E-commerce Connectors & Integrations
Custom connectors that link your store to shipping, accounting, marketplaces and marketing tools. Orders, tracking numbers and customers move on their own.
AD Software builds connectors, apps and custom software for online stores that have outgrown copy and paste. Your store, shipping, accounting and suppliers, finally talking to each other.
Platforms we've built on and connected
What we do
From a single connector to a full custom app, we scope it, build it, host it and keep it running, so you are not the integration.
Custom connectors that link your store to shipping, accounting, marketplaces and marketing tools. Orders, tracking numbers and customers move on their own.
Daily price and inventory updates pulled from supplier files, portals and APIs, so your listings stop selling what your supplier ran out of yesterday.
Dashboards, admin tools, in-store screens and team apps built around how your business already works, not how a template thinks it should.
Scheduled jobs, alerts, reports and AI assistants trained on your own products and policies. The repetitive work gets done while you are doing something else.
How it works
Describe the task you keep doing by hand, and the systems on each side of it. An email is enough to start.
You get a plain English plan and a fixed price before any work begins. If an off the shelf tool will do it for less, we say so.
We build against your real data and test it alongside your current process, so nothing switches over until it is proven.
We host and monitor it, or hand over the code and documentation. When a platform changes its API, we fix it.

About AD Software
AD Software is run by Adam DePass, who has operated a Canadian online and retail store since 2003. The tools on this page began as fixes for that business: orders retyped into a shipping account, store screens nobody had time to update, customer questions piling up after hours.
That is the difference. We are not guessing at how an online store works from the outside. We have lived the month end, the oversold product and the platform update that breaks everything on a Friday, and we build software that expects them.
AD Software is the sister company of AD Promo, and works the same way: one point of contact, clear pricing, and work that shows up when we said it would.
Most small businesses do not need more software. They need the software they already pay for to talk to each other.
The idea behind AD Software
What we connect
A few of the systems and jobs we get asked about most. Not on the list? Ask anyway. If the data can be reached, it can usually be moved.
Common questions
A custom connector is a small piece of software that moves data between two systems that do not talk to each other on their own, for example sending new orders from your online store to your shipping account, or updating your product prices from a supplier's file every morning. It runs in the background on a schedule or the moment something changes.
If an existing app does exactly what you need, use it, and we will tell you so. Custom work makes sense when no app exists for your platform, when the existing one is unreliable or missing a feature you depend on, or when per task fees add up to more than owning the connector outright.
We have built on Shift4Shop, WooCommerce, Stallion Express, Doofinder, AWIN, Mailchimp, Google Analytics, Google Search Console and Google Sheets. Shopify, QuickBooks, supplier portals and most other systems with an API, a data feed or an export can be connected too.
Every project gets a fixed quote before any work starts, so the price you approve is the price you pay. A single connector is a small project, not an enterprise contract. Send us a description of the task and the two systems involved and we will reply with a price.
It depends on the systems involved. A single connector between two platforms with good APIs is a short project, while a full custom app takes longer. Your quote includes a timeline, and we test alongside your current process before anything switches over.
Your choice. We can host and monitor it for a flat monthly fee, which includes fixing it when a platform changes its API, or we can hand over the code and documentation for you to run on your own server.
No. Online stores are where we have the most experience, but the same skills apply to any small business with systems that do not talk to each other. We also build custom web apps, internal tools and AI assistants. We are based in the Greater Toronto Area and work with clients across Canada and the United States.
Describe the task and the systems involved. We will reply with questions or a fixed quote, usually within one business day.
