How to Track Additional Work Requested by a Client

Additional work is where many otherwise good jobs become disputed. Treat every meaningful change as a small controlled decision rather than an informal favour.

Keep the original scope visible

You cannot explain a change clearly unless the original quotation, specification and exclusions are easy to find.

Record the request

Note who requested the work, what they asked for, when, why and whether it is urgent. Add photographs or measurements where useful.

Explain the impact

State additional labour, materials, subcontractors, price basis, VAT treatment where applicable, programme effect and risks.

Capture approval

Use a signed variation, email, message or other agreed process. Record any spending limit or provisional instruction.

Track delivery separately

Record when the additional work started and finished, materials used, evidence and any further changes.

Make the invoice traceable

Reference the variation or approval on the invoice so the customer can connect the charge to the agreed change.

Turn the record into a working job tool

Use the record during the job, not only after a problem appears. Before each visit or call, review the latest agreed scope, open actions, promised dates and payment position. After the interaction, add a dated note while the details are still fresh.

Write entries so that another responsible person could understand what happened without relying on memory. Identify the people involved, the decision or instruction, any amount or deadline, and the next action. Where wording matters, preserve the original email, message, photograph or document rather than relying only on a summary.

Keep customer-facing facts separate from estimates, internal opinions and unconfirmed assumptions. A useful status label such as confirmed, proposed, disputed or awaiting approval makes the record easier to interpret later.

Common record-keeping mistakes to avoid

Do not overwrite an earlier entry when circumstances change. Add a new dated update and retain the earlier version so the sequence remains clear. Avoid vague notes such as “customer agreed” unless the note also states what was agreed, when, by whom and how confirmation was received.

Do not keep important evidence only inside one employee’s phone, personal inbox or messaging account. Move business records into the agreed job file and apply appropriate access controls. Avoid collecting personal information that has no genuine business purpose.

Do not treat a tidy file as proof that a contract, debt or legal position is valid. Good records support understanding and evidence, but professional advice may still be required where rights, liability, tax or regulation are disputed.

Use a simple review routine

Review active jobs at a regular interval that suits the pace of the work. Check overdue approvals, incomplete tasks, unanswered messages, promised dates, unpaid amounts and documents that have not yet been filed.

At completion, run a final quality check: compare the finished work with the agreed scope, confirm handover, list any defects or follow-up, issue the correct invoice and record the payment position. Lock or archive the file only when the remaining actions are clearly assigned.

Periodically test whether older files can still be found, opened and understood. Remove duplicates where safe, retain originals that matter, back up important records and follow a documented retention and deletion policy.
