Summary
- Trove is credit control software that runs dunning for B2B invoices, like LedgerUp, Upflow, Chaser and Lunos: automated reminder sequences, reply handling and escalation on unpaid invoices paid on terms, not card-payment retries.
- Card dunning is a different job. Tools such as Stripe and Chargebee retry failed card payments on subscriptions. If your customers pay invoices by bank transfer, you need invoice dunning.
- Prices, checked in Oct 2026: Trove from £65 a month, Chaser from £199, Upflow about $440 (a third-party estimate, not published), LedgerUp from $500, and Lunos 0.3% of the collections it handles.
- Two pricing models dominate. Chaser, Upflow and Lunos step up with revenue or amount collected. LedgerUp and Trove charge a fixed fee.
- Two reminders do most of the work. Trove’s data shows 75% of invoices that get paid are paid by the second reminder, so the sequence matters more than the feature list.
Invoice dunning vs card dunning: which one you need
“Dunning” covers two different problems, and half the tools that rank for the word solve the other one.
| Invoice dunning (B2B) | Card dunning (subscriptions) | |
|---|---|---|
| What fails | An invoice on 30 or 60-day terms isn’t paid by the due date | An automatic card or direct debit payment is declined |
| Who has to act | A person in the customer’s finance team, who has to approve and send a bank transfer | Usually nobody, if a retry goes through. Otherwise the cardholder updates their card |
| What the tool does | Sends a reminder sequence, reads replies, logs promised dates, escalates to the account owner | Retries the payment at better times and emails the customer to update their card |
| Example tools | Trove, Chaser, Upflow, LedgerUp, Lunos | Stripe, Chargebee |
If you bill by subscription and also send invoices on terms, you may need both. Our guide to dunning for B2B SaaS when payments are already automated covers where your payment provider’s retries stop and invoice chasing takes over.
What B2B dunning software does
The core job is to make sure every overdue invoice gets followed up, without someone in finance doing it manually. For a finance team with several people chasing, these are the features that matter:
- Reminder sequences sent from your own domain, so replies come back to your inbox.
- Different sequences for different customers, for example by contract size or how overdue they are.
- Reply handling, so a customer’s “we’ll pay on Friday” pauses chasing instead of triggering the next reminder.
- Escalation, from finance to the account owner or Sales team.
- Team collaboration, so two people don’t chase the same customer.
- Integrations with your accounting system, CRM and Slack or Teams.
All five tools on this page cover the core reminder sequence. Where they differ is price, and how much they do beyond chasing.

Because three of these tools price on size, getting an accurate price depends on your revenue. Type in your annual revenue to see the estimated monthly cost of each.
Assumptions. Trove is shown on its £140 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 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.
Best dunning software for B2B invoices, compared
Trove
Best for: a finance team that wants invoice dunning and reply handling at a fixed price, however much revenue grows.
Trove prices by plan, not by revenue or users. Essential is £65 a month and includes personalised chasing emails and statements, payment plans, late fees, email bounce monitoring and debtor reporting, with unlimited team members. Integrated, at £140, adds CRM data, Slack and Teams alerts, a team board and webhooks. Advanced, at £300, adds several entities and NetSuite and Business Central.
Central to all plans is collaborating with sales. Trove helps finance bring Sales in at the right point in the process to get invoices paid. If your invoices go out through Stripe, we’ve compared each chasing tool for Stripe invoices.
Chaser
Best for: a UK mid-market finance team that wants published prices and a built-in route to debt collection.
Chaser is a UK tool and one of the few in this space that publishes its prices. Plans are banded by annual revenue: £199 a month up to £4m, £599 up to £10m and £899 up to £200m, with annual billing 10% cheaper.
The thing to watch is the band. The price steps up each time you cross a revenue threshold, even when nothing about how you use the tool has changed. We compare Chaser and Upflow feature by feature here.
Upflow
Best for: a mid-market B2B or SaaS company that wants deep AR analytics and a payment portal alongside dunning.
Upflow’s strength is depth: AR analytics, DSO tracking and configurable collection workflows, plus customer payments. It doesn’t publish pricing.
TrustRadius lists Grow at about $440 a month and Scale at about $880, and ERP Research puts those plans at up to $10m and $10m to $50m ARR. Upflow hasn’t confirmed the prices. The free Discover plan shows your AR data but doesn’t chase (ERP Research).
If what you need is consistent follow-up, Upflow may have more features and cost than the job calls for. Here’s what Upflow costs and how five alternatives compare.
LedgerUp
Best for: a B2B SaaS company with complex contract billing that wants one AI agent from contract to cash.
