Quotes and invoices for a one-van business: getting paid at the door

A debt in a one-van business is not a receivable, it is a day you already worked and have not been paid for. There is no credit control department, no collections process and no appetite for chasing somebody you may see again at the supermarket. The money either arrives at the door or it becomes a slow, awkward problem.

Which is why the interesting question is not how to send a quote faster. It is what the quote has to establish before you arrive, so that the moment the job finishes the payment is the obvious next step rather than a negotiation.

Unpaid work costs more than you think

The headline cost of an unpaid job is the invoice. The real cost is larger.

The parts are already bought. You funded them, and for a bad debt you never get that back.

The day is spent. Unlike stock, an hour cannot be resold later.

Chasing it costs hours you do not have, in the evening, which is when everything else administrative also happens.

It affects what you take on next. A business waiting on three invoices is a business that cannot buy parts for the fourth job.

So the objective is not faster invoicing. It is fewer invoices outstanding at all, which is a different design and mostly happens before the work starts.

What a quote must state before you arrive

Six things, all of which prevent a doorstep conversation.

What is included and what is not. The commonest dispute in every trade.

Whether there is a call-out or minimum charge, and whether it comes off the work.

Your VAT position. Whether the figure includes VAT, or whether you are not registered and there is none to add. A customer assuming the first when you meant the second is a twenty per cent argument.

What happens if it turns out to be something else. The condition on which the number changes, stated plainly.

When payment is due and by what method.

How long the price holds. Particularly where parts prices move.

Put those in the message that carries the price, not in terms nobody reads. Six lines, once, written and reused.

Quote, estimate, and the price that moved

A quote is a fixed price for defined work. An estimate is a projection that can move, and it only works as one if you said it was an estimate and said what would change it.

Trades use the words loosely and customers do not. A figure sent without qualification reads as a quote, whatever you intended, and the conversation when the bill is higher starts from that assumption.

Where you are genuinely unsure, price the diagnosis rather than the repair. "£X to come and find out what it is, and I will price the fix before doing it" is honest, chargeable, and removes the whole category of argument. It is also a better filter than a rough figure, because the customers who will not pay to have it looked at were rarely going to approve the repair.

Payment at completion is the whole game

The moment the job is finished and the customer is standing there satisfied is the easiest moment to be paid that will ever occur. Every hour after it the payment gets harder, and every day after that harder again.

Three things make it happen.

Say at booking that payment is on completion. Nobody objects to a term they were told in advance; they object to one sprung on them.

Have more than one way to take it. Card on the doorstep, a payment link to their phone, bank transfer while you are there. The customer who cannot pay the way you offer becomes a customer who pays next week.

Send the invoice before you drive away. An invoice issued from the doorstep gets paid at a completely different rate from one sent at nine that evening.

For anything substantial, a deposit covering the parts is reasonable and normal. It is not about trust, it is about not funding somebody else's boiler out of your own working capital.

Building it with CodeWords

CodeWords connects to more than 3,000 integrations, and the connection is made once and reused.

1. Open CodeWords and start a new automation.
2. Describe what should happen in plain language to Cody, the automation builder: what the quote message contains, what marks a job complete, when the invoice goes and with which payment link, and what the reminders are.
3. Authorize the connections to your payment provider, your accounting or invoicing tool, and your WhatsApp Business Platform account.
4. Describe the exceptions: a customer disputing something, a job part-finished, an account customer on terms, anyone you have agreed different arrangements with.
5. Run it alongside your current process for a fortnight and compare how long invoices actually take to clear.

You describe the outcome; Cody builds it, connects it, and deploys it. The free plan covers light use, with Pro at $39 per month and Business at $100 per month as usage grows; details are on the pricing page.

Never take card details in a chat

Worth being blunt about, because it still happens in every trade.

A card number sent in a message sits on two phones, in two backups, possibly on a shared work device. Your payment provider's terms almost certainly forbid handling card details that way, and taking a payment from a number typed into a thread usually breaks them.

The reason that matters most, though, is what it teaches. A customer who has sent card details to a tradesperson in a chat once will do it again for the next person who asks in a friendly tone, and the next person may be somebody impersonating you. Sending a payment link costs nothing, takes the same thirty seconds, and keeps the numbers out of the conversation entirely.

The same applies to bank details in reverse. Payment redirection fraud, where somebody intercepts or spoofs the message carrying the account number, is common in the trades. Where a customer is paying by transfer for anything significant, confirming the account verbally is a two-minute habit that prevents a very bad week.

Cancellation rights, which catch most trades out

Where a contract is agreed at the customer's home or over the phone, it is an off-premises or distance contract and the consumer has a 14-day cancellation right.

