Invoicing

Log delivered shifts, send the invoice, and track what comes back.

How invoicing works

Sessional turns delivered shifts into invoices, sends them as signed PDFs, and tracks the money without turning you into the chaser.

Not every shift becomes a Sessional invoice. Agency-managed and PAYE-at-source shifts skip the invoice step entirely.

What gets invoiced

Invoices from shifts

Basic

Build an invoice from one or several delivered shifts, with hourly or daily rates per profession.

Signed-link delivery

Core flow

Each invoice emails as a PDF with a 30-day signed link. The organisation marks it paid or raises a dispute with no account.

Auto-chasers

Basic

Overdue invoices chase at day 14, 21, and 28, each attaching the original PDF, cooldown-protected against double-fire.

Revoke a link

Basic

Revoke any individual signed link from your dashboard. Revoked links stop working.

Shift pay-check

Basic

Mark each delivered shift paid correctly, short paid, or not paid yet, across every employer in one view.

Invoice lifecycle

Draft
Invoice created but not yet sent.
Issued
Invoice sent to the organisation.
Acknowledged
The organisation has confirmed receipt.
Paid
Payment received.
Overdue
Payment not received by the due date.
Void
Invoice cancelled and kept for audit.

Invoice numbers

Invoice numbers follow the format SES-YYYYMMDD-XXXXXX using a cryptographically random suffix to prevent guessing.

Sending invoices

Once an invoice is issued, you can send it by email as a signed PDF. The organisation can open the link with no account, see the invoice detail, and either mark it paid or raise a dispute.

Note
Some NHS organisations still require submission through their own portal. The email is a convenience. Submit it through the organisation's usual channel as well if needed.

Payment tracking

Move invoices through statuses as payments progress. The dashboard shows outstanding, overdue, and acknowledgement states at a glance.

Payment tracking is available on the Basic plan and above.

HMRC record keeping

Keep regular CSV exports so your offline records stay in line with HMRC requirements. Sole traders should keep tax records for at least 5 years after the 31 January submission deadline for the tax year. Limited companies should keep records for 6 years from the end of the company financial year.

Batch invoicing

You can bundle multiple delivered bookings from the same organisation into one invoice. Use the bookings page to select the shifts you want, then create the invoice from there.

Tip
Use the organisation filter first if you want to isolate one employer before batching.

Voiding and regenerating invoices

Invoices are immutable once generated. If you need to correct a detail, void the invoice, update the booking or profile information, and generate a new one.

Important
Voided invoices stay in your records permanently for HMRC compliance and cannot be deleted.

Frequently asked questions

Can I combine bookings from different organisations on one invoice?
No. Each invoice is tied to a single organisation. If you have bookings at multiple organisations, create separate invoices for each.
What happens if an organisation does not acknowledge my invoice?
You can resend the invoice email. If the payment due date passes without payment, the invoice moves to overdue status and the auto-chasers continue.
Do agency-managed and PAYE-at-source shifts create invoices?
No. Those shifts skip the invoice step entirely.
