Get the fee paid — without risking the client relationship
The client is also next year’s revenue, which is why fees sit unpaid for too long. Rieck follows up in your name and stops the second the client replies.

Very few cases ever go further than a reminder
The follow-up has to sound like you — not like a collection agency
-
The reminder is your message.
Letterhead, sender and tone are yours. The client does not meet a stranger’s name in the inbox, and nobody has to apologise for a system they did not choose.
-
A reply stops the automation.
If the client writes back — even just to ask — the cadence pauses immediately. The case waits for a person, not for the next scheduled dispatch.
-
The engagement carries the fee.
The engagement letter is signed and sits under the invoice. If the amount ever has to be collected, it rests on an agreement and not on an assumption.
The outcomes
Most fees are paid after a single reminder
Only a small share of overdue invoices ever go on to collection. That is why the tone of the first letter matters more than everything that comes after it.
The four places a fee is decided
From the engagement being written to the client being in dialogue
- The engagement
The engagement letter is the foundation, not a formality
Scope, fee structure and payment terms are signed digitally before the work starts. It is the same documentation that later decides whether a discussion about a fee becomes a negotiation or a case.

- Fee structure and terms in the same document
- Sits under every single invoice on the matter
- The fee note
Itemised enough not to be argued about
The fee note is created with hours, disbursements and matter number in place. An invoice the client can follow gets paid; an invoice showing one lump sum gets a phone call — and then it sits still for a fortnight.

- The reminder
Sent on your letterhead, in your tone
The first message is not a chaser — it is a fee-free reminder, sent from you. Most fees are paid right here, and a client who has forgotten an invoice should not be treated like one who will not pay.

- The dialogue
If the client writes, the machine stops
An objection is something a person writes — and it must never be met by the next scheduled chaser. The cadence pauses the second the reply lands, and the case waits for you, not for a date.

Start where it hurts
You do not have to rebuild the whole matter management
Each part can be taken on its own. Most advisory firms start at the reminder — the one nobody wants to send — and add the engagement letter and collection afterwards.
-

Contracts & signing

Our shops invoice on their own, but collection has to look the same across the chain. We can see each case without calling around.
