Invoices in your TMS. Reminders and agreements in Sunbay.

You don't have to build an overdue list every week or check each invoice one by one. Sunbay shows who hasn't paid, sends reminders and keeps the history of every contact with the customer.

Area
Without Sunbay
With Sunbay
Invoices
Every week you combine data from your TMS and accounting to see who hasn't paid.
Sunbay pulls invoices from the connected system. A payment booked in your ERP closes the case and cancels the remaining reminders.
Reminders
Someone has to check the due date, write the message and remember the next follow-up.
You decide after how many days to send an email or SMS. Sunbay sends them automatically in the language you choose.
Agreements
Only the person who spoke to the customer knows when they promised to pay.
You save the promised payment date with the invoice, along with the person who will follow it up. The whole team can see it.
Interest notes and demand letters
You prepare the interest note and the demand letter separately, then attach them to an email.
Sunbay prepares the interest note and the demand letter and sends them on the day you set.
Reports
When management asks about overdue invoices, you gather the data and build a summary in Excel.
You see how much money customers owe and for how long. You can get this report by email every week.
Team
Every new invoice means another due date to check and another message to send.
Sunbay sends reminders and checks payments. Your team sorts out disputed amounts and agrees payment dates with customers.
Exceptions
An undelivered email, a missing address, a disputed invoice and a customer's promise to pay end up in someone's inbox or memory.
Sunbay turns them into tasks with a due date and an owner. You take a disputed invoice out of the process, and reminders to other customers keep going out. You save the agreement with the invoice, and Sunbay keeps track of the date.
Contact history
Calls, emails, notes and decisions are scattered across inboxes, Excel and people's memory. When someone leaves or goes on holiday, the knowledge goes with them.
Each customer has one record that shows sent messages, delivery statuses, team comments and tasks. A new person can see right away what happened and where the case stands.

You decide once when to remind customers to pay. Sunbay keeps track of every invoice.

A path is a plan for contacting the customer, that is, when to send an email, SMS or demand letter. Sunbay follows the path for each customer until the payment is booked in your ERP or you pause the reminders.

01 / INVOICES

Sunbay pulls in invoices.

Upload a list of invoices from a CSV file or connect Sunbay to your TMS or accounting system. You choose which overdue invoices get reminders.

02 / REMINDERS

The customer gets reminders.

Sunbay sends emails and SMS messages on the days you set. You choose the content, the language and when to send a demand letter or have someone on your team call.

03 / TEAM SUPPORT

Your team handles specific cases.

When a customer asks for more time, you save the new payment date and pause the reminders. If an email doesn't get through, Sunbay creates a task to check the customer's address.

04 / ANALYTICS

Receivables analytics

Aging, DSO, path performance and a cash inflow forecast.

For every invoice you can check the messages sent, the customer's replies and what your team agreed. During onboarding we'll work out how to connect Sunbay to your TMS, your accounting system and KSeF, the Polish e-invoicing system.

FAQ

Questions about receivables in transport and logistics

Answers for finance teams at carriers and freight forwarders.

Is Sunbay a debt collection agency?

No. Sunbay is an accounts receivable platform. Reminders, interest notes and payment demands go out in your company's name, and you decide on every next step. If a customer still doesn't pay after a demand, you hand the case to a law firm or the KRD debtor register with the invoice, demands and contact history (in the Pro plan). Read how a debt collection agency compares with software.

How do I connect Sunbay to my TMS?

A CSV file with invoices for one group of customers is enough to start. During implementation we agree how to connect Sunbay to your TMS, accounting system and KSeF, Poland's e-invoicing system. A payment booked in your ERP closes the case and stops further reminders. You can check ready connections on the integrations page.

When does Sunbay send reminders?

Whenever you set them in the reminder path. The first email can go out a few days before the payment due date, and further emails and text messages on chosen days after it. Customers abroad get messages in the language you choose, for example German. With hundreds of invoices you set one path for a whole customer group, as shown on the collections page.

What if a customer disputes a freight invoice?

You take the disputed invoice out of the process, and the other invoices keep getting reminders. Sunbay creates a task with a deadline and an owner, so a dispute over damaged cargo or a missing document doesn't get lost in an inbox. You note what you agreed with the customer on the invoice, and the whole team can see it.

Can I charge interest and compensation for late payment?

Yes, if the customer is a business or a public body. Under Polish law, from the day after the due date you can charge statutory interest for late payment in commercial transactions and a fixed compensation for recovery costs of €40, €70 or €100, depending on the invoice amount. Sunbay prepares the interest note and the payment demand and sends them on the day you choose.

How long do I have to claim payment for a transport job?

Usually one year. That is the limitation period for claims under a contract of carriage, both for domestic carriage in Poland (Article 77 of the Transport Law) and for international road carriage (Article 32 of the CMR Convention). When the year starts counting depends on the type of carriage and claim. In Sunbay you see how many days have passed since each invoice was due, and you decide when to send a payment demand or pass the case to a law firm.

How much does Sunbay cost?

You pay a monthly subscription based on the number of invoices, with no commission on recovered amounts. Plans start at €290 a month, and implementation is a one-time fee of €1,000. See the pricing page for details.
