Direct-to-Consumer

Every stockout is a sale you handed to a competitor.

D2C brands lose revenue not to weak demand — but to inventory blind spots. StackPlan gives you a 12-week forward view per SKU, automatic reorder signals, and PO drafts before the shelf goes empty.

The D2C Problem

Stockouts don't happen suddenly.
They're visible weeks in advance.

D2C brands manage inventory reactively — discovering problems after the sale is gone. StackPlan gives you the forward view to act before revenue is at risk.

You find out too late

Stockouts appear in your dashboard when the order fails — not three weeks before, when there was still time to reorder. By then, the customer has already gone elsewhere.

Spreadsheets can't keep up with demand

Shopify sales shift daily. Amazon velocity spikes without warning. Spreadsheet reorder tracking can't update fast enough — and by the time you catch the signal, it's too late.

Operations can't scale without systems

As SKU count grows, manual reorder tracking breaks down. Without a system that acts autonomously, every new product line adds more firefighting — not more revenue.

Platform Capabilities

From demand signal to approved PO.
Every step, automated.

Five deeply integrated capabilities — each solving a specific gap in how D2C brands manage inventory today.

Demand Forecast

Know what's coming 12 weeks before it arrives.

Six ML models backtested automatically per SKU. The most accurate one selected for you — per channel, per variant. Handles spikes, seasonality, and intermittent demand.

D2C Use Cases

Built for the moments
that define D2C revenue.

Four scenarios every D2C brand faces. One platform that handles all of them — automatically.

Trending SKU goes viral overnight

A product gets picked up by an influencer. Velocity triples in 48 hours. StackPlan detects the spike, re-runs the forecast, and has a PO draft ready before your team starts the morning.

Demand spike detected

Runway: 6 days

PO drafted: $720

Result

Zero stockouts from the spike. PO approved in 90 seconds. Supplier notified before competitors reacted.

Supplier delays your biggest reorder

Your primary supplier pushes back delivery by 14 days. StackPlan runs the impact simulation, calculates the stockout window, and recommends your backup supplier with an alternative PO ready to send.

Supplier delay +14d

Service level risk: 71.4%

Alt PO ready: $880

Result

Backup supplier activated in 4 minutes. Service level maintained above 95%. No manual intervention needed.

Pre-launch inventory planning

You're launching a new SKU next month. StackPlan uses comparable SKU velocity to project opening demand, sets safety stock levels, and stages the first reorder signal before you've sold a single unit.

Launch forecast ready

Safety stock set

First reorder W3

Result

New SKU launched with 8-week runway. First reorder signal fired before stock dropped below threshold. Zero launch stockouts.

End-of-season clearance & restocking

Season ends, slow-moving stock piles up while fast-movers run dry. StackPlan identifies which SKUs to reorder vs wind down — and flags where holding cost exceeds reorder benefit.

14 SKUs to wind down

6 SKUs to reorder

$42K freed

Result

Cash freed from dead stock reinvested into fast-movers. Working capital efficiency up 22% vs prior season.

One-click Shopify OAuth and Amazon CSV. 24 months of order history on first sync, updated hourly. No manual exports.

⚡ Under 30 seconds

Forecast Demand per SKU

Six ML models backtested against your data. The best one selected automatically per SKU — producing a 12-week demand signal that adapts to spikes and seasonality.

⚡ First forecast in minutes

Autonomous Reorder Signals

At 02:00 every night, StackPlan scans every SKU. When a threshold is crossed, it drafts the PO and queues it for approval — no manual trigger.

⚡ Drafts ready every morning

Review, Approve & Sync

Approve POs through a multi-level workflow. Tax-compliant documents generated instantly. Approved POs sync to Tally, Zoho Books, or SAP automatically.

⚡ One click to approve

Before vs After

Not a dashboard.
A system that acts.

Most D2C brands discover stockouts after revenue is already gone. StackPlan changes that — from reactive to proactive, from manual to autonomous.

Without StackPlan

Weekly spreadsheet reviews

Manually checking stock levels every Monday. By Thursday the data is already stale.

Stockouts discovered after the fact

Orders fail. Customers leave. You find out when the revenue is already gone.

Gut-feel reorder decisions

No model, no confidence score. Just "it feels like we should order more."

Manual PO creation & approval

Every PO typed manually. No workflow. No audit trail. Finance can't reconcile.

Supplier issues found too late

Delays discovered when the shipment doesn't arrive — not when the booking is made.

With StackPlan

Live forecast updated hourly

Six ML models per SKU, backtested automatically. Always current, always accurate.

Stockout signals 12 weeks early
