An accountancy engagement letter should make the proposed relationship usable. It explains what the provider will do, what you must supply and where the agreement's boundaries lie. Read the letter, service schedules and attached terms together before assuming a quotation covers every financial task.
The aim is not to master contractual language. It is to know how the work will run and to resolve terms that affect your business before relying on them.
Identify the client and the work
Check which person or entity is engaging the firm. A company's accounts and a director's personal tax return are different pieces of work. If several companies or individuals are involved, identify each scope rather than assuming one name covers the group.
Check the periods and start date too. Does the provider take over ongoing work, complete an outstanding year or rebuild historical records? Those commitments can have different information needs and fees.
Replace broad labels with deliverables
“Accounts and tax” is not enough to run a relationship. Ask whether the service includes bookkeeping, reconciliations, annual accounts, specific tax returns, payroll, VAT, management reports or advice meetings.
For each included task, establish the output and frequency. A monthly fee does not necessarily include monthly processing; a management report does not necessarily include a meeting to interpret it.
ICAEW’s current engagement-letter guidance emphasises tailoring terms to the actual service. That is a useful reason to query wording that does not match your discussion, rather than assuming a standard document must describe the arrangement accurately.
Agree the information and approval process
Record how documents are supplied, which records are expected and when questions need answers. Ask how incomplete information affects the timetable.
An illustrative company agrees monthly reporting but sends contractor bills several weeks late. The engagement needs a realistic document cut-off, a way to identify missing costs and an explanation of any estimates. A reporting promise without those dependencies may be unworkable.
Check who reviews draft accounts or returns, how approval is given and what happens if figures change afterwards. An email saying “received” should not be mistaken for approval.
Make responsibility visible
| Task | Point to agree |
|---|---|
| Record collection | Who gathers missing invoices and explanations? |
| Preparation | What does the provider prepare and review? |
| Deadlines | Who tracks dates and escalates risks? |
| Approval | Who within the business authorises the output? |
| Submission | Who files and checks acceptance? |
| Payment | Who arranges and checks payment to the authority? |
For company directors, outsourcing day-to-day tasks does not remove the responsibilities described in GOV.UK's director guidance. The letter should support oversight rather than leave you assuming the provider has taken over the entire role.
Read exclusions as a work-allocation list
Exclusions are not automatically a problem. They show where another arrangement may be needed. Common matters to clarify include historical cleanup, enquiries, complex transactions, additional entities, software migration and specialist advice.
For example, a package may prepare a tax return but exclude an HMRC enquiry. Ask how that situation would be scoped and charged. Do not assume the original fee includes unlimited representation.
Identify any essential task excluded by every adviser. That gap needs an owner before the work starts.
Understand fees and changes
Check the charging basis, payment schedule and what triggers additional charges. Ask how extra work is estimated and approved. Growth in transactions or employees may justify a review, but the process should be understood in advance.
Find out whether software subscriptions, meetings and routine queries are included. Keep government charges distinct from the provider's fees where relevant.
If the scope changes, ask for the revised agreement to be recorded. A casual conversation about “helping with forecasts” can otherwise create different expectations about the work included.
Check access, complaints and exit terms
Establish who controls software, how records can be retrieved and how a handover works. Read notice requirements and arrangements for unfinished work. Ask which deadlines remain the provider's responsibility during departure and which transfer to you or the new adviser.
Check the complaint route and any terms affecting liability or use of reports. If a significant clause is unclear, request an explanation and appropriate independent advice rather than guessing its legal effect. There is no universal notice period or handover entitlement stated here.
Turn the agreement into a short working schedule
Keep a page listing tasks, contacts, information dates and approval routes. Revisit it after hiring, adding a company or changing reporting needs. This makes the detailed agreement easier to use without replacing its terms.
