Why two equipment quotes never match: five ambiguities to close in an RFQ
When two hire quotes come back far apart, it is rarely price, it is scope your RFQ left ambiguous and each supplier guessed differently. The five ambiguities to close so the quotes are comparable and the final invoice stops surprising you.

When two hire quotes for the same machine come back far apart, the instinct is that one supplier is dearer. It almost never is. The gap is that your request left five things unsaid, and each supplier filled the silence with a different assumption. Close those five, and the quotes line up against each other and the final invoice stops springing surprises. An RFQ is not a request for a price, it is a specification tight enough that two honest suppliers have to quote the same thing.
1. The exact configuration, not the class
A twenty ton excavator is not a specification. Steel tracks or rubber, cab or canopy, quick coupler, long reach, machine control, the attachments you expect to swing. Leave the configuration open and one supplier quotes the base machine while another quotes the version you actually need, and the difference shows up later as a mid hire swap, which is billed as a second mobilization. Specify the configuration, including the attachments, not just the class.
2. Wet or dry, and who carries the idle
Wet hire, the machine with an operator, and dry hire change who carries operator cost, supervision and idle time. For short or uncertain scopes, wet hire is often the cleaner buy once mobilization, idle and the cost of finding an operator are counted. For long, steady work with your own crews, dry hire usually wins. If you do not say which you want, you will get the two priced on different bases and no way to compare them.
3. Mobilization, both ways, and the swap policy
Transport is charged in each direction, and every spec change or breakdown swap is another mobilization. Ask for mobilization in and out as named lines, and ask what a swap costs, so a machine that turns out wrong for the ground does not arrive with an unbudgeted transport bill attached. The cheapest looking quote is often the one that left mobilization out.
4. Standby and idle
When the machine sits because survey, permits or trucking are late, is that time charged, and at what rate? Standby is a real and separate line, and the time to agree it is in the RFQ, not on the invoice when the crew has been waiting on a permit for two days. Ask suppliers to state their standby rate up front.
5. Fuel and the condition at off hire
The cleanest fuel policy is full to full: rent it full, return it full, no argument. Define full, define clean, and say who pressure washes a mud packed undercarriage. The disputes that bite at off hire are condition disputes, and undercarriage and glass are the expensive ones, so photograph all corners, the undercarriage and the hour meter at delivery.
Close the five and the quotes become comparable
- State the full configuration and the attachments, not the machine class.
- Say whether you want wet or dry hire, so idle and operator cost sit on one side.
- Ask for mobilization in and out, and the swap cost, as named lines.
- Ask for the standby rate before the machine arrives.
- Set a full to full fuel policy and define the return condition, with delivery photos.
Give us the configuration, the duration, the site access and whether you want an operator, and we will quote with mobilization, standby and fuel on the page, so the number you approve is the number you pay.
