In short

Its published prices are $5,000 for one reviewed month; $24,000/year for annual workspace access.

What it is
What TDR Preflight is
A service and workspace aimed at MAS holders who bill hourly or labor-hour services. It takes a month of sales, produces an SRP file that has been reviewed, and adds an evidence package. The customer reviews the output and submits it.
Its page is written for a narrow case: it lists the transaction types its output supports and says several others block.
Access
How you get in
Its page sells one reviewed month at a fixed price. The annual workspace is software access, and its page says any ongoing expert preparation is scoped separately. Ask it how an engagement starts and what it needs from you about your contract and data.
Pricing
Pricing
TDR Preflight publishes $5,000 for one reviewed month; $24,000/year for annual workspace access. Because SRP takes a report every month, a holder buying one reviewed month at a time pays that figure for each month. The annual workspace is priced by the year for workspace access, and its page says ongoing expert preparation is scoped separately. TDR Prep's plans, for comparison, run $99, $149 or $249 a month.
Strengths
What it does well
It is specific. A services holder reading its page knows quickly whether the offer fits their contract, and the evidence package gives a documented record of how the month was built.
It reads CSV or XLSX files, or QuickBooks Online on a read-only connection.
Limits
Where it stops
Its page says the supported output is narrow and that several transaction types block. A holder with product sales, or with a transaction type outside that list, needs another route for those lines.
Ask TDR Preflight which of your transaction types it accepts, what a second month costs once the first is reviewed, and what you keep if you stop using the workspace.
Fit
Pick TDR Preflight if
- Your schedule bills hourly or labor-hour services only.
- You want a reviewer and an evidence package behind a difficult month.
- A project price for that month fits your budget.
Not a fit
Look elsewhere if
- Your schedule includes products, or mixes products and services.
- You want a monthly price you can plan the year around.
- You want to run your own data through the file rules before paying anyone.
Us
How TDR Prep differs
TDR Prep is self-serve software rather than a reviewed engagement. You import the month, map each SKU once, and see every line SRP would reject before the file is produced, then download it and upload it yourself. Plans start at $99 a month. TDR Prep's mapping is built around catalog items. TDR Prep is opening soon; once it opens, a services-only holder can run one month through the free validation and see whether every line clears before choosing between the two.
