Paid by the city

SOUTHERN IONICS INC

The city's published checkbook records $33,197,463 paid to SOUTHERN IONICS INC across 6,899 payment lines, from FY2018 to FY2026.

Name as the city files it — often the legal name, not the trading name. The city's budget year runs July 1 to June 30, so FY2026 means July 2025 through June 2026.

A dash means no payment to this vendor appears in that year's file. The city publishes this a few times a year, so it runs behind — the newest payments can take a few months to appear, and a fiscal year that has just ended usually isn't published at all yet. Treat the most recent year as incomplete.

A contract number is the city's master agreement; individual purchases are released against it and don't each go back to council for a vote.

Where this comes from

Every figure on this page is summed from the City of Houston's published checkbook ↗, FY2018–FY2026. PlainDocket stores the totals; the individual payments stay on the city's portal, where you can filter them yourself.

These are payments, not a budget. The same ledger carries debt payments, bank and pension transfers and accounting reversals alongside what the city bought, so adding it all up doesn't describe city spending — which is why you won't find a citywide total here. What a named vendor or department was paid is solid.
This covers what the city paid — not what a council vote approved. A contract approved years ago can still be generating payments, and money approved recently may not have been paid yet.
