Pullstok: the ERP I design, build and run
A multi-tenant SaaS ERP that runs the whole operation of a company, with one or many branches and retail or wholesale sales: point of sale, stock, electronic invoicing, an online store, payments and an accounting module in development. It is in production and I own it end to end: product, architecture, code, infrastructure and deploy.

What's inside
Multi-tenant
Isolation at the ORM level
Every request runs inside its business context with AsyncLocalStorage, and a Prisma extension scopes every query to that business. If the context is missing, the query fails: a business never sees another one's data.
Tax integration
ARCA from scratch, over SOAP
Electronic invoicing with no third-party SDK: CMS/PKCS#7 signing, WSAA and WSFEv1, per-business certificates with keys encrypted with AES-256-GCM, and sales turned into invoices with fiscally correct amounts.
Hardware
A cloud to local hardware bridge
A Windows agent shipped as a single Node executable that prints ESC/POS to thermal printers, with code pairing to print from a phone. Plus scale label decoding and camera barcode scanning.
