How it works

Three steps from signup to paid.

Set up in five minutes. Send invoices in seconds. Get paid in ways your customers actually use — card, EFT, or QR.

01

Set up your workspace

Add your business details, banking info, and your first clients. Or skip — DDM Flow lets you bill anyone on the fly with one-off names.

02

Create invoices — or ask AI

Click 'New invoice', pick line items, hit save. Or with the Pro plan, tell your AI assistant: 'Invoice Acme R12,500 for May, net 30.' Done.

03

Get paid, automatically

Customers pay via Paystack card checkout, EFT, or QR — all from the same link. Payments reconcile to invoices automatically.

FAQs

How does the 7-day free trial work?+

Sign up with just an email — no card required. You get full Pro access for 7 days. At the end, pick a plan (or don't — your data stays exportable). We'll send a reminder before the trial ends, never an auto-charge surprise.

Is the AI assistant available right away?+

Yes — the AI assistant is included on the Pro plan and during the 7-day trial. Ask it to draft invoices, chase overdue payments, summarise your books. It uses your business data via the same API your team uses.

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, you just can't issue new invoices.

Do you support South African VAT and tax compliance?+

Yes. Set your VAT rate (default 15%) in Settings, and DDM Flow applies it automatically on every line. Tax reports break out collected vs paid. Invoice numbers are sequential and auditable.

How is my data secured?+

All data lives in your dedicated Supabase workspace with row-level security — no other customer can see your data. Encrypted at rest and in transit. Hosted on Vercel (SOC 2 certified). Backups are managed by Supabase.

Can I import from QuickBooks or Sage?+

CSV import for clients and items is available on every plan. Direct migration tooling from QuickBooks and Sage is on the roadmap — talk to us if you need it before then and we'll help manually.

Stop chasing paper. Start chasing payments.

Try every feature for 7 days. No credit card. Cancel before the trial ends and your data is yours to export.
