22 ways to deliver more value to your web development clients

Some agencies price a website like it's a one-off build. They scope it, they build it, they hand it over, and then they go looking for the next project. The agencies we see doing well are the ones who worked out that the build is the beginning of the relationship, not the whole of it.

Add-on services are how that works in practice. Some of them are genuinely valuable to the client and take you an afternoon. Some are recurring revenue that keeps your team busy in the quiet months. And a few are things your client will eventually need whether you offer them or not, so you may as well be the one who does.

Three rules we'd apply before pitching any of this:

• Only suggest services that connect to something the client actually cares about. A booking system for a business that doesn't take bookings is just an upsell.
• Bundle where you can. An add-on attached to a build is an easier yes than the same service sold cold six months later.
• Keep the add-on cheaper than the build itself. If your maintenance retainer costs more than the site, something's gone wrong with your pricing.

Here are 22 services worth considering. Not all of them will fit every client. (And honestly we'd probably be suspicious of any agency that tried to sell all 22 to the same person.)

Website functionality services # Direct link to this section

1. A CMS your clients will actually use # Direct link to this section

If your client has to email you every time they want to fix a typo, you've built them a website they can't own. That's bad for them and it's a support burden for you.

Give them a CMS with a real visual editing experience, not a form-filling interface bolted onto a template. CloudCannon gives non-technical editors a Visual Editor that works on the live page, and a Content Editor for blog posts and documentation. Everything stays in Git, so you keep your workflow while they get theirs.

You can also charge for the setup. Configuring collections, schemas, and editable regions properly is real work, and it's the difference between a client who edits confidently and one who breaks their homepage.

2. Digital asset management # Direct link to this section

Clients upload a 12MB photo straight off a phone camera and wonder why the page takes eight seconds to load. Connecting their site to a DAM solves the problem at the source.

CloudCannon connects to a DAM at the organization level, so you can authenticate once and link it to as many client sites as you need. Cloudinary, S3, Cloudflare R2, DigitalOcean Spaces, Google Cloud Storage, Azure Blob Storage, and Tenovos are all supported. Pair it with something like imgix for transformation and delivery and your client stops thinking about image dimensions entirely.

For clients with an existing brand library, this is often the single most appreciated thing you can set up. Their marketing team already has the assets. They just can't get them onto the website.

3. Site search # Direct link to this section

A site with more than about 50 pages needs search, and most small business sites cross that line within a couple of years of publishing blog posts.

Pagefind is free, open source, and built for static sites. It indexes at build time and ships a search UI that works without a server or a monthly bill. It's my default recommendation for anything under a few thousand pages.

Where Pagefind runs out of road is typo tolerance, faceting, and search analytics. Typesense and Meilisearch both self-host for free and have hosted tiers if you'd rather not run the infrastructure. Algolia is the expensive, polished option, and its DocSearch program is free for open source documentation sites. Any of the three sits happily alongside a statically generated site, since you're pushing an index at build time and querying it from the browser.

4. Contact forms and spam prevention # Direct link to this section

Forms are the most common lead-generation tool on any small business site, and they're also a spam magnet. Sell them together.

CloudCannon has built-in form handling with an Inbox for submissions, plus integrations for Zapier, Slack, IFTTT, and Make. On the spam side, we'd reach for Cloudflare Turnstile before reCAPTCHA these days. It doesn't make users identify traffic lights, and it doesn't hand Google another tracking surface on your client's site. hCaptcha is a reasonable alternative if the client has a specific reason to prefer it.

5. Ecommerce # Direct link to this section

Plenty of clients want to sell something without rebuilding their entire site around a store. A static site plus an ecommerce layer handles this well, and it's usually cheaper to run than a full platform.

