Sorry, it slipped through with the month-end close. We'll pay it on Friday.18:51
Perfect, I've noted it down for Friday the 17th. Here's the link in case you want to pay sooner: pay.zeryx.io/l/8K2P18:52
Payment promise
Friday 17 · €8,750
02Agrees and collects

An agreed date. A link to pay.

When the client says “Friday,” Zeryx notes it down and comes back on Friday. When they say “now,” it sends them a link to pay by card or bank transfer, and the payment is matched to your invoice. No chasing, no losing track.

You decide how far it goes.

Which clients are off-limits, what tone, how many messages and when to stop. At first you approve every message; once you trust it, you grant permission by client or by amount. Zeryx doesn't negotiate discounts or make threats: it asks, agrees and collects. And everything it does is on record.

(03)How it works

Here's how Zeryx collects, step by step.

0105
01Imports

The invoices you create with Zeryx, or the ones in your Odoo.

Zeryx sees which invoice is overdue, who owes it and since when. You mark which clients are off-limits and which amounts you want to approve first.

ZeryxOdooExcluded clients
02Asks

Writes on your behalf and asks what’s going on.

On WhatsApp, and by email if they don’t reply. In your tone and without cold templates: “Is anything holding up the payment?”

WhatsAppEmailYour tone
03Agrees

Listens to the answer and logs the date.

If the client says “Friday,” Zeryx notes it and follows up on Friday. If there’s a dispute, it hands it to you with full context.

Payment promiseDisputesFor you
04Collects

A link to pay. The payment, matched to its invoice.

Card or bank transfer, no sign-up. When they pay, the invoice shows as collected in your dashboard and your client gets their receipt.

Payment linkReconciliationReceipt
05Reports

Every morning, the summary. Always, the record.

What was collected, what was promised, who isn’t replying and what needs your decision. Every message is on record, with date and time.

We don't ask you to believe us. We measure it.

Control
Half for Zeryx, half for you

We split your overdue invoices at random. Zeryx handles one half; you keep handling the other the way you do today. Same clients, same month.

Random splitSame clients90 days
Scoreboard
Collection points over your control

After 90 days we compare what share of the overdue money was collected in each half and how much came in through the link. A number, not an opinion.

Ten points more, or we refund your fees

If in three months Zeryx doesn’t collect at least ten points more than your control, we refund what you paid. No questions asked.

How your client pays
One link. No sign-up.

Your client opens the link, sees the invoice and pays. The money goes from their bank to your account; Zeryx just matches it to the invoice.

Reconciliation
Every payment goes back to its invoice
When your client pays through the link, the invoice is marked as paid on its own. Bank transfers, as soon as you reconcile them in Odoo or mark them in Zeryx.

(09)Questions

What everyone asks before getting started.

Something else? Message us on WhatsApp and we'll answer you ourselves, not a bot.

Not at first: every message goes through your approval. Once you trust it, you give it permission by client or by amount. You choose the tone, the hours and which clients are never contacted.

The way your best admin would: politely, on your behalf and without threats. It asks if anything is holding up the payment, listens, agrees on a date and follows up that day. It doesn’t negotiate discounts or talk about lawyers: if there’s a dispute, it hands it to you with full context.

One day. If you invoice with Zeryx, your invoices are already in; if you use Odoo, we connect it; if you use other software, you upload your invoices in an Excel file. You mark the clients you don’t want us to contact and Zeryx starts on the overdue ones that same afternoon.

With Zeryx Invoicing and with Odoo. If you use other software, you can upload your invoices in an Excel file. And if you want us to connect to yours, let us know: it’s the first thing we ask.

In your account, as always. When your client pays through the link, the money goes from their bank to your account through the payment gateway; Zeryx doesn’t touch it or hold it. What it does is match that payment to your invoice.

With the Mid-size plan, you measure it yourself: Zeryx handles half of your overdue invoices and you keep handling the other half the way you do today. After three months we compare. If we don’t collect at least ten points more than your control, we refund your fees.

No. You pay month to month and stop whenever you want. And the price is the same for everyone: we make no exceptions.
