LineNow vs Katana: Procurement Workflow vs Production Scheduling

Katana owns the production schedule. LineNow owns the supplier conversation. They are different sides of the same supply chain.

Katana Cloud Inventory is a cloud-based manufacturing and inventory platform built for make-to-order brands — production scheduling, work orders, Bill of Materials management, material availability checks, and Shopify sales-order-to-production-order automation. LineNow is a closed-loop procurement platform built around a living purchase order — each buying step stays connected in one operating record, from deciding what to order, sending the PO through supported supplier channels, reading the supplier's reply, receiving goods, and updating inventory.

Both tools auto-generate purchase orders. Both handle BOMs. The difference is what each is built around: Katana is built around the production workflow (what you make), and LineNow is built around the procurement workflow (what you buy and from whom). For many manufacturers, that is the right decomposition — and the tools pair naturally.

TL;DR

Does LineNow track raw materials?

Yes. LineNow tracks raw materials, ingredients, components, packaging, kits, bundles, and light assemblies for procurement. It connects BOM or recipe usage to component stock, supplier-linked purchase orders, receiving, supplier price changes, substitutions, yield ratios, and the next replenishment recommendation.

The boundary is production execution. If "raw materials tracking" means shop-floor work orders, WIP stages, routing, capacity planning, and production scheduling, Katana is deeper. If it means knowing which raw materials to buy, which supplier owns them, what the supplier confirmed, what arrived, and how component costs affect finished-goods margin, LineNow is built for that workflow.

Where Katana fits

Katana has earned its position in the Shopify manufacturing stack for good reason. If you design and manufacture physical products — apparel, cosmetics, electronics, furniture, food and beverage — and your core operational constraint is the production schedule, Katana handles the make-side cleanly:

• Sales order → production order automation. When a Shopify order comes in, Katana can trigger a production order, check material availability, and schedule the work order across your shop floor. For a made-to-order brand, this is the workflow that matters most.
• Multi-level BOM. Finished goods, sub-assemblies, components, raw materials — Katana handles nested BOMs with explicit quantities, yield coefficients, and routing steps. The finished good cost rolls up dynamically as component prices change.
• Work-in-progress (WIP) tracking. Katana tracks material status from raw inventory through each production stage. A production manager can see what is in raw stock, what is currently on the floor, and what is finished and ready to ship.
• Material availability checks. Before committing a production run, Katana surfaces whether all BOM components are available or back-ordered. This prevents the expensive mistake of starting a run you can't finish.
• Shopify-first integration. For DTC brands selling primarily on Shopify, the sales order ingest is tight. Sales drive production planning, production planning drives material requirements, material requirements drive POs.

Katana is a credible choice when:

• Your primary operational pain is production scheduling — work orders, routing, WIP visibility, and capacity planning.
• You manufacture to order on Shopify and need production orders to auto-generate from sales orders.
• You have multi-stage production with meaningful WIP that needs to be tracked between stages.
• You are a brand replacing spreadsheet-driven production scheduling with a purpose-built production system.

Where Katana stops working for SMBs

For an operator whose primary pain is the supplier side — what to buy, sending POs, parsing supplier replies, handling substitutions, receiving goods accurately, getting bills into QuickBooks — Katana leaves significant gaps.

The supplier-reply problem is unaddressed. Katana generates POs from material requirements. It does not parse what the supplier sends back. The EDI 855 acknowledgment that modifies quantities and ETAs, the email from a components supplier saying "your copper tubing order ships Friday but we're short 400 units, subbing 5/8" for 3/4" per your approval", the WhatsApp message with the photo of the packed pallet — none of that becomes structured PO or production-schedule state. The operator reads it, types it in, and hopes they didn't miss anything. That is open-loop procurement: state change that requires a human in every transition.

For a manufacturer with 3-week lead times, a missed supplier-reply update creates compounding production-schedule risk. The ETA delay that arrived in email six weeks ago shows up as a production stop next month.

No agentic supplier-reply monitoring. Katana has a supplier management section for vendor contact information and purchase history. It is not a Layer 1 AI that reads email bodies, PDF confirmations, EDI 855/856/870 documents, and WhatsApp messages into reviewable open-PO updates. That capability is an architectural choice made at day one, not a feature added to a production system.

Replenishment is min-stock alerts, not statistical forecasting. Katana's reorder points are set by the operator as minimum stock levels. When inventory drops below the threshold, Katana flags a reorder. This works for simple, steady-demand components. It does not handle the demand-pattern classification (smooth, intermittent, erratic, lumpy) that prevents over-ordering on slow-moving specialty parts and stockouts on high-velocity materials. The Syntetos–Boylan Approximation and the SBC framework — the statistical methods that determine which forecast model applies to which SKU — are not part of Katana's inventory math. See Coefficient of Variation for the demand-classification methodology.

Supplier channels are narrower. Katana communicates with suppliers primarily through email and a supplier portal workflow. For a manufacturer with suppliers across countries and channels, WhatsApp confirmations, EDI acknowledgments, and portal status changes can still become side processes. Meeting each supplier in its configured channel is what determines whether orders close cleanly or require manual follow-up.

