Paid by the city

ISI CONTRACTING INC

The city's published checkbook records $40,616,194 paid to ISI CONTRACTING INC across 811 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.

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.
