Hurricane Season Inventory: How Many Days a Houston Boba Shop Should Carry

Almost every article about boba shop inventory is written as though the only risk is ordering too much. In Houston that advice is incomplete in a way that can close your doors. From June through November, the Gulf adds a variable no other major US boba metro has to plan around: a storm system that shuts down freeways, warehouses and delivery routes for several consecutive days. The supply base itself is strong — Houston shops rarely need to buy out of state — but strong local supply does not help when nothing is moving. This is the arithmetic on how deep your buffer should actually run, and which handful of items decide it.

Why Houston is a different inventory problem

Houston's wholesale base sits largely in the southwest quadrant, concentrated around the Asiatown stretch of Bellaire Boulevard, and most suppliers run their own delivery trucks into the metro rather than shipping parcel. That is normally an advantage. Route delivery is cheaper than freight, lead times are short, and a shop that misses a cut-off can often sort it out with a phone call.

The same structure is what makes storm weeks bite. A supplier running their own trucks is a supplier whose deliveries stop entirely when the roads are underwater — there is no parcel carrier quietly continuing in the background. And because the base mixes boba-native specialists with broadline Asian food distributors, a lot of Houston shops split their ordering across two or three accounts by category. Splitting is sound practice, but it means a storm week can interrupt several separate delivery schedules at once, each with its own recovery backlog.

The recovery is the part owners underestimate. The closure itself might be two days. Warehouses then reopen with a queue of orders that accumulated while they were shut, and route schedules rebuild over the following days. A two-day weather event routinely becomes a four- or five-day gap between the order you expected and the pallet that actually arrives.

Work out your real daily burn first

Safety stock is meaningless as a general instruction. "Keep extra pearls" tells you nothing about how many kilograms. The calculation has to start from how much you actually consume in a day, and most shops have never written it down.

Take tapioca pearls as the worked example. A shop selling 200 drinks a day, with roughly 70% of those containing pearls, is serving about 140 portions. At a typical 30 g dry weight per portion, that is 4.2 kg of dry pearls a day. Pearls commonly arrive in 3 kg bags, six to a case, so a full case of 18 kg is a little over four days of service at that volume.

That single number reframes the whole question. A Houston shop at 200 drinks a day holding one spare case of pearls does not have a comfortable cushion — it has roughly the length of one storm disruption, with nothing left over. Hold two cases and you are at eight or nine days, which comfortably covers the closure plus the backlog.

Run the same arithmetic across your list and the picture gets clearer fast. At 200 drinks a day you are using around 200 cups, lids and straws daily; a sleeve-based cup case in the 500–1,000 range is two to five days. Fructose syrup at roughly 25–30 g per drink is about 5–6 kg a day, so a single large jug is well under a week. Powders and tea concentrates usually stretch further per unit, which is exactly why they are rarely the item that closes you.

Only about six items actually decide whether you open

This is the part that keeps the cost sane. You do not need a storm buffer on your entire catalog, and trying to build one is how shops end up with expired inventory and a cash flow problem in March.

Sort your list by one question: if this ran out tomorrow, would I stop selling, or would I sell a slightly different menu?

For most shops, the genuine close-the-doors list is short — pearls, cups, lids, straws, sealing film, and your single highest-volume sweetener. Run out of any one of those and service stops. Everything else, including most flavour powders, jellies, popping boba and specialty teas, degrades your menu without ending it. A week without lychee jelly is a week of apologies. A week without lids is a week of closure.

Sealing film deserves a specific mention because it is the item shops most often forget. It is cheap, it is consumed invisibly, it is easy to assume you have plenty of, and there is no workaround — a sealing machine with no film is a shop that cannot serve a sealed drink. It belongs on the short list, and it is the least painful item on that list to over-buy.

What the deeper buffer actually costs

Here is where most hurricane advice stops being useful, because it never puts a number on the trade-off. Let us put one on it.

Take that same 200-drinks-a-day shop and assume it wants to move from roughly four days of cover to roughly nine on the six critical items only. In practice that means carrying one additional case of pearls, one additional case of cups with matching lids and straws, one extra roll or box of sealing film, and one extra jug of your main sweetener.

Depending on your supplier and current pricing, that additional block of stock is commonly in the region of a few hundred dollars — the kind of number that fits inside a single ordinary weekly order rather than requiring a special purchase. It is bought once and then simply maintained, because you rotate through it in normal service anyway.

Now price the alternative. A shop turning over $200 a day in gross profit that closes for three days has lost $600 in margin, and that is the visible part. The invisible part is worse: staff scheduled and either paid or sent home, a queue of regulars who went somewhere else and discovered it was fine, and delivery-platform rankings that punish a closed storefront. Against that, a few hundred dollars of dry goods that you were going to buy eventually anyway is not a close decision.

The honest caveat is that this only works on shelf-stable goods. Do not extend the same logic to dairy, fresh fruit or anything else with a short life — there the correct storm plan is a shorter menu, not a bigger fridge.

A decision rule you can actually follow

Storm forecasting gives you more notice than most supply disruptions ever do, which makes this one of the few inventory risks you can genuinely act on in advance. A simple rule works better than good intentions:

From June through November, keep the six critical items at nine days of cover as your standing baseline. That is roughly double a normal week, and it is low enough that you rotate through it without waste.

When a named system enters the Gulf with any Texas coast projection, place your next order immediately rather than on your normal day — and place it before the forecast tightens, not after. Warehouses along Bellaire receive the same forecast you do. The shops that order on day one get filled from stock; the shops that wait until the track is confirmed are competing for the same pallets with every other shop in the metro, and some of those orders will not be filled before the roads close.

Then, when the system passes, expect your first post-storm delivery to be late and partial. Plan the following week around a short menu rather than assuming normal service resumes the moment the sun returns. Ring your suppliers before their route day instead of waiting for a truck — the shops near the front of the recovery queue are the ones who called.

The part that has nothing to do with weather

Working through this exercise has a side effect worth more than the storm preparation itself: you end up knowing your daily burn rate on the items that matter, and most shops genuinely do not. Once you know that pearls are 4.2 kg a day and a case is four days, you stop ordering by instinct on every other item too. Your par levels become numbers instead of feelings, and the ordinary Saturday shortages — the ones that have nothing to do with hurricanes — start disappearing as well.

That is the quiet argument for doing this properly. Houston's storm season simply forces a discipline that every shop benefits from, and the shops that build it in June tend to find they order better all year.
