Distribution businesses run more systems than anyone can reconcile: an ERP for finance, a separate system for warehouse movements, a portal the regional agents use, and ETA e-invoicing because the law requires it. Four systems, four versions of the truth, and a receivables position nobody trusts until an accountant rebuilds it by hand. We build the layer that resolves them into one model — so that a customer is one customer, an invoice is one invoice, and the stockout, the slow-paying account and the SKU heading for expiry are visible while there is still time to act on them.
