For Digital Agencies

Your clients expect award-level UX and bulletproof delivery on commerce, portals, and marketing technology—but keeping every specialist in-house is expensive and uneven. Zelpex acts as a transparent extension of your studio: we join client calls under your brand when you want, follow your Figma and component libraries, and ship production code on the stacks your statements of work promise.

We routinely collaborate on Shopify, BigCommerce, Adobe Commerce, Medusa, headless React and Next.js frontends, CMS builds, custom integrations, and the cloud and DevOps glue that makes launches boring in the best way. You retain creative leadership; we own technical risk, estimates, and QA discipline.

  • White-label or co-branded delivery with clear communication protocols
  • Fixed-scope SOWs or retainer pods for velocity and predictability
  • Design-to-code fidelity with accessible, performant frontends
  • Post-launch SLAs, monitoring, and iteration so your clients renew
01

Partner quietly

We sign NDAs and MSA frameworks that mirror how you work with freelancers or offshore partners—then align on tooling, repos, and design tokens so handoffs stay frictionless.

02

Estimate honestly

We review your creative and content assumptions, call out technical risks early, and give ranges you can defend to clients—with options scoped as good, better, best.

03

Ship together

Developers join your standups or async rituals, push through your Git workflow, and document releases so account teams always know what shipped and what is next.

04

Stay invisible when it counts

We support launches, war rooms, and post-release stabilization under your banner. When the project wins an award, your name stays on the tin—we are fine cheering from backstage.

Agency leads ask

Only if you want them to. Most engagements are white-label. We use your email domains, meeting links, and ticket boards unless you prefer a transparent trio model with the client.

We help you document impact in plain language, propose options with time and cost deltas, and protect your margin. Change control is part of the partnership—not an awkward surprise for your PMs.

Yes. Many agencies keep a Zelpex pod for security updates, platform upgrades, campaign landing pages, and small enhancements so your core team stays focused on new pitches.

Why agencies keep us on speed dial

We make your proposals believable: credible architecture, realistic timelines, and engineers who can join a creds meeting without sounding like a black box.

When briefs touch AI data services, blockchain, cybersecurity, or complex cloud topology, you can still answer “yes” to the RFP—backed by specialists who have shipped it before, not slides that promise magic.