Snipcart is the one we see most often on CloudCannon sites. You define products in your markup or your data files, drop in a script, and the cart and checkout are handled for you. There's even a Jekyll ecommerce template built for CloudCannon if you want a starting point. Shopify's Buy Button is worth a look for clients who already run Shopify inventory elsewhere, and Stripe Payment Links will cover a client selling a few items or a workshop ticket. For anything with real subscription or fulfilment logic, Foxy handles more complexity than the rest.

The main question to ask up front is inventory size. Ten products and a checkout is a very different project from 2,000 SKUs with variants and stock sync, and you'll want to know which one you're quoting for.

6. Online booking # Direct link to this section

Restaurants, clinics, salons, tradespeople, consultants. A lot of small businesses run their calendar over the phone and lose bookings every time nobody picks up.

For consultants and service businesses, Cal.com is open source, self-hostable, and its embed drops into a static page without a build step. Calendly does the same job with less configuration if the client wants something they can manage without you. For appointment-heavy industries, SimplyBook.me covers staff rosters, resources, and deposits.

Most industries have a specialist tool that already does this well, so unless you have a strong reason, integrate rather than build. If you work in one niche repeatedly, it's worth talking to the platform about a partner or referral arrangement. You're sending them customers either way.

7. Newsletter automation # Direct link to this section

For clients whose business depends on email, connecting the site to their newsletter platform is a small job with a direct revenue link. Sign-up forms, list segmentation, automated post-to-newsletter workflows.

Kit (formerly ConvertKit) suits creators and anyone running sequences. Buttondown is a lightweight, developer-friendly pick, with a clean API and a Markdown editor your client won't fight. Mailchimp is still the default for clients whose accountant already knows the name. All three give you an embeddable form and an API, so wiring one into a static build is an afternoon.

Newsletters pair naturally with analytics reporting, because a client who cares about their list usually wants to know what it's doing.

8. Site internationalization # Direct link to this section

If your client sells across borders or operates somewhere bilingual, translation is a service they'll need eventually.

CloudCannon supports internationalized content, and Rosey is a free open-source option for managing translations on static sites without restructuring the whole project. It runs after your build, so Hugo, Eleventy, Astro, and anything else that outputs static HTML all work the same way. This could be worth pricing as an ongoing service rather than a one-off, since new content needs translating too.

9. AI chat and site assistants # Direct link to this section

The chatbot pitch has changed a lot in the last couple years. What clients want now isn't a decision-tree bot that fails on the third question. It's something that can answer from their actual documentation, product pages, and support history.

Kapa.ai and Inkeep both do this as a hosted service: point them at a docs site or a sitemap, paste in a script tag, and you have an assistant that answers with citations. Kapa is the more accuracy-focused of the two and will say it doesn't know rather than guess. Inkeep is source-available if a client wants to self-host. Either way the setup work is genuinely billable.

The thing to be honest with clients about is maintenance. An assistant trained on last year's pricing page will confidently quote last year's prices. Sell the ongoing content sync, not just the install.

Marketing, SEO, and AI visibility # Direct link to this section

10. SEO audits and Core Web Vitals # Direct link to this section

Technical SEO is the easiest service to sell to a client who has no in-house marketing, because they can see the ranking and they can't see why it isn't better.

Agree a cadence, quarterly or twice-yearly, and deliver an actual report. Fix the technical issues you find. Google Search Console is free and does most of what you need for diagnosis, and Ahrefs or Semrush fill in the keyword research side if the budget stretches.

Don't skip Core Web Vitals. Interaction to Next Paint replaced First Input Delay as a ranking signal back in March 2024, and a lot of sites built before then have never been measured against it. web.dev has the current thresholds. Static sites tend to pass these comfortably, which makes for a good report and an easy conversation.

11. AI search visibility # Direct link to this section

A meaningful share of your clients' potential customers now ask ChatGPT, Claude, Gemini, or Perplexity a question instead of typing it into Google. Some of them never see a search results page at all.

