Par-Levels Explained in Ice Delivery Software

Par-level is one of those terms that sounds technical but describes something simple: the amount of ice you want sitting in a customer's freezer after you restock it. Get par-levels right and every freezer stays full without waste; get them wrong and you either run accounts dry or haul ice that melts before it sells. This post explains how par-levels work inside ice delivery software, how the system uses them to drive deliveries, and how to tune them over time. It follows directly from our look at Tracking Customer Freezers in Ice Delivery Software, since par-levels live on those freezer records.

What a par-level actually is

A par-level is a target quantity attached to a specific freezer. If a merchandiser holds 60 bags and you set its par at 50, you are telling the software that after every restock you want roughly 50 bags in that box. It is not the maximum the freezer can hold — that is capacity — and it is not a fixed order quantity. It is the level you top back up to. The gap between the par and whatever the driver finds on hand becomes the suggested drop for that visit.

How the software uses par-levels

Par-levels turn a route from a list of addresses into a plan with quantities. When a route is built, each stop already carries its freezers and their pars, so the platform can compute a suggested restock before the truck even loads. At the stop, the driver enters what is on hand and the app subtracts it from the par to show how many bags to drop. This is the difference between a driver guessing at a cooler and a driver executing a number the system already worked out. It also lets the office plan how much product each truck needs to carry, because the sum of the day's par gaps is roughly the day's load.

Par-levels vs standing orders

Not every account fits a par-level. Some customers want the same fixed quantity every visit regardless of what is left — a standing order. Ice delivery software supports both models side by side. A par-level account gets a variable, top-to-par drop that flexes with demand; a standing-order account gets a fixed quantity every time. Most operators use pars for accounts with unpredictable draw, like bars and event venues, and standing orders for accounts with steady, known usage. The system lets you choose per account, and even per freezer.

Setting your first par-levels

When you first set up an account, you will not have perfect data, and that is fine. Start by estimating par from what you already deliver — if you typically drop about 40 bags to keep a box full, set the par near there. The goal of the first few cycles is not precision; it is to get a working number in place so the software can start collecting real data. Par-levels are meant to be adjusted, so an educated guess on day one is exactly the right move.

Tuning par-levels from burn-rate data

This is where par-levels get powerful. Every visit records what was on hand, and over a few cycles the software learns each freezer's real burn rate — how fast it draws down between deliveries. If an account keeps arriving near empty, the par is too low for its demand and you raise it, or add a delivery day. If an account is consistently still half full, the par is too high and you are hauling ice that risks melting; you lower it. Instead of guessing, you tune each par against the actual numbers the platform has been collecting, and the freezer settles into the right level.

Seasonality and par-levels

Ice demand is deeply seasonal, and par-levels should move with it. A cooler that needs 30 bags in spring might need 60 at the peak of summer. Ice delivery software lets you raise pars heading into the hot months and pull them back down afterward, so freezers scale to demand without you rebuilding routes. Because the par drives the suggested drop, adjusting it is the single lever that ramps an account up for summer — change the number and every future delivery follows.

Par-levels and billing

Par-levels drive how much gets delivered, but billing follows the actual delivered quantity, not the par. The driver records the real drop at the stop — which may match the suggestion or override it — and the invoice is generated from that real number. This keeps par-levels honest as a planning tool while ensuring customers are billed for exactly what they received. On consignment accounts, the par sets the restock target while billing tracks what actually sold between visits.

Why par-levels beat gut feel

An experienced driver develops instincts about how much each account needs, and those instincts are valuable — but they live in one person's head and disappear the day that person is out. Par-levels move that knowledge into the software, where any driver can execute it and the office can see and tune it. The result is a system that keeps freezers full whether your best driver is on the truck or not, and that gets smarter every cycle as real burn-rate data sharpens each number.

The takeaway

Par-levels are the quiet engine of ice delivery software. They translate the physical reality of a freezer into a number the whole system can act on — suggesting drops, planning truck loads, ramping for summer, and keeping every cooler at the right level. Set them roughly at first, tune them from real data, and let the software carry the knowledge so your routes stay full and your ice stops melting on the truck.
