FAQ
Frequently asked questions
We integrate Stripe for subscription management, including monthly/annual plans, trials, upgrades, downgrades, prorations, and invoicing. We handle all payment scenarios and edge cases.
Yes. We build flexible billing systems that allow you to add new plans, change prices, and modify features per tier. Changes can be made through admin dashboard or code updates.
We select controls such as row-level security, tenant-aware authorization, and separate schemas based on the risk model. Isolation is verified with boundary and authorization tests; no architecture makes security absolute.
Yes. We implement metered billing where customers pay based on usage (API calls, storage, users, etc.). We track usage and bill accordingly through Stripe.
We build white-label capabilities allowing customers to customize logos, colors, domains, and branding. Enterprise clients can have fully branded experiences.

Delivery considerations for your region
Data and risk discovery (Germany)
Privacy, security, residency, and regulatory requirements differ by workflow. We document the applicable data flows, roles, retention needs, and control owners before recommending an architecture.
The resulting proposal lists the controls and evidence that are actually in scope. It is not a generic compliance, certification, or legal-assurance promise.
- Map data sources, destinations, roles, and sensitive fields
- Record access, retention, logging, and deletion requirements
- Identify required security or procurement evidence before contracting
- Use an NDA or DPA only when the parties mutually execute it
Working model (Germany)
Exact live-overlap hours, response expectations, meeting windows, and escalation contacts are confirmed in the proposal for each engagement.
Written decisions, scoped milestones, and asynchronous updates reduce unnecessary meetings without implying an unagreed service level.
- Proposal-specific overlap and meeting windows
- Named owners for decisions and blockers
- Written scope, assumptions, and change decisions
- Milestone cadence agreed before kickoff
Commercial setup (Germany)
The contracting entity, proposal currency, invoicing cadence, payment terms, intellectual-property terms, and required vendor documents are agreed before work begins.
The Opportunity Sprint can establish the evidence needed to scope a production pilot; it does not pre-commit either party to a rollout.
- Contracting entity and currency confirmed in writing
- Milestones and acceptance criteria defined in the proposal
- Vendor-document requirements identified before signature
- Scope changes require an explicit written decision
Delivery controls (Germany)
Testing, observability, release, security, and handover controls are selected for the actual system risk rather than promised as a generic bundle.
Acceptance measures and production responsibilities are recorded before implementation so both teams know what evidence will support release.
- Risk-based testing and acceptance measures
- Release, rollback, and observability responsibilities
- Security controls tied to the agreed threat model
- Handover artifacts defined in the signed scope
