For Saudi contracting companies
Enter a number once. BillBrick carries it from the certificate to the ZATCA invoice, the client’s cash and your subcontractors’ payments.
Worked example · fictional figures · SAR
You entered one number. Every other figure was derived from it.
Where the money gets stuck
Certified, invoiced and cash received never agree.
The real balance is unknown until the DLP ends.
Paid before the client pays — or chasing payments already due.
A manual, error-prone step at the end.
BillBrick keeps it in one chain: each number entered once.
Dashboard
Calculated from your records on every visit. Nothing typed in twice.
Invoiced and cleared by ZATCA, VAT declared, and released to subcontractors.
Measured against the budget your commercial manager sets — every revision recorded with its reason.
Cost by category, certified against cost, and your whole portfolio mix.
Certification, contracts, procurement and finance in one system.
Payment certificates (IPC)
Measured work, variations, materials on site and dayworks — cumulative, so “this period” calculates itself.
A client certificate turns Invoiced when its tax invoice is cleared — and Paid when the client pays in full.
Part-certify any line, with the reason on record. Next month copies the lines in one click.
Photos, daywork sheets and the consultant’s certificate — attached where they belong.
Every status change with who and when. After submission, every line change is logged — before and after.
E-invoicing
UBL 2.1 XML, XAdES signature, QR code and hash chain.
B2B invoices go for clearance, B2C invoices are reported — each marked Cleared or Reported.
VAT 15% on the gross; retention never reduces the taxable amount.
Pay-When-Paid
Created automatically: certified, released, outstanding and funded %.
BillBrick proposes it, your commercial manager confirms it. Nothing is released before that.
The client pays 60% of the invoice: every subcontractor’s 60% becomes payable. Never released automatically on certification.
Six kinds of contra-charge, and a payment priority on every liability (1 = pay first).
On site
Nothing to install. Building your own site app? The offline-ready API syncs measurements, photos and goods receipts when the connection returns.
Tested at 375 to 390 pixels wide.
Certified, cost, retention and invoiced — card by card.
Retention your client holds
| Entry | Retention | Balance |
|---|---|---|
| Certificate 4 | +120,000 | 360,000 |
| Certificate 5 | +120,000 | 480,000 |
| Certificate 6 | +20,000 · cap | 500,000 |
Example: SAR 10,000,000 contract · 10% per certificate · cap 5% of contract value · 50% released at Practical Completion

Procurement
Whoever raises an order can’t issue it. An invoice that doesn’t match its order and receipt waits for the commercial manager.
Variations
Approved only with the client’s approval document, reference and date.
Security
Everyone sees only what their role allows — on screen and on the server. Every approval carries a name and a time.
Cost, budget and CVR
Budgets per category, every revision with a reason. Accruals, committed cost and CVR snapshots each period.
Banking
Bank receipts and payments carry the bank’s reference — and link to the client payment they prove.
Client paymentCertificate
Contracts
Clients, consultants and suppliers with VAT number and national address.

Notifications
17 workflow emails, sent from your company’s own mail server.

BillBrick is construction ERP for Saudi contracting companies. It runs the commercial side of a project: from the measured work on site, through the consultant’s payment certificate and the ZATCA tax invoice, to the client’s cash and the subcontractors’ payments.
Main contractors and specialist contractors in Saudi Arabia. Quantity Surveyors, Commercial Managers, Project Managers, Finance, Procurement, Site Engineers and the System Administrator use it every day.
Contract value, value certified, cost, retention held, invoiced and cleared, VAT declared, cash received, released to subcontractors, open liability, commitments and pending variations. Value certified is shown against contract value plus approved variations; cost against the cost budget, never against contract value.
Line by line: measured work, variations, materials on site, dayworks, price adjustment and deductions. Amounts are cumulative, so “this period” is always derived. Lines can be partly certified with a recorded reason, and next month’s certificate copies them in one click. Photos, daywork sheets and the consultant’s certificate are attached; every status change is recorded, and every line change after submission is logged. Client certificates carry the consultant’s reference and evidence. A client certificate turns Invoiced when its tax invoice is cleared, and Paid when the client has paid it in full.
BillBrick is built for ZATCA Phase 2 (Fatoora) e-invoicing: UBL 2.1 XML, XAdES signature, QR code, invoice hash chain and counter. Standard (B2B) invoices are submitted for clearance and simplified (B2C) invoices are reported. Credit and debit notes carry their reason, and the PDF tax invoice is bilingual Arabic/English with the QR code and your logo.
VAT 15% is charged on the gross certified value. Retention is shown as a deduction from the amount payable, never from the taxable amount.
BillBrick tracks the retention your client holds from you. It is deducted on each certificate at the contract’s rate (for example 10%) up to a cap (for example 5% of the contract value plus approved variations). Half is released at Practical Completion and the rest at the end of the Defects Liability Period, each recorded with its certificate. One ledger per contract keeps the balance accurate.
A subcontractor liability is created when their certificate is certified. BillBrick proposes the client certificate that funds it and a commercial manager confirms it. When the client pays, every confirmed liability is released automatically: if the client has paid 60% of the invoice (VAT included), each subcontractor gets 60% of its certified amount. Nothing is released automatically on certification. Contra-charges are supported, and each payment can be marked with a priority (1 = pay first).
Material requisition → purchase order → goods receipt → supplier invoice. Every supplier invoice is matched to its order and goods receipt; a price or quantity outside tolerance puts it on hold until the commercial manager releases it. Whoever raises a purchase order cannot issue it or register its invoice. A purchase-order line can be split across contracts by percentage, and committed cost is visible against the budget.
Ten roles: QS, Commercial Manager, Project Manager, Finance AR clerk, AP clerk, Finance Manager, Procurement Officer, Site Engineer, Subcontractor PM and System Administrator. Each person sees only what their role allows, and every approval is recorded against a named person and time. Optional single sign-on with your OpenID Connect provider, sign-in rate limiting, new users set their own password, and ZATCA keys are encrypted (AES-256-GCM).
The screens are in English. Tax invoices are bilingual, Arabic and English.
Yes, in the phone browser — nothing to install. BillBrick has no mobile app of its own; for teams that build one, an offline-ready API syncs site measurements, photos and goods receipts when the connection returns.
On-premises, in your private cloud, or hosted by us. Each installation serves one company. It runs as one Docker image with a PostgreSQL database, on a Linux server, or on Windows 10/11 for smaller set-ups.
