most DTC brands bleed cash from bad inventory forecasting.
either you stock out and lose sales, or you overstock and kill your cash flow.
here’s how to build a simple AI forecasting agent that gets it right.

1 / ingest the data
you can’t forecast what you don’t track. set up your data flow:
– connect Shopify to Google Sheets via n8n (or your tool of choice)
– pull daily order data for your top 20 SKUs over the last 180 days
– capture these columns:
Date
sku
units sold
discount %
promo flag (1/0 to mark sale periods)
bonus: tag any product launches or influencer pushes. that context improves accuracy later.

2 / build the brain
feed this historical data to an AI model like ChatGPT o3 or claude 4 opus and prompt it to:
- identify daily/weekly trends
- factor in promo lifts & seasonality
- adjust for anomalies (spikes, one-offs, etc)
- have it return projected demand by SKU:
next 30 days -> next 60 days -> next 90 days
tip: format it as a table for clean parsing later.

3 / automate the alert
now we build the safety net. if stock is running low before you notice, it pings you.
- set the agent to run weekly.
- if forecasted sales for a SKU exceed current inventory levels, trigger a Slack notification
- the alert should specify the SKU, current inventory, and projected stockout date.

4 / why it works
– no more spreadsheet guesswork
– no over-ordering to “play it safe”
– no more scrambling for restocks
this is one of the highest-leverage automations you can build as a DTC operator.
you’ll save cash. reclaim margin. and finally get ahead of demand.
we use this for brands that want to scale without stockouts.
steal it. deploy it. own your ops.
