Send this to your assistant

Create a ClickRuntime automation: every Monday at 7:30am, email me a list of overdue Wave invoices with customer, due date and amount due, sorted by the oldest first.

Paste it into your assistant. It tells you what it will send or change before it runs live.

Why use it

Why teams use this automation

Late payments hurt small businesses quietly. Wave marks invoices as overdue when the due date passes, but nothing tells you which ones are affected, how late they are, or whether the same client keeps appearing. Without a weekly look, a 30-day invoice slides to 75 days, the client's attention moves on, and the money is collected only after an uncomfortable conversation, if at all.

Every week the automation queries Wave for invoices with the OVERDUE status and emails you a list: customer, invoice number, amount and due date. You get a single sheet to work from, such as making calls on Tuesday morning, rather than a hunt through the Invoices page and a mental note of who owes what.

It is especially valuable for service businesses that bill after delivery and carry real cash risk in unpaid invoices.

What you get out of it

Chase while the invoice is still fresh
A client who is two weeks late usually pays after a polite nudge. One who is ten weeks late often needs escalation and sometimes never pays. A weekly list keeps you in the first group, where collecting is cheap and friendly.
One list to work through on a set day
Having every overdue invoice in a single email turns collections into a thirty-minute task you can schedule, rather than an item that never gets time because nobody can see how big the problem is.
See repeat late payers
If the same customer is on the list month after month, that is a pattern worth acting on with shorter terms, a deposit up front or a late fee written into the next quote, instead of repeating the same chase.
Know the total owed to you
Adding up the overdue amounts shows how much cash is waiting outside your account, which helps when deciding on a purchase or a hire and when explaining a cash squeeze to a partner or a lender.
Evidence for a collections conversation
The email shows due dates, so you can say exactly how many days late an invoice is when you call, and the client cannot easily claim it was only sent recently or that they never saw it.

Build your own

Need it to work differently?

This template is a starting point. Copy the prompt and change it, or describe a different automation from scratch, with your own conditions, more apps or an AI step. Your assistant writes it, tests it and runs it on ClickRuntime.

Your own rules
Conditions, thresholds, filters and exceptions, written the way you'd explain them to a colleague.
Any number of apps
One automation can read from one app and update several others. Over 248 apps are ready, and anything with an API works too.
AI where it helps
Summaries, classification, extraction and drafts use ClickRuntime's built-in AI, with no extra key.
On a schedule or on each event
Runs as often as every 5 minutes, or the moment an app sends an event, and keeps track of what it already handled.

Changes you can ask for

Run it at a different time, more or less often, or only on weekdays
Add an AI step, for example to summarize, sort or draft a reply
Add another app, for example also send it to Slack
Combine it with other Wave steps into one automation

Under the hood

The code that runs this automation

This is the Python script that runs each time the automation starts. Your AI assistant writes it for you when you send the prompt, and you allow each step in your assistant. To change how the automation works, describe the change to your assistant and it updates the script for you. For every function it can use, see the script reference.

overdue_invoice_digest_wave.pyexample

from clickruntime import on_trigger, credentials, http, notify

BUSINESS_ID = "your-wave-business-id"

def wave(query, variables=None):
    token = credentials.connection("wave", "work")
    resp = http.post("https://gql.waveapps.com/graphql/public", headers={"Authorization": f"Bearer {token}"},
                     json={"query": query, "variables": {"biz": BUSINESS_ID, **(variables or {})}})
    return resp.json()["data"]["business"]

QUERY = """query($biz: ID!) { business(id: $biz) { invoices(status: OVERDUE, pageSize: 100) {
  edges { node { invoiceNumber dueDate customer { name } amountDue { value } } } } } }"""

@on_trigger
def run(event):
    invoices = sorted((e["node"] for e in wave(QUERY)["invoices"]["edges"]), key=lambda i: i["dueDate"])
    lines = [f"{i['dueDate']}  {i['customer']['name']} #{i['invoiceNumber']}: {i['amountDue']['value']}" for i in invoices]
    notify.email_me(f"{len(lines)} overdue Wave invoices", "\n".join(lines) or "Nothing overdue.")
    return {"count": len(lines)}

FAQ

Common questions

Which invoices does Wave treat as overdue?

An invoice becomes overdue when it has been sent, is not fully paid, and its due date has passed. Drafts and paid invoices are not included, so the list contains only bills you are actually waiting on, with nothing you need to ignore.

Will the same invoice appear in every weekly email?

Yes, for as long as it stays overdue. That is intentional: the digest is a standing worklist, and an invoice disappears from it only once it is paid or its status changes in Wave, so nothing quietly falls off the list.

Can I send the digest to my bookkeeper too?

Yes. The email can go to several addresses, so a bookkeeper or partner receives the same list on the same morning. Tell your AI assistant who should be included, and you will see the recipient list before it runs.

What permissions does it need?

full access token. Nothing else in your accounts is used.

Does it need AI?

No. It runs without AI, so it doesn't use your plan's AI allowance.

How many runs does it use?

One run each time it runs (weekly). Checks that find nothing to do and stop right away aren't counted.

Can I change how it works?

Yes. Describe the change to your AI assistant, for example a different schedule, channel or filter. It updates the automation, tests it and tells you what changed.
