Mosaic ERP v1.3.2 turns a plain-English owner interview into the working retail ERP.

Instead of asking an owner to pick technical modules, Mosaic asks how the business actually runs: products, locations, buying, receiving, stock, sales, returns, credit, staff responsibilities, reporting, terminology, currency, and branding. Those answers configure the running system itself.

The working system, not a planning artifact

The interview produces a reviewable configuration summary and opens the configured ERP. The Modern Ledger interface gives operators a direct path through Today, Stock, Sales, Buying, Money, Books, and Administration.

The retailer core covers:

  • purchasing and receiving
  • products, inventory, movements, counts, and locations
  • sales, payments, and returns
  • supplier bills and payments
  • cash and bank workflows
  • immutable double-entry journals
  • trial balance, profit and loss, and balance sheet
  • role- and location-scoped access with audit history
  • PostgreSQL and container deployment, with SQLite for local evaluation

Built for local fit

Mosaic is not tied to one demo country or one retail vocabulary. During configuration, the owner sets the business currency, region, terminology, locations, operating model, and brand. The resulting workspace reflects those choices.

That is configurability, not a claim of automatic legal or tax compliance. Local requirements still need to be reviewed for the business and jurisdiction.

Available now on Windows and Mac

v1.3.2 adds direct desktop installers alongside the open-source, self-hosted deployment path.

Mosaic is MIT licensed. The source has no software licence fee; hosting, migration, operations, implementation, and professional review can still cost money.

For retail operators and ERP implementers: which setup decision creates the most friction when opening a new store or moving from spreadsheets?
