QUESTIONS, ANSWERED.

We use Stripe as our payment partner to help ensure a properly secured payment process for both you and your customers. To sell on Uberflux, you need a Stripe account — it's quick and easy to sign up. Once you have an approved Uberflux maker account, head to the payments page to connect your Stripe integration. You can sign up for Stripe right there if you don't already have an account, or link an existing one.

A flat 4.5% platform fee per sale — no listing fees, no monthly subscription. On top of that, Stripe's standard payment processing (2.9% + $0.30 in the US for credit cards) is billed by Stripe, not Uberflux. The only other fee is an additional $0.50 fee for any transaction that includes tax. This is discussed above.

Whether you should register to collect sales tax depends on where and how much you sell — and we're not tax professionals, so we can't advise you on that. Please talk to a qualified tax advisor about your situation.

What we can tell you is how Uberflux and Stripe behave:

• If you register to collect tax (you do this in your Stripe tax settings) at the destination address or drop location, Stripe automatically calculates the right tax at checkout, collects it from the buyer, and charges $0.50 per transaction for each sale it calculates tax on. This fee is billed by Stripe, not Uberflux.
• If you aren't registered at the destination address or drop location, no tax is calculated, nothing extra is collected from buyers, and there's no additional $0.50 charge.

You're the merchant of record for your sales, so registering, collecting, and remitting sales tax is your responsibility. If you are registered to collect tax at a drop location, it is important that you enter the correct address or at least the city, state/province/region, and postal code in the drop editor so taxes can be calculated properly.

Buyers pay through your own connected Stripe account, and Stripe pays out to your bank on its normal schedule. Uberflux never holds your money.

Yes. Offer drops instead of shipping and customers can pick the event at checkout. The buyer gets a QR code in their receipt; you scan it at the drop to fulfill the order on the spot.

When a buyer orders for pickup at a drop, their receipt includes a QR code. At the drop, scan that code with a mobile device — it opens a link where you can mark the order as fulfilled on the spot. Scan, confirm, hand over the goods.

Yes. Before the drop, download the drop's CSV from your seller dashboard — it lists every order with its order number and 8-digit verification code. At the drop, match the order number and verification code printed on the buyer's receipt against the CSV to confirm the order and keep track of which ones you've fulfilled. No internet or scanning required.

Yes — the broadcast tool lets you message every buyer of a specific badge or every buyer registered for a particular drop in one shot. Open Messages in your seller dashboard, hit "Message Buyers", pick your audience (a badge or a drop), write your update, optionally attach up to 6 images, and send. Each buyer receives it in their Uberflux inbox and can reply directly — keeping the conversation organized in one place rather than scattered across email. From the Sent Broadcasts tab you can see every broadcast you've sent, how many buyers received it, and how many have replied.

When a buyer reaches the payment page, the items in their cart are reserved from your inventory for up to five minutes. If they don't finish paying within that window, the reservation expires and the items go back into inventory automatically. If a buyer does complete payment but the stock sold out during their checkout — say someone else bought the last one — the order is automatically cancelled and refunded, so you're never on the hook to ship something you don't have.

You handle refunds and disputes from your Stripe dashboard, and Uberflux mirrors whatever you do there onto the order automatically — including the effect on your inventory.

Our recommended course of action is always the same: if an order hasn't been fulfilled yet, refund it as soon as a fraud warning or dispute appears. You get the stock back immediately, and for a fraud warning you head off the chargeback and its fee entirely. There's no upside to waiting — holding an unfulfilled flagged order only risks shipping goods you won't be paid for.

• Refunds — Refund a charge from your Stripe dashboard, in full or in part. A full refund on an order you haven't fulfilled yet cancels the order, marks it refunded, and returns those units to your available stock (a drop order also stops working at pickup). If you'd already shipped or handed off the goods, the order is marked refunded but inventory is left untouched — those units are gone. A partial refund is only flagged: it never cancels the order and never changes inventory.
• Chargebacks (disputes) — When a buyer disputes a charge with their bank, Uberflux flags the order as a chargeback and, if it hasn't been handed off, disables fulfillment so you don't ship goods you may not be paid for (drop orders can't be scanned at pickup). For an unfulfilled order we recommend refunding rather than contesting — you won't win a dispute on goods that were never delivered. If you do win, the order becomes fulfillable again; if you lose or refund, it's cancelled and any unfulfilled units return to your available stock. If the goods were already shipped or picked up before the dispute arrived, the order is flagged but inventory is left untouched.
• Early fraud warnings — Sometimes a card issuer flags a charge as likely fraudulent before any formal dispute. Uberflux marks the order "fraud warning" and holds fulfillment. If you haven't fulfilled it, refund it — that cancels the order, returns any unfulfilled units to stock, and avoids a chargeback and its fee.
• Inventory, specifically — Units return to your available stock only when an unfulfilled order is definitively reversed: a full refund, or a dispute you lost. While a fraud warning or a dispute is merely open, the units stay held (counted as sold) so they can't be oversold if the order turns out valid. Anything already shipped or picked up is never returned to stock.

No. There's no listing pre-approval — connect your Stripe account, create your listing, and it's live.

Product descriptions support Markdown, so links use standard Markdown syntax: [link text](https://example.com). Put the text you want to show in square brackets, then the URL in parentheses right after, with no space between them. Markdown also gives you headings, bold, italics, and lists in your description.
