Turn Shopify products into buyer-ready line sheets without rebuilding them in Canva.
LineProof helps small brands ship accurate wholesale PDFs, live buyer links, and readiness checks from the product data they already maintain.
Wholesale packet
Before buyer outreach
Input
Connect Shopify or upload product CSV, images, variant table, wholesale price columns, season tag, buyer notes, MOQ, and ship-window assumptions.
Checks
LineProof flags missing wholesale prices, image gaps, inconsistent variant names, sold-out items included in a buyer packet, missing MOQ, and stale product descriptions.
Output
A retailer-ready PDF line sheet, live buyer link, CSV backup, update log, and a send-ready email block for boutique outreach or showroom follow-up.
Narrow customer + paid problem
Wholesale buyers need a clean packet before they reply
Small apparel and accessories brands often sell DTC first, then scramble to present seasonal products, variants, MOQ, wholesale price, imagery, and availability in a retailer-friendly format.
CSV → Canva → PDF breaks every season
The workaround works once. It becomes paid pain when every product edit, colorway change, sold-out SKU, or new buyer list forces another manual export, layout pass, and resend.
Enterprise wholesale tools are too heavy for the first 20 stockists
The narrow buyer is not a mature wholesale team. It is a founder, wholesale assistant, or showroom rep who needs a reliable line-sheet packet this week without migrating commerce systems.
Day-in-the-life
A buyer asks for a line sheet. The founder opens three tabs and starts exporting.
The founder has Shopify products, photos in folders, wholesale price logic in a spreadsheet, and boutique buyers asking for a clean packet. A product change means another CSV export, another Canva layout tweak, and another PDF that may already be stale.
The cost is directional but real: delayed buyer replies, founder hours lost before markets or trade shows, stale availability in buyer packets, and wholesale opportunities that look less professional than the brand itself.
Shopify-to-line-sheet import
Pull product titles, images, variants, SKUs, tags, and availability into a wholesale layout without making the founder rebuild the collection in Canva.
Wholesale readiness audit
Highlight missing wholesale price, pack size, MOQ, color/size ambiguity, low-resolution photos, and products that should not be shown to buyers yet.
Season and buyer versions
Save separate SS/FW, holiday, showroom, and boutique-specific packets while preserving the source-of-truth product data behind each version.
One-click refresh
When Shopify changes, regenerate the packet and show what changed so the founder can resend only the corrected buyer link or PDF.
Concierge packet first
Early users can submit a Shopify CSV and product image folder for a human-reviewed line-sheet packet before a full app integration is built.
Public evidence
The signal is wholesale-material maintenance, not generic ecommerce automation.
These sources do not prove demand. They justify one concrete validation question: will Shopify-first brands join a waitlist for a human-reviewed line-sheet packet before a full integration is built?

Marketplace context · Faire
Open sourceWholesale discovery platforms create the buyer channel, but small brands still need clean, season-ready sell sheets that can be sent to boutiques before or alongside marketplace onboarding.

Objections
Why not Canva?
Canva is good for design. It is weak as a product-data system when variants, prices, availability, and buyer-specific versions change every week.
Why not Faire?
Faire helps with marketplace discovery. Many brands still need a controlled PDF/link packet for boutiques, showrooms, email outreach, and buyers who ask for a line sheet first.
Why not a full wholesale platform?
The first validation wedge is smaller: help Shopify-first brands produce accurate, buyer-ready materials without adopting another commerce backend.
Will brands pay?
The landing page tests whether small brands will join a waitlist for a $99-$299 concierge line-sheet refresh before automated subscription software exists.
