The Quote Looks Reasonable. Then the Bills Start.
A WordPress agency quotes you $4,000–$8,000 for a custom site. It sounds fair. You sign, they build, you launch.
Then the hosting invoice arrives. Then the plugin renewal emails. Then the site gets slow and you need someone to fix it. Then, if you're unlucky, the site gets compromised.
None of this was in the original quote. Here's what to ask about before you sign.
Plugin License Costs
Most professional WordPress sites depend on paid plugins — for page building, forms, SEO, security, caching, booking systems, and more. The agency includes these in the build. What they often don't tell you is that the licenses renew annually and the cost falls on you after year one.
Codeable's 2026 pricing analysis puts a typical business plugin stack at $200–$1,000/year across common line items:
- SEO plugin (Yoast Premium, Rank Math Pro): $99–$229/year
- Security plugin (Wordfence, Sucuri): $199–$499/year
- Forms (Gravity Forms, WPForms): $59–$259/year
- Page builder (Elementor Pro, Divi): $59–$199/year
- Backup plugin (UpdraftPlus Premium, BlogVault): $70–$120/year
Ask your agency directly: which paid plugins will my site depend on, and what are the annual renewal costs?
Hosting Upgrade Costs
Shared hosting at $3–$10/month is inadequate for a business site that needs to load fast, stay secure, and handle real traffic.
Managed WordPress hosting that actually delivers performance — Kinsta and WP Engine being the two most common — starts at $35/month per site according to their published 2026 pricing. That's $420/year at entry level, and scales with traffic. A business site receiving meaningful traffic often lands at $600–$1,200/year.
Some agencies include hosting in their quote. Many don't. Ask directly: what hosting do you recommend, and what does it cost per month after launch?
Maintenance and Update Costs
WordPress requires ongoing maintenance. Core updates, plugin updates, theme updates — each one needs to be tested to make sure it doesn't break something.
Codeable's 2026 market analysis puts the WordPress maintenance range at $30/month (automated-only) to $5,000+/month (enterprise). For a business site with real stakes, realistic professional maintenance sits at $140–$500/month — $1,680–$6,000/year — for someone to keep the site updated, tested, backed up, and monitored.
If you don't pay for maintenance, the updates don't happen. And outdated plugins are the number one entry point for WordPress compromises.
Security Incident Costs
This is the hidden cost that hurts the most.
Patchstack's State of WordPress Security 2026 report documented 11,334 new WordPress vulnerabilities discovered in 2025 — a 42% increase over 2024. 91% of those vulnerabilities were in plugins, not WordPress core itself. The median time from vulnerability disclosure to active exploitation is 5 hours.
When a site gets compromised, Codeable's 2025 recovery data puts remediation at $200–$2,000+ depending on severity. A Melapress industry survey cited by Codeable found that 64% of WordPress professionals had experienced a breach — most on sites without structured maintenance.
What's not included in the remediation invoice: the SEO damage. If Google detects malware and blacklists the site, recovery takes time. For a business that generates leads through organic search, that ranking gap is a real revenue event that never appears as a line item anywhere.
Performance Optimization Costs
WordPress sites tend to slow down over time. Plugins accumulate. The database grows. Images are added without optimization. Caching configurations drift.
Colorlib's 2026 site speed data puts average desktop page load at 2.5 seconds and average mobile at 8.6 seconds across all websites — and only 33% of websites pass all three Core Web Vitals. Google's own research found that 53% of mobile visits are abandoned when pages take longer than 3 seconds to load.
A performance audit and optimization typically costs $500–$2,000, and needs to be repeated as the site evolves.
The Rebuild Cost
Industry research puts WordPress site lifespan at 2–3 years without consistent maintenance, extending to 4–5 years with proper care. After that, plugins conflict with each other, the theme becomes outdated, the original developer is no longer available, and the codebase becomes difficult to work with.
The $5,000 site that seemed like a good deal now costs another $5,000–$8,000 to rebuild. And the cycle starts again.
What to Ask Before You Sign
- Which paid plugins will my site depend on, and what are the annual renewal costs?
- What hosting do you recommend, and what does it cost per month after launch?
- Do you offer a maintenance retainer, and what does it cover?
- What happens if my site gets compromised — is cleanup included or billed separately?
- Who owns the site, the CMS configuration, and all the assets when the project is complete?
A professional agency will answer all of these clearly and upfront. If the answers are vague, that's information too.
A Different Approach
We build on Next.js specifically because it eliminates most of these hidden costs. No plugin licenses. Lower hosting costs on Vercel ($20/month on the commercial Pro tier). A smaller security attack surface because there's no plugin ecosystem and no admin panel exposed to the public internet. Performance built into the architecture rather than bolted on afterward.
It's not free of recurring costs — dependencies still need updating, and framework upgrades are real work. But the structural burden is meaningfully lower than WordPress, and the ceiling on what the site can do is higher.
