AR Chaser for n8n | Invoice Follow-up Automation
You automate everything for clients — except getting paid yourself. Industry surveys show 92% of accounting firms invested in new technology last year, most of it aimed at doing more work, not at collecting the invoices that fund it. AR Chaser follows up the money your practice is owed: a gentle pre-due nudge, then staged reminders after the due date, an escalation for anything that drifts past 30 days, and a weekly aged-receivables summary — so you stop letting your own invoices age quietly.It's two n8n workflows on one Google Sheet, using wording that stays professional and relationship-safe even at the final notice.What's inside 2 ready-to-import n8n workflows: Payment Reminder Engine — checks your invoice ledger daily and sends the right stage for each invoice: pre-due reminder → first overdue → second overdue → final notice. Each stage sends once (it records where it's up to), so running twice a day never double-sends, and a newly-overdue invoice goes straight to the correct stage. Escalation & Weekly AR Summary — surfaces anything over 30 days for a human, and emails you a weekly total-outstanding + aging breakdown, grouped correctly by currency. A Google Sheets template spec — Clients and Invoices tabs with headers and samples. The Clients tab matches the other Flowcask accounting products, so they share one sheet. Editable, staged email templates — four tones from pre-due to final notice, professionally written to collect without threatening. Multi-currency handling — set a default symbol/code and override per invoice; totals are summed in whole cents to avoid rounding drift. A step-by-step setup guide — live in about 30–45 minutes, no coding. An optional AI personalization mode — off by default; add your own OpenAI key to reword each reminder while keeping the amounts, dates, payment details, and signature exact. Your licence file. How it works Import the two workflow files into your own n8n. Copy the sheet template and add your open invoices to the Invoices tab. Connect Google once (Sheets, Gmail) — one credential, reused.
