How accounting firms can stop chasing clients for documents (with automated reminders)

Why chasing documents costs more than it looks

Chasing rarely shows up in a timesheet. It is five minutes here to find last month's email, five minutes there to rewrite the same polite message, and a mental note to "check again on Thursday". Spread across every client, every month or quarter, it adds up — and it usually lands on the most experienced people, because they know what each client owes.

The hidden cost is not only time. Manual chasing is inconsistent: some clients get three emails, others none, and nobody can say at a glance who is holding up the work. That uncertainty is what makes deadlines stressful.

What an automated document chaser actually does

An automated chaser is not a chatbot and doesn't need AI. It is a small set of rules that runs every working day:

1. Reads your client list (a Google Sheet or Excel file): client name, email, documents requested for the period, documents received, number of reminders sent and the date of the last one.
2. Works out what each client is missing — requested minus received.
3. Decides what to send: nothing if everything has arrived, a first request if nothing has been sent yet, a reminder if the last email was at least a few days ago, or a "call this client" flag after the last reminder.
4. Sends a personal email from your own mailbox (Google Workspace or Microsoft 365), listing only the missing items, so clients reply to you as usual.
5. Updates the list (reminder count and date) and sends the office a short summary.

You can see exactly this logic running, with fictional clients, in our interactive document chaser demo — no sign-up needed.

How to set it up, step by step

1. Standardise the checklist per client type

Most firms already know what they need from a monthly bookkeeping client, a quarterly client or a payroll client. Write it down once: bank statements, purchase invoices, sales invoices, card terminal reports, payroll summaries — whatever applies. The automation is only as good as this list, and writing it once is usually where most of the time savings come from.

2. Build one client list

One row per client per period, with these columns: client, email, requested, received, reminders sent, last reminder. Whoever records incoming documents ticks them off in received. That single habit is what stops the reminders automatically.

3. Write three short templates, with a tone ladder

• First request — friendly, lists the documents and says the client can simply reply with the files attached.
• Reminder — short and specific: "we're still waiting for these documents", only the missing items.
• Second reminder — firmer, with a clear date by which you need them and an offer to help if something is unclear.

4. Choose the rhythm and the stop rules

Five days between emails is a good default: long enough not to annoy, short enough to keep the deadline in view. Send on working days only, in the morning.

5. Test on three to five clients, then go live

Run it first with internal test addresses, then with a handful of friendly clients. Check that the right documents are listed, that replies land in the right inbox and that ticking "received" really stops the next reminder. Then switch it on for everyone and read the weekly summary instead of hunting through email.

Common mistakes to avoid

• Reminding clients about documents they already sent. If "received" isn't updated, the automation will nag the wrong people. Make ticking it part of the routine when files arrive.
• Sending from a no-reply address. Clients answer reminders with attachments and questions. Send from the mailbox they already know.
• Emailing forever. After two reminders, more email rarely helps; a short phone call does. Build that escalation in.
• One giant generic message. "Please send all outstanding documents" gets ignored. A list of the two specific items still missing gets answered.
• Starting with a new portal. Asking clients to create accounts and learn an upload tool adds friction. Start with email and a list; add an upload folder later if you need it.

Which tools to use

You have two broad options. Dedicated client-portal software gives you a ready-made upload area and reminders, usually for a monthly subscription, and your clients need to use the portal. An automation on your own tools — n8n, Make or Zapier connected to Google Sheets or Excel and your Gmail or Outlook — keeps everything in the accounts you already have, with clients replying by email as they do today. The second option is what we build, as a one-off setup in your own accounts.

Whichever you choose, check data protection basics: the emails go from your account, the list holds only what is needed, and anyone who builds or maintains the automation for you should sign a data processing agreement (art. 28 GDPR). Our data & privacy page explains how we handle this.

Is it worth automating?

As a rule of thumb, if your office sends more than about 30 document reminders a month, an automation usually pays for itself within a few months. Below that, a shared checklist and a calendar reminder may be enough. Put your own numbers into the Chasing Cost Check to see the hours and the yearly cost for your firm.
