What is Jack?

Jack is your in-house bookkeeper. It takes care of line-item accounting, VAT compliance and sets up payments. Your clients need more strategic advisory work, so manual management accounting needs to go.

10x faster than in-house bookkeeping and more accurate than outsourcing. Jack is the hybrid solution perhaps you hoped AI could be.

How Can Jack Help

How Jack can help

Jack's primary job is to take on the manual extraction, entry and initial bookkeeping for every business cost incurred.

Jack makes space for your team to upskill and take on higher margin work for your clients - or take on more clients without increasing headcount.

With Jack you can:



Clients send Jack invoices by WhatsApp, Email Fetch or Slack, then extracts and reconciles 10 invoices every 3 minutes. Simply log in and validate Jack's work before sync or send to pay run.



Jack acts like an insurance policy, checking identity, authority, budget, policy, laws and regulations in real-time for every transaction. This includes VAT and GL code compliance.



From April 2024, send supply chain payments or reimbursements to Jack to be paid. Jack knows when a payment is intended to be paid on invoice arrival so is trained to detect and prevent financial fraud.

Where it all started...

Jack's backstory


Jack was initially conceived as a payment solution for companies that preferred to pay by purchase order (PO) but had suppliers who wanted to be paid by card. The co-founders, Nicolai and Tosin, met at an accelerator in London. However, transactional accounting teams considered this a nice-to-have feature rather than a necessity.
When the co-founders inquired about the most tedious and time-consuming tasks in accounting, there was a unanimous agreement: retrieving invoices from clients, manually reconciling half of the invoice, and chasing clients to pay their bills. This revelation led to a pivot in Jack's focus.
Now, Jack is designed to be readily available wherever your clients are already working and communicating – be it email, WhatsApp, Slack, or Teams. This integration makes it incredibly simple for clients to snap a picture of a receipt or invoice and send it in, streamlining the invoice submission and reconciliation process.
