Outsourced legal cashiering is a legitimate and increasingly common arrangement for UK law firms. Nothing in the SRA Accounts Rules 2019 prohibits a firm from using an external provider to carry out the day-to-day cashiering function. What the Rules make clear is that the firm's regulatory obligations do not travel with the work. The COFA remains responsible; the provider is an operational resource, not a regulatory shield.
This guide covers what outsourcing can and cannot transfer, how the SRA's framework applies, what your COFA should check before signing a provider contract, how to compare the full cost against an in-house cashier, and how provider fees are treated for tax.
If you are unclear on what a legal cashier actually does day-to-day, read our companion guide on what does a legal cashier do and the SRA requirements before evaluating whether to outsource the role.

What outsourced cashiering actually means, and what it is not
Outsourced legal cashiering means the firm contracts with a third-party provider to perform the day-to-day cashiering function: ledger posting, payment processing, bank reconciliations, interest calculations and compliance reporting. The firm's client account remains open in the firm's name. The firm continues to receive and hold client money. All of the SRA Accounts Rules 2019 obligations that flow from holding client money remain with the firm.
The TPMA distinction: outsourcing the function versus not holding client money at all
It is critical to draw a clear line between outsourced cashiering and a third-party managed account (TPMA). These are not variations of the same arrangement; they are opposite models with different regulatory consequences.
A TPMA under SRA Accounts Rules Rule 11 is a structure in which the firm does NOT receive or hold client money at all. Rule 11.1 permits a TPMA only where using the account does not result in the firm receiving or holding the client's money. The condition that the provider must be an FCA-authorised payment institution (operating an escrow arrangement) sits in the SRA Glossary definition of "third party managed account". Because the firm never holds the client money, the five-weekly reconciliation requirement (Rule 8.3) and the accountant's report trigger (Rule 12.1) do not apply. The TPMA changes the firm's cost structure significantly: bank charges on a client account, the Rule 12 report cost, and the cashiering overhead all potentially disappear, though the disbursement-funding model and client experience change too.
Outsourced cashiering is the opposite premise. The firm still operates its own client account. It still receives and holds client money. It still owes every obligation under the SRA Accounts Rules 2019. The Rule 8.3 five-weekly reconciliation, the Rule 12.1 accountant's report trigger, the Rule 3.3 banking-facility prohibition, the Rule 7 interest duty, the Rule 4.2 prompt-allocation obligation on mixed payments, the Rule 4.3 bill-before-transfer requirement, the residual balance rules in Rule 5.1(c): all of these sit with the firm regardless of the cashiering model. The provider performs the mechanics; the firm and its COFA carry the liability.
This distinction matters for cost comparison: a firm on the outsourced-cashiering model carries the Rule 12 accountant's report cost and the underlying client-account bank charges alongside the provider fee. A firm that moves to a TPMA may remove those costs entirely, though it takes on a different operational model. For firms exploring the no-client-account alternative, see our guide to running a law firm without a client account and our dedicated guide to third-party managed accounts for law firms.
What the SRA requires when you outsource
COFA accountability does not transfer (SRA Code para 2.3)
The COFA (Compliance Officer for Finance and Administration) is appointed under the SRA Authorisation of Firms Rules and carries primary responsibility for compliance with the SRA Accounts Rules 2019. Outsourcing the cashiering function to a third party does not transfer COFA accountability.
SRA Code of Conduct for Firms paragraph 2.3 (version in effect from 11 April 2025) is explicit: "You remain accountable for compliance with the SRA's regulatory arrangements where your work is carried out through others, including your managers and those you employ or contract with."
This means the COFA must:
- Set and enforce the service-level framework governing the provider's work.
- Sign off Rule 8.3 reconciliations. The sign-off obligation does not delegate to the cashiering provider; the COFA must review the three-way reconciliation and satisfy themselves it is accurate before signing.
- Retain oversight of the Rule 12 accountant's report cycle, including ensuring the report is obtained within six months of the accounting period end where the trigger applies.
