Introduction
Selling on major marketplaces like Amazon and Walmart often requires more than just a product listing — many brands and categories require verified invoices and Letters of Authorization (LOAs) to approve sellers and unlock gated categories. This guide explains everything resellers need to know about obtaining marketplace-accepted invoices and LOAs, how Easy Signs Wholesale supports the process, and practical steps you can take to speed up ungating and keep your seller accounts compliant.
Why Verified Invoices & LOAs Matter
Marketplace compliance: Amazon, Walmart, and other platforms request invoices or LOAs to confirm product authenticity and legitimate sourcing.
Ungating restricted brands/categories: Some brands or categories are gated; verified documents are often required to gain approval.
Account protection: Proper documentation reduces the risk of listing removal or account action for sourcing concerns.
Buyers’ trust: Resellers can confidently list and scale products when they have correct provenance.
Easy Signs Wholesale provides verified invoices and brand authorization letters with qualifying purchases to help resellers meet these marketplace requirements.
What Is a Verified Invoice? — Key Elements (Checklist)
A marketplace-ready invoice should include:
Seller / wholesaler name and contact information (Easy Signs Wholesale)
Buyer name and billing address (your business)
Invoice number and date
Purchase order or order reference number (from your account)
Brand/manufacturer name and product descriptions (clear SKU/UPC if available)
Quantity per line item and unit price (unit + total)
Payment method and transaction reference (bank transfer confirmation, etc.)
Shipping address and shipment date (if shipped)
Company tax ID / business registration details (if applicable)
Tip: Keep invoices legible and on company letterhead if possible—marketplaces scan these fields during their review.
What Is a Letter of Authorization (LOA)?
An LOA is a written statement from a brand or its authorized distributor confirming you (the buyer/reseller) are permitted to sell the brand’s products. A proper LOA typically includes:
Brand name and brand representative signature or official stamp
Explicit statement authorizing the distributor (Easy Signs Wholesale) to supply products to resellers
Scope of authorization (specific SKUs, regions, or distribution channels)
Date of issue and validity (if specified)
Easy Signs Wholesale issues LOAs or brand authorization documents where available — these help speed up marketplace approvals.
How Easy Signs Wholesale Provides Documents (Step-by-Step)
Place and pay for your order — Documents are provided only for paid & verified orders.
Request the invoice/LOA — After payment, request documents via your wholesale account or email (wholesale@easysignswholesale.com). Include your order number and the exact products you need documents for.
Verification & document generation — Our team validates the order and generates a verified invoice and/or LOA for eligible brands.
Delivery of documents — Documents are emailed in PDF format (and available in your account) — typically within 24–72 hours after payment verification.
Use for marketplace ungating — Submit the invoice/LOA to the marketplace as part of the ungating process.
Note: Some brands do not provide LOAs; in that case a valid, brand-identifying invoice is the main supporting document.
How to Request Invoices & LOAs (Best Practices)
When requesting documents, provide:
Your Order Number (exact)
Full company name as it should appear on the invoice
Billing & shipping addresses exactly as used for your marketplace account
List of SKUs / product names you need documentation for
Payment confirmation (screenshot of bank transfer or transaction ID) to speed verification
Providing complete and accurate information reduces back-and-forth and shortens turnaround time.

Tips for Marketplace Ungating (Practical Advice)
Match buyer details to marketplace account. Marketplaces cross-check business names and addresses — mismatches slow approvals.
Include brand names clearly. Marketplace reviewers want to see the brand and manufacturer names in the invoice.
Keep paperwork for tax & compliance. Retain invoices and LOAs for at least 3–7 years, per business/tax record rules.
Use the original invoice — don’t alter it. Never edit or fabricate invoices; marketplaces can detect tampering and suspend accounts.
Request LOAs early. If a brand requires an LOA to list, request it as soon as you place your paid order.
Provide clear photos if requested. Marketplaces sometimes request product images or packaging photos along with invoices.
Common Reasons Marketplaces Reject Documents (and How to Avoid Them)
Missing brand or seller information: Ensure the invoice lists the brand and wholesaler details.
Handwritten or unclear invoices: Use stamped/printed PDFs — not handwritten notes.
Inconsistent buyer details: Use the exact company name and address registered on your seller account.
Invoices without proof of payment: Submit payment receipts or bank transfer confirmations when asked.
Unverifiable sources: Use authorized wholesalers (like Easy Signs Wholesale) rather than unknown middlemen.
Timeline & What to Expect
After payment verified: Documents typically issued within 24–72 hours.
Marketplace review: Once submitted, Amazon/Walmart review time varies — anywhere from a few hours up to several days.
If additional questions arise: Marketplaces may request extra proof — be ready to supply invoices, packaging photos, or LOAs.
Record Keeping & Best Practices for Sellers
Store documents securely (cloud + local backup).
Keep order numbers and payment confirmations linked to each invoice.
Maintain a document log of LOAs and expiry dates for brands that set validity windows.
Train staff in correct submission procedures to avoid rejections.
