Client hasn’t paid: should you pause consultancy work?

Check why payment is late and whether the invoice is disputed

Start with a factual check rather than a firmer version of your last reminder. Review the agreed fee, payment deadline, scope changes and any completion or sign-off records. The solicitor guidance in source 6 recommends establishing what was agreed and why payment is being withheld before escalating.

Contact both your project sponsor and the person handling payment. Ask whether the invoice has been received, whether anything is blocking approval and when payment is expected. If the answer is “it is with finance”, ask who can confirm the next step. Keep the language neutral: you are trying to identify a blockage, not assign blame.

If the client challenges your work, ask them to identify the deliverable, agreed requirement and amount they dispute. Keep that discussion distinct from a routine payment chase. Ask whether any undisputed amount can be paid while you address the concern, without suggesting that either side has already accepted the other’s position.

• Check the invoice reference, recipient, purchase order details and payment instructions.
• Match the invoice to the agreed milestone or billing arrangement.
• Ask for any disputed items in writing, with the reasons for withholding payment.
• Record the named payment contact, promised action and next follow-up.

Calculate how much more unpaid work you can afford

Do not make the decision from the overdue invoice alone. Prepare a working view of your exposure: unpaid invoices, work already delivered but not yet billed, and costs you have committed to the assignment. Keep billable value separate from actual cash outgoings so you do not confuse lost earning capacity with money leaving your account.

Then look ahead to your next sensible review point. What would continuing require: analysis, stakeholder interviews, a workshop, subcontractor time or travel? Estimate the additional unpaid work and unavoidable spending if payment still has not arrived. Avoid counting the same work in both an invoice balance and unbilled time.

Use that picture to set an internal limit on what you are willing to risk, subject to your contractual obligations. Consider your other client commitments and essential business payments too. If you cannot comfortably absorb the next stage, begin the contract review and delivery conversation now rather than after completing it.

• Already exposed: overdue invoices and unbilled work, shown separately.
• Additional exposure: work and spending needed before the next review.
• Cash pressure: essential outgoings due while payment remains uncertain.
• Decision point: the next commitment you need to discuss before proceeding.

Review suspension clauses, notice requirements and delivery obligations

Do not treat an overdue invoice as automatic permission to stop work. Gather the contract, applicable terms, proposal, purchase order, agreed variations and relevant correspondence. Source 6 highlights these kinds of documents when establishing the payment agreement. For the delivery decision, use them to prepare questions about what you can change and how.

Look for wording about suspension for non-payment, any opportunity to remedy the problem, how notices must be sent and which obligations continue during a pause. Also check the milestone and dependency wording: what happens to the delivery timetable if work is interrupted? Do not assume that an ordinary reminder email satisfies a formal notice requirement.

If there is no clear clause, the documents conflict or the client disputes your performance, ask a solicitor to review the position before withholding contracted work. Ask specifically about suspension, termination and the risks of each rather than treating them as interchangeable. Your financial limit is a reason to seek a resolution; it is not a substitute for checking your obligations.

Choose between continuing, agreeing reduced delivery or pausing

Choose the option that fits both the payment evidence and your contractual position. A specific explanation, named approver and confirmed payment date give you more to assess than repeated assurances that payment is coming. If you continue, set a review point and decide what evidence you need before committing further time.

Reduced delivery is worth discussing when the client still needs progress but you cannot comfortably fund the full programme. You might propose completing an agreed handover while rescheduling a workshop, for example. Seek written agreement on precisely what changes; do not quietly reduce the service while leaving the original expectations untouched.

If a pause is the appropriate route, confirm the contractual basis or obtain agreement before implementing it. Identify affected deliverables, outstanding decisions and any responsibilities that remain. Keep payment recovery and future delivery as related but separate conversations: a pause should not leave either side guessing about the unpaid invoice or the project.

Write a payment-and-delivery message without making threats

Keep your message factual and easy to act on. State the invoice reference, outstanding amount and agreed due date, then explain the delivery decision that needs resolving. Direct engagement and personalised reminders are among the approaches described by the Small Business Commissioner in source 3.

The example below is a request to agree next steps, not a formal suspension notice. Replace the placeholders with your records and remove anything that does not fit. If you intend to exercise a contractual right, have the required notice checked rather than relying on a general email template.

“I’m following up invoice [reference] for [amount], due on [agreed date]. Please confirm whether anything is blocking payment or whether you dispute any part of the invoice. Our next planned activity is [activity]. I would like to agree how we handle that stage while payment remains outstanding. My proposal is [specific delivery change], subject to written agreement. Please confirm the payment position and your response by [response date]. If we agree a pause, let’s also record the payment and scheduling conditions for restarting.”

Avoid threats you have not assessed or actions you do not intend to take. Follow any call with a written summary, and distinguish what has been agreed from what you have merely proposed. A response deadline in this message should not be presented as overriding any contractual notice process.

Agree restart conditions and know when to seek legal advice

Before an agreed pause begins, write down what would make restarting workable. Specify the payment position you need, how any unresolved dispute will be handled and which deliverables remain. If you want advance payment or a different billing arrangement for future stages, propose and agree it rather than presenting it as an existing term.

Confirm the revised schedule separately. Avoid promising that payment will automatically restore the original delivery dates: check your availability, the client’s readiness and any subcontractor commitments first. Record what happens to postponed meetings, outstanding approvals and inputs needed from the client.

Seek legal advice before acting where suspension rights are unclear, the client alleges breach, a critical deadline is approaching or you are considering formal recovery or termination. Bring the agreement, invoice history, delivery evidence and correspondence. For current recovery procedures, check GOV.UK or a professional adviser rather than assuming that a payment chase, suspension notice and formal legal demand serve the same purpose.

• Payment: what needs to be received or agreed before restarting?
• Scope: what remains, and what has changed?
• Readiness: which client inputs and approvals are still needed?
• Timing: what revised dates can both sides commit to?
• Confirmation: who will record and approve the restart arrangement?

How Invoices and payments helps

HappyNoodle’s Invoices and payments workflow lets you create invoices from the work, make payment simple and keep polite reminders connected to the right client. Use that workflow for the payment follow-up while you separately review your contract and discuss delivery. Keep reminders focused on the invoice rather than treating them as suspension notices. If you agree a revised delivery arrangement, check that subsequent invoicing reflects the work and payment terms you have actually agreed.
