--- title: Coupons, refunds and limits description: Discount coupons, how refunds work on Insy, sales limits, availability windows, waitlists and custom checkout fields. --- A few tools let you shape the offer: discount codes, a refund policy, limits on quantity and timing, and extra questions at checkout. ## Discount coupons A coupon is a code a buyer types at checkout for a **percentage off**. You control: - **The code** and the **percentage** it takes off. - **Which options** it applies to — attach it to specific priced options. - **How long the discount lasts** on a subscription — one payment, a set number of months, or forever (as long as the subscription runs). - **An expiry date** and a **maximum number of uses**, both optional. Leave them off and the code never expires and has no usage cap. > **Coupons are percentage-based** > > Coupons take a percentage off, not a fixed amount. For a "10 PLN off" deal, work out the equivalent > percentage or set a lower price on the option directly. ## Refunds > **There is no refund button for creators** > > Refunds on Insy are **not self-service** — you can't issue one from your dashboard. What you can do > is publish a **refund policy** buyers see at checkout: turn refunds on and state a "no questions > asked within N days" window. That window sets expectations, but it's a promise, not an automated > action — honouring it is handled manually through support, not by a button you press. So: decide whether to advertise a refund window, set it if so, and route any refund request through Insy support. A product with no refund policy simply doesn't show one. ## Sales limits You can cap how many units sell, at two levels: - **Per option** — a limit on a single priced option. Once reached, that option stops selling. - **Whole product** — a limit across the product, whichever option is chosen. Leave a limit unset and that level is unlimited. Useful for a cohort with fixed seats or a scarce release. ## Availability windows A product can have a start and an end for when it's on sale: - **Available from** — before this, the page is visible but the buy button is closed. - **Available until** — after this, it stops selling. Outside the window the page still shows, so you can build anticipation before a launch or leave a sold-out page up after one — buyers just can't check out until (or after) your dates. ## Waitlists When an option is unavailable — sold out, or not yet open — a buyer can **join its waitlist** by leaving their email. When it becomes available again, Insy emails everyone on the list so they can come back and buy. It turns a closed page into a way to capture demand instead of losing it. ## Custom checkout fields Add your own fields to the checkout to collect what you need from each buyer. Each field has a label, can be marked **required**, and is one of these kinds: | Field | For collecting | | --- | --- | | **Text** | A free-text answer — a name, a handle, a note | | **Phone** | A phone number | | **Address** | A postal address | | **Consent** | A checkbox the buyer must tick; the label holds the full consent text | Use a **consent** field for terms, a licence agreement or a marketing opt-in — the label is the full wording the buyer agrees to. Keep required fields to what you genuinely need; every extra one is a step between the buyer and the sale. Start here if you have not built the product yet. Get your earnings out and get discovered by new buyers.
