Updating your product: versions, fixing mistakes, and telling past buyers

Every product has mistakes in it. A typo on page six. A form field that won't let you type. A link that worked last month and doesn't now. That's normal. What matters is what you do once you find out.

The nice thing about digital products is that you can fix them. You don't have a warehouse full of misprinted boxes. You have one file you can correct.

By the end of this lesson, you'll have a simple way to number your versions, decide what's worth fixing, update the file without breaking anything, and tell past buyers what changed.

The short version

• Give every release a version number and keep a short written list of what changed.
• Fix real mistakes fast, and send the fixed version to everyone who already bought.
• Tell past buyers plainly what changed and how to get it. Don't hide fixes or oversell updates.

Why bother with versions

A version is one saved release of your product. When you change it, you make a new version. A version number is the label that tells you and your buyers which one they have.

Without version numbers, things get messy fast. A buyer emails to say page four is wrong, and you have no idea if they have the old file or the new one. You end up with five files on your computer named "final," "final2," and "final-REAL." We've all been there.

Version numbers fix that. They also show buyers you're keeping the product in good shape.

Step 1: Pick a simple numbering system

You don't need anything fancy. Here's one that works for most small products:

• 1.0 is your first full release.
• 1.1, 1.2, 1.3 are small fixes: typos, broken links, a field that didn't work.
• 2.0 is a big change: new sections, a new layout, or something that works differently.

Put the version number somewhere the buyer can see it. The bottom of the first page or the last page works fine. Add it to the file name too, like "expense-tracker-v1-1.pdf."

Then keep a changelog. That's just a running list of what changed in each version. It can live in a plain document:

• v1.2: Fixed the total field on the summary page. Updated a broken link on page 3.
• v1.1: Fixed typos on pages 2 and 7.
• v1.0: First release.

That's it. Short, dated if you like, and honest.

Step 2: Decide what to fix and when

Not every change is the same. Sort them into three piles.

Fix right away

These are mistakes that stop the product from working or could mislead someone:

• Form fields that don't work
• Math or totals that come out wrong
• Wrong information, like an outdated instruction
• Broken download links
• Pages that are missing or out of order

Don't wait on these. Fix them, release a new version, and tell buyers.

Fix in the next small update

These are real but minor:

• Typos
• Small layout problems
• Confusing wording

Collect a few, then fix them together in one update so you're not emailing buyers every other day.

Save for a bigger version

These are ideas, not mistakes:

• New sections or pages
• A different design
• Features people asked for

Write them down and think about them later. Not every request needs to happen.

A broken product is a fix. A better product is an update. Don't confuse the two.

Step 3: Make the update without breaking things

Changing a file is easy. Changing it without breaking something else takes a little care.

1. Keep a copy of the current version before you touch anything. Name it clearly, like "v1-1-backup."
2. Make your changes in a new copy.
3. Test the whole thing, not just the part you changed. Fix one form field and you can accidentally break another.
4. Update the version number inside the file and in the file name.
5. Write the changelog entry.
6. Replace the file wherever buyers download it: your store, your delivery email, your download page.
7. Download it yourself the way a buyer would, and check that you get the new version.

That last step catches more problems than you'd think. If you need a refresher on how delivery works, see Delivering a digital product.

Step 4: Tell past buyers

This is the part a lot of sellers skip. Don't.

People who already paid deserve the fixed version, especially if the old one had a real mistake. Getting it to them without being asked is one of the simplest ways to earn trust.

How to reach them

• Most store and checkout platforms let you see a list of past buyers, and some let you email them or re-send the download.
• If buyers joined your email list when they bought, you can send them a note there.
• If neither works, put a clear note on the product page explaining how past buyers can get the new version.

What to say

Keep it short and plain. Something like:

"Hi. I found a mistake in the expense tracker: the total on the summary page wasn't adding up the last month. I've fixed it in version 1.2. You can download the new version here. Your old file will still open, but the summary total won't be right, so I'd switch to the new one. Sorry about that. Reply if anything else looks off."

Notice what that does. It says what was wrong, admits it, says what's fixed, tells them how to get it, and invites feedback. No drama, no excuses.

What not to say

• Don't call a bug fix an "exciting upgrade."
• Don't hide a real mistake inside a vague "improvements" line.
• Don't use a fix as an excuse for a sales pitch. If you mention something else you sell, keep it to one line at the end, or skip it.

Step 5: Decide your update policy and say it

Buyers want to know what they get after they buy. Decide this once and write it on your product page.

Some common, honest options:

• Fixes are always free. If something's broken, every buyer gets the fixed version. This one should be the minimum.
• Small updates are free. Version 1.x updates go to everyone.
• Big new versions may be separate. A 2.0 that's really a new product might be sold separately, maybe with a discount for past buyers.

Whatever you pick, say it before people buy and stick to it. Changing the rules after someone has paid is a quick way to lose them.

Do this next

• Add a version number to your current product, inside the file and in the file name.
• Start a changelog document with your first entry.
• Make a list of known issues and sort them into fix now, fix soon and save for later.
• Check how your store or checkout lets you contact or re-deliver to past buyers.
• Write a short, plain update email template you can reuse.
• Write your update policy in one or two sentences and add it to your product page.

Mistakes happen. Fix them, own them, and send the good version to the people who trusted you first.
