Monitor unpaid invoices in NocoDB, retrieve client data, categorize escalation levels, and automatically dispatch multi-channel reminders.
The AI agent fetches unpaid invoices from NocoDB with linked client data, classifies each invoice by escalation level (reminder, warning, legal notice). It generates professional HTML content and sends reminders via Gmail, writes letters via PostGrid when needed, and posts Slack messages for internal tracking. It logs status changes and preserves a complete audit trail across all invoices.
Automates end-to-end overdue communications and status updates.
Retrieve invoices and client data from NocoDB
Filter out paid invoices and assign escalation level
Generate HTML reminders for each escalation level
Send emails via Gmail
Dispatch physical letters via PostGrid
Notify internal team via Slack
Before you adopt this AI agent, overdue reminders were manual, inconsistent, and the risk of late payments was high. After deployment, reminders are timely and multi-channel, escalation stages are preserved, and you gain visibility into every invoice's status.
A simple 3-step flow anyone can follow.
Define escalation thresholds, enable channels, and input company details; connect NocoDB and credentials.
Fetch unpaid invoices and related client records from NocoDB, processing in batches.
Apply filters to categorize invoices by escalation level, generate communications, and send via Gmail, PostGrid, and Slack.
One realistic scenario.
Scenario: A software agency with 60 invoices. On a daily run at 7:00 AM, the agent identifies 5 invoices due in 4 days and sends friendly reminders via Gmail; it flags 3 invoices exactly 7 days overdue to send formal warnings via Gmail and Slack; it flags 1 invoice exactly 10 days overdue to send a legal notice via PostGrid and Slack.
Roles that gain precise, reliable payment follow-up.
Automate reminders and improve consistency in collections.
Gain centralized visibility into aging and escalation status.
Enforce payment terms across multiple clients.
Maintain professional client communications.
Track payment behavior and risk signals.
Simplify multi-channel delivery and address formatting.
Tools connected to enable end-to-end reminders.

Post internal notifications and tracking updates.
Practical scenarios that benefit from automation.
Common concerns about using the AI agent for reminders.
The AI agent is a data-driven automation that monitors invoices in NocoDB, applies escalation rules based on due dates, and automatically sends reminders through Gmail, PostGrid, and Slack. It generates professional HTML and letters aligned with the escalation stage (friendly, formal, or legal) and processes invoices in batches to prevent duplication. It maintains a detailed activity log for auditability and compliance. It can be customized to match your exact payment terms and communication style.
The primary data source is NocoDB, where invoices and client details are stored. Gmail and PostGrid are optional channels for electronic and physical communications, respectively, and Slack is used for internal notification. The AI agent assumes a relational model where each invoice links to a client, enabling personalized messaging. You can configure authentication and connection details for each integration to ensure secure access. Data schemas and fields should reflect your invoicing workflow to ensure accuracy.
Yes. Escalation timing is configurable in the Config settings, including when to send reminders before due date, when to issue warnings after due dates, and when to trigger legal notices. Thresholds can be adjusted to fit your payment terms and cash flow needs. The agent validates logical sequence to avoid mis-timed actions, and it preserves escalation order across all invoices. Changes apply to future reminders without disrupting already sent communications.
The AI agent relies on NocoDB currency fields for amount data, which can be configured for PLN, EUR, USD, GBP, or other currencies. You can switch the currency at the table level without modifying the reminder logic. All communications display the currency consistently across emails, letters, and invoices. Currency changes apply to the current and future invoices in the base, ensuring accurate billing.
If a delivery attempt fails, the agent logs the failure and retries according to your configured policy. It isolates errors to individual invoices so a single failure does not block others. The audit trail records retries, timestamps, and channel used. If a channel remains unavailable, it can fall back to alternate channels within the same escalation level to maximize delivery success.
The AI agent supports email via Gmail, physical letters via PostGrid, and internal notifications via Slack. Each channel can be toggled on or off and can carry channel-specific content (HTML emails, printed letters, and Slack blocks). Channel behavior adapts to escalation level, ensuring appropriate tone and urgency. You can test channels independently to validate delivery without altering escalation rules.
Security is treated as a priority: access is controlled via OAuth2 and API tokens, data in transit is protected, and credentials are scoped to the respective integrations. The AI agent logs actions with timestamps to support traceability and auditing. Data exposure is minimized by using least-privilege access and separation of duties across integrations. Regular reviews of permissions and credential rotation are recommended as part of governance.