- Take responsibility for any SRA notification obligation that arises from a breach the provider caused. If the provider makes an error that constitutes a material breach of the Accounts Rules, it is the firm's breach and the COFA's decision whether to self-report.
A provider that causes a client account breach does not absorb the regulatory consequence. The SRA's sanction, where one follows, falls on the firm.
SRA Accounts Rules obligations that remain with the firm
The following obligations sit with the regulated firm regardless of who performs the day-to-day cashiering work:
Client account (Rule 3). Client money must be held in a properly designated client account at a bank or building society branch in England and Wales. The outsourced provider does not hold the account; the firm does. The account remains open in the firm's name.
Banking-facility prohibition (Rule 3.3). Every payment in or out of client account must relate to the delivery of regulated services. The provider executes these payments, but if a payment breaches Rule 3.3, the breach is the firm's.
Mixed payments and prompt allocation (Rule 4.2). Where a single receipt is part client money and part the firm's own money, the funds must be allocated promptly to the correct ledgers. The standard is promptness; there is no fixed day-count. The provider can perform the mechanics, but the obligation and any delay are the firm's.
Bill before transferring costs (Rule 4.3). Before the firm's costs are transferred out of client account, a bill of costs or other written notification must be given to the client. The provider must operate within this constraint; a provider that transfers costs without a prior bill causes a Rule 4.3 breach, which is the firm's breach.
Interest (Rule 7). The firm must account to clients for a fair sum of interest on client money held. The provider may calculate and administer this, but the obligation and any client-facing liability sit with the firm.
Five-weekly reconciliation (Rule 8.3). Ledger totals must be reconciled to the cash book and the bank statement at least every five weeks, signed off by the COFA or a manager. A provider that delivers the completed reconciliation for COFA sign-off satisfies the mechanical requirement; the COFA's scrutiny and sign-off remain non-delegable. For a full breakdown of the reconciliation requirements, see our COFA monthly checklist for UK law firms.
Accountant's report (Rule 12.1). If the firm has held client money at any point in the accounting period, a report by a qualified accountant is required within six months of the period end. The Rule 12.2 exemption (average balance not exceeding £10,000 AND maximum not exceeding £250,000) applies on the usual terms regardless of whether a cashiering provider is used. The outsourced model does not remove the report requirement; it changes only who does the underlying cashiering work that the report examines.
Residual balances (Rule 5.1(c)). An unclaimed client balance of £500 or less on any one matter may be paid to a charity without prior SRA authorisation, provided all conditions are met (reasonable steps taken to return the money, a central register kept, the charity's number recorded). For amounts over £500 the firm must obtain the SRA's prior written authorisation. The provider may identify these balances; the decision to apply Rule 5.1(c) and the associated record-keeping sit with the firm.
Records, data and provider exit
The SRA Accounts Rules require client account records to be kept for at least six years. An outsourced arrangement must preserve the firm's ability to produce those records at any time, including if the provider relationship ends.
In most outsourced cashiering models the provider accesses the firm's existing practice management system remotely rather than operating a separate ledger. This means the transaction data typically remains in the firm's own PMS, which is the best-case scenario. Confirm this contractually nonetheless. The contract should address:
- Data ownership (who owns the records generated during the relationship).
- Data export in a usable format (structured data, not a PDF dump that cannot be imported into a successor system).
- Continuity of access during a transition period if the relationship ends.
- Deletion obligations at contract end (any copies the provider holds of firm data should be deleted on a defined timeline, with written confirmation).
Because the provider accesses personal data (client names, matter details, financial information), a data-processing agreement compliant with UK GDPR Article 28 is required. The firm is the data controller; the provider is a data processor. The firm is liable for the processor's acts as data controller.
