Three quotes for the same project can differ by a factor of two. Almost always the difference is not margin, it is what each one includes and what it quietly leaves out.
What a real estimate itemizes
Materials with quantities and sizes, not just a category. Plants listed by species and container size. Labor separated from materials. Timeline. Payment schedule. And explicitly, what is excluded.

A single number on a page is not an estimate. It gives you no way to compare against another bid and no way to know what happens when something changes.
Where cheap bids save money
Soil preparation is the most common omission, because it is invisible when finished and it is the largest determinant of whether planting survives.
Others: drainage behind retaining walls, base depth under hardscape, edging on gravel and decomposed granite, and irrigation for the establishment period. Every one of those is a cost that arrives later if it is skipped now.
Questions that surface the gaps
Ask what happens if they hit rock, which on the west side of the metro they will. Ask who is responsible if plants die and over what period. Ask whether cleanup and disposal are included. Ask whether permits are included where relevant.
For irrigation, ask for the TCEQ irrigator license number, since Texas requires one. A bid substantially below the others has often omitted licensing and permitting entirely.
Comparing on the same basis
Ask each bidder to quote the same scope. If one includes soil amendment and another does not, the numbers are not comparable and the cheaper one is not cheaper.
Then weigh the parts you cannot see. Base preparation, drainage and soil work are where a project either lasts a decade or needs redoing in two years, and they are exactly the lines that are easiest to trim to win a bid.
Understanding allowances and unit prices
An allowance is a placeholder for something not yet chosen, commonly plants or stone. It is not a fixed price, and if your final selection costs more, the difference is added.
Ask what the allowance assumes. A stone allowance based on the cheapest available material will not cover the stone you actually liked, and that gap appears late in the project when you have least leverage.
Unit prices are the other useful thing to request: cost per square foot of paving, per plant of a given size, per linear foot of edging. They let you compare bids that are structured differently and adjust scope intelligently if the total comes back high.
Payment schedules and what is reasonable
A deposit covering materials is normal. Progress payments tied to defined milestones are normal. A demand for the majority up front is not, and it removes your only real leverage.
Tie the final payment to a walkthrough where you agree the work is complete, and keep it large enough to matter, typically around ten percent. That final payment is what gets the punch list finished.
Get any change in writing before it happens, including the price. Verbal change orders on a landscape project are the most common source of disputes, because both sides remember the conversation differently once the invoice arrives.
Reading between the lines
A quote that is dramatically lower than the others has almost always removed something. Compare the scope line by line rather than the totals, and look specifically for soil preparation, base depth, drainage and edging.
Vague language is a warning: “prepare area as needed” or “install plants per plan” without a plant list gives the contractor latitude and you no recourse.
Conversely, a quote that specifies base depths, compaction, fabric, drainage details and plant sizes is written by someone who intends to do that work. The detail itself is evidence, which is why the most useful thing you can do with three bids is read the specifications rather than the prices.
Common questions we get about this
Three come up almost every time.
Can I do this myself? Usually part of it. The diagnostic work and the finishing details are where experience shows, and the preparation underneath is where shortcuts cost the most. Most homeowners who do it themselves succeed on the visible work and struggle with base preparation, drainage and timing.
When is the best time? In Central Texas, almost always autumn. Soil is still warm, air has cooled, and anything planted or installed has months to settle before summer stress arrives. Spring works but races the heat.
What does it cost? Any number quoted without seeing the property is a guess, because our two soils, the slope and the access change the work substantially within a few miles. What we can say is that the invisible preparation is where the real cost sits, and where the cheapest bid has usually economized.
