Two different tools, and most people need theirs.
Stockroom, by MyWorks, is free and rebuilds the Stocky workflow. Days of Cover is a forecast that ranks by profit and shows its working. This page is for deciding which of those you are short of, including the common case where the answer is not us.
They are a purchasing system. We are a decision tool. Stockroom answers "which products crossed a line I set". Days of Cover answers "you will run out of this in six days, order forty, and here is the arithmetic". If you have no way to raise a purchase order at all, that is the more urgent gap and it is not the one we fill.
Pick by what is missing.
Which one are you short of?
Install Stockroom
- You need receiving, and you need stock to move when an order arrives
- You do stocktakes, adjustments, or transfers between locations
- You have more than one location
- You print barcodes or price labels
- You use Shopify POS, Shopify Flow, QuickBooks or Xero
- You just need somewhere to raise and track purchase orders, free
Install Days of Cover
- You can already raise a purchase order. You cannot decide what goes on it
- Your money runs out before your reorder list does
- Your biggest seller and your most profitable product are not the same product
- You want to know what last month's stockouts actually cost you
- You do not trust a suggested number you cannot take apart
- One location, physical goods, and cash is the binding constraint
Running both is a normal answer and we would rather say so than pretend the overlap is bigger than it is. We are read-only on your store: we never write a quantity, so we cannot collide with a purchasing tool that does.
Where the models differ.
A threshold you set, or a forecast that explains itself
This is the whole difference, and it is worth understanding before picking, because it decides what each tool can and cannot tell you.
- Stockroom: three thresholds per productIt reads recent sales and suggests a low-stock level, a reorder point and a max. You press Apply and they become your values. Anything at or below its reorder point appears on a list, grouped by supplier, ready to become a draft order. It is a min/max system, and min/max systems are proven and understood.
- Days of Cover: a rate, and what follows from itWe work out units per day per variant, exclude days you were out of stock only when there is evidence you were, and derive days of cover, a reorder point and a suggested quantity from it. Every tracked variant gets forecast the night you install, with nothing to configure first.
- What a threshold cannot tell youThat this product earns four times what that one does. Or which eight of your twelve urgent items your cash actually covers. A line does not rank the things that cross it.
- What a forecast cannot tell youAnything about stock it cannot see moving. If your problem is that stock arrives and nobody records it, a forecast built on your Shopify quantities inherits that error. Fix the recording first, with their tool or another.
Stated plainly, because you will find it anyway.
What they have that we do not
Receiving. Stocktakes. Inventory adjustments with an audit trail. Transfers between locations. Barcode and price label printing. Shopify POS. Shopify Flow triggers. QuickBooks and Xero sync. Landed costs. Dead stock reports. Multi-location purchase orders. Pack sizes.
Every one of those is deliberately outside what this app is for, not a gap we are working towards. And theirs is free, with no paid tier at all, so none of it is a price argument either.
Export everything before 31 August whichever way you go. Stockroom advertises a one-step import of Stocky suppliers and purchase order history; that is their description of it and we have not run it, so go and see for yourself rather than take either of our words for it. Days of Cover reads the same export for costs, lead times, open orders and stock history, and reports per row anything that would not match. And here as there, marking a purchase order received does not change your Shopify inventory, which is the Stocky habit worth unlearning early.
