Numerix Accounting provides accounting and bookkeeping for construction and trades businesses across Sydney and greater NSW — from the CBD and Parramatta to Strathfield, Bankstown, Liverpool, Casula and Fairfield. We know the numbers behind the build: job costing, WIP, retention, progress claims and the compliance that comes with a mixed workforce.
Profit in construction lives and dies on job costing. We allocate labour, materials and subcontractor costs per project, trade and phase in real time, so you see your true margin before the final invoice — not months after the job is done.
If you pay contractors for building services, you must lodge a Taxable Payments Annual Report (TPAR) each August. We track every subcontractor payment, prepare and lodge your TPAR, and run site payroll with allowances, overtime, PAYG and Single Touch Payroll.
Your construction books connect to the rest of your finances — accounting, tax, cash flow forecasting and equipment finance — all under one roof, so nothing falls through the cracks.
