Deadlines creep up, the records are messy, and the worry is that something gets filed late or wrong while the business keeps moving. An accounting contract gives both sides the same written basis for the work, so the accountant can ask for what’s needed and the client can see what’s getting handled. The document runs through the day to day and year end services, payment timing, privacy, and how the engagement ends, with headings in Space Grotesk over a deep maroon and a teal accent for the acceptance point.

The opening sections explain the split between ongoing bookkeeping style support and year end accounts and returns, tied back to the proposal that was accepted, then spell out what information has to arrive each month or quarter and what happens when extra work appears. Payment language stays specific about recurring periods, 7 day invoice terms, and what gets paused if an account goes overdue, and the confidentiality section covers sharing with bodies like HMRC and Companies House and how records and working papers get handled after the work ends. The later sections confirm the accountant’s independent status, how rolling renewals and notice are agreed around live deadlines, and where responsibility sits if missing information or delayed approvals cause penalties.

  • We will do the day to Frames the day to day and year end work against the accepted proposal, and states what each side has to do to keep filings on time.
  • What we do Lists the accounting & tax services covered and names the monthly or quarterly records and cut offs needed to deliver them.
  • Payment States that billing happens at the start of each period, invoices are due within 7 days, and deadlines may be paused while fees are overdue.
  • Keeping things private Covers confidentiality, when information gets shared to do the work, and what happens to records and working papers when the engagement ends.
  • Ending the agreement Explains notice, payment up to the end date, and the handover information provided once the account is up to date.

Once the terms match how the practice actually works, you send the contract and the client signs online, leaving you with an agreed scope, billing cadence, and a clear handover path if the engagement ends.

We went from spending hours on every proposal to creating fully customized ones in under 5 minutes. That's not an exaggeration - we timed it.

What to include in an accounting contract

PartWhat it covers

We will do the day to

Defines the day to day and year end work by reference to the accepted proposal, and sets expectations for keeping filings on time.

What we do

Describes the tax preparation and accounting services that may be included, and the records the client supplies each month or quarter, including how extra work gets confirmed.

Payment

Explains recurring billing at the start of each period, 7 day payment terms, and when work tied to submissions may pause if invoices go overdue.

Keeping things private

Covers confidentiality, necessary sharing with parties like HMRC and Companies House, and how records, outputs, and working papers are handled at the end of the work.

How we are set up

States the practice works independently, keeps responsibility for its own tools and obligations, and explains authority to speak to HMRC or Companies House while the client remains the legal filer.

Ongoing work

Explains the recurring renewal each period, how notice is agreed in writing around live deadlines, and what both sides confirm during offboarding.

If something goes wrong

Sets out how missing records or delayed approvals affect accuracy and timing, and limits liability for penalties and indirect losses tied to late or incomplete information.

Ending the agreement

Confirms either side can end by notice and covers cooperation until the end date, final fees and committed costs, and handover once the account is settled, with a Signature for acceptance.

Who it is for

Accounting and tax practices taking on recurring client work, and owner managed businesses hiring an accountant to handle filings and ongoing compliance.

The contract in full

We will do the day to day running work (like VAT and payroll where included) and the year-end work (like accounts and tax returns where included) in line with the proposal you accepted, using the records you give us and the access you grant us.

This agreement sets out how we will work together, what we each need to do to keep filings on time, and how billing and handover works.

What we do

We will deliver the accounting and tax services listed in the proposal you accepted. This usually covers a mix of bookkeeping support, VAT quarter close and submission, payroll runs and RTI filings, year-end accounts, corporation tax computations and returns, Self Assessment returns, and Companies House filings, depending on what you have asked us to take on.

To keep things running smoothly, you will send us what we need each month or quarter (bank feeds or statements, sales and purchase invoices, and any payroll changes) by the cut-off we agree for that period. If you ask us to pick up extra work, clean up earlier periods, or deal with something unexpected, we will confirm what is changing and the fee before we start.

Payment

Because this is recurring work, we invoice at the start of each period for the work in that period. Nothing is paid up front beyond that period’s invoice. Each invoice is payable within 7 days of its date.

