FAQ
Does Zest work completely white-label?
Yes. We operate as a silent technical delivery partner under legally binding, bilateral non-disclosure agreements (NDAs). We use unbranded Git commits (or your agency’s domain handles), integrate directly into your internal communication tools (Slack, Teams), and never contact your end clients. Your agency maintains 100% ownership of the client relationship.
Can Zest integrate directly into our agency’s project management tools?
Yes. We natively integrate into Jira, Monday.com, ClickUp, Asana, Basecamp, Notion, Trello, Azure DevOps, Slack, Microsoft Teams, and Google Chat. We adapt completely to your agency’s existing sprint schedules, ticket formats, and delivery ceremonies.
What gross margins can an agency expect by partnering with Zest?
Most agency partners protect 50% to 70% gross margins on their technical development and SEO offerings. By leveraging our Ahmedabad engineering center while billing domestic rates in the UK, Australia, UAE, or US, agencies significantly increase profitability without incurring permanent payroll overhead.
How quickly can an agency onboard a dedicated developer pod?
Standard dedicated pods can be onboarded, briefed, and active in your agency’s workspace within 48 to 72 hours of NDA and agreement execution.
Can Zest work directly with our in-house UI/UX design team?
Absolutely. Our senior front-end engineers work directly from Figma, Adobe XD, or Sketch design files, reviewing component specs, autolayout variables, and breakpoint logic before writing code to ensure pixel-perfect fidelity.
Do you build Shopify themes using apps or custom Liquid code?
We prioritize native Liquid, CSS, and lightweight JavaScript over third-party apps wherever possible. Building features natively into the theme code eliminates recurring monthly app fees, prevents stylesheet conflicts, and ensures sub-second page load times.
