Golden River Stone LLC

We build the back office your business never had.

Golden River Stone is a small U.S. company that automates the repetitive work of owner-operated businesses: quote and invoice follow-up for service contractors, brand outreach for Amazon sellers, and custom software on request. We also run our own small, authorized retail operation.

Services

Three things we do well. Everything else on request.

Every service shares the same habit: fewer, better-run things, done with care for the people on the other end — a shop owner waiting on a quote, a seller waiting on a brand, a brand trusting us with their name.

Back-office automation for service contractors

For electrical, HVAC and plumbing shops that run on Jobber. We follow up on every unanswered quote, remind customers about unpaid invoices politely, and watch that Jobber and QuickBooks stay in sync — delivered as a monthly service we set up for you.

  • Quote follow-up written in your shop's voice
  • Invoice reminders that keep the customer
  • A weekly check that your books match your jobs

Brand outreach for Amazon sellers

Finding brands and asking for wholesale accounts is slow, repetitive work. Our outreach engine researches brands with public wholesale programs, writes the first email and the follow-ups, and sorts the replies. You approve every send.

  • Brand lists built from public wholesale pages
  • Compliant sequences: address, opt-out, no spam
  • Sends from your own Gmail or Google Workspace mailbox

New to Amazon? Our free step-by-step courses cover the whole setup, U.S. and Europe.

Custom builds, on request

Websites, integrations between the tools you already pay for, internal dashboards, email and back-office automation, assistants that answer customers. Describe the problem; we scope it in writing, build it, and hand it over with documentation.

  • Fixed-price scope agreed before work starts
  • You own the code, the accounts and the data
  • No lock-in: everything runs without us if you want

How we work

Small, deliberate, and easy to reach.

1

We listen first

Whether it's a shop owner describing a bottleneck or a brand describing their channel policy, we start by understanding the actual constraints before proposing anything.

2

We build narrow, then prove it

We would rather do one thing well — one workflow automated, one order fulfilled correctly — than promise a broad platform on day one.

3

We stay reachable

No ticket queues, no chatbots standing between you and an answer. Email reaches a person who can actually make a decision.

For brands

Evaluating us as a wholesale account?

We are a new, small, authorized reseller — not a liquidator, not a marketplace arbitrager. We buy on your terms, list accurately, and hold to your pricing policy. If you're a U.S. brand open to a new authorized account, we'd welcome a conversation.

  • Authorized purchasing, no grey-market sourcing
  • MAP and channel policy respected by default
  • Small enough to be responsive, careful by design
