Inventory & Stockout Alert Report
Automatically monitor every product in your inventory against reorder thresholds each morning, then deliver a prioritised alert report so you can place orders before customers notice anything is missing.
Empty Shelves Cost More Than You Think
A customer walks in, asks for the one part they need, and you don't have it. They're not waiting. They're driving to the next shop, and there's a good chance they won't come back.
Retailers lose between 4% and 8% of annual revenue to stockouts. That's not a rounding error. For a business turning over $800,000 a year, that's $32,000 to $64,000 walking out the door. And the damage goes beyond the immediate sale: 30% to 40% of customers who hit a stockout will buy from a competitor instead.
Most businesses with 500 or more SKUs spend five to ten hours a week on manual inventory checks. Staff walk the shelves, scan screens, keep mental lists. It works until it doesn't. Seasonal demand spikes, supply chain delays, and a busy Tuesday afternoon all conspire to make manual tracking unreliable. You find out you're out of stock when a customer tells you.
Native POS alerts help, but they're blunt instruments. A fixed threshold that says "notify me at 10 units" doesn't account for the fact that you sell three of those units every day. By the time you see the alert, you've got three days of stock left and a supplier lead time of five.
How It Works
The automation runs before your doors open, checking every product against the thresholds you've set. Here's the full sequence.
1. Morning inventory pull
A scheduled trigger fires each morning (typically 6 AM) and connects to your point of sale system, whether that's Shopify, Square, or another platform. It pulls current stock levels for every tracked product across all locations.
2. Compare against reorder thresholds
Each product's stock level is checked against reorder points stored in a Google Sheets database. This sheet also holds supplier contact details, lead times, and standard order quantities. Your team can update it without touching any code.
3. Calculate days of stock remaining
Using average daily sales velocity, the system calculates how many days of stock you have left for each item. A product with 10 units and a daily run rate of 2 has five days. If your supplier takes seven days to deliver, that's already urgent.
4. Prioritise by revenue impact
Not all stockouts are equal. The automation applies ABC analysis: your top revenue items get flagged first, with the highest urgency. A bestseller at three days of stock matters more than a slow mover at the same level.
5. Deliver the morning digest
A Slack message (or email) arrives with a clean summary. Items below reorder point, items at zero stock marked urgent, and suggested order quantities. Your purchasing manager reviews it in 30 seconds instead of 30 minutes.
6. Generate purchase order drafts
For items that need immediate action, the system prefills a purchase order with supplier details, quantities, and contact information. One click to send rather than 15 minutes of looking up part numbers and supplier emails.
7. Track stockout patterns over time
A weekly summary logs which products ran low, how often, and the estimated revenue at risk. Over weeks and months, this data reveals patterns that help you adjust reorder points and negotiate better lead times with suppliers.
Why "Just Checking the Shelves" Fails
Manual checks feel reliable because they're familiar. But they fail in ways you don't see until the damage is done.
Your staff checks what they remember to check. If someone's been off sick, their section doesn't get looked at. If the shop is busy, the walkthrough gets cut short. And nobody is doing mental arithmetic about sales velocity while scanning a shelf. They see 12 units and think "that looks fine." They don't know you sold 8 of those yesterday because of a promotion that's still running.
Picture this: it's 7 AM on a Monday. You open Slack and see three items below reorder point. Brake Pad Set XR200 has two left and averages three sales a day. Oil Filter FK100 is at zero, marked urgent, with the supplier email already drafted. You place both orders before your first customer arrives. Total time: 90 seconds.
That's the difference between reactive inventory management and proactive. The automation doesn't forget, doesn't get distracted, and doesn't rely on someone noticing an empty space on the shelf.
Beyond Static Thresholds
Basic stock alerts work on a simple rule: when quantity drops below X, send a notification. That's better than nothing, but it misses the point.
A static threshold of 10 units means something completely different for a product that sells one unit a week versus one that sells five a day. The first has ten weeks of runway. The second has two days. Same alert, wildly different urgency.
Velocity based alerting solves this. By calculating days of stock remaining against each supplier's lead time, the system tells you what actually matters: will this product run out before the next delivery can arrive? If yes, it's urgent. If you've got comfortable margin, it waits.
Layering seasonal data on top makes it sharper still. If your brake pad sales typically spike 40% in November, the system adjusts projected demand to match. It recommends ordering 50% above your standard quantity to cover the surge. You don't discover the spike by running out mid month.
The Business Impact
Let's do the maths for a trades supply business with 800 SKUs and $900,000 in annual revenue.
At a conservative 5% revenue loss from stockouts, that's $45,000 a year in missed sales. Automated alerts reduce stockout incidents by 50% to 70%. Taking the midpoint (60% reduction), you recover $27,000 in annual revenue that was previously walking out the door.
On the labour side, your team currently spends roughly seven hours a week on manual stock checks. At $35 an hour, that's $245 a week or $12,740 a year. The morning digest replaces most of that effort. Even if you cut manual checks by half (your team still does a quick visual sweep), that's $6,370 saved in labour.
Combined recovery: $33,370 a year. The automation costs a fraction of that to build and maintain. And it compounds: better stockout data means better purchasing decisions, which means less dead stock tying up cash and fewer emergency orders at premium freight rates.

- Stockout incidents reduced by 50% to 70% within the first quarter
- Five to seven hours per week freed up from manual stock checking
- Purchase orders prefilled with supplier details and suggested quantities
- In stock rates above 95%, up from 80% to 85% with manual tracking
- Weekly trend data that reveals seasonal patterns and slow moving inventory
Frequently Asked Questions
Does this work with my existing POS system?
Yes. The automation connects to any POS platform with an API, including Shopify, Square, Lightspeed, and Vend. If your system can export inventory data (even as a CSV), we can build around it. Your reorder thresholds and supplier info live in a Google Sheet you control, so there's no need to change how your POS is set up.
What if I only have 50 to 100 products? Is this overkill?
Even with a small catalogue, one stockout on your bestseller costs more than a year of running this automation. And the time savings still add up. If you're spending even two hours a week checking stock levels manually, that's over 100 hours a year you could spend on higher value work.
Can it handle multiple store locations?
Absolutely. The system pulls inventory by location, so you get separate alerts for each store or warehouse. You can also set different reorder points per location if one branch moves more volume than another.
How does it handle seasonal demand changes?
The advanced version analyses sales velocity over time and factors in seasonal patterns. If a product historically sells 40% more in a particular month, the system adjusts its projections and recommends higher reorder quantities ahead of the spike. You won't get caught off guard by predictable demand surges.
Will it send too many alerts and create noise?
The ABC prioritisation means you only see what matters. High revenue items get urgent flags. Low volume products are grouped into a weekly summary rather than cluttering your daily digest. You set the sensitivity, and we tune it during setup so the alerts feel useful, not overwhelming.
What does it cost to set up?
Most inventory alert automations are built and running within one to two weeks. The exact scope depends on your POS integration and how many locations you manage. Book your free audit and we'll map out exactly what your setup looks like and what it will cost.
