Frequently asked
How does the Free plan work?+
Sign up with just an email — no card required. Free gives you 3 invoices a month, 15 clients and 25 products or services, with the customer portal included. It stays free; there is no trial that expires. Upgrade from Settings → Plan & Billing when you need more.
Can I cancel any time?+
Yes. Cancel from Settings → Plan & Billing. You'll keep access until the end of your current paid period. After that, your workspace becomes read-only — you can still log in and export your data.
How does the AI Assistant work?+
Available on the Pro plan. The Assistant uses your real workspace data (clients, items, invoices) to draft invoices, find unpaid invoices, record payments, and more. It's powered by Anthropic Claude via the Vercel AI Gateway, with zero training on your data.
Do you support South African VAT?+
Yes. Set your VAT rate (default 15%) in Settings → Tax Rates. It's applied automatically on every invoice line. Tax reports break out collected vs accrued.
How is my data secured?+
Your data sits in a shared database where every table is protected by row-level security, so one business's queries cannot reach another's rows. Encrypted at rest and in transit. Hosted on Vercel, with the database in the EU.
Can I import from QuickBooks, Sage, or Xero?+
CSV import for clients and items is available on every plan. Direct migration tooling from QuickBooks, Sage, and Xero is on our roadmap. If you need it before then, email us — we'll help manually.
What payment methods do my customers see on the portal?+
EFT. The portal shows what is still owed and your banking details, with the invoice number as the payment reference, so your customer pays straight into your account. Card payments are not available on the portal yet. The portal link is included in every invoice email.
Can I use my own email to send invoices instead of yours?+
Yes — that's actually recommended. From the invoice detail page, click 'Download PDF', then attach it to your own email. Better deliverability + more personal than a generic noreply@ sender. The 'Email via DDM Flow' button exists too if you want automation.
