How to Build an Accounts Receivable App with Bubble

Building an accounts receivable app with Bubble gives finance teams a system that chases payments automatically instead of manually. Unpaid invoices sitting in email threads are a revenue problem, not just an admin inconvenience.

Bubble handles invoice generation, automated reminder scheduling, partial payment tracking, and Stripe-powered online collection without custom backend code. The result is a real-time view of outstanding money with automated follow-up built in.

Key Takeaways

• Customer and invoice data types are inseparable: Every AR workflow depends on a clean relational link between Client, Invoice, and Payment records.
• Automated reminders run on scheduled workflows: Bubble's backend scheduler triggers payment reminder emails at configurable intervals before and after due dates.
• Partial payments need their own data type: Storing each payment separately against an invoice rather than a single paid/unpaid flag supports partial payment tracking and reconciliation.
• Aging reports are built natively: Filtered repeating groups sorted by due date give finance teams overdue invoice views without third-party plugins.
• Stripe handles payment collection: Clients can pay invoices via a Stripe-powered payment link or embedded checkout generated directly from the invoice record.

What Is an Accounts Receivable App — and Why Build It with Bubble?

An accounts receivable app generates and sends invoices to customers, tracks payment status, automates follow-up reminders, and reports on outstanding balances. It does all of this in one system.

Core user roles are billing staff, finance manager, account manager with client-facing invoice views, and read-only reporting access for leadership.

• Custom invoice workflows: Accounting software AR modules lock you into their templates and reminder schedules; a Bubble build gives you complete control over invoice format and follow-up timing.
• Client self-service payments: Generate Stripe payment links embedded directly in invoice emails so clients can pay without calling or sending a bank transfer.
• Partial payment tracking: Most accounting tools treat invoices as paid or unpaid; a Bubble app records every partial payment separately and calculates the real outstanding balance.
• Milestone billing support: For project-based businesses, Bubble AR apps handle milestone-linked invoicing that standard AR modules cannot accommodate.

There is a wide range of financial apps built with Bubble already in production. AR and invoicing tools are among the most common. Teams with milestone billing or multi-currency needs choose to build the AR app in Bubble rather than work around the constraints of standard accounting software.

What Features Should an Accounts Receivable App Include?

A complete AR system covers the full billing cycle from client setup through overdue collection. Scoping every feature before building prevents database rework mid-project.

The list below defines the minimum scope for a system that meaningfully replaces email-based invoice management.

• Client management: A CRM-style Client data type with contact details, payment terms, credit limit, and a full invoice history view per client.
• Invoice creation: A line-item invoice builder with client lookup, due date, tax calculation, discount field, and PDF generation on send.
• Payment recording: Log each payment against an invoice - amount, date, method, reference - to support partial payment tracking and reconciliation.
• Automated payment reminders: Scheduled workflows send reminder emails at configurable intervals: 7 days before due, on the due date, 7 days overdue, and 30 days overdue.
• Aging report: Outstanding invoices grouped by 0–30, 31–60, 61–90, and 90+ days overdue - built from a filtered, sorted repeating group.
• Stripe payment link: Generate a unique payment URL per invoice so clients can pay online via card without any friction.
• Credit notes and adjustments: Issue credit notes against paid or outstanding invoices, stored as CreditNote records linked to the original invoice.
• Finance dashboard: Total outstanding, total collected this month and quarter, and overdue amounts broken down by client.

The automated reminder sequence transforms a basic invoice tracker into a real AR system. It does the follow-up work that billing staff otherwise do manually every day.

How Do You Structure the Database for an Accounts Receivable App in Bubble?

The data model for an AR app is more relational than most Bubble projects. Getting it right before building any workflows saves significant rework.

Your core data types are Client, Invoice, InvoiceLine, Payment, CreditNote, and ReminderLog.

• Client fields: company_name, contact_name, email, billing_address, payment_terms option set (net14, net30, net60), credit_limit number, currency text, and account_manager user link.
• Invoice fields: Client link, invoice_number, issue_date, due_date, subtotal, tax_rate, tax_amount, total_amount, amount_paid (calculated), outstanding_balance (calculated), and status option set (draft, sent, partially_paid, paid, overdue, cancelled).
• InvoiceLine fields: Invoice link, description, quantity, unit_price, and line_total. Stored separately to support line-item PDF generation.
• Payment fields: Invoice link, payment_date, amount, payment_method option set, reference, and recorded_by user for audit trail.
• CreditNote fields: original_invoice link, amount, reason, issue_date, and applied_date for reconciliation purposes.
• ReminderLog fields: Invoice link, sent_date, reminder_type option set (pre-due, due-date, overdue-7, overdue-30), and email_sent_to for tracking outreach history.

