Billstride

Billstride lets you draft and send invoice PDFs from Claude. Write an invoice the way you would brief a colleague: who it is for, what you did, what it costs. Client addresses, VAT IDs and your own company and bank details come from your account.

A new invoice is a draft unless you say otherwise. Drafts are free and reach nobody. Ask Claude to check one and it reads the finished page before you finalize. Finalize it when it is right, and email it when you ask. Billing the same client again takes one sentence: the last invoice is copied with its line items and you change what is different.

Invoices follow the tax rules of your country, with 25 countries covered, including reverse charge and the small-business VAT exemption, and they carry your own logo. A finalized invoice can also be downloaded as an e-invoice, ZUGFeRD or XRechnung: ask for the link.

Keep track of what you are owed: list invoices by client or date, see which are paid, unpaid or overdue, check whether an email was delivered and opened, and send a payment reminder. Keep your customer list in order too: add, look up, change and remove customer records. You can also see revenue by month and client, and export finalized invoices as a DATEV package.

There is no subscription. You pay per finalized invoice from prepaid credit, and the first invoice is free. The connection reaches your own Billstride account only; it cannot take a payment or top up your balance. Drafts can be deleted; a finalized invoice stays on record.
