PAX vs E2 Shop System (Shoptech): Full ERP or Shop Tool?

Most manufacturers evaluating E2 Shop System (originally built by Shoptech Software) already know its reputation: solid quoting, reliable job tracking, 9,000+ installations since 1984. What they find out later is that E2 is a shop management system, not a full ERP. That means QuickBooks for accounting, a separate CRM for sales pipeline, and a third tool for HR. PAX replaces all three with one system. Whether that trade matters depends on how your shop runs.

It is also worth noting that E2 as a standalone product is being phased out. ECi Software Solutions acquired Shoptech in late 2020 and merged E2 into JobBOSS², its cloud-native successor. If you are evaluating E2 or Shoptech E2 today, you are effectively evaluating JobBOSS².

Key Differences

• E2 has best-in-class quoting and estimating for make-to-order job shops. If you run a custom machine shop, E2's historical job costing and one-click quote-to-order workflow is hard to beat.
• PAX includes full GAAP-compliant accounting with automatic general ledger entries on every transaction. E2's accounting module uses batch GL posting and most shops bypass it for QuickBooks.
• PAX includes a built-in CRM with pipeline management, email campaigns, and quote tracking. E2 offers basic contact management only.
• E2 is purpose-built for discrete, make-to-order manufacturing. PAX targets make-to-stock and simple assembly manufacturers (medical devices, CPG, supplements, electronics).
• PAX costs $350/month with no implementation fees. E2's total cost of ownership runs $10,000 to $60,000 upfront, plus $5,000 to $60,000 for implementation.

PAX and E2 Side by Side

Why E2 Users End Up Running Three Systems

E2's accounting module is its most criticized functional area. It uses batch posting to the general ledger rather than real-time posting (a pain to reconcile later), offers minimal drill-down into transactions, and according to user reviews, does not automatically relieve inventory and record cost of goods sold upon sale. The result: most E2 shops run QuickBooks alongside E2, treating E2 as the shop system and QuickBooks as the books.

That creates a second problem. Two systems means manual reconciliation, duplicate data entry, and no single source of truth for profitability. Add in the fact that E2's CRM is limited to basic contact management (no pipeline, no campaigns, no opportunity tracking), and many shops bolt on a third tool like HubSpot or Salesforce for sales management.

PAX was built to eliminate this stack. When your receiving clerk accepts a PO, the inventory quantity updates and the GL posts in the same moment. When a work order completes, finished goods cost flows to the balance sheet without a batch run or a QuickBooks sync. The CRM lives in the same database, so a sales rep quoting a customer sees live on-hand quantities and actual part costs without toggling to a second screen. For a detailed look at how this works, see PAX's ERP overview.

One Capterra reviewer of E2 summarized the accounting gap plainly: the module is functional for basic AR/AP but falls short of what most businesses need for serious financial management.

What $0 Implementation Actually Means

E2's implementation costs range from $5,000 to $60,000 depending on complexity, with timelines of one to four months. Shoptech provides a dedicated implementation specialist for the first six months, which is helpful, but the total investment is significant for a shop with 10-20 employees. Multiple E2 users stress that initial data setup must be perfect because, as one long-time user put it, the system does not go backwards well. Records that need to be corrected can create orphan entries and cascading data problems.

PAX charges nothing for implementation and nothing for data migration. The typical go-live timeline is three days. That is not a marketing claim, it is a function of scope: PAX targets simpler manufacturing operations with straightforward BOMs, so there is less to configure. A medical device manufacturer or supplement company with 15 employees does not need the same implementation runway as a 75-person machine shop with hundreds of active jobs. For context on what small manufacturers should expect to pay for ERP, see How Much Does Small Manufacturing ERP Cost in 2026?

Over five years, E2's total cost of ownership is estimated at roughly $75,000. PAX's Starter plan over five years is $21,000 with no additional fees. That gap narrows if you compare against E2's cloud pricing for a small team, but widens again when you add QuickBooks and a CRM tool to E2's side of the ledger.

What the ECI Acquisition Means for E2 Buyers

The biggest risk with E2 today is not the software. It is the transition. ECI acquired Shoptech in late 2020, launched JobBOSS2 in May 2021, and has been migrating E2 customers to the new platform since. Legacy E2 is still supported but no longer the development priority. The shoptech.com domain now redirects to JobBOSS2 content.

User reviews since the acquisition tell a consistent story about support quality. One Capterra reviewer noted that customer service dropped significantly after ECI took over. Forum discussions on Practical Machinist and Reddit reflect what the research describes as “cautious optimism tempered by uncertainty about ECI's long-term commitment.” If you buy in today, you are committing to ECI's roadmap, not Shoptech's.

PAX is independently owned and operated by its founder. There is no parent company redirecting the product, no platform consolidation in progress, and no migration to plan for. For a small manufacturer that values stability and support, that is worth weighing.

