What it means
A buyer may order equipment that must be installed before use, and the installation record connects the physical work with the purchase order, location, asset identifier and contract scope. It may include photographs, serial numbers, test results, parts used and the signatures of the installer and site representative.
Name the person who inspected the work and the basis of their sign-off, since a signature can acknowledge attendance, receipt or completion, which are different decisions, and use a field that states exactly what the signer confirms. The distinction between "installed" and "accepted" matters.
A generator can be bolted into place while wiring tests remain open, and a software system can be deployed without every user workflow working. If the contract links a payment milestone to installation, read the exact completion criteria, because a generic sign-off form may not satisfy them.
Keep an open-item register with the completion record and attach evidence for each closed item, recording follow-up tests separately. An exception that affects safe operation should be escalated rather than hidden in a note.
Record exceptions honestly: a missing panel, damaged component or inaccessible area should appear on an open-item list with an owner and target date, because a form marked "complete" while workers plan to return next week misleads operations and finance. If a customer signs only to acknowledge attendance, the document should say so rather than imply final acceptance.
The record can also help asset management, because serial numbers, installation date and location support warranties and future service. It also helps determine when an item became ready for intended use, though the accounting start date depends on the actual facts and relevant standard.
Managers should not automatically start depreciation merely because a delivery note was signed. Installation may involve safety or statutory checks, and the required inspection and approval differ by equipment and place, so this entry does not state a universal permit or certificate requirement; the project team should check applicable rules and qualified roles.
For managers, the document is a handover bridge. It makes the physical state clear to the customer, the maintenance team and finance, without pretending that installation finishes every remaining test or obligation.
In practice
Real-world examples.
Example
An air-conditioning contractor records the model and serial number of a unit installed in a specific office, with one control test still awaiting a follow-up visit. The record lists the open test with an owner and a target date. The office manager can see exactly what is finished and what is not.
Example
A restaurant's oven is delivered on Monday and installed on Tuesday. The team records the installation separately from the later safety and operating checks. The oven is not used for service until those checks are signed off.
Example
A site manager signs a record confirming that technicians attended and fitted the equipment but notes a missing guard. Final acceptance remains open until the guard is fitted and checked. The signature wording makes clear that it confirms attendance and fitting only.
Formula
Calculation
Installation completion share = Agreed installation items recorded complete / Agreed installation items due x 100
Remaining installation items = Items due - Items confirmed complete
Worked example. A project calls for 20 units. Installation records confirm 18 are fitted; two are still awaiting parts.
- Completion share = 18 / 20 x 100 = 90%.
- Remaining items = 20 - 18 = 2 units remain uninstalled. Separate tests and acceptance may still be required for the 18 fitted units.
If the contract pays a $30,000 installation fee pro rata to recorded completion, the amount earned so far is 90% x $30,000 = $27,000. If the contract instead requires all 20 units to be complete, nothing under that milestone is yet due, so read the signed terms before invoicing.Case study
Seen in the real world.
This illustrative and entirely fictional example follows Mariner Fitness, an invented gym chain. It ordered new exercise machines for a site opening. The supplier delivered all 30 machines and sent an invoice stating "installation complete." The manager saw the machines on the floor and approved payment. A later inspection found that three machines were not secured as the agreed plan required, and the serial-number list did not match the gym's asset register.
Mariner and the supplier reviewed each machine, documented which installation steps were finished and listed the three exceptions. Qualified technicians corrected the work and completed the required checks. For its next site, Mariner used a location-by-location installation record and kept final acceptance as a separate decision. The business did not deny that the supplier had done substantial work.
It made the remaining tasks visible so the opening plan, payment and maintenance records reflected reality. The finance team also changed its process so that depreciation on the machines started only when each machine was ready for use, not when the delivery note was signed. The asset register was corrected with the right serial numbers and locations, which later simplified a warranty claim on one machine.
Watch out
Common mistakes.
- Treating delivery or physical placement as completed installation. Fitting, connections and agreed checks can remain open.
- Using a signature as blanket acceptance when the signer only confirmed attendance. State exactly what the record verifies and list exceptions.
- Failing to capture serial numbers, locations and dates. That makes warranty claims and later maintenance harder.
Questions
People also ask.
Is an installation record the same as a commissioning certificate?
No. Installation records what was fitted; commissioning records tests that it performs against specified requirements. Contracts may require both.
Does a signed record mean final payment is due?
Only if the contract's payment milestone and acceptance rules are met. Check the signed terms and outstanding items.
Who should keep the record?
Both the provider and customer benefit from a copy, with the site, equipment and exceptions clearly identified.
