Automation for ecommerce and multi-channel retail
Heavily automated at the storefront, and starved of it everywhere behind. The problems start the moment an order leaves the checkout.
What a multi-channel inventory sync build looks like6 steps, 1 decision
- 01Order placedOn any channel you sell through
- 02Stock decrementedOne position, not one per channel
- 03Cover below threshold?Yes, purchase order raisedNo, carry on
- 04Pushed everywhereEvery channel updated within seconds
- 05Fulfillment routedOn stock, location and cost
- 06Two channels disagreeFlagged before it oversells
Each one is priced on the pricing page. Automations start at $499, or bundle into a package. The detail is below.
01Multi-channel inventory sync
The defining problem of this sector. You sell the same SKU on Shopify, Amazon and a marketplace. Stock is one pool. Each channel believes it owns it. Oversell on Amazon and you take a metrics hit that costs more than the order.
What we build: a single source of truth for available quantity, with allocation rules per channel, buffer stock to absorb sync latency, and near-real-time updates on every movement rather than periodic pushes.
Why it is the most expensive build here: it is genuine two-way sync with race conditions. Two orders landing on two channels in the same second is a real event, not a hypothetical. Conflict rules, idempotency and reconciliation are the majority of the work. See why automations break.
Multi-channel inventory is a mature software category. If your requirements are ordinary, an off-the-shelf product will beat a custom build on cost and reliability, and we will say so. A build makes sense when you have unusual allocation logic, a warehouse system with no connector, or a product configuration those tools cannot represent.
02Order routing and fulfillment
Orders routed to the right fulfillment location by stock position, destination and service level; split shipments handled where a single location cannot fulfill; and dropship lines sent to the supplier automatically with tracking flowed back to the customer.
03Supplier purchase orders and reordering
Reorder points calculated from velocity and lead time rather than from a fixed threshold, draft POs generated for approval, supplier confirmations parsed back in, and expected-arrival dates updated so the reorder logic stays honest.
Kept deliberately conservative: POs are drafted, never sent automatically. This is a build where an error spends real money.
04Returns and RMA handling
Return requests validated against order history and policy, labels issued, the customer kept informed, inbound receipt matched to the RMA, and refund or replacement triggered on inspection outcome. Restocking decisions routed by condition.
Frequently the worst manual process in a growing DTC business, and the one customers judge hardest.
05True margin reporting
Revenue joined with landed product cost, channel fees, payment processing, shipping actuals, discounting and returns, per SKU, per channel and per order.
What businesses discover: which SKUs and which channels lose money once fees, shipping and returns are counted. Marketplace fees plus a 20% return rate can turn a healthy-looking gross margin negative, and most sellers do not have this view.
06Customer service order context
Every support ticket enriched on arrival with order history, shipment tracking, return status and lifetime value, so the agent starts with the answer instead of four browser tabs. See customer support automation.
07Review and post-purchase sequences
Review requests timed to actual delivery rather than to order date, suppressed for orders with an open support ticket or return, and differentiated by product category.
What we will not build: review gating, or generated review content. See what we refuse to automate.
The systems you probably have
| Layer | Common tools | Integration reality |
|---|---|---|
| Storefront | Shopify, WooCommerce, BigCommerce | Shopify's API is excellent; WooCommerce depends on plugins |
| Marketplaces | Amazon, eBay, Etsy, Walmart | Amazon SP-API is powerful and genuinely awkward; budget for it |
| Shipping | ShipStation, EasyPost, Shippo | Good APIs, straightforward |
| Warehouse / 3PL | Varies enormously | The usual weak link. Many are EDI or SFTP only |
| Email / SMS | Klaviyo, Attentive | Good APIs and webhooks |
| Accounting | Xero, QuickBooks | Fine; watch multi-currency and fee treatment |
Two things to flag on cost. Amazon's SP-API has rate limits and an approval process that adds real time to a build. And 3PL integration is the most common place a quote moves, because "our 3PL has an API" and "our 3PL emails a CSV twice a day" are very different projects. Establish which before anyone quotes.
What we would do first
Margin reporting, then returns. Margin reporting is comparatively cheap, carries no operational risk, and frequently changes what the business does next. There is little point automating fulfillment for a channel you should exit. Returns second, because it is usually the worst manual process and the most visible to customers.
Inventory sync is the biggest prize and we would generally not make it the first build. It is the most expensive, the most technically demanding, and the one most likely to be better solved by buying software.
Know your true margin per channel?
Most sellers do not. It is one of the cheaper builds here and the one that changes the most.
