables and receivables workflows, including automation where it fits |
| Inventory, costing and work-in-progress reporting | Monthly, where relevant | Reports that track inventory, production or job costs |
| Year-end file preparation for your external accountant or auditor | Annually | Schedules and supporting documents ready before fieldwork |
| Accounting software migration | Project | A planned move to a new system, including opening balances |
| Support hiring and training internal finance staff | As needed | Role definitions, training and review of the internal team’s work |
For each line, agree who prepares, who reviews and who approves the work. A controller may review entries prepared by someone else or make them directly. The scope should make that responsibility clear and identify the reporting output.
Does the outsourced controller do the work or only review it?
Our controllership team does the work. They make the journal entries monthly rather than only reviewing someone else’s, and they work inside your accounting system. The output at the end of each month is a package showing what is happening with cash flow, the balance sheet and the profit and loss.
Where you already have a bookkeeper, the controller sits above that role: reviewing, correcting, closing and reporting. Where you do not, bookkeeping can be included in the same engagement so there is no handoff gap between recording and review.
Ask how the provider allocates capacity around your close, covers absences and handles extra project work. Those commitments belong in the scope rather than being inferred from the title.
What do I still need to provide?
An outside controller cannot replace the people and authority inside the business. Plan for these to stay with you:
- Approval of payments and release of funds by the owner or a named officer
- Source documents: receipts, contracts, job and project information
- Access to bank, payroll and accounting systems
- Inventory counts or other physical checks on site
- Management’s assumptions for budgets and forecasts
- A named person who answers questions during the close
How does an engagement start?
The first months follow a predictable sequence, and the condition of the books decides how long it takes.
- Scoping. Entity count, transaction volume, systems, reporting audience and how far behind the books are.
- Catch-up, if needed. Where the books are behind, the first work is getting them current; see catch-up bookkeeping.
- Handover. Agree whether to transfer responsibilities together or in stages. Where both teams work during transition, identify one authoritative ledger and assign each posting and review task.
- Close calendar set. Reporting and review dates, upstream deadlines and an escalation process for missing information.
- Controls and reporting. Approval workflows documented, then the reporting package agreed with you and, where relevant, your lender or board.
When does a business need controller services rather than bookkeeping?
Bookkeeping is often enough for a single-entity, domestic, reasonably simple business whose owner can read the monthly package. Our controllership team treats any of the following as reasons to start at controller level:
- Multiple entities
- Manufacturing or inventory-heavy operations
- Cross-border activity
- Sales tax exposure across jurisdictions
- A lender, board or investors expecting regular reporting
- A carve-out with a transition services agreement you want to exit quickly
- No one internally who can interpret the numbers
A reasonable middle position is to start at the bookkeeping level and revisit if the business grows materially. We have made exactly that recommendation to clients who did not need more at the time.
What about after an acquisition or carve-out?
A new owner inherits the existing finance function and should reassess its responsibilities before changing staffing. In our post-close work, we have seen businesses replace full-time roles with scoped controllership and bookkeeping. That decision depends on the actual workload and reporting obligations, not the acquisition alone. Where we ran the quality of earnings beforehand, we already know how the accounting function works and where the gaps are.
Agree the accounting handover before changing the ledger or system. The plan depends on the transaction, entity continuity, opening balances and records that must remain available. If a system change is justified, see QuickBooks Online vs Desktop. Then set a firm monthly closing date. If the seller’s finance lead is staying for a transition period, use that window to transfer what they know. The post-close transition page covers the sequencing.
In one post-acquisition restructuring, our team took on hands-on controllership work with senior oversight, while local bookkeeping continued separately and the reporting was consolidated. The division of responsibilities was the useful design choice: local transaction knowledge stayed in place while hands-on controllership and consolidation had named owners.
What drives the cost of outsourced controller services?
We do not publish fees here. The scope is priced on:
- Number of entities and intercompany activity
- Monthly transaction volume
- How far behind the books are at the start
- Reporting frequency and audience
- Whether bookkeeping is included
- Inventory, costing or project accounting needs
Cleanup at the start costs more than a steady monthly close, so the first months are usually the heaviest.
What we do not do
Treewalk does not provide audit, review or other attest services, and we are not your auditor. We prepare the year-end files your auditor or external accountant works from. For tax we work alongside a specialist.
Frequently asked questions
What does an outsourced controller do each month?
Closes the books to a set date, makes the adjusting journal entries, reconciles the balance sheet, produces a reporting package covering cash flow, balance sheet and profit and loss, and raises what needs attention. Forecasting and controls work sit alongside that.
How is a firm different from hiring one fractional controller directly?
A firm can supply more than one level of preparation and review, but continuity still needs to be scoped. Ask who covers absences, how procedures are documented and whether the backup has access and capacity. Ask the same questions of an individual provider.
Do we still need this if we already have a bookkeeper?
Often yes. A bookkeeper records; a controller reviews, closes, reports and forecasts. Businesses that have only had a bookkeeper commonly have accurate data and no usable reporting.
Can you take over from our existing team gradually?
A staged handover can be scoped. Decide which tasks transfer on each date, who reviews them and which ledger remains authoritative during the overlap.
Is a comptroller the same as a controller?
The titles overlap, but statutory authority and governance responsibilities can differ by organization. See comptroller vs controller.
