Integrations and API · Retail & e-commerce
Integrations and API development for retail and e-commerce stores.
Every business runs on a handful of systems that were never designed to talk to each other, so people become the integration: copying a booking into the calendar, a lead into the CRM, an order into accounting. We build the connections that remove that work, using each system's official API, with logging and alerts so nothing is silently dropped. Working remotely from our Providence, RI studio, we scope, build, and monitor integrations for businesses across North America. Shoppers judge an online store by the product page, not the homepage. Photos must load instantly, price and shipping should be visible before the cart, and checkout should accept the payment method already on the phone. We build retail and e-commerce sites where catalog, inventory, and checkout run as one connected system rather than three plugins fighting each other. For retailers and online stores, integration keeps inventory in sync between the POS and the website, pushes orders to your fulfillment or shipping tool, syncs customers and purchase history to your email platform for segmentation, and posts daily sales to accounting. Marketplace channels such as Amazon or Etsy can draw on the same inventory count.
Quick answer
Integration work for retail and e-commerce stores connects your website to the CRM, scheduler, accounting, and inventory systems you already use, through their official APIs, with retries, logging, and alerts so nothing is silently dropped. GEO Marketing Group builds custom integrations and APIs starting around $8,000, typically $14,000, working remotely from Providence, RI.
What it includes
What integrations and API builds include for retail and e-commerce stores.
Two-way sync with CRMs, schedulers, accounting, inventory, and marketing tools through their official APIs
Webhook handlers that react to events in real time, with retries and a dead-letter log
A private or partner-facing REST API with authentication, rate limits, and documentation
Scheduled jobs for imports, exports, and reconciliation against the source of truth
Field mapping and validation rules you can review, with an audit trail of every record moved
Monitoring and alerts when a connection fails, so silent data gaps do not accumulate
Connects to the tools retail and e-commerce stores already use.
Integrations and API builds earn their keep when they stop double entry. These are the integrations we most often scope for retail and e-commerce stores; if your stack is different, we map it in discovery.
Why retail and e-commerce stores reach for this.
Product pages load slowly on phones
Uncompressed images and a heavy theme turn a browsing session into a wait, and shoppers rarely wait for a store they have never bought from.
Inventory is wrong online
The website sells what the shop sold yesterday, and every oversold order costs a refund, an apology, and a review you did not want.
Checkout asks for too much
Forced account creation, a shipping cost revealed at the last step, and no wallet option end the purchase one screen before the sale.
Integrations and API builds start from $8,000. Every project is quoted to its scope.
