How do I put together monthly reports for clients?
A good monthly report does not describe the work, it justifies it. One page, the same sections every month, sent to the client at the start of the month. With 12 retainer clients and hand-written reports, that costs you about 8 hours a month.
Short answer
- Fix the same structure every month: hours, deliverables, retainer status, what comes next.
- Pull the hours straight from the timesheets, grouped by activity, not rewritten from memory.
- Show retainer hours included versus hours consumed, with the difference in plain sight.
- Add the deliverables handed over, with their dates.
- Send the report to the client in the first days of the month.
What the rules say (in brief)
- The activity report is the supporting record behind the hours you bill, so keep it with the client file.
- Whether VAT applies to your services depends on your own VAT registration; check it with your accountant.
- Electronic invoicing rules differ by country, so check the rules where your client is based.
- Do not put third parties' personal data in the report without a basis — the GDPR covers annexes too (Regulation (EU) 2016/679).
Practical examples
- A monthly retainer for 20 hours: the report shows 26 hours consumed, so the effective rate fell by about 23%.
- Those 6 hours over the retainer, shown on the 3rd of the month, can still be billed; found three months later, they never are.
- 12 retainer clients × 40 minutes of hand-written report = 8 hours a month spent only on reporting, time you cannot bill.
The structure of a one-page monthly report
| Section | What it contains |
|---|---|
| Hours by activity | Design, development, content, meetings — with the billable total |
| Retainer | Hours included, hours consumed, the difference either way |
| Deliverables | What was handed over, with dates |
| Domains and hosting | This month's renewals and what expires next |
| Next month | What is being worked on and what you need from the client |
Common mistakes
- Sending the report only when the client asks — then it reads as an excuse, not a routine.
- Writing activities instead of outcomes: „worked on the site” says nothing about the deliverable.
- Hiding the retainer overrun to keep the client happy, then paying for it out of your margin.
- Rebuilding the report by hand every month, although the hours are already in the timesheets.
How 4webagency helps
- The hours, projects and retainer data a report needs already sit in one account, so you assemble it from there, not from scratch.
- Retainer status sits next to the timesheets, so an overrun is visible before the month closes.
- Domain and hosting renewals due this month sit in the same account, so they can go into the same report.
- Send the report on the same day as your monthly billing, in the first days of the month.
