How to sell digital products and services online

You made a thing, or you know how to do a thing, and neither one fits in a box. Nothing to weigh. No courier to argue with, no packaging to buy, no stock sitting in your mum's spare room. So this should be the easy version of selling.

It isn't. And the reason is that "digital" quietly covers two businesses that behave nothing alike.

Both need the same three parts: a page with a price on it, a way to take money, and something that happens the moment the money lands. For a file, that something is a download. For an hour, it's a slot coming off your calendar. That is the entire difference, and it decides your pricing, your workload, and how large this thing can ever get. Tobi in Lagos sells a pitch deck template pack for ₦12,000 and can sell it four hundred times without changing his Tuesday. Rhea in Manila tutors chemistry at ₱600 an hour and cannot sell more than about twenty of them a week without losing her mind.

Same platform. Same effort to set up. Completely different animals.

A file can be copied. An hour cannot be restocked.

This sounds obvious written down. It stops being obvious the second you're deciding what to charge.

A file has zero marginal cost. Tobi's second sale costs him nothing. His hundredth costs him nothing. There is no stock level, no reorder point, no "sold out". If nobody buys the template pack on Thursday, Thursday cost him nothing either. The file just sits there, and the only thing he loses is the sale he didn't make.

An hour is the opposite in every direction. Rhea's Tuesday 4pm slot exists once. If nobody books it, it does not roll over into Wednesday. It's gone, permanently, and it took her whole Tuesday afternoon with it because she couldn't schedule anything else around a maybe. Her inventory expires hourly, forever, whether she's watching or not.

That's the asymmetry underneath everything else on this page. Files fail by not being found. Hours fail by not being filled, and an unfilled hour is a loss you take in real time.

There's a second asymmetry that matters just as much: a file can be given away by the person who bought it. An hour can't be. Nobody has ever forwarded a haircut to a WhatsApp group. The moment your file lands on a buyer's phone, it is physically theirs, and you should decide what you think about that before it happens rather than after. The honest version of that decision is in what you can and can't do about people sharing your paid files, and the short answer is that you get speed bumps, not locks.

What zero marginal cost actually changes about your day

If you sell files, your job is not making files. It's getting people to the page.

That feels wrong for about six months. You spent forty hours on a template pack, so it seems reasonable that the next forty hours should also go into making things. They shouldn't. The pack you already have will earn more from an afternoon spent writing about it than from an afternoon spent adding a fifth colourway to it.

Practical consequences, in the order they'll hit you:

• Volume is your only lever, so traffic is your only real problem. Doubling the price of a thing nobody has seen doubles nothing.
• Refunds cost you nothing except pride. If someone asks, refund them. They keep the file either way, and arguing about ₦12,000 in a DM will cost you more than ₦12,000 of your afternoon.
• You can sell while asleep, in theory. In practice, only if the payment side is automated too. More on that below, because it's the part everyone gets wrong.
• One file can quietly become the whole business. Most people who sell digital products make one thing that sells and four that don't. You cannot tell in advance which is which, which is an argument for shipping the first one before it's finished.

The thing that will surprise you: your best seller is usually the smallest, dullest, most specific file you made. Not the ambitious one. A one-page invoice template that solves an annoying afternoon outsells a beautiful sixty-page guide about running a business, every time, because the invoice template has an obvious moment where someone needs it.

What a calendar costs you that a file never will

Selling time means selling a promise about the future, and the future is where all your problems live.

You are not selling an hour. You're selling an hour plus the setup before it, the notes after it, the travel to it if you go to them, and the mental space it occupies for the two days beforehand. Rhea blocks 60 minutes for a session she calls "one hour". The session is 50 minutes. The other 10 are her writing down what the student got wrong so the next session isn't wasted.

If you price the 50 and forget the 10, you've given away a sixth of your week for free.

