— For plumbers & heating engineers · UK

Invoice the call-out before you leave. Quote the boiler job the same day.

GlideQuote is the phone-first quoting and invoicing app for plumbers and heating engineers: a Quick Quote in three fields for the small stuff, a full quote with deposit and stages for the boiler swap, and a VAT invoice the customer can pay from their phone.

Why plumbers use it

Built for a day of call-outs and one big install

Deposit, then stages PRO

Take a deposit on the boiler or bathroom job and split the rest into stages with due dates. Mark each stage received; the balance updates itself. Refundable security deposits stay outside VAT.

Quote → invoice in one tap

Small job? Quick Quote is three fields. Accepted? The invoice is made from the quote — nothing retyped.

VAT right first time

VAT-registered? Your VAT number, rate and totals appear on every invoice automatically. Not registered? A clean, compliant invoice without VAT lines — and you switch VAT on the day you register.

Saved items & clients

Call-out fee, hourly rate, parts mark-up, “replace cylinder”, “power flush” — save them once, add them in two taps.

Site visits & call-backs PRO

Book the survey and the return visit against the job; they sync to your phone calendar and remind you.

Overdue chasing

Home shows what’s outstanding and what’s overdue; from any unpaid invoice, Remind client sends a ready-written reminder — amount due and your bank details — by WhatsApp, SMS or email.

How it works

From call-out to final payment

  1. Price it on site. Quick Quote for the leak; a full quote with deposit and stages for the boiler.
  2. Send the PDF from the driveway. Share by WhatsApp, email or LINE with your logo and terms; the customer gets a proper document, not a text message.
  3. Accepted → invoice, schedule attached. Convert the quote in one tap; the invoice carries the deposit and stages, with your bank details on it.
  4. Mark each stage received. Deposit, then each stage as it’s paid; the running balance is always visible.
  5. Issue the receipt. Record part-payments or the balance; a receipt PDF is one tap.
Common questions

Plumbers ask us

Can I invoice a call-out on the spot?
Yes. New invoice, one saved line item, your bank details are already on it — send the PDF by WhatsApp before you drive off. Free plan included.
Can I take a deposit before starting?
Yes. On Pro you set a deposit on the quote; when the customer accepts, the invoice carries it as the first stage, due first. A refundable security deposit is handled separately and is never included in VAT totals.
Does it handle VAT?
Yes, on every plan including Free. Switch VAT on once with your registration details and every invoice carries your VAT number, the rate and the totals. Not registered yet? Leave it off and switch it on the day you register.
Does it do CIS?
Not yet. CIS deductions are built but switched off until the rules are fully tested end to end. You can still invoice as a subcontractor; the deduction appears on the contractor’s statement to you, not on your invoice.
What does it cost?
Free: unlimited invoices and receipts, 3 quotes a month, your logo, VAT and bank details on every PDF, monthly and yearly reports — with a small GlideQuote watermark. Pro: £4.17 a month billed annually (£49.99 a year) or £6.99 month to month, and the first month is free.
