Dunning software, sometimes called collections or invoice chasing software, automates the chasing of unpaid invoices. Straightforward. But “affordable” means one thing for a two-person finance team and something completely different for a venture-backed scale-up.
This article focuses on “affordable” for a lean finance team, typically between 1-3 people. These five tools all have indications of their pricing, either on 3rd party review sites or published on their websites making a comparison possible.
What features a lean finance team needs from dunning software
Automation is the key outcome here. If you are a small finance team, you want to spend as little time as possible manually chasing invoices.
Here are the tablestakes features required:
- Emails sent automatically from your own domain
- Team collaboration to avoid duplicating work
- Integrations with your tech stack, e.g. Slack, MS Teams, CRM and webhooks
- Human-sounding emails that don’t read like a machine sent them
A couple of extras only some tools push, which a smaller team may or may not need:
- MCP server access which lets AI assistants connect to your AR data directly. LedgerUp advertises this.
- Payment functionality so customers can pay from the reminder itself. Helpful if you’re not using Stripe or similar. Upflow advertises this.
Every one of the five tools compared here includes the tablestakes features. Let’s look at how they compare on cost. For a fuller look at which features are worth paying for, see our guide to invoice chasing features and price.
What each tool would cost you
Type in your annual revenue to see the estimated monthly cost of each tool.
Assumptions. Trove is shown on its £135 plan, the closest match to what the other tools include at this level. Chaser, Trove and LedgerUp prices are published; LedgerUp is $500/month, fixed. Lunos.ai is modelled as $200/month plus 0.3% of collected revenue and we have conservatively assumed 20% of your revenue needs collecting via the tool. Upflow doesn't publish pricing, so its figure is a third-party estimate (TrustRadius) and may be out of date. Dollar prices are converted at roughly $1 = £0.79. These are estimates to show how each pricing model behaves, not quotes. Always get a current quote before deciding.
The five tools side by side
| Tool | Starting price | Pricing model | Published? | Free trial |
|---|---|---|---|---|

| Chaser | £199/month | By turnover band | Yes | 10 days |
| Upflow | ~$440/month (est.) | By ARR tier | No | Free tier, analytics only |
| LedgerUp | $500/month | Fixed | Yes | Demo |
| Lunos.ai | $200/month + 0.3% | Fixed plus % of collections | Yes | Free in Suggest mode |
What each tool costs, and who it’s for
Chaser
Chaser is a UK tool aimed and it’s one of the few in this space that publishes its prices. Plans are banded by annual turnover, starting at £199/month for businesses under £4 million and rising to £899/month for those under £100 million.
Two things to watch. The headline price steps up each time you cross a turnover band, even when nothing about how you use the tool has changed. And SMS reminders, auto-call and the payment portal are paid add-ons on top, so the real number is usually higher than the sticker. There’s a 10-day free trial.
Chaser earns its place if you want a familiar SMB tool with built-in debt collection and credit checks. We compare Chaser and Upflow feature by feature here.
Upflow
Upflow is focused on mid-market and enterprise B2B teams, often venture-backed tech companies with a dedicated credit-control function. Its strength is depth: detailed AR analytics, DSO tracking and configurable collection workflows, plus the built-in payments portal it advertises.
Upflow doesn’t publish pricing and doesn’t advertise a trial. Third-party listings on TrustRadius put it at roughly $440/month for companies up to $10 million ARR and around $880/month up to $50 million, though Upflow hasn’t confirmed those figures. There’s a free tier, but it only shows your AR data. You can’t automate any chasing on it.
For a lean finance team that mostly needs consistent follow-up, Upflow may have more features and cost than the job calls for. Here’s a closer look at how Chaser and Upflow price.
LedgerUp
LedgerUp is an AI-driven platform for B2B SaaS companies with complex billing. Its AI agent, Ari, reads signed contracts, raises invoices, chases overdue payments and reconciles cash across your CRM and accounting stack.
It publishes its pricing, starting at $500/month on a fixed plan, which makes it more accessible than its enterprise positioning suggests. It’s also the tool that advertises MCP server access, letting AI assistants connect to your AR data directly.
The product is still built around complex SaaS billing and full contract-to-cash automation. If what you need is overdue invoices chased rather than your whole revenue operation run, you’ll be paying for capability you won’t touch.
Lunos.ai
Lunos.ai is a newer entrant, an AI “coworker” that handles two-way conversations with customers over email and Slack, following up, answering questions and matching payments. It connects to Xero, QuickBooks and NetSuite.
Its pricing has two parts: a $200/month fixed fee plus 0.3% of the revenue it helps collect. So the more it collects for you, the more you pay. Assuming 20% of your revenue needs chasing, a £4 million business would pay around £360/month, and that figure keeps climbing as your collections grow.
It may be cost effective depending on your revenue volumes but it’s worth modelling against your actual numbers before you commit.
Trove
Trove is priced on features rather than turnover.. It’s a fixed monthly price with no user limits and no add-ons to configure. The £135 plan includes the tablestakes features mentioned above but the most basic plan is fixed at £50 / month.
It’s deliberately focused on one job: chasing unpaid invoices automatically. It doesn’t do in-house debt collection, credit checks or heavy AR analytics, so if those are central to how you work, one of the tools above will suit you better.
Trove is designed for a one or two person finance team that wants consistent follow-up without a bill that grows every time the business does. Setup takes about 15 minutes, and there’s a full 30-day free trial with no credit card required.
So which is actually affordable?
Affordability comes down to two questions: how big are you, and what do you actually need?
At a small scale, several of these look affordable. As you grow, they behave very differently. Chaser steps up through its turnover bands. Lunos rises with everything it collects. Upflow stays quote-only and points at larger teams. LedgerUp and Trove both hold a fixed price.
If you need deep analytics, an AI agent that reads contracts, or built-in debt collection, the heavier tools justify their cost. If what you need is for overdue invoices to get chased consistently, a fixed price for the core job is the cheapest way to get there.
Fixed price. No surprises.
Trove is dunning software with a fixed price that doesn't grow with your turnover. Start with a free 30-day trial with no credit card required.
Common questions about affordable dunning software
What is dunning software?
Dunning software automates the reminders that chase overdue invoices - the “dunning” process - so follow-up happens consistently without anyone doing it by hand. You set a reminder schedule once, and the software sends it on every overdue invoice. It’s often called collections software or invoice chasing software.
What’s the most affordable dunning software for a lean finance team?
It depends on your revenue and what you need, because most of these price by how big you are or how much they collect. The flattest options are the fixed-price tools: Trove (from £135/month on the plan compared here) and LedgerUp (from $500/month, though it’s built for larger SaaS billing operations). Chaser starts at £199/month but rises with turnover, and Lunos.ai charges $200/month plus 0.3% of what it collects.
Does dunning software pricing scale with revenue?
It varies by tool. Chaser bands by turnover and Upflow by ARR tier, so both step up as you grow. Lunos.ai charges a percentage of collections on top of its fixed fee, so it rises with the cash it brings in. Trove and LedgerUp are fixed, so they stay put regardless of revenue.
What’s the difference between dunning, collections and AR software?
Dunning is the automated reminder sequence around the due date. Collections software is often used interchangeably, though it can stretch to recovering seriously overdue debt. AR software is broader still, adding analytics, cash application and forecasting. A lean team usually needs the dunning piece done well and little else.
