The Shopify Inventory Management App That Reads Your Supplier Invoices

Smart Restock is the Shopify inventory management app built around a single idea: your supplier sends an invoice, Smart Restock parses it, and your Shopify stock levels update automatically — no manual data entry, no spreadsheets, no retyping. It's Shopify inventory automation for the step every other app leaves alone: receiving.

Not another inventory dashboard

Most Shopify inventory apps help you view stock: dashboards, low-stock reports, forecasts, transfer screens. Useful — but the actual work of getting new stock into Shopify after a delivery is still on you. You open the supplier's PDF, find the matching product in Shopify, type the quantity, type the cost, click save. Multiply by 40, 80, 200 line items per invoice.

Smart Restock automates the receiving step itself. Invoice in, inventory updated. That's the whole product.

Typical inventory app

  1. 1. Receive supplier invoice
  2. 2. Open PDF, read every line
  3. 3. Search Shopify for each SKU
  4. 4. Type quantity received
  5. 5. Type unit cost
  6. 6. Repeat 200×
  7. 7. Reconcile in spreadsheet

Smart Restock

  1. 1. Upload the invoice.
  2. (That's it. Review the parsed lines, approve, done.)

How to update Shopify inventory automatically in three steps

1

Upload or forward

Drop the supplier invoice — PDF, Excel (.xlsx), or forwarded email (.eml) — into Smart Restock.

2

Parse & match

Smart Restock reads every line item and matches it to your Shopify SKUs automatically.

3

Inventory updates

Approve the batch and quantities post to Shopify — across every location, with weighted-average cost.

That's how you upload inventory to Shopify without typing a single line — and how you import a supplier invoice into Shopify in about two minutes, even for a 200-line PO.

Supported invoice formats

PDF — digital or scanned supplier PDFs, single or multi-page, with tables, mixed columns, discount lines, and per-line tax.

Excel (.xlsx) — supplier price lists and shipment manifests in any column layout. Smart Restock asks once which column is which and remembers it for that supplier.

Email (.eml) — forward the supplier's email to the address Smart Restock provisions for your store. Attachments and invoices embedded in the email body both work.

This is built for real-world supplier invoices — the messy ones your vendors actually send — not just clean spreadsheets. If a format ever breaks the parser, send it to support and we'll extend it.

Who this Shopify inventory management app is for

Shopify merchants who receive regular supplier shipments and are done retyping invoices. Especially: apparel brands restocking sizes and colours each drop, food & beverage stores with weekly distributor deliveries, retail shops juggling multiple wholesalers, and wholesale operators managing dozens of supplier catalogs.

Frequently asked questions

How do I upload inventory to Shopify automatically?

Install Smart Restock from the Shopify App Store, then upload or forward the supplier invoice you'd normally retype. Smart Restock parses every line item, matches SKUs to your Shopify catalog, and posts the inventory adjustments — including weighted-average cost — in one click. No CSV, no spreadsheets, no manual data entry.

Can I import a supplier PDF invoice into Shopify?

Yes. Smart Restock reads any supplier PDF — digital or scanned, single or multi-page — extracts product names, SKUs, quantities, and unit costs, and pushes the inventory update straight to Shopify. No template setup or reformatting required.

How is Smart Restock different from other Shopify inventory apps?

Most Shopify inventory management apps focus on viewing stock and forecasting. Smart Restock focuses on the receiving step — turning a supplier invoice into an updated Shopify inventory count automatically. It complements a dashboard-style app; it doesn't replace one.

What invoice formats does Smart Restock support?

PDF (digital and scanned), Excel workbooks (.xlsx), and email files (.eml — including invoices in the email body, not just attachments). Multi-column layouts, mixed currencies, and discount lines are all handled by the parser.
