Sales velocity without distortion
If your report divides sales by all 30 days — it is wrong. We exclude the days when an item was out of stock and show true sales velocity (TVelo) you can actually use to plan purchasing, analyze demand and control stock.
Dividing sales by 30 is wrong: 8 days the item was not in stock. TVelo only counts in-stock days.

your data sources
Read-only access via the Shopify API or Google Sheets. Every source = a separate warehouse.
Not a spreadsheet. A command center.

Doing well — a few growth points left.
Six things that save you money
Every number is backed by methodology and a data-confidence score.
TVelo — true sales velocity
Calculates sales velocity excluding the days an item was out of stock. The real picture: which items sell fast and which turn into dead stock. The difference vs the naive formula can reach 50%.
Days of cover
How long your stock will last. A signal in advance — not after the item is already gone.
Lost revenue
How much revenue you lose while an item is out of stock.
Purchase planning
Calculations based on true sales velocity and supplier lead time.
Frozen stock
How much money is frozen in slow-moving SKUs.
Data confidence
We score how trustworthy the data behind each decision is.

Excel vs Veloseller
What changes when you stop counting by hand
Excel spreadsheet
- You compute sales velocity by hand once a month
- Out-of-stock days are ignored — your numbers are distorted
- No idea how much money is stuck in dead stock
- Alarms arrive after the fact, when it is already too late
Veloseller
- We exclude out-of-stock days — true sales velocity
- Reorder signal 7–14 days before you run out
- Telegram + email reports every morning

Sellers on the numbers they saw for the first time
Finally stopped computing sales velocity in Excel. Within a week I saw 12% of my working capital frozen in dead stock — cut a couple of reorders and freed up $4k.
TVelo showed that half of my 'slow' items were actually fast — they just kept going out of stock. Reordered them — revenue +18% in a month.
Telegram alerts are the killer feature. I do not sit in dashboards. A signal comes in, I reorder, done.
