Delaware State Checkbook - Every State Payment

Every payment the State of Delaware has made, straight from the State's own accounting system. 13.5 million payment lines, from the start of fiscal year 2018 to the last closed accounting period.

Low cost

From $0.00005 per record, down to $0.00003 at Gold. Pay only for the records you actually receive - the whole register stays queryable, you are never billed for the scan behind it.

What you get

One row per check or electronic payment, with the money side of state government attached to it:

• Who was paid - vendor name, exactly as the accounting system holds it
• Who paid - the department and the division inside it
• What for - the expenditure category, from the State's own chart
• Out of what - fund type: General, Special, Federal or Capital
• When - check date, plus the fiscal year and period it was charged to
• How much - the amount in dollars

That is the full chain: department -> division -> vendor -> category -> fund -> amount, per payment.

Filter it

• Vendor - vendor="Grainger" finds every payment to that supplier.
• Department and division - department="Education", division="Christina School District".
• Category - category="Medical Services", category="Equipment".
• Fund type - General, Special, Federal, Capital.
• Fiscal year - FY2018 through FY2027.
• Date range and last-N-days - e.g. the last 30 days of payments.
• Amount range - e.g. payments above $1,000,000.

Example inputs

Payments to one supplier - vendor is a substring match, and vendor names are free text as typed.

{ "vendor": "GRAINGER", "maxResults": 25 }

What one department buys - combine department with category.

{ "department": "EDUCATION", "category": "SUPPLIES", "maxResults": 25 }

One payment by check number - checkNumber is a substring match too.

{ "checkNumber": "0000779890" }

Where the money goes - mode=aggregate returns one count row per department; every group comes back.

{ "mode": "aggregate", "groupBy": "department" }

Or roll it up

Set mode=aggregate and get a count by department, division, category, fund type or fiscal year. Every group comes back - this mode is not cut off by maxResults.

Then follow the money

• Total state spending by department or by category, over any window.
• Every payment a supplier has received from the State, and for what.
• Federal vs. General vs. Special fund spend, side by side.
• Payments over a threshold, newest first.

Example output

One payment line - checkNumber=0000779890 returns the payment as recorded:

{

 "source": "delaware-state-checkbook",

Notes on the data, from the source

• One row is one payment line, not one check. A single check can carry several lines, one per accounting distribution.
• Check numbers are not serials for bulk runs. Payroll is stamped PAYROLL (3,446,472 lines) and purchasing cards PCA (1,678,820); the remaining lines carry a real 10-digit serial. It is a field and a filter, not a key.
• Refunds and reversals are in here. 125,268 lines are negative, down to -$51,000,000. They are real accounting entries, returned as they stand - leave the minimum amount blank to include them, or set it to 0.01 for payments only.
• Vendor names are free text as typed. The same supplier can appear under several spellings.
• check_date is the date the payment cleared, not the date the work was ordered.
