Estimates that become the job

Win the work with a clear, itemised estimate, then turn the approved version straight into a project without re-typing a single line. Bill in stages as work completes, by milestone or percentage, and handle retention so the final account adds up. Your client gets a professional certificate; you keep one clean trail from tender to final payment.

Know the job is making money

Cost and margin, job by job

A busy site can hide a loss-making job. Paper & Pen attributes every purchase order, supplier bill and payroll run to the project, then shows actual cost against your estimate as the work progresses. You see the margin before the job is over, not after. Built in Oman with native OMR, AED and SAR and 5% VAT, and ready for USD, EUR or any market and tax rate.

Questions

Everything you need to know

Can I invoice a project in stages?

Yes. Bill by milestone or by percentage complete, with retention handled, so each certificate is clean and the final account reconciles.

Can I track cost against my estimate?

Yes. Purchase orders, supplier bills and payroll attribute to the job, and Paper & Pen shows actual cost against your estimate as work progresses.

Does it handle retention?

Yes. Retention is tracked through progress invoices and carried to the final account, so nothing is missed at handover.

Can I run payroll for site staff?

Yes. The HR and Payroll module runs wages and can attribute labour cost to the right project for accurate job costing.

Is quoting free for contractors?

Sales and Invoicing, including estimates and progress invoices, is free forever. Add Inventory, HR/Payroll and Accounting for full project cost control.
