FACT CHECKED
Quick Summary
Cash-intensive trading can attract extra questions because cash is harder to evidence end-to-end than card or invoice-paid receipts.
Where cash deposits rise, change suddenly, or don’t match the stated business model, Tide may ask for clarification and supporting documents as part of routine security reviews, and in some cases apply temporary limits while information is assessed.
The operational risk is usually disruption: delays to outbound payments, deposit or transfer limits, and time spent producing “proof of trade” that connects cash deposits to real sales and normal business activity.
This article is educational and not financial advice.
What “cash-intensive” means in a Tide context
“Cash-intensive” does not require a business to be cash-only. In practice it often means one or more of the following patterns:
Regular cash deposits that form a meaningful portion of turnover. Tide supports cash deposits via the Post Office and PayPoint, with published deposit limits and fees. See Tide’s guide on depositing cash and cheques into your Tide account and the step-by-step explainer on how to deposit cash into a Tide account.
Cash deposits that change shape (sudden increases, new frequency, different locations).
Cash deposits that do not match the stated model (for example, a business described as “online-only” begins depositing significant physical cash).
For the broader, bank-wide mechanism (not Tide-specific), see our provider-agnostic guide on cash-intensive businesses and why banks ask more questions.
Why cash can trigger extra questions
Cash is a recognised financial crime vulnerability
Cash has weaker built-in audit trails than bank-to-bank payments. That doesn’t imply wrongdoing; it explains why controls are tighter.
The FCA has highlighted vulnerabilities around cash deposits – particularly through shared deposit channels – and published expectations on mitigating cash deposit money laundering risk in its update on cash-based money laundering.
Ongoing monitoring is expected across the relationship
Extra questions are often part of “ongoing monitoring”: confirming activity remains consistent with what a provider knows about a business.
HMRC’s Economic Crime Supervision guidance summarises ongoing monitoring expectations and how transaction patterns and customer information updates fit into that control framework in ECSH33375 – Ongoing monitoring.
Industry guidance also frames monitoring as risk-based scrutiny of transactions over time; see JMLSG Part I Chapter 5.7 Monitoring customer activity.
Cash deposits can look like “business model drift”
Even where cash trading is normal, reviews are commonly triggered when the pattern doesn’t fit the stored profile. If cash deposit behaviour changes, it can overlap with a broader “profile mismatch” dynamic (what the business said it does versus what activity now suggests). That mechanism is explored from a Tide angle in Tide business model mismatch flags.
Tide-specific realities that matter for cash-heavy businesses
Cash deposits are supported, but with defined parameters
Tide’s help content sets out how cash deposits work, including stated deposit limits and fee structures by channel and plan (Post Office versus PayPoint) in depositing cash and cheques into your Tide account. Separately, the Post Office describes availability of Tide services in branch (including cash deposit) on its Tide services page.
Where cash deposits are a frequent operational need, the practical point is that deposit controls, limits, fees, and processing cut-offs can create “friction” during busy periods – and those same deposits can also become a focal point during monitoring reviews.
“Routine security reviews” can include business-model and activity checks
Tide explains that it conducts routine reviews that consider account activity, how the business makes money, the industries it operates in, and whether details have changed, and that accounts may be paused during review in some cases on its routine security reviews page.
Cash-heavy activity is one of the patterns that can prompt clarification where it represents a change or does not align with the existing profile.
A cash-linked review can range from light-touch clarification to temporary restrictions. The key difference is whether a provider is simply updating the business profile or applying a control that affects payments while information is assessed.
For Tide-specific process framing and typical outcomes, see Tide account under review stages. If restrictions are applied, “what still works” can vary by restriction type; we cover common patterns in Tide account locked or frozen: what usually still works. The difference between restriction and closure (and why it matters operationally) is set out in Tide restricted vs closed.