LedgerUp is an AI billing agent for SaaS companies, covering invoicing as well as collections. It charges a flat platform fee starting at $500 a month, independent of how much you bill.
The product is built around contract-to-cash automation. If you need overdue invoices chased rather than your whole billing operation run, you’ll be paying for capability you won’t use.
Lunos
Best for: a team that wants an AI agent handling customer conversations and is happy to pay in line with what it collects.
Lunos is an AI coworker for accounts receivable that follows up with customers and handles their replies. Its pay-as-you-go plan charges 0.3% on collections for the accounts you put it in charge of, and its Growth plan is $15,000 a year for up to $10m in collections.
On pay as you go, the more it collects, the more you pay. If £4m a year runs through it, that’s £12,000 a year, so model it against your own numbers before you commit.
Dunning for annual contracts paid by bank transfer
SaaS and services companies on annual contracts have a particular dunning problem. One invoice can be a whole year’s revenue from a customer, it’s paid by bank transfer rather than card, and there’s nothing to retry. A person in the customer’s finance team has to approve it and send the money.
That changes what a good sequence looks like:
- Start before the due date. A friendly reminder a week before gives the customer time to get the invoice through their approval process.
- Find the right person. The contract was signed by someone in operations or IT. The payment is made by accounts payable. Ask for the AP contact and the PO number early.
- Escalate through the account owner, not just finance. A customer who ignores finance usually answers the person who sold them the contract.
- Log what they say. “It’s in the next payment run” is a promise with a date. A dunning tool that reads replies should pause chasing until that date, then follow up if the money doesn’t arrive.
Worked example: one £24,000 annual invoice
Example UK Ltd invoices Example Customer Ltd £24,000 for a year’s subscription, on 30-day terms, paid by bank transfer. Hannah runs credit control at Example UK Ltd, and Raj is the account owner. In Trove, Hannah sets up a workflow for annual contracts:
| Step | When | Sent by | Paid by this reminder (cumulative share of paid invoices) |
|---|---|---|---|
| 1. Upcoming invoice reminder | 7 days before due | Finance (Hannah) | 49.6% |
| 2. Due today | Due date | Finance (Hannah) | 74.7% |
| 3. First overdue reminder | 7 days overdue | Finance (Hannah) | 85.3% |
| 4. Second overdue reminder, with a statement | 14 days overdue | Finance (Hannah) | 91.1% |
| 5. Escalation | 21 days overdue | Account owner (Raj) | 94.4% |
The right-hand column is from Trove’s data on how many invoice reminders to send: of the invoices that get paid, the share paid by each reminder count, across tens of thousands of invoices chased in Trove. It counts reminders, not days, so treat it as a guide to how many steps to build, not a forecast for this invoice.
If Example Customer Ltd replies after step 2 with “it’s in the run on the 15th”, Trove picks out the date, suggests setting it as the expected payment date in the accounting system, and pauses the sequence. If the money hasn’t landed by then, Trove follows up. Sending the escalation from Raj needs the CRM data on Integrated, so Trove knows who owns the account.

FAQs about dunning software for B2B invoices
What is dunning software?
Dunning software automates the reminders that chase overdue invoices, so follow-up happens consistently without anyone doing it manually. You set a reminder sequence once, and the software sends it on every overdue invoice. Read more about how Trove’s personalised emails work.
What’s the most affordable dunning software for a finance team?
It depends on your revenue, because three of the five tools here price by size or by what they collect. The fixed-price options are Trove, from £65 a month, and LedgerUp, from $500 a month. Chaser starts at £199 a month and rises with revenue, and Lunos charges 0.3% of what it collects on pay as you go.
Does dunning software pricing scale with revenue?
It varies by tool. Chaser bands by revenue and Upflow by ARR, so both step up as you grow. Lunos charges a share of collections. Trove and LedgerUp are fixed.
What’s the difference between dunning, collections and AR software?
Dunning is the automated reminder sequence around the due date. Collections software often means the same thing, though it can stretch to recovering seriously overdue debt. AR software is broader still, adding analytics, cash application and forecasting.
What’s the difference between dunning and credit control?
Dunning is one part of credit control: the reminder sequence. Credit control also covers setting credit terms, checking new customers, handling disputes and promised dates, and deciding when to escalate. Most B2B dunning software, Trove included, covers the chasing and reply handling.
Is there dunning software for invoices paid by bank transfer?
Yes. Invoice dunning tools such as Trove, Chaser, Upflow, LedgerUp and Lunos chase invoices whatever the payment method. They follow up until the payment is reconciled in your accounting system. Card-retry tools like Stripe only help when there’s a card or direct debit to retry.
