WordPress Development Services: What's Included and What It Costs (2026)

A quote for 'WordPress development services' can mean a $500 theme install or a $40,000 custom platform, because the phrase bundles five or six distinct services that agencies price apart once you ask. Vendors rarely itemize by default, since a single number is easier to sell than a breakdown that invites comparison shopping. Knowing what each piece costs on its own makes any quote easier to read, and easier to negotiate.

Design and theme development

Theme work ranges from a child theme customization on an existing template to a full build from scratch, and cost tracks that range: $1,500 to $40,000+ depending on which one you need. Most US small businesses land at $5,000 to $15,000 for a custom theme, with builds taking 4 to 16 weeks from kickoff to launch. A simple site using a pre-built theme with light customization runs $500 to $5,000, and that gap is almost entirely the difference between adjusting an existing design and writing one from a blank file.

Plugin development and integrations

None of these three line items appears in a base website-design quote by default. If your project needs a booking system tied to your calendar, a CRM sync, or a custom-built plugin for something WooCommerce and the standard plugin directory do not cover, budget for it apart from the base build and ask the agency to price it as its own scope item, not a vague percentage add-on.

WooCommerce and ecommerce setup

WooCommerce runs 93.7% of WordPress ecommerce sites and holds close to 33.4% of the global ecommerce market, with over 4.3 million active stores. Store setup covers product catalog structure, payment gateway configuration, shipping and tax rules, and integration with as many as 4,600 WooCommerce-specific plugins, and a standard brochure-site quote excludes all of it. Agencies price it as its own line item, inside the same $5,000 to $30,000 range as a custom theme, depending on catalog size and payment complexity. A 50-product store and a 5,000-SKU catalog with variable shipping rules sit at opposite ends of that range for good reason.

Migration, SEO setup, and technical work

• Site migrations from another CMS or an older WordPress install, priced by page count and how much custom functionality has to survive the move intact.
• On-page SEO setup, including schema markup, redirect mapping, and Core Web Vitals work, which agencies now bundle since search rankings depend on both design and content structure.
• Security hardening, worth asking about given that plugins account for 91% of the 11,334 new WordPress vulnerabilities logged in 2025.

Ongoing maintenance

Maintenance is where most quotes stop mentioning numbers, but it deserves a line item like everything else in this list. WordPress maintenance costs range $30 to $5,000+ a month across the market: $50 to $200 a month covers a small-business site with updates, backups, and monitoring, while a WooCommerce store runs $500 to $3,000 a month because downtime costs revenue every hour it stays down. If a quote skips this line, ask for it before you sign, since the gap between a $50 and a $250 plan comes down to whether a developer reviews the site each month or a script runs updates unattended.

Break any quote into these pieces before comparing it against another agency's number. Two quotes at $8,000 can cover very different scopes, one a brochure site with light SEO, the other a WooCommerce build with custom integrations. Our WordPress development team itemizes each of these services before a project starts, so you know what you are paying for at every stage.
