Billable time to invoices

Record the work.
Prepare the invoice.

I connect recorded time or approved milestones to invoice preparation, so you can see what is ready to bill. Your team checks the client, rate and charge before sending; good capture is what makes the process dependable.

The problem

The fee you earned
and never invoiced

A client asks for a quick call. It runs for forty minutes and it is chargeable. It goes in the diary and nowhere else, so you send yourself an email to remember to bill it. At the end of the month you rebuild the invoice from the diary, the inbox and memory, often in the evening.

Regular work survives this. Ad hoc work does not. The extra call, the additional revision, the site visit that ran over: each one is small, so each one is easy to forget, and together they add up to real money left on the table.

None of it is a question of discipline. It is a question of where the information goes the moment the work is agreed.

If the work is recorded once, it can be invoiced without anyone remembering it.

The change

What it looks like before,
and after

Today, by hand

  • A chargeable call goes in the diary and nowhere else
  • You email yourself a reminder to bill it
  • Hours are added up at month end from memory and messages
  • Ad hoc work slips through, or is billed months late
  • Invoices are written in the evening, one at a time

Once it runs itself

  • A timesheet entry or a diary event marked chargeable becomes a line on a draft invoice
  • Hours flow from the tool that records them to your accounting software
  • Ad hoc work has somewhere to go the moment it is agreed
  • Drafts wait in your accounting tool for you to check and send
  • You can see what has been worked and not yet billed
Deputy → Xerohours recorded once, then invoiced and paid from the same data

My own business · Childcare, London

Before 10PM I ran an after-school nanny agency in London. The time each nanny spent with a child was counted in Deputy and flowed into Xero, so families were invoiced, and nannies paid, for the real time worked, without anyone adding up timesheets.

In practice

From recorded work to a checked invoice

  1. Record the work

    Capture the time, chargeable call, extra or approved milestone in the agreed source.

  2. Match the client and rate

    Use the client, project and agreed billing rules. Flag missing rates or uncertain matches.

  3. Create a draft

    Prepare the invoice lines through a supported accounting connection. Check for duplicate entries.

  4. Check the details

    An authorised person confirms the time, scope, rate and any adjustments.

  5. Send and track

    A person sends the approved invoice, and the record shows what has been billed.

In my own childcare agency, Deputy hours flowed into Xero. A calendar-to-invoice workflow is another option to design around your records and permissions.

How we get there

Three paid phases.
You decide after each one.

The question is never whether you should bill for your time. It is how much of it currently reaches an invoice.

Time Leak Audit

I map how the work happens today, estimate the hours that could be recovered and rank the opportunities against your goals. Under two hours of your time.

Process Design

A working session with your team, then detailed mapping: the steps, the data, the business rules and the exceptions that decide how the build behaves.

Separately scoped · fixed fee

Implementation and handover

I build it in the tools you already use, test it against the agreed scenarios, document it and show your team how to run it without me.

Before any of it, a free fifteen-minute conversation. Bring the process as it actually happens, not as it should.

billing your time.

Do I need to change how I record my time?

The aim is to capture time where it already happens: a timesheet tool, a chargeable diary event or a booking. If nothing records it today, we agree a practical way to start and how to check missing or duplicate entries.

We bill by stage or fixed fee, not by the hour. Does this apply?

Yes, often more so. Stage invoices are triggered by a milestone rather than hours, and the ad hoc work around them, a call, an extra revision, a site visit, is exactly what slips through. The system can catch both.

Will invoices go out without me seeing them?

No. Drafts wait in your accounting software for an authorised person to check and send. The time saving is in preparation, while approval stays with your team.

We use Xero. What about other tools?

I have connected time recording to Xero in my own business. Many accounting and time tools with a proper connection can work the same way, and I check yours before designing anything.

How much did you work last month that never reached an invoice?

If you are not sure, that is the answer. Fifteen minutes, no charge, and we will look at where the gap is.
