Illustrative example
One repeated service boundary
- Stream
- Support agreement S-44
- Prior invoice
- INV-441 / Oct 1–31
- Proposed interval
- Oct 31–Nov 30
- Shared service date
- Oct 31 / 1 day
- Review decision
- Check agreement before editing draft
Fictional inclusive dates; service overlap is a review signal, not a duplicate-charge finding.
See the recorded product workflowWhat this document helps you record
A billing period register connects each charge to the service interval it covers. It is different from a cutoff checklist, which determines when work enters a billing run, and from payment terms, which specify when the client should pay. Store those dates separately.
Use one explicit date convention for a service stream. This worksheet counts both start and end dates and records agreement, service identity, invoice reference and reviewed status. Shared dates between separate service categories may be legitimate, so record the scope before deciding whether coverage repeats.
The fictional prior period is October 1–31. A proposed October 31–November 30 period shares October 31; a November 1–30 proposal does not. That comparison identifies a date question only. The appropriate charge still depends on the approved service and agreement.

How to complete the template
Name the service stream
Identify client entity, agreement and service category. State whether period endpoints count and keep issue and due dates in separate fields.
Connect prior and proposed coverage
Record billed periods and invoice IDs, then add the proposed interval. Check shared dates, missed service intervals and authorized pauses with evidence.
Resolve before drafting
Document the reason for any legitimate overlap or approved change. Pass the reviewed dates and invoice references to the draft owner, preserving the original register version.

Avoid this
Comparing different services as duplicates
Equal dates do not prove the same charge. Match the scope and agreement before proposing a correction.
Avoid this
Using due dates as coverage dates
A payment deadline says nothing about which service days were billed. Extract the coverage from the actual document or agreement.
Move from reading about the workflow to running it.
InvoiceAgent is designed for the last mile of getting paid: scheduled invoice delivery, reminder timing, professional PDFs, and send-time FX conversion when global billing is involved.

Questions people usually have before changing the workflow.
Are both endpoints included?
Yes in this worksheet. If your agreement uses an exclusive endpoint, adapt the convention consistently before comparing.
Does no overlap prove complete coverage?
No. Check expected service dates and pauses separately; the calculator only reports the intersection.
Does this calculate proration?
No. Review any approved partial-period amount separately from this coverage record.
