Connect your books, payments, banking, and comms in 60 seconds. We read from your accounting system and write back payments. Everything else stays in the apps you already pay for.
Status means what is wired today. Some integrations need production credentials swapped in before they collect real money. Paystack is live for Nigeria, Ghana, Kenya, and South Africa. Stripe is test-mode for US/UK/AU/CA until live keys are added.

How it works
60 seconds to your first synced invoice.
1
Pick a provider
Click Connect on any integration card. We open the provider's official OAuth flow — not a fake form.
2
Authorize the scopes
You see exactly what we're asking for. Most providers let you scope to a single company or org.
3
We pull a snapshot
Initial sync takes 10-30 seconds for typical A/R volumes. Older data is paginated in the background.
4
Dunning kicks in
New overdue invoices automatically enter your dunning sequence. You can pause, edit, or override anytime.
