Automated follow-ups: quotes, invoices, documents

What happens today

The most expensive reminder is the one you forget.

It isn't a lack of rigour. It's that follow-up has no slot in the day.

Nobody knows what's pending

Sent quotes, overdue invoices, requested documents: the information is in an inbox, sometimes several, never in one place.

The reminder comes too late, or never

The customer chose elsewhere, the invoice is three weeks late, the file waits for a document nobody asked for again.

Every reminder is rewritten by hand

Find the context, the amount, the right tone: ten minutes per reminder, multiplied by everything in progress.

How it works

A due date per item, a reminder to approve.

The workflow watches what has been sent or requested, waits for the delay you set and prepares a draft. Sending remains your decision.

Step 01

The item is logged

As soon as a quote is sent, an invoice issued or a document requested, the item appears in a sheet with the customer, the amount or subject, the date and the reminder due date.

Step 02

The reminder is prepared, not sent

At the due date, if nothing has been detected, a draft is written from your template: tone, wording, signature. You receive it with the context.

Step 03

You decide, the sheet follows

You send, adapt or cancel. The status changes, the next action is noted. A reply, a payment or a received document interrupts the sequence.

What changes

Before and after: what actually changes.

You keep deciding on every reminder. You stop having to think about it.

Situation	Today	With the workflow
Knowing what's pending	Searching through emails	One sheet: item, status, due date, next action
Timing of the reminder	When someone remembers	At the due date you set, for example day 5 then day 12
Writing the reminder	Ten minutes finding the context	Draft ready with amount, date and context, to review
The customer already replied or paid	Risk of chasing by mistake	The sequence stops automatically
Overview	None	Pending, chased or closed quotes, invoices and documents, at a glance

You stay in control

What stays in your hands.

A reminder affects the customer relationship. The workflow prepares and reminds, you keep the last word.

Every reminder is approved

No message goes out without your say-so. You can also choose automatic sending for certain simple cases only, such as small invoices.

You set the delays

A different delay by item type, amount or customer: the rule is yours and changes in one line.

Your tone, your words

The templates are written with you, per reminder type. The draft uses your wording, not a generic text.

Exceptions are planned

Customer not to be chased, dispute in progress, verbal reply: one status is enough to pause the sequence.

Tools involved

Your current tools, connected together.

The workflow plugs into the tools you already use. Compatibility is checked for your case, never assumed.

Illustrative scenario

A tradesperson, a quote and an invoice pending.

A fictional example to show the sequence. The timings and rules are the ones you would choose.

Day 0

Quote sent

Mr D.'s quote leaves from the usual tool. It appears in the sheet with a day-5 due date.

Day 5

No reply detected

A reminder draft is prepared: quote recap, availability for questions, offer of a call. You receive it in the morning.

Day 5, 8:30 am

You approve

You add a line about a possible start date and send. The status becomes “chased once”.

Day 7

The customer signs

The signature is detected, the next reminder is cancelled. The job starts.

Day 45

Invoice 3 days overdue

No payment detected. A polite reminder is prepared with the amount and payment link. You approve in one click. Payment arrives the next day, the sheet closes on its own.

Illustrative scenario: the timings, messages and rules are examples. They are defined with you, from your tools and the way you work. An illustration is not a promise of results.

Frequently asked

Before you ask.

What if my customer replies by phone?

You change the status in one line in the sheet, or by replying to the alert. The sequence stops. It's planned from the start.

My quotes and invoices go out as PDFs by email. Does that work?

Often, yes: sending an email with an attachment from a given address can serve as the trigger. We check what your mailbox allows before committing.

How many reminders?

As many as you decide, usually two or three per item. Beyond that, chasing does more harm than good. You set the number and the delays.

Can I see what's pending from my phone?

Yes. The tracking sheet is a shared Google Sheets or Airtable, accessible anywhere. A weekly summary can also be sent to you.
