Outsourced Accounting Services

Accounting outsourcing places recurring records, reconciliations and close preparation under defined delivery ownership. ARDEM manages the agreed work and follows unresolved items through correction or review. Your finance leadership retains accounting policy and the designated approvals.

Organize delivery around your accounting calendar. Daily work keeps records current. Weekly reviews resolve differences and missing support. Period-end delivery brings together the reconciliations, schedules and supporting records your reviewers need.

The operating model can include documented procedures, processing queues, quality checks, exception tracking, follow-up and reporting so accounting work remains visible and measurable as volumes change.

How accounting outsourcing works

From source records to
review-ready accounting.

ARDEM manages the agreed processing, reconciliations and exception follow-through. Your finance team retains accounting policy and designated approvals.

Scope, controls and deliverables are agreed for each engagement.

Your approved systems

Source records

Invoices, bank activity and supporting documents enter the agreed workflow.

The starting point is your operation, not a required platform replacement.

ARDEM manages delivery

Process, reconcile
and verify

Prepare accounting records, apply agreed checks and reconcile the work before handoff.

Work that meets the completion criteria moves to delivery. Unresolved items stay visible.

Your team receives

Records ready
for review

Agreed reconciliations and supporting schedules, with a clear view of what is complete.

Open items are reported separately, with an owner and next action.

When an exception arises

Follow-through,
not another backlog.

ARDEM investigates and follows through

Trace missing support, coding issues or reconciliation differences. Resolve authorized items and verify the result.

Your decision, when required

Items outside ARDEM’s authority go to your designated owner. ARDEM tracks the response and resumes the agreed work.

Resolved items return to validation. Items awaiting a decision remain open, rather than being counted as completed work.

Improve the operation as it runs.

Review delivery and recurring exceptions. Agree practical changes, implement them and compare performance with the baseline.

Find the Right Accounting Scope

Choose the Accounting Operating Model That Fits the Work

Additional staff can fit an operation that already has effective procedures and supervision. Software can fit standardized work when an internal owner can maintain the rules and resolve exceptions. Managed accounting combines the required expertise, controls, technology and delivery ownership.

These are not mutually exclusive choices. ARDEM can build and operate a solution within your systems, connecting automation and specialist review where they improve the process.

Compare implementation, integrations, recurring processing, management, quality review, exception follow-through and retained internal effort on the same basis. Savings and delivery commitments should reflect the actual scope rather than a blanket claim about outsourcing.

For a coordinated operation across AP, AR and related finance processes, explore finance and accounting outsourcing. For a defined ledger requirement, see general ledger accounting services.

Managed accounting works best when expertise, controls, technology and exception ownership are designed around the required output. ARDEM can operate within approved client systems and add automation where it supports reliable execution without requiring a platform replacement.

Automated Matching Still Needs a Resolution Process

A suggested match can reduce review effort. An unmatched transaction still needs an explanation, supporting evidence, and an authorized next step. Completion should distinguish reconciled records from open differences awaiting research or a client decision.

ARDEM can organize source records, apply agreed checks, investigate differences, obtain missing support, and prepare permitted corrections or review schedules within scope. Open items retain an owner, next action, age, and review status.

For manual processes, we can design a repeatable reconciliation workflow and introduce suitable matching or validation automation. For an established system, we assess the remaining work and manage the agreed process through review-ready output. Accounting judgments, write-offs, journal approvals, and other retained decisions follow your documented authority model.

Supplier statements require a distinct workflow. See vendor statement reconciliation services for matching vendor statements against AP records.

Recurring outputs can include transaction records, reconciliations, supporting schedules, workpapers, journal support and reporting preparation. The required format and review criteria are defined for the accounts and systems in scope.

Assurance With a Defined Scope

Request current assurance documentation for the proposed service. Confirm the entity, system and coverage period with your security team. Infrastructure assurance alone does not establish assurance over the accounting operation.

Review and Approval Evidence

Record posting permissions, reviewer responsibilities and the evidence required for adjustments. ARDEM follows the agreed controls and keeps unresolved items visible. Independent assurance, tax advice and regulatory sign-off are separate responsibilities.

Frequently Asked Questions

What accounting services can be outsourced?

Companies can outsource recurring accounting activities such as bookkeeping, accounts payable, accounts receivable, reconciliations, general ledger support, expense processing, transaction processing, month-end support and financial reporting preparation. The appropriate scope depends on which activities can be clearly documented, controlled and managed externally.

What is accounting outsourcing, and what does accounting process outsourcing include?

Accounting outsourcing assigns agreed accounting activities to an external provider. Accounting process outsourcing includes the recurring workflows around that work, such as processing, quality checks, exception resolution, follow-up and operational reporting, under documented procedures and business rules.

What Determines the Cost of Accounting Outsourcing Services?

Price depends on the accounts and activities included, transaction volume, number of entities, source-record quality, reconciliation complexity, systems, review requirements and reporting calendar. Backlog cleanup, implementation and integrations should be distinguished from recurring processing and management. Representative records help define a proposal that reflects the actual work and retained internal effort.

Can ARDEM build an accounting workflow if our process is not fully documented?

Yes. We can begin with the output you need and map the inputs, accounting rules, controls, system access and review responsibilities. The implementation plan identifies missing records and decisions, tests the workflow and defines acceptance before expanding production.

Can ARDEM work within our existing accounting or ERP system?

Yes. Work can be carried out inside an approved accounting environment or connected through APIs, scheduled exchanges or secure files, depending on the requirement. Implementation covers field mapping, reference data, authorization, validation, rejected output and confirmation that the destination accepted the information.

Does outsourcing accounting mean giving up financial control?

No. A managed accounting outsourcing model can allow the client to retain accounting-policy ownership, approval authority, banking authority and financial decision-making while the provider manages agreed operational accounting activities. Other delegated activities, including payment preparation or authorized execution where contracted, follow the documented control model.

How can accounting work transition around our month-end close?

Map the recurring tasks, source systems, deadlines and dependencies against your close calendar. Begin with a defined scope and review outputs against agreed requirements before expanding. ARDEM can organize the transition around your reporting cycle, with documented handoffs, exception paths and completion checks for the work included in the managed service.

How are missing information and reconciliation exceptions resolved?

Define the supporting records, validation rules and resolution steps for each recurring activity. ARDEM investigates discrepancies and resolves items within the agreed operating rules. Questions requiring client judgment are escalated to the assigned owner, with open items and their age included in reporting. This helps finance leaders see what remains outstanding and where recurring delays originate.

How should we measure an accounting outsourcing service?

Track completion against the close calendar, turnaround, backlog, exception resolution and rework for the agreed scope. Compare service cost with internal effort and operational reliability using consistent definitions. ARDEM can provide reporting against the agreed measures so your finance team can evaluate delivery and identify further improvement opportunities.
