Most client e-mails in an accounting firm repeat. "How much VAT do I pay this month and by when?", "What is the payroll tax and social security amount for the staff?", "Send me the invoice for April", "Have you filed the return yet?". The accountant opens the client's data in SAP Business One or Sage, looks at the VAT return and the payroll filings in the tax and social security portals, retypes the amounts into an e-mail and adds the deadline from memory. For ten clients that is manageable, for a hundred it is several hours a day, and under time pressure the wrong amount gets typed or the wrong client gets the answer. At the end of the month each client still needs a summary of what to pay and what is missing, and often it never gets written.
The assistant prepares the draft and the accountant sends it. It reads the accountant's Outlook mailbox, recognises recurring client enquiries and, before the accountant opens the e-mail, prepares a reply from that client's data in SAP Business One or Sage: the VAT payable according to the approved return, payroll tax and social security contributions from the payroll register, a copy of the invoice for the firm's services, and it takes the deadlines from the filing calendar for VAT returns and payroll filings, not from memory. If a client asks something that is not in the data, for example whether it is worth registering for VAT, the assistant writes no draft and flags the e-mail for the accountant. On close day it prepares a summary e-mail for each client: amounts due and deadlines, returns filed, documents missing. The accountant sees all drafts in Outlook as unsent, reviews the amounts, corrects them and sends; nothing goes to the client without them. We deploy with Claude through Amazon Bedrock in an EU region: clients' accounting data is processed in the EU, is not used to train models, and every draft and accountant decision is logged in line with GDPR. We connect to SAP Business One and Sage through an API or export, but not to the tax authority's or the social security authority's portals: deadlines come from a public calendar, and the returns and filings are submitted by the accountant.
