The reality on site

Construction operations become chaos without control.

Most construction, civil, and engineering firms run their entire operation on a patchwork of spreadsheets, emails, and paper trails. InventFlow replaces that patchwork.

Without InventFlow

Spreadsheets & paper trails

  • Lost stock & untraceable movements
  • Spreadsheet-driven procurement
  • Unapproved purchasing slipping through
  • Zero project material visibility
  • Warehouse discrepancies discovered too late
  • Manual approval emails & WhatsApps
  • Fleet fuel abuse going unnoticed
  • Disconnected site & office teams
With InventFlow

One operational platform

  • Every inventory movement logged & auditable
  • Requisitions → approvals → POs in one platform
  • Hard-gated approval chains enforced everywhere
  • Material ledger per project, in real time
  • Stock-on-hand reconciled across warehouses
  • Notifications, escalations & SLA timers built-in

Enterprise SaaS architecture

Engineered for multi-site, multi-tenant operations.

InventFlow is built on the same architectural patterns used by leading B2B SaaS platforms.

Multi-Tenant Architecture

Each company runs in an isolated tenant. Zero data bleed between firms.

Row-Level Security

PostgreSQL RLS enforces data isolation at the database, not just the app layer.

Role-Based Permissions

Operations Manager, Procurement, Warehouse, Site PM — each role sees only what they should.

Cloud Infrastructure

Hosted on enterprise-grade cloud with daily backups and audit-grade durability.

Notification Engine

Approval pending? Low stock? Overdue PO? Real-time in-app + email alerts.

Email Workflow Engine

Templated approvals, escalations, and supplier dispatch flows out of the box.

Stack:SupabasePostgreSQLReactTypeScriptTailwindEdge Functions
Industries

Built for South African operators.

From single-site contractors to multi-region operations — InventFlow scales with you.

Construction

Main contractors, sub-contractors, and developers managing site materials and project budgets.

Civil Engineering

Roads, bulk earthworks, water & sewer — multi-site material and plant tracking.

Electrical Contractors

Cable, switchgear, and electrical fittings reconciled per project and per stage.

Facilities Management

Spare parts, consumables, and maintenance materials across portfolio sites.

Engineering Operations

Workshops, plant hire, and asset-heavy ops with strict cost control.

Multi-Site Warehousing

Security & auditability

Built for accountability.

When the auditor asks who approved that purchase order, you have the answer in two clicks.

Every change tracked

Who, what, when, before, after. Every stock movement, every approval, every override.

Immutable audit trails

Audit records are append-only. Nothing can be silently edited or deleted.

Role-based permissions

Granular access by role and by warehouse. No screen, button, or report is one-size-fits-all.

Approval enforcement

POs cannot be issued without the required approval chain — enforced at the database, not just the UI.

Secure access control

SSO-ready, session-managed, with optional 2FA for sensitive roles.

What operators say

Run by people who live on site.

We cut unapproved purchases by 92% in the first quarter. Every requisition now has a paper trail before a single rand is spent.

Operations Manager
JHB-based civil contractor · R 480m turnover

Before InventFlow, project material costs were a guess until month-end. Now I see budget vs actual live, per project, per cost code.

Construction Director
Multi-site building contractor

Warehouse reconciliations used to take three days. With per-bin movement history we close them in an afternoon.

FAQ

Questions about InventFlow.

Is InventFlow a true multi-tenant SaaS platform?+

Yes. Each company runs in an isolated tenant enforced by PostgreSQL Row-Level Security. No data ever bleeds between companies, and role-based permissions are checked at the database, not just the UI.

How are approval workflows enforced?+

Requisitions follow a configurable multi-step approval chain (e.g. Site PM → Procurement → Ops Manager) with value thresholds. Purchase orders cannot be issued without the required approvals — this is enforced server-side, not just in the front-end.

Can InventFlow track materials per project?+

Yes. Every issued, transferred, or delivered item carries a project tag. The project ledger shows budget vs actual material spend, committed POs, and remaining budget in real time.

Does it work for multiple warehouses and yards?+

InventFlow is built warehouse-first. Stock-on-hand, transfers, reorder points, and audit history are all per-warehouse. Site yards are first-class warehouses too.

What about fleet, fuel, and deliveries?+

Fleet management ships with the platform: vehicle register, driver assignments, fuel logs with abuse alerts, service intervals, and signed proof-of-delivery for site dispatches.

How does pricing work?+

Tiered enterprise pricing based on warehouses, users, and modules. Starter (single site), Professional (multi-site), and Enterprise (group-scale). All plans include audit trails, RLS, and approval workflows.

Stop managing operations with spreadsheets.

Bring inventory, procurement, warehouses, fleet, and project costing into one connected platform.
