Per-company data separation
Each customer's data is separated from the others at database level; one company's record cannot accidentally appear to another. The separation is checked on every query, not only in the interface.
DOKI / Software
Software · SaaS and subscriptions
If you want to offer your software to many customers by subscription, the architecture must be built for it from day one. We design together the structure that separates customer data, plan and entitlement management, subscription flows and usage reports.
- Company isolation
- Plans and entitlements
- Subscription flows
- Usage reports
01 / What this service includes
An architecture that grows from one customer to a thousand.
Plans and entitlements
Which plan includes which feature, how many users and how much usage is managed from one place. Adding a plan or moving a feature to a higher plan needs no code change.
Subscription flows and usage reports
Trial, upgrade, renewal, suspension and cancellation are modelled as clear states. A late payment notification cannot accidentally reopen a closed subscription.
02 / How it works
The layers of a SaaS product
Beneath the screen the user sees, four layers make the product scalable.

03 / Scope
Let's define the scope together.
We clarify the scope, deliverables and acceptance criteria together in the first meeting. The written quote lists that scope item by item; if the scope changes, the quote is updated as a new version.
We agree goals, deliverables and timing. Scope is defined for each engagement.

06 / FAQ
The questions on your mind.
Tell us what you need; we will define the scope together.
Tell us about your projectDoes the system collect payments itself?
Collection goes through the payment provider you choose; card details are not kept in your system. We build the subscription states, the notifications coming from the provider and their effect on entitlements; choosing the provider and the commercial agreement are yours.
How long does a project take?
It depends on scope. After the scope meeting we share the stages and an estimated schedule in writing; you follow progress in My account.
How is the price set?
There is no fixed package price. Once the scope is clear we prepare an itemised quote; nothing you have not approved is included.
