What We Cover

Everything your clients need.
Delivered under your name.

From a single-page site to a complex infrastructure migration — we scope it, build it and support it. You own the client relationship.

01

White-label web development

We build it. Your agency delivers it. WordPress, WooCommerce, PHP apps, landing pages — to your spec, on your timeline, under your brand.

WordPress WooCommerce PHP / Symfony Landing pages
02

Managed hosting for your clients

Monitoring, backups, updates, SSL, email — handled. You keep the client relationship and billing. We work behind the scenes.

Cloud hosting Monitoring SSL & backups Email management
03

Automation & CRM integrations

Form → HubSpot → email sequence → Slack. We build it. You present it. No one needs to know the technical work was ours.

04

Technical consultation

Bring us into complex client conversations. Pitch support, scoping, architecture decisions — your background technical expert, invisible to the client.

05

Custom PHP applications

Portals, dashboards, booking systems, membership platforms. PHP/Symfony with real architecture — not a plugin stack that breaks on every update.

SEO & performance audits

White-label technical SEO and Core Web Vitals reports ready to present under your brand. Or we fix the issues — you present the results.

Grow your agency without growing your team.

Every project your clients bring you — we handle the technical delivery. You handle the relationship.

How It Works

Simple, clean, confidential

No bureaucracy. No account manager layers. Direct access to the people doing the work.

1. Partnership call

30 min call. We understand your agency and what projects you'd bring us in for. NDA signed on or before this call.

2. Scope it

Brief us by email or call. We come back with scope, timeline and cost within 48h. You mark it up and quote your client.

3. We deliver

We do the work. Your client sees your agency name only. Deliverables go to you for approval before delivery.

4. Ongoing support

Post-launch hosting and maintenance handled on your behalf. Clients contact your agency — we're the invisible technical layer.

Why Overslep

What makes us a reliable technical partner

NDA on every project

We never contact your clients, reveal who we work with, or use your projects as portfolio without written consent.

Direct communication

Direct line to the person doing the work — not an account manager relaying messages. Faster decisions, fewer misunderstandings.

Honest timelines

If a deadline is tight we say so before you promise it to the client — not after. No surprise delays.

Documented deliverables

Everything we build is documented. You can manage, extend or hand off any project without being stuck with us.

EU-based, bilingual

Lisbon. English and Portuguese. EU timezone. GDPR-aware. Works for agencies in Portugal, Spain, UK or anywhere in Europe.

Simple invoicing

Invoices go to your agency only. You control the pricing, margin and billing relationship with your client.

FAQ

Common questions from agencies

Can you work completely under our agency brand?
Yes. White-label delivery means your client sees your agency name on everything — emails, reports, invoices, communications. We don't exist from their perspective unless you choose to introduce us.
Do you sign NDAs?
Yes. We sign a mutual NDA before any project information is shared. Your client list, project details and technical specifications are confidential. We also don't use white-label projects in our portfolio without written consent.
What languages do you work in?
English and Portuguese, both fluently. Our technical documentation and deliverables default to English. Client-facing materials can be in either language depending on what your client expects.
How do you handle project communication with our agency?
Direct — by email, Slack, WhatsApp or a shared project management tool your agency already uses. We adapt to your workflow rather than asking you to adopt ours.
What's the minimum project size for a partnership?
There's no minimum. We work with agencies that have occasional technical needs as well as agencies with regular monthly project volume. The partnership framework scales to how much — or how little — you bring us in.
Can we use you for hosting and maintenance without web development?
Absolutely. Many agency partners use us purely for backend technical management — hosting, monitoring, updates, email setup — while they handle all the design and front-end work themselves.
