Adfin

Adfin is a London-based fintech that operates a payments and credit-control platform aimed at helping small and mid-sized businesses get invoices paid on time. The platform consolidates direct debit, card payments (including Apple Pay and Google Pay, and card-not-present payments taken over the phone), open banking and bank transfers in a single interface, with automatic reconciliation of received payments back to accounting systems. If a payment fails, Adfin retries at no charge and can automatically send an alternative payment link or fall back to card, and merchants can pass card fees on to paying businesses instead of absorbing them. Settlement is daily on weekdays, with the platform's fee billed separately so the amount received matches the invoice.

The second product area is credit control. A single dashboard shows every invoice, customer and past or planned action, with custom statuses, activity logs and notes. Chasing can be configured manually or delegated to AI agents that adapt the timing and channel per customer across email, WhatsApp and SMS, sent in the merchant's branding and from the merchant's own email domain. Additional tools include customer statements, automatic late fees, instalment plans and partial payments. Adfin is a certified Xero and QuickBooks app, syncing invoice data, statuses, payments and credit notes, and connects to other practice management or in-house systems via API through a component it calls Adfin Bridge. Invoices can be created from PDFs, CSV, Excel and image files, and an embeddable payment portal is offered for merchant websites. In-person card acceptance via an Adfin app is listed as forthcoming.

Following its Series A, the company describes its direction as an "agentic finance platform" for money movement: owning both the underlying payments infrastructure and the agentic workflows layered on top, automating repetitive finance-team tasks while keeping decision-making, auditability and control with human users. Announced expansion areas include end-to-end cashflow management beyond invoice payments.

Founding story

Adfin was founded by Tom Pope and Ciprian Diaconasu to address persistent late payment among UK businesses. Pope, co-founder and CEO, spent more than a decade building payments infrastructure at Worldpay and at Tink, which Visa acquired for $2.2bn; Diaconasu was the founding engineer at Mambu, the banking platform that reached a $5.3bn valuation and whose customers include N26 and Tide.

Business model

Adfin sells a self-serve and demo-led SaaS-plus-payments platform to businesses and to accounting and bookkeeping practices, monetising transaction volume rather than seats. There are no monthly or minimum fees, no minimum contract length, and unlimited users and payments; the core credit-control platform is free, with revenue arising when payments are collected or advanced agent features are used.

Standard payment collection is priced at 1.0% + 20p per transaction, with the percentage fee capped at £4 for direct debit and bank payments; card payments from business cards are free to the merchant if surcharged to the payer. Enhanced credit control (agent-optimised chasing, late fees) costs 0.3%, charged only when used, while standard credit control with unlimited chasing agents is free. Supplementary fees apply for premium cards (+1%), super-premium cards (+2%), phone card payments (+0.5%), chargebacks (£15 per case), direct debit amounts above £2,000 (+0.30%) and use of the merchant's own name on bank statements via Adfin Custom (£36/month). Where a late fee is paid, the merchant receives the interest and Adfin the fixed compensation amount. Custom pricing is offered above £200k monthly processing volume.

Traction

The website states Adfin is trusted by more than 2,500 finance teams, while May 2026 press coverage reported more than 1,500 UK businesses on the platform. Adfin says customers are paid roughly seven times faster than the UK average, with 9% of invoices paid late versus a cited 63-65% UK late-payment rate, and claims about £30k saved in working capital and credit-control costs and 80+ hours saved monthly versus manual credit control for a mid-size business. A published customer case study on accountancy firm Gascoynes cites debtors down 10% and late payments down 39%; an Adfin customer at accounting practice Steve Pye & Co reported an approximately threefold reduction in its late-payment rate.

Latest developments

On 12 May 2026 Adfin announced an $18m Series A led by Index Ventures with participation from Visionaries Club and new individual investors Stéphane Kurgan (former COO of King) and Andrey Khusid (founder of Miro), taking total funding above $30m. Proceeds are earmarked for expanding the product into end-to-end cashflow management, hiring across engineering and sales, and preparing for international expansion. The first product from this direction is "customer agents," a credit-control feature automating late fee calculations and per-customer reminder sequences.
