What’s new

We ship updates regularly.

Here’s what’s new and improved across Mainspring.

  1. New

    Founding Member tier + annual billing

    Lock in our lowest price forever ($19/mo or $190/yr) — only 50 spots, only at launch. Annual billing also added to Team and Business, saving you ~2 months vs paying monthly.

  2. New

    Heads-up when payment fails

    If a renewal charge gets declined, you now see an in-app banner and get an email so you can update your card before the subscription lapses.

  3. Fixed

    Invoice errors no longer fail silently

    Creating an invoice or bill with a same-day due date used to drop without warning if something went wrong server-side. You now get a clear toast explaining what failed.

  4. New

    Edit invoices after they're created

    Made a typo, need to add a line item, or want to change the due date? Edit any invoice in place instead of deleting and recreating it.

  5. New

    Custom Kanban columns

    Your board, your statuses. Add, rename, reorder, or remove columns to match how your team actually works — not a generic To Do / Doing / Done.

  6. Improved

    Manage your subscription in Stripe

    The billing page now links straight to the Stripe Customer Portal. Update your card, download past invoices, or change plans — all in one place.

  7. New

    Delete your own account

    Need to leave? You can now delete your account end-to-end from Settings without emailing support.
