What to Do About Clients Who Send You Invoices Badly

It's the 9th of the month. You set up the shared folder. You sent the monthly checklist. You even did a 20-minute Zoom walking the client through it. And this morning, you opened your inbox to: "Olá, só para avisar que ainda não tive tempo de organizar — envio tudo num zip hoje à noite."

Every Portuguese accountant has a handful of these clients. The system exists. The client just won't use it. They send paper invoices photographed at angles. They forward emails with twelve invoices buried in the signature thread. They drop a folder named "faturas março final final v2" and expect you to sort it out — situations that a proper complete guide to invoice automation helps you prevent from the start.

Setting up the workflow was the easy part. We've written about that already. The harder conversation is what you do when the workflow exists and the client ignores it anyway.

The Real Problem Isn't the Invoices

The invoices are a symptom. The real issue is that your price, your scope, and your boundaries don't match the work this client actually generates.

If you're charging €180/month for bookkeeping and the client costs you six hours of chasing, reformatting, and reconciling — you're losing money on that client every month. Every other client in your book is subsidizing their chaos. The fix isn't a better folder structure. It's a conversation.

Most accountants avoid this conversation because it feels uncomfortable and because the last time they raised fees, a client pushed back hard. So they keep absorbing the cost, swallow the weekend hours, and resent the client silently. Eventually something snaps — usually in April, when IES is due and the backlog from three problem clients has compounded.

There's a better way. It requires treating "the client won't follow the process" as a business problem with levers you can pull, not a personality flaw you have to tolerate.

1. Name the Behavior, Not the Client

The first step is diagnostic. Before any fee change, script, or termination, you need a clear picture of what specifically is happening.

Pick three to five of your hardest clients and spend 20 minutes on each. Write down, for the last three months:

• How the invoices arrived (email, WhatsApp, photo, zip, paper bag at the office)
• How many came after the agreed cutoff
• How many needed manual renaming or reformatting
• How many missing invoices you had to chase a second or third time
• Approximate extra hours per month, per client

You're looking for patterns, not gut feelings. One client might send everything late but well-organized — annoying, but low cost. Another might send on time but in such a mess that reformatting takes three hours. These two clients need different interventions.

The point of writing it down is that when you have the conversation, you're not saying "you're difficult." You're saying "in March you sent 47 invoices on the 11th, of which 12 needed renaming and 6 were duplicates. That took me four extra hours."

Specifics change the conversation. Vague complaints sound like whining.

2. The Education Script (Use It Once)

Every problem client deserves one serious, structured conversation before any fee change. Not a WhatsApp message. A real meeting — in person or video — with a shared screen and a written follow-up.

Here's a template that works:

"Quero partilhar consigo como está a correr o fluxo de faturas. Nos últimos três meses, recebi em média [X] faturas depois do dia 5, o que significa que o fecho mensal fica apertado. Também tenho estado a reformatar ficheiros e a corrigir nomes, o que me está a tirar cerca de [Y] horas por mês.

O acordo original era que as faturas entrassem na pasta partilhada à medida que chegassem, com o nome original. Quero perceber o que não está a funcionar desse lado — falta de tempo, sistema não prático, alguém diferente a tratar disto? Dependendo da razão, podemos ajustar."

Three things this script does:

1. States the facts with numbers. Not feelings.
2. References the original agreement. You're not moving the goalposts.
3. Asks a diagnostic question. Maybe the client genuinely has a reason (the person who used to upload left; their email system changed; they're handling 3x more invoices than a year ago). Maybe they just haven't prioritized it. Either answer tells you what to do next.

After the meeting, send a written recap within 24 hours. "Thanks for the conversation. Here's what we agreed: [specific commitments, specific deadlines]. Let's review in 30 days." This recap is the paper trail you'll need if things don't improve.

3. Fee Structure Is Your Main Lever

If the client says "I can't do it, my business is too small for a full-time bookkeeper and I'm overwhelmed" — that's a real answer. It doesn't mean you tolerate the chaos. It means you price it in.

Portuguese accountants typically underprice problem clients because fees are set when the relationship starts, and scope creeps silently. A few ways to restructure:

Tiered pricing by invoice volume and cleanliness. A base fee covers X invoices per month, uploaded to the shared folder in original format by day 5. Above that volume, or for invoices arriving after day 5, a per-invoice surcharge applies. You send a monthly line-item invoice so the client sees exactly what their behavior costs.

"Organization service" as a separate line. If the client won't or can't organize invoices themselves, offer it as a priced service — say, €50-€150/month on top of bookkeeping, depending on volume. Some clients happily pay to not deal with it. Others suddenly discover they can manage their own files.

Annual price review tied to workload. Put a clause in your engagement letter: fees are reviewed yearly based on actual workload, with documented metrics. This normalizes fee increases. They stop being a confrontational event and become an annual administrative task.

Pricing is the most durable intervention. A folder structure depends on willpower. A price schedule just runs on its own every month.

4. Automate What's Still Yours to Do

Some clients will never be organized. You've diagnosed it, you've had the conversation, you've repriced the engagement. The invoices still arrive as blurry photos on WhatsApp on the 10th.

At this point, you have two choices: absorb it at the new price, or reduce the time cost so it stops mattering.

Automation narrows specifically to the mechanical parts the client was supposed to do — extracting NIFs and amounts, detecting duplicates, renaming files, updating the register. If a tool can convert a blurry photo of an invoice into a clean line in your SAF-T register in 30 seconds, the client's chaos stops being your problem. You bill for the "organization service," run it through automation, and pocket the margin.

This is also the point where clients who were paying the surcharge start asking: "pode ajudar-me a configurar o vosso sistema para eu enviar melhor?" Once the cost is visible on a monthly invoice, behavior changes faster than any Zoom call will achieve.

5. When to End the Relationship

Some clients should not be your clients. The signs are consistent:

• You've had the conversation, followed up in writing, and six months later nothing has changed.
• The fee increase was refused or negotiated back down.
• The client treats you like administrative support, not a professional advisor.
• You dread seeing their name in your inbox.
• They're the reason you worked the last three weekends.

Ending an accounting relationship in Portugal is more structured than in some countries — there's a handover of records, a notification to AT if you're the designated TOC, a final period of overlap. Plan for it. Don't fire the client in anger on a Friday night.

A professional termination script:

"Após a nossa última revisão, e tendo em conta a evolução do volume e complexidade da contabilidade, chegámos à conclusão que a nossa estrutura atual já não serve bem os vossos interesses. Vamos encerrar a prestação de serviços a 30 de [mês + 3 meses], com período de transição para o novo contabilista. Preparamos um dossier completo de handover."

Three months is typical. It gives the client time to find a replacement and lets you close the year-end cleanly. Send it in writing, stick to the date, and don't negotiate the reasoning. If you've kept the paper trail from step 2, there's nothing to debate.

The firing you'll regret is not the one you did. It's the three you didn't do, which cost you clients who were actually good to work with because you had no capacity left for them.

What to Do Differently This Month

You don't need to do all of this at once. Pick two clients this week. Write down the specific cost of their behavior over the last 90 days. Book one conversation. Draft one fee increase letter.

A year from now, either the client will have shaped up, the fee will reflect reality, or you'll have a lighter book with better margins. All three outcomes are better than the current situation.

If your accounting practice has more problem clients than you can handle one-at-a-time, Faturiza's multi-client workspace for accountants takes the mechanical work — extraction, deduplication, SAF-T-ready register — off your plate, so your time is spent on the conversations that actually change client behavior, not on renaming files.
