Said once on site. Back as branded PDFs — schedule, quote, invoice — to check, sign and send. Every one drafted at your rates, in the WhatsApp you already use.
Talk the board as you test it. Every defect comes back worded properly, coded C1/C2/C3, with the regulation cited — laid out like the model forms you already sign.
“Quote the fixes.” The remedials price straight off the defects you found — your day rate, your markup, VAT handled, 30-day validity. Or quote any job from a single voice note.
Say “invoice it” when the job’s wrapped. It goes out with a card-payment link, and your customer pays in the same WhatsApp thread they got the quote in.
Every customer, job and document kept. “Send the Hendersons’ EICR from March.” “What’s still unquoted this week?” Just ask — no folders, no searching.
