The bits of the job you do not get paid for, done

  • No more “I never got it”

    Every time the customer opens your quote or invoice it is counted and timestamped, so you know whether to chase or wait.

  • Quotes that become invoices

    Send a quote with an Approve button. When they say yes, one tap turns it into the invoice, with a deposit request if you want the materials covered up front.

  • Send it from the van on WhatsApp

    Quotes, invoices and payment links go to the customer's WhatsApp in one tap, from your own number, with your logo on them.

  • Chase without the awkward call

    Reminders go out before and after the due date in your words. Pick the schedule once and forget it.

How it works

Three steps. That's it.

  1. Step 1

    Send the invoice

    Pick the client, add the job, press Send. It goes by email or WhatsApp with your logo on it.

  2. Step 2

    Your client pays

    One tap to pay by card or bank from the invoice. The money goes to your own account.

  3. XeroQuickBooksStep 3

    Your 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 assistant

You:

“invoice Mrs Ashby £450 for the hallway”

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.

Questions

Things people ask

Can the assistant send an invoice without me?
Not unless you allow it. By default an assistant creates drafts, gives you a link to review, and must confirm with you before anything is sent. If you would rather yours just sent when you tell it to, turn on Assistant sending in Settings → API & integrations. You can also connect with read and write permission only, so sending is never available to it.
Which assistants work with Kwikbill?
Claude (claude.ai, Claude Desktop and Claude Code), ChatGPT (connectors or a custom GPT) and Microsoft Copilot through Copilot Studio, which supports MCP servers. Anything else that supports MCP servers or OpenAPI actions can connect too. The steps are in Connect an AI assistant.
Do I have to use an AI assistant?
No. Kwikbill is a complete invoicing app on its own, on the web and as an app on your phone. The assistant connection is there when you want it.
What does it cost?
Nothing for the free first month. After that it is £14.95 a month per business, UK VAT included, or £9.95 a month, for good, once a friend you referred has subscribed. A friend who uses your code pays £9.95 for their first three paid months. Extra businesses on the same account are 10%, 15% and 20% cheaper. Cancel any time. Businesses in Australia, the US, Canada and New Zealand pay A$14.95, US$9.95, CA$14.95 or NZ$14.95 a month, with the same multi-business discount, by a card issued in their own country.
Where does the money go when a client pays?
To your own Stripe or GoCardless account, which you connect in Settings. Kwikbill never holds client money. Card payments cost 2.4% + 20p for UK cards and bank payments 1.4% + 20p. Those are all-in rates, Kwikbill's share included, deducted before the money reaches you; there is nothing else to pay.
What can a connected assistant see?
Only the business you chose when you signed in, and only within the permissions you allowed. You can see every connected app in Settings → API & integrations and disconnect it at any time.
Can I move over from Invoice2go?
Yes. Export your data from Invoice2go and import it in Settings → Import data; clients can also come in from a CSV file.
