## Account and setup

<AccordionGroup>
  <Accordion title="What is Sellfern?">
    Sellfern is a custom print-on-demand (POD) and personalized product fulfillment platform (similar to Printify or Printful) integrated with a powerful multi-channel e-commerce operating system. It supports fulfillment for standard apparel as well as custom home decor and personalized gifts like ornaments, acrylic plaques, custom lamps, tumblers, and phone cases. It brings order management, fulfillment operations, custom supplier setups, AI listing workflows, and financial reporting into one workspace.
  </Accordion>

  <Accordion title="Can I use Sellfern only for mockups and AI designs?">
    Yes. Sellfern includes a dedicated creative workspace called **Listing Studio** where you can generate AI product designs, remove backgrounds, upscale artwork, and create realistic mockup sets without configuring stores or using our fulfillment features.
  </Accordion>

  <Accordion title="Do I have to use Sellfern's fulfillment network, or can I use my own suppliers?">
    You can do both. While Sellfern offers built-in integrated suppliers (like Printway) for automatic print-on-demand and custom gift fulfillment, you can also register your own custom manufacturing or shipping partners under **Settings → Suppliers** and manually assign costs and track orders in the Ledger.
  </Accordion>

  <Accordion title="What marketplaces are supported?">
    Sellfern supports Etsy, Shopify, Amazon, WooCommerce, Faire, and custom storefront workflows.
  </Accordion>

  <Accordion title="How do I reset my password?">
    Go to **Settings → Change Password**. Your new password must be at least 8 characters long.
  </Accordion>

  <Accordion title="How do I add team members?">
    Admins can go to **Settings → Users** to add users, assign roles, configure store access, and set page permissions.
  </Accordion>

  <Accordion title="Can I connect multiple shops?">
    Yes. Add stores in **Settings → Stores**, assign each a unique store code, and manage active status. Store selection helps consolidate and filter data across the workspace.
  </Accordion>
</AccordionGroup>

## Orders and fulfillment

<AccordionGroup>
  <Accordion title="Why are my orders not syncing?">
    Sellfern can ingest orders through Gmail Live Sync, CSV import, and manual entry. If orders are missing, open **Orders → Ingestion**, use the relevant sync history or debug tools, and try a narrower date range or batch size.
  </Accordion>

  <Accordion title="How do I handle missing tracking numbers?">
    Add tracking details in the Fulfillment tab. Supplier-connected workflows can also update tracking through the Sync Hub when configured.
  </Accordion>

  <Accordion title="What is the Out of Balance tab?">
    **Out of Balance** shows orders where recorded totals do not match expected values. Review these orders for pricing, refunds, shipping, fees, or parser discrepancies.
  </Accordion>

  <Accordion title="What does Failed Ingestions mean and how do I fix it?">
    Failed ingestions are source records that Sellfern could not parse into orders. Review the error context, use debug tools when available, or open the record in Manual Entry to resolve it.
  </Accordion>
</AccordionGroup>

## Costs and analytics

<AccordionGroup>
  <Accordion title="How do I add custom supplier costs?">
    Use the Ledger Cost Table to enter order-item costs and assign suppliers. Manage supplier records from **Settings → Suppliers**.
  </Accordion>

  <Accordion title="Why is my net profit showing incorrectly?">
    Net profit is calculated as Gross Profit minus Operating Expenses. Check that expenses are logged for the same date range you are analyzing.
  </Accordion>

  <Accordion title="How are analytics metrics calculated?">
    Revenue excludes tax. Gross Profit subtracts COGS, platform fees, and refunds. Net Profit subtracts operating expenses from Gross Profit.
  </Accordion>

  <Accordion title="How does ad spend VAT work?">
    Sellfern automatically adds 5% VAT to recorded ad spend expenses and tracks the VAT component separately.
  </Accordion>
</AccordionGroup>

## Listing Studio

<AccordionGroup>
  <Accordion title="How does AI optimization work?">
    Listing Studio uses AI to generate and improve product titles, descriptions, shop stories, and image assets. Provide clear product inputs and use high-resolution images for best results.
  </Accordion>

  <Accordion title="What are credits and how are they used?">
    Credits are consumed each time you use an AI generation feature. Your available balance appears in Listing Studio.
  </Accordion>

  <Accordion title="Can I use images generated by Listing Studio commercially?">
    Listing Studio outputs are intended to help create assets for your listings, but you are responsible for confirming that your inputs, generated outputs, and marketplace use comply with applicable rights, marketplace policies, and Sellfern's terms.
  </Accordion>
</AccordionGroup>

## Technical issues

<AccordionGroup>
  <Accordion title="Which browsers are supported?">
    Sellfern is optimized for Chromium-based browsers such as Chrome, Edge, and Brave, plus Safari. Keep your browser updated.
  </Accordion>

  </Accordion>

  <Accordion title="What do 401 and 403 API errors mean?">

  </Accordion>

  <Accordion title="How do I contact support?">
    Open **Support** in the main sidebar and submit a ticket with issue details, screenshots, and relevant IDs.
  </Accordion>
</AccordionGroup>
