SendGrid Move permit applications, payments, and inspection results end to end across a legacy mainframe and a modern Salesforce or ServiceNow front end the moment they change, two-way and in real time, so nothing stalls between old and new.
Permitting spans a modern application UX, a payment processor, and a mainframe system of record that were never built to hand off cleanly.
Submissions captured in a modern portal wait for an overnight load into the mainframe of record. Applicants and reviewers stare at a status that hasn't moved since yesterday.
When a payment webhook fires twice, naive pipelines record a duplicate fee against the permit. Idempotent sync keyed on the transaction ID updates the existing fee, never doubling it.
Field inspection outcomes get stranded between the mobile app and the permit record. Queued, replayable sync guarantees pass/fail results land on the right application, in order.
Every tool Stacksync replaces is one fewer vendor, one fewer bill, one fewer integration to maintain.
Changes made in one platform automatically update across all connected systems in real time, eliminating data silos and reducing errors.
Stop building brittle API scripts. With Stacksync, you can trigger complex automated workflows using simple SQL commands.
Expose every enterprise system to your agents through a single MCP layer. Claude, ChatGPT and Gemini get production-grade tools without custom glue code.
Handle massive traffic spikes without losing a single event. Queues buffer your data during surges, ensuring strict ordering and reliable delivery.
Interact with your CRM, ERP, and payment tools as if they were just another table in your database. Say goodbye to rate limits and complex API documentation.
Transform legacy EDI complexity into simple database interactions. Stacksync automatically parses incoming EDI documents directly into your database tables.
Stacksync ships pre-built two-way connectors for the legacy mainframes, application portals, payment processors, and inspection apps permitting runs through, with idempotent writes, field-level conflict policies, and replay.

Securely connects to your systems with:
Can we add a modern front end without replacing the mainframe?
Yes. Stacksync syncs a modern Salesforce or ServiceNow UX to the mainframe of record in real time, so applicants get a new experience while the legacy system stays authoritative.
How do you stop duplicate permit fees?
Every payment sync is idempotent, keyed on the transaction ID. A retried or replayed webhook updates the existing fee on the permit instead of recording a second charge.
How do inspection results reach the permit record?
Pass/fail outcomes and notes sync from the inspection app to the application record in real time, and every event is replayable, so a result never strands between field and back office.
What happens if the mainframe is down at submission?
The application is queued and retried with backoff. When the back end recovers, it loads in order with no lost submission and no manual re-entry.
