Methodology
How we test
DealStackLab exists because every other 'best software' list is a vendor grading itself or a thin AI listicle. Here is exactly how our verdicts are made - and the rubric behind every score.
The process
- 01
We open a real account
Every review starts with a paid account or a genuine free trial, signed up with our own card - never a vendor-provided demo or a sponsored walkthrough. We see the same onboarding, paywalls, and upsells you would.
- 02
We run the real workflows
We import actual properties, build real lists, run the calculators, and trigger the real features - finding leads, skip tracing, analyzing deals. Anything that costs money to send (mail, dialer) we inspect but don't spend, and we say so.
- 03
We capture our own screenshots
Dated screenshots from inside the live account, so you see exactly what we saw - the real numbers on a real address, not a marketing mockup.
- 04
We verify pricing at the source
We log the base subscription (monthly and annual), the per-use credits, overages, and per-seat costs straight from the vendor's own checkout, and stamp the date we checked. List price lies; the true all-in cost is what we publish.
- 05
We write the verdict - including who it's NOT for
What the tool is genuinely great at, the honest caveats, and the situations where you should pick something cheaper or skip it entirely. An honest 'not for you' is more useful than another five stars.
- 06
We re-verify, and scores get re-earned
We re-check pricing monthly and update the 'last verified' date. When a product raises prices, ships a fix, or its data coverage changes, the score changes with it. A high score has to be re-earned.
How we score
Every tool gets a single score out of 5. It is expert judgment from real use, anchored to five consistent dimensions - not a black-box formula, and never for sale. Here is what goes into it.
Capability
Does it do its core job genuinely well in real use - not just on the feature list?
True cost & value
Sticker price plus per-use credits, overages, and what's gated behind paywalls. Is it worth it at the all-in cost?
Reliability
Does it actually work - including the first run? Bugs, broken onboarding, and downtime count against the score.
Honesty
How straight is the product itself - hidden costs, misleading 'free' tiers, or stats that don't mean what they imply?
Fit
How clearly does it suit a specific buyer? A focused tool that nails one job can outscore a bloated all-in-one.
What the score means
| Score | Band | What it means |
|---|---|---|
| 4.5 - 5.0 | Exceptional | Does its job extremely well at fair, honest pricing. Few real caveats. We'd recommend it without hesitation for the right buyer. |
| 4.0 - 4.4 | Strong | Clearly recommendable, with real trade-offs worth knowing (price, a gap, a quirk). The bulk of genuinely good tools land here. |
| 3.0 - 3.9 | Useful but compromised | Does something well but is held back by cost, reliability, or a meaningful limitation. Right for some, wrong for many. |
| Below 3.0 | Hard to recommend | Overpriced, buggy, misleading, or beaten by cheaper options for most people. We'll tell you what to use instead. |
A focused tool that nails one job can outscore a broader one that does many things adequately - we score how well it serves its buyer, not how long the feature list is.
What we will not do
Rankings are never for sale. No vendor can pay for a score, a placement, or the removal of a caveat - and if one offers, the answer is no. We don't take vendor demos in place of real testing, we don't publish AI-generated listicles, and we disclose our affiliate relationships on every page (see our FTC disclosure and editorial policy).
FAQ
- Do the companies you review pay you?
- We earn affiliate commissions on some outbound links, which fund the accounts and test runs - but a vendor can never pay for a score, a placement, or the removal of a caveat. We form verdicts before any affiliate relationship is considered. See our FTC disclosure.
- How are your scores calculated?
- Each tool is judged on five dimensions - capability, true cost and value, reliability, honesty, and fit - from real hands-on use, then placed on a 5-point scale. It's expert judgment anchored to consistent criteria, not a black-box formula, and the score is re-earned whenever the product changes.
- Do you use AI to write your reviews?
- No. We don't publish AI-generated listicles or recycled marketing. Every review is written from our own hands-on testing, with our own screenshots and dated, source-verified pricing.
