Superclaim and Fortnox: AI Agents That Collect Invoices, Handle Disputes, and Eliminate Manual Follow-Up

Fortnox knows exactly which invoices are unpaid. It knows which customers are late. It knows the amounts, the due dates, the payment history. All the data is there — in real time, structured, accurate.

Yet finance teams across Sweden are chasing payments manually. Not because the data is missing, but because Fortnox — like all accounting systems — isn't built to act on it. Fortnox keeps track of the numbers. But it doesn't collect the money.

Superclaim connects AI agents directly to Fortnox. The agents read the same data as the finance team — invoice status, customer history, payment flows — and do what nobody has time to do manually: follow up on every overdue invoice, tailor every reminder, handle every invoice dispute, and continue until the invoice is paid.

Fortnox plus Superclaim: the accounting system that keeps order, and the AI agents that collect the payments.

Why Fortnox data is the key to better collections

What makes Superclaim's Fortnox integration powerful isn't just that data syncs — it's which data syncs and how the AI agents use it.

From Fortnox, Superclaim retrieves in real time:

• Invoice status — which invoices are outstanding, overdue, and paid
• Payment history — the customer's patterns over time: do they always pay late? Do they typically pay after the second reminder? Have they made partial payments before?
• Customer data — organization number, contact details, invoicing method
• Amounts and terms — exact sums, due dates, any late fees

This data enables Superclaim's AI agents to make intelligent decisions. A customer who, according to Fortnox history, always pays within 45 days is treated differently than a customer with three overdue invoices and no payment pattern at all. Without Fortnox data, the agents would be blind. With it, they see the full picture.

The sync is continuous. When a payment is registered in Fortnox, Superclaim automatically stops follow-up for that invoice. When a new invoice becomes overdue, it starts. The finance team doesn't need to do anything — Fortnox and Superclaim stay in sync in the background.

How Superclaim's AI agents work with Fortnox data

Superclaim has two AI agents working against Fortnox data, each with a clear mission. Both are controlled by the finance team through Mission Control.

Claims Agent: proactive collection powered by Fortnox data

Claims Agent monitors the Fortnox receivables ledger continuously. The moment an invoice passes its due date, the agent already has all the information it needs: amount, invoice number, customer history, past payment behavior.

Based on that data, Claims Agent decides what the follow-up should look like:

Customer with good history, one-time miss: Fortnox shows the customer paid 47 out of 48 invoices on time in the past year. Claims Agent sends a friendly reminder — collegial tone, no threats, just the invoice number and amount. Often, that's enough.

Systematic late payer: Fortnox shows a pattern — the customer consistently pays 20–30 days past due. Claims Agent adjusts the strategy: reminder on day 3 instead of day 7, clearer tone, shorter intervals between follow-ups.

Large outstanding receivable, no response: Fortnox shows the invoice has passed 30 days without payment or contact. Claims Agent escalates — new channel, sharper tone, potentially SMS via Kivra in addition to email.

Every decision is based on real-time data from Fortnox. Not on a static rule sequence that looks the same for everyone.

Inbox Agent: resolving what blocks payment in Fortnox

Half of all late payments aren't due to unwillingness. They're due to something blocking payment: the customer has a question about the invoice, needs a copy in a different format, disputes an amount, or never received the invoice at all.

Inbox Agent monitors the inbox and links incoming emails to open invoices in Fortnox. When a customer writes "Can you resend invoice 10432?", Inbox Agent retrieves the invoice from Fortnox, verifies status and amount, and responds — often within minutes.

Cases that Inbox Agent resolves automatically using Fortnox data:

• Invoice copies — retrieves invoice information directly from Fortnox and sends
• Payment confirmations — checks payment status in Fortnox and confirms
• Balance statements — compiles outstanding invoices from the Fortnox receivables ledger
• Payment plans — suggests arrangements based on the customer's total outstanding in Fortnox

Complex cases — disputes, credit notes, escalations — are compiled by Inbox Agent with all relevant Fortnox data and presented to the finance team in Mission Control, including a suggested response. The team reviews, edits if needed, and approves. The customer gets a response the same day.

Mission Control: full control over what AI agents do with your Fortnox data

Mission Control is the dashboard where the finance team steers everything. Every action that Claims Agent or Inbox Agent proposes — every reminder, every escalation, every customer response — is displayed here before it's executed.

The team sees: - Which invoice from Fortnox it concerns - Which customer, with full history - What the agent proposes to send - Why (based on which Fortnox data)

One click to approve. One click to edit. One click to reject.

No AI action leaves the system without human approval. This is a fundamental design principle: Fortnox data is sensitive business data. Customer relationships are valuable. Superclaim lets AI do the heavy lifting — but the finance team makes the decisions.

What happens in the first 30 days after an invoice is overdue

There's a window in every unpaid invoice where follow-up has maximum impact: the first 30 days after the due date.

An invoice that is 30 days overdue has significantly higher payment probability than one that has passed 60 days. At 90 days, the probability has halved. At 180 days, the invoice is statistically a write-off.

In most companies, reality looks like this: Fortnox shows an overdue invoice on day 1. The finance team sees it — maybe. A reminder is sent on day 7. Then month-end closing takes over. The next time someone looks at the receivables ledger, it's day 35. The critical window has already started closing.

With Superclaim connected to Fortnox, Claims Agent works within that window from day 1. Every overdue invoice in Fortnox gets immediate, systematic follow-up. No invoice ages in silence. No case falls through the cracks.

Why Fortnox's reminder function isn't enough

Fortnox has a built-in reminder function. It sends a standard reminder — same template, same text, same channel — to all overdue invoices. It's better than nothing. But it's far from sufficient.

Fortnox reminders lack:

• Per-customer adaptation — same tone to loyal partners and chronic late payers
• Intelligent escalation — if the reminder is ignored, nothing happens automatically
• Response handling — if the customer replies with a question, someone must read and respond manually
• Channel variation — email only, no option for SMS or other channels
• Context from ongoing dialogues — no connection to what's already been said in email threads

Superclaim doesn't replace Fortnox. It complements Fortnox — takes the accounting data and transforms it into active, intelligent collection.

Traditional dunning vs. AI agents with Fortnox integration

Dunning software automates reminder sequences: email 1 on day 7, email 2 on day 14, email 3 on day 30. Same flow for everyone. It's marginally better than manual work, but it doesn't solve the core problem: lack of context.

Superclaim with Fortnox works differently:

| | Traditional dunning | Superclaim + Fortnox | |---|---|---| | Reminders | Static templates | AI-tailored per customer based on Fortnox data | | Escalation | Time-based (day 7, 14, 30) | Context-based (what has happened in the case?) | | Invoice disputes | Manual handling | Inbox Agent resolves automatically with Fortnox data | | Channels | Email only | Email, SMS, Kivra | | Control | Fully automated or fully manual | Mission Control — AI proposes, humans decide | | Data source | Imported CSV | Real-time sync with Fortnox |

Which companies benefit most from Superclaim + Fortnox

Superclaim is built for Fortnox users who recognize this:

• You have dozens or hundreds of outstanding B2B invoices and no dedicated person handling collections
• Your finance team handles collection alongside bookkeeping, reporting, and month-end closing
• You send reminders through Fortnox but follow-up after that is manual and inconsistent
• You've watched invoices age and cash flow suffer, but don't want to send customers to debt collection
• You want control — not a black-box system that sends things without your knowledge

The Fortnox integration means zero friction to get started. Superclaim works with the data that already exists. No exports, no manual syncing, no new system to learn.
