A late supplier changes more than your stock level. It changes whether and when you should buy from that supplier again. When an order is overdue, or a supplier has a habit of slipping, the question before the next purchase order is not only whether you are low, but whether you can count on that supplier to deliver in time, and what you change if you cannot. After Stocky, Shopify does not flag late suppliers for you. The purchase order records an estimated arrival date you set when you place it, and the date passing is a signal you read, not an alert the platform sends. Stocky will not be available after August 31, 2026, and from that date you manage inventory in the Shopify admin and Shopify POS, so reviewing a supplier’s recent timing and your buy list before you reorder is a habit you now run yourself. Here is what to check before you buy again from a supplier who has been late.
Why a late supplier changes the next purchase-order decision
A late delivery is not just an inconvenience; it is information about the supplier you are about to order from again. Shopify’s own supplier guidance suggests comparing suppliers on factors such as reliability, product quality, delivery times, and cost, and delivery time is the factor a late order puts under the spotlight. A supplier who slipped once might still be the right choice with a bigger buffer. A supplier who slips often changes the math on both timing and quantity: you order earlier, hold more cover, or look at an alternative. The order itself gives you the timing record to reason from, since a Shopify purchase order tracks the products, costs, payment terms, and an estimated arrival date you set when you place it. The wider decision of what to reorder and when sits in reorder planning after Stocky; a late supplier is the input that pushes its timing. How lead time feeds that timing in the first place is covered in supplier lead time in reorder planning.
Start with the buy list, not a new purchase order
The reflex when an order is late is to place another one. Slow down and put the decision on the buy list first, where you can group items by supplier, settle quantities, and decide who to order from before anything is committed. In Shopify, suppliers are created in the admin when you create a purchase order, and the order records the decision once you make it: a Shopify purchase order records the products, their costs, and the quantities ordered from a supplier. Keeping the deciding on the buy list is what stops a late order from triggering a rushed duplicate. The supplier-ready buy list groups the round by supplier, the buy list after Stocky holds the reviewed decision, and running it on a fixed cadence is the weekly reorder list habit. One limit shapes the handoff: purchase order APIs aren’t currently available in Shopify and are under consideration, so an outside tool cannot open the order for you, and the review stays a step you run by hand before the order screen.
Check the supplier’s lead time against how soon you need stock
A late order is most useful read against two numbers: how long this supplier usually takes, and how soon you actually need the stock. The first comes from your own record of past orders, the gap between the estimated arrival date you set and when the goods actually arrived, kept across several orders rather than judged from the latest one. The second is the days of cover on the item, how long current stock lasts at recent sales. When the supplier’s typical timing is longer than your cover, you are already exposed, and a late order only confirms it. Treating that timing as a real per-supplier number is the subject of supplier lead time in reorder planning, and reading it alongside the other reliability signals is what supplier performance metrics pulls together. The point of checking both before you reorder is that a slow supplier and a fast-selling product is the combination that turns a late order into a stockout.
Review the open order and what still needs follow-up
While the late order is still out, it needs a follow-up, not a replacement. A purchase order whose estimated arrival date has already passed is overdue, and the order record is where you check what you expected against the calendar. The useful move is to contact the supplier, get a revised date, and write down what you learn, because Shopify’s supplier guidance recommends keeping notes and documentation on each supplier relationship and a late delivery is exactly the kind of context you will not remember next quarter. Opening a second order for the same items while the first is in flight risks double-buying, so confirm where the open order stands before you commit to anything new. The history these notes build up is also what you would export before the cutoff, since historical Stocky data, including old purchase orders and stocktakes, will not move into Shopify automatically after the shutdown.
Separate a slow supplier from a slow product
A late order is a reason to look at the supplier, not an automatic reason to reorder the item. Supplier reliability measures the supplier: whether they deliver complete and on the date agreed. Product demand measures the item: whether it is selling fast enough to be worth restocking at all. These are different questions from different data. Shopify’s inventory reports summarize past sales and current stock to help you decide which products to prioritize when restocking, and they are not automatic reorder recommendations and do not calculate reorder quantities, so the demand side comes from your sales history, not from the supplier’s delivery record. The trap to avoid is chasing a late supplier on a product that is barely moving: the right call there is often to let the slow item go, not to fight for a faster delivery. The running view of what is actually worth restocking sits in the weekly reorder list.
Hold, split, or change the next order
Once you know the supplier was late and the product is worth restocking, the late delivery shapes what you do next. If the supplier slipped once but is usually steady, the simplest fix is to order earlier and hold a slightly larger buffer next time. If lateness is becoming a pattern, splitting the order across a second supplier, or holding a small safety order with a faster one, spreads the timing risk. If a supplier is reliably late and the product matters, it may be time to change who you buy it from. None of these is a calculation Shopify runs; they are judgement calls you make from the supplier’s record, and the cleaner that record, the easier the call. Building that record so a one-off slip is easy to tell from a pattern is supplier lead time tracking. Turning a run of late orders into a per-supplier read you can act on is the monthly habit behind tracking supplier performance after Stocky. When you do reorder, the decision lands in a native Shopify purchase order, which records what you settled on rather than the deciding itself, the working-list-versus-record split set out in CSV vs PDF purchase orders.
Late supplier review checklist
Before you reorder from a supplier who has been late, run the same short check. First, the open order: is its estimated arrival date already past, and have you asked the supplier for a revised one. Second, the supplier’s typical lead time, read from past orders rather than the latest slip. Third, the days of cover on the item, so you know how exposed you are right now. Fourth, demand: is the product still selling, or is a late delivery a reason to stop ordering it. Fifth, a written note of what happened and whether this supplier has slipped before, so the pattern is on record. Sixth, the decision: order earlier, hold a bigger buffer, split across suppliers, or change supplier. Seventh, only then move the item onto the buy list and, once reviewed, into a purchase order. Running the checks in order is what keeps a single late delivery from turning into a rushed or duplicated buy.

Limitations
Reviewing a late supplier before you buy again is a planning habit, not a Shopify feature, and this guide does not cover every workflow Stocky used to support. Shopify does not flag late suppliers or score them for you; it records the orders you read the timing from. It does not create Shopify purchase orders; those stay native to the Shopify admin. None of this is demand forecasting, and the calls you make about a supplier are judgement calls a person reviews, not numbers to follow blindly. It does not promise better supplier performance, fewer stockouts, or less dead stock, and it is not legal, accounting, tax, or financial advice. Supplier scorecards should be built from supported supplier, vendor, and order records you actually hold, never from fake reviews or synthetic testimonials. Shopify purchase orders, supplier and vendor records, inventory records, and supplier reliability notes still need source-backed checks against your own store. For the slice where turning that order history into a per-supplier read is the heart of the work, the existing kijun app is one option, scoped honestly: it builds 0-100 supplier scorecards from purchase orders recorded in kijun, on supported supplier and vendor records, and it does not forecast demand or reorder for you.