Then there's the part nobody mentions in the ads: a booking is an interruption you agreed to in advance. Three sessions spread across a day is not three hours of work. It's a whole day you can't do anything else with. Two back to back is three hours of work and a free afternoon. The scheduling matters more than the rate does, and that's a lesson most people learn the expensive way. If you're setting up a booking page this week, the settings that actually protect your life are covered in how to take bookings for a service without a receptionist. The single most important one is the notice period, and you want it at 24 hours.

Then, no-shows. A file has never failed to turn up. Roughly one booking in ten will, and every one of them costs you the full slot with no revenue attached. That's what deposits are for, and why service businesses that don't take deposits are quietly running at a discount they never agreed to.

The two pricing mistakes are mirror images of each other

Mistake one: pricing a file like an hour. "This took me forty hours, my time is worth $50, so the ebook is $2,000." Nobody will pay it. The forty hours you spent making the file are a sunk cost the buyer will never see, never care about and never reimburse. They're paying for what it does for them in the next twenty minutes.

Mistake two: pricing an hour like a file. Racing your rate down because a competitor is cheaper, as though you can make it up on volume. You can't. There is no volume. Your ceiling is a fixed number of hours and dropping your rate by 20% means you need 25% more of a thing you have a hard limit on.

Files scale by selling more. Hours scale by charging more, or by turning the hour into a file.

Prices live in bands, and the band matters far more than the exact number. A ₹499 template and a ₹549 template will sell about the same. A ₹499 template and a ₹4,999 template are different products with different buyers, even if the file is identical. If you've never set a price on something intangible and you're staring at the box, pricing a digital product for the first time walks through why $7 and $47 both work and $23 almost never does.

You cannot make it up on volume when volume is the thing you don't have.

Two shops, same tool, opposite shapes

Tobi, Lagos. Sells three template packs at ₦12,000, ₦18,000 and ₦35,000. Buyers pay by bank transfer, mostly. He gets maybe 200 people a month on the page and converts a handful. His work is Instagram carousels, a newsletter he writes badly and sends anyway, and answering "does this work in Google Slides" fourteen times a week. His marginal cost per sale is zero, so his margin is whatever the transfer fee isn't. He hasn't made a new pack in five months and his revenue went up.

Rhea, Manila. Sells 60-minute chemistry sessions at ₱600, and a four-session block at ₱2,200 which is a small discount and a big deal because it stops her rebooking the same student every week. She takes a ₱200 deposit by transfer against her GCash details, which she's written into the payment instructions on her page. She has 18 bookable hours a week and she's full most weeks. Her problem isn't traffic. It's that the only way she earns more is to raise ₱600 to ₱750, which she has been putting off for a year.

Two useful things fall out of this comparison.

Tobi's business is fragile in one way: everything depends on people finding the page. If his Instagram reach dies, so does the shop, and there's no relationship to fall back on. Rhea's business is fragile in a completely different way: it depends on her being awake and well. She had flu in March and lost ₱4,800 in a week she'll never get back.

The fix for both is the same move in opposite directions. Tobi should sell an hour. Rhea should sell a file.

What has to happen in the ninety seconds after someone pays

The buyer has just given you money and is now sitting there, slightly nervous, wondering if they've been robbed. This is the moment your whole shop is judged on.

For a file, the buyer expects the download to appear immediately. Not an email in an hour. Immediately, on the page they're already looking at, with a filename that looks like something a person named on purpose. On Sailo, digital files unlock on payment confirmation, and you can set a download limit and an expiry date on each one. Five downloads and 30 days is a sensible starting pair. One download is not: the first thing that happens with a one-download limit is that someone's mobile data drops halfway through a 40MB file and now you're both in a DM about it.

For a booking, the buyer expects a confirmation with the date, the day of the week, the time, and the address or the call link. Write "Tuesday 14 August, 3pm" and not "the 14th at 3". Including the day name prevents an entire genre of no-show where someone had the right date and the wrong Tuesday in their head.

The mechanics of getting a PDF from your laptop to a stranger's phone without a website, including what to say when they claim the download failed, are in how to sell a PDF without a website.