Summary Table
| Scenario | Outcome | Practical impact |
|---|---|---|
| Regular cash deposits begin for the first time | Activity clarification requested | Time spent evidencing “why cash” and linking to trading |
| Cash deposits increase sharply (frequency or value) | Enhanced review of trade pattern | Possible temporary limits while information is assessed |
| Cash deposits don’t match stated business model | Profile mismatch review | More detailed evidence requests; review may take longer |
| Deposits made across multiple locations or by multiple staff | Additional questions about process and controls | Requests for operational explanation (till process, reconciliation, roles) |
| Large cash deposits followed by rapid outbound transfers | Source-of-funds style scrutiny | Outbound payment delays; additional documentation requests |
| Repeated deposits just under a limit | Monitoring flag for pattern | More questions about deposit rationale and record-keeping |
| Cash-heavy business with limited invoicing trail | Proof-of-trade focus | Requests for POS reports, daily takings summaries, supplier invoices |
| Cash activity coincides with ownership/role changes | Reverification overlap | ID/role confirmation plus trading evidence requested |
What evidence is commonly requested for cash-heavy activity
Cash reviews tend to be about linking deposits to real sales and showing that the cash handling process makes sense for the business type. Requests commonly cluster into:
Trading proof: sales records, receipts, booking logs, job sheets, delivery notes, or contracts where relevant.
Till / POS reporting: Z-reads, daily takings summaries, refund logs, and reconciliation reports.
Supplier chain evidence: supplier invoices, stock purchase records, and payments that correspond to cash-driven sales volumes.
Cash handling process: who collects, counts, and deposits cash; how discrepancies are recorded; and how the business reconciles cash to sales.
Tide-specific document patterns and why requests may repeat across reviews are covered in Tide compliance review documents. For the broader “evidence pack” concept many UK providers use, see bank review evidence packs.
Scenario table
| Scenario-level signal | Process-level response | Outcome-level effect |
|---|---|---|
| Cash deposits rise relative to historical pattern | Request for explanation + supporting evidence | Temporary account limits may be applied while reviewed |
| Cash deposits don’t align with stated industry/model | Profile review (business model reassessment) | Deeper evidence requests; longer review cycles possible |
| Cash deposits are fragmented across locations/staff | Operational controls questions | Requests for reconciliation records and deposit process description |
| Deposit-to-transfer “flow-through” behaviour | Source-of-funds style review | Outbound payment delays and beneficiary scrutiny |
| Repeated “edge” deposit patterns (near limits) | Monitoring escalation | Additional clarification requests; activity may be constrained |
Tide Business Bank Account
Tide is a digital business account offering with plan-based pricing and feature differences. For a neutral overview of Tide’s account structure, typical fees, and trade-offs, see our Tide business bank account review.
For cash-heavy businesses, the practical point is that operational tooling (deposit channels, deposit limits, and fees) and compliance processes (reviews and evidence requests) interact.
Where cash deposits form a consistent part of turnover, the “paper trail” and reconciliation discipline often becomes the deciding factor in how smoothly reviews run.
Frequently Asked Questions
Not automatically. Tide supports cash deposits via the Post Office and PayPoint, and publishes how deposits work, including deposit limits and fees, in its guide to depositing cash and cheques into your Tide account. The existence of deposits alone is not the same as a restriction or closure outcome.
Where reviews tend to appear is when deposit behaviour changes, becomes difficult to reconcile to the stated business model, or stacks with other signals (such as unusual outbound transfers). Tide describes that its routine reviews consider account activity and how the business makes money on its routine security reviews page.
Cash is harder to evidence end-to-end. Card receipts typically link to a processor trail, and invoiced payments can link to counterparties and contracts. Cash deposits rely more heavily on internal records (till reports, reconciliation, supplier invoices) to demonstrate that deposits reflect genuine sales.
Regulators and supervisors also treat cash deposits as a known vulnerability. The FCA has published expectations on mitigating risk in its page on cash-based money laundering, and monitoring guidance commonly expects scrutiny of transactions over time, as outlined in JMLSG Chapter 5.7 Monitoring customer activity.
