Summary
SAP Business One is a strong ledger with a capable Dunning Wizard of up to 10 levels. A person still starts each run, and promises and disputes need partner add-ons. A credit control tool adds reading replies, SMS and post, and chasing that runs on its own. Pick the tool for the job your team finds hardest.
- Paidnice: Best for teams that want the whole chase handled. Paidnice reads each reply with AI and drafts the answer for a person to approve, sends SMS and posted letters, and posts fees to SAP Business One as invoices. Credit checks through your Creditsafe API connection, on the Custom plan.
- Kolleno: Best for groups over £100M turnover whose hardest job is matching payments to invoices. Its strength is cash application, with credit scoring built in. Price on request.
- ezyCollect: Best for AU and NZ mid-market teams that want credit checks on illion data and a payment portal in one platform. Price on request.
- SAP Business One on its own: The Dunning Wizard prints or emails letters at up to 10 levels. It emails the one address on each business partner and does not read the reply.
Paidnice connects to your ERP on the Custom plan. Book a demo on your own data, and a specialist sets up the connection.
Credit control software for SAP Business One adds what the native Dunning Wizard and partner add-ons leave behind: reading the reply, holding the next letter for a promised date, SMS and posted letters, and an owner for each account. Book a demo to see Paidnice on your own SAP Business One ledger.
What does SAP Business One include for credit control by default?
SAP Business One includes a Dunning Wizard with up to 10 dunning levels, a fee and interest per level, a Block Dunning Letters flag, and print or email delivery. SAP's dunning documents name no add-on for these.

Sources: SAP's how-to guide for the dunning process (release 8.8), SAP's dunning terms reference (10.0), and a SAP Community answer that says the wizard emails the address on the business partner record.
The dunning terms set the grouping method, maximum level, fee, minimum balance, interest rate and the G/L accounts for fees and interest. When the term's auto-post option is on, the wizard lists recommended service invoices for fees and interest, and you accept or remove them.
Email from the wizard arrived in release 9.1 PL6, per an SAP partner's write-up.
In the Web Client, Feature Package 2608 adds a Reminder Assistant that builds and dispatches reminder letters and can post fees and interest (optional), and dunning runs can be scheduled in the background, per a partner's feature summary that gives no year.
What needs an add-on in SAP Business One?
SAP's dunning documents describe no promise to pay, dispute status, collector queue or customer portal. Partners sell add-ons for some of these.
Collections add-on, built to order
Adds promise to pay, dispute tracking and a collector queue on top of the wizard. This vendor builds it to order, so scope and price are set per customer.
Print and delivery add-on
Controls how documents print and email. In an SAP Community thread, a user reports the wizard's email option stayed hidden until the add-on's dunning setting was changed.
Scheduled email runs, partner-scripted
In an SAP Community thread, a partner described a B1iF scenario on a timer that emailed dunning letters every half hour. It is an older workaround; the Web Client now offers background runs, per a partner.
What does the Dunning Wizard still miss?
The Dunning Wizard builds and sends the letters; it does not read the reply, record a promised date, route to a second contact, assign an owner or send SMS.
- Read the reply. The Dunning History Report lists what was sent. A person decides whether the reply is a dispute, a query or a promise to pay.
- Note the promised date somewhere else. The dunning terms hold levels, fees, interest and G/L accounts; a promised date is not among them. A promise nobody records never reaches the cash forecast.
- Tick Block Dunning Letters on the disputed invoice. It is the per-invoice control in SAP's guide, and someone has to untick it later, because the wizard never knows the dispute ended.
- Re-send by hand when AP uses a different address. The wizard's run holds one email field per business partner, so a letter sent to the buyer waits in the wrong inbox.
- Decide who owns the account next. SAP's guide describes no owner field, and the history report shows what was sent. The account goes quiet with nobody named.
- Start every desktop run. SAP's 8.8 guide has no schedule step; since Feature Package 2608 the Web Client can schedule runs in the background, per a partner's summary.
Replies land in a mailbox outside SAP Business One, so the dunning history is in one place and the customer conversation in another. Users also report a "Failed to create e-mail for business partner" error, covered by SAP Note 2671577 in a community thread.
Where Paidnice fits: if you want to...
Paidnice connects to SAP Business One on the Custom plan and takes over at the point where the wizard hands the work back to a person: the reply, the promised date, the second contact and the owner.
| If you want to... |  SAP Business One + add-on |  Paidnice |
|---|---|---|
| Read replies and log a promised date | Add-onPromise to pay, 1 vendor | YesPauses until that date |
| Post late fees as invoices | IncludedIf auto-post is on | YesDraft or Approved |
| Send SMS and posted letters | Not documentedDocs name print or email | YesEmail, SMS, letters |

