Stop updating inventory by hand
Upload purchase orders, packing slips, and invoices — DocToStock handles extraction and matching automatically, so your team spends time reviewing, not re-entering data.
Match extracted lines to your products automatically
DocToStock extracts product lines from supplier documents and automatically matches them to your Shopify products using SKU and barcode — no manual lookup required.
Review and correct before sync
Operators confirm quantities, correct product matches, select the target inventory location, and approve each line before anything changes in your store.
Sync approved inventory to Shopify
Only approved inventory changes are sent back to Shopify, so stock updates stay controlled and auditable.
Frequently Asked Questions
Everything you need to know about syncing Shopify inventory from supplier files.
How does DocToStock connect to my Shopify store?
DocToStock connects securely via Shopify OAuth. It requests permission only to read products, manage inventory levels, and read basic store information.
Does DocToStock update my inventory automatically without review?
No. By default, every extracted supplier update is queued as a review task. Your team verifies matches and approves stock changes before they are synced to Shopify.
What documents can I upload?
You can upload PDF files of supplier invoices, purchase orders, and packing slips.
How does product matching work?
DocToStock extracts item identifiers (SKUs, barcodes, and titles) from your documents and matches them against your Shopify catalog automatically.
Can I select the Shopify inventory location for updates?
Yes. Before syncing, operators select the correct target inventory location configured in your Shopify settings.
Is my data shared or used to train models?
No. Your documents are stored in secure, isolated storage. We use API endpoints with zero-retention policies; your data is never used to train public models.
How many documents can I process during the beta?
The beta program includes a free monthly document allowance, which may be adjusted as we scale.
