Accounting services operating workflow: acceptance to filing

A dependable accounting services operating workflow is a sequence of decisions about what enters, who decides, what gets checked and what evidence proves completion. Start at acceptance, then follow the condition that matches the file; move forward only when the decision is recorded. The same controls apply to ordinary records and awkward work arriving near a deadline: every step needs an owner and an escalation route.

If this is a new client or service

Create one master record for the legal entity, contacts, authority, service, periods, deadlines, tax registrations, software and engagement version. Use it to connect the client with each period of work and the decisions that follow through preparation, review, approval and filing.

Complete applicable acceptance, identity, AML, conflict, competence and capacity checks before work starts. The rules and compliance guide sets out relevant checks; log each applicable decision against the master record so it shows why work may proceed and who owns the decision for this client and service.

The HMRC standard for agents expects agents to act with integrity and professional competence, keep contemporary records of what they advise clients and when, and take reasonable steps to ensure third-party input, including software, gives accurate results. Turn each applicable expectation into an owner and a file record.

Accountants are covered by the Money Laundering Regulations, and every covered business must be monitored by a supervisory authority. This may be a professional body such as the Association of Accounting Technicians or the Institute of Chartered Accountants in England and Wales, or HMRC for accountancy service providers not supervised by a professional body. Record the applicable supervisor before accepting work.

Tax advisers who interact with HMRC on behalf of clients must also register for an agent services account. Add the agent reference and each client's authorisation status to the master record, using the HMRC agent status check for the relevant authorisations. Rule of thumb: do not begin until acceptance checks, supervision and authority are recorded.

If a filing date is not yet controlled

Record the statutory or agreed due date, its authoritative source and the date checked, then work backwards through client cut-off, preparation, queries, technical review, client approval and submission. Allow capacity for correction so internal completion comes before, rather than coincides with, the external deadline.

For a private limited company, GOV.UK sets out the main filing dates. Carry these alongside VAT and Self Assessment dates in the same register. The entries below give the filing deadlines to track, with the relevant authority beside each one. They are general dates and not every company follows them: a newly incorporated company's first accounts, and companies that pay Corporation Tax in instalments, run to their own timetable, so check the individual case before relying on the register.

Keep one controlled deadline register. For every change, record its source, date, editor and notification to affected owners. A calendar copied between systems can drift without anyone noticing, so keep the authoritative entry under control. Rule of thumb: plan from the verified due date, not from a copied calendar.

If records arrive incomplete or through an unapproved channel

Tell the client which documents, formats, periods and approvals are required. When records arrive, log their completeness, duplicates, legibility, entity and period. Quarantine information received through an unapproved channel, then move it using the authorised process so its route into the file is clear.

Create an exception list for missing evidence, unexplained transactions and inconsistent balances. Give each item an owner, consequence and latest resolution date; do not quietly turn a client assumption into a ledger fact. Rule of thumb: keep each exception visible until it has an owner and a recorded resolution.

If preparation raises a judgement or review question

Link entries and adjustments to their source. Record estimates, classifications and positions with the preparer, reasoning and date. Use templates that prompt thought rather than ticks that can be completed without examining the file. A quality checklist can grade each file red, amber or green.

Keep routine processing separate from technical decisions. Escalate unfamiliar questions about an entity, tax, reporting, industry or cross-border matters to someone whose competence has been evidenced for that task. This makes the decision-maker and the basis for their involvement traceable in the file.

Set the required check for each task: self-check, second-person review or specialist approval. The reviewer should inspect source evidence, reconciliations, unusual movements, prior-period consistency, unresolved queries and output presentation, then record findings, corrections and closure. Where staffing and risk permit, use the team roles to avoid one user preparing, approving and submitting high-consequence work; if roles cannot be separated, document an alternative safeguard. Rule of thumb: match the review to the consequence and record how every finding was closed.

If the work is ready for client approval and filing

Give the client a stable version, a clear explanation and an approval deadline. Settle the approval terms in the commercial contracts, and record who had authority to approve and any condition attached. If figures change after approval, obtain approval again for the changed output before proceeding.

Submit through the correct authorised account and preserve the exact submitted version, timestamp, response and acknowledgement. Directors must approve company accounts before filing, and Companies House is moving to software-only filing of accounts, so check that the practice software can produce and submit them. An acceptance response does not itself prove the filing met its deadline. Rule of thumb: retain evidence of both the approved version and the actual submission.

If filing is complete or the engagement ends

Confirm that queries are resolved, records are filed, the client receives the agreed outputs and access is correct. Schedule the next period and the retention action required by the practice's data protection approach. Close the current task only after these operational steps are visible in the record.

Record errors and near misses by cause and consequence, then test the corrective change. Revisit the workflow after a missed cut-off, rejected submission, material correction, supplier outage or service change. The process is complete only when another competent person can reconstruct the work from its evidence.

At termination, inventory unfinished work, future deadlines, records, authority and system access. Agree what transfers and remove permissions promptly. Include billing and complaints in the trace, showing which agreed output generated a charge and where a client can challenge service or price.

Operational closure does not erase a live complaint, an unresolved correction or a duty to preserve relevant material. Keep these matters visible with the records and access arrangements being handed over. Rule of thumb: finish only when completed work and any unresolved duties remain reconstructable.
