What DonauMorgen is

A suite of business applications for Mexican companies. Each one does its whole job, and they all share sign-in, billing and data through the Core.

The products

• Almacly In production

  Multi-location inventory, lots and warehouses for any line of business, with optional verticals — the agri lot with size, grade and cold chain is one of them, not the only way to use it.

• Comprora Open beta

  No purchase order without who requested it and who approved it. Requisition, named approval and receipt matched against the order.

• Fletara Open beta

  Freight management with tamper-proof evidence for every delivery.

• Contabele In production

  Mexican e-invoicing (CFDI 4.0), payment complements, Carta Porte and receivables in one place, with each company’s PAC credentials encrypted and isolated.

• NomixHR In production

  One record per employee that serves both to stamp payroll and to withstand an IMSS or STPS review. Includes NOM-035.

• Relavian Open beta

  One record per customer — first email, opportunity, signed contract, who changed what — with an AI assistant on top.

• Tianpos Open beta

  A point of sale that does not duplicate your inventory: it writes to the same warehouse as the rest of the operation.

• Acoply In production

  The field logbook a PrimusGFS or GlobalG.A.P. audit will ask for: tasks, sprays with their pre-harvest interval and harvest, captured on the phone by whoever does them.

• Frambia Open beta

  A B2B fresh-fruit marketplace between companies, with a verifiable record for each counterparty.

• ActivaLog In production

  What happened this week across the 10 areas, without asking anyone for a report: a daily log per area and a dated diagnosis with a health score.

• Suptika Open beta

  Help desk: every customer case with its status and owner, plus contacts, client companies, groups and assignment.

And one for families

How it’s built

Every app follows the same rules, so each can be bought on its own and still work with the rest.

One account

Everyone signs in at id.donaumorgen.com, with a single account for every app their company subscribes to.

An event bus between apps

No app reads another app’s database; they talk through events. Each app writes what happened to its outbox, and the Core delivers it, signed, to the apps that subscribe, with retries; anything that can’t be delivered is set aside, not lost. That’s how Almacly’s catalog reaches Tianpos, and how each app learns what its company has subscribed to.

One database per app

Each app has its own PostgreSQL database with row-level security (RLS): a query only sees the data of the requester’s company.

Billing

Companies subscribe and pay in the console, through Stripe. The Core keeps each company’s plan and tells every app what it includes.

CFDI 4.0

Invoices carry each company’s own digital seal (CSD) and are stamped by a SAT-authorized provider. In the provider’s test environment, income and credit invoices, payment complements 2.0, Carta Porte 3.1 and cancellations already go through.

The stack

Supabase: PostgreSQL with RLS, auth, and edge functions on Deno. React and TypeScript for the apps, Astro for the websites, Kotlin for the Android field app, and Vercel for deployment. Stripe handles billing and Resend sends the email.

Testing

Databases are tested in SQL, functions with Deno, and screens with the Node test runner, Vitest and Playwright.

By the numbers

Measured on November 6, 2026. Each one says how it was counted.

• 45

  active repositories

  In DonauMorgen’s GitHub account, excluding the 2 archived ones. Everything else was counted on each repository’s default branch, which is develop in 42 of the 45.

• 1,245

  database migrations

  The .sql files in supabase/migrations, across 18 repositories.

• 157

  edge functions

  Folders in supabase/functions with an index file, excluding shared code (folders starting with “_”), across 15 repositories.

• 1,347

  test files

  Files named as tests (.test., .spec., _test. or test_*.py) plus the Android tests, excluding dependencies and build output, across 24 repositories.

• 13

  apps in production

  The 12 product apps, at app.<product>.com, plus the Core’s sign-in, id.donaumorgen.com. All of them returned 200 that day.

Writing

On the blog (in Spanish), he writes about the labor and tax rules the suite has to follow, always from the official source.
