Adopt AI is accounting and bookkeeping software built around AI agents instead of manual checklists. Most finance teams still spend the first two weeks of every month matching bank lines to the ledger, chasing receipts, coding bills, and explaining variances. Adopt hands that work to agents and gives people back the review. What the agents do: Daily bank, credit card, AP and AR reconciliations Transaction categorization and journal entry posting Flux and variance analysis with written explanations Monthly financial statements and close checklist tracking How it fits in: Adopt sits on top of QuickBooks, your ERP, your banks, and your bill-pay tools, or works on its own if you are starting fresh. Agents use APIs where they exist and work through the user interface where they do not, so older systems and bank portals are covered too. Controls stay with your team. Every agent action carries a record of what it did and why, and judgment calls stop with a named person who approves them. Small businesses can start on a free plan; growing and enterprise finance teams can run Adopt in the cloud, a private VPC, or on premises.
