Plans that grow with your invoice list
Every plan runs the same system. The four-stage campaign, the reply reading, the guardrails, the audit trail. The only thing that changes is how many invoices you can have running in a month.

Every plan includes
None of this is held back for a paid tier. Upgrading buys room, not features.

- A four-stage reminder campaign that stops itself the moment you mark an invoice paid.
- AI reads every reply. A promise to pay pauses the campaign on its own; a dispute gets flagged for you.
- The firm notice and the last reminder wait for your approval before they go out.
- Business-hours sending, at least 7 days between messages, a banned-word filter on every send, and a one-click opt-out in every email.
- Forward a PDF or upload it. The client, amount and due date are read for you and shown before anything sends.
- Client replies come back to InvoiceHelix, which reads each one and shows it on the invoice, with delivery tracking on every message.
- A CSV export of your invoices, settlements and full audit log, any date range.
- A Stripe link for clients who want one, or mark it paid yourself when a check, wire or ACH lands.
- One audit trail of every send, reply, pause and settlement.

How billing works
An invoice counts when you start its reminders, not when you upload it. Reviewing the extracted fields costs nothing.
Paid plans bill monthly or yearly in advance through Stripe and renew until you cancel. Yearly costs ten months and your invoice allowance still resets every month. Cancel any time from your billing settings: you keep access to the end of the period you paid for, and there are no partial refunds for unused time.
If you reach your plan’s limit, InvoiceHelix asks you to upgrade before you can start another invoice. It never charges you without asking. Price changes come with at least 30 days’ notice.
The full terms are in the Terms of Service.
FAQ
- Is Free a trial?
- No. Free is a plan, not a countdown. It stays at 2 invoices a month for as long as you want it, and it never asks for a card.
- What counts as an invoice?
- One you start reminders for. Forwarding a PDF, checking the extracted fields and fixing anything wrong costs nothing. An invoice counts against your month the moment you start its reminders.
- What happens when I reach the limit?
- InvoiceHelix asks you to upgrade before you can start another invoice. It never charges you without asking. Campaigns already running keep running.
- How does billing work on the paid plans?
- Monthly or yearly, in advance, through Stripe, and it renews until you cancel. Yearly costs ten months, so two months are free, and your invoice allowance still resets every month. Cancel any time from your billing settings. You keep access to the end of the period you paid for, and there are no partial refunds for unused time. Price changes come with at least 30 days’ notice.
