What works today, honestly.
Lempel is in build and not open to the public. Rather than describe a finished product, here is exactly what the application does right now. The amber markers further down are the parts that are still coming.
- Photo and text intake on a quote
- Quotes, jobs, invoices and diary
- Secure quote links customers can accept
- Your labour rate and VAT applied to the maths
- Branded PDF quotes and invoices
- EIC, EICR and Minor Works certificate drafts
One job, start to finish, without the evening admin.
Each step feeds the next. Nothing gets typed in twice.
First
Describe the job however suits you
Photos and a few lines of text. Lempel asks only what it needs to price the work, and if you correct it in conversation — make that four hours, not three — the correction sticks.
Then
A quote in your numbers, not generic ones
Your labour rate, your materials markup and your VAT position, calculated properly rather than guessed, and every line editable before it goes anywhere.
On acceptance
The job sets itself up
Accepting a quote opens the job with the scope, the original photos and the customer's details already in place. Ready for whoever is on site.
In buildA generated materials list and plan of works come later.On completion
Invoice out
The invoice reflects the work that was approved. Send it with a payment link and track what has actually landed.
All year
Receipts filed as they happen
Photograph the receipt in the merchant's car park and it lands against the right job.
In buildNot built yet. This is the next thing after the estimator.And if you're an electrician
Certificates too
EIC, EICR and Minor Works, organised, with branded PDFs for your own records.
It finds out what the job actually cost — then quotes better next time.
Because the receipts and the hours come back into the same system that produced the quote, Lempel can see where your estimates drift. Not industry averages. Your jobs.
Bathroom refit — Carter
| Measure | Quoted | Actual |
|---|---|---|
| Labour hours | 18.0 | 23.0 |
| Materials | £1,100 | £1,236 |
| Margin | 32% | 24% |
Next bathroom quote: your last four averaged 22.7 hours, so this one is built on 22 — not your old 18-hour default.
Trades who are good at the work and sick of the office side.
Quoting at 9pm
You promised it Tuesday. It's Thursday and it still isn't written. Photograph the job while you're standing in it, and read the priced version back over your tea.
Chasing your own money
The work's done and the invoice is still in the van. Raise it from the finished job the same day, with a payment link in it, and see what has actually landed.
No office, no admin help
There's nobody to hand it to. Every quote, every invoice, every certificate is you, after a full day on the tools.
What it will cost
Two plans. Start free, and move up when Lempel is doing enough of the work to be worth paying for.

Being straight with you: Lempel isn't finished. It's in build, it's being tested properly before anyone relies on it for real money, and it won't open up until it's ready. That's the reason for a list rather than a signup button.