Quoting: Two Different Models for Two Different Shops

E2's estimating module is built for shops that price every job individually. It pulls historical data from past jobs, applies pre-set labor, overhead, and material rates, and generates custom quotes fast enough that shops use it to control their sales pace. Win/loss tracking on unanswered quotes gives real pipeline visibility inside the quoting workflow itself. For a make-to-order shop that quotes dozens of unique jobs per week, this is the core of the business.

PAX's quoting works differently because the manufacturers it serves work differently. PAX collects detailed job costing on every work order (materials, labor, overhead, outside services), which gives you the historical data to set accurate prices on your finished goods. Most PAX customers review and update pricing once or twice a year based on that data, then quote from established price lists rather than building a custom estimate for every order. One click converts a quote into a sales order, and if the customer is new, PAX creates their profile automatically. No re-keying, no second screen.

If your shop prices every job from scratch based on the specific work involved, E2's estimating engine is purpose-built for that. If your shop sells defined products at set prices and needs fast, accurate quoting with seamless order conversion, PAX handles that workflow well and customers consistently say so.

Shop Floor: Terminal Scanning vs. Dashboard and Time Tracking

E2 was built for shops where employees clock into jobs at dedicated terminals, scan barcodes on work orders, and track setup time versus cycle time at each operation. The shop floor data collection module feeds real-time job costing, so managers know exactly what a part cost to produce before it ships. That terminal-and-barcode workflow is central to how E2 shops run their floors.

PAX takes a different approach. Operators clock in and out for the day, clock in and out of individual jobs, log scrap, and issue materials through shop floor dashboards. Managers see real-time work order status and cost accumulation across materials, labor, overhead, and outside services. The difference is in the data collection method: E2 is built around barcode stations and terminal scanning at each machine. PAX is built around dashboards and direct time entries that feed the same cost tracking without requiring dedicated floor hardware.

Scheduling

E2 offers finite and infinite capacity scheduling with a visual whiteboard, drag-and-drop job assignment across machines and employees, plus bottleneck identification. That said, E2 users consistently report this module is the hardest to learn and most difficult to customize. Drag-and-drop was limited or absent in some versions, and changes across the schedule require significant manual work.

PAX takes a different approach: MRP and production planning driven by inventory usage history and sales volumes. Rather than scheduling individual jobs across machines, PAX helps you plan what to make and what to buy based on actual demand patterns. For shops running 5 to 30 active work orders, PAX handles the job. For shops juggling 50+ concurrent jobs across a dozen machines, E2's whiteboard visualization may offer more at-a-glance visibility, though its learning curve is steep.

Does E2 Shop System Include Accounting?

E2 includes an accounting module with AP, AR, general ledger, budgeting, and bank reconciliation. However, it uses batch posting rather than real-time GL updates, and its reporting capabilities are limited compared to dedicated accounting software. ECi offers a Centerpoint payroll add-on for multi-state payroll. In practice, E2's own user base is split: some shops use the built-in accounting, but a significant portion run QuickBooks alongside E2 through a Gold Certified integration. PAX takes the opposite approach: the GL updates the instant a transaction happens, not on a batch schedule (makes reconciling and reviewing accounts a lot more intuitive, since every GL transaction is directly traceable to the operation transaction that triggered it). Trial balance, income statement, balance sheet, AR/AP aging, and customer statements are all native. No QuickBooks required.

Does E2 Support QuickBooks Online?

No confirmed QuickBooks Online integration exists for E2 or JobBOSS². The connector supports QuickBooks Desktop via a Gold-certified sync. As more small businesses move to QuickBooks Online, this is a growing gap. If your shop is already on QBO and wants to keep it, E2 does not offer a clean path. PAX sidesteps this entirely by including native accounting, so there is no QuickBooks dependency in either direction. For shops weighing whether to keep QuickBooks alongside an ERP, see our comparison of QuickBooks vs. ERP for small manufacturers.

How Much Does E2 Cost for 10 Users?

Cloud pricing for E2/JobBOSS² starts at approximately $45–$150 per user per month. For 10 users, that is roughly $450–$1,500 per month in subscription fees alone, before implementation costs of $5,000–$60,000. On-premise licenses started at $4,995 with annual maintenance fees of 15–25% of the license cost. PAX's Growth plan covers up to 20 users at $900/month with no implementation cost and no per-user pricing. See PAX Pricing for current details.

The Bottom Line

E2/JobBOSS² could be a good option if you run a discrete, make-to-order job shop or machine shop with 50–100 employees, you quote dozens of custom jobs per week, your operators need terminal-based shop floor tracking, and you are comfortable running QuickBooks separately for accounting. E2's quoting, job costing, and shop floor modules are purpose-built for that workflow.

Choose PAX if you are a make-to-stock or simple assembly manufacturer with 5–50 employees, you want accounting, CRM, and ERP in one system without managing integrations, you need lot traceability for regulated products, or you need to go live in days rather than months. PAX is not built for high-mix custom job shops, but for manufacturers producing defined products with manageable BOMs, it eliminates the three-system problem that E2 shops live with. The simplicity PAX offers is a breath of fresh air.
