Quotes, invoices and site reports from your phone
You’d rather be on site than doing paperwork. These apps keep the paperwork short: a quote or invoice in under a minute, a snagging report you can send before you leave the drive, and a mileage log that keeps itself.

What you need
- Quote, then invoice, from your phone
- Write a quote, turn it into an invoice in one tap when it’s accepted, and send it by WhatsApp, Messages or email.
- Record what you find on site
- SnagLine is camera first: photograph the snag, say or type what’s wrong, mark up the photo and pin it on the floor plan. It works with no signal.
- Send a report before you leave
- SnagLine makes a branded PDF with your logo and company details, grouped by room, with the fix-by dates and who is fixing each one.
- Log the miles
- Thistle Miles is built to log work drives automatically, so the journey to site is on record.
