Par Levels: How Much Stock a Café Should Actually Hold
1 September 2026 · MidaOne
Most cafés fail at stock in one of two directions, and usually both in the same week. On Saturday you run out of oat milk at eleven in the morning and spend the rest of the day apologising. On Tuesday you pour four litres of full-fat down the sink because you over-ordered after Saturday. Neither is a discipline problem. It is what happens when ordering is done from memory and mild anxiety instead of from a number, and the number that fixes it is a par level.
What a par level actually is
A par level is the quantity of an item you want to have on hand at the moment you place an order — enough to keep serving until the next delivery arrives, plus a small cushion. It is not a maximum, and it is not how much you order. You order the difference between the par and what is on the shelf.
The value of it is that it turns a judgement call into subtraction. Whoever is on shift counts what is there, subtracts from the par, and orders the gap. That is a task a new starter can do correctly in their second week, which is the actual point: ordering stops being something only you can do.
Set the par from usage, not from instinct
The starting number is your average daily usage of the item. Not what you think you use — what the till says you sold, multiplied by how much of the item goes into each thing you sold. If a flat white takes a fixed amount of milk and you sold 180 of them last week, your milk usage is not a guess, it is a calculation you can do in a minute from a sales-by-item report.
Two adjustments matter. First, use a recent period rather than a full year, because a café's mix drifts and a par set on last winter's iced-drink sales is wrong by September. Second, use the busy day, not the average day, for anything you cannot get delivered quickly. An average that blends a quiet Monday with a heavy Saturday sets a par that fails you on precisely the day it matters.
If you do not yet have per-item quantities written down, this is the step that unlocks everything else, and it is the same work as costing your recipes. Do it once for your top twenty items and you will have covered most of what you buy.
Lead time is the number everyone forgets
A par level is meaningless without the delivery schedule attached to it. What you actually need to cover is the gap between placing an order and being able to place the next one — the supplier's lead time plus your own ordering cycle. A dairy supplier who delivers on Monday, Wednesday and Saturday means you need to hold enough to get from one delivery to the next, not enough for a week.
In practice the working shape is: par = average daily usage × (days until the next delivery lands) + safety stock. The second half of that is the part worth thinking about rather than copying.
It is also worth being honest about which of your suppliers actually hit their stated schedule. A delivery window that slips by a day twice a month is a real lead time of one day longer than the invoice says, and your par should reflect the supplier you have rather than the one you were promised. Managing suppliers and delivery days is where that conversation belongs — but until it changes, set the par for reality.
Safety stock: how much cushion, and for what
Safety stock covers two things: demand you did not predict, and deliveries that did not arrive. How much you hold should depend on what happens if you run out and how quickly the item goes off.
| Item type | How to set the cushion |
|---|---|
| Sells constantly, spoils fast (milk, fresh pastry) | Small cushion, more frequent deliveries — a stockout costs a sale, but so does a bin |
| Sells constantly, keeps well (beans, cups, syrups) | Generous cushion; the only cost of holding it is shelf space and cash |
| Sells occasionally, keeps well (specialty tea, packaging) | Order rarely in larger quantities and set a low reorder point |
| Sells occasionally, spoils fast (a slow cake, a garnish) | Hold almost nothing and question whether the item earns its place at all |
That last row is the one worth acting on. An item that has to be held fresh and does not sell is a recurring waste line pretending to be a menu choice. Your waste log will tell you which items those are faster than your instinct will — keeping a waste log that is actually used is the fastest way to find them.
Different pars for different weeks
A single par per item is better than nothing, but a café's week is not flat. If Friday and Saturday are two-thirds of your milk consumption, one par set on a weekly average will have you short on Thursday's order and long on Sunday's. Set a weekday par and a weekend par for your top few movers — it is a small amount of extra work on maybe eight items, and it is where most of the benefit lives.
Pars also need a review date, or they quietly become fiction. Once a quarter, and after anything that changes the trade — a menu change, a new competitor opening nearby, a school term starting, Ramadan, the summer — pull the usage figures again and reset. Trade in the UAE moves enough through the year that a par set in February is describing a café that no longer exists in July.
What good looks like after a month
You will know the pars are right when three things are true: you are not sending someone to the supermarket mid-shift, your waste on fresh items is falling rather than your stockouts rising, and the person doing the order is not you. If waste is down but you are running out more often, the cushion is too thin. If neither is moving, the pars are probably set above what you were already holding and nothing has actually changed.
Getting there is also the cheapest margin improvement available to most cafés, because it costs nothing but attention. What it recovers shows up in food cost percentage within a couple of months.
Where MidaOne fits
Par levels need two numbers you should not be counting by hand: what you sold and what that consumed. MidaOne tracks stock live as you sell, so the shelf figure you subtract from the par is already there rather than reconstructed on a Sunday. Sales by item and by day give you the usage a par is built from, waste by item shows which cushions are too generous, and the marketplace lets you order from suppliers inside the same system rather than across three WhatsApp threads. The counting side of all this is covered in café inventory management.

What is a par level in a restaurant?
It is the quantity of an item you want on hand when you place an order — enough to last until the next delivery arrives, plus a cushion for surprises. You order the difference between the par and what is actually on the shelf, which turns ordering into subtraction instead of judgement.
How do I calculate par levels for a café?
Start with average daily usage taken from what you sold and how much of the item each sale consumes. Multiply that by the number of days until the next delivery can land, then add safety stock sized to how badly a stockout would hurt and how quickly the item spoils.
How often should par levels be reviewed?
At least quarterly, and any time the trade changes — a menu update, a seasonal shift, Ramadan, a new neighbour taking your footfall. Pars set on old usage quietly stop matching the café, and the symptom is usually rising waste on one item and stockouts on another.
Should par levels be different for weekends?
For your fastest movers, yes. If two days carry most of your volume, a single weekly average leaves you short before the weekend and overstocked after it. Setting a weekday and a weekend par on your top handful of items captures most of the benefit for very little extra work.
What is the difference between a par level and safety stock?
Safety stock is a component of the par, not an alternative to it. The par covers expected usage until the next delivery; safety stock is the extra held on top to absorb a busier day than forecast or a delivery that arrives late.
Pars are unglamorous enough that plenty of cafés never set them, which is precisely why setting them separates a café that is managed from one that is merely watched closely. Spend an hour with your sales-by-item report and your delivery schedule, write a number next to your twenty most important items, and stick the list where the order is placed. The first week will feel like admin. By the third, someone else will be doing the ordering and getting it right.
