“Selling about 5 a day. New stock takes 14 days and you keep a 4-day buffer, so you need about 90 to last until it lands. You have 50 and none on order, so you're 40 short.”

Who it's for
Built for Shopify stores that buy their own stock
You run a Shopify store, buy stock from a handful of suppliers and make the reorder decisions yourself, often from a spreadsheet, a stock export or gut feel. Fillova is built for that job. It works like a careful purchasing colleague: it checks the numbers, tells you what needs ordering and explains its reasoning. Then you decide. See reorder planning for Shopify.
What it does
What Fillova does for you
Keep best-sellers in stock
Fillova compares how fast each product is selling with how long your supplier takes to deliver, so you can see a reorder coming before the shelf is empty.
Keep cash off the shelves
Every quantity is sized to your lead time and safety buffer, minus what you already have and what's on the way, so you stop ordering “a few extra to be safe”.
Know why, every time
Each recommendation comes with a short explanation: how fast it's selling, how long new stock takes and what's already coming. You can check the number before you spend money on it.
Never order the same stock twice
Record an order and Fillova counts that stock as on its way. When the delivery arrives, record it, and correct it if the delivery was short or wrong.
Fillova is designed to help with all four. It hasn't launched yet, so these are aims, not measured results.
How it works
How a recommendation is worked out
- 1
Fillova reads your Shopify store
It syncs your products, variants, stock levels and locations, and imports your recent orders. There's nothing to upload.
- 2
You set your suppliers' lead times
Set a lead time for each supplier, and override it for an individual variant if one takes longer. Fillova starts with a 4-day safety buffer you can change.
- 3
Fillova works out what's needed
It estimates how fast each product sells from the last 30 days, giving more weight to the most recent 7, so a recent trend counts without one odd week taking over. A one-off spike is handled so it doesn't inflate your order. It then applies your lead time, buffer, stock on hand and stock already on order.
- 4
You decide, Fillova keeps count
You see the products that need a decision, each with a recommended quantity and its reason. You place the order with your supplier as you do today, record it in Fillova as a purchase order, and record what arrives.

FAQ
Questions merchants ask
What does Fillova actually tell me?
Which products need reordering, how many to order and why, based on your sales, your suppliers' lead times, your safety buffer and the stock you already have or have on order.
Do I have to open Fillova for it to update?
Each time you open Fillova, it works from your latest Shopify sales and stock. It doesn't send alerts.
How is this different from a low-stock alert?
An alert tells you something is low. Fillova tells you how many to order, takes your supplier's lead time and the stock already on the way into account, and shows its working.
I relied on Stocky's reorder suggestions. Is Fillova for me?
If what you miss is knowing what to reorder and how many, yes. Fillova focuses on reorder decisions; it doesn't do stocktakes, labels or POS.
How much will it cost?
Pricing will be announced before launch. Joining the early-access list is free and doesn't commit you to anything.
Does Fillova use AI?
Fillova uses a clear calculation based on your sales, stock, lead times and buffer, and shows the reasoning behind every recommendation, so you can check any number yourself.
