AI agents can run most of the routine B2B collections work: sending reminders on schedule, sharing invoice copies, logging promises to pay and flagging disputes. Keep people on disputes, payment plans and your most important customers. Segment accounts so the cadence fits the relationship, and measure days past due rather than emails sent.
Collections is where automation can go wrong quickly. A blunt reminder to a customer who is waiting on a credit note from you damages the relationship and does not speed up payment. The fix is to resolve disputes first and set the tone by segment.
Step 1: Segment your accounts
Group customers by value and behavior:
- Key accounts: high value or strategic. People own the relationship.
- Reliable payers: usually on time. A light-touch reminder is enough.
- Habitual late payers: need a firmer, earlier cadence.
- New accounts: watch closely for the first few invoices.
Step 2: Set a contact cadence by segment
Write the schedule for each segment: a friendly reminder a few days before the due date, a statement on the due date, then follow-ups at set intervals, and an escalation point where a person takes over. Agree the wording for each message in advance.
Step 3: Fix disputes before chasing payment
When a customer replies with a problem, such as a pricing error, a missing proof of delivery or a short shipment, pause reminders on that invoice and route it to the person who can fix it. Resolve the dispute, send the corrected document and restart the cadence.
This is where many overdue days come from. Invoices are late because something is wrong with them.
Step 4: Keep people on the accounts that matter
Key accounts, payment plans and anything that could end the relationship stay with your credit controllers. The agent prepares the account summary, the aged items and the history of contact so the conversation starts with the facts.
In the US, business-to-business collections are generally outside consumer debt collection laws, but check the rules that apply in each state and country you collect in, and keep your own standards for tone either way.
Step 5: Measure days past due, not calls made
Track average days past due, overdue balance by age band and the number of open disputes and their age. Report them monthly next to DSO.
Where AI agents fit
In our finance operations service, agents run the cadence, log every contact and promise to pay, and route disputes with the evidence attached. People handle key accounts and escalations. Part of the fee is a share of the verified reduction in days past due, measured against a baseline from your own ledger.
