About
Built by a seller who sources every day.
I'm Simon Knight, a UK-based Amazon FBA reseller and the person behind FBA Mogul, Invoice Harvester, and everything else on this page.
I run FBA Mogul, a YouTube channel, a Discord community, and a mentoring programme for Amazon sellers. It's where I share the sourcing strategies, workflows, and mistakes that shape how I source on Amazon every day. The community that's grown around it is why I'm building software at all.
Why Invoice Harvester exists
Every Amazon seller eventually needs invoice PDFs for bookkeeping, VAT, reimbursement checks, or just keeping the admin tidy. Amazon does not make that feel like one job. The invoices sit behind order history filters, order detail pages, invoice menus, and marketplace-specific accounts.
Invoice Harvester exists because that is exactly the kind of admin work software should remove. It uses the Amazon session you already have open in Chrome, scans your own order pages, and saves detected invoice PDFs locally. No Amazon credentials collected, no security prompt bypassing, and no pretending a narrow tool needs to be bigger than it is.
