Start With a Small Yes: The 20-Minute Deposit Policy That Protects Your Week

Most solo service businesses have a quiet cash-flow leak: the gap between a client saying yes and the invoice actually being paid. You book the work, block out the diary, start the deep dive, and only then discover the client has gone quiet. A deposit does not make you cynical. It makes your calendar honest.

As of November 2026, plenty of UK sole traders are still quoting, booking and starting work before any money changes hands. That is understandable. You want to be helpful, you do not want to scare people off, and asking for money early can feel awkward. But a small, clear deposit policy is one of the quickest ways to protect your week, reduce no-shows and stop unpaid prep eating into your margin.

Why a deposit is a diary tool, not a distrust tool

A deposit is not a penalty. It is a booking fee that becomes part of the final invoice. For consultants, designers, bookkeepers, cleaners, therapists, tradespeople and anyone else selling time or expertise, it does two useful jobs at once.

First, it filters. Someone who is serious about the work will usually pay a modest deposit without much drama. Someone who is only half-committed often reveals that before you have cleared your diary for them.

Second, it covers the small costs of saying yes. The admin, the preparation, the materials, the slot you could have given to another client. You do not need a heavy legal document to make that point. You need a simple rule and a calm explanation.

The 20-minute sprint

Set a timer and do this in one sitting. Do not turn it into a branding project.

1. Decide your deposit amount. Keep it simple: a percentage, a fixed booking fee, or the first session paid upfront. One rule is better than five.
2. Decide when it is due. For example, within three working days of booking confirmation.
3. Decide what happens if it is not paid. The slot is not held. That is the whole policy.
4. Write a one-page note you can attach to enquiries and invoices.
5. Practise one short script for the first client conversation.

That is it. You are not building a finance department. You are closing a gap.

A simple rule that fits most solo service work

For project work, a deposit of 20% to 30% is common. For lower-value or recurring services, a fixed booking fee or first payment upfront can be easier to explain. A cleaner might ask for the first clean to be paid when booked. A consultant might ask for 25% before the kick-off call. A therapist might take payment for the first session in advance.

The amount matters less than the consistency. If every client gets the same clear rule, it stops feeling personal. It becomes part of how you work, like sending a calendar invite or confirming a start time.

What to put in writing

Your deposit policy does not need to be long. One page is plenty. It should cover the amount, the due date, how to pay, what the deposit covers, and what happens if plans change. Keep the language plain. If a client has to read it twice to understand it, simplify it.

A useful one-page template looks like this:

Booking Deposit Policy - [Business Name]

Effective from: [date]

Applies to: [service type or projects over £X]

Deposit: [25%] of the quoted fee, or [£X], whichever is greater

Due: within [3] working days of booking confirmation

Payment: [bank transfer / payment link]

What it covers: holds your date, covers initial admin and preparation, and is deducted from the final invoice

Rescheduling: [48 hours] notice and the deposit moves once

Cancellation: [your terms here]

Refund: [your terms here]

Questions: [email address]

This is not legal advice, and you should check your terms if you are dealing with larger projects or unusual circumstances. But for most micro-businesses, a plain one-pager is a huge improvement on an unspoken expectation.

The first client conversation

Do not save the deposit conversation for the invoice. Mention it before you book the time. A short script keeps you calm and stops you over-explaining.

'Before we book the time, I ask for a 25% deposit. It holds your slot and comes off the final invoice. I will send a one-page note with the dates and payment details. Does that work for you?'

If they hesitate, do not rush to fill the silence with a discount. Try: 'I understand. I keep the deposit small and it is credited against the final invoice, so it is not an extra cost. It just protects the time I set aside for you.'

If they still push back, that is useful information. You can decide whether to make an exception, but do it deliberately, not because you panicked.

The awkward bit: saying it without sounding suspicious

Tone does most of the work here. Avoid apologising for having a policy. Avoid long speeches about bad clients from the past. Keep it neutral and matter-of-fact.

Useful phrases include: 'This is how I hold project dates', 'It comes off the final invoice', and 'It keeps both our diaries protected.' Those phrases are clear without suggesting you expect the client to mess you about.

For very small services, you can make it even lighter: 'I take the first payment when we book, then it is session by session after that.' Simple, friendly and done.

After the sprint: three small habits

First, add the deposit line to your quote template so you do not have to remember it every time. Second, do not start work until the deposit has landed. A booking is not a booking if the slot is still floating. Third, review it monthly. If you are getting lots of no-shows or lots of unpaid prep, your policy is not strict enough. If you are losing good clients, it may be too heavy.

The aim is not to become the most rigid business on your street. The aim is to start with a small yes, protect your cash flow, and make your diary mean something. Twenty minutes now can save you a lot of quiet chasing later.