Selecting a provider: the compliance checklist
The due-diligence checklist below is the tool the COFA should complete before contracting with any provider. Each item maps to a specific regulatory risk the firm retains under paragraph 2.3 of the Code. This is not a recommendation of any particular provider; the decision belongs to the firm.
| # | Check | Regulatory hook |
|---|---|---|
| 1 | Professional indemnity or errors-and-omissions cover. Confirm the level, whether it responds to cashiering errors that expose the firm to SRA sanction, and whether the firm is a named beneficiary. | Para 2.3: the firm bears the SRA sanction even if the provider caused the error. |
| 2 | Working knowledge of SRA Accounts Rules 2019. Ask the provider to explain how they handle mixed payments (Rule 4.2, allocate promptly), the prohibition on moving firm costs out of client account without a prior bill (Rule 4.3), and residual balances (Rule 5.1(c), the £500 charity threshold and SRA prior written authority above £500). | Rules 4.2, 4.3, 5.1(c): mechanical errors here are the firm's breach. |
| 3 | Reconciliation sample. Request a sample three-way reconciliation (client ledger totals, cash book, bank statement) in the format Rule 8.3 requires. The COFA must be able to review, understand and sign it without the provider explaining it. | Rule 8.3 sign-off is non-delegable. |
| 4 | Practice management software compatibility. Confirm the provider can access and operate within the firm's existing PMS. Ask which PMS platforms the team works with and how the integration is tested before go-live. | Operational: errors from unfamiliarity with the PMS breach Rules 4.2 and 4.3. |
| 5 | SLA and breach-notification protocol. The contract must require the provider to notify the firm immediately of any error or potential breach it identifies, with enough detail for the COFA to assess whether a report to the SRA is required. | COFA's self-report obligation under SRA Authorisation of Firms Rules. |
| 6 | Data-processing agreement (DPA) under UK GDPR. The provider processes personal data as a data processor. The firm remains the data controller. Confirm whether the provider uses sub-processors (for example, offshore bookkeeping teams) and whether international transfer safeguards (UK IDTA or equivalent) are in place. | UK GDPR Article 28: the firm is liable for the processor's acts. |
| 7 | Exit and data-portability terms. Confirm data can be exported in a usable format at contract end, records remain accessible during a transition period, and the provider's obligations at contract termination are clearly specified. | Six-year records-retention obligation under the SRA Accounts Rules. |
| 8 | References from firms of comparable size and practice type. A provider experienced with residential conveyancing practices may not be right for a criminal-legal-aid firm. Operational complexity differs materially by practice area. | Para 2.3 competency assessment. |

Cost versus in-house: a comparison framework
Full-cost template
A genuine cost comparison involves the full cost on both sides of the decision, not just the provider's headline monthly fee against an in-house salary. The template below is the tool; the figures must come from the firm's own numbers.
In-house cashier (annualised)
| Cost line | Notes |
|---|---|
| Gross salary | Market range varies by experience and geography |
| Employer NIC | 15% on salary above the £5,000 secondary threshold, from 6 April 2025 |
| Pension auto-enrolment | Minimum 3% employer contribution on qualifying earnings |
| Recruitment or agency fee (amortised) | Typically 10 to 20% of first-year salary; treat as a one-off |
| Training and CPD | SRA Accounts Rules updates; PMS training; ILFM qualifications |
| Cover during absence | Agency cashier cost or overtime premium during leave and sick periods |
| PMS licence cost attributable to cashiering module | Include only if separately charged |
| Total in-house cost |
Outsourced provider (annualised)
| Cost line | Notes |
|---|---|
| Provider fee | Include 20% VAT where the firm is not VAT-registered (irrecoverable cost). For a VAT-registered firm making predominantly taxable legal supplies, input VAT on the fee is recoverable and the VAT is cost-neutral |
| PMS integration cost | One-off or ongoing depending on platform |
| Retained client account bank charges | These remain regardless of the cashiering model; the firm still holds client money |
| Rule 12 accountant's report fee | This remains regardless of the model; the report is triggered by the firm holding client money, not by who does the cashiering |
| Total outsourced cost |
The risk dimension
The cost template does not capture the risk dimension directly, but the comparison is incomplete without it.
In-house risk. An employee has employment-law protections. If performance falls short, exit is slow and potentially costly. A sole in-house cashier creates a single point of failure during absence or departure; the firm needs a contingency plan (locum cashier, partner cover) that itself carries a cost.
