Head-to-Head Comparison: Trackara Pro vs ARI
Here's a side-by-side look at how Trackara Pro and ARI stack up. This isn't a close contest -- it's a basic invoicing tool vs a complete business management platform:

|---|---|---|
| Platform Type | All-in-one business platform | Basic invoicing tool |

The comparison table makes the gap clear. ARI does one thing -- invoicing. Trackara Pro does everything a mechanic needs to run a complete business. It's the difference between buying a screwdriver and buying a full toolbox.
Pricing: You Get What You Pay For
ARI's appeal is straightforward: it's a lower-cost tool because it does less. If all you need is to punch in an invoice and send it, ARI's price tag might look attractive on the surface.
But here's the problem: invoicing is only one piece of running a business. When you use ARI, you still need separate tools for everything else -- scheduling, mileage tracking, time tracking, analytics, inventory, CRM, diagnostics. Those costs add up fast.
The Real Cost of "Cheap" Invoicing:
- ARI for invoicing
- + A separate mileage tracking app ($5-10/mo)
- + A scheduling tool ($15-30/mo)
- + A time tracking app ($5-15/mo)
- + Spreadsheets or another tool for inventory
- + No business analytics at all
- + No OBD2 integration at all
- = Multiple subscriptions, scattered data, no unified view of your business
Trackara Pro is $49.99/month with everything included. All features. No tiers. No upsells. No per-user charges. One app, one subscription, one place where all your business data lives together.
When you factor in the cost of cobbling together multiple apps to match what Trackara Pro offers out of the box, the "cheaper" invoicing tool often ends up costing you more -- in money, in time, and in the frustration of jumping between disconnected tools.
What About the Mileage Deductions You're Missing?
Here's the cost ARI users rarely think about: lost tax deductions. ARI doesn't track mileage. If you're a mobile mechanic driving 25,000+ business miles per year, Trackara Pro's built-in IRS-compliant mileage tracking can generate $17,500 in deductions at the 2026 standard mileage rate of $0.70/mile -- translating to $4,200+ in actual tax savings. That single feature pays for your Trackara Pro subscription more than 7 times over.
Where Trackara Pro Wins
If you're looking for an ARI alternative that does more than just invoicing, here are the six areas where Trackara Pro has an overwhelming advantage:
1. Complete All-in-One Platform vs Single-Purpose Tool
This is the fundamental difference. ARI is an invoicing tool. Trackara Pro is an entire business management platform. With Trackara Pro, you get invoicing, quotes and estimates, work orders with digital signatures, time tracking, mileage tracking, OBD2 diagnostics, business analytics, parts inventory, scheduling, and full CRM -- all integrated in a single app. No more juggling five different tools and manually copying data between them.
2. Mileage Tracking Worth $4,200+/Year in Tax Savings
ARI has no mileage tracking whatsoever. For mobile mechanics, this is a critical gap. Trackara Pro's built-in mileage tracking automatically logs every business trip with IRS-compliant records. At the 2026 standard mileage rate, 25,000 business miles means $17,500 in deductions and $4,200+ in real tax savings. This single feature that ARI lacks could be worth more than your entire annual software budget.
3. OBD2 Diagnostics Built Right In
Trackara Pro's integrated OBD2 diagnostics lets you scan vehicles, read and clear codes, view live data, and attach diagnostic results directly to work orders -- all from the same app you use for invoicing. ARI doesn't offer anything close to this. Without integrated diagnostics, you're using a separate scan tool app and manually noting codes somewhere else. Trackara Pro eliminates that friction completely.
4. Work Orders and Digital Signatures
ARI creates invoices. But what about the work order that comes before the invoice? Trackara Pro's work order system lets you create detailed job documentation, capture customer authorization with digital signatures on-site, and then seamlessly convert completed work orders into invoices. It's a professional workflow that ARI simply can't replicate because it wasn't designed to.
5. Business Analytics: Know Your Numbers
How much revenue did you generate last month? What's your average job value? Which services are most profitable? ARI can't answer any of these questions. Trackara Pro's business analytics gives you real-time dashboards showing revenue trends, profit margins, job performance, and growth metrics. You can't grow what you can't measure, and ARI gives you zero measurement tools.
6. Mobile-First Design with Offline Mode
Trackara Pro was built mobile-first for iPhone, iPad, and Android. Every screen, every workflow, and every tap was designed for a mechanic working in the field. It works fully offline -- in garages, basements, rural areas, and anywhere cell service is spotty. When you reconnect, everything syncs automatically. ARI was designed primarily as a basic invoicing interface, not as a comprehensive field-ready mobile platform.
Where ARI Might Work
We believe in giving you an honest comparison. Here are the scenarios where ARI could be the right choice:
1. You Literally Only Need Invoicing
If your entire software need begins and ends with "create an invoice and send it to a customer," ARI handles that. It's a focused tool for a single job. If you have no need for work orders, scheduling, mileage tracking, diagnostics, analytics, inventory, or CRM -- and you're confident you won't need them in the future -- ARI's simplicity might appeal to you.
2. You're Just Getting Started and Doing Very Few Jobs
If you're doing a handful of side jobs per month and aren't yet running a full-time mobile mechanic business, a basic invoicing tool might feel like enough for now. However, most mechanics who start with a basic tool end up outgrowing it within a few months as their business picks up and they realize they need scheduling, tracking, and proper business management.
3. Absolute Lowest Possible Software Spend
ARI may have a lower sticker price. If your only goal is to minimize the number on your software invoice line item -- regardless of the value you get back or the features you're missing -- ARI costs less upfront. Just remember: you get what you pay for, and the features you're missing (especially mileage deductions) could cost you far more than the savings.
