POS vs ERP vs Accounting API: Use Cases from NoblePOS, Zallo, and Finance Backends

Founders say “we need an ERP.” Operators say “the till is slow and stock is a lie.” Those are different products.

Shipped-related work:

• NoblePOS — retail POS: Vue + ASP.NET Core + SQL Server, inventory and sales
• Zallo — multi-product enterprise suite (Tekvers flagship)
• ERP SaaS platform — multi-tenant ERP
• Accounting System — ASP.NET Core 8 double-entry API (REST + GraphQL), not a full ERP UI
• Industry ERPs (cosmetics, pharma, textile, fertilizer) — plant and compliance modules

Services: custom software, full stack. Company page: ERP & digital transformation.

Use case: POS first

You have a counter, SKUs, and cashiers. You need tickets, payments, and stock decrements now. NoblePOS-shaped work. Do not start with MRP and lot genealogy.

---

Use case: API-first ledger

Finance outgrew spreadsheets. Chart of accounts, balanced journals, fiscal years, roles (Accountant vs Auditor). UI can wait. The accounting-system engagement is this: trustworthy posting, SQL Server, JWT, trial balance procedures.

---

Use case: Industry ERP

Formulas, batches, QC, serialization, FBR e-invoicing, SFA for FMCG. This is a program, not a weekend build. Tekvers case studies for cosmetics/pharma/textile exist because the domain is the product.

---

Use case: Multi-product suite (Zallo-shaped)

Several modules sharing identity and tenancy. Only after two modules have real users. Suites that start as “platform” with no operator workflow become graveyards.