Outsourced risk. The contract can typically be exited on notice, removing the employment-law constraint. But transition risk must be managed: moving ledger history, access credentials and reconciliation records takes time and creates an operational gap during any provider switch. The due-diligence checklist above, in particular the exit and data-portability items, mitigates this risk before the contract is signed.
Some providers cite savings of 20 to 30% on in-house salary costs, or up to 50% in some cases. These figures are not independently verified and will vary materially by firm size, location and existing staffing structure. The template above is the tool; apply it to the firm's own numbers rather than relying on headline estimates.
Tax treatment of cashiering provider fees
Deductibility: the wholly and exclusively test
Fees paid to an outsourced cashiering provider are a revenue expense incurred for the purposes of the firm's trade. For an unincorporated firm (sole practitioner, partnership or LLP), the deduction is governed by ITTOIA 2005 s.34: expenditure is deductible if incurred "wholly and exclusively for the purposes of the trade, profession or vocation". For a company or ABS, the equivalent is CTA 2009 s.54.
A cashiering fee is an ordinary recurring management expense of running the practice. There is no private element and no dual purpose. The deduction satisfies the wholly and exclusively test without difficulty and reduces the firm's taxable profit in the period the expense is incurred. For LLPs (which are excluded from the cash basis and use the accruals basis), this reduces the trading profit allocated to members and so reduces each member's income tax and Class 4 NIC liability in proportion to their profit share.
VAT on the provider fee (standard-rated at 20%)
An outsourced cashiering provider supplies a professional management service. Management and bookkeeping services do not appear in any of the 16 exempt-supply groups in VATA 1994 Schedule 9 (verified at legislation.gov.uk on 9 July 2026). The supply is standard-rated at 20% VAT by default.
Input VAT recovery. If the firm is VAT-registered (the registration threshold is £90,000 from 1 April 2024) and makes predominantly taxable legal supplies, it recovers the input VAT on the provider's fee through its VAT return. The cashiering fee is an overhead attributable to the firm's taxable activities. For a typical law firm whose income is predominantly standard-rated legal services, the 20% VAT on the cashiering fee will be fully recoverable, making it cost-neutral.
A firm that is not VAT-registered bears the 20% VAT as an irrecoverable cost, increasing the effective provider fee. This is a relevant variable when applying the full-cost template in the previous section.
Partial exemption note. For a firm with non-incidental exempt income (HP §6.C), input VAT on overheads may be partially restricted. For a typical law firm with predominantly standard-rated legal income, the cashiering fee VAT will be fully recoverable. If there is any doubt, apply the firm's partial-exemption method to the cashiering fee as an overhead.
Treatment in the firm's accounts
The cashiering fee is a practice overhead and sits in the profit and loss account, not on the balance sheet. It does not attract capital allowances because it is not expenditure on plant or machinery. It is an expense of the period in which it is incurred.
When outsourcing may not be the right model
Not every firm should outsource its cashiering function. Factors that weigh against it:
High-volume, time-critical client account activity. A conveyancing-heavy practice with multiple completions per day and tight payment deadlines may find that the latency of working with an external provider creates operational risk. Payment windows on completion days are short; a provider that cannot respond immediately to an urgent payment instruction creates a material problem.
Recent regulatory history. A firm with a recent SRA investigation or client account breach may find that close COFA oversight of an in-house cashier provides a stronger control environment than an outsourced model, at least until the firm's regulatory position is fully restored. The COFA needs direct, real-time visibility into the client account during recovery periods.
Small-balance practices where the compliance driver is limited. For a sole practitioner or very small firm with minimal client account activity, the Rule 12.2 exemption (average balance not exceeding £10,000 and maximum not exceeding £250,000) may already apply. If the report trigger is removed, the compliance overhead that an outsourced cashier is primarily hired to manage is much reduced. In that case, the TPMA model may remove the compliance layer entirely rather than just managing it. See our guide to third-party managed accounts for law firms and our discussion of the no-client-account model for firms exploring the alternative.
