Four o'clock is rarely a good hour to be awake, and Dave Bonta's "Invoice" is built around that small, bleak window of the night. In nine short lines, a sleepless speaker settles accounts, imagines other bodies tossing in the dark, and asks a question that goes unanswered. The poem never says what the debt is. Its central idea seems to be that insomnia turns the mind into a ledger, where whatever you have put off, forgotten or failed to pay comes due at the hour when you are least able to bargain.
The title sets the terms. An invoice is a demand for payment, yet the poem's first sentence makes the speaker both parties to the transaction: "I even accounts / with myself." The verb is unusual. "To even" is not how we normally talk about bookkeeping, but it echoes "get even," so the settling of accounts carries a hint of score-keeping and grievance. The line break helps. "And I even" briefly sounds like the start of some other thought ("and I even…"), and then "accounts" lands, turning the sentence into an audit. The speaker is creditor, debtor and auditor all at once, which is exactly the loneliness of a mind arguing with itself in the small hours.
Then the pronoun changes: "Our heads roll / like ice on the shore / or the poor in / their warren." The shift from "I" to "our" is quietly startling. The private insomniac joins a crowd, and the comparisons pull in two directions. Ice rolling on a shore is cold, heavy and aimless, moved by forces it doesn't control. "Heads roll" is also an old idiom for punishment and dismissal, so the phrase carries a faint guillotine shadow beneath the shoreline picture. Then come "the poor in / their warren," a crowded, burrowed place, the human version of a rabbit's tunnels. The line break after "in" leaves the poor briefly suspended before the dwelling arrives. Reading the sentence as a whole, I take the heads to be turning restlessly on pillows, the way people toss in cramped, shared sleeping quarters. The poem doesn't spell this out, and the ambiguity suits it. Money, hardship and sleeplessness all seem to belong to the same bill.
The question that follows, "Where / is the house I forgot?", is the strangest moment. The break after "Where" makes the speaker hesitate before asking. The house could be a dream-house, a former home, or something owed that slipped out of the books. The poem gives no answer, and that is the point. "Forgot" is an accounting term of a kind, since a forgotten item is an uncounted one. It also sounds like loss, as if the mind keeps a property it can no longer find the door to.
The last line reverses what we expect: "I light a room / to scare away sleep." Normally people light a room to chase off darkness or fear. Here the speaker treats sleep itself as the thing to be frightened off, perhaps because sleep would bring the forgotten house back in dreams, or because sleeping would mean abandoning the audit unfinished. The verb "scare" makes sleep sound like a small, skittish animal, which fits the burrow image just before it. The poem ends on the action rather than a resolution.
The form is lean free verse with no rhyme scheme, and the sound is held together more subtly. The long "i" returns in "I," "ice," and "light," and "shore" and "poor" sit close enough to feel like a slant echo, depending on how you say them. Lines are short, mostly two or three beats, and enjambment breaks them at awkward points ("the poor in," "Where"), so the reading keeps catching, much as thought does at that hour. The sentence types shift too: a flat statement, an image, a question, an act. That gives the sense of a mind moving from bookkeeping to dread to bare reaction.
What makes "Invoice" worth reading is how much it holds in so little space. It takes the familiar experience of lying awake and finds an economic language for it, then lets that language open outward to the poor, and finally closes the door on any comforting answer. The poem doesn't explain the debt, and that leaves readers free to supply their own.
