Unbusy Labs
For Amazon FBA brands with their own warehouse
Your reorder plan updates itself. Every morning.
A Google Sheet in your own account. It pulls stock and sales from your inventory system, Amazon FBA and open purchase orders, then shows how many units of each SKU to order from your manufacturer.

Sound familiar?
Once a week someone rebuilds the reorder sheet by hand. By the next morning it’s out of date.
Your warehouse, Amazon FBA and open orders each show a different number, so someone reconciles them by hand.
You notice a SKU is running low when the next batch from the factory is still weeks away.
A stockout on Amazon costs sales and ranking. Ordering too much locks cash in boxes. A plan that updates itself every morning helps you avoid both.
Example
From a hand-built Excel sheet to a plan that updates itself
An e-commerce brand selling on Amazon and other marketplaces. Client name not disclosed.
Before
Reorders were calculated by hand in Excel.
Warehouse stock, FBA stock and open purchase orders lived in different places.
Sellerboard needed warehouse stock, but there was no API to send it there.
What I built
A daily reorder plan in Google Sheets. Data comes from the brand’s inventory system, connected directly via its API, and from Amazon FBA and open purchase orders.
Stock movements through two folders, “To FBA” and “Arrived”. Drop a file in, and warehouse stock updates, with every change logged.
A Sellerboard file with warehouse stock already filled in, ready to upload.
What changed
Every morning there’s a ready answer to what to reorder and how much, instead of a manual calculation.
Warehouse stock, FBA and stock already on order sit in one sheet.
Every stock change is logged and can be checked.

SKUs in the plan
sources in one sheet: inventory system, Amazon FBA, purchase orders
plan ready every morning
from contract to acceptance
of Make.com’s cheapest paid plan is all it uses
From first message to handover: about two weeks. Contract to acceptance: 9 days. Entirely in writing.
Pilot scope
What the pilot covers
Included
One warehouse or one country
2–3 data sources
A reorder plan sheet with settings you control: days of stock, production lead time, seasonality, minimum order quantity
Error alerts by email
Instructions inside the sheet itself
Everything runs in your own accounts. You’ll need a Make.com account (paid plan, billed to you by Make; the Core plan was enough for 283 SKUs), a Google account and API access or file exports from your inventory system.
Not included
Automatic purchase orders to your manufacturer
FBA shipment recommendations
Telegram or Slack alerts
Amazon AWD stock
After the pilot: stock updates through shared folders, and ready-to-upload files for services without an API.
Fixed price, agreed in writing after the brief.
How it works
Four steps, all in writing
01
Written brief
You describe your stock, sales channels and how you reorder today. I reply with follow-up questions.
02
Fixed scope and price
I send what’s included, what isn’t, and the price. Work starts once you agree.
03
Built on your real data
I build the plan in your own Make.com and Google accounts, using your real data.
04
Handover
You get the working plan with instructions inside the sheet. It stays yours. If anything breaks in the first 14 days, I fix it at no cost.
No calls. Everything happens in writing, so it works in any time zone and every decision is on record.
Questions before you write
How is this different from Amazon’s restock recommendations?
Amazon’s Restock tool suggests how many units to send to FBA. This plan answers the step before: how many to order from your manufacturer, counting your own warehouse, FBA stock including shipments on the way, and orders already placed. The formula is in your sheet, so you can check every number.
What does it cost to run?
Your Make.com plan, billed to you by Make. For 283 SKUs the cheapest paid plan was enough, with about two thirds left unused.
My system has no API. Can it still work?
Often yes. If it can export a file, the plan can read it from a shared folder. I check this in the brief, before the price.
Who can see my data?
Everything runs in your own Make.com and Google accounts. I work there with the access you give me, and you can remove it after handover. You connect Amazon yourself through its official authorization: I never see your Seller Central password, and the plan only reads stock levels.
Do we need a call?
No. Brief, scope, price and handover all happen in writing, so you reply when it suits your time zone.
Request a pilot
You’ll work directly with me, Vitalii. I automate business processes with Make.com, APIs and Google Sheets. Tell me a little about your store, and I’ll reply by email.
