Who this guide is for

For security business owners preparing for a sale or reviewing an indicative offer. Use it to separate continuing work, unresolved obligations and the agreed treatment of money.

What you will take from it

  • Separate the business-value illustration from the completion figure.
  • Check guarding assignments, alarm renewals and monitoring obligations against current records.
  • Record each disputed issue once and trace any overlapping treatment.

What is inside

  1. Write down what yes covers
  2. Separate income from continuing work
  3. Price the work the owner leaves
  4. Follow the people and obligations
  5. Give each issue one home
  6. Reconcile the completion figure

The tool: security offer-to-completion issue log

A two-page fillable log for evidence, disputed amounts, overlap checks, responsible people and resolution dates.
