SaaS Development
If your internal tool solves a real problem, other businesses will pay for it. We turn internal machinery into multi-tenant products: accounts, billing, onboarding and the operational discipline SaaS demands.
Sound familiar?
An internal tool others would pay for
Real value locked single-tenant, with no accounts, billing or onboarding to sell it.
SaaS plumbing underestimated
Subscriptions, dunning, isolation and support tooling: the 60% of a product that is not the feature.
This service exists because we kept meeting these two. Here is what fixing them properly includes.
What's included.
DAT / saas-development
Multi-tenant architecture
One codebase, many customers, each one's data properly isolated.
Subscriptions and billing
Plans, trials, invoices and dunning wired to your payment provider.
Self-serve onboarding
Signup to first value without a sales call in the loop.
Operational readiness
Monitoring, support tooling and upgrade paths before the first paying stranger.
The toolkit for this work
How business systems work runs here
Map where truth lives
Which system owns the customer, the stock, the money, and where the copies disagree today.
Design the single record
One event updates everything it touches; nothing is typed twice.
Migrate in stages
Existing data moved and cleaned while work continues. Never a switchover cliff.
Keep the numbers closing
Reports that reconcile to events, so the figure your accountant sees is the figure that happened.
What it's judged by.
Every engagement reports these: the numbers, not the vibes.
Numbers that agree
Stock, orders and cash matching across every screen that shows them.
Time to answer
How fast "what is the status of X" gets answered without asking a colleague.
Adoption
A system nobody uses is shelfware; we measure whether the team actually lives in it.
This is for you if
- Companies whose customer history lives in five inboxes
- Operations where stock, orders and money never quite reconcile
- Founders who cannot answer "how are we doing" without a day of spreadsheet work
And honestly not, if
- Buying software to avoid fixing a process: the process comes first
- Teams unwilling to retire the old spreadsheet once the system runs
We turn down work that fits this column. It is cheaper for both of us early.
“A business system has one job: make the numbers agree with reality.”

Asked about this service.
Can you take equity instead of fees?
Our default is fees with your full ownership. Where a partnership genuinely fits both sides we discuss it openly. Never as a discount trick.
