FAQ about this system

Does it work in Excel and Google Sheets?Both. Open it in Excel 2016 or later / Microsoft 365, or upload it to Google Drive and open it with Google Sheets

Do I need to be good at Excel?No. Fill in the white cells only; dark cells are formulas, and a 5-step guide is inside the file

Can I change the business name and address on the forms?Yes. Edit them once in Settings and every form updates

How do I clear the sample data?Delete only the white cells on the data tabs; formulas and forms stay in place

How much data can it hold?Up to 300 projects and 3,000 BOQ lines, tested with full tables and no formula errors

Can I print or save the forms as PDF?Yes. Forms are set up for A4; pick the document number and print or save as PDF

What happens if I type the wrong kind of value?Number and date cells are validated and show a message, and formulas are guarded against error values

How do I build a BOQ?Pick items from the price list and enter quantities; material and labour rates are pulled in and your markup added

Do quotes handle VAT and withholding tax?Yes. Switch VAT and 3% withholding on or off in Settings; both show on quotes and invoices

How many installments can a job have?As many as you need. Enter a percentage per installment and the amount and status are tracked

Does it warn about late jobs?Yes. Projects shows "past due" and "over plan" when spending runs ahead of progress
