Bookkeeping in the United States
We run a monthly close tailored to your footprint: invoice controls, bank/credit-card reconciliations, prepaids/accruals, fixed asset register, and support schedules for tax and audit.
US GAAP: monthly close & year-end
Trial balance, P&L and balance sheet under US GAAP with policy memos as needed (revenue, leases, inventory, deferred taxes). Our US GAAP guide highlights common SME/subsidiary topics.
Cash-basis accounting (US)
For eligible entities we operate cash-basis books and plan the transition to accrual as you scale. Details in our cash-basis guide.
IFRS & group reporting
We maintain US GAAP ledgers with mapping layers, build reconciliation bridges, and prepare group packs to your calendar. See our group/IFRS overview.
Tax hand-off: IRS & states
Books power federal (1120/1120-S/1065), state income/franchise, and sales/use tax — with clean trial balances and workpapers for a fast filing process.
