ScreensConcept
Desktop app: SaaS teams configure multi-tenant organizations, write role policies, review billing and audit logs in sustained backend work with dense data and many configuration fields. Sample screens on a computer, in the proposed brand. Their numbers are sample data.

About this appAI proposal
Keyledger gives SaaS teams one service for the three things every multi-tenant app needs: who a user is, what they may do, and what they owe. Sign-in, organisations, roles and metered billing share one data model, so there is no sync job between an auth vendor and a billing tool.
It is built for product engineers who would rather run this layer themselves than rent it. Deploy it to your own cloud, or use the managed version and move later. Policies and billing rules are plain files you keep in your repository, not settings locked in a vendor dashboard.
The material shows teams today stitch together an identity provider, hand-built role checks and a separate billing platform. Keyledger replaces the glue code with one API and one audit trail.
- Tagline
- Who they are, what they can do, what they owe. One service you control.

- PlainPrecisePractical
- Why this name
- A key opens doors and a ledger records what is owed. The name joins access and billing, the two jobs the product does together.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Organisations and members
Tenants, invitations and per-tenant membership are built in, so each customer account maps to a clear organisation from the first sign-in.

Roles and policies as code
Define fine-grained permissions in versioned policy files. Review changes in pull requests and test them before they reach production.
No member yet
Usage metering and invoices
Send usage events from your app, group them by tenant and plan, and produce invoice lines that follow the same tenant model as access.
No member yet
One check for access and plan
Ask once whether a user may do something. The answer takes their role and their plan limits into account together.

Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Partners and integrations. Developers find it through open-source repositories, framework starter templates and guides for connecting it to common web frameworks and payment processors. Each adopting app depends on it.
- Do they become customers?
- Readers are engineers who can become paying managed or enterprise customers. Test whether self-hosters convert to the managed tier, and whether template listings bring qualified teams.
- First customers
- Engineering leads at B2B SaaS startups with 5 to 30 engineers who are adding per-tenant roles and usage billing and do not want to pay per active user.
- Where to reach them
- Developer communities: Publish a migration guide from hosted auth to self-hosted, and post in Hacker News, Reddit and Discord for SaaS builders.
- Open-source repository: Ship starter templates and examples for popular frameworks, and answer issues quickly to build trust.
- Direct outreach: Contact teams who publicly discuss auth or billing pain and offer to help them migrate.
- First milestone
- Five teams run it in production, and three of them pay for managed hosting or support within 90 days.
Why people already pay for this
- VerifiedGitHub repository gained 344 stars in 2052 days
- Public claimFrontier is an open-source alternative to proprietary user management platforms like Clerk and WorkOS, implying those platforms charge for their services and serve SaaS teams.
- Public claimFrontier integrates identity, access control, and billing—three functions SaaS teams need together—suggesting demand for unified user management solutions.
- VerifiedWorkOS's pricing page lists 7 paid plans, from $99 to $2,500 a month, plus a free plan and prices on request for larger customers

RisksAI inference
- CommercialOpen-source projects often struggle to turn users into payers. Most teams may self-host free and never buy managed hosting or enterprise features.
- TechnicalAuthentication is security-critical. Flaws in sessions, SSO or token handling would damage trust quickly, and an independent security review is needed.
- CommercialAn open-source alternative to Clerk and WorkOS already exists per the material. Keyledger must show a clear difference, such as tighter billing and policy-as-code.
- RegulatoryStoring user identities and billing data brings privacy duties, and managed hosting makes us responsible for them. Payment tax handling may also be needed.
- PlatformBilling depends on payment processors. Supporting several, or switching between them, adds integration work and may limit usage-based features.
