What goes wrong
on a normal job.
01
You sent the quote on WhatsApp. They didn't reply. You can't remember the price.
02
You wrote the invoice on a notepad. You can't read your own handwriting.
03
Your accountant uses a desktop tool you don't have. The deposit's already late.
Four tools.
One toolbox.
No dashboards. No "workflows". The four things a sole-trader actually does between the call-out and getting paid — and nothing else.
Invoice on completion
One tap turns the accepted quote into an invoice. Numbered, VAT-correct, ready for the accountant.

ON THE JOB
Designed for someone whose phone has paint on it.
Big tap targets. Heavy contrast. Numbers you can read in direct sun. Works on the bench, in the van, on the scaffold. Loses signal? Keeps writing. Reception comes back? Sends the quote.

// That's a tank of diesel and a weekend away. Every month.
Three blueprint steps.
From an unsaved phone number to a paid invoice. Read it like a drawing — top-left to bottom-right.
Add a client
Snap a job photo, drop an address, save. Or import from the call log. Two taps, you're done.
Build a quote
Line items, materials, labour, VAT — all sane defaults. Margin auto-calculated. Numbers tradesmen actually use.
Send & invoice
Send the PDF by email, WhatsApp, or hand the phone over for an in-app signature. Convert to invoice the second it's accepted.
The receipt.

Common questions.
Straight answers.
DOC · MARGINTAP / FAQ / 1.09 ITEMS · LAST REV 24.05.26
Does it work without internet?
Yes. Quotes and invoices write to local storage. As soon as you hit reception they sync and send. The van's basement, the cellar boiler room, the lift shaft — all fine.
Can I export PDFs?
Every quote and invoice generates a PDF. Email it, WhatsApp it, AirDrop it, hand the phone over. No watermarks on PRO.
What about VAT?
Per-line VAT, reverse charge, zero-rated, exempt — all supported for PL, DE, IE and UK rules. Set defaults per client; override per item. Accountant gets a clean export.
Can my crew use it too?
PRO covers one trader. Crew seats are €4/seat/mo. Apprentices read-only by default. The boss sees every quote.
Will it work cross-border?
Yes — that's the whole point. Quote a Polish client in PL, deliver the invoice in DE to their German office, send the English version to their UK procurement. One job, three documents, your VAT number on each.
Does it talk to my accountant?
CSV, XLSX, and direct integrations with the most common Central-European accounting tools shipping at launch. If yours is missing, tell us — the list grows weekly.
What if I want to leave?
Export everything in one tap. ZIP of every PDF plus a CSV of clients and balances. Cancel from the app. No "are you sure" dance.
Is my client data safe?
Encrypted at rest and in transit. Hosted on EU servers (Frankfurt). GDPR-compliant. You own your data, full stop.
Why €9.99 and not €29?
Because tradesmen aren't VCs. The number is the number. We'd rather have 100,000 sole-traders than 500 agencies.
Can I quote a client in one language and invoice them in another?
Yes. MarginTap supports EN, en-GB, PL, DE, FR, IT, NL and PT on the same job. Quote a Polish-speaking client in PL, deliver the invoice in DE to their German office, send the English version to UK procurement — one job, three documents, the same VAT number on each. No other invoicing app for tradesmen does this.
