Turnkey design and development of B2B/B2C SaaS platforms

We transform your digital idea into a scalable cloud business model with a steady regular income (MRR/ARR). We develop a multi-tenant architecture (Multi-Tenant), recurring billing via Stripe / Paddle, tariff plan and limit management, user onboarding, and extended churn rate analytics.

✓ Automatic billing: recurring subscriptions, trial periods, tariff upgrades/downgrades via Stripe Billing
✓ Data isolation (Multi-Tenancy): separate database schemes or logical isolation of tenants
✓ Role-Based Access Control (RBAC): flexible rights for company owners, administrators and managers
✓ Scalability readiness: seamless support for thousands of paying subscribers without base degradation

Regular income model

Why the SaaS model generates several times higher business capitalization

Projected regular client payments create a stable financial flow and maximum company value multiplier

[ 01 ]

Predicted monthly recurring revenue (MRR)

Clients pay monthly or annually for a subscription. You are free from seasonal fluctuations and can confidently plan development.

[ 02 ]

High LTV (customer life cycle)

A high-quality cloud tool has become an inseparable part of daily work for client companies, maintaining them for years.

[ 03 ]

Global market without geographic borders

Support for multilingual, automatic VAT (VAT/Sales Tax) calculation and international cards allows selling services around the world.

[ 04 ]

Automatic data collection without managers

The system automatically withdraws funds, issues invoices, sends reminders about the expiration of the card term and blocks non-payers.

[ FREQUENT QUESTIONS ]

Answers to common questions from customers

Key details regarding terms, independent website editing, and rights transfer.

Stripe is a classic payment gateway with the lowest fees (2.9% + 30¢), but you will have to manage taxes (VAT/Sales Tax) yourself in every country. Paddle operates under the Merchant of Record (MoR) model — they pay all taxes themselves in 200+ countries around the world, removing legal and accounting risks from you in exchange for a slightly higher fee (5% + 50¢). We help choose the best solution for your jurisdiction.

We use multiple layers of data-isolation checks: at the database level, every query is automatically filtered by Tenant ID (or directed to a separate schema), while the API enforces automatic authorisation through session tokens. No user can view or change another user’s data.

The automatic Smart Retries (Dunning Management) algorithm is activated. The system retries the charge after 1, 3 and 7 days, while sending polite emails with a link to update payment details. If payment fails, the subscription is automatically set to “paused” without deleting the customer’s data.

Yes. The architecture of the billing project is flexible: you will be able through a convenient Stripe control panel to create new tariffs, configure annual payment discounts, generate Black Friday promo codes and change limits without the need to rewrite the source code.

Yes. We connect specialized SaaS analytics, which in real-time build charts of MRR growth, net revenue retention coefficient, customer acquisition cost (CAC) and customer payback period.
