I just want a really good checkout tool

Every checkout tool starts in the same place: take the payment, take it well. Then it adds a page builder. Then a members area. Then email broadcasts, a course player, a community tab. Two years later the thing you bought to process payments is asking you to rebuild your website inside it.

The problem is not that those features are bad. It is that they are somebody else's job, done worse. You already have a site you like, an email tool you know, and a place your customers log in. What you cannot easily replace is the twenty seconds where somebody's card is out.

So the questions worth asking a cart are narrow ones. Can I put an add-on in front of a buyer while they are already paying? Can I offer one more thing after the charge without asking for the card again? When a renewal fails, does anything happen, or does the customer just quietly disappear?

And then the one everybody forgets until they need it: can I get the data out. Not a revenue chart — the rows. What was bought, when, at what price, what came with it, and which link brought them. In a spreadsheet, or through an API, on a Tuesday afternoon when you have a question nobody built a dashboard for.

That is the whole of what Swipefast tries to be. The revenue layer, and the data underneath it. Everything else, it hands to the tools you already picked.
