How do I get paying customers for my app?

A paying customer is a different person from a signup

A signup shows that someone clicked a free button. A payment shows that someone had a problem worth money to them. They are not the same person, and the first does not turn into the second on its own. On Prep66, not one of 31 free accounts ever went from the free plan to the checkout page. Ancestorii reached 125 signups on about £4 a day of Meta ads and had no paying customer. Today it has 177 signups, and it has never had a paying customer.

So aim at the payment from the start. Ask what makes someone pay for this today, and build the page, the price and the first post around that person. Signups that never pay covers what to do when the signups are already there and the money is not.

Who pays: someone with a problem that bites today

People pay for a painkiller, something they need now. A vitamin is nice to have, and "this is nice, I will come back to it later" means later never comes. On Prep66 every buyer had an exam booked. That is a deadline, and failing it costs a resit fee, months of waiting and a stalled licence. Next to that, £19.99 a month is not a purchase. It is insurance. On Ancestorii people said the product was meaningful and beautiful. Nobody said they needed it that day.

Two things can never be missing: a problem the buyer already knows they have, and enough reason to believe you for them to hand over money. A deadline, a painful cost of failure, bad alternatives and buyers you can reach are what make the sale fast and cheap. Will it sell goes through all six.

What the page has to say before anyone pays

• What it does, who it is for and what it costs. A Prep66 candidate could tell within thirty seconds that the site was built by someone who had sat the exams. That is why the first three paying customers all bought from the landing page, before they had touched the product.
• The price, on the page. Nobody signs up to find out what something costs. One of the answers Ancestorii got on Reddit was that the site showed no price. It is better to put some people off with a price than to put everyone off with no price. Where the price really depends on the customer, say where it starts.
• Their words, not yours. PrepAMT was written around "AMT", the trade term. Buyers search for "FAA A&P". When ChatGPT was asked for A&P prep sites it listed 29 of them and PrepAMT was not there. The whole site was rewritten in the buyers' words.
• A real checkout and a proper domain. For a cheap product people buy alone on the page, that is most of the trust they need, and it can be built in a weekend. Where the buyer is handing over health records, money or a large contract, trust is paperwork and time, and no weekend builds it.

Where the first paying customers come from

From the one place your buyers already gather, and from a story told by someone they can believe. Prep66's launch post went into r/AircraftMechanics on 14 August 2026. It told the founder's own story of sitting those exams and offered 25 free accounts in return for honest feedback. There was no link in the post. The first full price customer paid nine days later, with no discount code, and the next two paid the same way. Posting on Reddit has the rules the post followed.

Work one place at a time. In its first two months Ancestorii ran ads on Meta, Reddit, Google and YouTube, paid for a podcast slot and a magazine post, wrote pages for search and messaged creators five a day, all at once, with more than £500 gone on Meta alone. It got four signups and no payment. If the one place you picked brings nobody who pays, do not look for a second place. Look at the product and the page.

After the launch post, the pages did the work. From 27 August 2026 Prep66 recorded where each signup came from, and by 3 September 2026 it had recorded 13: 6 from ChatGPT, 5 from Google search, one from a paid Reddit ad and one direct. Getting named by ChatGPT explains how.

Payment before use, tested rather than assumed

Decide whether people can use your product before paying from what free users actually do, not from a rule of thumb. Prep66 read the records of its 31 free accounts and found that none had ever reached the checkout page, so on 5 September 2026 the free plan was removed. Signing up stayed free, so people could look inside, and nothing could be used until they paid. Eight hours after the email announcing that, the first sale of the cheaper plan came from someone who had abandoned checkout that morning.

Some products have to be used before people believe in them. Others are bought on the page before anyone touches them, as Prep66 was. Test which yours is, and judge the test on paying customers and money per visitor, never on a conversion rate alone.

Count the money by where it came from

Two numbers tell you anything: the first step that shows a stranger wants the product, and the money. Put what each one cost you beside both. On Prep66 the count started on 27 August 2026, and it showed that the free post and the pages beat the paid ad in the same days: the ad ran at £5 a day, brought one signup and no payment, and was stopped after about five days.

That record, not a feeling, is what tells you where the next hour of your time should go.

If nobody pays after all that

Check four things in order and fix the first one that fails: whether the people arriving have the problem, whether the page says what the product does, who it is for and what it costs, whether the price is being weighed against the cost of their problem, and where people drop off. Nobody signing up takes each one in turn.

If the same test has been run several times, each one big enough to show a sale if one was there, and the same nothing comes back, say out loud that there is no market here and move on. Ancestorii's founder saw in its first week that it was not working and kept going for months on hope, to a total of about £4,000 across its life. Decide the line before the test starts, and act when it is crossed.