Pricing and packaging complexity. Katana's pricing is built around production and MRP capability, with tiers and add-ons for deeper manufacturing needs. For a manufacturer whose primary pain is the buyer-side procurement workflow rather than the production schedule, that package can buy a great deal of production capability they may not need.

Where LineNow fits

LineNow is procurement-first. The architectural centerpiece is the closed loop on the supplier reply — not the production schedule, not the work order, but the state change that happens after you place an order and the supplier responds.

The complete loop:

• Decide what to buy. POS-driven consumption feeds the replenishment math nightly. Statistical replenishment using the SBC framework classifies each item's demand pattern (smooth, intermittent, erratic, lumpy) and applies the right forecast. The Syntetos–Boylan Approximation handles non-smooth demand. Decay-aware PAR for perishables. Safety stock incorporates both demand variability (σ_demand) and lead-time variability (σ_lead): z × √[(lead_time × σ²_demand) + (avg_demand² × σ²_lead)]. The system builds a buy recommendation; the operator approves.

• Send the PO. Email, WhatsApp Business, EDI X12 850, or supplier portal — using the configured channel for each supplier. The PO goes out the right way for each supplier without the operator switching between tools.

• Parse the reply. Layer 1 AI reads the EDI 855 acknowledgment, the email with a PDF attached, the WhatsApp confirmation, the web-portal status page. Price changes, quantity modifications, substitutions, ETAs, partial shipments — the PO receives structured updates. This is the step that keeps the production planner's view of inbound components accurate without manual entry.

• Receive goods. Receiving event linked to the PO, inventory updated in the same session, discrepancies flagged. The bill matches the received state of the PO, not the original.

• Push the bill. Bills post to QuickBooks Online or Xero with COGS classification, vendor match, and PO linkage. Month-end close on procurement spend is minutes, not a half-day reconciliation.

• Recommend the next order. The cycle restarts. Updated supplier reliability, actual lead times, consumption since last receipt — all feed the next replenishment run.

Layer 2 AI: a structured-data analytics chatbot and AI order builder pointed at the actual operating data — component spend by supplier, supplier reliability by SKU, BOM cost trends, inventory turns by category.

Team collaboration: every supplier email brought into the system, attached to its PO, visible to the whole team. Multiple people can read and reply to the same supplier thread without sharing a personal inbox.

Multi-vertical: retail, dropship, restaurant, and light manufacturing all run in one account, each with its own replenishment policy and POS connection.

$100/month flat — core workflow, supported users, suppliers, locations, and channels in one plan. No per-seat fees, no production add-on stack.

The honest distinction

Katana and LineNow are genuinely different categories addressing adjacent problems.

Katana's competence is the production workflow: the moment a sales order arrives and triggers a production schedule, the moment material requirements are computed from the BOM, the moment work orders are dispatched across the shop floor. Inside that category — make-to-order brands with serious production complexity — Katana is one of the more capable tools available at SMB pricing.

LineNow's competence is the procurement workflow: the moment a buy decision is made, through the PO going out, the supplier responding, goods arriving, and the bill posting to accounting. LineNow's architectural differentiator is that those state changes stay attached to the living PO, with reviewable updates before AP receives the bill.

Neither tool does both well. The healthy decomposition for a complex manufacturer is: Katana handles production (work orders, routing, WIP, material availability) and LineNow handles procurement (buy recommendations, PO execution, supplier-reply parsing, receiving, bills push). They address adjacent state in the manufacturing workflow without conflicting.

For a lighter manufacturer — an assembler, a CPG brand, a restaurant running a production kitchen — who needs BOM costing and procurement but not production scheduling with WIP tracking, LineNow can handle the buy-side scope without adding a production-scheduling suite.

When to choose Katana

You manufacture products with genuine production scheduling complexity: multiple production stages, WIP tracking across a shop floor, capacity planning, make-to-order workflows triggered by Shopify sales orders. Your primary pain is the production side — material availability, work order dispatch, and routing visibility — not the supplier communication side. You're willing to manage supplier replies manually or handle the gap with a secondary tool.

When to choose LineNow

Your primary pain is the buyer-side workflow: deciding what to buy, sending POs through mixed channels, parsing what suppliers send back, receiving goods accurately, and getting bills into QuickBooks without manual reconciliation. You may be a light manufacturer, an assembler, a CPG brand, or a restaurant — where BOM costing matters but full production scheduling does not. You want statistical replenishment that adapts to each item's demand pattern, not a manual min-stock threshold. You want supplier replies, receiving variance, and invoice context reconciled upstream instead of rebuilt in AP.

The pairing case

For a serious make-to-order manufacturer with both production complexity and supplier-side volume: Katana handles production scheduling (work orders, WIP, material availability checks), and LineNow handles the closed-loop procurement side (supplier-reply parsing, multi-channel PO execution, statistical replenishment, receiving, bills push). The split is clean — Katana owns the make side, LineNow owns the buy side. Neither tool conflicts with the other.

If the supplier conversation is where your procurement loop breaks — reply parsing, multi-channel PO execution, receiving accuracy, bills matching — start the LineNow 90-day free trial. Connect your POS, forward your supplier email, place one order. The closed loop becomes obvious in the first week.
