We ship updates regularly.
Here’s what’s new and improved across Mainspring.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- New
Delete your own account
Need to leave? You can now delete your account end-to-end from Settings without emailing support.
