Email + SMS

AI writes every message

Claude AI generates a unique email for each client — referencing the specific work, amount, and history. On Professional and Business plans, SMS reminders hit at key steps too. Never a template.

03
💰
Fully automated

Money arrives

Messages go out at optimal times. SMS respects TCPA hours (8am–9pm local). Sequences stop the moment QuickBooks shows a $0 balance. You just watch the money come in.

The sequence

45 days of intelligent follow-up

Each email written fresh by AI — escalating in tone until you get paid.

1
Day 1–3
Friendly

Warm, human reminder — assumes the invoice slipped through. Opens a conversation rather than demanding payment.

2
Day 7
Professional

Polite but clear. References the specific invoice, your prior message, and the exact outstanding amount.

3
Day 14
Direct

No ambiguity — payment is needed now. References the overdue history and the full amount with context.

4
Day 21
Firm

Businesslike and serious. Notes the account is significantly overdue and formal attention is required.

5
Day 30
Urgent

Conveys real urgency. Notes that resolution is needed within days and mentions potential next steps.

6
Day 45
Final Notice

Last email. Formal, final, and unambiguous — you decide the next step if there is still no response.

✓ Sequence stops automatically the moment QuickBooks shows a $0 balance — no over-messaging, ever.

Built for how small businesses actually work

Everything you need. Nothing you don't.

✍️

Every email is unique

AI references the specific services, amounts, and client history. Recipients can tell it's written for them — not a template.

Stops the instant paid

Always professional

Firm but never threatening. Dueflo preserves client relationships while still getting you paid on time.

📱

Frequently asked questions

Everything you need to know before you sign up.

Does Dueflo modify anything in my QuickBooks?+

No. Dueflo has read-only access to your invoices. We never create, edit, or delete anything in QuickBooks. Your data stays exactly as you left it — we only read invoice status to detect payments and stop sequences.

What happens when an invoice is paid?+

Dueflo syncs with QuickBooks every 6 hours. The moment an invoice shows a $0 balance, the collection sequence stops automatically — no further emails or texts are sent to that client. You can also sync manually at any time.

Does Dueflo send text messages (SMS) to my clients?+

On Professional and Business plans, yes. SMS reminders are sent at steps 3 and 5 of the collection sequence as an additional touchpoint for clients who haven't responded to emails. Every SMS is TCPA-compliant — only sent between 8am and 9pm in your client's timezone and includes a STOP opt-out. Starter plan is email-only.

Where does Dueflo get my clients' phone numbers?+

Dueflo syncs phone numbers directly from QuickBooks — reading the Primary Phone, Mobile, and Alternate Phone fields from each customer record. If a phone number isn't in QuickBooks yet, you can add or edit it directly from the invoice dashboard without touching QuickBooks.

Can I see what emails are being sent before they go out?+

Yes. Every sent email and SMS is logged in your dashboard with a preview, the step number, and full tracking data (opened, clicked, bounced). You can also exclude specific invoices from collection at any time with one click.

Will my clients know this is automated?+

The emails are designed to read as personal and human-written. Each one references the specific services rendered, the exact amount, and adapts based on prior communication history. Most recipients assume it's written by a person.

What if I want to pause collections for a specific client?+

You can exclude any invoice from the dashboard instantly. The sequence stops immediately and that invoice won't be included in future syncs unless you manually re-activate it.

Do I need a QuickBooks Online subscription?+

Yes, Dueflo integrates with QuickBooks Online (QBO). QuickBooks Desktop is not currently supported. Any QBO plan works — Simple Start, Essentials, Plus, or Advanced.
