FastCons vs Acumatica Construction Cloud ERP
What is the core difference between FastCons and Acumatica Construction?
FastCons is FastWork’s construction project management solution, focused on the job site: plans, schedules, quantities, materials, contracts, site diaries and attendance. FastCons Next adds accounting, inventory, purchasing, sales and manufacturing on the open-source ERPNext platform. Acumatica Construction Edition is a cloud ERP from Acumatica (USA) with construction built into the core alongside finance, purchasing, inventory and projects.
In short, FastCons works from the job site up to the office, while Acumatica works from a company-wide ERP platform down to the job site. The two approaches serve different stages and scales, so the right question is not “which is better” but “which fits the company at this stage”.

According to FastWork’s website, FastCons serves general contractors, subcontractors and project management boards in construction, MEP, interior fit-out, transport infrastructure and industrial works, with more than 3,500 companies using it. The cloud edition runs on web and mobile. The Enterprise plan is published at VND 200,000 per user per month with a minimum of 10 accounts, and License and Private Cloud plans are quoted on request.
FastCons suits construction companies that want to digitize the job site quickly with a low upfront cost, mainly do construction and operate as one legal entity. For companies already using it well, continuing with FastCons or upgrading to FastCons Next is a sensible choice.
Which companies is Acumatica Construction a good fit for?
Acumatica Construction Edition suits mid-size and large construction companies running many projects in parallel, with many site users and a current or planned multi-company structure. Contracts, estimates, subcontracts, change orders, progress billing, retainage and work in progress run on the same database as finance, purchasing and inventory. The Unlimited Users model lets the entire site team use the system without per-user fees. Learn more about Acumatica ERP for construction.
How do FastCons and Acumatica Construction compare on 10 criteria?
The table below summarizes public information at the time of writing (October 2026). FastCons information comes from FastWork’s website and its FastCons Next introduction webinar. “Not published” means it was not found in public materials, not that the product lacks the capability.
| Criteria | FastCons / FastCons Next | Acumatica Construction |
|---|---|---|
| Platform architecture | Construction management module combined with open-source ERPNext (FastCons Next) | Unified cloud ERP with construction in the core |
| Accounting | FastCons Next: Vietnamese Circulars 200 and 133 | VAS localization via the implementation partner |
| Contracts, certification | Owner and subcontract contracts, staged certification | Contracts, subcontracts, progress billing |
| Change orders | Added BOQ items or contract appendices | Change orders with an approval workflow |
| Cost at completion, project cash flow forecast | Not published | Built in |
| Multi-company, consolidation | Not published | Built in |
| Customization | Configuration on SaaS, with License and Private Cloud plans | Configuration and coding via Customization Projects, separate from the core |
| Licensing model | Per user (Enterprise plan VND 200,000/user/month) | Unlimited Users, based on application bundle and resource usage |
| Site mobile | Web, iOS, Android | Web, iOS, Android |
| AI | Not published | AI Studio, AI Assistant, document recognition |
The “not published” items are questions companies should raise with the vendor, along with a request for a demo on real data.
How do accounting and project finance differ between the two?
With FastCons, accounting can run in separate accounting software or in the FastCons Next accounting module, presented as following Circulars 200 and 133 with financial statements by company and by project. Project profit and loss relies on tagging documents with project codes. Since FastCons Next has been in development since 2024, companies should ask for references from customers already running accounting on it.
With Acumatica Construction, the general ledger, payables and receivables, contracts and project costs sit on one platform by design. Every site transaction updates project financials at the same time, so budget versus committed versus actual, estimated cost at completion and monthly cost forecasts can be tracked in real time.
How does customization for specific needs differ?
FastCons Cloud is SaaS: companies configure predefined parameters, and new features depend on the vendor’s roadmap. This keeps deployment fast and costs low. For specific processes, companies should clarify the customization scope of each plan with FastWork.
Acumatica is also a cloud ERP, but companies and partners can build coded extensions with Customization Projects, kept separate from the core. Payment application formats, overhead allocation or integration with estimating software and banks can be met while the system still follows two major releases a year.
What should a company consider as it grows into several entities?
Construction companies with VND 500-2,000 billion in revenue often have subsidiaries, joint ventures, factories and a materials trading arm. The system then needs multi-entity, intercompany transactions, multi-currency and fast consolidated reporting. Acumatica supports these needs together with manufacturing and distribution modules, and Nucleus Research places it in the Leaders quadrant of the SMB ERP Technology Value Matrix 2026. With FastCons, these are criteria to ask the vendor to demonstrate specifically.
Acumatica Construction & Oracle NetSuite:
Which platform fits your construction business?
See how S4 implements construction ERP with accounting, projects and consolidation on one system.
How should companies compare the cost of the two solutions?
FastCons publishes per-user pricing for its Enterprise plan, plus a one-time setup fee based on user count. Acumatica does not publish an official price list; pricing depends on the application bundle and resource usage. Based on S4’s implementation experience in Vietnam, a subscription for a 100-user contractor typically falls between USD 20,000 and 50,000 per year, excluding implementation, and does not change as users are added.
Because the pricing structures differ, compare them on the same 3-5 year TCO: licenses, implementation, integration, any accompanying accounting software, operating staff, time spent reconciling data, and the cost of adding companies, projects or users.
Which solution should a company choose?
Start with 5 questions that leadership needs to answer in the system:
- Is the project making or losing money? Can I see the actual profit and margin of each project today?
- How will the project end? Can I see the estimated cost at completion and expected final profit?
- Is the budget being exceeded? Can I see budget, committed and actual cost for each project?
- Where is the cash, and where will it run short? Can I see what has been invoiced, collected and still receivable, and the projected cash flow?
- How many companies will we have in 3 years? Can the system consolidate them without Excel?
Then ask both vendors to demonstrate against the company’s own processes and data. The best choice is the solution that answers the most questions at the most reasonable total cost over 3-5 years.
Conclusion
FastCons and Acumatica Construction start from two different approaches. FastCons suits companies that want to digitize the job site quickly, with a low upfront cost, within one legal entity. Acumatica Construction suits mid-size and large companies that need real-time project finance, many site users, the ability to code for specific needs and a multi-company structure.
As construction companies in Vietnam plan their technology for 2027, compare the two solutions on real data and on the same TCO framework, rather than on feature lists or first-year license price alone.
