Made for plasterers
The bits of the job you do not get paid for, done
Rates you price once
Save your price per square metre or per room as items and drop them onto a quote in a tap.
Send it from the van
Quotes and invoices go to the customer's WhatsApp or email with your logo on them.
Know when it has been seen
Every open is counted and timestamped, so you know whether to chase or wait.
Chase without the awkward call
Reminders go out before and after the due date in your words.
How it works
Three steps. That's it.
- Step 1
Send the invoice
Pick the client, add the job, press Send. It goes by email or WhatsApp with your logo on it.
- Step 2
Your client pays
One tap to pay by card or bank from the invoice. The money goes to your own account.
Step 3Your books are done
Invoices and payments flow into Xero or QuickBooks. Nobody types anything twice.
Use ChatGPT or Claude?
Tell it what the job was. It drafts the invoice.
Connect your assistant to Kwikbill once. Then type a line like the one here and it drafts the invoice for the right customer, with your prices on it. You check it and press Send. It cannot send anything without you.
How to connect an assistantYou:
“invoice Mr Ashby £620 for the living room”
Assistant:
Drafted. Here is the link to check it before it goes.
Features
Everything a small business needs to get paid
Built for trades, freelancers and the bookkeepers who look after them. Every feature is included with every business; there are no tiers to compare.
Pay by bank and card
Clients pay from the invoice page: by bank through GoCardless at 1.4% + 20p a payment, or by card through Stripe at 2.4% + 20p for UK cards. The money goes straight to your own account, and with your bank connected, transfers that arrive mark their invoices paid on their own.
Know when it has been seen
Every time a client opens an invoice it is counted and timestamped, and email opens are tracked too. It is on the invoice list, on the invoice itself and in the activity feed, so there is no more “I never got it”.
Share on WhatsApp
Send an invoice, quote, reminder or payment link to a client's WhatsApp in one tap. It opens WhatsApp with the message and link filled in, from your own number.
Quotes that turn into invoices
Estimates with approve and decline buttons for the client, deposit requests, and one click to convert an approved quote into an invoice.
Recurring invoices and reminders
Repeat invoices on a schedule you set, and automatic payment reminders before and after the due date, with the wording you choose.
Reports and VAT
Fifteen reports, a VAT return summary, customer ageing, profit and loss, and CSV exports your accountant can open.
Your team, included
Unlimited team members with owner, admin, staff and viewer roles. Run more than one business from the same sign-in.
An API for everything else
A documented REST API, signed webhooks for “invoice paid” and “invoice viewed”, and an OpenAPI document, for Zapier, Make, n8n or your own code.
