How the Wedding Planner works, step by step

Four moments from real use — the screen changes as you read.

Any evening

Open it. See where the wedding stands.

Days to go, how much of the budget is committed, how many have replied — the overview answers the three questions you actually ask.

After every quote

The budget stops being a guess.

Every cost sits against what you set aside, so 'are we over?' has an answer instead of a feeling.

As the replies come in

Guests, and who's actually coming.

The list tracks invitations, RSVPs and numbers, so catering and seating come off real figures.

Week by week

A checklist that runs to the day.

What's done, what's next, what can't slip — in the order a wedding actually happens.

What the guest list actually drives

The wedding planner holds every cost against what you set aside, on its own Budget screen. Here is the shape of it, with your number.

Cost per guest$110

At $110 a head, 150 guests is 16,500 dollars.

Budget — running on the sample data.

No account. No cloud. No catch.

It's one HTML file that runs in your browser. That single fact is what makes all four of these true.

That last one is the proof of the others. An app that keeps working with the internet switched off is an app that isn't sending anything anywhere.

Wedding Planner FAQ

Does the Wedding Planner need a subscription?
No. You buy the file once on Etsy and it's yours. Nothing renews and there's no account to keep.
What sections does the Wedding Planner have?
12 main sections: Dashboard, Budget, Guests, Checklist, Vendors, Ceremony, Reception, Day-Of, Honeymoon, Moodboard, Bridal Party, Registry. Sample data is already in all of them when you open it, so you can see how each one works before you put your own information in.
Where is my data stored?
In your own browser, on your own device. Nothing you type is sent to us — we have no server that could receive it. That also means clearing your browser data clears the app, so keep a copy of anything you'd hate to lose.
Does it work offline?
Yes. It's a single file that opens in your browser, so once you have it you don't need to be online.
What devices does it work on?
Any device with a modern web browser — Windows, Mac, iPad, Android tablet, phone or Linux. There is nothing to install and no account to create.
Can I use it on more than one device?
Yes — the same file opens anywhere. But because nothing is stored on a server, what you type on one device stays on that device; the two copies won't sync. Most people keep it on the one they actually plan on.
How do I get the file after I buy it?
It's an instant digital download from Etsy. As soon as Etsy confirms your payment the file is in your Etsy Purchases, and you can download it again from there any time you're signed in.
What exactly do I get?
The planner file itself, a Help tab built into the app so the manual travels with it, and sample data you can load and clear in one click. Light and dark mode, and print-friendly views.

You've already used it. That was the demo.

If the app above felt right, the file you buy is exactly that — minus the sample data, plus your own real life getting calmer.

Pairs well with

Budget Planner

The wedding ends. The joint finances don't. Twelve months, three budgeting methods, and the subscription audit that finds what you forgot you were paying for.