If an invoice goes unpaid, we will tell you what is overdue and ask you to bring the account up to date. While an invoice remains overdue, we may pause work that depends on us filing or submitting (for example a VAT return, payroll submissions, or a tax return) because we cannot keep taking on deadlines without payment being kept current. If a deadline is close, we will flag the risk and agree a plan with you.

Keeping things private

We both come across private information while we work together. We will keep your business and personal information confidential, and you will do the same for ours, unless either of us needs to share something to do the work properly (for example with HMRC, Companies House, payroll or pension providers, or our software providers) or where we are required to share it.

When the work ends, you still own your underlying records. If your fees are up to date, you can request copies of the accounts, returns, and working papers we have produced for you. We will return or provide copies in a practical format, and we will keep our own working files for our records.

How we are set up

We work for you as an independent accounting and tax practice, not as your employee. That means we decide how to organise our time and the order we do tasks in, as long as we meet the agreed deadlines and deliver what you have asked for.

We are responsible for our own taxes and insurances, and we use our own tools and software. Your team remain responsible for running the business day to day and for approving key decisions and figures. Where you need us to speak to HMRC or Companies House on your behalf, you will give us the authority we need, and you remain the taxpayer and the legal filer.

Ongoing work

This engagement runs on a recurring basis and renews each period automatically. We invoice at the start of each period, and the work for that period is covered by that invoice.

Either of us can end the recurring arrangement by giving notice. We will agree the notice period with you in writing, because it depends on what deadlines are in play (for example a VAT quarter close, a payroll run, or a year end). If you give notice, we will tell you what is due next, what we still need from you, and what we can reasonably complete before the end date. If we give notice, we will do the same so you have time to move to another adviser.

If something goes wrong

We take care with the filings and submissions we prepare, but we can only work with the information and access you give us. If figures are missing, records are wrong, or approvals are delayed, it can affect the accuracy of what we file and whether it goes in on time. We will flag issues as we find them and tell you what we need to fix them.

We are not responsible for penalties, interest, or costs that come from late or incomplete information, late approvals, or decisions you make after we have advised you. We also cannot cover losses that are indirect or not reasonably foreseeable, like knock-on business costs from a cashflow squeeze or a lost deal.

Ending the agreement

Either of us can end this agreement by giving notice, and we will confirm the end date in writing. Until that end date, you agree to keep sending the records and answers we need so we can either complete the current deadlines or hand over cleanly.

You will pay for work done up to the end date, including any work already completed but not yet invoiced, and any unavoidable costs we have committed to on your behalf. Once your account is up to date, we will provide reasonable handover information to your new accountant if you ask us to, and if you have given them permission for us to speak to them. If HMRC or Companies House write to you about work we filed, you will send it to us as soon as it arrives so we can help you respond.

Questions about this contract template

What should an accounting contract include?

An accounting contract normally states the services included, what records and access the client must provide, how and when fees are billed, confidentiality, and how the engagement ends. This template also covers recurring periods, pausing submission work when invoices are overdue, and handover at the end.

What do accountants usually need from a client each month or quarter?

Most engagements rely on timely records such as bank feeds or statements, sales and purchase invoices, and any payroll changes. This contract makes that expectation explicit and ties it to an agreed cut off for the period.

Can an accountant pause filing a VAT return or payroll submissions if an invoice is unpaid?

An accountant can set terms that allow pausing work that depends on filing or submitting while fees remain overdue. This contract also says the risk gets flagged if a deadline is close and a plan is agreed.

Will an accountant deal with HMRC or Companies House for me?

An accountant can liaise with HMRC or Companies House when the client grants the authority needed. This contract also states the client remains the taxpayer and the legal filer, even when the accountant acts on their behalf.

Who is responsible for penalties if records are late or figures are wrong?

Responsibility usually depends on what caused the issue and what information was provided. This contract says the accountant can only work with the records, access, and approvals provided, and it limits liability for penalties and costs caused by late or incomplete information or delayed approvals.

How do you end an ongoing accounting arrangement and handle handover?

Either side can end by giving notice, with the notice period agreed in writing based on live deadlines. This contract also covers paying for work done up to the end date and providing reasonable handover information once the account is up to date.