| Run without a person starting it | PartialWeb Client, per partner | YesRuns on its own |
Paidnice is good for you if you want to:
- Stop chasing the moment a payment posts. Invoices, payments and credit notes sync instantly, so a payment posted in SAP Business One stops chasing straight away.
- Have the reply read and the run held. Paidnice reads the reply, drafts the response, logs the expected payment date and pauses chasing until that date. A person approves every send.
- Post fees and interest from a policy. Fees and interest land in SAP Business One as invoices, Draft or Approved. UK base-rate interest (3.75% since 17 June 2026) is indexed automatically. The charge sits in the customer's payables as leverage.
- Reach the person who pays. Contact groups route email and SMS and posted letters to the accounts payable contact, on their own schedule.
- Name an owner after the last level. Escalation workflows open a task for the owner at the day count or balance you set. A payment portal on every reminder takes payment through Stripe or Pinch.
Paidnice customers cut their average wait for payment in half, within 30 days. SAP Business One runs on the Custom plan. An implementation specialist and a dedicated account manager set it up with you.

How to choose credit control software for SAP Business One
Ask each vendor six questions. Each one maps to a control the Dunning Wizard already has or lacks.
- Does a payment posted in SAP Business One stop the next letter? Two-way sync is the essential; a letter sent after the payment landed costs the relationship.
- Can it send to an accounts payable contact that is not the business partner email? The wizard's run holds one email field per business partner.
- Does a reply with a date pause the sequence? The wizard runs on dunning levels and dates.
- What happens after the last dunning level? The terms stop at their maximum level with no task, owner or posted final notice.
- Do fees and interest post as invoices in SAP Business One? With auto-post on, the wizard recommends service invoices for fees; keep that in the replacement.
- Does it run without a person starting it? The desktop wizard needs a person for every run; since Feature Package 2608 the Web Client can schedule background runs, per a partner's summary.
Nice to have: a customer portal with a payment link, consolidated parent and child statements, and a credit check on new customers through Creditsafe.

SAP Business One credit control: common questions
Short answers on dunning runs, fees, SMS and post, disputed invoices and the Paidnice connection to SAP Business One.
Does SAP Business One send dunning letters automatically?
Partly. The Dunning Wizard checks every overdue document and builds a letter per level once a person runs it. In the desktop client a person starts every run; since Feature Package 2608 the Web Client can schedule runs in the background, per a partner's summary. Nothing in the wizard reads the reply.
Can SAP Business One charge late fees and interest?
Yes. Each of the up to 10 dunning levels carries a fixed fee per letter, and the dunning terms can add annual interest above a minimum balance. With auto-post on, the wizard lists both as service invoices to accept or remove. Paidnice raises the fee from a policy as an invoice in SAP Business One, Draft or Approved.
Can SAP Business One send reminders by SMS or post?
The wizard prints letters or emails them, since release 9.1 PL6, to the email field on the business partner record. SMS does not appear in SAP's dunning terms reference or how-to guide, and printed letters are posted by your team. Paidnice adds SMS and printed, posted letters on the same sync.
What happens to a disputed invoice in a dunning run?
You tick Block Dunning Letters on the invoice, or on the business partner to skip every invoice for that customer. The wizard then leaves it out of the recommendation report. Someone has to untick the flag once the dispute ends, because the wizard has no dispute status; SAP's how-to guide, written for release 8.8, gives both steps.
Does Paidnice connect to SAP Business One?
Yes, on the Custom plan. Invoices, payments and credit notes sync instantly, fees and interest post back as invoices, and reminders, SMS, posted letters, statements and escalations run on top of your dunning terms. Customers cut overdue invoices by 70% in their first 30 days.
