Billing walkthrough
Sign up free, upgrade to Pro, manage or cancel — Polar handles checkout and invoicing.
Linkfor's billing runs on Polar. Polar is the merchant of record, which means they handle taxes, refunds, and the payment portal end-to-end. We never see your card.
This page walks through the full subscription lifecycle: signing up, upgrading, switching plans, and cancelling.
The plans
| Plan | Price | Sites | Mounts | Custom domain | White-label |
|---|---|---|---|---|---|
| Free | $0 | 1 | 2 | No | No |
| Pro | $1 / mo | 3 | 3 | Yes | No |
| Business | $5 / mo | 10 | 10 | Yes | Yes |
Mount counts are per owner, summed across every site they own. The pricing page has the full marketing comparison; this table is the operative product reference.
1. Sign up
Open app.linkfor.xyz/sign-up and create an account. You're on the
Free plan automatically — no credit card collected, nothing to pay.
Build a site, see if Linkfor fits, then come back here when you want
more.
2. Upgrade to Pro
Open Billing in the sidebar. The current plan card shows Free.
Click Upgrade on the Pro tier card.
A new browser tab opens at Polar's checkout page. Enter your card details, billing address, and tax info if relevant. Polar charges the card immediately and the subscription starts on the same day — prorated for the rest of the current month.
When the checkout finishes, Polar redirects you back to the dashboard
billing page. The plan card now reads Current plan: Pro and the
mount cap on the sites you own jumps to 3.
Pro plan card with the next renewal date.3. Add a custom domain
Pro unlocks the customDomains entitlement. Pop over to
Connect a custom domain for the
DNS walkthrough — once the mount goes active, your site is live on
the domain.
4. Switch plans
Both directions work. From the Billing page, click Upgrade on Business or Downgrade on Free. Polar prorates the difference automatically.
Downgrading to a tier where you exceed the new caps doesn't delete anything — your sites stay where they are, but you can't add new sites or mounts until you free up enough room or upgrade again.
5. Cancel
Click Manage billing on the billing page. That opens the Polar customer portal, where you can update payment methods, download invoices, and cancel.
Cancellation takes effect at the end of the current billing period — your Pro features (custom domains, extra sites) keep working until then. After the period closes, the account drops to Free automatically. Nothing is deleted; if you ever exceed Free's caps after the downgrade, the over-limit sites stay where they are but you can't add new ones.
Trials
If a tier is offered as a trial, the dashboard shows a notice on the billing page. During a trial, plan switching is locked — end the trial through the Polar portal first, then come back to switch.
Refunds
Refund policy lives on the terms page. The short version: pro-rated refunds for unused time are available within 30 days of a charge, contact support via the abuse-report form or email.
Receipts and invoices
Every charge generates a Polar invoice, emailed to the address on file and downloadable from the customer portal. Polar handles VAT, GST, and US sales tax based on the billing address you give at checkout.
Troubleshooting
Checkout opens but the page is blank — pop-up blocker. Try clicking Upgrade again with the blocker disabled.
Plan didn't update after checkout — webhook is processing. Refresh the billing page in 30 seconds.
Could not open portal — your account doesn't have a Polar
customer record yet (you've never paid). The portal is only useful
post-charge; until then, billing settings live in the dashboard.
