We take care of the boring stuff of running a SaaS business:
User logs in via OAuth. We verify the user and send your app a JWT token with your app permissions.
User forgets her password. We let her reset it.
User signs up. We verify the email address.
Our email template engine renders your branded emails.
We send from your email provider for a consistent, professional experience.
We run the web shop for you.
You define your plans, prices and features.
User buys a plan and pays via your payment provider. We handle the web hook.
We update the auth database, re-sync all entries on errors.
We run the recurring charges.
We compute taxes and send the user a legally compliant invoice PDF.
We generate custom invoice designs, using your brand colors, logo, and fonts.
User needs all invoices from the year 2026? Available in user portal.
User changes the email address. We re-verify it, and sync it to authentication and billing.
User configures notification preferences, exercises GDPR-data export, and more. Not your problem.
User wants to see her account and plan status. We show her current subscription, next billing date, and all invoices.
You need to manually enable a user? Use the admin portal we run for you.
Export or import customer data.
Of course, with an agent you can 'quickly' generate it. But then: Testing it? Making it robust? Running it 24/7? You could do all this boring stuff, but you could also work on your app instead.
Time to market. Iterate faster. Validate faster. Most customizations are optional.
Focus on your app functionality.
