Part five
Identity, tenancy, communication, documents and AI — the parts every other module depends on.
Accounts, roles and granular permissions, two-factor authentication, password reset and self-service account management.
Company registration with a 30-day trial, per-tenant module subscriptions, invitations, tenant switching and host-level impersonation.
SMTP email with a delivery log, real-time in-app chat over SignalR, record comments, and HMAC-signed outbound webhooks.
Reusable email templates, a delivery queue and a searchable log of everything sent, so support can prove what a customer received.
Google Drive as the system of record for business files — browse, upload and attach without leaving the application.
Market-trend analysis, patent checking and review, supplier discovery, staff-performance evaluation and user-behaviour analytics.
An AI help centre that ingests your own documentation, chunks it by heading structure and answers questions against on-device vector embeddings.
Text extraction from PDFs plus OCR for scanned documents, turning paper and PDF into searchable, structured data.
System configuration, admin-gated menu curation, six UI themes, import templates and searchable exception logs.
Per-user recently visited pages, synchronised from the browser, with de-duplication and a session clear.
Scheduled SQL Server backups uploaded to Google Drive, with a guided restore that handles single-user mode and recovery for you.
Architectural Deep Dive
This is the flow a buyer walks, and each step is handled by code that enforces the same rules as the ERP — because it is the same code.
Most platforms split storefronts and ERP into separate, decoupled applications connected by fragile cron jobs, webhooks, and eventual consistency. When traffic spikes, stock counts drift, overselling happens, and back-office operators spend hours reconciling orders. In ModApp, the web storefront is a direct projection of the core domain: the exact same MediatR commands, SQL Server transactions, and business rules govern both the buyer checkout and the warehouse shipping floor.
The buyer visits /{tenantCode}/store. ModApp extracts the tenant boundary from the route prefix, loading the catalog via GetStorefrontCatalogQuery.
Dynamic theme injection (ITenantThemeService) applies tenant branding, logos, and accent colors with physical database query filtering.
No registration wall required. Anonymous shoppers receive a signed ec_session cookie. Items added trigger AddToCartCommand to persist the basket.
IShoppingCartIdentity guarantees carts are strictly owner-scoped by Session ID or Customer ID. No shopper can read or manipulate another's cart.
When a guest logs in or signs up during checkout, ModApp triggers MergeStorefrontCartCommand to transfer transient guest lines into their permanent customer cart.
Merges duplicate SKU quantities, applies existing member discount tiers, and safely retires the transient guest session cookie without losing basket history.
The checkout form never trusts client prices. Subtotals, active coupon codes, and shipping rates re-calculate server-side using GetTaxRatesQuery and active carrier tables.
Tax engine matches country/state tax codes; coupons enforce expiration and usage counts; zero client-side price payload vulnerability.
Before payment processing, GetStockSummariesAsync evaluates real stock across warehouse bins. ReserveStockBatchAsync reserves SKUs atomically.
Batch SKU ledger locking prevents overselling during checkout spikes. If any item is unavailable, checkout halts cleanly and the cart remains intact.
Payment intent is authorized before creating the sales order. ModApp supports Stripe, PayPal, Adyen, and simulated gateways with automated failover via IPaymentGatewayResolver.
Zero card data stored (PCI compliant). Payment decline triggers atomic rollback: no orphan sales order is generated, and the shopper's cart is preserved.
Checkout dispatches CreateSalesOrderContractCommand directly into Modules.Sales, auto-resolving customer identity in Modules.Partners.
B2B on-account purchases run fail-closed credit checks via ICreditCheckService. Order enters the exact same table as manual back-office orders.
The sales order emits domain events via the transactional outbox to trigger warehouse picking, logistics carrier allocation, and General Ledger journal entries.
Generates real-time tracking at /{tenantCode}/orders/{tracking}. Live milestone updates synchronize directly with warehouse pick/pack events.
Modules.Partners with unified address books and credit history.
Every tenant provisioned on ModApp receives its own isolated, fully branded web storefront.
Test the storefront routing with pre-seeded demo tenants like ebuyerhub, sajjad, or your own registered tenant code:
/{tenantCode}/store
/{tenantCode}/products/{id}
/{tenantCode}/cart
/{tenantCode}/checkout
/{tenantCode}/orders/{tracking}
/{tenantCode}/dashboard
Questions
ModApp supports both managed cloud hosting and dedicated infrastructure. ModApp targets SQL Server and is deployed as a high-performance .NET 10 modular application with full multi-tenancy, isolated module schemas, and complete data governance.
The 13 core modules are always available, because core modules are enabled by platform definition rather than by subscription. The other 17 are per-tenant modules you switch on from the in-app module store.
One platform. Each module owns its tables in its own SQL schema behind its own EF Core context, but modules integrate through published domain events and a transactional outbox — so approving a document in one module can post an entry in another.
The help centre's retrieval path is on-device: documents are chunked and embedded with a local ONNX model, so answers are retrieved directly from your own corpus inside your deployment with vector similarity search.
We'd rather list the gaps than have you find them in month three. SSO/SAML, SMS notifications, point-in-time database restore and branch-level data isolation are not implemented. Inventory reorder rules report items below threshold; they do not yet raise purchase requisitions or send alerts automatically.
Register a company and you have 30 days with all 13 core modules. Turn on the rest whenever you are ready.
