When your Shopify or WooCommerce store, your marketplace listings, and your accounting all live in separate silos, small gaps turn into oversells, refunds, and late shipments. As a San Antonio agency, MultiGen Online Marketing builds Custom Business Technologies that connect those pieces into one dependable workflow.
What We Build for E-Commerce & Retail
Inventory Sync Across Channels
One source of truth for stock. Sell an item on your website, Amazon, or in-store and every channel updates in real time, so you stop overselling and stop hiding sellable inventory.
Order Management Automation
Route, tag, and fulfill orders automatically. Rules handle the routine cases and flag the exceptions, so your team is not copying every order between systems by hand.
Store, Accounting & Shipping Connected
We link your store to QuickBooks, your carriers, and your 3PL through clean systems integration so sales, invoices, and labels stay in step without manual re-entry.
Customer Data Unification
Bring every order, ticket, and email into one customer view. No more guessing who bought what when a shopper reaches out across two storefronts.
Post-Purchase & Win-Back Flows
Automated review requests, replenishment reminders, and lapsed-customer offers driven by real order history through targeted business process automation.
Sales & Inventory Dashboard
One screen for revenue, best sellers, low stock, and returns across every channel, so you can make buying and pricing calls from current numbers.
Sound Familiar?
- You have oversold an item because two channels showed different stock counts.
- Someone on your team re-keys orders into your shipping and accounting tools every day.
- You cannot tell which products actually make money until you export three reports and merge them.
- A repeat customer emails and no one can quickly see their full order history.
- Your apps almost connect, but the last mile still runs on spreadsheets and copy-paste.

Do you work with Shopify and WooCommerce?
Yes. We build on top of Shopify, WooCommerce, and most major carts, and we connect them to the marketplaces, accounting, and shipping tools you already use.
Can you sync inventory across more than one sales channel?
That is one of the most common projects we take on. We create a single source of truth for stock so your website, marketplaces, and store locations all reflect the same counts.
Will this replace the tools I already use?
Usually not. We connect and automate around your current stack so the pieces work together, and we only replace a tool when keeping it would cost you more than it saves.
How long does an e-commerce project take?
It depends on scope, but most integrations and automations go live in a matter of weeks, rolled out in stages so your store keeps running throughout.
