Get every receivable
under control

Sunbay is collections automation for European B2B accounts receivable. Sunbay runs overdue invoice chasing, escalation cadences, interest notes, and payment matching across email, SMS, and AI voice calls. Sunbay automates the full collections process from open invoice to cash.
‍
Sunbay connects to European banks (mBank, ING, Pekao, Santander, Barclays), accounting systems and ERPs (Comarch, Symfonia, IFIRMA, SAP), and CRMs (HubSpot, Salesforce, Pipedrive, Attio). Bidirectional sync. Live bank feed reconciliation. Status updates push back to your accounting system automatically.
‍
Most AR collections tools only run email reminders. Sunbay runs multichannel chasing, escalation tiers, interest notes, and a branded payment portal in one platform.
‍
Companies using Sunbay cut DSO by an average of 7 days within 90 days. Tequipy cut payment time from 26 days to 14 days while scaling to €1M per month. Energetyczny Projekt eliminated 80 hours of manual collections work per month and recovered €25,000 in overdue invoices.

Sunbay reduces DSO by automating the collections cadence and closing the gaps where manual chasing leaks. Tequipy cut average payment time from 26 days to 14 days using Sunbay while scaling to €1M per month.
‍
Manual collections fail in four places. Reminders get missed. Escalations fire late. Tone misses the client geography and language. Customers struggle to pay.
‍
Sunbay automates all four. Reminders fire on the day they are due. Escalation tiers move up the cadence automatically (email, then SMS, then AI voice). Interest notes get added per local rules. Customers pay through a branded payment portal.
‍
Sunbay average DSO drops from 28 days to 21 days within 90 days. Tequipy holds zero invoices 90+ days overdue. You reduce DSO by automating the chase, not by sending more reminders.

Sunbay integrates with European accounting systems, banks, and CRMs. The collections cadence runs on top of your existing stack.
Banks include mBank, ING, Pekao, Santander, and Barclays. ERPs include Comarch, Symfonia, IFIRMA, and SAP. CRMs include HubSpot, Salesforce, Pipedrive, and Attio.
‍
Sync is bidirectional. Sunbay reads your open invoices and customer data, runs the collections cadence, and pushes status back (chased, promised, paid) to your accounting system automatically. Bank feeds run live. Sunbay marks the invoice paid when the payment lands.
‍
Sunbay also connects via API for custom and regional accounting, banking, and CRM systems. No data migration.

Sunbay automates the full collections process for European B2B accounts receivable.
‍
Sunbay chases overdue accounts on the cadence you set across email, SMS, and AI voice calls. Escalation steps are configurable from gentle reminder to firm reminder to final demand. Every new client or invoice routes into the right collections flow automatically by geography, language, client type, and tone. Interest notes and final demands get added per local rules. Customers pay through a branded payment portal.
‍
One live dashboard shows every receivable down to the individual invoice. Paid, pending, overdue. Risk flags fire before invoices cost you. Workflows run on autopilot once rules are set. You can also trigger any collections step manually.
‍
Sunbay connects to your accounting system, bank feed, and CRM via API. No data migration. No new system of record.
