FOR UK BUILDERS

Off the tools.
Off the paperwork.

Extensions, refurbs, fit-outs, new builds. Qenn handles the quoting, the invoicing, the chasing, the customer records. You handle the work. All on the WhatsApp you’re already using.

You didn’t get into
building to do admin.

Multi-day jobs mean multi-day quoting. Materials lists, supplier prices that move every week, labour estimates, contingency, VAT. By the time you’ve costed an extension properly, three days have gone, and the customer’s gone with whoever quoted on the Tuesday.

Then it’s invoicing the last job, chasing the one before, and trying to remember which sub did the soakaway at Number 12 last spring.

A 2026 survey of UK small-business owners put it at ten working weeks a year lost to admin. For a small firm at £65/hr, that’s over £25,000 of unbillable time. Not hypothetical. Not the future. Right now.

The whole job,
on one WhatsApp number.

01 / QUOTE

Site photo to drafted quote

Photo of the extension footprint, the loft, the back garden. One line of scope. Qenn drafts a structured estimate: groundworks, structural, first fix, second fix, plant, materials, contingency. Edit on the phone. Send same evening.

02 / SCHEDULE

Diary and customer confirmations

Qenn checks the calendar, books the slot, confirms the site visit with the customer on the same WhatsApp thread. No double-bookings. No “I’ll text them later.”

03 / INVOICE

Voice-note to PDF invoice

Job done. Voice note from the cab. Qenn drafts the PDF - labour days, materials, retentions, VAT. Customer has it before you’ve dropped the keys back.

04 / CASHFLOW

Payment chasing on autopilot

“Chase the three overdue invoices.” Three polite reminders go out, written in the same tone you’d write yourself. You review each. Nothing goes out without your OK.

Plays nicely with
Xero, QuickBooks and Sage.

Push invoices and customer details to Xero or QuickBooks automatically. Your accountant gets the data they need without you typing anything twice. Sage integration on the roadmap. HMRC Making Tax Digital coming Q3 2026.

Setup: about as long
as making a brew.

STEP 1

Add as a contact

You get a dedicated WhatsApp number. Save it to your phone like any other contact. Done.

STEP 2

Text it naturally

“Quote the kitchen photo I just sent.” “Chase the Henderson invoice.” “When am I free Thursday?” No app to learn. No dashboard. No new login.

STEP 3

Qenn drafts. You approve. Nothing goes out to a customer without your explicit OK. Always.
