Why a Quarterly Review Beats an Annual One

Most small business owners set a marketing budget once a year and then leave it alone. The problem with that approach is that twelve months is a long time to keep funding something that quietly stopped working in February. A quarterly review gives you a natural checkpoint four times a year — often enough to catch a failing channel early, but not so often that you are constantly tinkering.

If you are spending £500 a month on marketing, that is £6,000 a year. Even small shifts in where that money goes can make a noticeable difference to the number of enquiries landing in your inbox. The aim is not to become an accountant. It is simply to know which parts of your marketing are earning their keep and which are coasting on habit.

Gather the Numbers Before You Decide Anything

Set aside an hour at the end of each quarter to pull together a simple one-page summary. What you track depends on your business, but most owners find these five figures cover it:

• Total spend per channel — divide your marketing budget by activity. Social ads, print, directory listings, email software, sponsorship, whatever applies.
• Enquiries or leads per channel — count them, even roughly. A tally in a spreadsheet is fine.
• Cost per enquiry — spend divided by enquiries. This single number quickly exposes which channels are expensive.
• Conversion rate — how many enquiries turned into paying customers, by channel if you can manage it.
• Revenue attributed — even an estimate helps you see whether a channel brings in small jobs or the work you actually want.

Be honest about the gaps. If you cannot attribute an enquiry to a channel, say so and write "unknown". Guessing inflates whichever channel you happen to like most.

Match Spending to Reliable Enquiries

Once the numbers are in front of you, put each channel into one of three buckets: earning, holding or draining. Earning channels produce enquiries at a sensible cost and convert well. Holding channels are steady but unremarkable. Draining channels cost money without bringing in anything you can point to.

The instinct is often to cut everything in the draining bucket straight away. Resist that for a moment. Some channels — a trade directory, a local sponsorship, a slow-building email list — take two or three quarters to prove themselves. Ask whether the channel has had a fair run. If it has been six months or more with no measurable return, that is a fair signal to pause it.

Then shift the money. Take the budget freed up from the underperformers and move it to the earning channels, even if that feels like putting all your eggs in one basket. In practice, most small businesses find that two or three channels do the heavy lifting, and topping them up produces more enquiries than spreading thin across six.

A Practical Way to Decide What Stays

When you are weighing up a channel, four questions usually settle it:

• Is the cost per enquiry affordable? Work out the maximum you can pay per lead and still make a profit. Anything above that needs a very good reason to stay.
• Does it bring the right kind of customer? Cheap leads that never convert are not cheap at all.
• Is the trend moving in the right direction? A channel improving quarter on quarter is worth patience; one sliding steadily is not.
• Would you miss it? If pausing it would genuinely leave a gap you could not fill elsewhere, keep it — but mark it for close attention next quarter.

Write down your decision and the reason for it. A short note like "paused local magazine — £300 for two enquiries in six months" is worth more than a vague memory, especially when you revisit it three months later.

Keep It Light and Repeatable

The best quarterly review is one you will actually do. Keep the format the same every time: same spreadsheet, same five figures, same three buckets. That way the comparison is like for like and you can spot patterns across the year.

It also helps to involve whoever handles the enquiries day to day. They often know which leads were genuine, which were tyre-kickers, and which channel the good ones mentioned when they called. That kind of ground-level detail rarely shows up in a spreadsheet but changes the picture completely.

What to Do With the Money You Free Up

Pausing a channel does not mean you have to spend the savings elsewhere straight away. Options worth considering:

• Increase the budget on your best performer and see whether the extra spend keeps producing. Test in small increments so you can tell when it stops working.
• Fix the weak link instead. If enquiries are plentiful but conversion is poor, the money may be better spent on follow-up, quoting or your website.
• Test one new thing with a capped budget and a clear deadline. Give it a quarter to show something before the next review.
• Bank the difference. Not every quarter needs to be spent in full. A quieter trading period is a reasonable time to hold cash back.

Do this four times a year and the effect compounds. You stop paying for marketing out of habit, you slowly concentrate your spend where enquiries actually come from, and you build a record of what works for your business specifically — which is far more useful than anyone else's advice, including mine.
