Automated Invoice Chasing for UK Freelancers
Get Paid Without the Awkward Conversations
Executive Summary
In a nutshell
An automated invoice chasing tool that connects to Xero, QuickBooks, and FreeAgent, detects overdue invoices, and sends polite, AI-personalised payment reminders on behalf of UK freelancers and micro-businesses. The UK accounts receivable automation market is worth $298M (2025) and growing at ~13% CAGR. Late payments affect 1.5 million UK businesses with £26 billion owed at any one time — and the UK government announced its toughest-ever crackdown on late payments just 12 days ago (24 March 2026), creating a once-in-a-generation timing window. Existing solutions like Chaser start at £199/month — wildly out of reach for freelancers. There's a clear gap for an affordable, freelancer-focused tool at £9-19/month.
The Story
Meet the user
Simon is a freelance UX designer in Bristol. He loves the creative work but dreads the end of the month — not because of deadlines, but because of the three clients who still haven't paid last month's invoices. He's written the same "Just following up on my invoice..." email so many times he could do it in his sleep. One client owes him £2,400 and has gone quiet for six weeks. He knows he should chase harder, but it feels desperate, awkward, and frankly a bit confrontational. He's thought about using Chaser, but at £199 a month it costs more than some of his clients pay him.
Then he discovers ChaseBot. He connects his bookkeeping account in two minutes, and it starts monitoring his outstanding invoices automatically. The next morning, his most overdue client gets a polite, professional reminder — sent from Simon's own email address, in his tone of voice. By Friday, two of three invoices have been paid. He didn't write a single follow-up. He just got on with his work.
Scores
How does this idea stack up?
7.8/10
Large, growing market ($298M UK AR automation) with a clear underserved segment — freelancers priced out of existing tools
Acute, universal pain — 63% of freelancers wait 30+ days to get paid, 42% have missed personal bills as a result. Reddit threads full of frustration
Xero and QuickBooks have mature APIs, but multi-platform integration adds complexity. Email sending, scheduling, and AI tone need careful engineering
UK government crackdown on late payments (24 March 2026) — new mandatory interest on late payments, 60-day cap on payment terms. Creates massive awareness wave
Moderate — multiple accounting API integrations, email deliverability, AI tone generation, billing. Doable solo but not a weekend project
Strongest
Timing
The UK government's "Time to Pay Up" announcement on 24 March 2026 is the single best catalyst possible. Every freelancer in the UK is now hearing about late payment rights.
Watch out
Effort to Build
Integrating with Xero, QuickBooks, and FreeAgent APIs simultaneously requires careful architecture. Start with Xero only (largest UK freelancer base) and add others post-MVP.
Pain Point
The problem
“The worst part isn't sending the invoice, it's chasing it afterwards. That awkward 'just checking in on this invoice' email. My electrician brother-in-law said the worst part of chasing invoices for him is that it makes him feel like he's being desperate, which he hates.”
— Neil Stow, Indie Hackers (March 2026)
The pain is both financial and emotional.
Financial impact: £26 billion owed to UK businesses at any one time in late payments. 38 businesses close every single day because they aren't paid on time (GOV.UK, March 2026). 42% of freelancers have missed personal bill payments due to client payment delays. 63% of freelancers wait over 30 days to get paid. Almost two-thirds of invoices sent by UK small businesses in the past year were paid late.
Emotional impact: Reddit threads consistently describe chasing payments as "awkward," "frustrating," and "desperate." Multiple posts describe the power imbalance: "Once the work's delivered, chasing feels awkward because the power's shifted." Freelancers avoid confrontation with clients they rely on for future work, leading to passive behaviour and unpaid invoices piling up.
Systemic problem: 90% of UK businesses face payment delays. Most existing solutions are enterprise-priced (Chaser starts at £199/month). Freelancers currently cope with manual emails, spreadsheets, or just hoping for the best.
