For party and event rental shops

Never promise the same 200 chairs twice.

Tentpole counts every table, chair, tent and linen you own by the day, stops an order that would overbook, and prints your drivers' sheets in the morning.

Open Tentpole Watch it catch a double booking

Free. Works in your browser. No sign-up, nothing to install.

The first sign of an overbooking is a driver standing in an empty warehouse.

Two weddings, one Saturday, 200 chairs. On a whiteboard nobody does the subtraction until the truck is half loaded. Tentpole does it the moment you type the order.

The overbooking check

One Saturday. Four orders. 200 chairs.

  1. Step 1 · Book the Hendersons.

    The Henderson wedding wants 120 white folding chairs for June 6. Tentpole checks every day of the rental, delivery to pickup. 80 left.

  2. Step 2 · Add the Parks.

    A backyard graduation for the Parks needs 50. Still fine, but the day is getting tight: under 20% of your chairs are left, so the calendar turns it amber.

  3. Step 3 · Fill it with the Ortiz party.

    The Ortiz 50th takes the last 30. Exactly zero left is allowed. The day goes blue: full, not over.

  4. Step 4 · Try one more.

    Then the church picnic calls and wants 80. Tentpole names the item, how many you need, how many are free and the date, and the Save button stays off until you fix it.

    Same rule on the pickup day. Chairs still on the truck are still booked.

How it works

Three things, every day.

  1. Count what you own.

    Add each item once with how many you have: 200 white folding chairs, 2 frame tents, 40 round tablecloths. Or load the sample inventory and try it in a minute.

  2. Book by the day.

    Enter the customer, the address, the delivery and pickup dates, and the items. Each line shows how many are free for those dates before you save.

  3. Print the morning.

    Pick a date and get the delivery sheet or the pickup sheet: stops in time order, a load list for the truck, and a signature line for every stop.

What's in it

Built for the weekend rush.

See free stock for any item, any day.

Pick "Chiavari chair" and the month fills with how many are free each day, coloured ok, low, full or over. "Do you have 150 chairs any weekend in June?" takes one glance.

Conflicts that say exactly what's wrong.

One message per item: what you asked for, the most that's free, and every date it fails on.

The whole day in one panel.

Click a date to see owned, reserved and free for every item, plus who is getting a delivery and who is being picked up.

Sheets your drivers can use.

Stops sorted by time, untimed stops last. Phone, address, items, notes and a signature line on each. A stop never splits across pages.

Edit without false alarms.

Changing an order never counts against itself, so bumping 120 chairs to 130 only checks the 10 extra.

Stays on your computer.

Everything is saved in your browser as you go. No account, no server, no monthly fee. Export a backup file whenever you like and import it on another computer.

Works on the phone in the yard.

Bottom tabs and a stacked day panel on a phone. Light or dark, it follows your system.

Delivery and pickup sheets

Hand the driver a page, not a phone.

Every morning, pick the date and press Print. The app's navigation disappears and you get a clean sheet: a load list totalling every item on the truck, then each stop in time order with the phone number, the address, what goes where, any notes, and a line to sign.

A printed delivery sheet for Saturday, June 6, 2026, with a load list and two stops: the Henderson wedding at 8:00 and the Park graduation at 9:30, each with a signature line.

The real app

This is Tentpole. Go ahead and use it.

Below is the actual app, running right here. Press "Load sample inventory", add an order for a Saturday, then try to book more chairs than you have.

Anything you add stays in this browser, so it will still be there when you open the full app.
