The 30 Second Summary:
Manual ordering quietly burns 30 to 60 hours a week across 10 sites. That is £900 to £1,800 a week in management time.
Manual data entry errors add up fast. Even a 2% error rate can mean £300 a month gone on fixes.
Invoice admin is a big cash leak. 500 invoices a month can cost around £6,750 in manual processing.
Automating quotes, ordering and invoice matching gives you control. Your project manager and site manager time goes back to running the job not chasing suppliers.
You are not losing margin to materials alone. You are losing it to admin.
Every quote chase, every duplicate order and every invoice mismatch is profit leaking out of your business.
See the real cost of manual ordering
Your site managers lose 3 to 6 hours a week to ordering admin.
Run 10 active sites and that is 30 to 60 hours every week.
At £30 an hour fully loaded that is £900 to £1,800 a week. Up to nearly £94,000 a year.

Stop paying the error tax
Manual data entry sits around a 2% error rate.
If you process 200 orders a month that is 4 errors.
At roughly £75 a fix that is £300 a month gone. For nothing.
Common ones you will recognise:
Wrong product or wrong spec
Duplicate orders because two people ordered the same thing
Wrong site or wrong plot
Wrong quantity so labour waits

Cut invoice admin before it cuts you
Manual invoice processing can cost £12 to £15 per invoice.
If you are doing 500 invoices a month across 10 sites that is about £6,750 a month. £81,000 a year.
