Invoice Analysis for Accountants With Many Clients

You keep the books for dozens of companies, and your clients increasingly ask "where did the money go last month?" Here's how to produce and hand over a per-client analysis dashboard without building a separate Excel report from scratch each time.

Many Clients, Many Reports

An accounting firm keeps the records and filings for dozens of companies. But clients no longer wait only for their declarations; they show up with questions — "which supplier did I pay the most?", "how did my VAT burden break down?", "where did I spend more this month than last?" That's analysis work, well beyond bookkeeping.

Building that report in Excel for a single client is doable. The trouble is repeating the same work for every client — as the client count grows, the effort grows in lockstep.

The Manual Way: One Excel per Client

The familiar routine: stand up a separate workbook for each company — dump the invoices, total them by supplier, separate out the VAT, draft a summary, and send it over.

What wears you down is that the work is repetitive:

The real value for a client comes from the analysis that sits alongside the filing. But building that analysis by hand for every client rarely fits an office's time budget.

Producing a Dashboard per Client

Standardize the workflow and you can produce the same quality of analysis for every client in minutes. EFaturaFlow turns each client's e-invoices into a structured analysis and packages it as a file you can hand straight to the client.

1 Upload the client's e-invoices

Upload the company's e-invoices for the period (PDF or HTML). The client can download these from their accounting software or the Turkish Revenue Administration (GİB) portal and send them to you.

2 The analysis is generated automatically

Supplier distribution, VAT breakdown, line-level detail, and period-over-period trend are prepared automatically. Same structure, same quality, for every client.

3 Hand it to the client

Download the dashboard as an offline HTML file or Excel and email it to the client. No account, no login required on their end — the file works entirely on its own.

Tip: Because the output is consistent across clients, it gradually becomes your office's standard "monthly analysis report." Each client receives a familiar report in the same format, month after month.
