Help & Support
Quick answers to the things people ask most. Still stuck? We're a real person away.
Your account
How do I view my account?
Sign in, then click Account in the top-right menu (or the menu button on mobile). Everything — your plan, billing, business details, saved quotes and invoices — lives there.
I can't find my account / I'm not signed in.
Go to the sign-in page and enter the email you signed up with. You can sign in with a password, or tap “email me a sign-in link” and we'll send a one-tap link — no password needed.
How do I manage my business details?
Under Account → Edit business profile (or the business page). Add your company name, logo, VAT number and payment details once, and they appear on every quote and invoice automatically.
How do I change my email address?
Email us at contact@builder.tools from the address on your account and we'll switch it over for you.
The tools
Are the tools free?
5 practical calculators are free forever, no account needed — Concrete, VAT & CIS, Roofing, Paint and the Unit Converter. The full set of 60 tools, AI documents, unlimited quotes and cloud sync come with Pro at £9/month.
How do I save my work so it follows me between devices?
With a Pro account, your quotes, invoices and settings save to your account automatically and sync to any device you sign in on. Look for the “Save” and “Saved” buttons on the quote and invoice tools.
How do I send a quote to a client?
Build a quote, hit Send to client, and enter their email. They get a private link to view and accept it online — and you're told the moment they open it. Accepted quotes convert to an invoice in one click.
Billing & subscription
When am I charged?
New Pro sign-ups get a 7-day free trial — nothing today. If you don't cancel before the trial ends, it renews at £9/month. Your exact trial-end date is shown on your Account page.
How do I change my card?
Account → Manage billing opens Stripe's secure portal where you can update your card, view past invoices, or cancel — a couple of clicks, no lock-in.
How do I cancel?
Same place: Account → Manage billing or cancel → Cancel subscription. Cancel during your trial and you won't be charged a penny.
Can I get a refund?
We offer a goodwill refund within 7 days of your first payment, plus your statutory rights — the full details are in our Cancellation & Refund Policy. Email contact@builder.tools with your account email and the reason.
Still need a hand?
