Selected work

Explore our experience

Comparing legal models for a digital platform

Organising processes, reviewing the agreement and planning successive payment-model iterations for a digital platform.

Business outcome: The platform launched quickly, with further payment-model iterations able to be introduced progressively as the business develops.

SaaS documentation aligned with the product

Terms, a DPA, privacy information and data-migration arrangements prepared ahead of a SaaS product’s planned launch.

Business outcome: The product’s legal framework is prepared for its planned launch and further development. Addressing data migration and changes in Data Act requirements reduces the risk of costly changes to the service model after launch.

Legal support across your SaaS business

Contracts, subscriptions, data arrangements and product rights need to reflect the same service.

01

Contracts and customer terms

  • SaaS, platform and online-service terms
  • B2B SaaS agreements, order forms and enterprise terms
  • Consumer models and digital-service requirements
  • Accounts, user roles, acceptance and permitted use
  • APIs, integrations and external-service dependencies
02

Subscriptions and liability

  • Billing periods, renewals and payments
  • Changes to plans, pricing and features
  • Termination, account suspension, data export and deletion
  • SLAs, availability, support and maintenance
  • Complaints, liability caps and service credits
03

Data, IP and enterprise requirements

  • DPAs, GDPR, subprocessors, vendors, transfers and retention
  • Security requirements and questionnaires
  • Software rights, licensing and third-party components
  • AI features, input data and responsibility for outputs
  • Preparation for enterprise procurement and due diligence

When the product needs new arrangements

A new plan, customer segment or integration can require changes to both the product and its terms.

  1. 01

    Before launching paid sales

    Agree the contracting model, customer terms, subscription rules, DPA and immediate risks before each customer receives a different set of promises.

  2. 02

    When changing the business model or pricing

    New packages, usage-based billing, trials and price increases need a consistent approach across product, communication and documents.

  3. 03

    Before entering the consumer market

    Selling to consumers, and certain sole traders with consumer-like rights under Polish law, brings additional information, complaint and digital-service obligations.

  4. 04

    When an enterprise customer arrives

    Procurement commonly reviews liability, SLAs, data, security, audits, exit arrangements and the right to use the product.

  5. 05

    When adding AI or an integration

    Establish what data reaches external services, who is responsible for outputs and what needs to change in the terms and documentation.

  6. 06

    Before investment or due diligence

    An investor may ask for evidence of software rights, team agreements, customer terms, DPAs and consistency between the documents and operations.

The product changes while the terms, subscriptions and liability lag behind

01

Your terms describe a simpler product

An API, AI feature, integration, new plan or user group has arrived, but the documents still assume a single model and a narrow service.

02

Billing and price changes lack clear rules

It is unclear when plans or prices can change, how customers are notified, what happens to the billing period and when they can terminate.

03

The DPA does not reflect the data flow

Subprocessors, transfers, logs, support and integrations are covered only partly, while an enterprise customer expects a clear allocation of responsibilities.

04

The SLA promises more than the product can deliver

Availability, response times and remedies leave out maintenance, external infrastructure, scheduled downtime and the way uptime is measured.

Products we support

B2B SaaS

You sell access to an application and need clear terms for accounts, billing, SLAs, liability, data and termination.

Platforms and marketplaces

You connect user groups, content, payments or integrations and need to define roles, use rules, moderation and complaints.

Consumer subscription products

Your model involves consumers, trials, automatic renewal, price changes and withdrawal rights.

Startups preparing for enterprise sales

The product works, but the customer asks about a DPA, security, subprocessors, SLAs, software rights and an exit process.

What the legal work helps you achieve

We scope the work around your next goal: launching sales, changing billing or signing a larger contract.

Start selling without overbuilding the legal work

We first address what is needed for a paid service to launch. Later features are handled in stages so legal spending does not displace the product budget.

Reduce disputes over payment

Define when billing starts, how plans renew or change and when access ends, reducing grounds for disputed charges and repeated manual support work.

Move enterprise deals through procurement

Prepare the terms and answers needed for supplier review so missing DPAs, IP arrangements or SLA rules do not hold up the sale.

Keep iterating without rewriting everything

Connect changes to plans, payments and features with updates to the terms. The aim is to develop sales without rebuilding the whole document package at each product change.

Before we start

What scope do we start with?

Your next sales step and the features you are actually launching. We review the purchase flow, payment model, data and first customers’ requirements, then scope the documents and operational changes. Later stages can follow product development.

What affects the fee?

The B2B or consumer model, purchase flows, plans, data, integrations and existing documents. The scope also depends on whether we draft your terms, negotiate an enterprise customer’s template or review the product implementation. We agree scope and billing before starting.

What should I send first?

A product link or demo, a short description of customers and pricing, your next goal and any existing contracts or terms. For data or enterprise matters, a vendor list, DPA and customer questions or draft are useful. You do not need a complete package to get in touch.
