Five tools that disagree.
Most growing businesses sell in one tool, buy in another, count stock in a spreadsheet and invoice somewhere else. Each one is fine alone. Together, nothing agrees, and nobody knows what a project cost until it's closed.
The same customer, spelled four ways
Every hand-off is a re-type. Every re-type is a chance to drift.
One record, read by every module
The customer on the invoice is the same record the quotation was raised against.
Every document remembers the one before it.
Follow one job through Circumz. Each step is created from the last, so the customer, scope, quantities and cost carry forward on their own, and margin is visible the whole way through.

No re-keying
Quotations become contracts, contracts become projects, POs are raised from BOQ lines. The data moves; nobody retypes it.
Cost where it happens
Material issued to site posts to the project the same moment the stock leaves the warehouse, not at month-end.
Margin while it matters
Budget, actual and invoiced amounts sit on one project record, so an overrun shows up in week six, not at handover.
Real screens. Real workflows.

Sales
A quotation becomes a sales order, a sales order becomes a customer contract, and a contract becomes a project. Customer, pricing and scope carry forward at each step.

Projects
The project is where the other modules meet: the contract that funds it, the BOQ that defines it, the stock issued and bills received against it, the progress recorded, the invoices raised and the margin it is actually producing.

Procurement
A purchase starts from a need, such as a BOQ line or a stock shortfall, and moves through approval, ordering, receiving and billing without losing the project it was bought for.

Inventory
A shared item catalogue with minimum levels across any number of warehouses. Every receipt, transfer, issue and adjustment is a movement with its reference, and cost is carried at moving average so valuation and margin come straight from the ledger.

Finance
Invoices come from contracts, projects, rent schedules, timesheets and farm sales. Supplier bills come from purchase orders. Payments settle either side, and aging shows what is outstanding. Multi-currency and tax codes are part of the document, not a report afterwards.

Accounting
A double-entry general ledger in the company's base currency. Invoices, payments, bills, stock movements, retail sales, expenses and farm, fleet and lease costs post automatically at the same moment as the document, so the books cannot disagree with the operation. Accounting is switched on per company when you are ready.

Manpower
For companies that supply workers to customers. Rate cards set what each trade bills, deployments put a worker at a customer from a date, timesheets are approved by the customer's signatory, and approved hours become a draft invoice. Margin is billed value against the worker's loaded cost.

Agriculture & Livestock
Farms and fields, crop cycles with inputs and costs, harvests valued at what they cost to grow, and produce sold to customers. Livestock adds herds and flocks with a headcount ledger, feed, health and production records and animal sales. Margin is reported per crop, per cycle and per herd.

Logistics
A shipment is tied to a customer and a sales order, put onto a trip with a vehicle and driver, tracked through pickup and transit, and closed with proof of delivery.
The books, the payroll and the country setup are built in.
You don't bolt on an accounting package or a payroll tool later. They read the same records as everything else.
Books that keep themselves
Invoices, bills, stock and sales post to the ledger as they happen, so the month-end numbers are already there.
See how it worksPayroll from real attendance
Leave, overtime and pay come from the records your managers already keep. Approve once, then pay.
See how it worksSet up for your country
Your currency, your tax rules, English and Arabic. Invoices follow the country you work in.

How Circumz keeps your business data accurate and private.
Role-based access
Owner, finance, procurement, warehouse, logistics, fleet, sales, property, store, cashier, farm, HR and manpower roles, with permissions per module for view, create, edit, delete and approve.
Structured workflows
Records move through defined statuses. A purchase request is approved before it's ordered; a purchase order is received before stock is updated.
Figures that always add up
Stock, cost, invoices and accounting entries are saved together or not at all, and every entry must balance, so your numbers never disagree.
Your data stays yours
Each company's records are kept completely separate, so no one can see another company's data, even by mistake.
Country-aware e-invoicing
Numbered, locked tax invoices anywhere, with the local tax name and ID. Saudi ZATCA structure is built in; demo mode is labelled and never submits.
Modular by design
Modules share the same records, so adding one is a setting, not a separate project or a data move.
Field notes on running the business.
Month-end close when the ledger posts itself
Most of a month-end close is making separate systems agree. If every document posts to the ledger at the same moment, the close becomes a review.
Invoicing in a foreign currency without the spreadsheet
What has to be true of a quotation, an invoice and a payment for exchange differences to appear on their own, and where the limits are.
How a monthly payroll run works, step by step
From attendance to the bank list, and what each stage freezes. A walk through one month in Circumz HR, with the parts we do not automate.
Common questions
What is Circumz?
Circumz is a modular ERP. CRM, sales, procurement, inventory, finance, accounting and HR share one record, with extra modules for contracting, logistics, retail, real estate, agriculture and manpower supply that you switch on one at a time.
What is a modular ERP?
A modular ERP is one system built from parts that share the same customers, stock, money and people. You start with the parts you need and switch on more later, without moving your data. How modular ERP systems work explains it step by step.
Which businesses is Circumz built for?
Circumz has solutions for construction, transport & logistics, real estate, retail, agriculture & livestock, manpower supply, trading & distribution and services businesses. See the solutions to find the modules that fit how you work.
Why isn't there a published price?
Because a contractor, a farm and a shop use different modules, and a flat per-seat price would overcharge one and undercharge another. We would rather scope it with you than publish a number that looks simple.
Is there a free trial?
The fastest way to evaluate Circumz is a walkthrough on your own workflow. Request a demo and we'll show the modules relevant to your business.
Is Circumz ZATCA certified?
Saudi invoices follow ZATCA's document model: invoice types, hash chain, XML and QR. Submission runs in a labelled demo mode and never reaches ZATCA's live platform, so we make no claim of certification. See the ZATCA guide for what to check in any system.
