Are your prices netto or gross?

All prices for Kolos Digital B2B services are quoted netto in EUR. German VAT (19% USt) is added where legally applicable, and invoices are issued in accordance with German commercial accounting standards.

What payment milestones do you use for development projects?

For fixed-scope builds (landing pages, business sites, e-commerce), we operate on a 50% deposit upon contract signing to secure production capacity, and the remaining 50% upon final delivery, testing, and production deployment.

What is the Rule of Scope for change requests?

Every written Angebot specifies exact pages, features, and revision rounds. Anything outside the agreed scope is quoted transparently as a change request before work begins, ensuring zero surprise costs.

How does pricing work for AI agents and API costs?

We clearly separate one-time engineering setup, monthly maintenance, and direct third-party API usage (OpenAI, Anthropic Claude, telephony). You maintain direct control and transparency over actual API consumption.

Netto B2B Pricing & German Taxes

All prices quoted are netto in EUR. Invoices are issued through German-compliant commercial accounting with official tax ID and line-item scope breakdown. Standard German VAT (19%) is applied where legally mandatory.

Payment Milestones

Fixed-price builds: 50% deposit upon contract signing to reserve production dates; 50% upon deployment and client sign-off. Monthly retainers are billed in advance on the 1st of each calendar month.

The Rule of Scope (Angebot Disziplin)

Every formal proposal clearly lists pages, languages, integrations, revision rounds, and criteria for completion. Any additions outside scope are quoted transparently as an approved change request before execution.

API & Usage Separation

For AI assistants and telephony systems, setup engineering and monthly SLA maintenance are billed by Kolos Digital, while actual API usage (OpenAI token rates, SIP carrier minutes) is billed directly to you at wholesale cost.

Frequently Answered

Questions about pricing & contracts.

Direct answers to the most common questions before booking a discovery call.

How long does a website build take?

A focused landing page takes 1 to 2 weeks from brief to deployment. A bespoke 5–8 page business site takes 3 to 5 weeks. Complex multilingual or e-commerce projects take 5 to 8 weeks with clearly defined staging sprints.

Can I start with a single build and add SEO or AI retainers later?

Yes. Many clients start with a Foundation Business Website (€3,200), test market traction, and then seamlessly activate Website Care (€190/mo) and Local SEO (€590/mo) to scale customer acquisition.

What is included in the Website Care retainer (€190/mo)?

Website Care includes 24/7 uptime monitoring, daily automated cloud backups, SSL certificate maintenance, security patches, and up to 60 minutes of small text/image updates each month.

Do I own 100% of the website code and assets upon final payment?

Yes. Upon receipt of the final invoice payment, full commercial exploitation rights and unencrypted source code are transferred directly to your company. You are never locked into proprietary agency platforms.

What is the minimum contract period for SEO retainers?

Local SEO & Google Business Profile has a minimum 3-month commitment, as search indexing and Map Pack velocity require consistent citation building. SEO Growth has a 6-month minimum commitment for substantial organic ranking gains.