Cash reviews usually focus on linking deposits to real-world trade and showing that the cash handling process is coherent for the business type. That often means POS/till reports, daily takings summaries, reconciliation logs, refund logs, and evidence of stock purchases or supplier payments that match sales volumes.
If a business has mixed income (some cash, some transfer, some card), checks may also look for consistency between channels – for example, whether cash deposits align with stated premises, opening hours, booking records, or job sheets. For Tide-specific patterns of what tends to be requested, see Tide compliance review documents.
They can be, depending on cut-off timing and processing windows. Tide’s own deposit guidance describes typical processing expectations and differences between Post Office and PayPoint in its cash deposit help content.
Separately, the Post Office explains the Tide services it supports in branch on its Tide services page. Even where deposits are supported, operational delays can still occur (for example, end-of-day timing or non-business days), which can matter more for cash-heavy trading where deposits fund near-term outbound payments.
It’s often about the shape of behaviour rather than a single deposit. Examples include sudden increases in deposit size or frequency, deposits split across multiple locations or staff in ways that don’t match the business footprint, or deposits that are quickly transferred out in a way that resembles pass-through activity.
Patterns that sit near published limits can also attract questions, because monitoring systems look for repeated “edge” behaviours. Importantly, a pattern being queried is not the same as a conclusion; it is commonly a prompt to confirm the economic rationale and record-keeping that explains the behaviour.
Restrictions vary by case type. Some reviews remain “information-only”, while others involve temporary limits on parts of account functionality while information is assessed, which Tide references as a possibility on its routine security reviews page.
Where restrictions are applied, the practical impact is usually felt on outbound activity (transfers, new beneficiaries, or certain payment types). For Tide-specific staging and typical outcomes, see Tide account under review stages, and for function-level expectations, see what usually still works.
They overlap, but they are not identical.
- “Cash intensity” is often a business-model and record-keeping question: how cash is generated, counted, and deposited, and whether the pattern is consistent with the business profile.
- “Source of funds” questions focus more directly on where specific money came from and whether it can be evidenced as legitimate.
In practice, a cash-heavy pattern can trigger source-of-funds style questions when deposits are large, sudden, or paired with rapid outbound transfers. Tide-specific framing of these questions is covered in Tide source of funds checks.
There are practical and legal constraints around explaining detailed monitoring triggers. Disclosing precise indicators can reduce the effectiveness of controls, and some restrictions on disclosure can apply in financial crime contexts.
That is why communications can feel generic (“unusual activity” or “additional information required”) even when the underlying review is specific. We cover these constraints and the “tipping off” theme in why banks can’t explain restrictions.
It can, but closure is typically an outcome of a broader decision: whether the account remains eligible for the provider’s service and risk appetite after review, and whether information requested can be provided in a way that resolves the concern.
Cash intensity on its own is not inherently disqualifying, but unresolved inconsistencies can lead to stronger actions.
Where a closure decision is made, the operational difference between being restricted and being closed matters (timelines, functionality, and next steps). That distinction is covered in Tide restricted vs closed.
Yes. Ongoing monitoring is not limited to new businesses. Changes in activity, ownership, sector exposure, or transaction patterns can lead to periodic rechecks. HMRC describes ongoing monitoring as an expected control across the relationship in ECSH33375 – Ongoing monitoring, and industry guidance frames monitoring as risk-based scrutiny over time in JMLSG Chapter 5.7.
This is also why established SMEs can face periodic KYC refreshes even when trading is stable. For that angle, see periodic KYC refreshes for established SMEs.
Cash intensity is not a judgement about a business’s legitimacy; it is a documentation problem disguised as a payments problem.
Because cash lacks a native counterparty trail, the “truth” of the activity has to be reconstructed from internal records:
- POS reports
- Reconciliations
- Supplier invoices
- Coherent operational narratives about how cash is handled
On app-based business accounts, cash deposits also sit at the intersection of product design and compliance controls. When cash deposits become a material input to liquidity (funding payroll, suppliers, tax), any review-driven pause can create outsized disruption – which is why the operational “paper trail” often determines whether a review remains a short clarification or turns into a longer restriction process.