On a manual rail, you are the automation

Here's the limitation that matters most on this page, and it's a real one.

"Unlocks on payment confirmation" means it unlocks when the payment is confirmed. If you take card payments, that's the card network telling you, in seconds, at 3am, without you. If you take bank transfer, cash, or a transfer against a UPI ID or an M-Pesa till you've typed into your payment instructions, then the thing confirming payment is you. A person. With a phone. Who is sometimes asleep.

Sailo cannot tell you a bank transfer arrived. Only your bank can. So the buyer in Nairobi who pays at 11pm gets their file when you check your banking app in the morning, and if you don't say that on the page, they will spend those nine hours assuming they've been scammed.

Two things fix most of it. Say the lag out loud, in writing, before they pay: "Files are released once I've confirmed your transfer, usually within a few hours and always by 10am." And check twice a day at times you actually keep, rather than promising instant and delivering whenever.

The alternative is card payments, which on Sailo need a connected Stripe account, and cost 1–3% of the goods on top of whatever Stripe charges. At a ₦12,000 template that commission is about ₦60. The subscription is the real cost, and at low volume it's a bad trade. Manual rails take no Sailo commission at all. Slower, cheaper, and yours to run.

Selling both: the file feeds the hour, or the hour funds the file

Most people who do well at this end up with one of each, and the order they built them in is the interesting part.

If you already sell time, your file writes itself. Every question you answer twice is a file. Rhea has explained mole calculations 300 times; that's a workbook, and it's the same workbook every time. She can sell it at ₱450 to people who will never book her, and hand it free to people who do, and it costs her nothing either way.

If you already sell files, an hour is the highest-margin thing you can add, because you're not competing on it. Tobi charging ₦40,000 for a 90-minute deck review is not competing with anyone; he's selling access to the person who made the thing they already bought. Cap it. Four a month, not unlimited, or the calendar eats the business that was working fine without it.

The most common shape this takes is a course, which is really just a set of files with a booking bolted onto it. You do not need a course platform for that, at least not at first, and the point at which you genuinely do is worth knowing before you pay for one. Selling a course without a course platform covers where that line sits.

The boring things that will bite you

Refunds on files. They keep the file. Decide your policy now, write it on the page, and make it generous, because chasing it is not worth your afternoon. "Refunds within 14 days, no questions" costs you a handful of sales a year and buys you every buyer who was hesitating.

Refunds and cancellations on bookings. Not generous. Free cancellation up to 24 hours before, deposit kept inside 24 hours. You cannot refill a slot at 8am for the same day and the deposit is the only thing standing between you and an empty Tuesday.

Tax on digital goods. Rules on cross-border digital sales vary by country and some of them apply from the first sale, not from some comfortable threshold. Look up your own position before you have a year of sales to unpick. This is not the article that can tell you, and anyone who tells you confidently without knowing where you live is guessing.

Scope, on services. Write the duration and what's included in the listing itself, not in your head. "60 minutes, one topic, materials sent after" ends the argument before it starts.

Pick the one that matches the next six months

If your next six months have more time than audience, sell time. Book the hours, charge properly, take a deposit, and use the sessions to find out what people keep asking you. That's your file, and you'll have written most of it by accident.

If your next six months have more audience than time, sell a file. Make the small dull specific one first, price it in a band rather than at a number you agonised over, and put it up before you've finished being embarrassed by it.

Then set your notice period to 24 hours, set your download limit to five, and write the sentence about how long payment confirmation takes. Those three settings will save you more grief than anything else you do this month.

The rest of this cluster

On the files side: selling templates and presets, where the support questions are the real cost; delivering large files to buyers when a zip is too big for the buyer who needs it most; offering a free sample of a paid file; bundling digital products; and updating a file people already bought, which nobody writes about and everybody hits.

On the time side: selling consultations by the hour, rescheduling and cancellations with wording you can copy, and selling a newsletter or paid community if you want something recurring, with a warning that a community is a job rather than an asset.
