Maria runs invoicing at Jumpstart on her own. Recruitment fees are large and land three months after the placement, so chasing them had become most of the job. Since using Adfin, invoice volume has quadrupled; the time she spends chasing has not.
"Given the rate that we're scaling, if we didn't have Adfin today, we'd probably have to hire a whole finance team to manage our invoices manually. Or my whole role would have to become just invoicing."
Invoice volume quadrupled. Average days late fell 73%. Invoicing is still one person's job.
With chasing, collection and reconciliation handled in one place, Jumpstart can now keep growing invoice volume in a scalable way without creating more work.
Jumpstart places people into startups. The fee is a share of the salary rather than a rate for hours, so the invoices are large. They also go out three months after the placement, once the candidate has passed probation.
By then the work is finished and there is nothing left to withhold, which makes the invoice easy for a client to leave until later.
“We spend the vast majority of our time building a good product for startups. What we don't have enough time to do is build a process to go off and just get paid.”
Matthew Sarre · Co-founder, Jumpstart
The process underneath was assembled from separate parts that did not work together.
Chasing emails were sent out through Zapier, but QuickBooks could not attach the invoice, so clients were being asked to go through their documents, find the invoice in a previous email, and then pay.
“Once a payment comes into your bank account, great, someone's paid you. But which client is it?.”
Maria · Operations, Jumpstart
By October 2025, the volume had outgrown the process. Matthew and Maria spent a week on the phone and brought in £200,000 by chasing manually. Then they went looking for something that would do it without them.
Jumpstart has not changed how they raise invoices. Adfin picks them up from QuickBooks through the direct integration, sends the reminders, takes the payment, and marks the invoice as paid in QuickBooks once the money lands.
Reminders go out on a schedule set once, by email and WhatsApp. Nobody has to start them.
Every reminder carries a payment link, with nothing for the client to set up.
“Every chaser has the invoice link attached. People are paying directly from those chasers, which is so useful.”
Maria · Operations, Jumpstart
Each payment comes back against the invoice it belongs to. Working out who had paid what went from around five hours a month to 20 minutes.
Six invoices that were already overdue when Jumpstart started with Adfin have since been paid, worth more than £50,000. Average days late fell from 23.7 to 6.4.
“Cash flow enables anything and everything. If you've got money in the bank, you're not worrying about making payroll, or paying your own invoices.”
Matthew · Co-founder, Jumpstart
Invoice volume has roughly quadrupled since Maria took the process over. The time she spends chasing has not.
“The question really becomes, as a founder who is scaling their business, whether you want to invest time in building out a process that is not core to your product, or do you want to leverage somebody else's.”
Matthew · Co-founder, Jumpstart
Jumpstart chose the second. Getting paid runs in the background now rather than being a process someone maintains, and with volume set to rise again this year, the finance team is still one person.
