Is SBS Bank supported?

Yes. SBS Bank connects through Akahu, the New Zealand open banking platform, so you can link your accounts and start syncing in minutes.

How often does SBS Bank sync to Zerosum?

Syncs are event-driven: Akahu notifies Redbark via webhooks and regular refreshes when new SBS Bank data is available, and your Zerosum updates soon after, within a few hours of a transaction posting, with no fixed polling schedule.

Is my SBS Bank connection read-only?

Yes. Akahu connections are read-only. Redbark can read transactions and balances, and can never move money or change your SBS Bank accounts.

Does Redbark store my SBS Bank data?

No. Redbark uses a pass-through architecture: your SBS Bank transactions are proxied live to Zerosum. We store consent records, encrypted tokens and minimal account metadata, never transaction amounts, descriptions or balances.

Is Redbark independently security tested?

Yes. Redbark was penetration tested in July 2026 by Project Black, a CREST-accredited Australian security firm, covering the web app, REST API, MCP server and admin console. The test returned zero critical and zero high-risk findings, and every finding raised was remediated and confirmed closed on retest.

Which Zerosum plan supports SBS Bank sync through Redbark?

Zerosum’s bring-your-own-provider bank sync is included with Plus and Pro, including the Pro trial. Redbark Developer is 30% off while your Zerosum connection stays active.

Will Zerosum duplicate my SBS Bank transactions?

Zerosum runs SimpleFIN imports through its normal review, matching and duplicate-prevention flow. You control which SBS Bank provider accounts are linked to each budget account.
