Why ecommerce IT is its own thing
Online retail businesses live or die by uptime and integration reliability. The site itself, the payment gateway, the inventory sync, the email service provider, the supplier portal, each is one outage away from blocking orders. The IT setup that supports this is fundamentally about making sure all of it stays connected and you find out about problems before customers do.
Most retailers I see have a website built well by a developer or agency, integrations that worked the day they went live, and no ongoing IT operations layer underneath. When something breaks (stock sync, payment gateway, email deliverability), it gets noticed by customers first.
What my work for online retailers typically covers
Integration monitoring. The connections between the ecommerce platform, the warehouse system, the accounting system, and the email service provider, monitored, with alerts when something stops flowing, so the founder doesn’t find out from a customer complaint.
Email deliverability and authentication. SPF, DKIM, DMARC properly configured for both transactional and marketing email. Sender reputation matched to platform expectations. The kind of work that lifts campaign performance and reduces “my email never arrived” support tickets.
Identity and access controls. MFA on every system that touches customer or financial data, conditional access on admin accounts, proper offboarding when someone leaves. Most small retailers have admin credentials shared between three people; tightening this up is usually a quick win.
PCI fundamentals. The IT-side controls PCI requires, network segmentation, MFA, logging, vulnerability scanning. Documented properly so you have evidence you can show your acquirer or card processor when they ask.
Documentation and operational handover. Most ecommerce businesses are dangerously dependent on the founder knowing how everything fits together. Getting that into proper documentation, runbooks, integration diagrams, vendor contact lists, means the business survives a holiday, an illness, or eventually a hire.
