LineNow vs Inventory Planner: Forecast + Workflow vs Forecast Alone

Inventory Planner is a forecasting and replenishment app built for Shopify and a handful of other retail platforms, focused on demand prediction and reorder recommendations for e-commerce brands. LineNow is a procurement and inventory platform for SMBs that does forecasting the full purchasing workflow. They overlap on the math; they diverge on what happens after the recommendation.

TL;DR

Where Inventory Planner fits

Inventory Planner is a competent forecasting tool for established e-commerce brands that have outgrown spreadsheet-based replenishment. Their math is real — they handle seasonality, lead times, and supplier MOQs, and they produce defensible reorder recommendations. For a $5M+ DTC brand on Shopify Plus with multiple warehouses, the product genuinely works.

Strengths:

• Multiple forecast methods to choose from per SKU
• Seasonality detection
• Lead time variability handling
• Multi-warehouse allocation
• ABC analysis and stock classification
• Integrations with Shopify, BigCommerce, Magento, NetSuite

Where Inventory Planner stops working

• PO generation, not PO workflow. Inventory Planner produces a PO PDF. After that, you email it to your supplier. The reply lands in your inbox; you read and reconcile manually. Inventory Planner does not parse supplier replies, track price changes, or update order status without you.
• No restaurant / recipe coverage. Food service is not in scope.
• Price. Entry tier is $249/month and scales fast. For an SMB doing $1–3M in revenue, this is meaningful budget.
• No accounting integration depth. Bills don't push to QuickBooks with COGS classification.
• No WhatsApp, EDI, or supplier portal channels. Email-PO-only assumed.
• Not POS-native for non-e-commerce. Square and Toast aren't supported.

Where LineNow fits

LineNow does the forecasting (with SBA / Croston math that handles intermittent and erratic demand correctly), and then continues into the workflow Inventory Planner stops at:

• Sends POs via email, WhatsApp, EDI, or supplier portal — whichever the supplier prefers
• AI parses supplier replies (Gmail, Microsoft, forwarded mailboxes, WhatsApp) and updates orders
• Tracks ETAs, price changes, substitutions, partial fulfillment
• Pushes bills to QuickBooks/Xero with COGS classification
• Recipe builder with dynamic margin and substitution for restaurants
• Dropship auto-PO from sales orders
• $50/month flat regardless of revenue

When to choose Inventory Planner

You are a $5M+ DTC e-commerce brand on Shopify Plus or BigCommerce with multiple warehouses. You have a dedicated inventory planner role on your team who runs forecasts and decides what to order. You're already paying for NetSuite or a similar ERP for the rest of the workflow. Inventory Planner is the forecasting layer in a larger stack.

When to choose LineNow

You're an SMB ($500K–$5M revenue) running on Shopify, Square, Toast, or Faire. You want forecasting and the workflow that follows it — POs, supplier replies, bill push, accounting. You'd rather have $50/month and one tool than $300/month and a stack of three. You may have a restaurant, food manufacturer, or dropship operation that Inventory Planner doesn't cover.

The math distinction

Both products do real forecasting. Inventory Planner offers multiple methods (you choose); LineNow uses an opinionated SBC framework (smooth/intermittent/erratic/lumpy classification, with SBA for non-smooth). For experienced inventory planners, choice is a feature. For an SMB owner-operator, opinions are a feature. We're built for the second.
