Where the money goes missing
Jobs priced from memory
A missed item or an old price comes straight out of your pocket.

Questions
Who is the kit for?
Small contractors, subcontractors and foremen going independent in Jamaica who price jobs without a quantity surveyor on staff.
What do I need to use it?
Microsoft Excel on a computer. The free calculator on this site works on any phone.
Are prices and rates included?
The kit includes sample rates so you can see how each sheet works. They are examples only. You replace them with your own current prices before using any figure.
Can I use it outside Jamaica?
Yes. You set your currency and units once and every sheet follows. The free calculator works in feet or metres and with the common block sizes.
