Back-in-stock, done fairly · for apparel & footwear

Sell the restock,
not the apology.

Most apps email your whole waitlist at once — the restock sells out in minutes and hundreds of shoppers get a link to nothing. Fairstock notifies only as many people as units you got back, in the order they signed up.

Why we're building this

Restock alerts are quietly costing you customers.

“It emailed 400 people for 6 units.”

Six buy, 394 click a sold-out page and feel tricked. Your restock becomes a support fire, not a win.

“It fired for a draft product.”

Wrong sends for hidden, archived, or always-in-stock variants. Each one is a shopper who trusts your emails a little less.

“My Klaviyo bill jumped $300.”

Every back-in-stock signup counts as a billable profile. One viral drop quietly bumps you into the next tier.

How it works

Four steps. One email that actually converts.

Install & add the widget

One click, one theme block. A “Notify me” button appears on every out-of-stock variant.

Shoppers join the line

They pick their exact size/color and drop an email. Order of signup is remembered.

You restock

Fairstock re-checks live inventory across your locations before deciding anything.

We notify — in order

Exactly as many shoppers as units, front of the line first. Everyone else keeps their place.

Why Fairstock

Three things a blast-everyone app can't do.

Fair, in-order sending

Notify exactly as many shoppers as units you restocked, oldest signup first. The people who get the email can actually buy — a restock feels like a reward, not a lottery.

Brand protection

Never a wrong alert

Live inventory is re-checked before every send. We never fire for draft, archived, always-in-stock, or already-sold-out variants — and every send and suppression is in an audit log you can read.

Reliability, provable

Flat price, not per-signup

Klaviyo bills every back-in-stock subscriber as an active profile. Fairstock is one flat monthly fee with unlimited signups — the bigger your list, the more you save.

Cost, not per-profile

Built for the way apparel sells

Sizes, colors, and drops — not generic SKUs.

  • ✓Per-variant waitlists. Someone waiting on Sand / M hears about Sand / M — never the whole product firing for one size.
  • ✓Drop-ready. Limited restocks send fairly, in order, so hype doesn't turn into 300 refund requests.
  • ✓Multi-location aware. Aggregates stock correctly across your active locations before deciding to send.

Questions

Good to know

Is this live yet?

We're building it now and onboarding a small founding cohort first. Join the list to be among the first in — at the founding price, locked for life.

How is this different from Klaviyo's back-in-stock?

Two ways. Klaviyo emails everyone at once — we notify only as many shoppers as units you restocked, in order. And Klaviyo bills every subscriber as an active profile; we're a flat fee with unlimited signups.

What does “never a wrong alert” actually mean?

We re-check live inventory before every send and refuse to fire for draft, archived, always-in-stock, untracked, or already-sold-out variants. Every decision — sent or suppressed — is logged so you can see exactly what happened and why.

Will you charge me now?

No. This page just gauges interest and pricing. We only ask for payment once you decide to install and go live.