Getting cited in those answers is a different discipline from ranking. It rewards clear structure, factual specificity, content that answers a question directly rather than burying the answer under 800 words of preamble, and machine-readable markup. Practically, that means schema.org structured data, clean semantic HTML, a sensible llms.txt, and content organized so a model can extract a claim without guessing.

This is a genuinely new service line and most agencies aren't offering it yet, which makes it a good differentiator. It also happens to be something static sites are well suited to, because the content is already sitting in the markup rather than being assembled by JavaScript after page load. We've written about why a Git-based CMS makes this easier if you want the longer version.

12. Web analytics # Direct link to this section

Connecting analytics takes twenty minutes. Explaining what the numbers mean, every month, is the actual service.

Google Analytics is free and ubiquitous, but we'd at least mention privacy-focused alternatives like Plausible or Fathom to clients in Europe or anyone who'd rather not add a consent banner just to count pageviews. Both are a single script tag, both are lighter than GA4, and both let you give the client a public dashboard link instead of a login they'll never use.

Monthly reporting is one of the more sustainable retainers you can build, because it's low effort once you've templated it and clients notice immediately if it stops.

13. Paid search management # Direct link to this section

Ad management is a natural fit if you already own the client's landing pages, because you control both halves of the funnel. You can build the page, run the campaign, and actually close the loop on conversion.

Start small. A single well-targeted Google Ads search campaign with a properly instrumented landing page will teach you and the client more than a scattered budget across three networks. Microsoft Advertising is worth testing second, mostly because the competition is thinner and the cost per click usually follows.

14. Branding and digital assets # Direct link to this section

New business owners often come to you with a logo made in Canva and no idea what their brand colors are. Photography, illustration, video, and brand guidelines are all services you can offer directly or subcontract.

If you're a solo developer or a small team without design capacity, build a referral network instead. A standing arrangement with a photographer and a designer you trust means you can say yes to the whole project without pretending you do everything. Referral commissions are normal in this space and worth negotiating up front.

15. CRM setup and integration # Direct link to this section

Any client collecting leads through a form or selling through a store has data going somewhere. Often that somewhere is a spreadsheet.

HubSpot has a free tier that covers most small businesses and an agency partner program that pays. Pipedrive is simpler and better suited to a client who just wants a pipeline they can see. Zoho CRM is the cheap option for a team of three who need it to work and don't care about anything else.

Setting up a CRM and wiring the site into it is a defined piece of work with a clear payoff, and most CRM vendors run partner programs that pay you for the referral. This pairs directly with item 4, since the forms you built are the input.

Development, security, and compliance # Direct link to this section

16. Hosting, domains, email, and CDN # Direct link to this section

The classic bundle. You manage the infrastructure, the client gets one invoice instead of four, and nobody lets the domain lapse because the receptionist who registered it left the company.

CloudCannon hosting includes a global CDN and custom domain support, so the performance side is handled without you standing up infrastructure. Add domain-connected email addresses while you're there. A business still using a Gmail address on their contact page looks less credible than one that isn't, and setting up a professional email signature takes ten minutes.

Some of this is close to free money. Set it up once, bill it monthly, and check in when something needs renewing.

17. Site maintenance retainers # Direct link to this section

Dependencies rot. Frameworks ship breaking changes. A site nobody has touched in three years is a site that won't build when someone finally needs to change the phone number.

A yearly or quarterly maintenance retainer covers dependency updates, build health, broken link checks, and small content changes. Most of the dependency side automates: Renovate and Dependabot will open the pull requests for you, and you bill for reviewing and merging them rather than for noticing they were needed. For agencies running a lot of sites, the CloudCannon CLI and REST API make the rest tractable at scale. You can script the routine checks across every client site instead of clicking through them one at a time.

This is the most reliable recurring revenue on the list, and it's also the thing that stops a client's site quietly dying.

18. Accessibility audits and compliance # Direct link to this section

This one moved from nice-to-have to legal requirement, and a lot of agencies haven't caught up.

