Citizen-service portals
on one record

Keep constituent records in lockstep across legacy mainframe systems of record, Salesforce, and ServiceNow the moment anything changes, two-way and in real time, so the portal and the back office never disagree.

Where citizen portals break in production

Three reasons the portal and the record of truth drift apart.

The portal a constituent sees and the mainframe that pays them were built decades apart. Here's where the two fall out of sync.

01 - Overnight refresh

The portal shows yesterday's status

Most integrations refresh the constituent record from the mainframe once a night. Residents see a stale balance or case status and flood the call center the next morning.

LATENCY
02 - One-way feeds

Updates made online never reach the record

A resident changes their address in the Salesforce portal, but the system of record never hears about it. Field-level conflict policies decide which side wins, per field, instead of dropping the edit.

CONFLICT POLICY
03 - Mainframe fragility

A green-screen timeout loses the write

COBOL and CICS back ends time out under load and naive pipelines silently drop the update. Every event is queued, retried with backoff, and replayable so nothing vanishes.

How quickly does a portal change reach the mainframe?

Sub-second when the portal emits webhooks (Salesforce CDC, ServiceNow), otherwise 1–60s on a configurable poll against the legacy record. Nothing waits for an overnight refresh.

Can we sync without modifying the legacy mainframe?

Yes. Stacksync reads and writes through the database, API, or middleware the mainframe already exposes, so you add real-time sync without touching COBOL or risking the system of record.

Who wins when the portal and the record disagree?

You set the policy per field. The system of record can own legal fields while residents own contact details, so a portal edit and a back-office update never silently overwrite each other.

What if the mainframe is down during a citizen update?

The write is queued and retried with backoff, and every event is replayable. When the back end recovers, updates apply in order with no manual re-run or lost submission.
