The problem
Order number 147 of the day. Check stock, generate the shipping label, send the tracking number to the customer, push the receipt to accounting, decrement inventory on Amazon and in the shop. Five tools, fourteen clicks.
The exact same fourteen clicks as order 146. And 145.
At two hundred orders a day, that's a full-time job for someone who decides nothing — they just transfer data. And that's exactly the position that breaks first: during the holiday rush, on the first sick day, with the next resignation.
The uncomfortable part: every click is a chance for a typo. Wrong address, sold-out item still listed, tracking email forgotten — the customer always notices first.
This showcase shows how all channels feed into one pipeline — turning ten minutes of clicking into thirty seconds of machine time.
Manual order processing pushes many companies to their limits. Typical symptoms: A five-person team spends over 8 hours daily transferring orders from Shopify, Amazon, and WooCommerce into various systems manually. Each channel has its own logic, forms, and requirements. Inventory synchronization is unreliable - products are regularly sold that are already out of stock, leading to angry customers, negative reviews, and penalty fees. Shipping addresses are copied by hand, resulting in errors on 5% of orders. Customer notifications are missed. Average processing time is 48 hours instead of the promised 24. During peak season, systems collapse. Personnel costs rise while customer satisfaction drops. Monthly losses from errors, overselling, and customer churn easily reach €15,000 or more.

Our Solution
The reference architecture connects every sales channel to one central order pipeline built on n8n. Shopify, Amazon, and WooCommerce report new orders via webhook — no polling intervals, no overlooked orders.
On arrival, the pipeline immediately reserves the item in the central inventory database (PostgreSQL) and decrements stock on every other channel. The item that just sold on Amazon can't be sold again in the shop — overselling becomes structurally impossible, not just less likely.
The order then runs through the fulfillment track: address validation against the shipping API, label generation, tracking number back to the channel and out to the customer by email (SendGrid, in their language), payment reconciliation against Stripe, receipt to accounting. A routing step picks the optimal fulfillment center based on location, availability, and shipping cost.
If a step fails — payment error, carrier API down, item suddenly unavailable — the order doesn't vanish into the void. It lands in a clarification queue with automatic retries and a Slack alert to a human.
Humans only see the exceptions. Everything else flows through.

What comes out of it
Possible setup, not a packaged product
The figures shown are target values and expected magnitudes for a possible setup – based on industry benchmarks, public studies of comparable setups, and our own tests on a real stack. They are not measured outcomes from a specific customer project; actual results depend on company size, process maturity, and integration depth. We do not offer this setup as a packaged product. We help teams design, automate, and run such processes themselves – through architecture consulting, workshops, and implementation support with n8n. For regulated third-party systems with certification or license requirements (e.g. HIS, gematik, DATEV-certified), we partner with specialized providers.
