Illustrative case: Online marketing agency, Rotterdam — 2026

Fixed white-label sprint capacity under the agency’s brand

Twenty-four sites in twelve months, and the client only ever saw their name.

Sprints · 24 · 0 · 3.4 wks · 31 Plate 13 · SPRINTS
  • 24 sites and stores in 12 months
  • 0 missed deadlines toward end clients
  • 3.4 wks average lead time per site
  • 31 sites in the maintenance portfolio

01 — The challenge

The agency kept winning clients who wanted a website or store alongside marketing. Freelancers were unpredictably available, an offshore partner misread the designs and margin evaporated in hourly billing. Client deadlines became a risk.

The requirement: fixed prices they could mark up, pixel-perfect builds to their designs, full invisibility toward the end client and maintenance they could sell as a subscription.

02 — Our approach

We agreed on four days a week of capacity with priority scheduling, a shared project channel and a fixed price list per site type: Launch, Growth and Flagship. Per project the agency delivers Figma designs and a brief; within two business days there is a fixed price and a date.

To build pixel-perfect, we turned their Figma tokens into a shared design system in code, reusable across all client sites. Every site gets a staging environment, a Lighthouse report and a handover video in the agency’s brand.

We bundled maintenance into a portfolio plan with one dashboard for all client sites: updates, monitoring, backups and change hours the agency bills through.

03 — The solution

In twelve months: 24 delivered sites and stores (Next.js, headless WordPress, Webflow, Shopify), an average of 3.4 weeks per site, zero missed deadlines. The agency presents us internally as “our technical team” and keeps the client relationship entirely its own.

The maintenance portfolio grew to 31 sites with a monthly margin for the agency that comfortably covers the capacity agreement.
