For UK small businesses and accounting firms

Supplier invoices become Xero draft bills. No typing.

Each account gets a private inbox. AI extracts the figures, applies your supplier codes, and — below your threshold — pushes a draft bill into Xero. Authorising stays in the practice.

How it works

Envelope to Xero draft, in four steps.

Capture

Forward invoices to your BillFlow inbox. Every account gets a unique address. Prefer to drag files in? Bulk upload up to 25 PDFs or photos at once.

Extract

AI reads every line in seconds: vendor, invoice date, due date, line items, VAT and totals. Duplicates are flagged. Per-supplier rules apply your nominal codes and tax rates.

Review

Only when you want to. Small bills flow straight through. Set a threshold — e.g. anything over £500 — and BillFlow Ai holds those for a side-by-side check.

Sync

Approved invoices are pushed to your Xero organisation as fully-coded draft bills with the original PDF attached — ready for your final approval in Xero.

Why practices use it

Fewer keystrokes. The same control.

A private address

Every account receives its own nine-character alias at in.billflowai.co.uk. Have suppliers send bills there, or forward from Gmail, Outlook or your phone.

Printed totals win

Discounts and carriage throw line-item maths. BillFlow Ai keeps the figure printed on the invoice and flags the difference.

Drafts only

Nothing is authorised in Xero from BillFlow Ai. The practice stays in control of posting.

Xero organisation sync

Connect once. Draft ACCPAY bills land coded, with the source PDF attached. CSV export remains as a fallback.

Pricing

One monthly plan. A fortnight to try it.

Capture, extraction, supplier rules, review thresholds and Xero draft sync are included. CSV export remains as a backup.