The calculated fields pattern is critical: amount_paid is a sum of all linked Payment records; outstanding_balance is total_amount minus amount_paid. Never store these as static fields. Keep them as dynamic expressions so they always reflect the current state.

How Do You Build the Core Workflows for an Accounts Receivable App in Bubble?

The most valuable workflows in an AR system are the ones that run automatically. Reminder emails, overdue status updates, and payment confirmation all fall into this category. Build these before the UI.

Each workflow covers a specific stage of the billing cycle and feeds into the next.

• Invoice send workflow: Finance user clicks Send; workflow generates a PDF via PDF Conjurer, updates Invoice status to "sent," and sends an email via SendGrid with the PDF attached and a Stripe payment link URL.
• Payment recording workflow: User logs a payment; workflow creates a Payment record, recalculates amount_paid by summing all Payments linked to the invoice, updates outstanding_balance, and changes Invoice status to "partially_paid" or "paid" based on balance.
• Automated reminder scheduling: When Invoice status changes to "sent," a series of backend workflows are queued for each reminder date; each scheduled workflow checks whether the invoice is still unpaid before sending the email.
• Overdue status update: A recurring daily scheduled workflow searches invoices where due_date is in the past and status is "sent" or "partially_paid" - updates status to "overdue" automatically.
• Stripe payment link generation: Workflow calls Stripe's API via API Connector to create a Payment Link for the invoice's total_amount and stores the returned URL on the Invoice record.

Applying Bubble's data privacy rules correctly ensures that client invoice data is only visible to authorised users. Open search queries must never expose invoice data to unauthorised roles.

What Plugins and Integrations Does an Accounts Receivable App Need?

The plugin stack for an AR app handles payment collection, email delivery, PDF generation, and data export. Each tool has a specific, non-overlapping role.

Choosing the right plugin for each function keeps the app maintainable and avoids redundant tooling.

• Stripe plugin: Generates payment links, processes card payments, and handles webhook events for automatic payment confirmation on the Invoice record.
• SendGrid plugin: Sends invoice emails with PDF attachments, automated reminder sequences, and payment confirmation receipts.
• PDF Conjurer or Documint: Generates professional PDF invoices from Invoice and InvoiceLine records - essential for sending branded, formatted invoice documents to clients.
• Air CSV or CSV Creator plugin: Exports aging reports and payment history to CSV for accountant import or ERP reconciliation.
• API Connector: Handles Stripe webhook events - charge.succeeded and payment_intent.payment_failed - to automatically update Invoice status from payment events without manual intervention.
• Bubble's Scheduler (built-in): Runs recurring daily workflows for overdue status updates and the full automated reminder sequence.
• Xero or QuickBooks integration via API Connector (optional): Syncs paid invoices back to the accounting ledger if Bubble is used alongside an existing accounting platform.

The Stripe webhook integration via API Connector is the most technically involved plugin setup. Getting this right means Invoice status updates automatically when a client pays, without any manual reconciliation by your billing team.

How Long Does It Take and What Does It Cost to Build an Accounts Receivable App with Bubble?

Build timelines depend on whether you need a client-facing portal, multi-currency support, or ERP sync. Plan the scope before estimating.

Checking the right Bubble pricing plan before you start prevents hitting workflow run limits or missing features you assumed were available on the base plan.

• Solo builder timeline: 5–8 weeks for a full AR app with invoicing, partial payments, automated reminders, and a basic aging report.
• Agency-built timeline: 3–5 weeks with a Bubble developer experienced in financial workflow apps.
• Bubble plan: Growth plan is recommended for AR apps requiring scheduled workflows, custom domains, and multiple user roles.
• Third-party costs: Stripe payment link fees at standard transaction rates; SendGrid free tier covers up to 100 emails per day; PDF generation plugins at $10–$29/month.
• Total monthly running cost: $50–$120/month depending on Bubble plan and email and PDF volume.
• Build complexity drivers: Client-facing self-service portal, multi-currency support, ERP sync, and automated dunning sequences beyond standard reminders are the four main complexity and cost drivers.

The automated reminder sequence and Stripe webhook integration together account for the majority of build time in a well-scoped AR project. Plan accordingly.

Conclusion

Bubble gives AR teams a complete invoicing and payment tracking system with automated reminders, partial payment support, and Stripe-powered online collection built around their specific billing cycle.

Build the Client and Invoice data types first, then wire the payment recording and reminder scheduling workflows. Validate the data model end-to-end before adding Stripe integration or ERP sync.
