How to Choose the Right Webflow Agency in 2025: 10-Point Checklist

Published July 2025 • 9 min read

Why a specialised Webflow agency beats a generic dev shop

Webflow’s visual canvas, native CMS and built-in hosting mean faster turnaround and fewer plugins, if your team knows the platform inside out. A generic agency might treat Webflow like another WordPress theme. A dedicated Webflow partner will leverage Variables, Logic, Memberships and server-side integrations to deliver a faster, more scalable site. This checklist helps you separate true experts from slick sales pitches.

1 Confirm Webflow Expert or Enterprise certification

Ask for their public Expert profile. Bronze tier proves at least five paid Webflow projects; Gold and Enterprise tiers require audits by Webflow’s internal success team. No badge? Proceed with caution.

2 Review live Core Web Vitals scores

Pull https://web.dev/measure reports for 2–3 of their recent launches. A credible agency will hit >90 on mobile LCP and INP. They should explain how they optimise images, fonts and third-party scripts.

3 Ask for a transparent pricing model

Beware of “it depends” quotes. A mature Webflow agency offers tiered packages (Starter, Growth, Enterprise) or a line-item SOW with hours per task. Look for:

• Discovery & wireframes
• Design & animations
• CMS setup & migrations
• QA, accessibility & performance
• Training + 30-day support

Flat-rate by page count often hides overruns; milestone billing aligns incentives better.

4 Dig into their design-to-build workflow

Do they start in Figma, then rebuild from scratch in Webflow, or design inside Webflow to save time? Pros have a component library and Variables token set ready, ensuring brand consistency and easy future edits.

5 Verify SEO & accessibility expertise

Checklist:

• Semantic HTML5 structure (header, main, nav, footer)
• WCAG 2.2 focus states and ARIA roles
• JSON-LD schema for articles & products
• Automatic IndexNow pings on publish

Request the Lighthouse a11y score for their last build, aim for 90 +.

6 Confirm integrational capabilities

Common 2025 stack:

• Make.com or Zapier for CRM sync
• Stripe or PayPal for e-commerce
• Memberstack / native Memberships for gated content
• Server-side tagging via Cloudflare Workers

Your agency should demo at least one live integration similar to your needs.

7 Understand their hand-off & training approach

Best-in-class partners deliver:

• Recorded Loom walkthroughs of key pages
• An editor-only manual for your marketing team
• A staging URL for future experiments

Bonus points for a style guide page in the project, showing Variables and component usage.

8 Post-launch support SLA

Things break browser updates, analytics scripts, your own content editors. A pro agency offers a 30-day bug-fix window and optional retainer (4-20 hours/month) for iterations, performance audits and new features.

9 Read third-party reviews

Check Clutch, Google Business and Webflow community forums. Flag patterns: missed deadlines, poor communication, hidden fees.

10 Evaluate cultural & timezone fit

Weekly stand-ups at 3 am your time will kill momentum. Ask which project management tool they use (ClickUp, Asana, Trello) and assess responsiveness during the sales phase, it’s the best predictor of delivery cadence.

Key takeaways

Follow this checklist and you’ll hire a Webflow agency that ships on time, on brand and on budget turning your next site launch into a growth engine instead of a headache.
