Advanced Accounting Reasoning
Every question. Reasoned.
Every answer. Grounded.
Reasoning built for accounting and tested on our own benchmark. Every answer reasoned across the full ledger and traced to the transactions behind it.

From numbers to advice
Built for partners who advise on the numbers. Deep on every client, and every client read against the rest.

Any question. Answered.
Ask the way you'd ask a senior accountant who knows the client inside out. Answers traced to the transactions, written up for the partner conversation.

Every movement. Explained.
Every variance traced to the transactions behind it, and trends flagged from the client's full history long before they reach the year-end.

Plans. Modelled.
FP&A for every client. Budgets from the books, actuals tracked against them, and base, bull and bear cases for a new hire, a price change or a second site.

Clients. Benchmarked.
Read any client against your whole client base. Margins, cost ratios and working capital, compared across every client in a single question.

2) Ask & Explore
Ask in plain language.
"Why did margin move this quarter?" "Which suppliers drove the cost increase?" "What does cash look like in six weeks?" Ask anything, and every answer shows the transactions behind it.

3) Model & Forecast
From a question to a forecast.
Ask what happens if supplier payments move by two weeks. Build base, bull and bear cases, and turn any analysis you like into an agent in the month-end workflow.

4) Test & Trust
Tested before it touches the books.
Our research team of PhDs in AI and machine learning built Sumary's own benchmark of accounting tasks. Every model is tested against it before it touches a client's books, and each task goes to the model that does it best.
