The booking floor
Fixed-slot capacity, guaranteed at the database
Every pencilled or confirmed slot rides the same fixed-slot / identity-keyed capacity decision the schedule.software family is built on: no-double-book and per-slot capacity are both enforced at the database, not in application code that can race. This is the floor every state below -- pencilled, held, confirmed -- sits on top of.

The one edge no incumbent ships
A pencilled slot is a real third state, not a countdown bolted on top
Booked-or-nothing is a modeling choice, not a law of scheduling. The design: a pencilled slot is a third state distinct from both "open" and "booked" -- it counts against capacity (so it cannot double-book), it is visibly provisional to everyone who can see it, and it carries its own expiry. It belongs where the booking decision is made, not as a countdown drawn on top of an ordinary booking. To be plain about status: this state is not built today. The fixed-slot floor it is designed to sit on is; the hold state itself is the thesis of this product and the thing being built next. Nothing on penciled.software serves a real hold yet.

What happens if nobody acts
Auto-expiry releases the slot back, on its own, without a support ticket
A pencilled hold is designed to carry an expiry the holder sees up front. If nobody confirms before it lapses, the slot releases back to open capacity automatically -- no admin has to notice a stale hold and manually clear it, and no client is left wondering whether an unconfirmed hold is still theirs. Auto-release is the design; it is part of the same unbuilt hold lifecycle above, and no expiry is running anywhere today.

The other way out
One tap turns a pencil mark into ink
The other resolution to a pencilled hold: the holder confirms before it lapses, in one action, and the slot moves from provisional to booked without re-entering anything they already told the system when they pencilled it in. Designed, not built -- the same unbuilt lifecycle as the two above.

When a hold lapses anyway
Smart reschedule: the same proposer the fleet already runs in production, pointed at a lapsed hold
The scheduling platform this family shares an engine with describes a self-healing reschedule proposer of its own: a ranked list of minimal-cascade changes when a disruption hits a schedule, with a human ratifying before anything commits, built for that platform's dispatch booking law. That is its account of its own engine, not a measurement taken here. "Smart reschedule" is the design intent to point that same proposer at a lapsed or declined pencil hold: instead of a dead end, the holder sees a short ranked list of nearby open slots. That specific application is planned, not yet wired -- this page does not claim it runs today.

The thing every incumbent paywalls
A custom domain, free -- not an enterprise upsell
A booking page at your own hostname, not a shared subdomain, is planned on every tier including the free one -- the same inversion the rest of this platform's family plans: the appointment-link tools you already know make you climb to a paid, often enterprise, tier just to put your own name on the page. This is a packaging and pricing plan, not a claim that the connect-your-domain flow is live: pricing on this page is display-only.

The one step up from your own domain
White-label branding lives at the first paid tier, not the last one
Your logo, your colors, and the small badge gone -- planned for the Pro tier, the tier a solo practitioner or small studio actually buys, instead of gated behind an Enterprise sales call the way several tools in this category structure it. Team adds org-wide brand inheritance across every seat on top of that, not a separate branding tier. None of this is built on penciled.software yet -- it is a packaging plan, not a claim that a branding surface is live; pricing shown is display-only.

One note on the category, since this page makes a claim about it: the appointment-link, sign-up-sheet, and group-poll tools this product is measured against are referred to here by category only, never by name. The “booked or nothing” framing above is our reading of how these tools model a slot as of this writing, not a tested claim about any one of them, and any of them may ship a hold state tomorrow. No competitor brand is named on this site.
