There is no universal “right” Meta advertising budget

A service business should not choose its advertising budget simply because another company spends the same amount.

The appropriate figure depends on:

• What a new customer is worth

• The gross profit available from each sale

• How often a genuine enquiry becomes a customer

• How quickly enquiries are followed up

• How much testing the campaign needs

• How much new work the business can realistically handle

A £750 monthly budget may be sensible for one business and completely unsuitable for another.

The purpose of setting a budget is not to spend as little as possible. It is to give the campaign enough room to produce useful evidence without risking an amount the business cannot afford to lose.

Start with the value of a customer

Before deciding what to spend, calculate the approximate gross profit generated by a typical new customer.

Gross profit is more useful than revenue because advertising has to be paid for after the direct cost of delivering the service has been considered.

For example, imagine a business sells a service for £2,000 and spends £1,200 delivering it. The approximate gross profit is therefore £800.

The business must then decide how much of that £800 it could reasonably invest to acquire the customer while still leaving an acceptable return.

It might decide that paying up to £200 to acquire a new customer would be commercially worthwhile.

That £200 becomes the business’s provisional maximum customer-acquisition cost. It is a planning figure rather than a guarantee.

Work backwards from your sales conversion rate

Advertising normally generates enquiries rather than completed customers. The business therefore needs to understand what happens after an enquiry arrives.

Suppose one in five qualified enquiries becomes a customer.

If the business can afford to spend £200 acquiring a customer, its provisional maximum cost per qualified enquiry would be:

£200 divided by five enquiries = £40 per qualified enquiry

This does not mean Meta will necessarily produce qualified enquiries for £40. It simply gives the business a commercial benchmark against which results can be assessed.

The calculation also shows why lead quality matters.

Ten enquiries costing £20 each may look better than five enquiries costing £35 each. But if none of the cheaper enquiries is genuine and two of the more expensive enquiries become customers, the apparently expensive campaign has produced the stronger commercial result.

Cheap leads are not necessarily good leads

Meta can sometimes generate a large volume of form submissions at a relatively low cost.

That figure can be misleading when the people submitting the form:

• Do not understand the price

• Live outside the service area

• Cannot be contacted

• Are looking for something the business does not provide

• Have no realistic intention of buying

• Are not ready to proceed within a useful timeframe

A campaign should therefore be judged on the journey from initial enquiry to customer, not just the number shown inside Meta Ads Manager.

Useful reporting may include:

• Total enquiries

• Valid contact details

• Qualified opportunities

• Appointments or consultations

• Quotes or proposals issued

• Customers acquired

• Revenue and gross profit generated

Not every business will track all of these perfectly at the beginning. However, the closer the reporting gets to real commercial outcomes, the more useful the advertising decisions become.

Why very small budgets can be difficult to assess

A small budget is not automatically wasted, but it may take longer to produce enough information to support a confident decision.

Meta campaigns usually need to test several variables, including:

• The offer

• The advertising message

• The creative

• The audience

• The geographic area

• The form or conversion route

• The qualification questions

When only a small number of people see or respond to the advertising, it becomes difficult to tell whether a weak result reflects the campaign itself or ordinary short-term variation.

For example, receiving one poor enquiry does not prove that an entire campaign is unsuitable. Equally, receiving one unusually valuable customer does not prove that the result will repeat consistently.

A defined testing period helps reduce the risk of making decisions from isolated events.

Why The Enquiry Works uses a £750 monthly minimum

For campaigns managed by The Enquiry Works, the minimum Meta advertising budget is £750 per month, paid directly by the client to Meta.

This is not presented as a universal rule for every advertiser. It is the minimum budget at which I believe a managed campaign can usually be assessed with a reasonable degree of structure over the initial testing period.

The budget still has to make commercial sense for the individual business.

A company should not spend £750 simply because it meets the service minimum. The customer value, margins, sales process and available capacity must support the decision.

Where the likely economics do not appear realistic, the appropriate recommendation may be to improve the offer, pricing, follow-up process or tracking before advertising begins.

Consider the full initial commitment

Advertising spend is only one part of the investment.

A business should consider:

• Campaign setup costs

• Monthly management fees

• Meta advertising spend

• Time spent responding to enquiries

• Any software or landing-page requirements

• The operational cost of serving additional customers

With The Enquiry Works, the initial three-month commitment consists of £2,145 in professional fees, plus at least £2,250 paid directly to Meta.

This provides a defined period in which the offer, targeting, messaging and lead quality can be tested and reviewed.

It does not guarantee enquiries, customers, revenue or profitability. It also does not mean continued spending should be recommended when the evidence does not support it.

Make sure the business can respond properly

Increasing the budget will not solve a weak follow-up process.

Before launching, decide:

• Who will receive the enquiries

• How quickly they will respond

• How many times they will attempt contact

• What questions they will ask

• How outcomes will be recorded

• How many additional customers the business can accept

A qualified opportunity can still be lost when it sits unanswered for several days.

The advertising and the sales response should therefore be considered as parts of the same commercial process.

A practical budgeting example

Consider a kitchen-installation business with the following approximate figures:

• Average sale: £12,000

• Approximate gross profit: £3,000

• Acceptable acquisition cost: £600

• One customer gained from every six qualified enquiries

Its provisional maximum cost per qualified enquiry would be:

£600 divided by six = £100

At a £750 monthly advertising budget, the campaign would not need dozens of customers to be commercially meaningful. However, it would still need enough genuine enquiries to determine whether the £100 planning threshold was realistic.

Now consider a business making only £300 gross profit per customer and willing to spend £60 to acquire one. If only one in ten enquiries becomes a customer, the provisional maximum cost per qualified enquiry would be just £6.

That may leave too little room for a managed Meta campaign, particularly in a competitive market.

The second business may need to improve its margin, increase customer value, strengthen its conversion rate or choose another acquisition method.

Review the evidence rather than defending the original plan

An advertising budget should not become a commitment to keep spending regardless of the result.

During the testing period, the business should ask:

• Are the enquiries genuine?

• Do they match the intended customer?

• Are they contactable?

• Are appointments or proposals being generated?

• Are any customers being won?

• Does the likely customer value justify the cost?

• Is the business following up consistently?

• Is there a clear reason to continue, adjust or stop?

Sometimes the correct decision is to increase investment because the commercial evidence is encouraging.

Sometimes the correct decision is to change the offer, audience or qualification process.

Sometimes the correct decision is to stop.

Good campaign management should make those choices clearer rather than simply producing more activity.

The practical starting point

A suitable Meta advertising budget begins with the economics of the business, not an arbitrary number.

Calculate what a customer is worth, estimate what you can afford to spend acquiring one, work backwards through your enquiry-to-customer conversion rate and consider whether the proposed budget can produce enough evidence to make a sensible decision.

The most important question is not:

“How cheaply can we generate leads?”

It is:

“Can this campaign generate commercially useful opportunities at a cost the business can sustain?”