The Pattern: ARI works if invoicing is genuinely the only thing you need software for. But the moment you need work orders, scheduling, mileage tracking, diagnostics, analytics, inventory, or CRM -- even one of those -- you'll need additional tools, and Trackara Pro's all-in-one platform at $49.99/month becomes the smarter investment.
Who Should Choose Trackara Pro
Trackara Pro is the right choice if you:
- Want one app for everything -- invoicing, quotes, work orders, scheduling, time tracking, mileage tracking, OBD2 diagnostics, business analytics, parts inventory, and CRM all in one place
- Are a mobile mechanic who needs a platform built for field work with offline mode and mobile-first design
- Drive business miles and want automatic IRS-compliant mileage tracking that can save you $4,200+/year in tax deductions
- Perform on-site diagnostics and want OBD2 scanning integrated directly into your work orders
- Want to grow your business with analytics that show you revenue trends, profit margins, and which services are most profitable
- Are tired of juggling multiple apps and want all your business data in one unified platform
- Need professional work orders with digital signature capture for customer authorization
- Have outgrown basic invoicing and need a real business management platform
If even two or three of those describe you, Trackara Pro is the clear upgrade from ARI.
Who Should Stick with ARI
ARI may be sufficient if you:
- Only need to create basic invoices and have no need for work orders, scheduling, or any other business management features
- Don't drive to customer locations and therefore don't need mileage tracking
- Don't perform diagnostics or have a completely separate workflow for OBD2 scanning
- Don't track your time on jobs and don't bill hourly
- Don't need business analytics and are comfortable not knowing your revenue trends or profit margins
- Are doing very few jobs per month as a side hustle and don't plan to grow
For this narrow use case, ARI does the job. But be honest with yourself: if you're running a real business -- or planning to -- you'll outgrow a basic invoicing tool fast. Most mechanics who start with ARI end up needing more within months.
Frequently Asked Questions
What is ARI (Auto Repair Invoice) and how does it compare to Trackara Pro?
ARI (Auto Repair Invoice) is a basic invoicing tool designed for auto repair shops to create and send invoices. It handles simple invoice creation and basic vehicle/client records. Trackara Pro is a complete all-in-one business platform that includes invoicing plus work orders, quotes, time tracking, mileage tracking, OBD2 diagnostics, business analytics, parts inventory, scheduling, CRM, and more -- all in a single mobile-first app for $49.99/month.
Can ARI track mileage, manage work orders, or run OBD2 diagnostics?
No. ARI is focused primarily on invoice creation and does not include mileage tracking, work order management, OBD2 diagnostics, business analytics, time tracking, parts inventory, or scheduling. If you need any of these features, you would need separate apps alongside ARI -- or you can get everything in one place with Trackara Pro.
Is ARI cheaper than Trackara Pro?
ARI may have a lower sticker price since it is a basic invoicing tool. However, when you factor in the cost of all the separate tools you'd need to replace the features ARI lacks -- mileage tracking apps, scheduling software, inventory management, diagnostics tools, and analytics platforms -- Trackara Pro's $49.99/month for everything in one app is significantly more cost-effective. Plus, Trackara Pro's mileage tracking alone can save you $4,200+/year in tax deductions that ARI simply can't provide.
Should I switch from ARI to Trackara Pro?
If you've outgrown basic invoicing and need a complete business management platform, yes. You can start a free trial of Trackara Pro and begin entering your clients and vehicle data. Many mechanics run both side by side during the transition. Once you're comfortable with Trackara Pro, you can cancel ARI and manage your entire business -- invoicing, work orders, scheduling, mileage, diagnostics, analytics, and more -- from one app.
Who should use ARI instead of Trackara Pro?
ARI may be sufficient if you literally only need to create basic invoices and nothing else -- no work orders, no scheduling, no mileage tracking, no diagnostics, no business analytics. However, most mechanics quickly discover they need more than just invoicing to run their business efficiently. If you need even one additional feature beyond basic invoicing, Trackara Pro's all-in-one platform at $49.99/month is the better investment.

The Bottom Line: Invoicing Tool vs Business Platform
ARI does one thing and it does it simply: basic invoicing. If that's genuinely all you need, it works. But for most auto repair professionals -- especially mobile mechanics -- invoicing is just one small part of running a business.
You also need to manage work orders, track your time, schedule your jobs, log your mileage for tax deductions, run diagnostics, manage your parts inventory, understand your business performance, and maintain professional client relationships. Trying to do all of that with a basic invoicing tool plus a patchwork of other apps is slow, frustrating, and expensive.
Trackara Pro replaces all of it with a single, mobile-first platform built specifically for mechanics who work in the field. Invoicing, quotes, work orders, time tracking, mileage tracking, OBD2 diagnostics, business analytics, parts inventory, scheduling, and CRM -- all for $49.99/month with offline mode and digital signatures included.
The question isn't whether Trackara Pro does more than ARI -- it obviously does. The question is whether you're ready to stop managing your business with a basic invoicing tool and start managing it with a real platform.
Next Steps:
- Start your free trial of Trackara Pro
- Set up your invoicing (everything ARI does, and more)
- Explore work orders with digital signatures
- Turn on automatic mileage tracking from day one
- Connect your OBD2 adapter for integrated diagnostics
- Check your business analytics dashboard after your first week
