A FEW USEFUL ANSWERS
Before you get started.
Is DueHarbour an accounting package?
No. DueHarbour focuses on invoice tracking and collection follow-ups. It does not replace bookkeeping, tax returns, bank reconciliation or professional accounting advice.
Does it automatically know when someone pays?
No. Record payments manually and check the latest balance before contacting a client. Invoices can be added individually or imported from spreadsheets.
How are reminders sent?
Prepare a reminder in DueHarbour, review the recipient and balance, then select Send reminder. Replies go to your sign-in email. Delivery results appear on the invoice. You can also use your own email app and record a manual reminder. Sending is limited to one email per recipient in 24 hours and 100 per workspace in 24 hours. For automatic reminders, save your business profile, approve a schedule in Reminders and enrol individual invoices. Background checks run every 15 minutes. Scheduled replies go to your business email. Paid, void, paused and held invoices are excluded once their status is recorded in DueHarbour.
How do I subscribe?
Open DueHarbour, sign in with your email verification code, then choose Start my free month. Confirm your subscription and payment details on Stripe. New subscribers get 30 days free, then £12/month unless cancelled before the trial ends. Signing in or taking the tour does not start a trial. After Stripe confirms your subscription, save your business profile and add or import your invoices.
What happens when I cancel?
Cancel future renewals in Settings → Manage billing. Your access continues until the trial or paid period ends. Afterwards your workspace becomes read-only, with existing records and exports still accessible. Cancellation does not delete your data.
Where is my workspace?
Sign in at app.dueharbour.co.uk with the same account each time. This public website contains product information and sample screenshots, not your customer records.