The European Accessibility Act has applied to new products and services since 28 June 2025, with services already on the market getting until 28 June 2030. It covers ecommerce, banking, transport, e-books, and consumer digital services, and it reaches companies based outside the EU that sell into the EU market. Micro-enterprises under 10 staff and €2 million turnover are exempt. The technical standard is EN 301 549, which in practice means WCAG 2.1 Level AA. Enforcement has already started, with the first legal actions filed in France in late 2025.

If any of your clients sell to European customers, this is a conversation you should be having. Run an audit, fix what you find, write the accessibility statement they're required to publish, and put it on a review cycle. axe DevTools and Lighthouse will find the obvious failures, and Pa11y will run the same checks in CI so regressions don't ship. Automated tooling catches maybe a third of the issues, though. Keyboard navigation and screen reader testing need a human.

Even for clients with no EU exposure, accessibility work is a straightforward argument. Roughly one in five people has a disability of some kind. That's not a niche audience.

19. Privacy and consent management # Direct link to this section

GDPR, the ePrivacy Directive, CCPA, and a growing pile of state-level US privacy laws all apply to sites that collect data. Most small business sites are non-compliant in ways their owners don't know about.

The service here is an audit and a fix. What's the site loading, what data does it collect, is there a consent mechanism, does the privacy policy match reality. If a banner is genuinely needed, Cookiebot and CookieYes both scan the site and generate the banner for you, and Klaro is the open-source option if you'd rather configure it in a JS file and not pay per domain.

Static sites have an advantage worth pointing out: without a database of user records sitting behind the site, there's a lot less to protect and a lot less to disclose. Sometimes the best fix is removing the third-party script nobody could justify in the first place, at which point you may not need the banner at all.

20. Security testing and SSL # Direct link to this section

SSL should be automatic on every site you build. CloudCannon issues certificates automatically, so there's no reason for a client site to be serving over HTTP in 2026.

Beyond that, larger clients may want periodic penetration testing, dependency vulnerability scanning, and a documented response process. Snyk and GitHub's own security features cover the dependency side, and OWASP ZAP is the free starting point for actual scanning. Static sites reduce the attack surface substantially, since there's no server-side execution and no database to inject into. That's a selling point in itself, and worth saying plainly to a client who got burned by a WordPress compromise at their last agency.

Bonus value-add services # Direct link to this section

21. Business profile and reputation management # Direct link to this section

For local businesses, Google Business Profile is often more valuable than the website for foot traffic. Set it up properly, claim the listing, get the categories and hours right, and add the photos.

Then set up review monitoring so the client knows when someone posts something. BrightLocal handles listing accuracy across directories as well as review alerts, and GatherUp is the better pick if the client also wants to actively request reviews from customers. Responding to reviews well is a skill most business owners don't have, and coaching them through it is a legitimate service. This also feeds back into item 11, because local business information is exactly the kind of structured fact an AI assistant will surface when someone asks for a recommendation.

22. Handoff workshop and documentation # Direct link to this section

The last hour of a project determines how the next year goes. If you hand over a login and disappear, you'll spend the following six months answering the same four questions by email.

Run a proper session. Walk the client's team through the CMS, the analytics dashboard, and anything else they now own. Record it so the person who joins in March can watch it. Write a short document covering the things people forget: where the domain is registered, who to contact about hosting, how to add a new team member.

Before that session, check what your client will actually see when they log in. CloudCannon's Custom Permission Groups and Client Sharing let you scope access to exactly what each person needs, so a marketing hire can update the blog without being able to change the build configuration. It's a much better handoff when the client's first login shows them a clean interface instead of every setting in the app.

Where to start # Direct link to this section

If you're picking two or three of these to add this quarter, we'd start with maintenance retainers, accessibility audits, and AI search visibility. The first pays reliably, the second is becoming a legal requirement your clients don't know about yet, and the third is new enough that offering it puts you ahead of most of your competition.
