Productized offer · Accounts receivable
DueDate watches every unpaid invoice and chases it in your voice — polite, persistent, perfectly timed. When a reply needs actual judgment, it stops and hands you the full thread with a suggested next step. You get paid faster without becoming the bad guy.
Five invoices on the board.
One of them will need you.
The problem
Late payment is rarely malice — it's inertia. Your invoice sits in a queue, and the queue responds to exactly one thing: polite, persistent pressure. Which happens to be the job you avoid most.
Chasing feels awful, so it doesn't happen. You'll send the reminder tomorrow; tomorrow you're busy. Most freelancers wait over a week past due before saying anything — and clients learn your invoice is flexible in a way their rent never is.
It's cash flow, not profit, that strangles a small agency. Every week an invoice ages is a week you're the client's bank — at 0% interest, while your own bills arrive on time.
The late payer is often the client you like most. You need the money and the relationship — and a reminder written at 11pm is always either too soft to work or too sharp to take back.
How it works
DueDate plugs into Xero, QuickBooks or Stripe and reads your invoice history: who pays on time, who needs three asks, what you wrote last time. Your past emails set the voice — not a template.
It runs live but sends nothing without your tap. You see exactly what it would send, to whom, and when — and we agree the recovery bar in writing before anything goes out alone.
Sequences run on your rules: how many touches, what tone ceiling for which client, when to stop. Disputes, excuses and anything unusual land on your desk with the full thread — never a fourth nudge.
The difference
Same overdue invoice, two follow-ups. Left: the template your software fires at everyone. Right: DueDate, after one week with your sent folder and this client's payment history.
"Dear valued customer, This is an automated notification that invoice INV-1140 totalling $7,800.00 is now 21 days overdue. Please arrange payment immediately to avoid further action."
Identical for your best client and your worst payer. Formally rude to both — passive-aggressive in a way you never intended.
"Hi Rob — hope the launch went smoothly last week. INV-1140 ($7,800) slipped past due on Friday; I know month-end is chaos at Copperline. If it's already with finance, ignore me — if not, the payment link below takes two minutes. — You"
Pricing
No percentage of collections. No per-invoice meters. You know the number before we start — and you know what "working" means.
Questions
Both, in that order. Week two is shadow mode — every nudge waits for your tap. Once a sequence earns your trust you can let it send solo, per client and per tone level, in writing. Final notices always wait for you. Autonomy is earned, never assumed.
Xero, QuickBooks and Stripe invoicing out of the box. Anything else with an API or a CSV export gets wired up in week one. Your books stay where they are — DueDate reads invoices and writes back payment status. Nothing more.
Rules you sign off before launch: a maximum touch count per invoice, a tone ceiling per client, and triggers that end automation — a disputed line item, a promise-to-pay date, an excuse that needs judgment, any reply with real content. The handover arrives with the full thread and a suggested next step. It never argues with a client.
They get their own rules — or a complete freeze. Your biggest account might get a single gentle note, nine days past due, in your most diplomatic register, and nothing automated above it. Per-client tone and ceilings are set during shadow mode, and you can pull any client out with one message.
Invoice and contact data lives on infrastructure I control and document, hosted in the EU/UK if that's where you are. It's never used to train anyone else's model and never sold. The pilot agreement includes a plain-English data processing clause — or I sign yours. Deletion is part of offboarding, in writing.
