Find the bottleneck before choosing a channel

Start with where business is being lost, not where the dashboard looks busiest.

Trace a few recent enquiries from first contact to completed work. Are too few suitable people finding you? Are interested visitors leaving without enquiring? Or are good enquiries waiting for a response? Each diagnosis points towards a different use of the budget.

• Too few suitable enquiries: consider a focused content or visibility test.
• Interest without enquiries: examine the offer, service explanation and next action.
• Enquiries without bookings: examine response handling, qualification and follow-up.
• Bookings you cannot fulfil: address capacity before funding more demand.

Use reach, reactions and website visits as clues, not spending instructions. Ask what changed further along the customer journey. If that link is missing, investigate before treating a bigger audience as the answer.

Estimate what another customer contributes

Use the amount left after serving the customer, rather than the headline sale.

For this decision, estimate customer contribution as sales income minus costs directly associated with fulfilling that work. Depending on your business, include materials, subcontractors, transaction charges and additional delivery labour. Keep the proposed marketing spend separate so you can compare it against that contribution.

Use recent completed jobs to build a cautious estimate. If job types differ substantially, compare them separately. Do not give a small one-off job and a larger ongoing contract the same assumed value.

Start with the first purchase. Add repeat business only where your own records support it, and show that assumption separately. Otherwise, an optimistic future relationship can make a weak immediate decision look attractive.

Compare the next investment, not past averages

The useful question is what another £500 might change.

A campaign’s past results do not tell you what its next increment will achieve. Ask whether another investment would reach new suitable customers, improve an existing step or simply repeat work for people already likely to buy.

Write down what you expect without the investment, then what you expect with it. The difference is your estimate of additional customers. Use a cautious and a more favourable scenario rather than presenting one uncertain number as a forecast.

Do not count the same expense twice. Treat money already spent separately from the new decision, and check whether any existing commitment can actually be changed. The aim is to compare choices you can still control.

Check the evidence and cash timing

Keep two questions separate: will this help, and can you fund the wait?

For evidence, look for a traceable path from activity to enquiry, booking and completed work. Note what remains uncertain: customers may have encountered you elsewhere, an offer may have changed, or the period may have been unusually busy.

• Stronger basis for a decision: repeated observations, recorded customer sources and completed work.
• Useful but incomplete: enquiries with an identifiable source but no confirmed outcome.
• Exploratory only: engagement figures without a connection to suitable enquiries.

For cash timing, map when you would pay for marketing, incur delivery expenses and receive customer payments. Use your own booking patterns and payment terms. A positive contribution estimate is not enough if the spending would leave you unable to meet existing commitments while waiting.

Where evidence is thin, lower your confidence rather than disguising uncertainty with precise calculations.

Make a bounded spending decision

Turn the comparison into a small, reviewable commitment.

ARYS provides tools to record, organise and track marketing leads, helping you keep enquiries and follow-up activity together. It is currently opening early access to selected businesses; explore the available tools rather than assuming every integration or reporting connection is live.
