A SaaS platform is software your customers log into and pay for month after month: multi-tenant, account-based, and running on its own. We design and build the whole product: the application, the accounts and permissions behind it, the subscription billing that collects the revenue, and the admin tools you use to run it. It is the difference between selling your service one project at a time and selling a product that keeps earning while you sleep.
What's included
The full product your customers use, front to back, designed and engineered under one roof. Built on a stack you can hire for and own outright, with no lock-in to us.
Sign-up, login, password resets, and team invites, with each customer's data cleanly walled off from the next. Roles and permissions so owners, members, and your own staff each see only what they should.
Stripe-backed plans, trials, upgrades, downgrades, and cancellations, with proration and failed-payment handling built in. Revenue collects itself; you watch it from a dashboard.
A private back office where you manage tenants, adjust plans, issue refunds, and read the numbers that matter. The controls you need to run the business, not just the product.
Transactional and lifecycle messages (welcomes, receipts, trial reminders, dunning), wired into the product so new accounts activate and lapsed ones get a nudge.
The platform live on your own infrastructure and domain, with environment setup, monitoring, and a plain-language runbook. Full repository access so the codebase is yours from day one.
Our process
We map who pays, for what, and on which plan: the tenants, the roles, and the core jobs the product has to do. The pricing model is decided here, because it shapes everything built after it.
We design the data model, the tenancy boundaries, and the billing logic before a screen is built. Getting this layer right is what lets the platform grow without being rewritten.
We design the screens your customers live in and the admin console you run them from. Calm, fast, and clear: interfaces people understand on first use.
We engineer the application, the accounts, and the subscription billing as one connected system. You see working software in short cycles, not a black box.
We run real accounts through the full lifecycle (sign-up, payment, upgrade, cancellation, failed card) until every path holds. Edge cases get found here, not by your first customer.
We deploy to your infrastructure and domain, hand over the repository and runbook, and stay on to keep it running. The product goes live as yours to own and scale.
