A QR Tipping
Platform Built on Bubble with Stripe

A nearly finished app is a peculiar kind of unfinished. Most of it works, the screens are there, and it looks ready, right up until the one thing it exists to do refuses to happen. For this tipping platform, that one thing was taking a tip: someone could scan a QR code and land on a profile, but the payment would not go through cleanly, the dashboard was awkward on a phone, and a scatter of profile and data bugs undercut trust. Our job was to get those last, load-bearing details right.

The Tipping Platform is a mobile-first web app built on Bubble.io where anyone can create a profile and receive tips through a QR code. This work took a nearly complete Bubble app and finished it: making the Stripe Checkout flow work end to end, rebuilding the dashboard to be mobile-responsive, and fixing the profile and data problems that were holding it back.

Put simply, it made the platform usable. A tipper scans a QR code, enters an amount in a popup, has a four percent platform fee added on top, and pays through Stripe Checkout; every tip is then saved against the right recipient with the amount, the tipper’s name, their message and a timestamp. Around that flow, the dashboard was rebuilt for phones and the profile system was made reliable, all verified on the version-test environment before going live.

The Starting Point: Almost Done Is Not Done

The platform arrived close to complete and stuck on the parts that matter most. The tipping flow, the whole reason the app exists, did not run reliably end to end. The dashboard, where recipients actually live, was not built for the phones most people would use. And underneath, a set of bugs made the app feel unfinished: profiles did not always save, usernames were not guaranteed unique, and a QR code pointed at the homepage instead of the profile it belonged to. Finishing meant getting the payment right and clearing the data issues, not adding new features.

The specific problems we set out to solve:

• Finish the Stripe checkout. A tipper needs to enter an amount on the profile and pay through Stripe, with the flow working reliably from start to finish.
• Handle the platform fee. A four percent fee has to be added to the tip and paid by the tipper, not taken from the recipient.
• Capture every tip. Each tip’s amount, the tipper’s name, their message and a timestamp have to be saved and linked to the right recipient.
• A mobile-responsive dashboard. The dashboard had to be rebuilt to a provided mockup and work well on phones, since the platform is mobile-first.
• Profile save and uniqueness bugs. Profiles were not saving properly, usernames were not enforced as unique, and users could not manage their profile image.
• QR and data problems. The QR code pointed at the homepage rather than the profile, and the State field was the wrong data type with no dropdown.

The Build: Get the Tip Working, Then Fix the Foundations

The tipping flow came first, because a tipping platform that cannot take a tip is not a platform. On a profile page, a popup lets a tipper enter an amount; a four percent platform fee is added on top and paid by the tipper; and the payment is taken through Stripe Checkout. When the payment succeeds, the tip is saved against the recipient and the tipper is sent to a Thank You page. Wiring a payment provider cleanly into a Bubble app is a common thread in our Bubble.io app development work, where the visible flow has to line up exactly with what the payment provider is doing behind it. From the tipper’s side, it runs in a clear order:

1. Scan the recipient’s QR code and land on their profile page.
2. Enter a tip amount in the popup.
3. Have the four percent platform fee added on top, paid by the tipper.
4. Pay through Stripe Checkout.
5. Have the tip saved against the recipient with the amount, tipper name, message and timestamp.
6. Arrive on a Thank You page confirming the tip went through.

With the flow working, the rest was polish and repair. The dashboard was rebuilt to the provided mockup and made fully responsive, so recipients can see their tips and manage their profile comfortably on a phone. Profile saving was fixed and usernames are now enforced as unique, users can change or remove their profile image, the QR code was corrected to link straight to the right profile, and the State field was converted to the proper data type with a dropdown. Getting a nearly complete product across the line like this is the heart of MVP development, where the value is in shipping a reliable core, not in piling on more scope.

Technical Architecture

The app is built on Bubble.io, mobile-first, with a compact set of pieces behind the tip flow.

• Profiles and QR codes. Each recipient has a profile with a QR code that links directly to it, so a scan lands a tipper exactly where the tip should go.
• Tip popup and fee logic. A popup on the profile takes the amount and adds the four percent platform fee on top, paid by the tipper, before payment.
• Stripe Checkout. Payment is taken through Stripe Checkout, so the sensitive part of the flow runs on Stripe rather than being rebuilt in the app.
• Tip records. The Bubble database saves each tip against its recipient with the amount, tipper name, message and timestamp, so nothing is lost and every tip shows up for the right person.
• Confirmation. A successful payment redirects the tipper to a Thank You page, closing the loop on a clear note.
• The mobile dashboard. A responsive dashboard, rebuilt to the mockup, shows recipients their tips and lets them manage their profile on a phone.

All of it runs on a no-code and low-code development foundation, which is part of why finishing the app was quick: the platform already carried the database, the workflows and the Stripe connection, so the work could concentrate on the payment flow and the fixes rather than rebuilding plumbing. Everything was tested on the version-test environment before going live.

Challenges Solved

Each problem was resolved at the root rather than patched over. The Stripe flow was completed end to end, with the four percent fee added cleanly and paid by the tipper, so tipping is reliable. Every tip is now recorded against its recipient with the amount, name, message and timestamp, so nothing slips through. A Thank You page gives each tipper a clear confirmation. The dashboard was rebuilt to the mockup and made fully responsive for the phones the platform is actually used on. And the profile and data faults, unreliable saving, clashing usernames, unmanageable images, a misdirected QR code and a mistyped State field, were each fixed properly.

Handling money, however small the amount, is where reliability stops being optional. Getting the fee, the payment and the record exactly right is the same discipline behind work for fintech and payments products, where a flow that is nearly correct is still broken. Fixing the data at the root, rather than patching symptoms, is what makes the platform trustworthy to take a payment.

The Result

The result is a working, polished tipping platform. Tips flow through Stripe with the fee handled and every tip recorded against the right recipient; the dashboard is clean and responsive on mobile; and the profile, QR and data problems are resolved and verified on the version-test environment. A nearly complete app became a finished one, ready for people to scan, tip and be paid.

If you have a Bubble app that is close but not quite shippable, a payment flow to finish, a dashboard to fix, bugs to clear before launch, you can hire JavaScript developers who are comfortable taking a build the last mile, or tell us where your app is stuck and we will map out what it takes to get it live.

Frequently Asked Questions

How does the QR tipping flow work?

A tipper scans a recipient’s QR code and lands on their profile, enters an amount in a popup, and pays through Stripe Checkout. A four percent platform fee is added on top and paid by the tipper, and after a successful payment the tipper is taken to a Thank You page confirming the tip.

Who pays the platform fee on each tip?

The tipper. A four percent platform fee is added on top of the tip amount before payment, so the recipient receives the full tip and the fee is never deducted from what they are given.

What information is saved with each tip?

Every tip is saved against the recipient with the amount, the tipper’s name, their message and a timestamp. That means recipients see exactly who tipped, how much, what they said and when, and no tip is lost.

Can Stripe Checkout be integrated into a Bubble.io app?

Yes. This platform runs its payments through Stripe Checkout inside a Bubble.io app, with the tip amount and the four percent fee handled in the app and the payment itself taken securely on Stripe. The full flow was tested on the version-test environment before going live.

Can you finish or fix an existing Bubble app rather than build from scratch?

Yes. This project took a nearly complete Bubble app and finished it: completing the Stripe flow, rebuilding the dashboard for mobile, and fixing profile saving, unique usernames, image management, the QR link and a mistyped State field, so the platform was ready to launch without a rebuild.
