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.

Frequently Asked Questions

My client doesn't like changes in technology, how can you make this transition easier?

We designed Jack to integrate seamlessly with the platforms your clients already use. They can easily send pictures of invoices and receipts through WhatsApp. There's no need for a separate mobile app download. We also support Slack, email, and soon, Microsoft Teams.

How much does Jack cost?

Jack costs £21.60 per hour, billed in 30-second increments. There are no minimum monthly time requirements or long-term contracts, so you only pay for what you need. You can onboard every client and receive personalised reporting to know the cost of bookkeeping for each client every month.

Is Jack an alternative to outsourcing bookkeeping?

Yes, Jack works 10x faster and costs 3-4x less than outsourcing. By implementing Jack in your practice, you retain control of data and reporting consistency and can improve your EBITDA.

Can Jack be implemented now?

Yes, Jack is currently in Beta, which means we will work with you to implement and monitor Jack's initial training. You can join by booking a demo on our website, where we'll also verify that Jack can integrate with your practice apps and team.

What happens to my staff - does Jack replace them?

No, Jack handles 90% of the extraction, including line items, VAT, and account codes. Your team will validate Jack's work until trust is established. This will free up your team's time for client analysis and additional training, potentially fast-tracking their careers.

How does Jack help my practice make more money?

The time saved by your staff can be used in two ways: taking on more clients without increasing headcount, or fast-tracking your team's careers by allowing them to focus on higher-margin accounting and advisory work.
