Invoice entry and coding
Enter invoices from authorized source records and apply coding instructions supplied by the firm or client. Flag unclear descriptions, missing invoices, duplicate indicators or unsupported coding rather than guessing.

Client Accounts Payable Workflow Support for CPA Firms
Add defined AP preparation support to a client workflow: invoice entry, coding, vendor statement reconciliation and payment-batch preparation, scoped to the records and systems available. Your firm and its client retain approval authority and control over payment release.
A client workflow with clear approval boundaries
Move invoice preparation forward without moving payment authority
Accounts payable can create a separate queue inside a CPA firm’s client work: invoices arrive through different channels, coding needs to follow the client’s chart of accounts, purchase orders or receiving records may need to be matched, and vendor statements must tie back to the ledger. When these tasks are left until month-end, the firm may receive incomplete AP records just as it needs to close the books or prepare reporting.
Accounstone can discuss a defined preparation scope for those tasks, based on the client’s systems, available documents and the firm’s instructions. The purpose is not to take over the client’s financial authority. Invoice approvals, vendor decisions, payment release and the resolution of material accounting questions remain with the authorized client and responsible professionals.
Defined preparation tasks
What an AP support scope may include
The exact task list should be confirmed before work starts. These are possible preparation activities, not a blanket promise that every client system or invoice type is automatically in scope.
PO and supporting-record matching
Where the client uses purchase orders or receiving records, compare available documents and list mismatches for the designated approver. Disputed charges and commercial decisions stay with the client.
Vendor statement reconciliation
Compare vendor statements with AP ledger activity, identify missing bills or unmatched credits, and prepare an exception list for follow-up through the client’s approved process.
AP aging and payment-batch preparation
Maintain agreed aging schedules and prepare a proposed payment batch from approved records. An authorized client approver retains the decision to approve and release funds; bank access and payment execution are not part of this preparation description.
How the handoff works
Agree the evidence, reviewer and approval path first
A useful handoff begins with an agreed source of truth. Identify which inbox, document portal or accounting system supplies the invoice; what fields must be captured; which chart-of-accounts rules apply; whether purchase-order matching is required; and how exceptions should be returned. Also agree who may answer vendor questions, approve a bill, authorize a payment and resolve accounting or tax questions. The preparation team should not have to infer those responsibilities from the invoice itself.
AP intake checklist
- Confirm the client entity, accounting period, system and records included in the assignment.
- Provide the current chart of accounts, coding instructions and any approved vendor or PO references.
- Define how duplicate indicators, credits, unmatched items and missing documents are recorded.
- Identify the reviewer and the client-side person authorized to approve invoices and payments.
- Agree the expected output, due dates, file naming and process for changing the scope.
This approach also makes month-end review more useful: reconciliations can be tied to the AP ledger, unresolved items can be isolated, and reporting can identify which balances are supported versus awaiting clarification. If a task requires judgment outside the agreed instructions, it should be escalated to the responsible professional rather than resolved through an undocumented assumption.
From invoice receipt to reviewer handoff
A Practical AP Preparation Sequence
A repeatable AP workflow makes it clear which bills are ready for review and which need a client decision. The sequence should follow the client’s actual purchasing and approval process; not every client uses purchase orders or the same invoice intake channel.
1. Register the invoice
Capture the supplier, invoice number, invoice date, due date, amount, currency where relevant, client entity and source location. Retain the original document reference so the entry can be traced.
2. Check for duplicates and completeness
Compare supplier, invoice number, date and amount with existing AP records. Flag missing pages, unclear supplier details, duplicate indicators, credit notes and inconsistent totals rather than creating a second payable entry.
3. Apply documented coding
Use the client’s chart of accounts, entity and department or property dimensions where supplied. Route unclear business purpose, tax treatment or account classification to the firm or client for direction.
4. Match supporting records
Where purchase orders, receiving records or contracts are part of the process, compare supplier, quantity, rate and approval evidence. Record the variance and the person who must resolve it.
5. Prepare the review queue
Separate complete items from bills awaiting coding direction, missing support, dispute resolution or approval. A reviewer should not have to infer why an invoice is being held.
6. Reconcile and hand off
Compare vendor statements and AP aging with ledger activity, list credits and unmatched items, and return the agreed batch or schedule for authorized approval. Payment release remains with the client.
Exception log: fields worth retaining
For each held item, record the vendor, invoice reference, amount, affected entity, exception type, source evidence reviewed, decision required, responsible contact and current status. Common statuses include awaiting document, coding clarification, PO or receipt mismatch, vendor dispute, duplicate check and approval pending.
Do not change invoice dates, supplier bank details, coding policy or payment instructions to make a batch appear complete. Changes to vendor master data and payment instructions must follow the client’s own verification and authorization controls.
At period end, reconcile the AP control account to the supporting aging or subledger at the same cutoff date. Investigate old debit balances, unapplied credits, duplicate liabilities and invoices recorded in the wrong period. Any adjustment or write-off that requires accounting judgment should be presented to the responsible reviewer with its supporting evidence.

Scope, controls and review
Client accounts payable workflow support for CPA firms
Which accounts payable tasks can a CPA firm outsource?
Depending on the agreed scope and records available, preparation work may include invoice entry, coding to the supplied chart of accounts, purchase-order matching where applicable, vendor statement reconciliation, AP aging maintenance and payment-batch preparation. The firm and its client define the workflow and approval boundaries before access is granted.
Can Accounstone release payments or access client bank accounts?
Payment execution and bank access should remain with the client’s authorized personnel. Accounstone can discuss preparing an AP batch or schedule for review where the workflow and systems support it, but the client retains approval authority and release of funds.
Can AP support fit our existing accounting software?
The scope can be discussed around software the firm or client already uses, including supported accounting and bill-payment workflows. Confirm the exact platform, permissions, file structure and task boundaries before work begins. This service is not software implementation or vendor technical support.
How should exceptions and missing invoices be handled?
The handoff should separate completed preparation from missing source records, unmatched purchase orders, duplicate-invoice questions, vendor discrepancies and items needing client approval. The responsible firm or client decides how exceptions are resolved; the preparation process should not silently invent missing information.
Is this the same as general accounts payable outsourcing?
The underlying AP tasks can overlap, but this page is for CPA and accounting firms arranging support within a client-service workflow. The firm sets instructions, deliverables and review expectations. The general U.S. accounts payable service page describes the broader service scope for businesses.
What records should be available before AP preparation starts?
Useful inputs include vendor invoices, the chart of accounts and coding rules, purchase orders or receiving records where applicable, vendor statements, the AP aging report and the client’s approval workflow. The exact checklist depends on the systems and invoice types in scope.
How are differences between vendor statements and the AP ledger handled?
The comparison should identify missing invoices, credits, duplicate entries, timing differences and other exceptions using the available source records. The responsible firm or client decides how disputed items are resolved; the workflow records the evidence and next action.
Can you prepare AP aging schedules and proposed payment batches?
Where the records and agreed workflow support it, preparation can include AP aging schedules and a proposed batch for an authorized reviewer. The client’s designated approver retains payment approval and release, and the scope does not imply bank access.
Can AP support cover more than one client or entity?
Yes, when the entities and tasks are identified in the scope. Each client or entity may have different coding rules, approval steps, software, vendor records and due dates, so those differences should be documented before work begins.
Who decides how an unclear invoice should be coded?
The firm or client provides the coding policy or instruction. If a description, account, entity or supporting document is unclear, the item should be flagged for a decision rather than assigned based on an unsupported assumption.