For work to start inside that period the customer has to make an express request, which for an off-premises contract must be in writing, and they have to be told they lose the right to cancel once the service is fully performed (Business Companion).

Most sole traders have never done this and are carrying a risk they do not know about. A messaging thread is actually a convenient place to handle it properly: the required information goes out with the quote, and the customer's request to proceed arrives in writing, timestamped, without anybody having to produce a paper form on a doorstep.

The invoice itself

Plain, and it needs less than people think, but the bits it does need matter.

Your business name and contact details. The customer and the address the work was done at. The date. What was done, in words they recognise from the quote. Parts and labour split if you quoted it that way. The total, with VAT stated if you are registered, and your VAT number if so. How to pay and by when.

Two additions worth making. A line covering any guarantee on the work, since it is the question you get asked most after the fact. And, where relevant, what remains outstanding, so a part-finished job does not read as a completed one.

Keep the record yourself rather than relying on the thread. Message histories live on handsets, and a business needs its invoices somewhere that survives a phone going in a toilet.

Chasing, without the awkwardness

The reason unpaid invoices go unchased in small trade businesses is not forgetfulness. It is that asking feels rude.

Automation removes the decision, which is the actual help. A reminder at seven days, another at fourteen, both short and neutral, going to everybody on the same schedule regardless of how well you know them. Nobody is being singled out, because nobody is being chosen.

After that it stops being automatic. A genuinely overdue invoice is a decision: a phone call, a final notice, or writing it off as the cost of learning something about that customer. Where a customer is disputing rather than avoiding, the reminders should stop entirely the moment they reply, because a sequence running alongside a complaint makes it considerably worse.

Making it survive

Say the payment terms at booking, every time, in writing.

Issue the invoice before leaving, not in the evening.

Use payment links, never card details in a thread.

Stop reminders on any reply and route it to you.

Keep invoices outside the messaging app, in something that survives a lost phone.

Limits worth knowing about

Faster invoicing does not fix underpricing. A promptly paid unprofitable job is still unprofitable.

Some customers will not pay, and small-value debt recovery is rarely worth the time.

Payment providers charge, and card on the doorstep costs more than a transfer.

Account customers work differently, and agreed terms are a commercial relationship rather than a failure of process.

No automation makes an awkward conversation unnecessary, it only reduces how often you have to have one.

What to build first

The six-line terms block that goes out with every price: what is included, call-out or minimum charge, VAT position, what changes the number, when payment is due, and how long the price holds. Written once, sent every time, before anybody sees the van.

Two habits make the difference. Invoice from the doorstep while the customer is standing in front of the finished work, because that is the easiest money you will ever collect. And send a payment link rather than ever taking card details in a chat, since the habit you are teaching a customer is the one an impersonator will use on them next.

Frequently asked questions

Why do unpaid invoices hurt a small trade business so much?

The parts are already funded, the day cannot be resold, chasing happens in the evening, and outstanding money limits what you can take on next. The aim is fewer invoices outstanding rather than faster invoicing.

What should a quote state before the visit?

What is included and excluded, any call-out or minimum charge, your VAT position, what would change the number, when payment is due, and how long the price holds.

What is the difference between a quote and an estimate?

A quote is a fixed price for defined work; an estimate can move and only behaves that way if you said so and said why. Where you are genuinely unsure, price the diagnosis instead.

When should payment be taken?

On completion, while the customer is standing in front of the finished work. Say so at booking, offer more than one method, and issue the invoice before driving away.

Can I take card details over a messaging app?

No. It almost certainly breaches your payment provider's terms, and more importantly it teaches customers to send card numbers to anybody who asks in a friendly tone. Send a payment link instead.

What about bank transfer details?

Send them, but confirm the account verbally for anything significant. Payment redirection fraud is common in the trades and a two-minute check prevents it.

Do deposits make sense?

For anything with substantial parts, yes. It stops you funding somebody else's materials out of your own working capital, and customers generally expect it.

What are the cancellation rules for work agreed at a customer's home?

There is a 14-day cancellation right. To start inside it the customer must expressly request it, in writing for an off-premises contract, having been told they lose the right to cancel once the work is fully performed.

What has to be on the invoice?

Your details, the customer and the site address, the date, what was done in the same words as the quote, parts and labour if quoted that way, the total with VAT and your VAT number if registered, and how and when to pay.

How should overdue invoices be chased?

On a fixed schedule that applies to everybody, which removes the awkwardness by removing the choice. Stop automatically on any reply, and treat a genuinely overdue invoice as a decision rather than a longer sequence.
