AI that works for your business
Powered by Claude, our AI features save you time and reduce manual errors across your bookkeeping workflow.
AI Accountant
Ask questions about your finances in plain English. Get instant answers about cash flow, overdue invoices, profit margins, and more.
Smart Bill Scanning
Snap a photo or upload a bill. Our OCR powered by Google Cloud Vision and Claude extracts vendor, amounts, line items, and dates automatically.
Auto-Classification
AI automatically assigns expense accounts to bill line items. It learns from your corrections and gets smarter over time with your custom rules.
Contact Matching
When scanning bills, AI matches vendors to your existing contacts using fuzzy matching. New vendor? Create a contact right from the bill form.
Bulk Bill Upload
Upload a stack of bills at once. Each file is processed through OCR, classified, and entered as a bill automatically. Review and approve from your inbox.
Review Inbox
A central inbox for all pending tasks — bills to review, payment reminders, and processed emails. Approve, edit, or dismiss with one click.
Put your bookkeeping on autopilot
Build workflows that handle the repetitive parts of bookkeeping, so you can focus on running your business.
Payment Reminders
Build multi-step reminder sequences. Send emails automatically before or after an invoice is due. Customise the subject, body, and timing for each step.
Email Forwarding
Generate a unique email address for your business. Forward bills and receipts to it — they'll be automatically scanned, classified, and entered as bills.
Classification Rules
Create rules to automatically assign expense accounts based on vendor, description, or amount. Rules are also learned from your manual corrections.
