Build substantial in-house automation, working hand in hand with the owner to understand daily operations, identify repetitive tasks, and turn manual processes into dependable workflows.
Use AI tools, API integrations, and workflow automation to streamline lead handling, quoting, artwork preparation, customer follow-ups, order processing, and production coordination, with review controls where needed.
Improve supplier synchronization so product availability, pricing, images, and garment options remain accurate and consistent.
Strengthen artwork customization and AI-assisted design tools to produce better previews and usable production files.
Connect the website, CRM, payments, shipping, and production systems to reduce duplicate entry, missed handoffs, and manual tracking.
Improve mobile usability, page speed, and the ordering experience to help more customers complete their purchases.
Deliver meaningful product improvements and measurable reductions in manual work, prioritizing closely with the owner to grow sales and increase operational capacity. Our sales are growing with zero effort; we know we can easily quadruple these sales when the website is fully automated and synchronized as it should be.
