What a custom agent looks like inside an online retail or DTC brand — the ten roles in your language, and what each plugs into in a business running Shopify or BigCommerce alongside a helpdesk, a 3PL and an ad stack.
last reviewed
An e-commerce business generates more data than any other kind of small company and uses less of it, because the people who could act on it are answering tickets and chasing a shipment. The store platform is excellent at selling. What it does not do is reconcile what three ad platforms claim against what actually landed, catch the supplier price change that quietly ended your margin, or answer the same shipping question four hundred times a week.
The honest version of "does it integrate with my software." These are the systems this industry actually runs on, and what each one means for a build.
The system of record for products, orders, customers and inventory, with excellent, well-documented interfaces that make almost anything reachable.
Where tickets arrive across email, chat and social, and where the same handful of questions consume most of the team's time.
Warehouse and shipping partners whose systems determine what you can actually promise a customer about delivery.
Lifecycle messaging, where segmentation quality determines revenue and where most brands use a fraction of the data they hold.
Meta, Google, TikTok and the rest, each reporting conversions on its own terms, which never add up to what the store recorded.
Reorder points, supplier lead times and landed cost, frequently maintained in a spreadsheet that is always slightly out of date.
Amazon, Walmart and others with their own fee structures, inventory pools and reconciliation problems.
A cost center that is also a retention opportunity, and usually handled entirely manually.
Each of these is a real build, not a feature of a product you already pay for. Follow one through to see how it works in general.
Nothing you are owed gets dropped.
Whatever arrives, in whatever format, becomes a clean record.
Writes the recurring document from your own past work.
Knows what expires, renews or comes due — and says so first.
Answers from your own records, not from the internet.
The conversation becomes the record, without anyone typing it up.
Assembles the recurring report from systems that do not talk.
Matches two sets of records and queues only the exceptions.
Two systems that do not talk, now talking.
Applies your rules, escalates only what needs judgment.
If that is a job in your business, the next step is half an hour on a call. Bring whatever you know about the volume — how many a month, who owns it now, which systems it touches. That is enough to scope it properly and quote it flat before anything starts.
Everything in this library is built to order rather than bought off a shelf — and whatever I build, I host and maintain. The rest of the library is here.
