A buying scenario

The order is placed. The follow-up is still work.

An ecommerce team already has a forecast and a way to create purchase orders. The bottleneck comes afterward: supplier confirmations, changed prices, tracking numbers, and shipments arriving in parts.

Illustrative scenario. Use it to plan your evaluation; it is not a customer results claim.

What to prove in your trial

Can the team identify what is still outstanding without searching through separate email threads?

  • Follow one order from confirmation through a partial delivery.
  • Check the remaining quantity against the supplier update and receiving record.
  • Make the next follow-up action clear before placing a replacement order.

From our customers

Whitman’s keeps a broad catalog moving.

Whitman’s

Many brands. Many suppliers. One current PO.

The grooming-supply retailer brings supplier packs, minimums, and prices into the order before sending. Confirmations, shortages, and changed costs then become reviewable PO updates, keeping buying, receiving, and accounting on the same page.

Read the customer story ↗

One buyer. One purchasing story.

For the operator behind a growing online store.

Your online store sells supplies, replacement parts, and equipment from different brands. Bestsellers need stock; slower products tie up cash. You need to know what to reorder, what suppliers have confirmed, and what actually arrived—without spending the day chasing emails.

Where LineNow fits

Shopify already provides purchase orders, suppliers, inventory locations, and receiving workflows. See Shopify’s native workflow ↗

LineNow connects the buying decision to supplier terms, conversations, reviewed changes, receipts, and invoice context. The team follows the purchase through every change until stock is received.

For ecommerce businesses that carry stock and buy from multiple suppliers—whether you manage purchasing yourself or work with a buying team.

01Build the reorder

Put the buying budget into the right products.

The buyer reviews stock and sales across the catalog. Shampoo needs 24 more gallon bottles; clipper blades need six units; dryers already have enough stock. Check open orders, then buy the shampoo as six cases of four with the supplier’s pack size, minimum, and price in view.

  • ✓Review sales, stock, and the items that need replenishing.
  • ✓Check open POs before placing another order.
  • ✓Buy in the supplier’s packs, with minimums and prices in view.

02Review supplier changes

Catch the supplier’s changes before stock arrives.

The supplier confirms four cases now and two on Friday, with the price changing from $18 to $19 per gallon. LineNow reads the reply into a reviewable PO update. The buyer checks the new cost and delivery plan so the warehouse and finance team see the same order.

  • ✓Review the supplier’s confirmed quantities and delivery plan.
  • ✓Check price changes before the invoice arrives.
  • ✓Keep the message and accepted updates with the PO.

↳The changed cost and remaining delivery stay with the PO.

03Receive and reconcile

Receive the stock. Keep the balance open.

Four cases reach the main warehouse: 16 gallon bottles received, eight still due. Record the actual receipt against the PO and update the mapped Shopify item and location. Keep the remaining quantity open, with the agreed price and supplier document ready for bill review.

  • ✓Count the delivered cases against the current PO.
  • ✓Update the mapped Shopify item at the receiving location.
  • ✓Keep the open balance and invoice evidence ready for review.

Practical questions

Before you connect the workflow.

Understand the setup, the handoffs, and what your team reviews along the way.

Confirm the Shopify variant and receiving-location mapping, inventory permissions, and the relationship between supplier cases and sellable units. Shopify-sourced stock uses the available quantity at the mapped location. Record the starting balance, receive a small authorized delivery once, and reconcile the resulting stock change while accounting for other sales or adjustments. Agree who investigates a missing update before anyone repeats the receipt.
Do not assume that a Shopify connection mirrors every native purchase order, transfer, supplier record, or accounting transaction. Agree which system owns each record and confirm the required handoffs during setup. Demonstrate the complete flow with your item and location mappings, including a partial receipt. Integration scope and accounting connections should be reviewed separately from the supplier ordering workflow.
Ecommerce owners, operators, and purchasing teams that carry inventory and buy from multiple suppliers. Your store may sell specialist equipment, repeat-purchase supplies, replacement parts, or a mix. LineNow connects reorders, supplier terms, order changes, receipts, and costs. You do not need physical retail stores.
Connected Shopify product, sales, inventory, and location information can support the buying review in LineNow. Configure each item’s replenishment settings and supplier mapping, review the suggested quantities, and check outstanding purchases before sending the order. The buying team remains responsible for the final plan.
Yes. Map the Shopify sellable item to the supplier item and its purchasing pack. For example, six cases of four gallon bottles represent 24 sellable bottles. Verify the units, pack relationship, price basis, and receiving setup during onboarding.
LineNow can read supplier confirmations, shortages, price changes, and revised dates into reviewable PO updates. The buyer can inspect the message and changed values together so receiving and finance have the current purchasing record.
Yes. Record the quantity that actually arrived against the purchase order and keep the remaining balance open. Shopify inventory updates require correct product and receiving-location mappings. Agree which system records each receipt during setup to avoid recording the same delivery twice.
Yes. Physical stores can be additional stock locations alongside your ecommerce warehouse. Configure the supported locations and item mappings, then test buying and receiving at each intended destination. Central warehouse purchasing and branch requests can be scoped if you need them.
Shopify already supports purchase orders and receiving. Evaluate LineNow when your buying process also needs supplier pack and price context, shared conversations, reviewable changes, partial receipts, and accounting evidence. Compare the complete supplier workflow using one of your real orders.
