Run warehouse paperwork, SOWs and billing automatically
A custom AI system for a warehousing client reads receipts, estimates and invoices, generates SOWs, runs billing and handles 28 background automations.
Done with n8n
What they did
The team built one custom operating system (130k lines of code, 41 screens, 50 tables) after mapping every workflow by meeting the staff doing the work, removing unneeded processes, and wireframing the full flow. The AI reads inbound receipts, estimates, and invoices then structures the data automatically; generates SOWs in one click; runs billing across three rate models; and triggers 28 background automations for reminders, emails, and documents while managing all 450 active projects in one place.
How it went
Operations consolidated into a single platform. SOW creation fell from an afternoon to instant generation, with billing and routine tasks running without manual effort.
Worth knowing
A mid-market company can complete the full build in one quarter.
Try it yourself with n8n
Build a workflow for my [type of business, e.g. warehousing] that watches [inbox or folder] for new receipts, estimates and invoices, extracts vendor, amounts, dates and line items, and saves them to [spreadsheet or system]. Then have it draft a statement of work or billing summary for each [client or job] from that data. It is finished when a test document flows through end to end and produces a draft. Make it pause for my approval before it sends any message or issues any bill.
